7th Gen Corvette Stingray: What Owners Say

  • With the C7 generation, Chevrolet turned up the level of individuality by introducing a more diverse catalog of paint, upholstery, and wheel options together with a series of visual packages. This, coupled with the car's more aggressive design direction, means that it has evolved into a more head-turning product.
  • The LT1 finally brings the Corvette badge into the modern age of direct injection and valve timing, which brings with it a new level of performance. You no longer need to stretch to the Z06 model to get a true feeling of speed.
  • The C7 is still a fairly young model, so your chances of finding a clean and low-mileage model are significantly higher.
  • While the LT1 may be a significantly more modern powertrain, it is prone to developing carbon build-up from the direct fuel injection system. Even worse are the collapsing lifters that are a result of the cylinder deactivation program aimed at saving fuel.
  • While the interior appears more premium than ever before, it is still put together with abundant use of plastics, which cheapens the overall feel of the cabin. Squeaks and rattles are noticeable while driving.
  • Owners lament that, unlike previous Corvette models, the cargo space is not as generous which can make a weekend getaway a bit more challenging. The convertible in particular has just about enough room for two mid-size luggage cases.

Seventh Generation Chevy Corvette Stingray Coupe Facelift

Like the generation before it, Chevrolet opted to not facelift the Corvette Stingray C7 throughout its six-year lifespan, but there were several visual packages added to later model years in a bid to make the sports car more visually appealing and distinctive.

Engine, Transmission and Drivetrain

The 7th-gen Chevrolet Corvette Stingray coupe and convertible were only available with the LT1 6.2-liter V8. The supercharged LT4 and LT5 were reserved for the Z06 and ZR1, respectively. This naturally aspirated unit could be had in two states of tune and paired with one of three transmissions. This engine debuted in the C7 Corvette and was only extended to the Camaro SS.

The LT1 is the official successor to the LS3 used in the C6-generation of the Corvette. To give the all-aluminum small-block V8 a more modern persona, GM installed new cylinder heads, a tri-lobe camshaft, and new pistons. A high-pressure oil pump, direct fuel injection, and variable valve timing technology mean that it was able to squeeze out 455 horsepower and 460 lb-ft of torque to the rear wheels via your choice of a Tremec TR-6070 seven-speed manual or 6L80 six-speed automatic torque converter transmission. This was only available in 2014 before being exchanged with the 8L90 eight-speed automatic. If you equip the performance exhaust, there is a slight bump in outputs to 460 hp and 465 lb-ft. The modern LT1 is generally a dependable powertrain, but you will need to look out for carbon build-up, collapsing lifters, and bending pushrods. The eight-speed automatic transmission can also suffer from shuddering or vibrating.

2014-2019 Chevrolet Corvette Stingray Coupe 7th Gen Real MPG

Despite the powertrain being fitted with direct injection, variable valve timing, and Active Fuel Management - GM's version of cylinder deactivation - the LT1 is not that much more frugal compared to the LS3. The seven-speed manual brings in an EPA-estimated consumption figure of 16/25/19 mpg city/highway/combined while the six-speed and eight-speed automatic return an estimate of 16/27/20 mpg and 15/25/18 mpg respectively. While previous Corvettes usually had mpg estimates that were more preferable compared to their more luxurious but evenly paced European counterparts, this was the era of downsizing and turbocharging, which means the likes of the Mercedes-AMG GT S and Porsche 911 GTS are able to convey better mpg estimates from the EPA.

These figures are then provided on the EPA website. Real-world figures are not available for certain models due to a lack of sales, or not enough people partaking in this after-sales survey.


Like Corvette models of previous generations, the Corvette Stingray coupe and convertible were not crash-tested by the NHTSA but in the safety department, its structure is said to be a huge step forward compared to the C6. This model employs an aluminum space frame with carbon-nano-composite underbody panels. All trim groups also feature traction and stability control, tire pressure monitoring, auto-on xenon headlights with LED daytime running lights, front and side airbags, cruise control, and a backup camera. 2LT trim groups feature electrochromatic mirrors and an advanced theft-deterrent security system.

7th Generation Chevrolet Corvette Stingray Coupe Trims

The C7-generation Chevrolet Corvette only has one trim option with three equipment level groups consisting of 1LT, 2LT, and 3LT. All trims are comprehensively equipped with dual-zone climate control, smart keyless entry, and electrically adjustable seats and mirrors. Beyond these groups, some optional packages affect the performance and visuals of the Corvette. The C7 Grand Sport coupe and convertible were introduced to the range in 2017 as a more driver-focused offering. Like the C6, the introduction of this trim was essentially a replacement for the Z51 performance package.

