| Description of the problem | 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.

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 |
