Volkswagen Jetta owners have reported 12 problems related to timing tensioner (under the engine and engine cooling category).
First my car had trouble turning over after a misfire. Then while driving the car (in motion) as I was coming to a stop the engine began to sputter and feel as if it was lunging forward. I drove it straight to the vw service center which was nearby. Now they are telling me it is a timing issue which I suspect to be the timing chain tensioner.

A failed tensioner causing the timing chain to snap and bend the valves.

My timing chain tensioner failed and bent 14 valves. All 4 cylinders had zero compression. Volkswagen represents in the warranty and maintenance schedules that the tensioning system is expected to last for about 120,000 miles without the need for repairs. In fact, according to the plaintiff, owners are provided manuals that do not show any timing chain system inspection or maintenance schedules at all.
My wife¿s 2010 Jetta 2. 0t tsi experienced an engine stall and complete loss of power while driving at approximately 40 mph on a straight section of city street. This was a routine trip under clear weather conditions. With no traffic behind her, she safely coasted to the side of the road. After waiting 5-10 minutes she was able to restart the engine and, with no check engine lights appearing, drive approximately four miles home. The following morning, upon starting the engine, multiple cylinder misfires began occurring and the engine was immediately shutoff and the car was towed to the dealership for diagnosis. The dealership discovered that the stall was due to the timing chain tensioner failing, which allowed the timing chain to skip six teeth on the camshaft and the valves to contact the pistons resulting in the engine self-destructing. They recommended a nearly complete engine replacement at a cost of over $8,000. The car was purchased brand new in 2009 and has been maintained impeccably as specified by vw. Speaking with the dealership engine technician, we learned that the timing chain tensioner is a known defective part by vw and that in 2011-2012, was revised several times in an attempt to mitigate the failures. A technical service bulletin was issued by vw to dealerships and service departments explaining the issue but no notices or recalls were sent to customers informing them of this potentially deadly component failure. I have read, but not independently verified, that vw has issued a recall for this specific component in europe. Since the beginning of 2016, and owing to the significant safety hazard, as many as three class-action lawsuits have been filed against Volkswagen for this specific component failure. We are thankful no one was seriously injured or killed when the car stalled during operation, but now we are facing over $8,000 in repairs.

I am requesting that the dot NHTSA investigate the timing chain tensioner in this make and model of car. I started my car one morning and the engine made a metallic rattling sound as I proceeded to back out of the driveway. No check engine light came on until reaching the end of the driveway. Car was then driven to dealership immediately and diagnosed as having "jumped time" due to the failure of the timing chain tensioner. Upon picking up the car several days later after the repairs were complete, the service advisor informed us that that the metal ring holding the tensioner latch in place had fallen off; allowing the tiny adjustable latch to fall out, and that both pieces were lying, loose, in the compartment when the car was taken apart. This failure appears to be related to technical service bulletin 15-12-01. A web search reveals that this problem has become more and more common and affects multiple years and models of Volkswagen automobiles. The car had approximately 49,000 miles on it at the time of the failure and never missed a service. Vw was notified of the failure.
The contact owns a 2009 Volkswagen Jetta. While the vehicle was parked, it failed to start and the check engine warning light illuminated. The vehicle was towed to a dealer where it was diagnosed that the timing chain tensioner fractured. As a result, the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 88,020.
The timing chain tension broke causing the chain to break off and bend several values causing extension damage to the motor. Most cars are equipped with timing belts but vw went to the timing chain in return the tensioner which they later revised is faulty and breaks causing the chain to destroy several important parts. Vw is unwilling to help us with this issue that they know is an issue because they later corrected in the later models. I called customer care but because the power train warranty at 60,000 is expired they will do nothing. There is a huge forum started with several people that have had this use around 80-110,00 miles!! I am outraged and have to spend thousands of dollars to repair all the damage or basically get a new car. The car is worthless at this point.
The contact owns a 2010 Volkswagen Jetta. The contact stated that while driving at 50 mph, the vehicle stalled. The contact was able to restart the vehicle. The vehicle was taken to a dealer but the contact was unsure about what part needed to be replaced. The vehicle was repaired. However, the failure recurred and the check engine warning light illuminated. The vehicle was taken to a dealer who diagnosed that the gasket, sealant, the oil separator, the timing chain tensioner, the timing chain, the timing chain case cover, the timing rail tensioner and multiple other unknown parts needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 90,000. The VIN was available.
The contact owns a 2005 Volkswagen Jetta. While driving approximately 40 mph, an abnormal sound emitted from the engine compartment and the vehicle shut off as the check engine warning light illuminated. The vehicle failed to restart. The vehicle was towed to a dealer for diagnostic testing. The mechanic stated that the timing chain and timing chain tensioner needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 100,000. Ma 08/06/15 updated 8/14/15.

Timing chain tensioner failed resulting in engine failure.
Car has thrown a cel of p0016. Timing chain tensioner is shot and needs to be replaced along with chains, guides, and possible valves. This is a problem with 2005. 5 and 2006 Jetta 2. 5 engines.
