Electrical System Problems of Volkswagen Tiguan - part 1

Vehicle threw sos emergency call feature error two years ago. I replaced the module at the dealership. Today, the same sos emergency call feature again showed up and I am unable to make an emergency call. This is a known and common issue with vw.

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.

The infotainment system no longer works after an over the air update. The backup camera is including all other cameras are no longer visible . Before it completely just stopped working when attempting to back out the infotainment system would freeze and not signal something was back there . The digitally dynamic road display is not working so car acc is not operable . Additionally since the blackout the windshield wipers randomly turn on even if not raining causing distraction and obstructed visibility at times problem has been confirmed by independent vw dealers in several states (there is a whole facebook vw owners group where several people are reporting the same issue) there are also known topics related to these issues on vws help center page regarding ota updates and infotainment system issues it gives instructions on how to troubleshoot but then says see your local dealer if that doesn’t resolve the issue vehicle has been inspected by vw dealer. The backup camera would freeze intermittently and dealer would report nothing to see so it’s working fine . After last ota update system blacked out longer and has not turned back on.

2022 vw Tiguan, VIN [xxx], 54,953 mi. Infotainment screen went black; because the rearview camera image displays only on that screen, the backup camera is completely inoperative in reverse. Failure is constant. I replaced a blown #20 fuse and attempted a hard restart with no result. Xxx, Volkswagen of [xxx] [xxx]: tech found dtc in ecm stating no communication with 5f module (infotainment control unit); vw guided test plan directs replacement of the 5f module. Quoted $501. 54. Dealer stated this is a known issue and multiple customers there are waiting on the same backordered part. Vw has already recalled 2022 Tiguans for this component and this consequence. Campaign 22v-514 ([xxx]): infotainment memory module defect causing rearview camera image not to display, certified by vw as an fmvss 111 noncompliance. Campaign 25v-082: 2022-24 Tiguan camera control unit error, same loss of camera display. Nhtsa VIN lookup on xxx shows no open recalls; my vehicle was included in neither campaign and no remedy has ever been applied. My vehicle has the identical failure (same model year, platform, component, and loss of rear visibility) as the recalled population. The dealer's statement that multiple customers await the same part indicates the defect population extends beyond the recalled vins. I request NHTSA evaluate whether the scope of 22v-514 and 25v-082 was underinclusive and whether a recall query or scope expansion is warranted for uncovered 2022 Tiguans. Ro and VIN lookup available on request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My vehicle was parked on my worksite and when I can out to check a truck in. I noticed my windows looked tinted and when I went to investigate my vehicle was on fire or smoking badly and I closed the door and call [xxx]. This was a very traumatic experience for me considering I had only purchased the vehicle from the dealership on the 18th and had recently been training one of my kids for driving lessons. While I am grateful that me or my family where not physically injured it is unacceptable that both the manufacturer and dealership knowingly put both me and my family in harms way and I expect to be compensated for this preventable traumatic experience we've endured due to no fault of ours.

The back up camera, bluetooth and radio system has all gone black.

2021 Tiguan parking brake comes on without being commanded. There is a fault with the drivers door. I believe the the driver door module or corresponding wiring. The front drivers window toggle switch does not work the toggles switches for the rest of the window work only if the is not an error displayed on the dash. The lock button does not work on the drivers door at all and only works on the rest of the door when an error message is not displayed on the dash. The dash displays the following errors: 1. Driver door contact switch. 2. Start/stop. 3. Electronic parking brake. It also displays attention: engine is running. So far the parking brake only comes on(un commanded) when the vehicle is stopped.

A/c has been a consistent issue since I purchased this from columbia SC- carmax's dealership in 2022. I've replaced the compressor and valves, and no resolve. The car sucks up oil and the electrical system is wacky!.

