2022 Volkswagen Tiguan: sudden loss of power

Filed Aug 18, 2026 · Engine, Transmission · NV

2022 VW Tiguan SE had PCV (positive crankshaft ventilation) also known as air-oil separator failed just outside of warranty creating a pressure cooker like effect in the engine which caused several seals and hoses, (such as the upper/front timing cover gaskets, rear main seal, and valve stem seals) to fail. The oil pan gasket was also destroyed. Although I was fortunate enough to be able to drive from my house around the corner to my local mechanic, this could have become a dangerous scenario considering most of my driving is done on busy freeways -- this could have caused severe oil slicking, sudden loss of power, and/or total engine failure. All of which could have resulted in a fatal, multi-vehicle accident. This appears to be a relatively common incident involving this particular year and model according to a New Jersey federal case ([XXX] et al v. Volkswagen [XXX] et al.), and several other complaints found. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting this complaint regarding my Volkswagen vehicle because it has experienced two recurring defects during the warranty period that remain unresolved despite repeated repair attempts by the dealership. Issue 1 – Excessive Oil Consumption The vehicle has had a persistent excessive oil consumption problem since the warranty period. The dealership has attempted to repair this defect six times, including replacing an engine valve, but the issue continues. The vehicle still consumes excessive oil, requiring frequent monitoring and topping off. This creates a serious safety concern because low engine oil can result in engine damage, sudden loss of engine power, engine seizure, or an increased risk of fire while driving. Issue 2 – Electrical System Failure The vehicle has also experienced ongoing electrical problems involving the keyless entry system, repeated 12V Battery Low warnings, inoperative interior lights, and loss of connectivity with the Volkswagen mobile app. These problems have persisted despite nine repair attempts by the dealership and remain unresolved. The vehicle has spent a significant amount of time at the dealership throughout 2025 and 2026 for these recurring defects. The repeated electrical failures raise significant safety concerns. The keyless entry system can fail to unlock or recognize the key, the low 12V battery warnings indicate an unresolved electrical issue, and the loss of interior lighting reduces visibility inside the vehicle. The repeated failures also raise concerns about the reliability of other critical electrical systems and the possibility of the vehicle failing to start or operating unpredictably. Despite six repair attempts for excessive oil consumption and nine for electrical defects, Volkswagen has been unable to permanently fix these issues. I request the federal safety agency investigate whether these recurring failures indicate a broader safety defect requiring corrective action. Currently car is back to dealership for repair again

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, documentation, and repeated oil consumption tests. This is a safety issue, not just a maintenance concern, because the engine can fail unexpectedly if the oil drops too quickly. I believe this is a significant defect affecting multiple Volkswagen vehicles and should be investigated by the federal safety agency. I request that the federal safety agency open a formal investigation into the excessive oil consumption and cylinder head defects on Volkswagen Tiguans, as owners should not be left with unsafe vehicles due to known manufacturing issues and unavailable critical engine components.

Problem Description: 2022 Volkswagen Tiguan (VIN: [XXX] ) diagnosed with excessive oil consumption and coolant loss requiring cylinder head replacement. Vehicle at dealer since December 6, 2025, part on national backorder, estimated 6-7 more months wait (total downtime already ~1.5 months). Dealer advised retrieving car tomorrow and driving it while monitoring/adding oil and coolant as needed. This is unsafe: low oil risks engine seizure, low coolant risks overheating—either can cause sudden failure, stalling, or power loss while driving, creating crash risk (especially with my child as frequent passenger). Symptoms: frequent low oil warnings, coolant loss, check engine light, white smoke from tailpipe. Appears linked to known EA888 engine issues in recent Tiguans (ongoing class action on oil consumption). Request the federal safety agency review as potential safety defect, including repair delays amplifying risk.

Purchased new; problems began early in ownership and have recurred despite multiple dealer visits. At ~75,995 miles in July 2025, the vehicle developed a significant engine oil leak. Multiple inspections have found the engine oil level low due to leaks from cracks, and the dealer also verified excessive crankcase pressure from a faulty PCV system that forced oil past sealing surfaces. Parts replaced included the PCV/separator, upper timing cover, a related pipe, and the oil filler funnel; DTCs were cleared and the vehicle was returned as “operating to specifications.” Despite these repairs, the vehicle has an ongoing pattern of engine problems, including warning lights and loss of power/limp mode while driving. This creates a safety risk due to sudden power reduction and the possibility of engine damage from oil starvation and continued leakage. I have repair records documenting the July 2025 diagnosis and parts replaced, prior visits showing repeat engine/drivability issues, and notes reflecting low oil observed on multiple inspections. Volkswagen denied assistance and directed me to BBB AUTO LINE; I am refiling with BBB and reporting this safety concern to the federal safety agency. No crash or fire; safety risk is loss of power and oil leakage while in operation.

August 11,2023 went to dealer for oil change and Halodex fluid service at Napleton VW of Springfield, Missouri. Two hours later on drive from Springfield to Dallas, Texas outside Pryor, Oklahoma the following happened: In right hand lane on cruise at 72mph in 65mph, heard clunk in rear. Lost power and car began to slow down. Pulled over and Halodex fluid was spewing from under car. Car would not go into gear and move. Had vehicle towed to closest VW dealer Don Thornton of Tulsa, Oklahoma. Was determined rear differential failed. VW has not offered reason why a 2022 VW Tiguan SEL r-line premium with 49,000 miles approximately had a powertrain failure. In August of last year (12 months ago) we owned a 2017 VW Atlas SEL that had the same issue after an oil change and Halodex fluid service. A clunk was heard and grinding of gears. VW of Wichita, Kansas bought the car from us and put us in the 2022 Tiguan.
