Volkswagen Tiguan warning lights comes on

Filed Oct 16, 2026 · Electrical, Engine · CA

While driving a 2026 Volkswagen Tiguan in Los Angeles County, CA, the vehicle spontaneously and without driver input shifted itself into Neutral. The vehicle experienced a complete loss of motive power and stopped driving. I was travelling with my newborn infant in the back seat when the vehicle lost propulsion in active traffic, creating an extreme and immediate collision hazard. The vehicle had to be coasted to the shoulder under hazardous conditions. Car literally stopped in the middle of a busy intersection. Several dashboard lights came on during this incident. The next day the engine light turned on.

Suspected Electrical Defect and Potential Fire Hazard – 2018 Volkswagen Tiguan SEL I am reporting a suspected electrical safety defect involving the sunroof wiring harness in my 2018 Volkswagen Tiguan SEL. While my vehicle was parked, an attempt was made to replace a blown F23 fuse. Smoke began coming from the sunroof area and filled the cabin. Afterward, multiple warning lights illuminated, the vehicle displayed a “turn car off” warning, the door locks repeatedly cycled, the climate control stopped working, and the infotainment/navigation screen shut off and restarted. A mechanic subsequently determined that the sunroof wiring harness had melted and required replacement. I was informed that the wiring harness (part number 5NA971648C) is unavailable and has been placed under Volkswagen’s “quality inspection” process due to suspected fire-hazard concerns. Volkswagen reportedly no longer supplies this harness separately, requiring replacement of the entire sunroof assembly, including the glass, even though the glass is not the source of the problem. The repair is estimated at $3,900 and requires extensive labor, including dashboard removal and a VIN-specific part from Germany. My primary concern is safety, not cost. A wiring harness that melts and produces enough smoke to fill a vehicle’s cabin could potentially cause a fire, damage other electrical systems, or endanger occupants. I am concerned other owners may face the same hazard. I request that the federal safety agency investigate whether the sunroof wiring harness or associated electrical system in 2018 Volkswagen Tiguan vehicles presents a safety defect, review similar reports, and determine whether further investigation or corrective action is warranted.

Last night I was easing into braking to switch lanes when the car braked on its own. (Completely stopping) There was nobody in front of me, and the car isn’t dirty, so the sensors weren't blocked. We were almost rear ended as a result. All the dash lights randomly turn on. The sos always comes and also, the horn when I lock my vehicle it occasionally goes off. The usb connections occasionally work in it. The car pretty much has its days.

What component or system failed or malfunctioned, and is it available for inspection upon request? During a multipoint inspection that was earlier than advised due to multiple dashboard lights engaging, we were told that our car has an oil leak due from the timing covers and lower pan seal. They removed the oil separator and found value stem seals to be out towards the exhaust side creating an oil leak that stemmed from blown timing covers and the lower oil pan seal being the cause of the leak. The oil separator was noted as failed. This car has been brought in for every inspection and continued to have lights on post inspection that we were told regularly that they forgot just to turn off the lights but that the oil had been changed. In fact, our next oil change wasn't due until February 2027. How was your safety or the safety of others put at risk? Our safety has been put at risk driving a car with a substantial oil leak and faulty components that only seem found after we are 8,000 over the warranty. In searching the internet, this oil valve and leak situation is common in 2022 Tiguans enough so that there are multiple threads and articles about it. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer confirmed that this is an ongoing issue with these cars and that Volkwagen may be looking into doing a rebate for repairs. That doesn't fix the issue with the safety of the vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? We will be checking in with our insurance provider as well as an independent service center after dealing with Heritage Volkswagen Group due to our warranty. That warranty obviously provided us nothing for its cost or coverage. The lights were present and always brought in to be checked at the dealer we bought the car from. Again, we were always told that the lights didn't mean anything and they were left on after service accidentally

When driving, the vehicle self shifted into neutral and was unresponsive. All of the dash warning lights came on and I was not able to apply throttle or shift the car into drive. I had to coast in neutral to the side of the road. This is a safety issue and there was a high possibly of crashing if it wasn’t on a rural road. This is the second time this has happened. The first time VW service said nothing had occurred and gave me my vehicle back.

When I’m stopped, the car sometimes shuts off. The horn works intermittently. When I start the car, it feels like it’s going to stall. At times, all of the dashboard warning lights come on. Also, when I’m backing out of my driveway with nothing behind me, the car will sometimes automatically brake hard.

On March 12 warning message came on saying emergency drive system not available and then numerous warning lights came on and the car started to shake violently and went into limp mode. I pulled into a parking lot and called roadside assistance. It was towed to the dealership and has been there since. I was told it showed a misfire on cylinder 4 and has a faulty injector.

While driving the car looses all dashboard lights, brake lights, blinkers. The motor stays running and it has a check starter system message. Has done it several times in the 2 weeks we have owned it. Seems to only occur when it is hot outside. It is very unsafe to loose break lights, blinkers, and all info on dash while driving with no warning. It gives a pull over immediately message right after it does it. Taking it to auto repair shop this week to see what they say, but not very optimistic since I have been reading it happens a lot with this vehicle and rarely they figure out the problem.

Vehicle: 2025 Volkswagen Tiguan Incident Description: While driving at approximately 45 mph, about 5 minutes into the drive, my vehicle displayed a Lane Assist warning and a message to place my hands on the steering wheel. Immediately after, multiple warning lights and messages appeared across the dashboard. Followed my emergency warning message. The vehicle then suddenly applied the brakes on its own without any obstacle or hazard present. The brakes locked up, and the vehicle would not move. At the same time, the vehicle began honking and exhibited abnormal alarm/locking behavior. I had to restart the vehicle to regain normal operation. This sudden and unintended braking could have resulted in a rear-end collision, serious injury, or loss of control of the vehicle, especially at highway speeds or in traffic. The vehicle was taken to a Volkswagen dealership. The dealership documented that the brakes locked up and the vehicle would not move, but stated they could not replicate the issue and did not identify a cause or provide a repair. I do not feel safe operating the vehicle due to unintended braking and system malfunction. Date of Incident: 3/19 between 7:30 and 7:57 in the morning Approximate Speed: ~45 mph Location: Colleyville, tx No obstacle, hazard, or driver input caused the braking.