Following a recent Volkswagen software update, the 5f module on my 2024 vw Tiguan (VIN: [xxx], mileage: 14,449) completely failed. The local dealership (ro number: xxx) confirmed the failure and advised replacing the 5f module (auth code:xxx), which is on backorder with no eta. This initial failure disabled critical safety systems: the backup camera (violating fmvss 111), the sos emergency system, and the tpms. Volkswagen corporate (case with [xxx]) has refused vor escalation and denied alternative transportation. Furthermore, since retrieving the vehicle from the dealership, the electrical issues have escalated severely. The vehicle now experiences intermittent total electrical/lock-out failures 3 to 4 times a day. During these episodes, neither the key fob nor the physical interior lock/unlock buttons function. The vehicle remains completely unresponsive for several minutes before randomly working again. This poses a severe safety risk of trapping occupants inside or leaving them stranded outside. Vw's negligence in addressing these escalating software and electrical safety defects is unacceptable. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On xxx, my 2024 Volkswagen Tiguan experienced an internal electrical failure of the 5f infotainment control module (part #3q5-035-842-j). There were no advance warning lights or symptoms prior to the screen going completely black and unresponsive. The failure was officially diagnosed and confirmed by an authorized dealership, fitzgerald Volkswagen in [xxx], on xxx. The component is currently installed in the vehicle and available for inspection upon request. Safety risk: the 5f module failure completely disables the primary display screen, rendering the rearview camera system frozen and entirely inoperable. This creates a severe rear-visibility safety hazard while reversing, particularly when transporting my minor child, and fails to comply with federal motor vehicle safety standard fmvss no. 111 (rear visibility). Systemic failure & backorder: the module failure also disables the radio, wireless charging, and front/rear usb ports. Fitzgerald vw special-ordered the replacement module under warranty but confirmed the part is on a nationwide backorder with no estimated time of arrival (eta) and approximately 59 units currently backordered nationwide. The vehicle has not been inspected by law enforcement or insurance, but the manufacturer (Volkswagen group of America) has been formally notified under customer care case #xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

According to the report I received from nucar in tilton nh, my 5f module for the infotainment system is not working after an ota update. Navigation, volume, road sign assistance (speed limit signs), bluetooth sound, seat memory, etc . . I had to pay $700 to have them look at the car and they did not fix it. Now my estimate for repair is $1700 . . . This car has 68501 miles . . Just over 60k - this is not an abuse failure - it is a product failure. There are many reports online indicating multiple model years with this issue. I am not sure what this report will do but I hope it supports fixing these expensive cars which break before you can pay them off.

My name is [xxx], and I am writing today to express my complete frustration mentally and financially with a cpo 2021 Volkswagen Tiguan (VIN [xxx]) I purchased xxx. To date my vehicle has been in for service multiple times – countless times for an issue with the infotainment system and driver warning indicators that is still unresolved and again for months waiting on a new engine due to an oil consumption issue that was finally resolved November of 2025 (case xxx). My recent service visit on xxx was due to a “12 v battery not charging” error message. The vehicle was immediately taken to vw of [xxx] where we were advised it would be 3 weeks before my vehicle would even be looked at (which is atrocious) and not to drive it because further damage would be caused with no alternative solution offered for transportation. I then had the vehicle towed to a repair shop where I was advised the alternator “fried a 400-amp fuse and killed the battery, which should not happen, especially on a vehicle that has less than 50,000 miles on the odometer. ” I paid $1,605. 37 for a new alternator, 400-amp fuse and battery. Completely appalling and disappointing considering I take excellent care of my vehicle and it is supposedly an inspected, certified pre-owned vehicle – that’s a lemon in my opinion! I am seeking reimbursement for this huge expense for a vehicle that should not have these issues! I look forward to a resolve to this urgent complaint.

Tiguan purchased 7/3 2026. The sos car info that feeds other instruments did not work. Then the car play communication dropped and would only return after car restarts. Not sure what instruments it ties to but no calls and no sos.

The infotainment mib3 system failed. Infotainment screen is completely black and non functional. This has put my family at risk because I can’t see my backup camera and have very limited visibility through rear view mirror when backing up. I also lost safety features such as rear cross traffic warning, rear auto braking, ability to see pedestrians or vehicles when backing up, and the emergency cell call system. My car also no longer can access navigation or carplay which makes navigation dangerous on my small phone. Failure of mib3 infotainment brain was confirmed by vw dealer. Car is under factory warranty but part is backordered with no eta so I’m forced to drive an unsafe car. Was denied a loaner vehicle. This failure happened 1 day after overhead console spontaneously broke and fell down from headliner. Error lights now persist on the dashboard.

