While driving on interstate, without warning or change of throttle, engine slowed noticeably. Unable to maintain highway speed without high fuel consumption and dangerously slow acceleration. Dashboard light indicated problem with glowplug (diesel engine) and check engine light stayed on. Took to local dealer next day; tech replaced "pressure pipe" (faulty charge pressure sensor on high pressure filter pump) and "flashed" ECM. Engine's acceleration still below what it was prior to event.

My vehicle is a 2010 Jetta tdi sedan, purchased in July, 2010 in frederick, md. There are now 10,000 miles on the car. Within weeks of purchase, I began noticing a hesitation in the engine after cresting a hill and proceeding down the other side of the hill with my foot releasing somewhat from the accelerator. The hesitation lasts for several seconds. Next, at approximately 1900 RPM the engine will occasionally hesitate and even buck. Most importantly, on three occasions the engine has continuously hesitated during my 35-mile commute. The feeling is akin to a gas engine running lean or out of tune. When I arrive home and turn off the key on these occasions, there is an astounding amount of heat surrounding the engine compartment, and the automatic cooling fan kicks on and runs for five minutes or more. The car is currently in the dealer repair shop, where I was told that the high pressure fuel pump contains metal shavings and is in the process of destroying itself. I am aware via the internet that others have had similar problems with the tdi engine and that VW has tended to blame the problem on customers adding gasoline to the fuel tank. I have most definitely not used gasoline at any time. I wanted to add my voice to others, so that VW can be encouraged to remedy the situation properly.

1. driving normally on highway when it came on and the car lost power suddenly and could not accelerate any further. Also car stalled several times on its own while idling at a traffic light (its an automatic transmission this should not be happening). 2. this is the second time this same problem has happened in first 20K miles of this vehicle its an 2010 VW tdi. First time it was at 9800 mile mark same light and problem came on they replaced a egr valve and now again at 19800miles. 3. they have replaced a part at 9800 miles and now replacing it again at 19800miles. It seems to be a repeat problem with this vehicle and very dangerous to have it slow down like that while driving and also stall out while in traffic.

I have a 2010 VW Jetta tdi diesel sportswagen that I purchased new. The car has 12,000 miles since new. The car has been maintained by an authorized dealer per the recommended maintenance schedule. While driving the car it suddenly lost power without warning, requiring immediate action on my part to avoid a major accident. The car's warning system displayed check engine and service required annunciation. After the power loss. The sudden complete loss of power concerns me regarding the safety of driving the car, I've since been online and read the accounts of dozens of owners that have had this same problem with the 2009-10 tdi VW Jetta. All seem to be related to fuel pump failures. The car will be towed to the dealership tomorrow for service. But looking at the other accounts of this problem, it would appear that the dealerships are not having complete success in resolving this problem.

- Evergreen, CO, USA

After crawling in traffic for about 30 minutes the car stalled. This is the only time this has occured but I do not drive the car often. Since this occured 1 week after the car's first service, I have not brought it into service yet.

- Wayne, NJ, USA

2010 VW tdi ----- check engine light at 9800 miles. VW says "contaminated diesel in filter area" and "not covered under warranty" they believe they can make our auto insurance pay...showing a little gunk or rusty sheen within filter canister area. Will keep calling VW warranty...trying to have the +$6,000 repair covered. I believe this car suffered fatal hpfs failure.. 20 full tanks of fuel since purchased new - all from race-way or murphys(walmart) ulsd no further evidence of contamination in tank.....yet. Car still at VW.

I have 2010 VW Jetta tdi, 6 speed manual transmission with 30K miles on it. As I was trying to merge into traffic, I tried to accelerate and the car would not go'it acted like it died. I had a car right behind me and another one merging from the right so I had no place to go but forward. I downshifted and still no power. Eventually, and thankfully without a crash, it gained momentum and it didn't kill. For the next 5 miles or so, it continued to spit and sputter and as I was coasting down a hill without the car being in gear, I revved up the car to listen to the engine and it would not go beyond 2100 RPM. I made it to work and had no more problems yesterday. I immediately called the dealer and will be dropping the car off today for diagnosis. This 'stalling' has happened in the past for me, maybe 6 times, but it was not abrupt or alarming so I thought it was just me trying to accelerate in a gear that was too high for the power I needed. I have used nothing but the recommended diesel fuel and have never put regular gasoline in it. I am the only driver of this car. Hopefully, I don't get the run around but am afraid of what is going to happen because I only have 6K miles on the bumper to bumper warranty. We will see what they say today.

