Engine, electrical system and powertrain issues among the top complaints received by the NHTSA from vehicle owners
When it comes to driving a compact SUV, there are some things that drivers demand. While style and space are right up at the top of the list, durability is also vital. VW claims that the 2019 Volkswagen Tiguan provides “bumper-to-bumper smiling” for owners. When we looked at what drivers have to say, smiling wasn’t one thing they expressed. Instead, they are quite disappointed at the faulty engine, electrical system and powertrain issues.

Problems with the electrical system
A high-quality electrical system is required to run the accessories in a VW SUV, but it also operates the essential parts as well. After all, the engine won’t start if there’s a problem with its electrical components.
In this first review from the NHTSA website, we see an electrical problem that can lead to a safety concern. “Front Collision Sensor and warning light goes on for no reason while driving at a low speed, disabling the sensor. This has happened about 5 to 6 times on various dates while driving in the city and I have to stop, turn the car off and on in order to reset the computer by itself. Sometimes it will turn off by itself too.”
What we see here is a significant amount of danger. It’s not much different from the threat posed by a recall labeled with NHTSA Campaign Number 18V824000. It appears that more than 70,000 vehicles don’t issue a warning when the key is left in the ignition. This leads to a heightened chance of having the car stolen. To fix the problem, technicians must reprogram the instrument cluster. With all the concerns caused by the SUV, some owners might wish it would get stolen.

Problems with the engine
While there have been a lot of reports about this engine being underpowered, there have been larger concerns posed.
One Edmunds review states, “Bought the first car and two days later the engine light came on. Took it in and I was able to get a new one. 4 days later engine light turned on again. Haven’t made my first payment and been to the dealership 3 times already. The first car had under 100 miles and the second car had 5 miles.”
The automaker seems to have a lot of complaints regarding the engine. They do address some specific incidents with Service Bulletin #TT 27 19 01 that talks about a malfunctioning start/stop system. In the bulletin, VW suggests that the problems are related to a poor battery charge. They tell technicians to modify the start/stop module to resolve the issue. In the meantime, drivers just have to make sure that the SUV doesn’t stop in the middle of an intersection.

Problems with the transmission
For a smooth driving experience, you want a quality powertrain. That’s not what the VW Tiguan seems to come with.
One NHTSA user wrote, “Upon driving my new 2019 Volkswagen Tiguan this past winter. It was a very cold winter day, when starting my car it wouldn’t go in reverse, then started to go in reverse. I put it into Drive. It would putt (go and stop) like it was running out of gas. There was plenty of gas in it. It continued to display the EPC yellow warning light. The light signal is engine control malfunction. I have notified my dealership I purchased it from. They state it will do that when it is very cold out. Now spring time, it has done it twice.”
The company has nothing to say about this or any other powertrain issues for that matter. It seems that they expect drivers to avoid reversing. Owners should only have to move forward when the weather is bad.
Problems with the brakes
Brakes are designed to stop a vehicle and help drivers avoid a collision. When something becomes defective with this system, everyone is at risk.
Just look at this review on NHTSA, “The vehicles brake line that went into the ABS system was not tight enough and brake fluid leaked out resulting in the failure of the braking system. The loss of the braking system could be felt while driving, and eventually resulted in the vehicle not stopping. Fortunately, no one was injured. The vehicle was new and had 185 miles on it when the brakes failed.”
Again, there is nothing from VW discussing brake repairs or fixes. Just like before, it’s likely that there are some owners that might wish the Tiguan would just keep driving away so they can get a new vehicle.
Problems with the vehicle speed control systems
One of the advanced features on the VW Tiguan is vehicle speed control. When this doesn’t function properly, it puts everyone at risk.
A review on the NHTSA website states, “I leased my 2019 Tiguan in March 2019. Shortly after (1,500 miles), I experienced 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 toward me were paying attention and halted, or it would’ve resulted in a collision.”
There is information provided for the techs in Service Bulletin #45-18-03TT on how to diagnose the trouble. They don’t issue a direct fix or cause for the unwarranted autonomous braking event that many people are experiencing. It’s clear to see that this SUV is a rolling disaster, when it actually moves. Otherwise, it’s just waiting to be stolen; although there can’t be that many thieves that want to drive this vehicle.
