Electrical System owner reports: Volkswagen Tiguan years in the records

The records describe a possible fatal outcome.

“Engine keeps failing and dings while driving non-stop. Causes the vehicle to think there is another vehicle near me and activates the emergency braking in the middle of the highway almost causing me to crash. I have taken the vehicle to dealer and told it is fixed about 8 times now”

The records describe a possible fatal outcome.

“VEHICLE ENGAGES AUTOMATIC BRAKING SYSTEM WITHOUT ANY PROMPTING...NO OTHER VEHICLE ANYWHERE IN SIGHT. IT HAS HAPPENED ON A RURAL TWO LANE ROAD, WITH A FARM ON ONE SIDE AND WOODS ON THE OTHER AND HAS ALSO HAPPENED ON A 4 LANE ROAD WITHIN CITY LIMITS, BUT NO VEHICLE IN FRONT OF ME, BUT ONE TO THE REAR PASSENGER SIDE IN THE LANE HEADING IN THE SAME DIRECTION. EVERY TIME THIS HAPPENS IT BRINGS THE VEHICLE TO A COMPLETE STOP, REGARDLESS OF SPEED. I HAVE EXPERIENCED WHIPLASH ON SEVERAL OCCASIONS, AS WELL AS MY HUSBAND AND MY 7 YEAR OLD DAUGHTER. THE AMOUNT OF FORCE IS SO VIOLENT THAT I WOULD IMAGINE IT IS EQUIVALENT TO BEING HIT BY ANOTHER VEHICLE. I HAD JUST PICKED UP TAKE-OUT ONCE WHEN THIS HAD HAPPENED, AND THE SALSA IN THE TAKEOUT BAG FLEW OFF OF THE BACK SEAT AND THE FORCE CAUSED THE LID TO COME OFF AND SALSA WAS ALL OVER THE 2ND ROW, FRONT ROW, AS WELL AS MYSELF AND WINDSHIELD TO PUT INTO PERSPECTIVE HOW FORCEFUL THIS IS. I FEAR THE DAY THAT IT ENGAGES AND A CAR IS BEHIND ME, BECAUSE IT WILL KILL SOMEONE. WE ONLY DRIVE THIS CAR NOW ONLY IF IT IS ABSOLUTELY NECESSARY AND WE CAN'T MAKE OTHER ARRANGEMENTS.”

“2018 VW Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but VW is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.”

“The contact owns a 2018 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the parking brake independently activated, and the air bag warning light illuminated. In addition, while attempting to turn off the vehicle, the key failed to function as intended. The vehicle was driven to the shoulder of the road and turned off. The contact stated that while attempting to start the vehicle, several unknown warning lights were illuminated. The parking brake was not activated. Additionally, the front driver's side door latch failed to unlatch as needed. The contact stated that none of the electrical system features functioned as intended. The vehicle was taken to the dealer, where it was diagnosed with a failed wiring harness and a failed front driver's side door harness. The contact was informed that the wiring harness and front driver's side door harness needed to be replaced. The vehicle was not repaired. The dealer reset the codes. The contact was informed that until the repair was performed, the failure would recur. The contact referenced an unknown recall with a similar failure; however, the VIN was not associated. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

“My 2018 Volkswagen Tiguan experienced a failure of the airbag control module caused by water intrusion through the HVAC access area and failed seam seal tape at the cowl support. The dealership confirmed that water leaked through a factory seam, accumulated at the airbag module, and caused the module to fail. The airbag warning light is illuminated, and the system is inoperable. This failure matches the same defect pattern covered under Volkswagen’s recall campaigns for the Atlas and Atlas Cross Sport (water intrusion leading to airbag control module failure), but my VIN is not included. The root cause and safety implications are identical: water entering through a body seam/HVAC area and compromising the airbag system. This is a safety‑critical issue that disables the airbags and creates a risk of injury in a crash. I am requesting NHTSA review this defect for potential recall expansion. Dealership Findings: • Water present at airbag control module • Water leaking through HVAC access hole • Failed seam seal tape at cowl support • Water accumulation damaging the airbag module • Cowl trim cracked and repaired • Recommended replacement of airbag control module and seam sealing tape • Estimated repair cost: $1,377 + tax Safety Concern: Airbag system is disabled due to water intrusion from a factory seam. This creates a risk of injury or death in the event of a collision.”

“One time the car Just Lost power on the freeway and the e-card engine light came on and the cat Ran rugh and stalled and jerked hard almost causing me to cause a serious accident...I took it to vw and explained the severity and they bypassed that And installed a new water pump..2months later the same thing happened exactly to where I was very lucky and very upset...and took it to them once again and explained more issues where I'm urging . As to the front warning light and motion has came into play a few times witch was shocking...also the car would be on slow mo mode....and constant warning lights would come on the dashboard as well as the car would feel so unstable and Feel as if it were On gear 1/L while in the drive position...also the Eco turn of feature would playout ..and stall from time to time..then the car would get stuck on speed when foot would come off the accelerator to brake before a stop sign or red light intersection witch just started to concern me and I again took these concerns to Rick case vw and They thought I was inventing this story..then the car leaked coolant..and it rusted out the whole bottom of my car ..hoses...and they replaced the thermostat this time around and now the car has misfired..could not start ..idle was ver rough and just vibrated dramatically and damaged coils and spakplugs and blew out fuel inject #2 and can't hold pressure past 30 ..changed out the spak plugs and coils and the car is just crippled and its a safety hazard and in many occasions has almost caused me to cause a serious accident...”

“On September 19th 2025, while driving on the highway at normal speed, the instrument cluster fuel gauge misread the fuel level and indicated that the tank still had fuel. Without any warning light or low-fuel alert, the vehicle suddenly lost power because it was actually out of gas. I was traveling with my boyfriend and our three dogs. We became stranded on the shoulder of a busy highway as vehicles passed at 70–80 mph. The outside temperature was about 85-90 at the time. This created a serious safety hazard: The cluster’s inaccurate fuel reading prevented me from knowing we were nearly empty. The engine shut down unexpectedly, leaving limited steering and braking control as we coasted to the shoulder. We were exposed to high-speed traffic and extreme heat while waiting for assistance. Additional cluster/safety issues observed: No audible turn-signal “click” or indicator sound when using the blinker. No warning chime if the car is left running when the driver exits (for example, if the ignition is on but the door is opened or the key is removed). The vehicle is out of warranty, but the dealership diagnosed a failed instrument cluster and quoted about $2,500 for replacement. Why This Is a Safety Concern: The instrument cluster provides critical driver alerts. Inaccurate fuel readings, lack of turn-signal audio, and the absence of an engine-on warning chime all reduce driver awareness and can directly lead to dangerous situations on the road. Requested Action: I urge NHTSA to investigate whether the 2018 Volkswagen Tiguan’s instrument cluster/fuel-level system and related warning features contain a design or manufacturing defect and to consider a recall or other remedy to prevent accidents or injuries.”
