Owner reports
Selected complaints filed with NHTSA by 2002 Volkswagen Jetta owners, lightly cleaned up (personal details are redacted by NHTSA).
We were traveling 70 MPH on a highway in our 2002 Volkswagen Jetta wagon (gls 1.8t) when, without warning, an loud "poof" sound was heard, the car lost all power, and we smelled burning plastic. The car regained power, then a second "poof" sound was heard, and the power flickered in the car, at which point the car began filling with smoke. We rolled down the windows, pulled over to the shoulder, and evacuated the vehicle. We pulled out what belongings we could, but retreated from the car once flames appeared on the driver's side interior. Approximately 1 minute later, the entire car was engulfed in flames and was a total loss. We are thankful to have escaped with our lives. Here are the specifics of our vehicle: model:Jetta trim:gls body style:4 door wagon engine:1.8l i4 20v mpfi dohc turbo transmission:automatic.
Oil light is blinking, I was told by several mechanics that jettas as well as volkswagens in general are known for having terrible sludge issues. I took the car to the dealership, they charged me over $150 to diagnose my car, after diagnosing it they said that the engine needs new oil bearings due to sludge issues, they said that the oils pressure is fluctuating and that soon my engine will blow up, they said that this was not covered under similar recalls that they've had on other models of theirs and that to fix my problem I would need a new engine which would cost me over seven thousand dollars. It seems to me that this is a very well known problem for vw, they've known about it for years but just like the problem they're having right now with the software, they've kept this quiet.

On September 30th, I took my Jetta in to valenti Volkswagen to have a new and updated ECU installed. The unit was in stock, I received a call from rick in parts and made an appointment to come in that day to have it put it. When I arrived, I was told by the technician the ECU in my car had to be sent to Volkswagen to be reprogrammed and that I had to get a rental car while the ECU was out. I got a call from service on October 12th letting me know my car was ready to be picked up. When I arrived, I was told my ECU was still at Volkswagen being reprogrammed. The service manager was able to get a new and updated ECU in the mean time. I don''t know why they just didn''t install the ECU they had in stock on September 30th. I had to pay a total of 119.88 to enterprise for the rental vehicle. I''ve called in to Volkswagen care numerous times regarding this complaint and nothing was resolved. …
While driving in the afternoon, my vehicle suddenly lost power and acceleration capability with the "check engine" light coming on and blinking. I took it to the dealer immediately. I am informed my 2002 vw Jetta 1.8t has "3 faulty coils." the failure was sudden and without warning. I maintain my car according to vw specs. In 02/2003 vw acknowledged a problem with this in over 530,000 2001 to early 2003 vehicles. I feel the failure was premature (as to what could be typically expected of an engine/vehicle for reliability), and a danger. Obviously the fact that it has remanifested in such a short period of time shows that it was not properly addressed with the original fix only 2 years ago. My vehicle was unable to adequately maintain itself within the flow of traffic. I was lucky to get to the 'slow lane' without incident. …
In April 2006 we purchased a 2002 vw Jetta from a private party. The car had 65,000 miles. She was the original owner of the car and had taken meticulous care of the car. We have all the service records dating back to it's original purchase. It had been in for all scheduled tuneups. Vw offers a 60,000 mile or 5 year warranty on the drive train. In November 2006 the radiator warning appeared on the dash. We took it in to the dealership and they claimed the radiator and transmission were mixing and caused significant damage to he transmission. Estimated cost of replacing the transmission $5,890. The dealership mechanic never stated what caused the mixing fluids and would not speculate. We took the car to our local mechanic. He was able to isolated the problem within 20 minutes. The transmission cooler is leaking allowing the two fluids to co-mingle. …
I have two problems, one with temperature coolant sign. Many Jetta's have this problem, it occurs every time I turn on the car, sign always comes on. This causes signals and computer programs in the car to be confused, and is always a dangerous light because I never know if there is something wrong with my car's coolant or radiator. I have replaced this part about two times through a mechanic shop with a vw part twice. Still is a failure, and I read most jettas have this problem and it is ridiculous that vw can not fix this expensive part for its customers. Also I had a problem with my alternator one day ago. My vehicle was forced to stall on the middle of the highway causing me almost to get into an accident. For some reason my car lost all its power, battery was only one or two weeks old, and now my alternator died. …
First issue, the engine is burning oil. I've noticed that my car engine started burning oil when it had about 50,000 miles on it. It took me almost two years to prove to the vw dealership mechanics that the engine is burning oil. At 73,000 miles the vw dealership mechanics rebuilt the engine. My oil consumption normalized. Now, at around 115,000 miles, I've noticed that the engine started burning oil again. 1,800 miles after an oil change, jiffy lube mechanic had to add 2.5qt of oil. Shouldn't the engine last at least 100,000 miles after rebuild? It seems that this engine only lasts 45,000 miles. This feels like a major defect and vw has to recall the engine. Second issue, my car is only 8 years old but it's on its third transmission. I had to replace transmission at 32,000 miles and again at 73,000 miles. …
