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.

It does not accelerate when putting the gas petal all the way down at all or like a boom forward all of sudden. It's random when it's going to do it.

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.

The acceleration of my vehicle has failed several times. The first major incident was when I was driving home across Main St and attempted to go on green as the stoplight changed. Initially, the car jerked and coasted a little bit but after several attempts to press the gas, it still did not go. Shortly after on 04/16/2023, I set up an appointment for my vehicle to be serviced on 05/01/2023 (this was the earliest appointment at the time). I also called Tom Bush Volkswagen in Jacksonville, FL to ensure I was scheduled for the right service and that this wasn't a user error. On 05/01/2023, I took my vehicle to be serviced and picked it up near closing. The technician I spoke to stated there were no issues found and the vehicle is "operating as it is designed to". I asked the technician what should I do in the future because I was sitting at a stop light and the vehicle did not move, even with my foot on the floor. He asked what kind of car I drove before and told me the computerized system in my car took a few minutes to communicate with the rest of my car for it to accelerate. He then proceeded to tell me that if it continues to happen to keep track and maybe get a video of the occurrence. I purchased this car new off the lot in August 2022 and started having this issue around 10000 miles. Yesterday this happened again in the parking lot, causing the car to jerk profusely. I'm afraid this issue will cause me to have an accident before there is a resolution. Both times of these occurrences happened when my minor child was in the vehicle. When this happens I have no control over the acceleration of the car and when it goes. I typically don't move the car for a while after this because I'm afraid it will happen on a busy road. I noticed the car displayed an icon for a while after the most recent incident. I will upload a picture.

Acceleration and shifting at low speeds (below 25mph) is unpredictable. The car will hesitate and then lurch forward in an unpredictable way when reversing up a slope and when starting from a stop, particularly on a hill. The unpredictable nature of the issue, and the tendency of the vehicle to lag and then surge creates a significant safety concern. We took the car to the VW dealer we purchased it from for service. They confirmed there is a problem, and said they have received other complaints. They reset some settings, this did not correct the problem. Since then we have experienced a clunking noise sometimes when the car is shifting gears at low speeds.

When we drive the car the excelarator pedal does respond to moving the vehicle when in heavy traffic and starting off the response is slow the the vehicle jumps forward this has happened since we bought it please let-??s not have another Toyota TPS problem with many people ding before anyone says something.

- Acceleration hesitates from a stop. - If making a left turn or cross traffic turn, when vehicle hesitates it can cause a collision. - Have an appointment 5/20/22 (however VW forums have others reporting the same experience.) - No - No This have been an issue since purchase. From 10miles to the now 3200miles.
