2022 Volkswagen Tiguan Engine Problems

Check Engine light illuminated, code: P2402 #07E8 EVAP SYSTEM LEAK DETECTION PUMP CONTROL CIRCUIT HIGH. Checked online and same year, same model have recall for same issue.

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 NHTSA. I request that NHTSA 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.

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)

The contact owns a 2022 Volkswagen Tiguan. The contact stated that while driving approximately 40 MPH, the check engine warning light illuminated. The vehicle was taken to O'Reilly, where an unknown diagnostic result was provided. The vehicle was taken to the used car dealer where it was purchased, and the engine was disassembled. The dealer determined that the cylinder head was cracked. The vehicle was repaired. The contact stated that while driving approximately 25 MPH after the repair, the vehicle stalled in the middle of the roadway. The vehicle was restarted after an extended while; however, the vehicle was bucking while driving. The vehicle was driven to the dealer, where an unknown repair was performed; however, the check engine warning light illuminated, and the vehicle was bucking and making an abnormally loud sound while driving. The vehicle was taken back to the dealer, where it was test-driven, and the failure was duplicated. The dealer informed the contact that the vehicle was repaired; however, the failure persisted while attempting to drive the vehicle out of the dealer's parking lot. The vehicle remained with the dealer. The dealer then advised the contact to inform the insurance company of the failure; however, the insurance company referred the contact back to the dealer because the failure was not caused by a crash. The dealer was advised accordingly and threatened to tow the vehicle at the contact's expense and to charge the contact for vehicle rental if the contact did not return the rental. The contact advised the dealer that the vehicle was not repaired and was unsafe to drive. The vehicle was not repaired. The Volkswagen dealer and manufacturer were not contacted. The failure mileage was approximately 67,000.

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.

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 NHTSA review as potential safety defect, including repair delays amplifying risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Excessive oil consumption caused by the PCV Valve failing. The PCV Valve failed causing pressure build up in the engine which luckily for me only caused the valve stem seals to pop out of position on the exhaust valves. This caused oil to leak into the combustion chambers and burn through the exhaust. In other known cases this failure has caused the oil pan and timing covers to Crack and vehicle will lose its oil all over the roadway. No check engine light came on for me only low oil light every 800 miles starting around the 70,000 mile mark. Dealership determined the cause and failure. Manufacturer determined the cylinder head needed replaced. Dropped car off on Nov. 7 2025 and was given a loaner. Part on backorder. Part came in in February and installed. During test drive the cylinder head failed internal and they had to order the same part again. 6 loaner cars later finally got car back on April 10 2026. Extended warranty covered all but $100 of the $4800 cost.

I had routine oil change. I picked up my car and immediately the red warning light came on. I called garage. They said it was PVC valve for high pressure. I fixed that. This is next routine oil change. Now the accessory bracket seal and oil cooler seal need to be repaired. My car only has 68,340k on it. I see there are many complaints on line about this issue.

PCV failure that requires replacement of Cylinder head.

Due to a faulty PCV valve, the entire engine wiring harness needed to be replaced at 69,000 miles. The valve cover and camshafts were replaced, engine components were reassembled with mandatory bolts and gaskets. Lower timing cover was leaking on the passenger side due to the faulty PCV valve and the Caracole canister and leak detection pump. These were replaced along with the canister due to oil contamination. The EVAP lines were blown out and the N80 valve was replaced. As a result, the vehicle sustained $7,200 in repairs because of the damage to the engine due to the faulty PCV valve.

Vehicle started smoking last September/October (2025) after catching several examples of it on camera, VW says it needs new heads. I’ve been on a “waiting list” ever since. The vehicle continues to get worse, recently the low oil light came on as it burns oil excessively . I’ve called VW and they’ve documented it. I’m concerned because I work out of town - My wife drives this car with our 2 1/2 year old and 5 month old.

My 2022 keeps burning oil and I am having to put a quart to a quart and a half of oil about every 10 days into my car

My vehicle has a known manufacturing defect issue that has already been addressed in a Volkswagen Technical Service Bulletin (TSB) which results in an oil consumption issue with 2022 and 2023 Volkswagen Tiguan models. Vehicle problem was confirmed and repaired once by dealership however same oil consumption issue has happened again that was confirmed by dealership. Dealership presently is unable to repair because necessary replacement parts are unavailable at this time.

This vehicle has burned oil and needed regular additional oil fills between recommended oil change. We have taken the car to Volkswagen Northampton for regular oil changes who have never dealt with the oil leak or burning issue. As a result of this the car now at 64k miles needs a new engine. It has piston issues , timing belt issues, , communication modules between the eco and bmc issues, and cam shaft timing issues. Our mechanic is suggesting a new engine. VW of America will not assist us saying there is nothing they can do.

The contact owns a 2022 Volkswagen Tiguan. The contact stated that while driving on a highway at 60 MPH, the vehicle unintendedly decelerated to 25 MPH. The Electronic Power Control system (EPC) warning light was illuminated, and the message "Max Engine Speed - 3,000 RPM" was displayed. The local dealer was contacted and informed the contact that the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that it was a known failure; however, no assistance was provided. The failure mileage was approximately 58,000.

My vehicles started to consume large quantities of oil. Although VW allows for 1.2 quarts per 1000 miles, putting oil in every 1500-1800 miles is very costly and is probably damaging my engine and increasing emission. The Atlas has the same problem and was the subject of a recall. They did a consumption test for free but said i was at an acceptable level. Driving over 500 miles a week for work is becoming very costly and my warranty period is ending soon.

This vehicle has excessive oil consumption. I purchased it certified pre-owned under the manufacturer warranty still in effect. It had 36,847 mikes in the odometer. Having an issue with a prior 2022 Tiquan I checked the oil at 39,000 mikes, it was 2 quarts low and I added 2 quarts, I checked it at 41,000 again it was low 2 quarts. I took it to the dealer with 41,132 miles and had the perform an oil change at Hoover Volkswagen. Then, I checked the oil at 43,000 it was 2 quarts low and added it , due to the bad customer satisfaction I had with my sale of this vehicle and trade I had I took the vehicle to Jim Ellis Volkswagen of Kennesaw what said to do consumption test. I started the process with 45,111 miles on the odometer . The vehicle has an oil consumption issue.

Upon first cranking the vehicle, vehicle has excessive stuttering while accelerating after driving forward. Occurs after car is parked for 1 hour or more most often. Uphill, downhill, flat all the same. Acceleration causes stuttering for the first few minutes of operations. If you do not disable the start stop feature, prolonged stops at red lights cause the same issue and can lead to serious dangerous pretense for accidents while on the roadway. You have no ability to accelerate out of the way of harm until it smooths out. There is also an intermittent engine light that flashes until engine restart but does not record a DTC code. I suspect foul play in the ECU from VW. They are aware and tracking this issue but offer no solutions. Dealers will not service without DTC code and then it’s not repaired still. This is a severe issue for owners. Issue present for nearly a year now with no resolve.

VW Tiguan lost significant acceleration while driving on the highway. Vehicle check engine light came on. Felt like vehicle was going to stall and decelerated to a below highway required speed. Vehicle was inspected by a VW authorized service center and . Verified GFF found DTC's P0431, P04F0, P24D6, and P2101 were in fault mode. Significant oil leak also occurred. Failed component was crankcase pressure regulator and lower oil pan and gasket (due to increased pressure from failed PCV valve.) This was of great concern as the deceleration was significant while on the highway which could cause potential life threatening accidents.

The car puffs smoke out the tail pipes which leads to needing a new engine installed due to a mid yoke by Volkswagen. This is a common problem amongst 2022 vw that I’ve researched and found
