2019 Volkswagen Tiguan Electrical System

Volkswagen Recall: 28H7-Ignition Switch. In vehicles equipped with a conventional ignition switch, the polyfuse can fail, particularly when the vehicle is operated in high temperature environments. If the polyfuse fails, it can result in the engine stalling while driving and failure of the vehicle's electrical system, increasing the risk of a crash. When sitting in the sun, this has happened 5 or so times. Yesterday it was only 77 degrees outside and it happened. The electrical shuts off completely. No brake lights, no blinkers, no odometer reading, nothing. The windows worked once. And several times, the car will still drive; however it is terrifying driving in these conditions. After letting it sit in the shade overnight, the car wont start the first time and then usually starts the second attempt. I have had the car shut off one time after the electrical stopped working, my car shut off as well. This is the exact thing that is happening to my 2019 Volkswagen Tiguan; however, when I call the dealership, they say that this recall does not apply to my VIN #.

My 2019 Volkswagen Tiguan suddenly shut off on the highway with my children in the car. The vehicle lost all power, including steering, air conditioning, radio, navigation, and windows. I was barely able to coast to safety. The dealership diagnosed the issue as the ignition switch, part number 5Q1 905 865. This is the exact same part number included in Volkswagen’s current recall of nearly 50,000 Jettas for ignition switch failure. Despite this, VW has not expanded the recall to cover Tiguans. I paid over $700 for the repair, even though the part itself costs around $50. Worse, the dealership reinstalled the same recalled part number into my Tiguan, meaning the defect has not been corrected and could occur again at any time. This is a serious safety hazard. A sudden engine shutdown at highway speeds could easily result in injury or death. Volkswagen is fully aware of this defect but is refusing to extend the recall to affected Tiguan vehicles. I am requesting that NHTSA investigate this issue immediately and require Volkswagen to expand the ignition switch recall to include Tiguans equipped with part number 5Q1 905 865.

When it’s hot outside I get a warning about the starting system then all the electronics shut off including all dash, radio, and exterior lights

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while his daughter was driving in extremely hot weather, the fault code message stating that the ignition was switched off, check the starter system, and to please pull over to the side of the road was displayed, while emitting a beeping sound to alarm the driver. The electrical systems, excluding the engine, became disabled. The contact stated that the headlights, taillights, instrument panel, and several other electrical functions were inoperable. The driver coasted to the side of the road and waited until the engine had cooled off before continuing to drive. The failure occurred consistently, in approximately 2 to 3 minutes, causing the driver to repeat the actions for the vehicle to operate as needed. The vehicle was taken to the dealer who was unable to determine the cause of the failure. The code starter fault error message was displayed; however, the dealer did not believe the failure was related to NHTSA Campaign Number: 23V60400 (Electrical System); however, the VIN was not included in the recall. The contact stated that the Part Number: 521905865; for the ignition switch, was the same and believed that the failure was related to the recall. The dealer was unable to duplicate the failure because the temperature was not 90 degrees or higher. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 74,103.

VW has only issued an ignition failure recall for 2019 - 2021 Jetta's. I just purchased a 2019 VW Tiguan and because the recall does not extend to this model the repair to replace the ignition switch due to a failure that is identical to the Jetta is being refused. It is absolutely a safety risk and needs to be extended to include other car models of the same year. I was on my way to a mechanic when I lost all power to the car, the dash lights went out, and the check starter system error message popped up. It was 89 degrees here with overcast and was actually a lower temperature day when two days prior it was 100. CarMax specifically is only willing to replace the starter/alternator because there is no recall notice for the Tiguan. I am trying to get them to fully repair the car to a safer standard, but there is no guarantee without an actual recall for this model.

My car dash and all electrical components are shutting off WHILE I’m driving! All needles go to 0, radio shuts off, AC/HEATER, turn signals, brake lights, headlights, ect. The engine seems to run for a moment and then shuts off. Once the car is pulled over to the side of the road (if I make it!) and turn the car completely off and try to start it again, it won’t turn on immediately. I’ve had to sit for 5 -10 minutes on the side of the freeway multiple times on my way home from work as the car would continue to shut down on me. It’s absolutely terrifying. Luckily I wasn’t driving at night and was visible in the daylight and LUCKILY I didn’t have my children in the car with me when this has happened.

While driving the car a message appears " check starter system" and the car stops. This happened after about a quarter mile away of driving after starting the car. This has happened twice on really hot days. The first time it happened the car started back up normally, the second time (today) it did the same shut off three times before I had it towed. I am going to call the Volkswagen dealership tomorrow morning about this. I read online that the 2019 Jetta was recalled for what sounds like the same exact issue.

The system says ignition switched off. Please check the starter system. Then, all electrical system is turned off. It seems the same problem with 2019 VW jetta

The car automatically and inadvertently engages the parking brake while driving, as in approaching an intersection or in heavy traffic on highway. This obviously puts occupants and others at significant risk, as the driver cannot accelerate to avoid a potential collision, the car could be hit from behind, or the car could fishtail if the roads are snowy. It is wintertime and our roads are snowy, so we drive the car as little as possible. This first occurrence was more than one year ago. This initial warning in the car display is "Driver Door Contact Switch" error, particularly during cold weather, which precedes a cascade of other electronic alerts and activities described elsewhere, such as errors messages and sounds, and automatic engagement of the parking brake while driving. Some VW models have a recall for this exact problem, indicating that airbag deployment may also be affected: [XXX] This technical tip for many additional VW models indicates that the proper service procedure (error U019900) is to replace the door wiring harness: [XXX] The recall should be widened to include the models affected as indicated in this Technical Tip!! Our local VW dealer (which sold and services the car) claimed not to know anything about this common problem. At our first appt, they replaced the car battery. Prior to our second appointment (each requires ~4 weeks lead time), they said that they would not replace the wiring harness unless the error code occurred while the car was in their possession, despite multiple OBD error codes as cited in the technical tip above. The dealer ultimately agreed to replace the part only after (1) I sent a copy of the class action lawsuit; (2) I sent a copy of the relevant VW Technical Tip; AND (3) I said that I would pay for the repair (despite being covered under warranty).

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.

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.

Several times now, at outside temp above 90F, drive short distance and all electrical shuts.

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.

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.

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.

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.

FRONT COALITION SENSON AND WARNING LIGHT GOES ON FOR NO REASON WHILE DRIVING AT A LOW SPEED DISABLELING THE SENSON. 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!. DRIVER SIDE MIRROR LIGHT COALITION SENSON WAS ACTIVATING ALL THE TIME WHILE DRIVING ON THE HIGHWAY WITHOUT ANY CARS AROUND. NEVER NOTICED THIS HAPPENING BEFORE, BECAUSE I LIVE IN QUEENS NY AND I USUALLY DRIVE TO THE CITY AND I HAVE LOTS OF CARS ALL THE TIME SO IT'S CONSTANTLY TURNS ON AND OFF.
