   On the day of delivery of this Porsche Approved Certified Pre-Owned vehicle (purchased May 24, 2022, from Porsche Nashua, Nashua, NH), traction control and all-wheel-drive warnings appeared on the drive home from the dealership. The valve lift solenoid/actuator was replaced under warranty; the vehicle spent 7 days in the shop. Within four months (September 2022), the engine fault light returned and the engine had to be dropped for repair (fuel tank breather pipe replacement and DME reprogramming) — 13 more days in the shop. A certified vehicle should not suffer stability/drivetrain faults on the day of delivery.

   While driving 40 miles per hour a sudden explosion happened with no warning. Thought it was the engine due to the smoke coming out of rear of the vehicle but realized that engine was still on and steam was coming out. All coolant drained out of vehicle and on road. Vehicle was towed to a Porsche dealership in Duluth Ga. The coolant tank exploded causing minor body damage and sudden loss of all coolant. The dealer replaced the shattered coolant tank but found no cause as to why the pressure got so high to cause the tank to explode.

   The rear window seal is severely breaking apart, severely cracked and others are melting. This may affect condensation inside the vehicle and potentially be a safety hazard. Several reports on this problem can be seen at porsche forums. I believe this is a manufacturing defect and is a potential safety hazard on many porsche vehicles.

   My air conditioner/heater fan does not come on after car has been sitting for a few days in a humid climate. This problem is documented with a temporary fix on the static.nhsta.gov site. https://static.nhtsa.gov/odi/tsbs/2021/MC-10186302-0001.pdf The problem is it happens to me every week or so. There is no permanent fix. This is a safety issue because without the fan motor the defroster doesn't work and the windows can fog up creating a dangerous situation.
