2019 Volkswagen Tiguan

The read window defroster was not working well. A few days ago, when I turned on the defroster and drove for about 10 minutes, all of a sudden, the rear window made an explosion sound, and windows cracked like a spiderweb. I stopped the car and got out the car and shut the door, the cracked window shattered in pieces. It seems like the heating element overheated as the crack propagated from where the electicla wired were attached.

Started receiving error message “ 12v Battery Almost Drained, charge while driving” took it to a shop, they told me they battery was dead and replaced it with a new one. Checked the systems said everything else was working fine. Less than a year later the car is doing the same thing again. Car will not start and has to be jumped off.

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.

I put my groceries in the passenger side of my car and walked around to my driver's door. I touched the button on the door handle to unlock the door and it didn't work. I tried the key fob and it also did not work. I tried another key fob and it still did not work. I had to end up calling the dealership and they told me how to take off the door handle cover to use the manual key, which was difficult to pry off, and also scratched the car. This seems like it could be a safety issue. This could have easily been a mother putting her child in a car seat and walking around to get in the vehicle.

Error code: "Driver door contact switch". When this comes on randomly I can't unlock or lock my doors. I have had to climb out of my car through the passenger side door after parking because the driver's side won't unlock. Fault: "Auto parking break" When this comes on I can't turn on or off the parking brake. Sometimes when I'm driving and there is a bump or a change in surface level the parking break comes on. My car stops all of a sudden and cars behind me swerve not to hit me. I have noticed that the issues can go as fast as they come on. They only really happen in cold weather. Last year (2022) was the first year that things happened. I took my car in to see what Volkswagen could do. They said that because the error codes weren't running then they couldn't diagnose the issue. They also said that they have never heard of this before. However, when the error codes are on it's unsafe to drive the car. I have read that other Volkswagens have this issue. The link below is one example. https://knightlawgroup.com/volkswagen-tiguan-wiring-harness-automatic-braking-problems/

While driving at night the cars IP displayed a warning "ignition system shutdown please check your start system", the Instrument panel and information display then went dark with no symbiology speed, revs or turn signals. The head lights and tail lights shut off and cabin fan and side windows stopped working. The engine continued to run so I was able to safely exit the highway but was a stressful and dangerous moment. When the vehicle was taken for repair VW service says issue was caused by a malfunctioning battery which was replaced at my cost with an OEM part. this has not fixed the issue though and I am attempting to get a new appointment for service.

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The battery was jump started and the vehicle restarted. The vehicle was taken to the dealer where it was diagnosed that the battery needed to be replaced. The vehicle was then taken to two independent mechanics who tested the battery and determined that the battery did not need to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000.

From a stop at an intersection, the initial depressing of the accelerator produced no throttle response and then suddenly the car lurched forward. This resulted in rear ending the care in front at the intersection. The collision avoidance did not stop the car before contacting the car in front. Even after the accident the car continued to respond in the same way until it was placed on the two truck.

Blind spot indicator went out dealer replaced under warranty (passenger side) warranty expired a few thousand miles later and now the driver side is faulty. Vehicle has a rough idle and oil leaks. Dealer will not diagnose problem and now that car is out of warranty they wont do anything unless paid for. Car has rough idle and miscellaneous oil leaks occasionally almost stalling. Independent shop ran a diagnostic and shows one cylinder misfiring and want to inspect pcv as most the time these fail on VW
