2022 Volkswagen Tiguan fuel/propulsion system problems

“I got this car in 2024 and it burns through oil. I am constantly replacing the oil and have had to have the seals replaced a couple of times. Every 200 to 300 miles I have to put oil in it. It’s too new of a car for that. I know a lot of other owners have had issues.”

“My 2022 Volkswagen Tiguan has an ongoing excessive oil consumption problem that began in April 2025 when the low oil warning illuminated. I added approximately one quart of oil and contacted the Volkswagen dealership. The dealership instructed me not to add oil myself if the warning returned and to bring the vehicle in for evaluation. On May 12, 2025, I brought the vehicle to the Volkswagen dealership and an oil consumption test was performed. The problem continued. I returned the vehicle on July 25, 2025, and a second oil consumption test was performed. The dealership subsequently replaced the PCV valve in the engine in an attempt to correct the oil consumption problem. On August 25, 2026, the check oil warning illuminated again, indicating that the problem has continued despite two oil consumption tests and replacement of the PCV valve. The dealership is now requesting that I bring the vehicle back for a third oil consumption test. The vehicle has repeatedly been made available to the Volkswagen dealership for inspection and repair. Each time it is taken in for this problem, the dealership keeps the vehicle for approximately one week, and there has been…”

“What component or system failed or malfunctioned, and is it available for inspection upon request? During a multipoint inspection that was earlier than advised due to multiple dashboard lights engaging, we were told that our car has an oil leak due from the timing covers and lower pan seal. They removed the oil separator and found value stem seals to be out towards the exhaust side creating an oil leak that stemmed from blown timing covers and the lower oil pan seal being the cause of the leak. The oil separator was noted as failed. This car has been brought in for every inspection and continued to have lights on post inspection that we were told regularly that they forgot just to turn off the lights but that the oil had been changed. In fact, our next oil change wasn't due until February 2027. How was your safety or the safety of others put at risk? Our safety has been put at risk driving a car with a substantial oil leak and faulty components that only seem found after we are 8,000 over the warranty. In searching the internet, this oil valve and leak situation is common in 2022 Tiguans enough so that there are multiple threads and articles about it. Has the…”

“I am filing this complaint because my Volkswagen Tiguan has a serious and ongoing engine issue involving excessive oil consumption and a faulty cylinder head. The vehicle burns through an abnormal amount of oil between changes, requiring constant top‑offs, sometimes as frequently as every few hundred miles. Despite regularly adding oil and following all manufacturer‑recommended maintenance, the issue continues to worsen. The dealership has confirmed that the cylinder head is defective, which is causing the engine to consume oil at an extremely accelerated rate. However, I have been told the replacement cylinder head is on national backorder, and there is currently no estimated timeframe for when the part will be available. This means I am forced to continue driving a vehicle with a known, documented engine defect that can: Lead to engine stalling Create loss of power while driving Increase the risk of engine seizure Potentially cause a safety hazard on the road Additionally, being required to constantly add oil just to keep the vehicle operable is not only unsafe but financially unreasonable. The problem remains unresolved despite multiple service visits,…”

“The cylinder head has passages that collect carbon build up that build up outside of general maintenance that clog the cylinder head and can eventually lead to combustion failure. This car has been taken to an independent, reputable mechanic in the area, as well as now the dealer. Dealer has confirmed they have at least 4 other vehicles currently with the same issue in just this one location, and parts replacement to remedy the issue (new cylinder heads) are on back order (over 2500 on order in US). This car has been caught early, before this engine failure, as the check engine light first came up and multiple rounds of mechanic checking and trying to fix have lead to this conclusion. Car at this time has not failed in a safety situation, but has the potential to if not remedied, by engine failing while driving. Engine has been inspected by mechanic, and is currently being inspected by manufacturer. Error code was presented once reading the module, and check engine light is visible to prompt servicing the car (code for emissions)”

“5 complaints about oil consumption, 3 check engine lights where had to pull over due to car not running properly. Vehicle putters upon acceleration. Replaced leak detection pump, intake and exhaust system stem seals, oil separator, auxiliary bracket and seal and EVAP sensor.”
