What's wrong, in plain English: Engine problems range from stalling to fire. Cracks may develop on the surface of the engine cylinder bore.
What could happen: Cracks may cause engine damage and a stall or an oil leak, increasing the risk of a crash or fire.
The fix: Dealers will replace the engine, free of charge. Owner notification letters were mailed July 9, 2021. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AMB1.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 CAYENNE GTS.
- Book a repair at any authorized Porsche dealer. Quote NHTSA campaign 21V341000 (manufacturer code AMB1).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-767-7243.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

Dashboard leather is separating and was told this could affect the airbag deployment in the case of an accident. Porsche dealership is asking 10k outside of warranty to replace the dash. If it was just cosmetic I could deal with it, but now that it is a safety concern for my passenger I feel forced to overspend. Even a reduced amount would help but a whole…

Porsche dealers are notoriously recalcitra…

There was no starter noise indicating a weak battery. I had to have the car…

While coming to a stop the vehicle lurches around 1200 rpms as the rpms are falling. The vehicle appears to already be in 1st gear when this happens.
