The vehicle experienced repeated catastrophic engine failures, including failure of a replacement engine. Approximately six months after purchase and at around 80,000 miles, the engine failed and required a complete engine replacement through Volkswagen and the MaxCare service contract. Approximately one to one and a half years later, at around 120,000 miles, the replacement engine also failed. The vehicle developed rough idle conditions, check engine light warnings, timing chain and camshaft-related issues, lubrication-related concerns, and severe engine performance problems. Volkswagen later recommended another complete engine rebuild or replacement along with additional engine-related repairs. The vehicle became non-operable and could no longer be safely or reliably driven. The repeated failure of both the original engine and replacement engine suggests an ongoing defect-related condition rather than normal wear or an isolated mechanical failure. The problems were confirmed and documented by Volkswagen service personnel. Similar engine-related concerns involving oil consumption, lubrication issues, timing system concerns, and engine performance problems are also reflected in Volkswagen Technical Service Bulletins involving this type of engine.

I had just had the engine replaced on my 2014 Volkswagen Passat TDI 13 miles previously and on my first drive upon getting my car back I had an error code “transmission overheated” and I lost power while driving and the check engine light also illuminated. The transmission cut out almost immediately when the overheating message illuminated on the dashboard. It then illuminated a wrench where the drive indication is not the dashboard and would not allow selection of any gears. I had the transmission inspected by the dealer and they aren’t sure what happened and that it does indeed need a new transmission. The fact that I lost the ability to drive the car immediately after the light came on while driving seems dangerous to me and a transmission with 63,000 miles and 64 degrees F shouldn’t overheat. It is a DSG transmission and I have read online of several other owners experiencing similar situations of the transmission having faulty parts and overheating. I also reached out to Volkswagen of America and they said there isn’t anything they can do as the car is out of warranty (I believe the warranty for the transmission was 60,000). I had pointed out to Volkswagen that the transmission is cooled by the engine so a brand new engine 13 miles ago and then the consequent overheating and terminal failure seems rather odd to me. Had I been driving on the freeway instead of 40 mph the situation could have ended significantly different then it did.

2014 VW Passat: EPC light and Engine light went on, 1/11/2022. Car stalled. Called AAA and waited awhile. Tried again and car started so I drove.... 0.4 miles and it happened again. AAA driver said it wasn't the battery (lights were still on). Towed to my mechanic. He changed the oil and gave me a new battery. I drove 600 miles roundtrip the next day. Then, on 1/22/2022 same thing happened. EPC light, Engine light went on and Car stalled. The fix: I needed a new Fuel Pump Control Module. Interestingly enough, my OTHER VW Passat (2006) had a recall on the Fuel Pump.

Vehicle engine light comes and goes way. The vehicle jerks/shakes when waiting the red signals and looses power and had to stop the vehicle and start the vehicle.I have done all the oil according to the recommended milage by the dealer. And also it looses power when taking turns, in that case need to turn off the vehicle and start again. This happens when vehicle waits the red signal and move/shakes heavily and had to put the vehicle in park and stop it. Though vehicle is 5 year and ran barely 55k and started showing symptoms as mentioned as above.I strongly believe this something to do with the manufacturing. Below is the report from the dealer. ------------------- cam faults, misfires. Scanned vehicle and found cam fault p034100, all cylinder misfires faults. Traced fault to timing chain tensioner failure. ------------------------ I have also attached the invoice and diagnoses results about the issue. And also found in internet related to the same issue that they have seen other vw vehicles. The issue seems to be similar, however vw/vw dealer seems not accepting and doing repair for free.

The heater core in my 2014 volkswagen passat tdi has failed and been replaced four times within the last 2 years. There is/was an extended warranty related to the heater core failure but there has not yet been a recall despite an obvious defect with the heater cores. Failure 1, 11/28/2016- reported as insufficient heat, primarily passenger side - warranty covered failure 2, 06/30/2017- identified by check engine light alert- warranty covered failure 3, 0/7/10/2017- identified by check engine light alert, warranty covered failure 4, 11/28/2017- reported as insufficient heat- primarily on passenger side- originally reported on 10/26/2018- vw declined to cover under warranty. Without a properly functioning heater core, the windshield defroster will not have heat. In this situation, the driver will have difficulty maintaining a clear windshield, which will create a hazardous situation. The lack of heat in the vehicle can also be unsafe in some climates.

We took the car in for maintenance to the dealership a month ago. It was a little loud which was evident. The dealers mechanic said the car was fine. A few weeks ago the check engine light came on (steady not blinking). We took it into the dealership and found out that the timing tensioner (apparently a known vehicle issue according to the mechanic), and that it had damaged the engine to the point it needed to be replaced. It has a 1.8t, and I am curious exactly how prevalent this problem is.
