Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Jetta 4-cyl Diesel

  • 11,860 miles


After filling up our Jetta tdi with diesel gas we left the station and the car's glow plug light came on about 3 miles down the road. I pulled over to check with the manual to find out what to do. I said to take the car to the dealer as soon as possible. When trying to restart the car the check engine light also came on and it took several attempts to restart the car. I pulled back onto the highway and my car would not accelerate over 40 mph and felt very sluggish. I quickly pulled into the nearest turn out and called for a tow truck. The car was towed to the dealer the following day as it was a new 2014 with 11,000 miles. I was called by the dealer and told the gas we put in the car was "contaminated" and the entire fuel system would have to be replaced. Our gas receipt show that we put diesel gas into the car. We went back to the gas station (chevron) and spoke with the manager. He stated that they did not have complaints about their gas from other customers.

Jetta 4-cyl Diesel

  • 1,985 miles
Ref: NHTSA action number PE10034. Regarding my 2014 Jetta tdi (diesel): Fuel tank was approximately 3/4 full. Filled remainder (approx. 1/4 tank, 3.5 gallons) with ulsd auto diesel fuel at a service station in portage county, oh. I noticed an almost immediate loss of approx. 4 mpg in fuel economy. After researching the issue on various Volkswagen tdi/diesel internet discussion forums (in addition to various Chevy and/or Ford diesel pickup truck internet discussion forums), the symptoms seemed to coincide with damage to the Bosch CP4 hpfp (high-pressure fuel pump). Symptoms include: -- loss of fuel economy. -- minor hesitation even on smooth, level roads that gets worse over time. -- presence of metal "flakes" or "shavings" in the fuel filter canister and other parts of the fuel delivery/return system. -- I drove the vehicle to the point of purchase (an official Volkswagen dealer), and requested they provide me with a visual inspection of the fuel filter and fuel filter canister. This inspection confirmed the presence of naked-eye-visible contaminating particles (suspected to be aluminum metal "flakes" or "shavings") in the fuel filter canister, and possibly other parts of the fuel delivery/return system. Due to the fuel delivery/return system design, these metal "flakes" or "shavings" can be re-introduced into the high pressure fuel pump without being trapped by the fuel filter, causing further damage to the hpfp and cascading contamination (generation of additional metal "flakes" or "shavings"). once fuel flow through the hpfp, fuel accumulator rail, and injectors becomes sufficiently restricted by contaminants, the hpfp can fail catastrophically, resulting in a sudden loss of engine power. This, in turn, can lead to a loss of vehicle control due to the absence of power steering. Case opened with VW customer care.

Jetta 4-cyl Diesel

  • 200 miles
From a complete stop, pushed the accelerator and nothing happened for 4 to 5 seconds. Tried again and the car slowly rolled forward only to have the accelerator not work again almost causing the car to be T-boned in an intersection. This happened several time that day. Foot was no where near the brake pedal. This has occurred several times since and 5-24-14 happened again almost causing us to get hit crossing traffic. 2 dealerships have yet to duplicate it and will go in again 6-3. this car is dangerous to drive, so much it has sat twice a week at a time. It is not a turbo or diesel response. There is a huge problem with this car.
