2023 Volkswagen Tiguan engine problems

Filed Oct 18, 2026 · Electrical, Engine · MD

My 2023 Volkswagen Tiguan has recurring oil consumption and an inoperative infotainment head unit. The engine requires approximately one additional quart of oil every 2,000 miles between oil changes. This requires repeated monitoring and oil additions. The cause of the oil loss or consumption has not been confirmed. The infotainment screen remains black. It briefly lights up or attempts to start, but does not successfully boot and remains unusable. This is a recurring problem. If accurate: The rearview camera image also does not display when reversing, limiting visibility behind the vehicle. The oil consumption was first noticed as soon as we bought the vehicle new, and reported a couple times at the dealership we purchased from, who then stated it was normal. The head unit problem began around 60,000 miles, around 8/2026.

2023 Volkswagen Tiguan, approximately 34,316 miles. While driving on I-26 in South Carolina, the EPC warning and amber warning triangle illuminated. I pulled over and stopped. After approximately 10 minutes, I restarted because I was in an unsafe location. No warnings were displayed after restarting, but approximately five miles later they returned, and I exited the highway. After stopping, extensive engine oil was visible on the rear/underside of the vehicle. I immediately checked the dipstick and no oil was visible. At no time did I observe a low-oil-level or low-oil-pressure warning. An authorized Volkswagen dealer diagnosed a faulty oil separator causing internal engine pressure to build, which caused the oil pan to crack and upper timing cover to leak. The oil separator, oil pan and upper timing cover were replaced under warranty. During approximately two months before the failure, the vehicle had several times briefly displayed “Max engine speed: 3,000 rpm.” The night before the incident, the check-engine light illuminated but was no longer illuminated before the return trip began. The vehicle had received scheduled service, including an oil/filter change, at approximately 29,780 miles, only about 4,500 miles before this failure. My safety concern is the sudden pressure-related engine failure and major oil loss at highway speed, together with no observed oil warning despite no oil being visible on the dipstick immediately after the incident. The servicing dealer has stated that it does not know what causes these oil separators to fail. I am reporting this incident so the federal safety agency can evaluate whether it may represent a broader safety issue.

I am filing a safety complaint regarding my 2023 Volkswagen Tiguan SE R-Line with approximately 54,000 miles. The vehicle experienced a significant engine-related failure involving the oil separator/PCV system. Volkswagen diagnosed a failed oil separator/breather that caused excessive crankcase pressure, resulting in substantial oil expulsion and damage/leaks involving the plastic/composite oil pan and timing-chain cover. Volkswagen also identified oil contamination around engine sensors and a P0341 camshaft-position fault. The vehicle has previously experienced EPC/check-engine warnings and entered limp mode, creating concern about potential loss of power while driving. The dealer’s repair required replacement of the oil separator/PCV system, oil pan, timing-chain cover and associated gaskets, along with cleaning oil from the engine compartment and sensors. The repair estimate was approximately $2,490, later reduced to approximately $2,300. Volkswagen declined my request for goodwill assistance. I am concerned that a failure of the oil separator/PCV system can create excessive crankcase pressure and cause oil to be expelled from the engine, damage other engine components, contaminate sensors, trigger fault codes, and potentially result in reduced engine power or limp mode. Sudden oil loss or loss of engine power can create a serious safety hazard, particularly at highway speeds or in traffic. This vehicle has also experienced recurring alignment problems, requiring three alignments in approximately six months, raising additional concerns about the vehicle’s overall reliability and safety. I request that the federal safety agency investigate whether oil-separator/PCV failures and their resulting oil loss, component damage, sensor faults, and potential loss of power represent a broader safety defect in 2023 Volkswagen Tiguan vehicles.

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.

XXX my Tiguan was serviced at Byers VW and received the recommended 80k maintenance. During this recommended service my vehicle passed the multi-point inspection except tires and brakes. On XXX I contacted your service department because as I was driving to [XXX] my check oil level came on. An appointment was scheduled for Tuesday. After the inspection was completed Tuesday it was determined that the value seal needed to be replaced which was already completed 25k miles prior therefore a request to replace the cylinder head would be sent to my warranty company which is through VW Drive Easy.

Potential safety issue should the engine be affected while driving. The problem has not been reproduced by the dealer. The vehicle has been inspected by the dealer 2x. 1st issue appeared at approx. 33k miles and again at about 35k miles.

23 Tiguan..been having to top off oil every couple thousand miles sometimes up to a quart and they tell me it's within "tolerance" to lose oil. Bad pcv caused leak at timing seal and oil pan, oil everywhere needs extensive cleanup. This consumption has happened consistently since buying the vehicle and am being told with the new pcv installed we have to wait to see if the oil problem continues before we can do a consumption test. There should be no reason to be losing up to a quart every few thousand miles and this should be fully investigated.

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.
