2022 Volkswagen Tiguan

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.

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 NHTSA. No crash or fire; safety risk is loss of power and oil leakage while in operation.

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.

I was informed from the Volkswagen dealership of where I purchased the vehicle that there are malfunctions with the Lane Assist system and other driver assistance functions caused by a fault in the steering wheel. However, I was also told that Volkswagen no longer manufactures or provides a replacement steering wheel for my vehicle. This leaves me without a viable solution to restore the safety systems that are integral to the vehicle’s operation.

The car will randomly jump, buck, engine accelerate . Even if I brake or put in park when engine on, it still bucks and feels like it wants to accelerate. Also when I want to accelerate and push on gas(like when I stop at stop sign and it’s my turn to go) it will randomly just buck and feels like it wants to stall, in middle of me trying to go into traffic . I’m afraid that if a person walks in front of my car( for example at a light or when I am waiting to turn, breaking, for someone crossing the street in front of my car) the car could bounce jump and hit them even when I break as I said, it jumps even while I break. I also am afraid because when I accelerate into traffic it also sometimes doesn’t accelerate and will pause and bounce….car easily could hit me!! I brought it to vw and they tried to tell me the repair would cost over $3000 I then brought it to another reputable repair shop and they thought it wasn’t related to what vw claimed they would fix. The other repair shop stated it to be computer/electrical issues which causes everything else to malfunction down the line and that they see this in many vw because of the heat here where we live (because vw did not reset computer system before checking electrical code again reason/malfunction. Vw only just went with whatever the computer system said without resetting it. Any ways guess I should also tell you when this happens an exclamation point comes up on dash board with some other initials, which I will send photo of. Iam afraid to drive it is in safe. And sometimes if I turn the car off and back on it’s like nothing is wrong with it!!! And it may not happen again for days !! But always happens eventually. This has been going on for on for about 6 months to 1 yr. Vw always blew me off until my warranty was up and now suddenly it’s an over $3000 issue, suddenly know what the problem is now! My 2nd opinion disagrees with them and told me to bring it to him when it happens but is closed each time it happens😭

Subject: Ongoing Mechanical and Electrical Issues – 2022 VW Tiguan I’m experiencing ongoing issues with my 2022 Volkswagen Tiguan, purchased new and maintained under single ownership. Primary Issue: The vehicle shuts off unexpectedly under various driving conditions—while accelerating on the highway, from a stop at traffic lights, and especially when going uphill or over high bridges. The issue initially occurred once or twice a year around 45,000 miles but has become more frequent. As of 70,000 miles, it now happens on a weekly basis. When this happens, the only way to temporarily resolve the issue is to turn off the vehicle completely and wait approximately 5 minutes before restarting. Recent Maintenance Completed: New car battery (3 battery since purchase of car) New spark plugs (Replaced in June 2025) Regular oil changes (every 3000 miles) New engine air filter and cabin air filter (yearly) Additional Symptoms: The rear-view camera frequently times out or fails to display when reversing. The dealership has not been able to confirm the cause but has mentioned a potential error code P30DE00, suggesting alternator replacement. However, a second opinion found no active error codes, leaving the root cause unclear. I'm seeking a definitive diagnosis and a resolution plan, as the issue has become a safety concern.

I am reaching out regarding ongoing and escalating issues with my 2022 VW Tiguan R-Line Black. Over the past year, I have had to stop at Jiffy Lube multiple times because the oil level kept running low, and they repeatedly topped it off. I found this unusual, given how recently oil changes and services had been performed. This summer, the vehicle began experiencing episodes of stuttering and stalling, accompanied by smoke from the tailpipe. Over Labor Day weekend, after another stall, I brought the car into the VW dealership. They investigated but were unable to identify the cause. Unfortunately, the situation has now worsened. Today alone, the car stalled twice — both times in the middle of traffic. The “check oil level” warning light came on, followed shortly by the “check engine” light. There was also a significant amount of smoke coming from the tailpipe. This is not only a mechanical issue but also a serious safety concern. I have two children, and I am deeply concerned for their lives and safety when driving a vehicle that stalls unpredictably in traffic. At this point, the car feels unsafe and unreliable, and I am unsure how to proceed. Please advise me on next steps regarding potential legal recourse, warranty coverage, or claims I may pursue. Thank you for your guidance. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