2010 VW tdi Jetta sportswagen currently has 18675 miles, however, problem started at approximately 5000 miles. Engine feels like it loses power and starting to stall when in 3rd/4th gear and between 30 to 40 mph. At times it is like a small hiccup at other times it is quite severe and causes the car to lurch violently - has locked the seat belt up when this occurs as I am thrown forward hard. Occasionally same thing will happen in higher gear, but pretty much every day in 3rd or 4th gear. Have taken the car back to the dealer multiple times and complained about problem each time. Response has been they cannot duplicate and can find no problem. On last service they replaced the fuel filter said it "might" be clogged. No improvement - problem still happening. Buy my diesel fuel from the same stations all the time and the same stations I purchased diesel fuel for my 2004 golf tdi with 150,000 miles on it and never had any problem with that car.

2010 VW Jetta sportwagen tdi "glowplug" light begins blinking, loss of acceleration while driving at highway speed. I am from fl and was in the houston area at the time. Drove car to nearest VW dealer. Dealer found metal particles in the fuel filter and I had to rent a car to get back to fl. The repair took 2.5 weeks and the car was trucked to my local VW dealer. I was never told the cause of the issue and have seen in several forums that this problem can occur multiple times.high pressure fuel pump disintegration is suspected cause. Besides the safety issue of sudden loss of the ability to accelerate, I am concerned about future failure due to faulty fuel pumps (if that is the cause) and the $9,000 repair cost.

- Jacksonville, FL, USA

My 2010 Volkswagen Jetta sportwagen tdi with 18,000 miles was making a very rough sound shortly after a non-cold startup. A few minutes later, the engine ground to a halt with a loud crunch sound and shut down. Vehicle was towed to a local Volkswagen dealership. Dealership found problem to be a high-pressure fuel pump failure. Diesel fuel in tank was not contaminated. Volkswagen replaced the entire fuel system under warranty.

Brand new Volkswagen Jetta sportwagen tdi has stalled at speeds from 25-65 mph with absolutely no warning (no warning lights or messages and no change in driving performance). This has occurred 3 times at approximately 4K miles. The 3rd time the car had to be towed from a major expressway since the engine would not restart. The VW dealer found fault code P2146. They did not find anything wrong with the car during testing and simply cleared the codes with the assistance of a VW of America technician working remotely. The VW of America tech advised test driving 20 miles and returning the car to us. The car worked well for the next 5K miles but has now stalled randomly again twice while driving. I was nearly hit today as the car stalled in the middle of an intersection as I was turning left. Prior events have led to nearly being rearended on 4 lane highways with 2 adults and a 3 and 5 year old in the back seat. This is my first new car and I have never felt this unsafe in cars I have owned that are over 10 years old. VW seems to think it is ok to return this car to customers and will not provide me any information on the frequency of this occurrence in this make and model across the country. I am having it towed to the VW dealer (sutliff in harrisburg pa) where I bought the car. They indicated they will work on the car again. I'm afraid this will just mean clearing codes and test driving. The mechanics have all agreed that they would not feel safe driving their family in my car...my new car. Note: Rvutb 2414/yl 2.0L tdi ECM softward update was performed on this car as part of recall between incidents.

- Camp Hill , PA, USA

2010 VW Jetta sportwagen tdi fuel pump failure. I had to replace the entire fuel system at a personal cost of $9,980.52. I was told it was due to contaminated diesel fuel but I have an engineering report that proves the fuel was within guidelines and not considered contaminated by industry standards. It has not recurred but I can't be certain it won't since I have no idea what caused it. VW is denying warranty coverage. I have learned of a few dozen cases nationwide and in most cases VW did cover the others. One or two have reported a repeat problem. I had only owned the car for 7 months and had 8,076 miles on it at the time.

Hesitation after stopping and then accelerating. Auto feels like it is about to stall. Hard shifting from 1st to 2nd gear.

