2022 Volkswagen Tiguan

EPC light kicks on which is puts your car in limp mode, which is caused by a cylinder head issue. The EPC limits your car acceleration and speed ability, this is extremely dangerous especially on the highway. It’s been a year & Volkswagen is refusing to take responsibility and offer a recall when it’s an ongoing issue with 2021-2022 Volkswagen Tiguans. The cylinder heads have been on back order for a year. This is an issue I believe that needs a nation wide investigation & recall for customers.

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 am experiencing a serious safety issue with my 2022 Volkswagen Tiguan involving delayed acceleration. The problem occurs intermittently but frequently: when pressing the gas pedal from a complete stop or low-speed situation (such as turning or merging), there is often a 5–10 second delay before the vehicle responds and begins accelerating. During this lag, the engine does not rev, and the vehicle does not move, leaving me and my passengers vulnerable in intersections, while turning into traffic, or merging onto highways. This issue has occurred multiple times since purchase, and has created multiple near-miss situations, including once where I attempted to cross a two-lane road and the vehicle did not move for several seconds after pressing the accelerator. Other drivers had to brake abruptly to avoid collision. I brought the vehicle to an authorized Volkswagen dealer twice. They were unable to replicate the issue and returned the car without repair. The third visit is currently being scheduled. No warning lights or diagnostic codes were present, and the dealer stated they could not reproduce the problem. Volkswagen has not issued a fix to my knowledge. The vehicle has not been inspected by police or insurance. There were no warning lamps or messages at the time of the failures. The issue began within the first few months of ownership and has persisted intermittently for the past several months. I paid $30,000 cash for this vehicle in 2023 and it is still under warranty. This issue presents an ongoing safety hazard and significantly reduces my confidence in the vehicle’s ability to respond in traffic. Based on forums and consumer reports, I have reason to believe this is a known issue affecting multiple VW Tiguan vehicles of the same model year. I am available to provide additional documentation, including a written log of the issue and video evidence upon request. I respectfully urge NHTSA to investigate this matter.

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.

The powertrain control units (engine and/or transmission) exhibit concerning behaviors when accelerating from a stop. The actual vehicle acceleration and propulsive torque does not match driver demanded torque for an extended period of time. The amount of delayed reaction is longer when the vehicle is ‘cold’ meaning that the vehicle has not been running prior to driving for an extended period of time. There is some amount of initial acceleration that allows the vehicle to move into the road but then the propulsive torque seems to go away completely for 3-4 seconds. The torque delivered after this delay is then exponential which is again not matching what the driver is asking for. The unintended torque can put the driver at risk of being in a lane without the ability to accelerate out of danger in time. For the situation of having too high of torque can put the driver in danger of hitting an object because the driver was not planning to accelerate so aggressively. These two behaviors can compound on each other as well. When the driver experiences the too low of drive torque condition, the driver could apply more throttle to correct but this will only make the too high of drive torque condition worse. These behaviors occur after every drive-off from standstill. There is a TSB to help improve this behavior. There are no active faults or warning lamps. Many other owners and dealerships confirmed this same behavior. The occurrence date was set to the date of this complaint but these behaviors have been occurring since date of purchase of vehicle.

The extreme acceleration delayed in responding. It has happened on a few occasions causing me to have to quickly brake the vehicle once it finally responds to avoid hitting any traffic in front of me, but one of the occasions was When I tried to make a left turn in an intersection, I pressed on the accelerator and the car moved forward very slightly then stopped and would not move forward, I attempted to get the car to move as cars were then headed straight towards me and I pressed all the way down on the accelerator, after a few seconds it finally responded and jumped forward just in time for the cars coming towards me not to hit my car. After this I immediately took it into the dealership, they confirmed this was a known issue with the Volkswagen Tiguans as well as some Atlas’ however this was an issue with the computer in the car and they had attempted to fix the issue with an update to the computer but had no success therefore they had no way to resolve the issue and we would just have to take the car back as is. This issue put my life, my kid and my unborn child at risk as it would not move, after the dealership confirmed they knew this was an issue with this particular type of vehicle and saying they had absolutely no fix for it so therefore they would do nothing for us is completely unacceptable and when we bought the car no one informed us of this issues so I am very concerned there are many more individuals facing the same safety risk driving this vehicle and I feel it too unsafe to drive until they have a resolution.

There is a delayed acceleration issues on my brand new car, which have become progressively worse and worse. You press on the gas pedal and it stutters to the point of stalling out. I took it into the dealership to have it evaluated and they told me this is a computer software update that they have no control over. I contacted VW corporate and they told me there is no problem and the customer service person (Dominique H.) laughed at me. There are a lot of reports just like this on the internet. Someone is going to die because of this issue. Please address this ASAP it is a major safety hazard that is going to become catastrophic in the near future.

When engine is cold, the transmission hesitates/stutters and then slams into gear. After a couple of minutes of driving, the issue stops. Turning the auto start/stop off does not have an impact on the hesitation/stuttering. This is a safety issue. Dealership claims they cannot replicate and no issues on computer diagnostics. Issue has been on going since it was purchased.