On unusually hot days, my vw Tiguan 2019, pops up a check start system and shuts down the dash and all electrical components (speedometer, a/c, infotainment system, blindside monitors, brake lights etc. ) car still runs but everything does not work. On searching, there are other vw users complaining about this issue as well making it a known manufacturer defect/issue. I called my local vw dealer letting them know that this is a safety issue and to find out if there is currently a recall for this issue but was told there is none. As this is a massively known safety issue. I think the nthsa must mandate Volkswagen to do a complete recall for all vw vehicles they know are affected by this issue on their own budget without having consumers have to pay for this repair. Thank you.

During hot weather the vehicles electrical will shut down while driving displaying a message saying check starter system and I will loose all lighting and brake lights and turn signals and hvac systems and engine will shut off also I was going down the highway when this happened to me and it only happens in hot weather. This has been happening since we purchased the vehicle Volkswagen refuses to fix it and the 2020 models are on recall for this same issues.

The 2026 vw Tiguan infotainment system blacks out due to thermal failure at ambient temps as low as 100 deg f this creates a total loss of driver controls including windshield defrost and demise systems posing an immediate visibility hazard vw refused to repair becuase defective hardware does not store a diagnostic trouble code on reboot. Prevents any driver action to clear fogged windshield. Or operate fan speeds to do so.

Component(s) affected: electrical system: ignition: switch, exterior lighting: brake lights, electrical system: instrument panel summary: when the interior cabin or ambient temperature becomes hot, a critical ignition/electrical failure occurs. The dashboard displays error: "ignition has switched, please safely stop the vehicle. " immediately following, a total electrical shutdown occurs: the instrument cluster goes black, and all external signaling—including the brake lights and turn signals—stops operating. While mechanical engine propulsion is maintained, the driver is left with zero visibility of vehicle metrics and zero exterior signaling to warn trailing traffic. When restarting, the vehicle fails to crank on the first attempt and displays: "check the starter system. " the vehicle functions normally once the cabin cools down or during cold weather. Safety risk & consequences: this defect poses an immediate and severe crash hazard. Operating a moving vehicle without functioning brake lights or turn signals deprives surrounding motorists of critical indicators, drastically increasing the risk of a rear-end collision. Additionally, a complete loss of the instrument cluster impairs the driver’s awareness of vehicle speed and critical safety alerts. Diagnostic & context: an independent certified mechanic diagnosed the issue as a failure of the ignition switch electrical component (not the mechanical tumbler). Thermal expansion causes the electrical contacts to fail, triggering the systemic shutdown. The mechanic noted this part is on a severe nationwide backorder, indicating widespread failure. A known safety recall exists for the vw jetta for an identical thermal ignition switch failure; however, the vw Tiguan—which utilizes the exact same turn-key ignition switch part—is not included. Multiple online automotive forums document identical hot-weather electrical failures among other Tiguan owners, proving this is a systemic hazard that warrants a safety recall.

Keyless system warning continuously goes off. Lane assist continually is unavailable start stop system continually unavailable dealership has serviced the vehicle and warning indicators continue to go off.

Electrical screen fail. Makes backup camera turn black and turns off while using. Off and on repeatedly while in use. Very dangerous.

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.

The contact owns a 2025 Volkswagen Tiguan. The contact stated that while driving approximately 55-60 mph, the vehicle suddenly became inoperable; the power steering became inoperable, and the brake pedal became difficult to depress. The message "no key fob detected" illuminated. The vehicle was taken to the dealer, but the failure could not be duplicated. No repairs were performed. The manufacturer was notified of the failure. The failure mileage was unavailable. The VIN was unavailable.

