What owners say about the engine
Verbatim from NHTSA complaints, newest first
“I remember having my keys in my hand and my car was slowly reversing out the driveway. I panicked, i was stomping on my brakes for a while jerking back and it took me about 2 minutes to finally get the key back in and try to put in park again. I went to a shop the following weekend because all the jerking and jabbing to get my key back in seems to have caused my ignition switch to misfire or whatever the word he (mechanic) used, so now i cannot take my key out like a regular person, I have to flick my key a certain way out anytime i want to turn my car off.(even mechanics have a hard time taking it out. I was also given a qr code to scan and was brought the this exact recall of the situation with my car. I now have my engine light on and [XXX] gave me the fault code for my map sensor. I’m not sure if the two are related but this was following the incident.”

The engine and power steering had failed. The glow plug warning light was illuminated. The vehicle was towed to a dealer. The contact was informed that the failure was due to the high-pressure fuel pump which sent metal shards through the fuel line. The manufacturer was made aware of the failure. The failure mileage was approximately 115,000.”
“My DPF system failed after my warranty ran out, about 128,000mi. and VW charged me $3000 to replace the DPF, then two days later the Nox Catalyst failed and they wanted another $2500 out of me. I tried the regen like the manual says, and the car went in limp mode 75 miles from my house in the middle of the highway. The car is not safe to drive, and they would not tell me if replacing the Nox catalyst will fix my problem, or just reveal another multi thousand dollar problem. The car is parked for the past 6 months and is not drivable.”
