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.

2012 Volkswagen Jetta Owner Comments

I purchased my 2012 Volkswagen Jetta approx October 31, 2011. Within the first 3-4 months the car computer system locked up while I was driving. (I was unable to put down the windows, the A/C stop working, engine lights lid up on the dashboard) so I drove it straight to the dealership and they immediately apologized and kept the car for several days to correct the defect. In 2013 the steering lock went bad while driving and we couldn't turn the car off. This happened at 6:45pm after the dealership closed. So the car continued running in front of my house from 6:45pm to 7:30am when the dealership opened. I explained to the dealership how frustrating, physically, and mentally draining that night was. We couldn't park the car in a garage and risk the gases getting into the home so we left it in front the house and had to stay up all night and watch it so no one would steal it. They diagnosed it as a bad steering column. The car sometimes accelerate fast on its on when you attempt to use the cruise control. Now currently the sterling lock is gone bad on the car again. I have contacted Volkswagen and the dealership several times about this part/issue this year and they told me the car is out of warranty and I would have to pay for the repair. A steering column going bad in a car every year is not normal. My problem is paying for this faulty, defective dangerous car. I have invoice and repair invoice on this car dating back to the first few months of owning it. Volkswagen is on a major coverup to avoid a massive recall of several of the vehicles they knowingly are putting drivers at risk.

Car ceased to continue acceleration while in motion. Dealer assessment concluded particulates in diesel fuel line caused failure to fuel pump and related components. Dealer service department advised that particulates likely originated from diesel fuel storage tanks at gas station. Vehicle was still covered under manufacturer's 50K power train warranty and fuel pump and related parts were replaced at no charge.

Jetta 4-cyl Diesel

Accelerating up from a stop sign vehicle would not shift. Pushed on accelerator and vehicle lost all power and went into limp mode. Could have resulted in accident if I had been merging on a very busy highway. Had vehicle towed to dealership and they found a engine code but are unable to duplicate and want to return vehicle back to me without resolving defect.

Midnight, driving back from a friends house. My 16 month old (or rather new) Jetta SE 2012, shakes up when I turn on ignition. I give it 2-3 seconds to calm down. It doesn't. instead, the epc light goes on. Then the check engine light. Hmm... weird. Those weren't on like 2 hours back, or ever infact. Being the smart techie that I am, I try the highly technical solution to any problem that I don't quite understand - I try to turn it off and on again. The same god awful shaking and stuttering. But no epc light. I think to myself, maybe this is just a transient thing. Try to pull out of the parking space, and there it is... the [xxx] epc and check engine light. But my home's only a mile away, maybe things get better on the way there. You know, its a new car (bought 16 months back, brand new, and has ~7600 miles on it). But no, as I try to "drive" the piece of [xxx], it starts shaking more violently when I get to 25 miles and hour. So, I pull over, and a quick google search tells me to stay below 20 mph and get it to a dealer asap. So I get the car towed, and the next day the dealer tells me its a faulty ignition coil that has been replaced and tested and things should just work. But I'm scared to get in that car again. What if this would've happened farther away from my house. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The 2012 VW Jetta 2.5 has a vehicle defect in which upon a need for acceleration, the car stalls out. While the engine continues to run; the vehicle does not move. This vehicle has failed on three separate occasions nearly causing accidents each time. VW refuses to acknowledge the defect even though other VW owners have documented this defect in a variety of websites regarding the product.

Volks 2012 Jetta tdi. At highway speed of approx 55-60 mph, with cruise control engaged, transmission seemed to come out of gear, engine revved and tachometer red-lined, vehicle began to slow, but obviously not loose power as evidenced by tachometer and high RPM's on engine. After tachometer red-lined, tachometer then began to drop and at about 5,000 RPM, transmission shifted a couple of times and then operation of vehicle was back to normal. Oddly, cruise did not have to be reset and seemed unaware of the event that had just occurred. Entire event occurred in the span of about 5 seconds. Took vehicle to dealer. Service documentation says "we scanned for faults and had a sporadic fault for gear shift control module. Performed test plan and found no problems. We cleared faults." Another service showed the error code with verbiage something to the effect of "lost communication with gear shift control module." Dealer would not replace gear shift control module and stated that if it happens again, return and they will replace. Clearly this is a safety issue, particularly when it occurs on a highway at highway speeds with congested highway traffic and clearly could have resulted in an accident.

New volks Jetta 2012. Purchased new from volks dealership with approx. 40 miles on vehicle at time of purchase. Since day one and continuing through today with 12,000 miles on odometer, transmission lurches and jerks, either slipping in and out of gear or seemingly not able to figure out which gear to be in. Usually occurs while trying to maintain a constant speed. For example, while in school zone with 20 mph speed limit, car will lurch, jerk and shudder, sometimes violently with the symptoms described above. Additionally, when coming to a stop at a stop light for instance two conditions frequently present. 1. after coming to a complete stop, transmission is still in the process of downshifting. In other words, once completely stopped, you can feel the transmission still shifting down through the last couple of gears. 2. after coming to a complete stop at a light, when attempting to accelerate, car is not in gear and requires depression of gas peddle before car will engage in first gear. All of the above are dangerous situations. Dealer continues to insist that transmission is "learning" my driving habits.

The failure recurred numerous times and became intermittent. The manufacturer was notified of the issue but offered no assistance to the contact. The vehicle had not been repaired. The failure and current mileages were 700.
