2021 Mercedes-AMG CLS 53 Safety and Reliability

Mercedes-AMG CLS 53 Reliability Rating

2021 AMG CLS 53 Safety

Both the NHTSA and the IIHS have yet to evaluate the CLS lineup, so no crash rating exists for this model. However, the Mercedes-Benz E-Class attained only Good crashworthiness from the IIHS in 2020 and a Top Safety Pick+ award in 2019; being mechanically identical to the CLS, the E-Class serves as a good indication of how the CLS will perform in a crash test.

2021 AMG CLS 53 Key Safety Features

A suite of seven airbags offer nine-way protection in the unfortunate event of an accident. The suite includes a driver's knee airbag, the usual dual front airbags, and curtain airbags for all outboard seating positions. To avoid the chances of hitting anything in the first place, the Merc comes with electronic stability control, a surround-view camera system, driver attention assist, blind-spot assist, rear cross-traffic alert, and front/rear parking sensors. A dashcam is a newly added option this year, along with previously available extras like adaptive cruise control, evasive steering assist, adaptive high beams, active lane-keep assist, and active lane-change assist. Most of the optional safety features can be equipped as part of a single package.

2021 AMG CLS 53 Reliability

The 2021 Mercedes-AMG CLS 53 had not yet been recalled for any serious issues at the time of writing, although it was involved in two recalls last year. Both of these were related to the eCall system which could send out an inaccurate location following an accident. This could, of course, prove dangerous if first responders are delayed.

Mercedes' standard four-year/50,000-mile warranty applies and also covers the powertrain, while roadside assistance is provided for the same period/mileage.
