2021 Tesla Model Y Steering Problems

Both torn bushing and broken links at 29k miles.

The car suddenly reduced lane assistance and steering assistance functionality. After calling Tesla they said it is not a software issue. I checked the service mode and it indicated a malfunction in the steering assist motor, which apparently costs $3500 to replace. Online, I have found many complaints about this problem that are not resolved by software updates. In addition, there was a large number used steering assist motors for sale online which indicates a more wide spread problem. This is not normal for cars to have this failure prematurely and is a serious safety hazard. I read online that some had their steering EPAS get locked while driving on the highway and nearly destroyed their Teslas

Lower front control arms are bad. Was told by tire company they need replaced. Quote about 2k

On Monday 12/29/2025, while driving my 2021 Tesla Model Y on the highway at approximately 70 mph returning from DTW Airport to my home with my children in the vehicle, the steering suddenly locked / the steering wheel would not turn. I was able to pull over to the shoulder. There were no warning lamps or warning messages displayed before or during the failure. After pulling over, I powered the vehicle off and back on. The steering partially worked again, and I was able to drive home. Later the same day at my friend’s house/driveway, the steering locked out again and this time it was completely locked, making the vehicle not safely drivable. Again, there were no warning messages or symptoms prior to the lockout. Tesla Service provided a written estimate documenting the complaint “steering locked out / cannot drive” and proposed replacing the steering gear/steering rack (“Steering Gear LHD,” part number 1188832-00-B) plus alignment, total about $3,127.70, at 96,042 miles. The vehicle and component are available for inspection upon request (Tesla can retain the replaced part). This is a safety defect concern because sudden loss of steering control on a highway without warning could lead to a crash, especially with passengers/children in the vehicle.

Received a notice that steering assist may be reduced. Other model year Ys have been recalled due to the same issue. It doesn’t make sense that this should fail in a vehicle that is 5 years old with no accidents and low mileage. This is a safety issue due to manufacturing defect and should be covered under warranty.

Getting message on screen since october 2025. That time total milage on my car was less then 30,000 STEERING ASSIST REDUCED and LANE DEPARTURE AVOIDANCE FEATURE UNAVAILABLE. I did reset / restart the vehicle / soft / hard reset, software update. and This both message got disappear and then again after sometimes its keep coming back. So i did appointment to rocklin tesla center and they gave me cost estimate $5770. Thats way too much so i decline but they said those message might keep popping up because of LOW VOLTAGE DISTRIBUTION AND CONTROLLERS. So i accepted that service and paid $359.68. But i am still getting same both messages on my tesla screen. Sometimes it does comes and sometimes it does not. I did online research and people with same problem stating that because of TESLA's poor manufacturing steering wheel and some kind of faulty circuit board causing this issue. My car never been to any accident and its very low on milage. Please look for other tesla owner who has same problem and tesla has to fix this problem without charging this much amount. Thanks

I’ve had to replace the steering rack, upper and lower control arm for the left wheel, entire computer motherboard. I drove the car for less than 70k miles and zero accidents and zero modifications. Yes I am open for inspection. While driving with fsd lane keep failed causing the car to veer to other lane. The tesla repair shop said the steering rack was sending errors and the whole rack needs to be replaced. They said it was both electrical and mechanical failure. Previously I’ve had the control arms replaced because it was making clicking noise when I turn the wheel. They said it was due to front compliance link and lateral link issues. Also had entire computer board replaced previously. The error message after the incident was lane assist disabled, steering assist reduced. In the maintenance mode it said “ The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects a low voltage (LV) battery undervoltage event.”

My 2021 Tesla Model Y experienced a sudden loss of steering assist, resulting in an extremely heavy steering and loss of steering ability, at highway speed. I needed extreme efforts to push the steering wheel to go off highway to avoid accident. This happened on 6/14/2025 around 3PM. Tesla service diagnosed "internal electrical/mechanical steering rack failure", but no recall was issued for my VIN. I've reviewed NHTSA Recall SB-25-00-004 (2025) for 2023 Model Y involving EPAS/steering assist failure. The symptoms in my car appear identical. I believe the issue may affect more model years than the recall currently covers and request HNTSA investigate further.

Steering assistance reduced alert is showing up on vehicle. It is difficult to drive the car. The car has less than 33,000 miles on it.

The power steering became reduced and diminished while driving. Tesla is stating that there is corrosion on the wiring harness ports on the power steering rack. There was no warning until after the incident, but now a “reduced power steering” annunciation appears in the screen. The Tesla repair station has confirmed the condition.

Upper control arms wear out and start making sounds

The bushing spontaneously separated from the axle/wheel making the car unsafe and undriveable. I cannot believe I am the only one. This needs to be investigated and the car needs to be recalled

When driving on highways the car will jerk the steering wheel and cause the car to turn when the car is in the center of the lane. This causes the driver to counter the force from the steering wheel to keep the car on the road. This only happens when autopilot and full self driving are not being used. I have taken it to the service center twice. The first time they said it was an issue with the car alignment so they realigned the tires and the second time they said it was a problem with the car’s computer so they replaced the computer. This continues to happen and is dangerous. Sometimes it will give a lane departure warning while other times there are no warnings.

My husband was driving the used Tesla we recently purchased from the Tesla dealership. We were driving on the highway with regular traffic and no issues around us. Autopilot was not on (we have never employed this feature). All the sudden, the car quickly jerked to the right on its own and then swerved back on its own. We were driving towards the sun so maybe the camera saw a shadow that wasn't actually there. We think either there is a steering issue or that the car might be reacting erroneously to something that isn't there. Just wanted to report this safety concern because I had my baby in the car and this could have caused a car accident.

Vehicle began making loud creaking noise audible at all speeds, loudest at low speeds. Car was maintained by Tesla dealership. Failure occurred at approximately 52,000 miles, just after 50,000 warranty expired. Diagnosed as failure of both control arms which need to be replaced at significant expense. Failure should not happen on such a low mileage and newer vehicle.

At 59k miles the steering rack failed, warranty expired at 50k miles. This was a $3,000 repair. A number of fellow Tesla owners have encountered this same failure.

while driving on the NJ Turnpike I heard a large "pop" noise. Shortly after as I was on the Exit 7A exit ramp I lost all power steering. I nearly hit the guardrail before the car came to a complete stop. I was able to maneuver the car off the exit ramp and pulled over. The was an error message appeared on the screen indicating "power steering reduced." It wasn't reduced it was non-existent. The car was flat bedded to the Tesla service center and a week later the car repair was completed. The service center indicated it was the "steering rack" broke. Although I don't know exactly what that means, even the service center admitted that this failure should not have occurred. The car is 2 1/2 years old with 90k miles. It is out of warranty so i was responsible for payment. The reason for my complaint is that a catastrophic failure in the steering rack should not happen on a 2 1/2 year old car.

Loss of steering control, frequently accompanied by driver-facing messages indicating that power steering assist is reduced or disabled.

front subframe and both front lateral links came loose due to welded nut not present

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.