I was driving in 4 lane town traffic going under 10 mph and the hazard lights came on by themselves, and the car died. Propulsion stopped. Fortunately I was able to pull onto a striped median, and once I was over shock, 3-5 ish minutes, I started the car and drove to the dealership. I don’t remember any warning message, and it seems like the steering and brakes were hard once it was dieing, but I was so shocked it’s hard to remember exactly. This happened in rainy weather, about 65 degrees around [xxx] on [xxx], in bentonville, ar. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My vehicle is experiencing a severe safety hazard where the emergency braking system suddenly slams on the brakes while driving in traffic, pulling into traffic, or backing up. When this happens, the car unexpectedly shuts off, and no warning lights or error messages appear on the dashboard. This has almost caused an accident multiple times, making the vehicle incredibly dangerous to drive. I previously took it to the dealership, but they told me they could not find an issue and advised me to continue driving it while documenting the dates and times it happens on paper. However, I refuse to continue driving this vehicle and put my children's lives at risk just to collect data.

Tha back up camera system is glitching out. We reset the system but is keeps freezing/blacking out after about 30 seconds. This is known issue with this model of Volkswagen.

-after turning the car on and driving a short distance, the driver dashboard made a warning sound and flashed a warning about my 'ignition system' turning itself off. After that, the entire dash (the speedometer, gas gauge, the infotainment system, the internal climate controls, etc. ) went blank. The warning told me to immediately pull the car over and turn it off. Because of this, the car's external brake lights and turn signal indicators also do not work. -because this error is happening while the vehicle is moving and is on the roadway, I am driving blind in traffic without a way to signal lane changes or when I am coming to a stop. -the car has been worked on three separate times (the alternator was replaced twice and the battery once) for this issue, but the issue is still happening. It only happens when the weather gets to be above 80 degrees. -the vehicle was taken to autonation Volkswagen on July 6, 2026, and the service worker who I talked to said he's seen similar issues with Volkswagens in his two and a half years that he's worked in the service department (which lines up with the vw recall for other vehicles) after I described the issue to him. He confirmed those cases also happened when the outside temperatures were high. -no, no warning messages were displayed prior to the issue spontaneously happening back in may 2026. The first warning message I got was accompanied by the dashboard going completely black. -there is a vw safety recall (vw campaign 28h7) and a NHTSA recall (23v604) for the following vw models produced between 2019 - 2020: golf, golf alltrack, golf gti, golf sportswagen, and the jetta in the united states. -vw customer care (called on July 6, 2026) declined to take down my complaint and said they could not enter my VIN to track the error for future recalls because I quote "didn't have a vw customer account. " they provided me with a case number (#07599604) but I'm not sure anything was logged, and I didn't qualify for 'goodwill'.

Since purchasing this new 2025 Volkswagen Tiguan, I have experienced repeated electrical and drivability defects despite multiple repair attempts by an authorized Volkswagen dealership. The vehicle has been out of service approximately 70+ days, including a transmission replacement, a loose ball joint and suspension repairs. Defects include repeated check engine lights, remote start failures, false "door ajar" warnings, intermittent warning messages, vibration while driving, and hard shifting. The vehicle also shut off while I was reversing and had to be shifted into park before it would restart. Before taking the vehicle back, I asked the dealership whether it was safe to drive and did not receive a response. After the vehicle was retrieved from the dealership for the 4th time, several defects recurred within approximately 44 minutes, and the check engine light returned the following night. I believe these recurring defects present a safety risk to me, my passengers, and other motorists.

Out 2026 Tiguan se line the first day when we drove the veh home it had a bad vibration and brake problems hvac system locking up unable to control the fan speed was raining out and the fan speed was inoperative had to pull over due to fogged up windows . The brake system when stopped at a light in traffic it will not hold the veh moves forward while the brake pedal is depressed firmly and in stop and go traffic the brake pedal gets hard . When backing up the the brakes violently apply scares you . The veh had only 384 miles on it the first time in the said they fixed now several weeks later it is back for the same problem . They said they do not know how to fix it .

The contact owns a 2026 Volkswagen Tiguan. The contact stated that while driving, several unknown warning lights illuminated. The contact stated that while the vehicle was at the dealer for a service appointment, the contact was informed of rodent damage under the hood of the vehicle. The contact was informed that the hood insulation, engine cover, plenum seal, and firewall insulation were chewed up by rodents. The contact was informed that the hood insulation, engine cover, plenum seal, and firewall insulation needed to be replaced. The contact stated that the vehicle was garage kept, and there was no indication of rodents on the property. The vehicle was inspected by animal control. The contact was informed that the damage was old. The contact was informed that the damage occurred while the vehicle was on the dealer's lot prior to the contact purchasing the vehicle in may 2026. The manufacturer was contacted by phone, and a case was filed. The failure mileage was approximately 2,809.

