Selected complaints filed with NHTSA by 2015 Volkswagen Jetta owners, lightly cleaned up (personal details are redacted by NHTSA).
I purchased a 2015 Volkswagen Jetta from North Coast Auto Mall on March 19, 2023 and the following day several issues went wrong with the vehicle like: The car reeked of gasoline, oil and engine lights came on, driver side head light blew out. Also, I was told that the car had an inspection, come to find out they didn't do an inspection by North Coast Service manager, so they lied. Also, the reason for the gasoline smell is because the vehicle needs a fuel rack, oil pan, oil pressure switch, and a new headlight. Too many things are going wrong with this car in such a short period of time. It took North Coast two weeks to take my vehicle and they didn't want to give me a loaner car. Also, they have had my vehicle since March 28, 2023 and refuse to disclose of the reconditioning shop of my vehicle. …
I've been experiencing intermittent start failures with my 2015 Volkswagen Jetta. The issue typically occurs after driving short distances, turning off the engine, and attempting to restart the vehicle within 15-45 minutes. The dashboard lights stay on, but the engine fails to crank. After extended wait times (1-3 hours or more), it will sometimes start again. A diagnostic scanner showed DTC IM 00, indicating an immobilizer system malfunction, meaning the car isn't recognizing the key properly. I've tested both keys and various conditions (locked/unlocked, sun/shade, full/low gas tank), and the issue continues to be unpredictable. When the car was towed to the dealership, they were unable to replicate the problem since it started by the time they checked it, and they were unwilling to investigate the immobilizer issue without charging me for a wide range of unrelated tests. …
Car cut off twice while driving and could not be restarted for 14 - 25 minutes. This happened while driving. I took it to both an independent mechanic and a vw dealer, bit they were unable to diagnose the issue. Also, after being driven, intermittently the car will not start for 15 - 25 min. Other drivers are also having this issue.

I am writing to advise you of a potential safety issue with the design of the Volkswagen Jetta. I own a 2015 Jetta. After a heavy rain, and usually after passing through standing water, the car loses power and stalls. This has happened on three occasions recently. I first took the car to my own mechanic, an experienced technician with a major repair franchise. He was unable to pinpoint the problem. When the problem recurred, I took it back and he again tested it but was unable to say for sure what the problem was. However, he noted that there was an air intake in the front end that might have taken in water and caused the issue. I then took the car to the dealership (burlington Volkswagen) and they were also unable to diagnose the problem. However, the mechanic there also indicated that it might be due to water entering the air intake in the front end. …

I started to smell of gasoline in my car while driving it. Called vw group of America costumer service number who suggested I take the car to a dealer for inspection. After inspecting the car for two (2) days, the dealer, south motors vw, verbally reported the problem cause was a fuel leak at the injection system: fuel rail. Just as described in the 15V028000 recall. Vw group of America has declined my request to accept this failure as part of the reference recall under the allegation that the vehicle identification number (VIN) is not part of the recall and the vehicle has more than 36,000 miles. (actual mileage: 47,500). I understand the recall is VIN selective, but it's not out of coincidence that my car was assembled in puebla, Mexico; the manufacturing year falls in the recall category and that the supplier of the defective part is benteler de Mexico in puebla, Mexico.
Acceleration falls flat unexpectedly off the line. Ever since the re-program of the tdi affected vehicles the car will accelerate quickly at first when given good throttle (70%+), but then all of a sudden at 30-40mph or so it will totally fall flat all of a sudden, and dangerously so. It just completely loses power, and being a diesel, it decelerates fairly quickly. I have had numerous times where it's happened, so much so, I know better than to even try anymore. When pulling out in chicago traffic this can definitely bite you in the rear. It almost seems worse in 'sport' mode also. I sold these cars for almost 8yrs and I never drove one that acted like this. I think they need new programs, the current ones are not only weak, but dangerous.
About three weeks ago with 16K miles I called vw and indicated that my Jetta smelled like diesel. I was told it was probably just an overfilled fuel tank. It turned out to be a leaky high pressure fuel pump. On the 2015 Jetta, this is located on the top of the engine. This literally means that fuel was leaking directly onto the hot engine and exhaust. The leaking fuel eventually ate through radiator lines and caused a complete loss of coolant. Obviously leaky fuel + hot engine / exhaust = fire risk. Not to mention the coolant loss stranded my family on the side of the road. The loss of coolant happened at city speeds and stranded my family.
