Recently reported ENGINE problems on 2012 Volkswagen Jetta

The car has under 70,000 miles. the car needs a need vacuum pump and abs module!!!!!!! abs module is $2,200 dollars at the dealership. how does that brake so soon on a car?

Tl* the contact owns a 2012 volkswagen jetta. the contact stated that the vehicle stalled several times. the contact took the vehicle to first team volkswagen (6900 peters creek rd, roanoke, va 24019) at least twelve times to have the fuel system repaired in order to comply with the emissions test. the manufacturer was notified of the failures. the vehicle was not diagnosed or repaired. the approximate failure mileage was 161,316.

Out of nowhere the epc light and mil lights came on the car lost power and the engine was rumbling. very scary while driving on the highway. took it to the dealer. ignition coil and spark plug wires has to be replaced. cost me over $900. a day later, i see that this same problem was a recall on jettas in the past. i am out of pocket $900 and was nearly rear-ended on the highway because of this. why hasn't vw corrected this problem? i want to be reimbursed since this is a problem that has existed in jettas for year!

Jetta wouldn't start, called dealership and they said get it towed in, we have 12 other just like it, zero degree's outside, they told me about the inner cooler technical bulletin and they'd take of it, they said they would defrost it and look inside the turbo, they never did look inside the turbo they unhooked one tube and yeas moisture liquid came out they said not enough, that's not what they told me they were gonna do, its not a coincidence that 12 other cars are having the same problem, they didn't take care of it and made me pay for a new starter, totally unacceptable the 12+ other cars having the same problem. $84 towing and $480 for starter, they need to recall the turbo's causing the problems. unacceptable

Vehicle stalls randomly while idling and has happened twice will driving at low speeds, which causes loss of power steering. the car also drives rough before, and the stalling happens sometimes 3-4 times a day and other times not at all.

After stopping the car, the cooling fan remains on, and the engine seems inappropriately hot, yet i had not driven that far. ideas range from a blocked radiator, a poor thermostat? the coolant had been changed. has anyone else reported a similar problem? it was only 70 to75 degrees and often a bit humid, but usually at night since i seldom drove in the heat of the day. it was parked and the temp of the engine was never above 190 degrees, though the engine felt hot. this happened many times (10 plus) mostly during the winter in florida. i reported it once but the tech didn't see it as a problem.what do you think?

I bought the car in october 2017 and had to bring it back few days later because the water pump was leaking. they fixed it and couple weeks later i had to replace the heater core couplings because they were leaking. now in the beginning of december 2017 i was coming back from orlando fl from the dealership because i had to get my title from them, the car broke down completely on the highway. check engine light and a epc light came on as well. i had to get it towed back to my house and had multiple mechanics stop by and inspect the car but there was nothing they could do because of the tools they didn't have. i even called other mechanic shops that specialize in european cars. i finally had the car towed to the volkswagen dealership & they gave me a quote that was more than the value of the car. i also gave the dealership a call where i purchased the car from and they told me they would get back to me but never did until i called back with my mother and they said it has no warranty. then i called the westlake finance company for the car and they told me to go through the dmv. the car is not driveable.

2012 volkswagen jetta gli 2.0 turbo engine. the vehicle while in motion was misfiring causing speed reduction without notice, running rough while at an idle and would rattle under load ascending a hill. dealership service member said the tensioner chain was about to snap at only 80,000 miles on the car. continued to report if the tensioner chain snapped, the engine would die immediately. this could be a major issue with highway driving and the car unexpectedly stopped accelerating, these parts should last more than 120,000 miles, if not, the life of a vehicle. i consider myself lucky to notice the problem before it became a bigger and costlier issue.

Tl* the contact owns a 2012 volkswagen jetta. the contact stated that the engine seized frequently while driving and there were metal fragments stuck in the engine and transmission. in addition, the engine control module and battery indicators illuminated. the vehicle was taken to mckinney volkswagen (855-402-5098, 3600 s central expy, mckinney, tx 75070), but was not diagnosed or repaired. the manufacturer was not made aware of the failure. the failure mileage was 90,000.

My 2012 jetta gli timing chain tensioner failed, luckily mine failed at as i started up my car in morning, because it happened while i was on the road not only would it have caused more damage to my engine, but it would have caused some accidents. after having my vehicle diagnosed on what caused my engine to breakdown i learned that it was caused by a faulty timing chain tensioner, a known issue that vw has refused to aknolowedge but if yo9u speak to any mechanic that has delt with vw and audi they will tell you that is a well known issue.