The car stopped at a light on a busy street in [xxx] (in the middle lane), then the engine stopped, and my wife could not restart it. I went as fast as possible and met her. I was eventually able to get it started. This is the third time we have had problems like this. I did the same thing for me and another time for my wife. I believe it is the stop-start capability, but I can't say for sure. We have also had bad engine oil burning problems and electrical problems. All of these (I now know, but did not before) are recurring problems for 2019 Tiguans. The cylinder head was rebuilt last year, associated with a similar instance. I am now fully aware that the 2019 Tiguans are known to experience all of these problems, but when I brought my car in on previous occasions, that never got mentioned. I am told xyz is an issue, then billed for repairs. The car was originally leased, and when I purchased it at the end of the lease, I also purchased a full premium warranty. When the issue happened in may of 2025, the policy eventually covered this, but it took over a month of justifications and records before the third-party insurance company agreed to cover the repairs. All of this said, I am no longer comfortable that this car is safe for my wife to drive, as the issues that are repeating are known issues, and yet Volkswagen seems to sweep these under the rug from both a manufacturer and dealership perspective.

While driving on the highway in my 2023 Volkswagen Tiguan (approximately 70,068 miles), the epc warning light and oil warning light illuminated and the vehicle began to stall/lose power. I exited the highway immediately and shut the vehicle down safely. A substantial amount of engine oil leaked from underneath the vehicle after stopping. The vehicle was towed to a Volkswagen dealership. Dealer diagnosis included: * cracked oil pan, * oil separator failure, * and timing chain cover leak. The dealership advised there was no metal contamination found in the oil or filter and no confirmed catastrophic internal engine failure at this time, though the long-term condition of the engine cannot be guaranteed after the oil-loss event. I am submitting this report because the sudden oil-loss event and stalling condition occurred while driving on the highway and created a potential safety hazard.

Vehicle was just turned on and put into reverse. Dash and infotainment center lights flashed and shut off. Vehicle rolled backwards uncontrollably down a sloped driveway. Steering and brakes were not properly functioning. Vehicle came to a stop when it struck a parked vehicle in its path.

The problem occurred immediately after picking my car up from a valet on 5/17/2026 around 9:00pm. The valet had pulled my car up to the front of the seattle park ‘n fly valet by sea-tac airport. I pulled out onto International blvd, and within a few seconds, the accelerator pedal became completely unresponsive. I was able to coast the car into the denny’s parking lot just north of the valet lot (about 0. 2 mi north of the valet). Everything else seemed to work just fine, except for the accelerator pedal (brakes worked just fine). I turned off the engine, and when I tried to restart the car, it was turning over but wouldn’t start. I called out someone to jump the battery, but the battery was fine. We then disconnected and reconnected the battery, and this resolved the issue and I was able to restart the car and drive away. It was dangerous that I was able to pull out onto a road, just to immediately lose any ability to accelerate. I’m lucky there was a nearby parking lot and I didn’t pull into busy traffic. Something seems to have happened at the valet, that was then triggered as soon as I pulled out onto the road. My guess is they tried to start the car and use the twist shifter in some combination that caused a fault that only triggered once I started to get up to speed. It’s strange because they were able to pull my car up to the front of the lot just fine, and I was able to pull out onto the roadway just fine, but the loss of acceleration only happened once I tried to get it up to speed.

Center roof console fell out while driving vw states it out of extended warranty charging $200 for repair I find this very dangerous.

When it is really hot outside 90 and above my car does messes up. As I'm driving my car will throw the code pull over and check starter system. Everything turns off, and then it takes minutes from my car to restart. It has happened multiple times when I'm in traffic at a stop light or driving and it throws the code as my car is moving. I have taken it to shops and still no auto shop can figure out the fix. Happened for the first time a year ago, and now its happening constantly.
