general problems of the 2012 Volkswagen Jetta

When starting my 2012 vw Jetta, the abs light, brake light, passenger air bag light come on on the dashboard along with a long beeping sound. The sound eventually stops but the lights stay on. Vehicle is trying to run through diagnostics upon starting (vehicle is stationary but lights remain on while driving) when these lights come on. The brakes on the vehicle are fine and do not need to be serviced per mechanic and vw. Personal mechanic along with authorized vw service pulled the following codes: 01130 abs operation not a plausible signal, 01317 control module, 01285 cluster, 01486 system function test failure. Vehicle mileage is approximately 63k. Abs module failure has been a known issue with these vehicles and there are tbs's and technical tips for troubleshooting as well as a recall for 2009-2010 Jetta's. Properly maintained vehicles should not require abs module replacements at 63k miles. Was also told that by authorized vw service that this vehicle also has a leaky vacuum pump. Total cost of repairs: $2,636 for replacement of abs module plus tax and $1,036 plus tax for replacement of the vacuum pump. Neither of these parts should need to be replaced on this 2012 vw Jetta with 63k miles. This is absurd. There should be a recall on these parts because, especially with the abs module, they are clearly defective. You will find many consumer complaints about the abs module on the web for this vehicle.

Horn only occasionally works when honking and/or locking car, which increases the risk of a crash since I can’t always use my horn to alert other drivers of presence. One front headlight only occasionally works (lightbulb is not the issue), which increases the risk of a crash since other drivers may not be able to see me as well & I am not able to see the road as well in the dark. Cruise control does not work at all, which increases risk of speeding and therefore increases risk of crash. Dealer has inspected horn/headlight issue but could not determine cause. No warning signs. Issues first appeared a couple years ago.

I've noticed that my check engine light comes on and off, it's the map sensor. It has been replaced several times and everything has been fully cleaned, check engine light still comes on. My car also seems to go into limp mode while driving. I'll make a turn, and all of a sudden the car will not want to move at all, ill switch it to triptronic and it doesn't want to down shift or up shift. I have to pull over on the side of the road. Turn the car off then back on. This has been an on going problem with both of these thing for the last several months. I've also noticed that this is a common problem with Jettas my year. It's extremely dangerous. I can be in the city on a highway, anywheres and it'll randomly not want to go anywheres, the rpms will go completely up and still not move. I know from other, that there is an update for the ecu computer on the car, for the map sensor and to I guess he'll with the limp mode issue. I also know that when I hard brake, it'll go into limp mode. It's extremely scary.

42g8 recall 2015 also in Feb 2018 total loss of power when vehicle is a a complete stop as well as slowed to no acceleration once vehicle is slowed or stopped.

The contact owns a 2012 Volkswagen Jetta. While driving approximately 65 mph, the electronic power control warning indicator illuminated and the vehicle lost acceleration. The contact merged the vehicle to the road shoulder to a complete stop. The engine was turned off and then restarted. The contact stated that the vehicle had been experiencing the failure for approximately six months. The vehicle was taken to an independent mechanic (wallen auto ii in michigan city, indiana) for diagnostic testing and the accelerator pedal was replaced twice, but the vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 97,000.

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 wern'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 damn 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 shit, 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.

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.