Both the Stingray and Grand Sport trims were not treated to many unique models as these were reserved for the Z06 and ZR1, but there were a couple of special creations:

2015 Chevrolet Corvette Stingray Pacific and Atlantic Design package: These two visual packages provide the Corvette with a distinctive visual appearance. The Pacific coupe features a full-length dual racing stripe with some carbon elements and Z51-style wheels, while the Atlantic convertible adds some aerodynamic components with a hood stinger stripe. Both cars benefit from premium interior trimmings.

2017 Chevrolet Corvette Sport Collector Edition: To celebrate the arrival of the Grand Sport trim, Chevrolet produced 1,000 of these limited units featuring the iconic Tension Blue fender hash-marks, two-tone Tension Blue leather upholstery with a Grand Sport logo embossed on the headrest, blue contrast stitching, and a numbered dash plaque.

2018 Chevrolet Corvette Carbon 65 Edition: 65 years of the Corvette was celebrated by a small number of these special Grand Sport coupes and convertibles. This featured unique fender stripes, decals on the doors, black wheels with blue brake calipers, Jet Black suede interior upholstery with blue contrast stitching, and a plethora of unique badges. Carbon fiber parts consisted of a refinished hood and roof, spoiler, and steering wheel rim.

With the 1LT trim package you get smart keyless entry with push-button start, heated and electrically adjustable door mirrors, dual-zone climate control, an electronically adjustable multifunction steering wheel, and eight-way power-adjustable GT bucket seats with Moulan leather upholstery. For entertainment purposes, all cars feature the eight-inch touchscreen infotainment system with USB, Bluetooth connectivity, and XM Radio. This is connected to a nine-speaker Bose premium audio system and acts as a display for the backup camera.

In the 2LT group, the Corvette gains color-keyed center console and door armrests, electrochromatic mirrors, a head-up display, the 10-speaker Bose Centerpoint surround sound system, heating and ventilation for the seats as well as electrical adjustments for the bolster and lumbar, the memory package, and HD radio. 3LT adds navigation and extra leather trimmings.

Optional extras include the performance exhaust, Magnetic Ride Control with Performance Traction Management, a Carbon Flash spoiler and mirrors, red or yellow brake calipers, and competition sport or GT bucket seats with suede inserts. The Z51 package includes a larger set of Sterling Silver alloy wheels, a dry-sump oil system, performance gear ratios, an electronic limited-slip differential, larger brakes with slotted rotors, a firmer suspension with revised shocks, springs, and stabilizer bars, cooling for the differential and transmission, and an aerodynamics package. For those who want to collect statistics on their driving, a performance data recorder was added to the 3LT group in 2015. The ZF1 package, consisting of a five-spoke aluminum wheel finished in Sterling Silver and a body-color spoiler was also introduced.

Minor changes to the 2017 model include the optional red seatbelts. You could also specify yellow or red contrast stitching for the 3LT trim group only if you specified the jet black interior. For this year, Chevrolet also introduced three limited interior packages for the 3LT. This consists of the Twilight Blue, Spice Red, and Black Suede themes.

As is the case with the C6-generation, Chevrolet introduced the Grand Sport as an individual trim, but it is essentially the Z51 package with some distinctive alterations. Like the Stingray, it is available in 1LT, 2LT, and 3LT trim groups and, apart from the additional performance enhancements and some visual cues, the standard features are the same. The most noteworthy package that is available for the Grand Sport is the Z07 Performance package, which caters to customers who want a more thrilling driving experience. This adds a carbon-ceramic high-performance brake system and a Z07-specific suspension with Magnetic Selective Ride Control.

Interior, Trim And Practicality

Chevrolet Corvette Stingray Coupe C Interior Overview Chevrolet
Chevrolet Corvette Stingray Coupe C Interior Overview

Compared to the C6-generation Corvette, the C7 offers its driver and passenger more space. With a headroom figure of 37.9 inches and legroom of 43 inches, this creates enough room for even those over six foot to feel comfortable. Despite maintaining a fastback coupe body style, this generation offers less trunk space at 15 cubic feet, which is enough to fit in two medium-sized suitcases. The convertible doesn't fare much better with its 10 cubic feet of space.

While plastic trimmings are still prevalent, Chevrolet certainly stepped up the cabin quality thanks to the use of more leather upholstery along the dash and doors. Cars fitted with the optional carbon fiber trimmings are also likely to feel a bit more upmarket. There are five leather upholstery options for the C7-generation Chevrolet Corvette. These consist of Black, Adrenaline Red, Gray, and Black with Suede inserts. Kalahari leather is only available on 2LT cars and higher. The Kalahari and Grep trims gain suede inserts on the 3LT.

