Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2012 Volkswagen Tiguan owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2012 Volkswagen Tiguan. The contact stated that the vehicle was experiencing excessive oil consumption. Additionally, while driving at 65 MPH, the vehicle stalled. The contact was able to pull over to the side of the road. The vehicle was able to restart. The check engine, EPC, and TPMS warning lights were illuminated. The contact stated that the failure had been recurring while driving. The vehicle was taken to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 135,000.
The engine could not be started after 13 years and 103,000+ miles. I had to get the car towed to my garage at night, after several prior trips same day. There were no check engine lights or any other indicators. The engine had newer spark plugs, ignition coils and pcv valve installed as well as chain checked a year prior to this. Had a mobile mechanic come by and inspect the car. He determined that the engine has lost compression and that the oil was low. The spark plugs were soaked in gas because engine could not properly compress and ignite the fuel. After adding oil the problem did not go away. He performed the compression test and confirmed his suspicion about engine not being able to compress the fuel. The most likely cause was the timing chain issue but he could not inspect the chain to confirm due to difficulty of doing it. The engine valves were not moving as expected as well. …
At 77k miles the engine's timing chain jumped a tooth or two at startup. This seems to have destroyed the engine. Prior to that: no problems. My DTC scanner said the cam timing was off. VW wanted $25k to fix it after having it towed in. It sounded like rocks in a coffee can. It had just come from Chicago to visit and my son was stranded. I had to put him on a train home. I now am putting in a used engine for $9500 & it is going to take several weeks. When I looked on the internet I see this has been described as "a ticking time bomb". (REF Jalopnik.com). There was a class action law suit, but I guess --- since we had not had an issue--- redress was over. Still... 77k miles.
I was accelerating on the highway when my engine started making a rattling sound and the check engine light came on. I took my car into a specialty European auto shop and they determined my timing chain and tensioner needed replacing. The price is going to be over $5k and there are only 113,763 miles. I've always taken my car to a VW dealership for scheduled maintenance. As others have mentioned I never received a notice about this problem earlier from VW.
What component or system failed or malfunctioned, and is it available for inspection upon request? Defective Primary Engine Water Pump, yes. The original primary engine water pump system for a 2012 VW Tiguan 2.0 was replaced under the VW extended warranty in 2020 by an authorized dealer as a the result of the class action suit---please see Water Pump Class Action and Limited Warranty Extension bulletin issued by NHTSA. The replacement primary engine water pump system installed in 2020 has been found to be defective in March 2025 and the primary engine water pump requires replacement a second time -- without a warranty extension and less than five years from the date of service of the replacement under the Water Pump Class Action and Limited Warranty Extension issued by NHTSA. …
Gradual coolant leak with dealership knowledge upon sale of the car (44,000 miles). Refill overflow every 8 to 10 months. Leak unknown. Had to increase refilling gradually over time, thought it was due to use from work in 2016. Increased to once every few months 2017. Fill every week or two from 2018 to 2019....daily since late 2019 to now. Engine does not over heat. Refilling over flow coolant tank every time I need to drive the car. I have to turn on the car, pop the hood, and see how much it goes below the minimum line. Then fill to maximum. Daily refill started around October 2019. Received transmission flush and fuel induction service. Mechanic said I need a water pump and radiator. He thought the recall would cover my car but said my VIN wasn't showing a defect. I'm not sure why it's not. Dealership knew about the leak upon the sale of the car. Help!! …
My car had two recalls and I brought it in as vw of America recommended and I did have oil change at the same time on 2/19/2016. I went on vacation and when I came back I notice the vehicle drove rougher then before this service. On Wednesday 03/02/2016, I was on the freeway and notice my car lost brake function, I try using emergency brake and try down shift nothing work. I feel bless that I manage to avoid two car accident and it would of been my fault. I manage to hit the curb to stop the vehicle. I shift my car to park and shut the engine right away. Lots of icons indicator was on (airbag, ABS, engine...) and I took a video of the dash. I then call my insurance had it towed back to the dealer service. …
Check engine light came on and triggered code reflecting misfires. Dealership checked out and it is a carbon buildup on intake valves. I am told this is a widespread problem with direct injection sytems especially on volkswagens, bmws, audis. The suggested fix is to have a shop or dealer remove manifold and use a media blast of walnut shells to remove the carbon. This will only last until the buildup comes back. This SUV has approx 62,000 miles on it. The cost of getting the valves cleaned ranges anywhere from $400 to 1200. This problem is an inherent issue with design and there is nothing a consumeer can do to prevent it. As one repair shop said, it is inevitable and all direct injection engines will suffer this problem. I am appalled that there is no recall on this issue and when the dealer says it is a maintenance type item it really makes no sense to me. …
I have faithfully taken my volkswagon Tiguan 2012 to a vw dealership every 10,000 miles, as recommended, so I would save the life of my engine, it would be considered a certified preowned vehicle and last me 10-15 years. My car wouldn't start Saturday morning 12/16/18 in my garage, I had just driven it the night before and parked in it my garage about 8 pm. I had to have it towed to the vw dealership that has been servicing my vehicle.. They called me on 12/20/18 and told me my timing chain failed and that my engine had catastrophic damage and I needed a new engine which would be $9500. (?) really I then proceeded to call Volkswagen main headquarters. The gentleman took all of my information down, asked me what I think should happen and I told him I wanted help with repairing the engine. …
Timing chain tensioner failed (common issue with vw tsi engine) and caused an interference which resulted in a catastrophic failure of the engine during a regular engine start-up. This issue happened at about 115,000 miles and resulted in an engine replacement. The car was stationary and was working properly earlier in the day. The car was up to date with all recommended maintenance/ service tasks. Upon searching the web, it was noted this was a common issue to a point that there are several sites that offer "kits" to repair the engine (just search "timing chain tensioner issue + vw tsi" on google). …
