2019 Volkswagen Tiguan: check engine light

Filed Aug 7, 2026 · Engine · NJ

The car, a 2019 VW Tiguan, had a “check engine” light come on, and the resulting diagnosis and repairs - using VW’s specific engine fault codes - led to the replacement of both water pumps at 72,000 miles. An investigation of the water pump problem on such cars revealed that Volkswagon previously settled a major nationwide class-action lawsuit (apparently kept secret) covering certain 2014–2021 models with 1.8L and 2.0L engines. This resulted in an extended warranty covering the repair or replacement of failed water pumps. For some reason our car was not covered by the extended warranty, even though the engines in the 2017 Tiguans are all the same. Why weren't we, as the owners of a 2019 Tiguan, notified of the results of the class-action lawsuit, and given the extended warranty? I want to know the difference between the water pumps in the affected vehicles, and the one in our car. The water pump # in her Tiguan is identified as O6L 121 111 M. What differentiates her water pump from those covered by the settlement? Why are we forced to pay a good deal of money to correct a pretty disturbing VW design flaw (a plastic water pump), when others aren’t?

The windshield fluid washer disappeared aka consumed mystery without the operator usage. I had to fill in a gallon of the windshield washer every2-3 months, and I did not do any washing or anything to use the fluid. Last week, the check engine came in and told me to fill the washer fluid and it could not pump the washer fluid onto the windshield while I was driving the vehicle during the snow storm that blind me visibility on the road that could cause a very serious accident if that happened. This is a very serious safety issue that could kill someone. as of today, 12/27/2024 I just filled the windshield washer fluid and it consumed 3 gallons of the washer fluid. The question is where all the fluid went even that I did not use it?

Road trip from VA to NJ approx 700 mi. Mid-trip, stopped for fuel and oil check. Thereafter, engine started to run rough. Check engine MIL on. Could not find any problem. Back on road. Received a low engine oil warning. Checked engine, oil all over back of engine compartment. Shut down engine and towed to nearest VW dealer. Found engine dipstick not completely seated. I checked and measured force needed to completely seat dipstick, at 30 lbs. Dipstick insert sleeve is plastic. Dipstick can be inserted to bottom w/o seating. Any leakage of vacuum from this engine causes extreme performance problems. Oil spewing in engine compartment is a significant fire hazard.

While driving an alert comes on that states check engine system. As soon as this happens all power in the car turns off. Engine is still running but you no longer have any turning signals, brake lights, headlights, air conditioning, etc. It happens randomly and has almost cause me to be rear ended due to car behind me not knowing I was slowing down or stopping. This happens when I am not close to a dealership so they have not been able to witness this.

When I turned the car on to leave work, the Check Engine and EPC lights came on, the car went into "Limp Home" mode and a warning came on the dash saying "Max Speed 4000 RPMs". Immediately, I could smell fuel, so I turned the vehicle off and exited. I noticed the ground under the car was wet. My husband came to check it out and the same thing happened. We saw that fuel was flooding out from underneath the engine. As he drove the vehicle to an adjacent lot to be able to be towed, fuel spewed out from underneath the engine. We had the vehicle towed to a VW Dealership in Grand Rapids who was able to diagnose a broken fuel rail bolt inside the intake manifold after they had the same experience with a massive fuel leak. Per the service advisor, this was not the first time they've seen something like this. Given the extreme flow of fuel from the engine, I'd say I'm very lucky that this didn't happen while driving through town or at speed on the highway where a vehicle fire would be possible with fuel pouring out of the manifold onto the hot engine.

Automatic start/stop feature malfunctioned while vehicle was at a complete stop in a left hand turn lane at the front of an intersection. Caused major traffic jam because vehicle would not restart. No warning signals were given prior to failure, car engine simply turned completely off and dashboard message then read to "manually restart engine". Attempted to do so but it did not work. After that, I randomly started turning the car off and on, switching from park to drive in whatever order to try to get the engine to restart since manually restarting the "normal" way did not seem to work. While the car was not restarting, the yellow engine light did appear, I am not sure exactly when. No one's safety was at risk in this particular instance, however it could have been depending on when this problem occurs. It has happened twice prior to this incident but both times occurred in a parking lot, not in open traffic. Eventually, after about 5 minutes the car did restart and I was able to resume driving. The vehicle has not yet been inspected by anyone for this particular issue and therefore not reproduced or confirmed by a dealer or independent service center.

I leased my 2019 tiguan in march 2019. Shortly after (~1,500 miles), I experience my 1st acceleration failure. While attempting to turn left with oncoming traffic (with my 4 year old in the back seat), my car would not accelerate although my foot was pressing the gas pedal to the floor. After multiple seconds and multiple attempts to accelerate forward, I put the vehicle in park, turned it off, turned it back on, put in drive, and was able to complete the turn. Thankfully the vehicles coming towards me were paying attention and halted, or it would've resulted in a collision. This failure happened 3 more times shortly after, 1 of the them occurring when my husband was driving. While getting my vehicle in for service, 1 of the vw employees mentioned they receive calls regarding this same failure every week, sometimes every day. A 2nd vw employee mentioned they have never received a call on this failure for my vehicle. ????. The dealership performed a 26m1 software upgrade that 'should fix the problem.' concerned for not only the safety of my family, but the safety of the drivers around me, I filed a claim with vw corporate and asked to be removed from my lease due to the failures almost resulting in multiple car accidents. They refused to allow me to get out of the lease as my experienced failures 'do not warrant the ability to be removed from the vehicle.' shortly after the software upgrade, my check engine light came on and I've experienced the same failure 3 more times (1 of them while attempting to reverse). Here we are again' I have a service appointment scheduled for 09/10 and opened my vw corporate claim back up.
