2022 Tesla Model Y acceleration problems

Filed Sep 18, 2026 · Acceleration, Driver assistance · CA

When engaging fsd, you can’t see the safety distance between you and the car in front of you for defensive driving. Even if you are supervising fsd at high speed on the freeway, the high speed and sudden possibility of fsd disengaging is dangerous. The fsd mode should allow for safe distance between you and vehicle in front to be set manually and if it can’t be set manually, it shouldn’t be allowed to following too closely to the front vehicle. It’s unfair and absolutely dangerous to all should the fsd disengage and the driver doesn’t have time to react even though we are responsibly supervising. This feature needs mitigation

While operating a 2022 Tesla Model Y with Full Self-Driving (FSD Supervised) engaged, the vehicle failed to execute a right merge onto the CA-280 North freeway ramp in Redwood City, CA. Instead, FSD initiated an unexpected wrong-way maneuver down a downward off-ramp. As the vehicle headed toward a sharp left curve, it failed to decelerate sufficiently for the turn. The vehicle maintained speed on the downward incline and then accelerated slightly, traveling at around 30 mph immediately prior to impact. Facing an active hazard initiated by the software, I performed an emergency manual override. System steering resistance and abrupt load transfer mid-turn caused an immediate loss of control, driving the vehicle over a mound and into an off-road ditch. Airbags deployed upon impact, and occupants (including a 5-month-old infant) were transported to the emergency room for evaluation. A formal safety complaint is being filed regarding FSD wrong-way navigation failures, failure to decelerate, and severe handling/disengagement instability during emergency takeover scenarios.

The contact’s wife owned a 2022 Tesla Y. The contact stated that while the vehicle was parked, his wife shifted the gear shifter into drive(D), and the vehicle independently accelerated. The Autonomous feature was not engaged. The brake pedal was depressed; however, the vehicle failed to respond as needed, and the front center of the vehicle crashed into a pile of cinder blocks, drove through a gate, and crashed into a dumpster, where it came to a stop. As a result of the impact, the front driver's side tire detached, and the dumpster was damaged. The contact stated that another person helped remove the driver from the vehicle due to the front driver door being unable to open. The air bags deployed as intended. No warning lights were illuminated. The vehicle was towed to a tow yard and was deemed a total loss. A police report was filed. The driver had pain in the back and sought medical attention. The contact's wife was informed of a slight fracture of an unstated bone in her back and ribs, and had to return to the doctor several times for medical assistance. The contact was certain there was no user error to have caused the crash The manufacturer was notified of the failure. The failure mileage was unknown.

I am writing to formally raise a serious concern regarding the functionality of Tesla’s Full Self-Driving (FSD) system. On May 11th, while the vehicle was operating under FSD, I experienced an unexpected disengagement of the system, which then reengaged on its own without any input from me. This erratic behavior caused the vehicle to hit the garage door and resulted in a crash.

On January 9th my wife got into an accident in our 2022 Tesla Model Y vehicle. She reported that as she was backing out of a prking spot in a strip mall, the vrhicle suddenly accelerated backward involuntarely which resulted in colliding with a vehicle which was approaching from the rear side. My wife reported the speed was so violent that she felt dizziness. When she took the car bto the Tesla shop for repair by the insurance, the Tesla repair people discounted her reporting and did not do any follow-up to investigate the issue. Note the onboard camera recorded the swift movement of the vehicle and I will try to upload it. We have read that such problem was looked into by the NTHSA in the past and that it is being revisited again. Note that that Tesla has determined the vehicle as being totalled and has kept it at their shop. Please let us know your thoughts on this matter so if this is a serious problem that it can be addressed so it won't happen to others. My wif was lucky she didn't get hurt and also she didn''t heart others. Please note I am currently traveling out of the country and will be be back in the US on March 12, 2026. You can contact me via my email or I will be available for phone conversation on the indicated date. Also please note I could not upload the recording of the on board camera because of the format incompatibility. THe phone number included is my wife's and please feel free to contact her.