The key will not come out of the ignition. we have tried everything possible and vw said this is a known issue but wont recall and have to pay 1000+ to fix. what if something happened with myself or kids in the car and needed to get the keys out!

The motor kicks(jerks) really bad. it has been happening for about two years. i have taken it to a couple shops and the volkswagen dealer once and no one has been able to detect the problem. i have changed many parts thinking it would fix it and still happens. at this point im frustrated and dont know what to do the car only has 84,146 miles. it does it when driving down a city street randomly and is very scary.

Tl* the contact owns a 2012 volkswagen jetta. while driving 15 mph, the vehicle stalled without warning. the contact was able to restart the vehicle, but the vehicle stalled again. the vehicle was towed to an independent mechanic to be diagnosed. the contact was informed that the failure was due to the timing chain slipping. the contact was given the option of replacing the engine or performing a timing chain service and valve replacement. the vehicle was not repaired. the manufacturer and the dealer were not notified of the failure. the failure mileage was 64,475.

Key gets stuck in ignition and i cannot turn off engine. this has been happening for weeks. when it first started it was only once and awhile but now every time i park my car it takes me twenty or more minutes to try and get my keys out and turn off engine.

Car would not start suddenly... vw dealership said engine needs to be replaced. there was no indication anything was wrong with the vehicle. it was driving normally, no abnormal noises, no check engine or other warning lights. luckily, we found out engine had failed when trying to start a parked vehicle. it may have been an unsafe situation had the engine failed while driving.

I am unable to turn off the engine when i stop. the keys are stuck in the enigen and the car not turn off. really heart breaking because i like volkswagen but i think this will be my last.

While driving at any unknown moment the car will start to misfire in 1 or more cylinders (seems like usually when there is moisture in the air) but you still never know when it will happen. this causes the vehicle to suddenly go into engine power control and will sometimes cut off the steering and brakes. i've gotten caught in the middle of an intersection with no brakes and no steering. i had to use my parking brake and shut the engine off. most of the time the steering goes out is when i'm trying to make a u turn. and most of the time the engine starts to misfire and/or shut off is when i'm trying accelerate either after being stopped at a red light or significant increase like merging on a freeway

Takata recall "water pump" i got many recalls on my jetta gli 2012 . the last recall i got on the mail was on november ,2016 for the airbag control . after i dropped my car for the recall i picked it up same day . i noticed that the airbag light is on for the first time i haven't had any issues like this before . i returned back to the dealer and informed them , they said you have to leave it and we're sorry we didn't take care of that . i didn't have time to leave it there for one more day . now they're asking me to pay for it around $992 ! i got all of the voicemail from the dealer they called me to apologize for the airbag light and asked me to come back to fix since it came up after i dropped it for the recall . also , i have showed the quote for the water leaking to many auto care centers in houston . they told me that this kind of car with 2.0 engine has a problem with the water pump and they will never get involved whit this car because to many people with the same engine and car model had the same problem several times . my car only got 60k mile on it and never been into and accident it's been less than 5 years now since i purchased the car . i paid 28k dollars cash from the first day just because i trusted in vw. i have contacted vw of america , but they didn't help me with my case and asked me to pay for it .

Coolant came then went off after shutting off car turning back then 3days later engine light came on while driving pulled over turnt car off turned on after 5 mins engine light cut off. 2 days later engine light came back on. *tr

The first thing i noticed after driving the car was the smell of burning oil occasionally, then upon opening the hood and removing the engine cover there was minor oil seepage from the valve cover. the car itself is 2012 jetta gli and only has about 27,500 miles as i type this message. but it gets worse, i notice the oil level dropping and having to put refill it about 2 or 3 times a month. at this point i know something isn't right and its not just a faulty valve cover gasket. did some reading online and i suspected it was a faulty oil separator/pcv system creating too much crank case pressure. i also checked the rear main seal recently and see oil leaking between the motor and transmission, suggesting the rms has began to fail. my question is if the car was "certified pre-owned" and pcv valve failure is some what common for both tsi and fsi engines, why wasn't the vehicles pcv inspected for failure or changed entirely with the new revision? there are many revisions on the oil separator/pcv valve from what i see. shouldn't the damage to the rms replacement be covered by the manufacturer since it was due to premature failure of the oil separator, that is known to be prone to failure or faulty from the factory? currently im not driving the car and waiting for the newest revision of the oil separator but since the rms has already began seeping oil its only a matter of time before it fails completely. being a trade school student who is lost his job right before christmas last year this unexpected failure of the rear main seal at only 27,500 miles, regardless of vehicle age is unexpected and at a severe inconvenience. if volkswagen cannot provide at least the labor cost for the rms replacement i cant say ill ever buy another vw from a dealership again. *tr

