2021 Tesla Model Y steering problems

STEERING

Component Failed: Electronic Power Steering (EPAS) system / Steering Rack. The vehicle is currently displaying the active safety alert code: UI_a020 ("Steering assist reduced / disabled"). The vehicle is available for inspection. Safety Risk: A sudden loss of primary power steering assist creates a severe safety hazard, requiring extreme physical effort to steer the vehicle. This increases the risk of a crash during sudden maneuvers or at low speeds. Confirmation & Warning Lamps: The UI_a020 warning message is actively displayed on the vehicle's touchscreen. Tesla service has remotely acknowledged the alert code and required a diagnostic fee approval via the mobile app. Inspection Status: The vehicle has not yet been physically inspected. Due to severe service backlogs, the earliest available appointment Tesla could provide is more than a month away, on September 30th. I am forced to either park the vehicle or drive it with a known, I think there's active steering system fault until that date.

SAFETY DEFECT REPORT: UNMAPPED RECALL EXPANSION / COMPONENT COMMONALITY My 2021 Tesla Model Y experienced a sudden, dangerous loss of electronic power-assisted steering (EPAS) while driving, instantly displaying the alert: "Steering assist reduced / Steering may require increased effort."An official diagnosis by Tesla Service (Estimate #3000-009-0038060635, attached) confirmed a catastrophic failure of the steering gear assembly, requiring a full replacement of the unit. The specific component listed for replacement is STEERING GEAR - LEFT HAND DRIVE, Part Number: 1188832-00-B. This is the identical engineering architecture and part family (1188832) targeted in NHTSA Safety Recall 25V092 for an overvoltage breakdown of the internal EPAS printed circuit board. While my vehicle falls outside the current 2023 model year production window defined by Tesla for 25V092, it uses the exact same component architecture and suffered the exact same failure mode. This represents a clear pattern of failure and component commonality expanding into earlier model years (2021). I am submitting my official itemized Tesla repair estimate of $3,072.50 as physical documentation. I request that the NHTSA review this component match and investigate an expansion of Recall 25V092 to protect other owners of earlier model years from this sudden loss of steering control.

Component: Suspension: Front — lower lateral and compliance link assemblies; missing and backed-out lateral-link-to-subframe fasteners; torn bushings Beginning in XXX, the vehicle produced a reproducible knocking noise from the front end when reversing and turning at parking-lot speeds, with no dashboard warnings. Tesla Service ([XXX], invoice XXX) verified the noise and documented on the invoice that the cause was: 1. A front left lateral-link-to-subframe mounting bolt MISSING entirely; 2. A second lateral-link fastener significantly backed out; 3. Torn bushings in both front lower compliance links. The technician replaced both front lower lateral link assemblies and both front lower compliance link assemblies with new hardware (invoice line items: XXX lateral links; XXX and XXX compliance links). Total customer cost for the suspension work: $1,539, out of warranty; goodwill and defect coverage were denied in writing as "wear and tear." A structural fastener missing entirely from a primary front suspension link is not ordinary wear. It is the precursor condition to the lateral-link separation investigated under PE26006, which covers this vehicle by year and model. With one bolt absent and the second backed out at under 30,000 miles, this vehicle was effectively one fastener away from the detachment event the investigation documents. The contemporaneous torn bushings in both compliance links reinforce premature component failure, not age-related degradation. No crash, fire, or injury occurred, and the vehicle remained drivable. However, the failure occurred without warning on a safety-critical steering and suspension load path.

STEERING

The electronic power assisted steering (EPAS) rack on my 2021 Tesla Model Y experienced an internal electronic failure. The failure first occurred while the vehicle was performing an automated parking maneuver (Autopark) at low speed. The vehicle displayed the warning "Steering assist reduced / Steering may require increased effort" (alert UI_a020_SteeringReduced). Using the vehicle's built-in Service Mode, I retrieved the underlying diagnostic fault: EPAS3P_a072_motFeedFwdError, described by the vehicle as "Motor control feed-forward correlation error," set when the difference between estimated motor torque and commanded torque exceeds 1.2 Nm. The vehicle's own diagnostic screen lists the clear condition for this fault as "Replace EPAS," indicating an internal hardware failure of the primary EPAS module. The listed potential impact is "Reduced steering assist and EAC inhibited." The fault initially cleared after approximately three minutes but returned and is now latched: it persists through vehicle reboots and multiple drive cycles. While the fault is active, power steering assist is reduced and lane keeping assistance / active safety steering features are inoperative. Safety risk: steering assist can degrade without warning during low-speed maneuvers, requiring sudden and substantially increased steering effort, and lane keeping assistance is disabled. The failure occurred while an automated driving feature was in control of the steering, with no curb impact, collision, or abnormal use.

