2021 Volkswagen ID.4

My vehicle was in Travel Assist mode (i.e. Adaptive Cruise Control) traveling at around 65 MPH. A vehicle has cut into my lane and I felt that the car wouldn't slow quick enough to avoid a collision. I have applied breaks effectively taking the vehicle into my control and taking the vehicle off Travel Assist mode. When driver takes over by applying the breaks in this scenario, irrespective of how hard the breaks are applied, vehicle suddenly moves faster than expected for first few seconds. I had to apply the break harder than I would have applied if I was driving the car in manual mode to get the car to slow down.The expectation was that the vehicle slows down while applying the breaks. This would have caused a collision if I was not quick to react. There were no warning lights or messages on the dashboard prior to or during this incident. This could be a software issue which probably is conflicting between the breaks travel assist is applying and the breaking that the driver is applying. This has happened multiple time to me and on date mentioned on this my wife had same experience confirming that this is in deed an issue that needs some investigating into before it cause any accident(s).

We’ve been leasing a Volkswagen EV car ID4. And after a recent software update, we got problems as in the following. Intermittently when coming to stop, The vehicle is difficult to stop and Pedal pressure seems low. When we experience concern, the accelerator does not seem to react in the same way. As a result, the car failed to stop at short of stop line. Volkswagen sent us a recall notice of High voltage sudden reset error what promote acceleration failure. But our car has not only acceleration but brake issues more than dozen times in 3weeks. We believe we are in very delicate and dangerous situation. But VW doesn’t provide a substitute vehicle, as Volkswagen view problems as vehicle to be still drivable. I strongly disagree with their view, since we will be in serious danger without secure brake and acceleration.

When driving using adaptive cruise control and my car decelerating using the regenerative braking, applying the brakes turns off the regenerative braking leaving only the friction brakes to slow/stop the car. I have demonstrated this situation to a VW dealer technician, who has confirmed that another 2021 VW ID4 that was in the shop duplicated this behavior. I have experienced this behavior multiple times over the last year. Because one of the systems for decelerating the vehicle is not available during a potentially emergency situation, I believe this is a safety risk. No warning lights or messages are displayed when this occurs. This has not been reported to my insurance company or the police.

Dealer replaced infotainment unit but it continues to blank out, freeze and or restart. Very unsafe as you have to take eyes off road to force a restart, also if front windshield is foggy if infotainment system froze or restarting you are now driving with a fogged up windshield which you can’t see out off. Infotainment buttons do not work properly as they do not react to touch again take eyes off road to see whats happening. Infotainment screen and the other screen in front of driving wheel get very very hot. Only after showing dealer videos and recordings of all these occurrences with screen do they decide to do something about it such as change unit but problems persist. Vehicle rolls back on inclines when on a slight incline. Front end squeaks, VW dealer says is coming from the brakes and it’s normal operation. Stopping distances is increased in cold weather, in cold weather braking distances are longer. Side mirror buttons do not always control/adjust mirrors. Dynamic cornering headlight error/malfunction warning on screen constantly, safety risk. Vehicle cannot charge error (s) pop on screen and charging stops. After multiple tries and after changing to another charging stall, charging is able to resume. Factory celular connectivity drops for days and you have to pull fuse #17 or #19 to reset LTE connection. Vehicle has a lot of shortcomings which render it very very very unsafe.

6/21/22 When I was pulling into a parking lot space, the car suddenly accelerated and the steering wheel turned uncontrollably, I could not stop the car, the brakes didn't respond at all. The car was driving by itself, I couldn't do anything to stop it, until I ran into two parked cars where it finally stopped; thank god no injuries. The car was undriveable, and was towed away, I'll have it inspected by the body shop and see if it can be repaired. This was a terrifying experience not being able to control the car, the car pretty much went into run away mode. I hope this gets reported to VW and an investigate gets conducted to find the root cause it as this could happen again to anybody.

My vehicle's stability control system will activate in error to slow the vehicle when traversing moderate corners at speeds of approximately 25 to 35 mph. When this happens the vehicle experiences no actual loss of traction but the ESC warning light will flash on the dash and the vehicle will cut power and slow the vehicle with pulsing applications of the brakes by 5 to 10 mph. This is an unsafe scenario because I am unable to accelerate during these episodes even if needed and the vehicle slows to a speed well below the normal traffic traveling speed. In long sections of winding road I have had to disable the system to be able to drive normally, without interference in my ability to accelerate, and even then the stability/abs system will activate if I touch the brake pedal at all, still with no true traction loss. I am confident that it is a system failure because it occurs very predictably on certain sections of twisty road. I have experimented and the system will inappropriately activate when I drive 30 mph on the curves but provide no interference when I drive the same section at 40 mph. This issue has been reported by numerous owners on the idtalk.com forum, seeming to be specific to the AWD models, with one owner reporting he was told it is a software related issue with no imeadiate fix after having his car inspected for an extended period of time. I have reported the issue to my local dealer.

The stability control actives inappropriately in low speed corners, slowing the car down because it's activating the brakes. This is a known issue on AWD (dual motor) ID.4 and VW dealers have said VW is aware of it and confirmed it on road testing for multiple owners (see below). I would not call it a major/dire safety issue, but it limits forward momentum, which could be an issue in emergency maneuver, and could cause unintended slowing that may increase risk of rear end collision. It is unknown what effect inappropriate brake application could have in slippery conditions. I am one of the first AWD owners in the USA and started a discussion on the problem: https://www.vwidtalk.com/threads/esc-activating-in-off-ramp.3808/page-4 Subsequently, many AWD owners have noted the same glitch. It is believed to be a software glitch (one of many in this car).

Electronic Stability Control (ESC) is activating frequently and unexpectedly. Happens on dry roads, under normal and safe driving conditions. ESC is felt as braking one or more wheels, and indicator is flashing on instrument cluster. This is not expected behavior under the driving conditions. Actuation is 100% repeatable on the same routes and speeds (typically curving roads or highway on/off-ramps), at varying temperatures (above and below freezing), dry and wet conditions, with stock tires properly inflated, in "B" or "D" mode (and drivetrain set to Comfort or ECO mode). Happens when accelerating, coasting, or brake being applied by driver.

In October, 11 weeks ago, while parallel parking, which I do everyday for work, I reversed back into an empty spot, toggled into Drive to straighten out my car and my car accelerated and hit the car parked in front of me. I kept stomping on the break pedal but it was stiff, I couldn't press it down at all. The break pedal was as if the car was turned off. Even though it has been 11 weeks ago, I will not drive the car because VW has not fixed the problem and I do not feel safe. The body repair has been done. The car remains at the dealership where I bought it and is available for inspection. I could of hit many children because I was parking at an Elementary school when this unintended acceleration coupled with no brakes happened. It is VW's first ever ALL ELECTRIC car and the ID4's have NEVER had a software update. VW says, no technicians or trained mechanics, software would have to be done at dealer and could take all day, no software to download using Wi-Fi, may need bigger battery and no parts available. VW corporate fly out to inspect the car and run reports but they refuse to give me a copy and so does the dealership. VW is taking no responsibility and said the brake peddle was never applied, only the accelerator. I never put my foot on or near the accelerator because I was only inching forward to straighten my wheels out. When the car was put into drive it does not need any gas to move only a few inches forward. My insurance representative tried to run a report but he said there was no information at all on the recorder. He said I shouldn't have towed my car back to the dealer because information may have been erased. There were no warnings or assist to stop the car. This has not just happened to me but to many others as well. I can send documentation for that if you need