Tl* the contact owns a 2012 volkswagen jetta. while driving at an unknown speed, the vehicle stalled without warning. jim ellis volkswagen (5901 peachtree blvd, atlanta, ga 30341) diagnosed that the fuel sensor failed and needed to be replaced. the vehicle was repaired, but the failure recurred. the vehicle was taken to an independent mechanic and the fuel sensor was replaced again; however, the failure recurred. the vehicle was taken back to the same dealer for hard and soft diagnostic tests; however, the failure could not be replicated. the manufacturer was contacted and did not assist. the failure mileage was 45,000.

Key stuck on the on position and not able to turn key, to turn car off.

Had car in for new tires and after i left the mileage went from mid 40s to mid 30s, no engine service light, no partical filter light, returned to dealer and didn't offer to check it. 24,000 miles. is this something to do with dieselgate?

The vehicles engine would rev by its self with the pedal stuck to the floor and the clutch would not disengage during this leaving the vehicle accelerating on its own.

I had two no start conditions due to a frozen inter cooler. this happened in january a week apart. this happened while the car was in the garage.

Received verbal quotes to fix the issue with the key getting stock in the ignition with car running and was told it was not covered by vw and that it would cost close to 500.00 to fix and i chose to live with the issue...now i received a letter to get reimbursed for the cost when i did not have it fixed. called to set up an appointment and the dealer told me the car is over 100,000 miles and i would have to pay for it. this to me is not correct. i brought this issue up many times before the car went over the 100,000 and they claimed it was because the car was old...i would like someone to look into this and get back to me so i can have this issue fixed.

Tl* the contact owns a 2012 volkswagen jetta. while starting the vehicle, the contact noticed a burning odor emitting from inside the vehicle. the engine compartment caught fire. the fire department was able to extinguish the fire. a police report was not filed. the vehicle was towed to an auto body repair center, but was not diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was 55,000.

Tl* the contact owns a 2012 volkswagen jetta. while driving 20 mph, the vehicle accelerated forward in a jerking motion without warning. the vehicle was taken to the dealer to be serviced per a recall related to the failure; however, the failure recurred. also, a howling sound emitted from the engine and the oil and check engine warning indicators illuminated. the vehicle was taken back to the dealer, but the failure was not diagnosed. in addition, the contact stated that the headlights became inoperable intermittently without warning. the contact also mentioned that the front driver seat independently readjusted and the steering wheel shook violently when the vehicle was driven. the vehicle was taken to the dealer and an independent mechanic where it was diagnosed that the purge valve and the steering rack failed and needed to be replaced. the vehicle had not been repaired. the failure mileage was 66,000.

Engine runs rough, sputters and stalls randomly. when stalls, some lights flash and states service needed. dealership didn't find any faults. if stalls on highway this can be life threatening. steering wheel pulls hard to the left even with car properly aligned and tires air pressure reading accurately full. just had car serviced again no faults found. ignition issue with car not shutting off. 20 minutes after parking and trying to turn car off with no prevail. had car serviced and was gifted a free repair since my 2012 jetta has only 22,000 miles on it. ignition replaced but other issues still exist. paid out of pocket for servicing this vehicle multiple times since all these issues came about conviently after the warranty period ended.

I have a 2012 jetta tdi that is now just out of bumper to bumper warranty, except the 10yr/120k coverage extended on the known poorly designed hpfp (investigated in nhtsa action pe10034). i do a fuel filter change early 15k from the last dealer change at 44500 miles... and i find metal particles in the fuel filter. this is not normal, and indication of wear, and source is almost certainly the hpfp cam and roller/piston which is lubricated and cooled by diesel fuel recirculated to the filter via bypass, and some of this ends up in the fuel tank, and worse can end up in the injectors causing injector failure, even possible burned piston heads and catastrophic engine damage. i assume the path forward is document my findings, i did this with high resolution digital pictures, printed for the dealer, and a pristine white rag turned grey with metal filings, along with the old filter delivered for their inspection (i even provided the vcds diagnostic print out for the vehicles self-diagnosis). since i did the filter change, and about 100 miles and one day later, there is no more evidence of these metal particles in the system.. the dealer service department tried, vw would not authorize a pump replacement.. so i called and vw explained the situation to them, they did not bother to record name or vin, clearly not interested in customer care. official vw policy seems to be to ignore the metal filings and the customer, they offer a bogus explanation that metal filings could come from fill nozzles, or some other source (unlikely, i also own a diesel truck, and with longer service time, with more fuel used, there were no metal particles at nearly 30k miles. i now have a car i cant trust, knowing the hpfp can suddenly fail without warning and leave my family stranded, even cause an accident if it happens in a busy interstate, or when pulling into traffic.