2014-2019 Chevy Corvette Stingray Coupe Maintenance and Cost

Maintenance for the C7-generation Chevrolet Corvette is a fairly straightforward process. An oil and filter change needs to be conducted every 7,500 miles, but we would reduce that to 5,000 miles in a sports car like the Corvette, especially if it's going to be used in sub-zero temperatures or in dusty conditions. The passenger compartment air filter requires a change at 22,500-mile intervals while the air cleaner filter will need to be replaced every 37,500 miles. The rear axle fluid change should take place every 45,000 miles. New spark plugs are needed every 97,500 miles and a cooling system flush and refill should occur every 150,000 miles. As for the automatic transmissions, Chevrolet says that an oil change should take place every 100,000 miles, but we recommend a 60,000-mile interval instead. General annual service costs for the seventh-generation Chevrolet Corvette should cost in the region of $740.

Check Before You Buy

A handful of 2014-2019 Chevrolet Corvette Stingray coupe and convertible recalls were issued throughout the model's lifespan. The 2014 model year was subjected to five recalls. It was grouped in with a long list of other GM products for two airbag recalls that also affected the 2015 to 2017 models. 1,939 models were recalled for a rear shock absorber that could separate from the suspension due to an improper weld. 712 Corvettes had to be recalled for a faulty side-impact airbag that may cause injury to the passenger. Only 33 units had to be recalled for an electrical short circuit that could completely disable the airbags. 43 units - assembled in 2015 - were recalled for an improperly fastened toe link outer ball joint which can cause the part to separate from the chassis. A selection of 2017 units was recalled for a spontaneous loss of power steering assist due to a poor gear assembly.

Some of the problem codes that you might encounter in the C7-generation Chevrolet include:

  • Code P0011 means that the camshaft timing on bank one is over advanced. This is likely due to a poor camshaft actuator, VVT solenoid, timing chain, or circuit.
  • P0068 will show if there is an issue with the throttle body air flow's performance and could likely be due to an air leak in the mass airflow and throttle body or an air flow restriction in the system.
  • If your ambient air temperature sensor circuit has failed, you will see the P0700 fault code. If this is the case, you may have a defective sensor or electrical connection.

Chevrolet Corvette C7 Common Problems

Cracked And Warped Wheels

A cracking wheel problem on the 7th-Gen Chevrolet Corvette Grand Sport coupe and convertible appears to be such a serious issue that two class-action lawsuits were filed. Unfortunately, the material used for the Corvette's alloy wheels is susceptible to cracking after a few rounds over potholes and other obstacles. Once cracks start to appear, you'll notice that the tire's air will deplete faster than expected. You can avoid this issue by not opting for the Grand Sport model or fitting a set of aftermarket forged alloy wheels - which is a costly option. Slight cracks in an alloy wheel can be repaired, but if the crack is too deep, it would be better to consider replacing the wheel.

Mileage: C7 Grand Sport owners note that the wheels start to crack depending on the surface that is frequented, rather than mileage.

Cost: A new front alloy wheel for the Grand Sport costs $520 while the rear is a bit more expensive at $800.

How to spot: Rapidly depleting air from the tires likely means your alloy wheels have suffered cracks or have been warped.

Infotainment Screen Crashes

Some C7 Corvette Stingray and Grand Sport models may suffer from an infotainment touchscreen and radio problem that might see it randomly flicker or black out and become unresponsive. Considering that some of the Corvette's functions can only be accessed via this interface, it can be a bit of a hassle for owners. It is understood that the unit itself isn't to blame for this flaw, but rather the wiring, which is a relief because that results in a much cheaper repair. With some age and driving, the HMI module wiring may wear out and loosen its connection to the screen, which is what creates the glitches. You'll have to get this system rewired if this is the case.

Mileage: Infotainment glitches can occur at any mileage.

Cost: Excluding labor, a new HMI module wire should cost $150.

How to spot: If your infotainment screen is flickering or blacking out, your HMI module connection may be worn or loose.

LT1 6.2-liter V8 Common Problems

The LT1 takes the Corvette nameplate into the modern world of variable valve timing and direct injection, but with these innovations, some C7 Corvette Stingray engine problems did present themselves. With the direct injection system, the powertrain's biggest weakness is carbon build-up on the intake valves, which can set in at the 80,000-mile mark. You'll know that this is becoming an issue once you notice poor idling and a reduction in overall performance. The only way to solve this is by walnut blasting the intake valves. One means of postponing this is by installing an oil catch can.

