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.

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

At a random time with nothing in the way the rear and front collision auto braking will engage. The last time this happen the vehicle was halfway into the street when it came to a sudden stop. Both forward and backward. I have a video of this happening. The local dealership says this a normal.

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while his wife was driving approximately 55 MPH, the vehicle lost motive power and stalled with several unknown warning lights illuminated. Since the initial failure, the failure occurred intermittently and the vehicle would restart soon after failure. The contact had taken the vehicle to a dealer however, the mechanic was unable to diagnose or duplicate the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 4,000.

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.

We bought a new 2019 tiguan for my 16 year old daughter. At just over 5 thousand miles, she was driving the car home from school when all the electric power was lost. The engine kept running, but she lost all the lights, headlights, break lights, radio, ac, speedometer, etc. Basically everything stopped working except the engine. Obviously this was a safety concern for me because she's 16 and didn't have headlight, or break lights, or a speedometer, just to name a few. Volkswagen dealership in mckinney, TX, began diagnosing the issue. They changed the battery and said the car was fixed. Unfortunately, as my now 17 year old daughter was driving, the car all the sudden lost all power again. The danger is that the car starts and performs perfectly at first, but will shutdown everything but the engine while she's driving! So this is the 2nd time this has happened. The car went back to the dealership and they a "software update", and claimed that corrected the problem eventhough I suspect they dint truly believe they fixed it. So my daughter starts her car and drives down the road with no problems, until, for the individual time, she loses power while driving over 50 mph. So the car is at the dealership for a 3rd time. The car has just over 5 thousand miles on it. Volkswagen keeps claiming they've corrected the problem, and keeps returning an unsafe vehicle to my daughter.

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while driving at various speeds, the vehicle would blow hot air. The contact had taken the vehicle to harper Volkswagen (9901 kingston pike, knoxville, tn 37922) where the technician inspected the A/C unit and found no fault with the system. As the failure continued, the contact took the vehicle back to the dealer where she was instructed to purchase a thermometer and keep track of the temperature readings inside the vehicle. The manufacturer was notified of the failure where she was informed that they stood behind the diagnostic of the mechanic and offered no further assistance. The contact also sent an email to the manufacturer documenting that the temperature reading inside the vehicle was above normal. The vehicle was not repaired. The failure mileage was 2,742. The consumer stated the vehicle was taken to a local fire department where it was determined the air from the vent reached 180 degrees.

Sunroof leaked while closed filling the car with gallons of water, creating water damage and risk of electrical failures. The vehicle was parked in a driveway. There is an existing class action lawsuit regarding this problem, however the owners were not made aware, and the soonest dealership appointment to remedy the issue was 1 week from the call, with no sense of urgency. This is unacceptable for a vehicle under mfg warranty, which is not safe to drive in the mean time.

Since my 2019 VW Tiguan was serviced in early July 2020 the horn has worked intermittently. It was first noticed when locking the car using the remote. The horn sounded only sometimes when locking the car by the remote. After recognizing this it was noticed that when driving or stationary time the horn worked about half the time it was pressed. The dealer claimed to have fixed it today (8/11/2020) and the horn worked when the car was locked by the remote on arriving home. On testing the locking again the horn did not work and we tested the horn by pressing it and there was also no sound again. I am returning to the dealer in stone mountain, ga again on 8/12/2020. This is a serious safety issue as one cannot warn pedestrians or other vehicles in an emergency situation.

I was beginning to merge South on I75 but pulled over on the shoulder before my speed reached approx 50 mph and I was less than.2 miles on the ramp. I immediately pulled over when I could smell and saw smoke coming out of the vents on the dash. Upon exiting the car I saw flames under the hood. While I was getting my children out of the car, a few men had stopped to help with fire extinguishers, but they were unsuccessful. The fire chief thought that the cause may have been an electrical short or some soft of manufacturing defect. I am not certain what caused the fire under the hood, but do know that I had not had any issues with the car until June 4th. It was a 2019 ;ease that I have been leasing less than a year. The car was brand new when I rolled it off the lot. It was in the dealership on 1/31 for scheduled maintenance.

Carnet in-car system doesn't work. Brought home the new 2019 Tiguan with only 5 miles on it and when I pushed the carnet buttons....nothing. Contacted the dealer and the service department took two days to try to fix it. I was told there was no fix. It's a software problem and VW must come up with a fix. Over 2 months later, still fix. This is a safety issue and very frustrated with VW.

Vehicle frequently shakes/shudders violently under light/normal acceleration in stop-and-go traffic, creating a safety hazard and extremely uncomfortable driving situation. I purchased it a few weeks ago and have approximately 1300 miles on it - this has been happening since I took delivery. Under load, shortly after the transmission shifts and as the vehicle reaches approximately 9-11 mph at 2000rpm, the entire vehicle shudders as if the engine is being lugged or is misfiring. This really only occurs after the vehicle has had sufficient time to warm up and has been driven for some time in rush-hour traffic. It is more pronounced with the adaptive cruise control turned on. The shaking/shuddering has made me extremely dizzy and nauseous to the point where I have already become physically sick to my stomach once. I had to cut off 3 lanes of traffic to reach the shoulder so I could avoid getting sick in the car - this was on 7/8/2019, a week ago today. Several passengers will no longer ride in the car with me. I have returned the vehicle to the selling dealer twice over this issue and although their efforts to diagnose it were made in good faith, they have been unable to reproduce it. I have several videos of this issue that I attempted to share with the dealership upon dropping it off the second time, which the service technician told me he did not view after I picked the car up. I also recently discovered that my emergency communication/airbag deployment notification system (car-net), is completely non-functional due to a software bug and will not work at all until Volkswagen comes up with an update for it (per the dealer). I am extremely uncomfortable continuing to drive the vehicle for these reasons and continue to feel sick to my stomach every time I use it to commute to or from my job, which is just over 30 miles from my home.

The automatic breaking sensors went off for no reason. Car started breaking on it's own. Luckily no car behind me. Car was in motion on a 35 mph part of route 30 in Indiana when it started to break suddenly. Took it to the dealership and they could not replicate it. I sent Volkswagen a message and they didn't reply.