In 9/2025 I noticed that the vehicle software was defaulting to a speed limit of 55 mph. I noticed that when in any form of autopilot and FSD it would accelerate to that speed. This happens in any situation before the car encounters a sign or an area that it's internal map corrects it, which is not common outside of major routes in Idaho. This includes paved marked roads, graded roads, single track dirt roads, my driveway and garage. Sometimes the car controls it's speed consistent with conditions, sometimes not. It can happen unexpectedly, and that's the issue. Where I have learned this is a problem, I of course turn off the AP or FSD and drive myself, however, if I am in driver assist mode and things are going well and the speed limit in the vehicle changes suddenly to the default 55 mph, it can take a moment for me to react. In October 2025 I reported this to my Tesla Service center as well as Tesla's over the air and on line email reporting options (from which I got no response). The service center entered a ticket directly with Tesla, and told me that that Tesla was aware. The explanation that came back was that it was due to a mapping update for the internal map of the car. They said it was the result of Google Maps setting the default speed limit in Idaho, which is where I live, to 55 and that this was due to a September 2025 update. They said it might be corrected with the next update, which has not occurred at this point (January 2026). This speeding behavior can happen suddenly and unexpectedly and seemingly randomly, and has the potential to injure pedestrians, the driver, and property, not to mention that it is also exceeding by far the legal speed limit. Drivers from other areas that may not be aware of the issue are likely to be caught unaware. There is absolutely no reason for the default speed to be 55, ever. It's unsafe, and unnecessary. It is rare to see a speed limit of 55 at all in Idaho. Most of the roads are above or below that speed limit.

While using cruise control at highway speed, the car suddenly slams on the breaks causing major panic. Oversteering onto incoming traffic and cars following are affected slamming on their breaks to avoid contact. Have contacted Tesla Service Center multiple times addressing the problem (Phantom breaking problem). What they keep on telling me is that there is no fix to the problem at this time. The cruise control intermittently turns off and on by itself with no warning or obstruction. No lamps warning or messages prior to failure. My Tesla 2022 Model Y (Performance) has been inspected at the Tesla Service Center many times, but to no avail problem still exists.

I am reporting a repeated safety defect that happens only in rainy conditions. My 2022 Tesla Model Y repeatedly shows critical safety warnings including “Automatic Emergency Braking unavailable”, traction and stability control disabled, and “Vehicle Hold unavailable”. This has occurred during normal driving in rain every rainy season for 3 years, despite 4 service visits and parts replacement including the inverter. It started when I was pregnant and is now ongoing with my newborn in the car. The system failures happen while driving in normal wet/slippery conditions and greatly increase the risk of a crash. This appears to be a systemic safety defect, not driver error, and Tesla has not fixed it after multiple service attempts. Events & Dates: •First occurrence: Feb/2024 •Service visits: 02/01/2024 1. Verified customer's concern via vehicle log data. Technician reviewed the vehicle's logs and found that the vehicles communication system was faulted. Technician was not able to duplicate the concern at this time. Performed diagnosis and found no issues present at this time. Verified vehicle's communication system is operating as designed at this time. No further repairs are recommended at this time. Recommending customer to continue to monitor situation at this time. 2. Updated vehicle to latest available firmware version per service bulletin. •Most recent occurrence: 01/01/2026 fyi today is the 4th time I’ve indicated this issue , and this is during my pregnancy again, I feel extremely stressed and helpless

On [XXX], while using Full Self-Driving (FSD) to drive to a hospital in Oak Park, Illinois, the vehicle experienced sudden unintended acceleration during the disengagement of FSD. As the vehicle approached the hospital area, I initiated disengagement of FSD to manually enter the parking area. During—or immediately after—the disengagement, the vehicle suddenly accelerated at full power without warning, causing an immediate loss of control and a collision with a nearby fixed structure. No system warnings or alerts were issued prior to the event, and the acceleration was so abrupt that manual intervention was not possible. This occurred in a low-speed, street-level environment where no acceleration was intended or expected and does not correspond to any normal driver input. Based on review of preliminary incident data provided by Tesla, there appear to be irregularities during the FSD-to-manual control transition, including missing or invalid input values, gaps in accelerator/brake/steering signals, and speed readings inconsistent with the crash severity. These indicators suggest potential instability in the real-time control system during disengagement. This report is submitted due to concern that sudden unintended acceleration during FSD disengagement may represent a safety defect with potential risk to drivers and the public.
