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)

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.

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)

This stalling issue has occurred three times so far, most recently on [XXX], while exiting [XXX]. Each time, the stall happens when I attempt to accelerate after coming to a complete stop in traffic, at a light, or at a stop sign. When it occurs, the vehicle will not move forward, and multiple rapid warning messages appear on the dashboard. The only way to recover is to shift into Park, power the car off, and then restart the engine. After restarting, the vehicle will usually operate normally, allowing me to continue driving. I brought to VW Dealership Pasadena -- they have been unable to diagnose the cause of stalling! Text from Dealership below! This happened exiting the freeway this is very dangerous. +1 (818) 293-1855: we cleared all codes and going to give the car back to you for now-the recall adhesive needs to cure till end of the day-pick up at 4pm --Ron Hancock Volkswagen Pasadena +1 (818) 293-1855: NO-will have a plan of action and we can discuss --Ron Hancock Volkswagen Pasadena INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

At 49,000 miles, all four spark plugs and ignition coils failed and had to be replaced due to engine stuttering and hesitation during acceleration. The check engine light first appeared as I approached a red light to make a timed left turn at a high-traffic intersection during rush hour. The malfunction caused my vehicle to struggle accelerating through the intersection, putting myself and others at risk. A certified mechanic confirmed the error code indicating faulty spark plugs and coils and replaced all components under warranty. However, the check engine light continued to reappear intermittently-?"sometimes turning off for a week after restarting the engine, other times staying on for extended periods. Despite the initial replacement, the same code concern persisted, and the mechanic replaced the components again under the parts and labor warranty. When the issue continued, I took my vehicle to my regular trusted mechanic, who performed a more in-depth diagnostic. They discovered an excessive and unusual amount of carbon buildup in the fuel injectors, which was likely triggering the engine code and causing drivability issues. This diagnosis resulted in an additional repair expense of nearly $700. The vehicle has not been inspected by the manufacturer, police, or insurance representatives, but the failed components are available for inspection upon request. These issues are unexpected given the vehicle's low mileage, age, and regular maintenance. Total repairs reached nearly $1,300. The hesitation posed a safety risk in traffic and suggests a possible premature system failure. My regular mechanic noted Volkswagen may claim this is -??regular maintenance, -?? though this is not common in similar makes and models like the Tiguan.

Oil leak from PVC malfunction Causing stalling, over heating and a huge amount of oil consumption of vehicle. This poses a safety hazards for consumers who commute more than 25 miles to work, drs appts in rural areas etc. I have purchased well over $300USD in the last month on oil alone, taking away from house hold budgets and maintenance of said vehicle.

An issue occurs intermittently when accelerating from a stop/at low speeds. When pressing the gas pedal, there is approximately a 3-4 second delay before the engine kicks in. Theres is no acceleration during those 3-4 seconds and suddenly, the engine will jolt you forward. This presents a safety issue when pulling out on to a street and this vehicle will not move forward. There have been 2 instances where I have almost gotten hit/involved with road rage due to this issue.

The car has a severe hesitation when accelerating from the stop. This hesitation is dangerous in regard that when you try to accelerate from a stop sign into traffic, the car can sluggishly bog down exposing you to oncoming traffic. The issue is more severe after cold start, but can happen anytime. Has caused me to pull out in front of traffic many times only to bog down and nearly be in an accident.

Vehicle has hesitation during cold acceleration. If vehicle is started, pulled to end of short driveway, then go to accelerate onto road, vehicle hesitates and stumbles at times, not wanting to move properly and safely enter roadway. Tried accelerator pedal position reset and no change. This is a common VW Tiguan issue. No fix for it and dealer does not want to acknowledge that it exists. Simply looking on this site and a quick internet search will confirm it exists and is a common issue. And very well could be a significant safety issue when pulling into traffic. In addition, our tiguan also burns an excessive amount of engine oil with no repairs wanting to be made by VW and now has a p2402 code causing engine light to come on all the time. Numerous troubles that are adding up fast and no help or support from VW and its dealers.

My VW hesitates when I step on the gas during first use. This condition will continue until the vehicle warms up. The hesitation will cause the vehicle to speed up very fast. It-??s a safety risk when I enter traffic, either on a highway or on a local road. That-??s because when I pullout in front of on coming traffic, the vehicle will not get up to speed in a timely matter and then it will speed up very quickly. It will hesitate and jerk back and forth. I-??ve learn now that I can not pull out into traffic until I don-??t see any oncoming traffic. The dealership is unable to repair because they are awaiting on a software update that VW is working on for the vehicle because I-??m not the only one with the problem. No warning lamps or messages. It always happens when the vehicle is first started after sitting for several hours. It first appears a few months after I purchased the vehicle.

Ongoing issues with hesitation when accelerating from a stop. The car will feel like it has no power when pushing on the accelerator it may then jerk into gear and accelerate quickly or what feels like jerking in-between gears.

Cylinder #2 Misfire, Multiple Misfires. Codes P030200 and P030000 after car sat idle for 20 minutes. Dealer unable to recreate issue. Stating -??bad gas-?? because they are unable to figure it out. Taking it to separate dealership for investigation/second opinion. Car is filled at same Shell gas station and has been for the past year. Bad gas is just not true. Several owners experiencing same issue and injector harness is being replaced. Please investigate.

My 2022 VW Tiguan 2.0T has delayed acceleration, hesitation, and often bangs into gear at start up. This issue can easily cause an accident when merging into traffic due the lack of reliable acceleration. I have had the vehicle to the dealer and they have found no problem. However, when pressed about internet reports of such problems with the 8 speed transmission they do acknowledge they have heard similar reports. They note there are no repair solutions from VW.

When the car engine is cold, upon first acceleration, the car hesitates badly and has the tendency to lunge forward. It feels like it may stall. When I say cold, I mean when the engine has cooled down. This does not have to do with outside temperature. It happens when it's warm outside as well and the engine has cooled down. This issue appeared when I first took ownership of the vehicle in July of 2022. This poses a serious injury risk when making turns with oncoming traffic. It hesitates to the point that oncoming traffic may hit my vehicle if there isn't enough room for them to stop in time. The vehicle was inspected by the dealer and they were able to recreate the issue. Unfortunately, they said this is a known issue and they can't do anything about it. Diagnostics did not report any failure codes and the car computer firmware is up to date. I am fearful for my life and whoever is in my vehicle. Please look into this issue. I've done some research and found other VW Tiguan owners who are experiencing the same hesitation and were told by the dealer as well that they can't fix the problem.

The vehicle hesitates and then jerks forward when accelerating from a stop. This symptom is more apparent when the vehicle is cold before it has warmed up. The car is available for inspection if requested. It put my safety and the safety of others at risk because the acceleration is unpredictable. This danger is apparent when trying to slowly pull through a crowded parking lot and the car accelerates abruptly or when you-??re pulling into traffic and the car hesitates in front of oncoming cars. The dealers service department has said they are unable to reproduce the symptoms or they say it is a normal trait for that car. The vehicle has not been inspected by the manufacturer, police, or insurance representative. There is no warning lamp or indicators of system failures for this issue. This issue first appeared approximately 500 miles into ownership.