Car lost all power and would not restart.i was driving about 55mph on a rural road, thankfully there was not a lot of traffic at the time the car failed. the glow plug light started flashing as the engine was losing power. there was no warning that the car would fail like this. i was able to pull off the the road in neutral. i suspected a high pressure fuel pump failure since vw had just sent out a letter notifying me that the warranty on that part had been extended to 120k miles. after it was towed to the dealership, they confirmed it was a hpfp failure and i am waiting to find out if vw will cover the repair. was told that this failure caused damage to the entire fuel system ($8,800.00usd). i do not see how vw can put a car on the road with a part that could potentially fail and cause this much damage.

Tried to start vehicle started once then stalled immediately. tried a second and third time vehicle would just click. let car sit 14 hours vehicle clicked once then started and ran rough with white smoke coming out of exhaust. read up on hard starts and found out about intercooler freezing. pulled tubing off and found approx. 2-3 oz of clear water and 4-5 oz of green sludge in the intercooler piping. numerous instances of this have occurred even on the highway some of these have resulted in a condition called hydrolock resulting in bent connecting rods. this has also occurred in vehicles being driven at highway speeds. at highway speeds this will cause a rapid loss of engine power possibly causing a vehicle accident. there are numerous forums noting this in 2009-2012 models and possibly 13-14 models. *tr

Engine would not start after standing in cold weather x 10 days. moisture from the intake air condensed & collected in the charge air cooler. this moisture then froze, and caused blockage of the intake air system. tsb issued in june 2011, amended september 2011, re: this issue. vw revised the charge air cooler design to avoid the formation of moisture and freezing in the boost system. purportedly, 50,000 jettas already affected; local dealer reports a car/day entering shop for same issue, and requires same repair @ $1300. vw will repair tdi's under warranty @ vw expense; those vehicles no longer under warranty are responsibility of owner. however, because vw knows of the problem, is aware of the tsb and issued the revised charge air cooler kit, vw will negotiate with owners whose vehicle is no longer under warranty. given the magnitude of this issue with jetta tdi's, why has there not been a recall? why is vw not assuming the liability for all these repairs, regardless of warranty status? would ask nhtsa to 1) recall these vehicles for repair, and 2) ask vw to assume liability for all repairs associated with this known design defect, & 3) ask vw to assume all costs, including parts, labor, towing, and car rental for us. *tr

Upon returning home on sunday 12/21 at 3 pm, smoke was coming from our garage. we opened the garage door to discovery my car on fire and a garage full of smoke. we called 911 and requested fire assistance. we then proceeded to extinguish the fire using 5 commercial size fire extinguishers. the fire department arrived and extinguished the flames and dragged the car from the garage. the car had not been driven for approximately 18 hours. *tr

This problem is diesel engine specific: -engine starts, then when pulling away, stalls immediately. -towed after multiple restart attempts failed dealer found water and sludge in intercooler, aka, intercooler icing. car spent overnight in warm service bay while it thawed out. vw has tsb for issue but i was told by the dealer that it doesn't fix it. wow. *tr

While traveling at a constant speed between 10 and 15 mph the vehicle began to jerk harshly, and after about 2-3 seconds of jerking the engine shut off. the jerking has happened many times, and has been getting worse over the past 10,000 miles. the vehicle has stalled twice now, once at about 68,900 miles, and again at approximately 71,500 miles. the second incident happened more quickly and in a parking garage and nearly resulted in a collision. the jerking happens at all speeds, including on the highway. *tr

