2021 Tesla Model Y steering problems

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.

On [XXX], between approximately [XXX] and [XXX] AM, I was driving my 2021 Tesla Model Y Long Range (VIN: [XXX]) with Full Self-Driving (Supervised) engaged, software version v14.3 Lite, on the southbound [XXX] frontage road at [XXX]. The road has five lanes in my direction, and only the leftmost lane is a left-turn lane. I was in the third lane from the left, and the navigation route required a left turn onto [XXX] at the upcoming intersection. FSD waited until the last moment to change lanes. The light turned red before it could complete the lane change, and the vehicle stopped straddling two lanes, still not in the left-turn lane. I expected FSD to continue straight and reroute. Instead, when the light turned green, the vehicle cut across the leftmost lane and drove up onto the median, apparently attempting to cross over it to complete the left turn. The other side of the median is oncoming traffic. There were two poles with city signs on the median, and the vehicle struck them. I took over immediately, but the collision had already occurred. No other vehicles or people were involved, and no one was injured. My vehicle sustained severe front-end damage, including a detached front bumper, a deformed left fender, and a shattered windshield. FSD/Autopilot features are no longer functioning. The vehicle did not automatically contact emergency services; I called the police myself. The incident was reported to the police (report #[XXX]) and to my insurance company, Progressive (claim #[XXX]). Tesla has contacted me to investigate. I have preserved the dashcam footage. Prior to this incident, I had also experienced repeated FSD issues after a software update in July 2026, including phantom braking and the vehicle suddenly stopping and freezing at intersections, requiring manual takeover.

Subject: Front suspension failure and wheel detachment — 2021 Tesla Model Y Vehicle: 2021 Tesla Model Y VIN: [XXX] My wife's 2021 Tesla Model Y experienced a serious failure involving the front-right suspension, resulting in the wheel detaching from the vehicle. Following the incident, we observed a disconnected suspension arm at its mounting point and recovered a loose fastener. We understand that another fastener associated with the connection was already missing. We have photographs documenting the detached suspension connection and the recovered fastener. We are concerned that this failure may involve a safety-related defect in the front suspension mounting hardware. We request that the federal safety agency investigate whether this incident is related to recall 21V‑835 / Tesla campaign SB-21-31-003, or any other suspension defect or recall affecting this vehicle. Please review this incident for potential safety implications for other vehicles and determine whether further investigation is warranted. We can provide photographs, the failed hardware, repair records, and additional details about the circumstances of the incident.

On XXX my 2021 Tesla Model Y, VIN [XXX], was taken to Tesla Service in West Covina, California, at 69,097 miles. While turning, a front suspension bolt fell out and the car knocked. Tesla estimate 3000-009-0039917905, service SV02F26AB8, dated XXX, quotes replacement of both front lower lateral links, part 2188341-00-D, and four nylon-patch lateral-link bolts, part 1109912-00-B, plus the front subframe, both front halfshafts, both lower compliance links, the front valance, and the front aero shield. The estimate is $8,237.58 with tax and is marked customer-pay. I have not signed it. This is the same joint as the federal safety agency recall 21V‑835, Tesla SB-21-31-003: the front lower lateral-link fastener can loosen and let the link separate from the subframe. My VIN is not in that campaign. A Tesla manager said a recall letter was mailed to me in XXX, he said I did not bring the car in, and I am therefore liable. I have no such letter. No XXX the federal safety agency campaign covers this 2021 VIN for this bolt. I asked him to provide to proof of that letter. He said he doesn't have proof because he doesnt work in that department but he told me the date and that's his proof. The failed part is the recalled bolt. The estimate does not show that the subframe, both axles, both compliance links, and the fascia were damaged by it. I am reporting this for the open lower-lateral-link investigation, PE26006. The car had a sudden suspension separation while turning, which can cause a loss of control. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle falls within the 2021–2023 Model Y population identified in the federal safety agency Preliminary Evaluation PE26-006. The vehicle is a 2021 Model Y and current mileage is 73,350 miles. I am experiencing progressively worsening front suspension squeaking/creaking when turning the steering wheel in either direction, which can now be heard both inside and outside the vehicle. The vehicle also feels noticeably bouncier than normal. I first noticed a faint creaking sound in July and it has gotten worse over time. So I have concerns regarding the lower lateral-link/control-arm suspension failure. Additionally, I have experienced unusual wear on my tires and alignment issues in the last couple of years. There was also a previous recall from 2021 , 21V‑835 / SB-21-31-003, that involved certain 2020–2021 Model Ys where the front lower lateral-link fasteners could loosen and allow the lateral link to separate from the subframe. the federal safety agency specifically described the potential consequence as changed wheel alignment, instability, and increased crash risk. I have reached out to Tesla about my concerns and they stated there were no open recalls and quoted me for repairs. I have screenshots of the Tesla correspondence if needed. I have an upcoming appointment with Tesla on 9/24/26 for diagnostic testing.

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 am submitting this safety complaint regarding premature suspension failure on my 2021 Tesla Model Y (VIN: [XXX]), specifically concerning the front lower suspension links.During a dealer inspection at a Tesla Service Center on XXX, with 72,758 miles on the odometer, technicians diagnosed that the vehicle’s front lower lateral links and front lower compliance links suffered from severely torn factory air-gap rubber bushings. The degradation of these critical structural components required immediate, full replacement of the entire arm assemblies to ensure safe operational handling, resulting in an out-of-pocket repair quote of $1,976.57 (Tesla Invoice #XXX). A compromised or torn bushing in the lower lateral link assembly compromises structural integrity, increasing the risk of mechanical detachment or fracture while in motion, which poses a severe loss-of-control safety risk at highway speeds. This issue directly correlates to the high failure rates and premature degradation profiles currently being investigated by the Office of Defects Investigation under active the federal safety agency Probe PE26006. I request that this case data point be reviewed as further evidence to transition this active preliminary evaluation into a mandatory, formal safety recall for the protection of all affected owners.

I own a 2021 Tesla Model Y with an HW3 car computer. At approximately 54,000 miles, the vehicle developed intermittent failures of the cameras, GPS/navigation, and cruise control. On two occasions during the same routine drive, about 40 minutes into the trip, the GPS, cameras, and cruise control abruptly stopped functioning at approximately the same location. The first occurrence was about July 7, 2026 at 9:15 AM and the second August 7, 2026 at about 3:15 PM. I made the same trip once between these events without a failure. I had also previously experienced a frightening incident while driving northbound on I-280 approaching the lane division for 19th Avenue in San Francisco using Autopilot. Where my lane widened and a new lane began, the vehicle abruptly attempted to follow the new lane to the right. I had to intervene firmly with the steering wheel to maintain control. I do not know whether this event was related to the later diagnosed computer failure, but report it because of its possible safety significance. Tesla serviced the vehicle in Sunnyvale on August 16, 2026 at 54,565 miles. Tesla's invoice states: “Technician addressed the intermittent loss of GPS, cameras, and cruise control. The car computer had board-side failures and was replaced.” Tesla replaced the HW3 computer with a Hardware 3.2 computer, part 1775000-S0-L. Tesla also found corrosion at the 12V input and replaced the 12V battery. My concern is that the HW3 computer failure was intermittent and simultaneously affected cameras, GPS/navigation, and cruise control. The vehicle operated normally between failures, so a driver could not know when the problem might recur. I ask the federal safety agency to determine whether similar HW3 computer failures are occurring in other 2021 Model Y vehicles.

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.
