2022 Volkswagen Tiguan

The vehicle intermittently fails to accelerate normally from a stop, especially in hot weather and when the A/C is running. When pressing the accelerator, the vehicle can hesitate for an extended period before moving. In a recent incident recorded on video (reference attachment), I pressed the accelerator and the vehicle failed to respond normally for more than 10 seconds, requiring me to pull over. This creates a serious safety risk when entering intersections, making U-turns, crossing traffic, or pulling into traffic, because the vehicle does not respond when acceleration is needed. The issue is intermittent and more frequent and severe during summer temperatures, when the AC is running continuously. The concern has been reported to the Volkswagen dealer multiple times. Dealer repair attempts were made in 2025, but the issue still exists. An independent mechanic also inspected/tested the vehicle and confirmed there is an issue, but advised that it likely requires Volkswagen-specific diagnosis, software, adaptation, or calibration. No consistent warning light appears before the hesitation occurs. The vehicle is available for inspection upon request. I have video evidence showing the delayed acceleration condition.

I have a 2022 Tiguan 2.0L gas engine with a 10yr 120k mile Volkswagen warranty and all previous maintenance and services performed by the Volkswagen dealer. Just over 40k miles and a check engine light comes on so I go to the dealer. The oil separator, an emissions device, failed and needs to be replaced with the oil pan and timing chain cover. This separator is not noted anywhere on the manufacturer service schedule but based on talking to the dealership and my own research its is a known issue failing frequently over the last 5-6 years with Volkswagen redesigning parts several times in failed attempts to correct the issue but, to date, they have not issued a recall. As such, owners are having to pay significant repair bills as Volkswagen refuses to repair this under emission control or extended warranty coverage.

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 NHTSA investigate whether these recurring failures indicate a broader safety defect requiring corrective action. Currently car is back to dealership for repair again

Oil Change and Check Engine Light continuously appear. Have gotten oil changes during the prescribed timings and still after being within the timeframe of the oil change the sensor appears. The car has stalled while driving due to this and have on multiple occasions have had to buy oil to add to the vehicle even after getting a oil change at a dealership.

My 2022 Volkswagen Tiguan (VIN: [XXX] ) is experiencing excessive engine oil consumption. The vehicle requires oil replenishment every less than 1,000 miles, which is far beyond what any reasonable consumer would expect from a properly functioning engine. I reported this issue to the Volkswagen dealership while the vehicle was still under the manufacturer’s warranty. The dealership stated that this level of oil consumption is “normal” and only added oil without performing any diagnostic testing or repairs. No repair order documenting a defect was issued, and no corrective action was taken. This problem is consistent with the known defect in the EA888 2.0L TSI engine, specifically the defective piston rings that fail to create a proper seal, allowing oil to leak into the combustion chamber and burn off during operation. A class action lawsuit has been filed against Volkswagen regarding this exact defect in 2022–2023 Tiguan models. The excessive oil consumption poses a serious safety risk. If oil levels drop critically low without warning, the engine could suffer catastrophic failure, stall unexpectedly, or overheat while driving — all of which significantly increase the risk of a crash. Despite this being a warranty-covered vehicle and a known manufacturing defect, Volkswagen and its authorized dealership have refused to repair the issue or acknowledge it as a defect. I am requesting that NHTSA open a formal investigation into this matter and consider a safety recall for all affected 2022–2023 Volkswagen Tiguan vehicles.

2022 Volkswagen Tiguan SE, ~70,000 miles. The vehicle experienced a cylinder head failure in the EA888 2.0L TSI engine, causing the check-engine light to illuminate. The cylinder head developed internal cracks, resulting in excessive oil consumption over a period of more than one year prior to the current repair. During multiple service visits to the authorized VW dealership over the past year or more, I reported abnormal oil consumption and expressed concern about a possible engine problem. On each occasion I was told no fault was found. On at least one visit I was discouraged from requesting a deeper diagnostic by being told it would require a significant out-of-pocket fee, despite the vehicle being under the manufacturer's warranty. The vehicle was dropped off for the current repair on [DATE] after the check-engine light came on. The dealership confirmed the cylinder head failure is covered under Volkswagen's New Vehicle Limited Warranty. However, the required cylinder head part has been on backorder for over 60 days with no confirmed ETA. No loaner or rental vehicle has been provided despite the extraordinary duration of the repair. The dealership's own service advisor stated that in the state of Texas alone, approximately 7,000 cylinder heads are currently pending replacement across Volkswagen vehicles — indicating this is a widespread, systemic defect actively being managed within the dealer network, not an isolated incident. The dealership has also proposed that I bear 50% of the repair cost, despite the vehicle being under warranty and having a complete and consistent maintenance record. This cost-sharing proposal was framed as a courtesy, which I do not accept. I own a second 2022 Volkswagen Tiguan SE with the same engine and model year, which I am also concerned may be affected by the same defect. Public records, owner forums, NHTSA complaint databases, and ongoing class action filings confirm this is a known, widespread issue affecting numerous 2022

The light appears on my dash indicating low oil level frequently between oil changes. I have to add oil to my car every 2-3 weeks. An abundant amount of white smoke comes from the exhaust pipes. I’ve been told it’s burning oil. This could ruin my engine or become catastrophic by fire. I was told it could be something to do with the pistons or cylinder head. Mechanic shops don’t want to/have the ability to work on Volkswagens. The dealership says this is normal. I’m afraid for my children and my safety. This is a major safety issue that needs to be corrected. This is potentially life threatening.

Noticed large amount of oil on driveway. Check engine light came on. Took it to the VW dealer. They advised that there is a recurring problem with 2022 Tiguan, where a premature head gasket failure causes engine and coolant leaks. Requires a cylinder head replacement. Since a large number is affected, there is a 8-10 back order of the part. Also, I was told that VW is repairing the defect under Service Bulletin TSB 15-23-01 or TSB /action 2071245, however they would not honor it in my case since the vehicle has 90000 miles.