With no prior indication, the engine glow plug light began flashing while driving on the highway. within few minutes, the engine light came on and car started to loose power. engine noise pitch changed, and was able to pull the car of the main freeway and barely made it to the dealership. as soon as we made it to the dealer parking lot, the engine cut off. diagnostic of the car showed that the car suffered a catastrophic hpfp failure which caused debris contamination throughout the entire fuel system. 4 days later, the engine had its hpfp, fuel lines, injectors, and auxiliary pump replaced. fuel tank was flushed and cleaned out from debris. cost under warranty was $5500. the dealer said that they've had 50 cars exhibiting similar conditions. cause of the failure is under investigation by vw. as owners, we have no clues what to do or when this will re-occur again which does not give me ant sense of confidence. i always fill at the same chevron station so it is not the quality of the diesel. *tr

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. *tr

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). *tr

On the afternoon of april 30th, 2014 while the vehicle was ideal at a stop light the vehicles power steering and a/c gave out. after inspecting the engine, it was determined the belt tensoner broke due to a faulty bolt that should've secured this part. this incident happen 6 days after taking it to a local authorized volkswagen service dealership . as a consumer and driver i feel a formal safety investigation must take place because a part such as this snapping off endangers my life and the life of the general public. this should become a major concern because volkswagen negligence to detail puts all drivers at risk of major injury and or death. *tr

I went on a road trip prior to this visit, and had a scary issue with my car where it hesitated several times while driving, it was hesitating like it was out of gas but i just filled it up with of course the recommended gas which is diesel. after a couple of minutes it stopped, which i found to be unusual cause its to new to be doing this. then i started to hear and notice that unusual noise coming from the front driver side of my car again but a little louder than before, it was annoying me so bad. i was hearing a constant rumbling, grinding noise while driving, the rougher the road the louder the noise, when i hit a bump the noise went with the bump, the smoother the road it was less loud but still there. i took it to vw and they had told me they scanned it and found no faults with the hesitation issue, than i took a ride with a technician who did hear the noise i was hearing, the technician even noted it on my papers. we then took out a similar vehicle but i could not hear the same noise, so the technician advised me to take it back again if it gets worse. i had told the technician it is not normal, no new car should be making these noises. not to mention the person who had sold the car to me never thanked me for the purchase as well as told me to never talk to him again, when all i was trying to do was to get some help from him, but he had treated me like garbage and made me fend for my own. on this visit they had supposedly done a multipoint inspection on my vehicle, and once again stated everything to be normal, nothing stating about my tires. *tr

When starting from a full stop in drive mode "d" i pressed the accelerator and the car responded with almost zero power to accelerate. it just rolled forward as though i wasn't pressing the accelerator at all moving 1 to 2 mph. after 5 seconds of pressing the accelerator and the rpm climbing slowly, it would achieve normal driving power. even at speeds of 20-30mph the initial response upon hitting the accelerator was the same lagging response. applying the gas pedal felt like starting from a stop with a manual transmission in 5th gear. i stopped the vehicle several times, even shutting off the car, without any change in the behavior during my 10 minute drive. after leaving the car off for half hour the problem didn't yet return. *tr

The vehicle tends to stutter, lurch, or hesitate at low speeds. this has caused several dangerous situations when attempting to accelerate into another lane or onto the road from a driveway. the dealer has informed me that this is normal behavior for thedsg transmission and there is no fix. an internet search shows that many other drivers have experienced this problem. i cannot believe that this is "normal" performance, and i am concerned about it. *tr

My jetta diesel engine was hydro-locked due to water being pulled into the engine from the intercooler. volkswagen has a tsb (technical service bulletin) published for this exact problem (frozen intercooler) - yet is only implementing or offering this tsb to customers on an as needed basis. in many cases - this is way too late. this is a known problem at volkswagen -- and by not offering this tsb to all vw customers -- catastrophic engine damage can occur - if the right weather conditions are met. for my vehicle, when starting up my car - at the end of the day, to leave and return home --> when starting the car - it acted as if the battery was dead. at this point, water was ingested into the 3rd cylinder, the piston rod of the 3rd cylinder was bent, and engine damage was done. vw should not be offering this tsb to all tdi (turbo diesel engine) owners who could be affected by the tsb. catastrophic engine damage by neglecting to perform a known tsb is creating a very dangerous situation on the roads. *tr

Tl* the contact owns a 2012 volkswagen jetta. while driving 70 mph, the vehicle stalled without warning. the contact was able to successfully move the vehicle off the highway by shifting into neutral. the dealer was unable to duplicate or diagnose the failure. the manufacturer was notified. the vehicle was not repaired. the failure mileage was 10,000.
