2023 Volkswagen Tiguan Electrical Problems

The vehicle has experienced multiple intermittent electrical and safety-related malfunctions that have become more frequent over time. The most serious issue involves the Automatic Emergency Braking system activating unexpectedly while the vehicle is slowly reversing out of a residential driveway. The brakes suddenly apply with significant force even when there is no visible obstacle behind the vehicle. This causes the vehicle to stop abruptly, jerks all occupants forward, and creates a risk of being struck by other vehicles because the sudden stop is unexpected. The vehicle has also experienced an intermittent engine shutdown while stopped in traffic. While waiting at a stoplight or waiting for another vehicle to reverse, the engine will unexpectedly shut off and a message appears instructing the driver to place the vehicle in Park. This creates a safety hazard because the vehicle cannot continue moving until it is restarted. Additional intermittent electrical issues include the infotainment/navigation screen freezing or glitching, the air conditioning unexpectedly blowing warm or hot humid air instead of cold air, and the horn failing to operate properly. The horn will sometimes not sound at all or will be much quieter than normal, reducing the driver’s ability to warn other motorists or pedestrians in an emergency. These problems occur intermittently and without warning. There are no consistent warning lights prior to the failures other than the message instructing the driver to place the vehicle in Park when the engine shuts off. The unexpected braking, engine shutdown, and horn malfunction create significant safety concerns for the driver, passengers, pedestrians, and other motorists. The cause of these issues is UNKNOWN.

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.

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.

The instrument cluster became blank suddenly and no longer displays any speed, mileage, temperature or any essential information. It is currently available for inspection. This is a safety issue as I don’t have any speedometer reading or any important vehicle information. This issue occurred without warning.

Within 2 minutes into my drive, accelerating from stopped to merging onto a road moving up to about 50mph, the instrument cluster behind the steering wheel (speedometer, fuel gauge, etc) completely turned off and went black for 20 seconds before turning back on. It was only the instrument cluster - the infotainment screen did not turn off. Over the past year or so though, the infotainment center has turned off/reset itself a few times. This is a 3 year old car, nothing like that should be happening and is a serious safety hazard. Researching this online, this appears to be a common issue with 2023 Tiguans, and other years/models.

The wireless phone charger in my 2023 VW Tiguan does not function as intended and consistently fails to charge any phone, regardless of placement, brand, or case. The charging pad repeatedly disconnects, overheats the phone, or never initiates charging at all, making the feature completely unusable. This is a safety concern because it encourages drivers to handle their phones while driving after assuming the vehicle would keep the device charged.

On [XXX], I took this vehicle to Galpin VW for service on the collision warning system which began to malfunction on a daily basis and would spontaneously come on multiple times throughout the day, without any other vehicles in front of me nor around me. The service advisor at this service center, Pedro silva, declared to me and my wife that this vehicle was unsafe to drive and stated that he is in contact with VW and their engineering department which instructed to run additional tests on this vehicle. This vehicle now has been in service for this same issue for 6 days and running, including the previous attempt to fix this same issue at Winn VW earlier in the week, which failed to result in any correction. The Galpin advisor further stated that he can not release the vehicle to us in this condition and must continue working on this serious issue in which we agreed, since we can not accept such a vehicle in this extremely dangerous condition.

Brand new VW Tiguan. The start stop system has failed since a month after I bought it. When I am stopped at a stoplight, stop sign or in traffic, often the vehicle will completely shut off and die. The dash displays a message that says must "manually restart". So then you have to put the car in park and press the engine start button again. This happens every few weeks at random since I've bought the car. I have had it into two different Volkswagen dealerships for a total of four times. Volkswagen has not been able to fix the issue and in fact they say several times it has not even showed a code when they scan it. It's very very concerning that the vehicle computer/scanner isn't even picking up this issue!!! This is a huge safety concern as sometimes when the vehicle dies I am holding up traffic on the freeway or in intersections.

While driving the unit will shutdown and reboot randomly, shutting down all functions. Dealer diagnostic showed no issues with the software or firmware. When using NAV or phone related functions the unit will also shut down randomly and reboot. In some cases , the unit will down and not respond to a hard boot by holding the power button down for 20 seconds. The power to the infotainment could cause the dash to shutdown. No warning or power codes were noted.
