2019 Volkswagen Tiguan fuel system problems

Filed Sep 1, 2025 · Electrical, Engine · CA

My car has delayed acceleration issues of between 3 - 6 seconds. The last one that was 6 seconds ore more was on June 29. In addition it's happened several times. I took the vehicle in for its last service and was told the issue was my battery. Battery was replaced and issue not resolved. The service before that I was told it was a carbon build up. Continues to happen sporadically.

Was driving on the freeway in my 2019 VW Tiguan when I experienced a sudden unexpected loss of power. Warning lights came on and the car went into a "limp mode" not allowing the engine to rev past a certain RPM. I took the car to be serviced at a local dealership where it was determined that the Fuel Injector Harness was faulty and needed to be replaced. When I informed the dealer that there was an extended warranty on the harness (2018-2019 model years within 10 years/120 miles) and the part should be covered, the dealer and later VW of America said that my vehicle was not part of the warranty. VW of America could not explain to my as why my car was not part of this warranty, but it is obviously a known problem on their end and they should honor what they advertised with their warranty extension with the federal safety agency. [XXX] I find VW of America's response to this problem completely unacceptable and quite dangerous. Their unwillingness to take care of this critical component with a known failure rate unnecessarily costs consumers for repairs that VW should be honoring according to their own posted Warranty Extensions and could potentially cost bodily damage and lives.

Me and my family were driving to Los Angeles on a freeway. All of a sudden the car showed a warning saying something like "Limited to 4,000 RPM", and we felt strong vibration under the hood. We decided to pull over at a first available gas station. While turning into the gas station, the car refused to go and refused to start, making a loud clicking sounds. We had to tow the car to the nearest VW dealership (Galpin VW). Later they informed us that they have to replace fuel injectors and harness and it will cost us approximately $2,600. After paying the amount, I found that VW issued a recall/bulletin for this very problem - VWP-23-03 for my model year (VW Tiguan 2019). I contacted VW but they refused to honor the warranty claiming that the warranty does not apply to my VIN. It seem obvious to me that this is the same exact problem as described in the bulletin VWP-23-03. I feel like VW has made a mistake by not applying this bulletin to my VIN number (and probably others) and is endangering motorists that would otherwise get this serious issue fixed during regular maintenance.

Gear shift from gears 1 to 2 or 2 to 1, the gears often “slip” resulting in a slight delay or jolt upon acceleration. This is an ongoing issue that occurs frequently, for years.

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.

New car, 2 months old, 3,000 miles. Issue has happened 4x. First istance, turning left onto a major 3 lane road, car suddenly loses power and then chugs to catch speed leaving you powerless with the foot peddle to the floor. Second instance, exiting a shopping center, light turned green, stepped on gas peddle and car bogged and sputtered as if out of gas and stalled in middle of intersection. Once I got it started again it moved forward. At next traffic light it sputtered again and would not go even after pumping gas peddle. Creeps to a rolling run and then goes. Third instance was entering an on-ramp from a stop light, car sputtered as if out of fuel again and barely made it out of intersection where I had to pull off the road to get the car going. 4x same as above. I'm now at dealer for second time- no repair and they say vw is aware of some customers experiencing this issue no fix at this time. Very dangerous to drive on atlanta city streets. I'm nervous to put my family back in the car.

I bought the tiguan brand new from the dealership with high hopes for our family SUV. Almost immediately I noticed that the vehicle hesitated to accelerate from a stopped position a few times, but couldn't believe I was having a problem so soon after buying the car. When I realized that this was a recurring car issue and not user error, we had only owned the car for 3 weeks and the car had roughly 1200 miles. It was absolutely terrifying when I was turning left during rush hour traffic with my 12 month old son in the back seat and my car would not accelerate beyond about 5 miles per hour. Luckily the driver coming towards me on the main road slowed down with enough time for me to make my left turn and coast right into a nearby subdivision. I pressed my foot onto the accelerator to the floor and it took about 20 seconds for it to kick into speed. I took the car to the dealership where I assumed it would be fixed. After 9 days in the shop, they claim they drove the vehicle 80 miles and couldn't duplicate the issue. Therefore, they want me to put my family back into the car that is completely unsafe to drive. They tried to tell me that it was the "turbo lag" that I am experiencing which, in the long run, a manager admitted to my fiance and I is untrue isn't even what we are expressing as the problem. After talking to 3 managers, we finally found someone who is head of the service department at the dealership who sympathized with our issue and is letting us use a loaner until volkswagen calls us back, but this is only after I showed them all of the other reviews on this website that state our exact issue. Now we wait to see if volkswagen will do the right thing or if their customer service is as terrible as the dealership where we bought it when we went in with a real and terrifying issue. This is the beginning of what will be a recall. Unsafe and scary.