Error ui_a020 "steering assist reduced" appears without any noticeable steering changes at the moment, but with a warning that steering may become increasingly harder and harder. There were recent recalls on other models of Tesla.

The steering is not functioning properly. This is sealed system and no where else I can get it. This a safety issue and I haven't seen any car steering failing like this. Even cars as old as 20 year has no such issues. This is huge slap on of $3k+ on consumer. The cars is hardly 5 year old.

STEERING

A 2021 Tesla Model Y experienced steering/suspension warnings followed shortly by a steering-assist reduction event. On or around May 21, 2026, the vehicle displayed: “Steering alignment service recommended — OK to drive, schedule service soon.” The vehicle was brought to Tesla because the owner was concerned the car had detected a steering, alignment, suspension, or safety-related condition. The Tesla invoice from that visit appears inconsistent. It states that “a wheel alignment check was completed,” but also states “No Labor Performed — Customer Did Not Authorize Repairs or Inspection,” with 0.00 labor hours and no charge. A documented steering/suspension diagnostic inspection, alignment report, alert-log review, or safety assessment was not performed by Tesla or inspected. The owner was advised to replace tires and return later. Approximately 90 miles later, during a low-speed three-point turn, the vehicle made a loud pop/clunk from the front area and displayed: “Steering assist reduced — Steering may require increased effort.” A related alert also stated Lane Departure Avoidance features were unavailable. This created a safety concern because steering effort may unexpectedly increase during low-speed turns or parking maneuvers. Tesla later inspected the vehicle and documented torn front lower lateral/compliance link bushings and vehicle log data showing steering gear alerts. Tesla replaced the front lower lateral links and front lower compliance links and performed alignment work. After those repairs, Tesla stated a steering gear alert was still present and recommended steering gear/steering rack replacement with additional alignment work. The concern is that a steering/alignment warning occurred shortly before the physical front-end failure and reduced steering-assist event, but the earlier Tesla visit does not clearly document that the warning was meaningfully inspected or safety-assessed. Vehicle is currently unsafe to drive and is in Teslas possession

My 2021 Model Y has about 24,500 miles began squeaking when turning the steering wheel or hitting bumps. I read online that many tesla owners had the same issue. The design on these weren't great allowing water to penetrate these parts and cause them to ware down faster. I already paid for the replacement of the upper and lower control arms.

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 was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [XXX] and [XXX] . We were completely trapped in the vehicle with no power. My [XXX] old remembered to use the manual latch to get out. I opened my door manually and It broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [XXX] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

STEERING

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

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.

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.

STEERING

The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

STEERING

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.”

STEERING

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.

STEERING

The vehicle lost steering at 10 mph as a bolt from the front suspension's upper control arm and lateral link fasteners became loose and detached rom the vehicle. The wheel was completely misaligned, and the vehicle was not drivable. The vehicle could not be moved to the side of the road, putting my safety and the safety of other drivers at risk. I fear that this could have been a fatal accident had I been on the highway. This issue has been confirmed by Tesla Service Center, and they acknowledged that this is a known issue. There were no warning indicators or recall notices sent to warn of this known issue. My vehicle should have been recalled. Tesla is making me pay $3,000 for repairs despite knowing this is a manufacturer defect, and they are continuing to put lives at risk by not issuing a wider recall.

STEERING

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

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.

I was driving into a parking lot and heard a loud bang. I get out of my car and see that the metal that connects the tire to the car came down and screws came out. It is not drivable. I know this is not something normal and shouldn't happen. This is very dangerous and I am grateful I wasn't on the freeway when it happened. I was not involved in any collision and i did not hit anything. This simply happened on its own
