Car was taken into dealership in april 2015 for inspection. Needed new struts and driver door panel, door needed fixed due to no lights on locks and door itself would not lock. Paid $1400 for everything when picking up the car, got in car and radio did not work when picking up. Said it was a fuse, never fixed the problem. September 2015 windshield wipers quit working. $45 for that repair. 2-3 weeks later battery died. Replaced the battery for $111. 3-4 weeks later battery was dead again, had to tow it to shop. Replaced battery again $200+ parts and labor. 3-4 weeks later after replacing the battery twice, same thing happens again. Car is dead, towed to shop again. Can't figure out the problem, towed to dealership. Taken to a dealership for one problem of the car being dead now there is a shifter problem and the ABS unit needs replaced. The ABS lights were not on while the car was at the last shop before this dealership. The car hasn't been driven for approximately 5-6 months if not longer due to these issues. How does my ABS unit need replaced if it hasn't been driven?

Dead radio and battery has parasitic drain my radio died. The screen went black while driving and it has not recovered. Since then I have had battery drainage problems. One of the fuses, #42 I believe, has blown and I have tried to replace it, but it blows again as soon as the car is turned on. There are a number of online forums documenting this and similar radio problems with this vehicle. Here is one: http://www.cargurus.com/cars/discussion-t36009_ds552583 here is another: http://devforums2.tdiclub.com/showthread.php?t=389797&highlight=2010+jetta+dead+radio

Door locks failed and had to be replaced. Battery drain when not used for two weeks, requiring jump start (replaced battery one year ago). Car would not start (battery wouldn't even turn over, yes the same new battery) towed to dealer who said they replaced some fuses. Recently, radio will not power on. Dealer states the radio failed, fuses fine. I have seen 100s of reports of failed radios and door locks in the 2010 jetta. There must be a faulty electrical system in this vehicle. Cars that are 5 years old (I have seen reports of this happening when the car is only 3 years old) are not supposed to have these problems. All of these problems have occurred in the past year, mileage between 100-110k.

Built in bluetooth / radio is defective, leaving passengers unable to use hands free technology, and also eliminates the national alert system. The dead radio also leads to a parasitic battery drain, which will kill the battery of the car, leaving people stranded, potentially in extreme weather situations. This is a very well known issue with thousands of known cases online, yet nothing has been done.

Car radio suddenly shutoff while driving and would not turn back on.touch screen does not respond. Checked fuses on engine component and left side panel, and no fuses are blown. Now the passenger headlight and driver's side taillight are also out, but replaced with new ones they still do not come on. Very concerned that the electrical issues will drain the battery and that there is no apparent cause for this incident.I do not seeing a new radio as being the solution, I refer to this discussion http://www.cargurus.com/cars/discussion-t36009_ds552583 with very similar issues to mine.

Touch screen radio on my 2010 vw jetta tdi stopped working a few weeks ago. At the same time the A/C began to fail. This week after researching why the radio stopped working came across many threads discussing similar issue and the term "parasitic drain". This problem causes the battery to be drained. Woke up this morning and I got in the car and the battery is drained. Will try the dealership once it opens.

The radio unit stopped working after 4yrs of use, the safety concern is the lost of bluetooth and the ability to conduct hands free cellphone calls / operations the broken radio drains the battery causing family to be stranded at night until the tow truck to arrive.

After getting my 70k mile service and leaving the dealership my radio died. Went back to shop and the service department checked the fuses and verified that power was getting to the radio. Reported it had just "died". They did not acknowledge this as a trend, however, my service advisor admitted that another customer has replaced his radio 2x - also a 2010 jetta. This is not a luxury item, as I travel long distances for work and use the "hands-free" function of the radio system for making calls safely. I understand there are at least 65 other formal complaints regarding this issue, and several people have reported that this problem can and does drain the battery. This is about the third battery I've had in this car of 4 years - seems a little fishy. This is a safety issue, and more importantly, a defect which should be recalled!

Successfully starting and driving the car for 3 days of below freezing temps at 40mph average. Put car in 40deg garage overnight. Started car in the morning in garage, it ran for about 3-5 seconds then stopped. Restart acted like dead battery; half turn of crank, then nothing. Suspecting a dead battery, I put a charger on and tried again half an hour later; still no start, just half turn then nothing. Tried again about every half hour for 3 hours until it finally started, then it seemed to be running on 3 cyl for about 15-20 sec until it started to run smooth. Took to dealer where they tested battery and charging system; everything within specs and no codes. They kept car outside overnight at 20 degrees and it started right up the next morning. I investigated this issue on several tdi forums and it seems this is attributed to ice forming in the intercooler then thawing when warmed up. Engine will start normally until it ingests the water/vapor that shuts it down. Several owners are reporting half cup to two cups of water drained out of intercooler hoses. Several owners are reporting engine either shutting down or going into limp mode on highway after ice blocks intake sufficiently. Most are suspecting the lp egr circuit that is pumping moist air back into the intake/intercooler causing condensation to accumulate then freeze. I notified dealer when they had the car and they did not investigate water in intercooler as requested. I suspect this is hydrolocking the engine and that serious engine damage will occur if this continues during the cold months. Several forum members in canada are reporting that vw of USA knows about this and is working on a solution but nobody has seen anything yet. Several dealers are recommending the removal of the fresh air intake pipe to draw warm, underhood air into the intake; this does not seem to affect the icing as the moisture seems to be coming from the exhaust stream via the lp egr.
