My jetta stalls without warning when the gas gauge is at a quarter of a tank or less. No engine check light or any other any other device comes on to warn me it is going to stall. My speed does not matter. It happens at freeway speeds or around town. It does not occur if the gas gauge shows more than 1/4 of a tank of fuel. I do not know if it is an electrical problem, a fuel propulsion problem or an engine problem. From reading volkswagon forums, this is a very common problem with volkswagons of different years, including the new Tiguans. I'm sure there have been many fatalities as a result of this defect. I am surprised volkswagon has not been forced to repair this dangerous, life threatening problem before now! Maybe, a class action law suit involving products liability, merchantability, and fitness for a particular use would benefit not only owners, but the general public at large. …
This is in regard to tiptronic transmission failure at 77,000 miles. After the vehicle was fully paid off and 17K miles after warranty had expired. While I was driving vehicle would stay in 1st and 2nd gear and give a big jolt when going into 3rd and 4th while still cold, only after engine would heat up without any stops would it perform sub par. Previous to this I had have no complaints. Dealer quoted $5600 to rebuild transmission and independent shop $2500. I was informed I had a worn clutch and in 2008 I rebuild the transmission and continued having the same issue. After thousands of dollars spent on this vehicle on April 12 of 2012 I sent it the junkyard. I will follow up and send more hard copies documents to NHTSA as I have my entire service records from 2003 - 2012 to submit. …

I have owned a Volkswagen Jetta (turbo - 2003) and have had one horrible problem after another. Without fail, I have taken my vehicle in for random mechanical repairs every few months since purchasing the vehicle. I found out the car was manufactured in Mexico and that vw was aware of how bad their car's manufactured in Mexico were. If that is the case, how can so many car owners with so many mechanical issues continue to sell in this country? I would like to report vw for lackluster performance and for continuing manufacture in an area well known for its below average standards and for continuing to bleed the consumer when it is fully aware of the issue.
The car was parked for two days without being driven. While it was parked, neighbors ran over to report it was smoking under the hood. We saw that there were flames coming out from underneath the front of the car. Fire department came, but fire had already extinguished itself. Fire department disconnected the battery ground and said the wires going to the cooling fan had set on fire. All of this was spontaneous. Engine was not on.
The oil pump quit, causing the oil pressure lamp to come on. The vehicle is still under warranty, but since I cannot produce all of the receipts for oil changes since I purchased the vehicle, they will not cover the warranty. The dealer says that the failure was due to oil sludge. I was not informed that I had to keep receipts for oil changes durring the lifetime of the vehicle.

2003 Volkswagen Jetta caught on fire while driving. A vehicle following my sons car on a major interstate (my son was out of state returning home) noticed smoke coming from under the car and blow horn and flickered lights.

The Jetta never lost power and when he pulled off the road and he had to turn the ignition off. The Jetta was smoking and the fire started immediately and with in minutes full flames. There was a loud boom and it came from the front of the Jetta. The fire department could not get the fire out and had to break through the hood. The whole front (engine area) was burned. …
Bought a Volkswagen Jetta gls in 2003. Several things have had to be replaced. For example the glove box cover, wheel bearing. My mechanic told me that on most newer vehicles that wheel bearings do not require maintenance. My car has 74,000 miles. Last week I was driving and my malfunction indicator light started flashing and the car if going over 30 MPH cut out. There was a rotten egg smell. It immediately went to the dealership and they said the catalytic converter and 2 coils were faulty. They replaced the catalytic converter and ignition coils for cylinders 1&3 and cleared fault codes. The catalytic converter was replaced under warranty. But said Volkswagen feels the ignition coils are a regular maintenance issue. I have done some research and am finding that Volkswagen has numerous complaints on the coils. …
