2016 Porsche Cayenne Complaints

The contact owns a 2016 Porsche Cayenne. The contact stated that moisture was entering the headlights on both sides of the vehicle. Over time, the condensation in the passenger’s side headlight was burned out with a message on the instrument panel. The manufacturer was notified of the failure and referred the contact to the dealer for a diagnostic test. The dealer gave the contact an estimate without a diagnostic test. The manufacturer was called and informed that they would provide a nominal portion of the repair cost. The vehicle was not repaired. The failure mileage was approximately 65,000. The contact stated that they took their vehicle to a couple dealerships and mechanics before the issue was diagnosed as a design flaw. Therefore, simply changing the headlights out would not fix the problem.

The contact owns a 2016 Porsche Cayenne. The contact stated that while driving at various speeds, the vehicle would hesitate to accelerate while depressing the accelerator pedal. The contact stated that the failure was intermittent. On one occasion while driving, the failure occurred and nearly cause the vehicle to be rear ended by a vehicle speeding from behind. The vehicle was taken to the local dealer on multiple occasions however, the mechanic was unable to determine the cause of the failure before performing a software update to the accelerator pedal which appeared to correct the failure. The manufacturer was not notified of the failure. The approximate failure mileage was 40,000.

the driver receives a warning light in the instrument panel left tail light is defective, and then right tail light defective. Some times tail light works and does not when car is in cold weather Was told that both tail lights were defective and would have to be replaced at a cost of $3400.00 . Found an after sale Porsche publication saying that it affected 2015-2018 Porsche Cayenne. Dealer told me that it is no longer covered since my warranty is not in effect anymore. However this is a safety issue not a warranty issue. Have paperwork stating that Porsche knows the tail lights are defective. Since I live in Florida they have been working fine. But as soon as the car is in colder climates this starts to happen

When slowing almost to a stop, and then need to accelerate, such as slowing for a yield sign, then trying to merge, vehicle is non responsive to throttle input for at least a second, or more. This has put me and others at risk because I assume I'm going to be able to accelerate when pull into traffic and am not able to. The dealer has had the vehicle but was unable to reproduce. It does not always do it, there's some combination of engine, drivetrain or fuel management it's in that does this. I have disabled start/stop mode. There are no system messages or OBD errors. The dealer has said that others have experienced this and the manufacturer has told them it's "normal". It's a safety problem and I'm seeking help in getting the manufacturer to fix it. Note, I sent the attached letter to manufacturer and did not receive a reply. I called their customer support line around Sept 20th and they did not offer any escalation or other action to address other than writing to their email...

OUR TURN SIGNAL SOUND IS SO LOW THAT WE DO NOT REALIZE THAT THE SIGNAL HAS REMAINED ON SINCE OUR LAST TURN. IT HAS CAUSED ONCOMING TRAFFIC TO STOP UNNECESSARILY AND FOLLOWING TRAFFIC TO PASS INSIDE ASSUMING WE WERE TURNING LEFT. BOTH SITUATIONS HAVE CAUSED NEAR ACCIDENTS.
