2021 Tesla Model Y: loss of power steering

Filed Oct 29, 2026 · Driver assistance, Electrical · CA

On XXX (4:59 PM and 5:47 PM) and XXX (7:49 AM), while driving, my 2021 Tesla Model Y (approx. 41,500 miles) displayed "Steering assist reduced" (UI_a020), each followed within about a minute by "Lane Departure Avoidance unavailable" (APP_w264). [Add if true: The steering felt noticeably heavier when the alert appeared.] The vehicle's 12V system tested healthy in Service Mode (13.32 V, DC-DC output normal). Tesla Service ([XXX]; service SV02F94980) diagnosed an Electronic Power Assisted Steering (EPAS) rack motor control error with limited power output from overheat or overload protection. On XXX, at 41,788 miles, Tesla replaced the steering gear (part 1188832-00-B), along with the front lower compliance and lateral links, and performed an alignment. I paid $4,522.27 out of pocket; Tesla declined goodwill. Losing power steering assist while driving is a safety hazard. The failed rack belongs to the same Mando-manufactured family (XXX) named in recall 25V‑092 and investigation EA24001, which covered only 2023 Model 3 and Model Y. the federal safety agency's complaint database shows a growing number of 2021 Model Y complaints describing the same UI_a020 alert and the same rack replacement, many filed in 2026. I ask the federal safety agency to evaluate whether the defect and remedy should extend to 2021 Model Y vehicles. Invoice attached.

I am filing this complaint regarding a serious front suspension failure involving my 2021 Tesla Model Y. Vehicle Information: •Manufacturer: Tesla, Inc. •Model: Model Y •Model Year: 2021 •VIN: [XXX] •Mileage: 92,515 miles •Tesla Service Inspection Date: XXX •Service Location: Tesla Service Center, [XXX] Description of Safety Defect: My 2021 Tesla Model Y experienced a serious failure involving the front driver’s side lower control arm/lateral link assembly. The inner mounting bolt backed out and the lower control arm detached from its mounting point on the front subframe. The control arm bushing was torn, and the suspension arm became loose, rendering the vehicle unsafe and undrivable. The vehicle was taken to the Tesla Service Center in [XXX], where the issue was documented in the service estimate dated XXX. Tesla proposed replacing the front lower lateral links, front subframe assembly, left front lower compliance link, and right front halfshaft, along with performing a four-wheel alignment. Safety Concerns: I am extremely concerned that a critical suspension mounting bolt could back out and allow the lower control arm to separate from the vehicle’s subframe. A failure of this nature could result in loss of steering control, wheel misalignment, or a serious accident, particularly if it occurs at highway speeds. This is not a routine suspension wear issue. It involves the separation of a critical suspension component that is essential for maintaining vehicle stability and steering control. Potential Related Recalls and Investigation: I requested that Tesla review whether my vehicle is affected by the following recall or investigation references: •the federal safety agency Recall 21V‑835 •the federal safety agency Recall 23V‑235 •the federal safety agency Recall 26V558 •Tesla Service Bulletin SB-26-31-004 •the federal safety agency Investigation PE26006 See more info in attachment.

My 2021 Tesla Model Y developed a steering system/EPAS fault identified in Tesla Service Mode as EPAS3P_a072_motFeedFwdError, along with UI_a020 Steering Assist Reduced. Tesla diagnosed the vehicle as requiring replacement of the steering rack/EPAS assembly. Tesla informed me in writing that the vehicle may experience intermittent or complete loss of electronic steering assistance, that the vehicle is not operating within manufacturer safety specifications, and that Tesla advises against operating the vehicle until the steering rack is replaced. Tesla also confirmed that there is currently no applicable recall or service campaign for my VIN. I am reporting this because failure or loss of electronic power steering assistance presents a significant safety concern, particularly if steering assistance is lost unexpectedly while the vehicle is being operated. Vehicle: 2021 Tesla Model Y VIN: 5YJYGDEE6MF207395 Mileage: approximately 129,281 Tesla diagnostic fault: EPAS3P_a072_motFeedFwdError Related alert: UI_a020 Steering Assist Reduced I request that the federal safety agency review this complaint and determine whether similar steering/EPAS failures are occurring in other Model Y vehicles and whether this represents a broader safety defect.

The electronic power steering (EPAS) system/steering gear malfunctioned. Tesla diagnosed fault code EPAS3P_A072_mot and recommended replacement of the steering gear/rack, part number 1188832-00-B. The vehicle is currently available for inspection upon request. If the steering gear is replaced, I will request that the failed component be retained or otherwise made available for inspection if possible.The vehicle displayed a warning stating “Steering Assist Reduced Steering May Require Increased Effort.” A reduction or loss of electronic power steering assistance could require significantly greater steering effort and could affect the driver's ability to safely maneuver the vehicle, particularly during turns, low-speed maneuvers, or an emergency maneuver. I was concerned that the steering assistance could further deteriorate or fail unexpectedly while driving, putting the driver, passengers, and other road users at risk.The problem was confirmed by a Tesla Service Center. Tesla diagnosed fault code EPAS3P_A072_mot and determined that the steering gear/rack requires replacement. Tesla recommended the replacement of the steering gear part number 1188832-00-B and provided an estimate of approximately $3200.The vehicle was inspected by Tesla technicians at the Tesla Service Center. I specifically asked Tesla to determine whether a pothole impact could have caused the steering rack failure. After inspecting the vehicle, Tesla informed me in writing that its technicians did not observe any signs of impact damage and that Tesla does not believe the pothole incident caused the current steering rack failure. The vehicle has not been inspected by police or insurance representatives. The vehicle displayed the warning message “Steering Assist Reduced / Steering May Require Increased Effort.” The warning first appeared on or about 8-25-26 at approximately 136K miles. I subsequently brought the vehicle to Tesla for diagnosis, where Tesla identified fault code EPAS3P,recommends rep

