For the past nine years, my vehicle has recorded multiple safety issues (trunk not closing/breaking, check engine light, catalytic converter misfire, keyless electronic entry issues, glow bulb light, turn signal bulb light, windows not rolling up, leaking fluid on the passenger side, burning smell coming from the vents, electrical issues with the radio, sunroof intermittently not opening/closing and the key not turning the vehicle on. Over the past nine years, I have taken the vehicle to numerous Porsche dealerships per the federal mandate from Porsche USA / Porsche UK. To date, the Service Manager, Chris Sansbury and General Manager at Brian Harris Porsche, and Porsche USA, refuse to fix the vehicle. My vehicle is still under factory warranty. I am a person with multiple disabilities. The dealerships (Jim Ellis Porsche, Hennessy Porsche, Leith Porsche, Brian Harris Porsche) have charged me thousands of dollars. I have been extremely sick and desperately need your help. Please help me!

Front timing cover has large leak. Vehicle has 88,000 kms, always regularly serviced at Porsche dealership in vancouver. This is a very common issue with Porsche V8 engines and requires a fix in the amount of approx. $5000-8000, as the engine has to be taken out of vehicle. As my vehicle is out of warranty, this cost is prohibitive out of pocket, especially considering the vehicle is relatively new with low kms. Porsche should either do a recall for these engines or provide extended warranty up to 10 years for the leaks, considering it is way too common. There are lots of reports in rennlist, 6speedonline and other numerous forums regarding this.

Porsche diesel emission compliant fix: - Porsche was required to apply emission fix to 2014 Cayenne diesel - diesel emission settlement requirement is the emission fix "..will not result in any noticeable changes to the driving characteristics.." - in Jan 2018, emission fix was applied to 2014 Cayenne diesel - right after fix, the car showed 2-3 sec lag from the stop. At stop, when gas pedal is pressed, the car does not accelerate for 2-3 sec, then it "jumps" - in may, car was taken to Porsche dealership. Dealer stated that this lag is normal after fix, even though there was no such lag before fix - Porsche dealership installed latest software on the car in May. After that, lag decreased from 2-3sec to 2 sec. But the car still has abnormal lag - it feels unsafe to drive the car, when merging to roundabouts, when merging from the stop - a complaint was filed with Porsche cars of America. Requirement of no "... noticeable changes to the driving characteristics" was discussed. Porsche said that the performance is "as designed" - clearly, when car was purchased in 2014, there was no lag. That's when the car performed as designed. - emission fix noticeably changed car driving characteristics, it made the car feel unsafe. Pressing gas pedal from stop does not result in smooth power delivery, it is not clear if the car will drive or not for 2 sec

I was exiting the highway into a rest area, and at about 30-35mph the car's engine suddenly cut out. All the dashboard warning lights lit up, the power steering failed, and even with the brake to the floor the car would barely slow down. I put the car in park and restarted it and it drove normally. I'm now afraid to drive my brand new car, because if the engine cuts out in the middle of an intersection or turning left against traffic, I could be involved in a very serious crash. This is more than just an inconvenience, it is a very serious safety flaw! if I was making a left turn against traffic and my two year old niece was in her car seat in back, she would be directly impacted by the vehicle due to the fact that the car decided to stop working!

Same day I both car when I reached home... the right side turn signal light fell off and was hanging from the wire. I had to go back to the dealership twice to fix this problem because they didn't have anything in stock. After 200 miles on my car I started to hear a knocking sound between console panel and engine, when I went to the dealer first time they tried to convince me that it"S normal because there is similar sounds from some of other cars they have in stock. They didn't show me any other cars that has this sound when I was there. They stated that on their report that they do not know what the sound is, but it is on other cars as well. I told them that the same model car I test drove, did not have this sound, why would the same car have such a noise. There was no answer or response to this question. They just stated that they don"T know what this. I checked 2 other cars myself at the same dealership, one of which, the technician was present from same dealership. He said that the car we checked doesn't have any noise, but my car does. Service department manager told me to drive around to hear if noise gets louder then come back to dealership. The knocking sound on and off, got progressively louder. I went back to the dealership 3 times with the same problem but they still didn't know what was causing this and didn't want to do anything about it. My car also have a problem with the security alarm system, it goes off at any time of day or night and they did not try to rectify or resolve the issue. I also noticed from being at the dealership, that there's also a problem with security system alarm on many of the cars. Wheels paint constantly peeling off.
