Example complaints

Electrical system: “In may 2019 I purchased a certified pre-owned 2015 Porsche carrera gts and had it for 11 months before it caught on fire while driving it. A forensic investigation revealed that the cause of the fire was the electrical board located on the inside of the cabin near the right rear tire. On the day of the incident, after driving the car less than 15 miles from my home to a nearby property I noticed the car was smoking as I pulled into the driveway. I parked the vehicle and found that there was a small fire in the engine compartment. …”

NHTSA complaint #11322421, filed 2020-04, 42,000 miles

Engine: “The PCM unit which controls the cars computers keeps shutting on and off saying do not drive. Get service ….. This has happened on many cars and there was a class action suit regarding a recall. It is now closed and I was never notified.”

NHTSA complaint #11622211, filed 2024-10

Other or unknown: “Spoiler lift spring brackets on both sides are broken allowing the springs to get in the way of the normal performance of the spoiler. This could impede the deployment of the spoiler or the successful retraction of the spoiler, creating a reduction in downforce (grip) or creating a safety hazard of a non-fully retracted spoiler. This was identified by a third-party repair shop during maintenance work. In doing further research online I have determined that this is an extremely common issue on this model generation (991.1) that Porsche will not address.”