I own a 2021 Tesla Model Y with approximately 51,300 miles. Beginning in June 2026 I noticed a persistent creaking noise from the front suspension, most audible when accelerating and when turning at low speed. The vehicle had been rear-ended in June 2026 and repaired at a body shop; the noise was reported to the shop at that time and persisted after the repair was completed. On September 2, 2026 I brought the vehicle to a Tesla Service Center for diagnosis. The technician test drove the vehicle, verified the noise, and performed an inspection on a lift. The written findings were that both front upper control arm ball joints were partially seized, both front lateral link bushings were torn, and both front compliance link bushings were torn. Tesla recommended replacement of the front upper control arms, front lower lateral links, and front lower compliance links, quoted at approximately $2,610 at my own expense. Tesla further stated that a four-wheel alignment could not be accurately performed in the vehicle's current condition because of the torn bushings. No crash, fire, or injury has resulted. The vehicle remains in service. I am filing this complaint because these are the same front suspension components identified in the federal safety agency's open investigation into front suspension link separation in Model 3 and Model Y vehicles, and my vehicle falls within the model years under review. The failure is bilateral and occurred with no impact to the front of the vehicle and no off-road or track use. I am concerned that degraded bushings and seized ball joints across all three component types create a risk of link separation and loss of steering control without meaningful warning beyond the creaking noise.

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 the federal safety agency 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 federal safety agency 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.

I am reporting a safety defect involving a severe structural metallic "clank" or "clunk" under the vehicle's chassis during rapid acceleration and sudden braking. This vehicle was previously serviced by Tesla in 2023 for this identical issue (service invoice attached). While the repair initially suppressed the sound, the hazardous clanking noise subsequently returned, persisted for a period, and then went away on its own.The return and subsequent disappearance of the noise suggests that critical suspension or drivetrain components are shifting out of specification under load, binding, or experiencing intermittent mechanical failure. Given the active federal investigation into 2021–2023 Tesla Model Y front lower lateral link separations, I am deeply concerned that the underlying component remains structurally compromised despite the 2023 service. An intermittent or settling defect still poses an imminent safety risk of sudden component separation and total loss of steering control at driving speeds.

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.

Component that failed: Front lower lateral link and compliance link suspension bushings. Failed components were removed by Tesla Service and are no longer available for inspection. Safety risk: Failed suspension bushings directly compromise steering precision, vehicle stability, and handling — particularly at highway speeds. A driver unaware of this failure could experience loss of steering control or unpredictable handling without warning. Confirmed by dealer: Yes. Tesla Florida (Tampa, 11945 North Florida Avenue) confirmed the failure in writing on May 22, 2026. Technician repair notes state: “inspection failed due to worn suspension bushings in the front.” Tesla confirmed this was the first time these original components had ever been serviced. Invoice #[XXX]. Manufacturer inspection: Yes, repaired by Tesla Service Center. Cost: $1,669.58. Warning lamps or prior symptoms: None. No warning lights, no alerts through the Tesla app, and no prior symptoms communicated to the owner. Failure was discovered only because vehicle was brought in for an extended service agreement inspection. Assessment: Original factory suspension bushings completely disintegrated at 56,258 miles on a 2021 Tesla Model Y (VIN: [XXX] ). This is not normal wear — photographic evidence shows full structural disintegration of rubber bushing material. Other Model Y owners may be driving with identical failures without knowledge.

Vehicle experienced front suspension lateral link failure. The links separated from the sub-frame due to improperly secured fasteners. This is the exact defect described in existing recall SB-21-31-003 / the federal safety agency Campaign 21V835000. The existing recall states 'front suspension lateral link fasteners may loosen, allowing the lateral link to separate from the sub-frame.' This vehicle has this identical manufacturing defect but was not included in the recall database. Tesla Service confirmed the links 'fell out' and separated from the sub-frame at approximately 65,000 miles. Technician notes indicate a 'speed mismatch between wheel and motor' caused by the link separation - this is the symptom of the underlying fastener defect. The failure resulted in loss of steering control and made the vehicle undriveable (VOR - Vehicle Off Road). This is a safety-critical manufacturing defect affecting front suspension, creating crash risk due to sudden loss of vehicle stability and control. Owner is being charged for repair of a known manufacturing defect that should have been covered under the existing recall. This suggests the recall scope was too narrow and did not capture all affected vehicles with this defect. Request investigation into whether recall should be expanded to include additional affected vehicles.

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.