The LT1 is also subject to lifters collapsing and bent pushrods. This particular issue is due to the cylinder deactivation system, which deactivates half of the cylinder to conserve fuel. It does this by deactivating the camshafts using a lifter system which can deteriorate and put extra pressure on the pushrods. This will result in several performance-related issues. In some cases, it is advised that you disable Active Fuel Management to prevent this because repairs come at a significant cost seeing that the engine will have to be taken apart. If this has occurred in your powertrain, you will notice a significant reduction in engine performance.

Before purchasing a used LT1-powered Corvette, you also need to ensure that the car was broken in in the correct way, as this has a significant effect on its longevity. Cars fitted with the dry sump need their first oil and filter change to occur at 500 miles.

Less prevalent but still noteworthy issues with the LT1 include fuel injectors and pumps failing to keep up with fuel demand, which will bring up the P100D fault code. This is because of the high pressure of the direct fuel injection system. Both of these parts are placed under heavy stress and can fail after extended use. In this case, they will have to be replaced. You'll know this is the case when misfiring, inconsistent acceleration, or poor engine performance is prevalent. You may also struggle with an intake manifold gasket prone to air or vacuum leaks. This will affect your idling, acceleration, and overall powertrain performance.

Mileage: Carbon build-up on the LT1 starts to appear at the 80,000-mile mark, collapsing lifters and bent pushrods are dependent on how frequently your cylinder deactivation system is running. Issues with the fuel injectors, pumps, and intake manifold gasket are likely to occur after 150,000 miles.

Cost: Walnut blasting the intake valves can cost in the region of $1,000. Repairing collapsed lifters can cost up to $2,500 while new pushrods can cost up to $3,000. Both of these costs include labor. A new set of fuel injectors for the LT1 will set you back by $920. A new fuel pump is $443, and a new intake manifold gasket is $4. All of these prices exclude the cost of labor.

How to spot: Carbon build-up will result in poor idling and a reduction in overall performance. A big dip in performance likely points to collapsed lifters and bent pushrods.

Automatic Transmission Shudders And Vibrations

There is a notorious Corvette transmission problem for the C7 generation. The eight-speed automatic transmission was another big step forward for the Corvette nameplate, but unfortunately, it is plagued with noticeable shuddering and vibrations when shifting and means poor drivability at around 20,000 miles. You'll usually notice these characteristics between first and second gear. According to a service bulletin from General Motors, this is likely due to an issue with the transmission fluid. A drain and flush should resolve the problem, but if not, you may have to replace the entire torque converter.

Mileage: Issues with the automatic transmission can present themselves as soon as 20,000 miles.

Cost: A transmission oil change is relatively inexpensive at $160. Replacing the torque converter can set you back by as much as $1,200.

How to spot: Shuddering or harsh vibrations when shifting between first and second gear means that there is an issue with your torque converter.

Less Common Problems And Problem-Free Areas

Less noteworthy issues that you may encounter with the C7-generation Chevrolet Corvette Stingray and Grand Sport coupe and cabriolet include rattling from the front of the suspension when taking sharp turns, and bubbles that form along the surface of the car's body paint. Problems with the air conditioning in the Corvette Stingray Seventh-Generation are highly unlikely.

Which One To Avoid

2014 to 2017 model years of the C7 Corvette should be overlooked because these were subject to the most recalls. The Grand Sport trim in particular may be a more appealing car, but given that the alloy wheels are prone to cracking fairly easily, it may be best to give it a pass unless you are okay with fitting a set of stronger aftermarket wheels. As is the case with every sports car, it is advisable that you avoid examples that have been fitted with mods.

Which One To Buy

Apart from the issue with the alloy wheels, the 2018 or the 2019 Grand Sport is still a more appealing choice than the Stingray because of the amount of additional kit you get and the fact that it was not subject to any recalls. It's a more viable option than the early Stingrays with the Z51 package because they are also considered to be more iconic. Either the 2LT or 3LT should suit your needs, depending on what you are looking for. Models that were specified with the 1LT may feel a bit too basic for your liking. Deciding between the coupe and convertible is also dependent on your preference. As for transmissions, the eight-speed automatic may be appealing for those who are looking to daily drive their Corvette, but it is not as refined as the seven-speed manual.

7th Gen Chevrolet Corvette Stingray (C7) Verdict

The C7 Chevrolet Corvette is the most advanced iteration of the car's front-engined heritage. Despite not being a fully-fledged flagship performance model, there is still loads of fun to be had from behind the wheel. It still struggles to leave behind its reputation for poor interior quality, but compared to previous-generation models it is still an improvement. In terms of design, it takes on a more aggressive approach which some enthusiasts may appreciate. The LT1 is not quite as dependable as previous iterations of the small-block V8s, but if you can deal with the carbon build-up from the direct injection system by installing a catch can and find a way to bypass the cylinder deactivation, there is no reason why it should be too problematic in the long run.