- Las Cruces, NM, USA

Yesterday (18/09/2010), my 2010 Jetta tdi stalled for 1-2 secs when we were crossing to another side of the street after picking my son from a birthday party. We were almost rammed by another car which was going at a high rate of speed. The engine stalls for 1-2 secs before going again even though I had stepped the gas pedal all the way down. It refired again and sped up again. I don't know what have caused this but my oldest son also noticed that during his everyday driving to university. Have reported to VW Canada website complaint today (19/09/2010). Especially occurred in first and second gear.

On Friday, Sept 10, 2010, while driving South on the I 605 freeway (los angeles county) at approximately 12 noon at speeds of 60 to 65 mph the engine, without warning, died, stopped. I managed to get onto the shoulder and eventually restart the engine. This failure happened two more times on the freeway. On the final stop, after calling VW, I was able to restart the car and complete my drive home (approx. 60 miles). That evening while driving to the local market the same thing happened with the engine two more times. I notified the drew VW dealership of the problem and arrangements were made to use their roadside service and have it towed to the carlsbad, ca dealership for diagnosis and repair. It has now been there three days. An additional frequent problem is the engine stalling when leaving a stop.

2010 Jetta tdi stalls when starting out. Mostly occurs in 1st gear and sometimes 2nd gear if slowing down (to take a turn for example). It seems as if it needs to be given an extra surge of fuel by depressing the gas pedal more than usual in order to get past this point. I have been driving a manual for 15 years - 4 of them Jettas - and have never encountered this kind of 'play' in the clutch. This makes for an incredibly dangerous situation when pulling out onto a highway with oncoming traffic. Even knowing the potential for stalling and compensating, I still stall at least once a week. I'm not sure if VW has acknowledged this as a serious problem yet, but I would hope it is investigated and that a fix is made known asap.

High pressure fuel pump failure caused car to stall at highway speed, ~68 mph. Pulling off freeway with dead car caused a minor fender bender.

2010 Jetta tdi manual transmission--clutch stalls dangerous due to new clutch response combined with diesel turbo lag. When I purchased my new car, the salesman at VW of langhorne, pa, was certain that I would "kill the clutch" on the first drive as had all other people who purchased a manual 2010 tdi. The clutch response is somehow different than any other car and after adding the "diesel turbo lag, " it makes for a dangerous first acceleration. To my salesman's surprise, I did not stall the car when I drove it off the lot. However, I have since stalled it several times in traffic. When the clutch stalls, driver must completely turn off ignition and turn it back on before attempting to clutch-drive again. This is a known issue among 2010 manual tdi owners and one frequently discussed because it is very dangerous. Some owners on "tdi club" list server are changing out their own clutches to stay alive. I am an excellent "stick" driver with 25 years experience in many vehicles. Something needs to be done about this clutch issue before people get killed. It's not my driving problem or my particular car's problem--it is a problem with all 2010 manual tdi clutch starts. I cannot let anyone else drive my car, even my own husband (who drives a 2003 manual tdi golf), because I am afraid he will get killed pulling out in traffic as clutch stalls are frequent with the 2010 manual tdi Jetta model--even after you get used to it. I previously owned a 2001 manual tdi Jetta and drove it for 10 years with no clutch complaints. I stall the 2010 clutch at least once per day. When my husband has attempted to drive it, he stalled it five times in a row the first drive, and in subsequent drives stalls it every other pull out. The problem is most dangerous when leaving a driveway, parking lot, or making a left turn with what would normally be enough space in the flow of traffic, but what is not enough when the clutch stalls the car.

- Clayton, NC, USA

2010 Jetta tdi (diesel) - at less than 3,000 miles, the car began stalling when accelerating from a complete stop. This has occurred at least six times. Have to release foot from accelerator and re-apply in order to get car to move ahead; sometimes it takes multiple attempts to get the car to move. Once power is established, the car lurches forward at full power. The car currently has less than 6,500 miles. The stalling has occurred with oncoming traffic heading toward us and creates a very dangerous situation. Car has been to dealership several times for other minor issues, and is currently at dealership undergoing more research and work related to this problem. Another problem which started at around 5,000 miles was when I put the car in gear to drive, I heard a ratcheting-type of sound. This has happened at least three times. Dealer checked this out and advised no problem found.
