2021 TESLA MODEL Y Complaints

My car has had a problem with TACC since the day I bought it. Brakes aggressively in what should be a normal driving situation. For instance, when I pass a semi truck on the interstate with my own lane in front of me, the car will slam on the brakes when it is beside the truck. Highly likely to cause a rear end collision.

Got into the car, put it in drive. Warning something like "steering assist not available". My wife was driving and could not turn the steering wheel. I made a service appointment and they returned an estimate for replacing the "PT SENSOR, HIGH PRESSURE (1510047-00-C)" qty 2 and the "PRESSURE TEMPERATURE SENSOR - LOW PRESSURE(1510048-00D) qty 1 and "WASHER, 1/2, STL ZN,SEAL.(1111739-00-A) qty 1 under warrantee.

Front left wheel of vehicle started pivoting under causing tire to bottom out on inner fender without any prior incident or issues. Inspection revealed one of two bolts missing on the lower lateral control link, which was later found in the driveway. Second bolt was 1/3 loosened. Car was towed to Tesla and they proceeded with repairs to include replacing both sets of lower lateral control links. After looking into this further, we found Tesla service bulletin SB-21-31-003 which issued a recall for this problem for 2019-2021 model Y and 3, however, according to Tesla our vin was not included in this recall. These bolts hold the linkage that secures the wheel to the frame, without which the wheel and tire assembly will likely separate or collapse causing major damage and possible death to any occupants that are traveling at normal highway speeds. The SB refers to a torque inspection for these bolts that “may not have been torqued to internal specifications.” The problem appears to be wider than the recall vin range as this was precisely what occurred on our model Y.

Car will, without warning brake aggressively while in cruise control, without pressure applied to brake. No other factors on road, except cars behind. This occurs frequently when car is driven in autopilot. Car will, without warning accelerate to a high speed without pressure applied to the accelerator. This acceleration is stopped with pressure being immediately applied to brake.

The power steering stopped working. "Error UI_a020: Steering assist reduced," and "Error APP_w264: Lane Departure Avoidance features unavailable" appeared on the screen afterwards. I was driving home when suddenly I was unable to turn the steering wheel more than a quarter turn (even with all my weight and strength). I tried resetting my vehicle and the issue persisted. I also tried getting out of the vehicle, locking it and let it sit but the issue persisted when I got back in. Luckily, I had just entered my neighborhood and managed to get it parked in my driveway. After a couple hours of the vehicle sitting in my driveway, the issue stopped. I took the vehicle to the Tesla Service Center where it was inspected, they informed me this is a known issue with current firmware and an unknown future update will fix the issue.

The contact owns a 2021 Tesla Model Y. The contact stated that on several occasions while driving at various speeds, the steering wheel became stiff and failed to operate as intended. The contact stated that the master warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed that the firmware needed to be updated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 39,000.

While in cruise control, car will randomly suddenly brake without warning or visible obstacle. This has been an ongoing problem ever since buying the vehicle in 2021. Very dangerous as it has happened on the highway. Is startling and causes seat belt locking. I have reported the issue to Tesla and it's apparently a "limitation of software". We usually do not use cruise control in the Tesla because of the dangerous of this, but I decided to try again recently in hopes they had fixed it but to no avail.

driving from Albuquerque NM to Farmington NM, in approximately 1 1/2 hours of driving on hwy 550, 4 lane divided highway, encountered no less than 12 hard shadow breaking events. in all instances there were no vehicles, animals or debris in front of the vehicle. It was a cloudless day, starting around 9am, clear no fog, temperature in the 40's. high risk of being hit if a car was following close behind, incident has been reported to tesla, no inspection. there was no waring prior to all hard shadow breaking events.

When travelling with adaptive speed control enabled the car will suddenly and violently decelerate 30 to 50 MPH below the set speed. This happens frequently and does not appear to correlate with anything specific. Sometimes it happens when passing a large white truck. Sometimes there is no other traffic anywhere near me. At the very least I would like Tesla to give me the option of disabling the "safety" features so the car operates like every other car with adaptive cruse control. This is not just me. Search the internet for Tesla phantom braking and you will find many instances going back years. It seems to be getting worse with each software update.

The contact owns a 2021 Tesla Model Y. The contact stated that after his daughter reversed the vehicle, bolts from the vehicle were discovered in the driveway. Upon inspection, it was discovered that two bolts from the driver's side suspension arm had separated from the vehicle. The vehicle was towed to the local dealer who diagnosed that the bolts needed to be replaced. The vehicle was not yet repaired. The contact was informed about an unknown TSB regarding the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 56,753.
