30,000 vehicles might not typically strike us (or you) as a particularly large recall. Not when some campaigns number in the hundreds of thousands or even the millions. But the proportion of this one has us sitting up and taking notice.

Porsche has issued a recall notice for certain examples of the Panamera. 33,206 of them, to be precise, from the 2010 to 2016 model years. Which is a pretty large number considering that it only sold 42,783 of them during those calendar years (which, mind you, don't directly translate to model years).

The recall includes close to the entire array of Panamera variants offered during those years, including base, S, 4, 4S, GTS, Turbo, Turbo S, and S E-Hybrid models, as well as long-wheelbase Executive, special Platinum and Exclusive Series editions, and diesel models. So chances are pretty strong that if you have a first-generation Panamera, yours will need to be brought in.

Porsche replaced the first-generation Panamera with an all-new model for 2017, and sales have responded in kind. Last year the German sports-car manufacturer sold over 8,000 of them in the United States alone, reaching a new high-water mark for the model line.

Those first-gen models, though, have apparently had a problem with water leaking into the A/C blower control unit. The moisture could cause the electronics to short-circuit, which in turn could spark a fire. So Porsche is instructing its dealership technicians to add a relay harness and reseal the entire blower control unit to keep water from getting in. In the meantime, it's advising owners to park their Panameras outside, lest a potential fire spread to, say, the entire house and engulf everyone and everything inside.
