Is the 2021 Tesla Model Y recalled in the UK or Europe?
Recalls issued by the UK's DVSA and through the EU's Safety Gate system that cover this model and build period. European models can differ from U.S. ones, and "years estimated" means the recall gave no build dates, so confirm your own car with your registration or VIN.
UK DVSAUpdate vehicle software to correct TPMS behaviour
Risk: On affected vehicles upon detection of a malfunction with the tyre pressure monitoring system (TPMS) the TPMS tell tale does not persist between drive cycles where the vehicle is off or asleep between the drive cycles. Therefore the driver may not be adequately warned of potential under-inflation of the tyres increasing the risk of a collision.
Fix: Install modified software via an Over the Air (OTA) wireless update.
UK DVSAA loss of low voltage system support may cause the audio subsystem to be unavailable
Risk: On certain vehicles that are running firmware release 2022.8 and that experience a loss of low voltage system support the audio subsystem may become unavailable including the use of eCall functionality.
Fix: Firmware release 2022.12.3 or later reverses the power management process introduced in firmware release 2022.8 and maintains eCall audio functionality.
UK DVSAThe front suspension lateral link may be insufficiently torqued
Risk: The front suspension lateral link may be insufficiently torqued.
Fix: Inspect the connection of both front suspension lateral links to the sub-frame. Replace any related damaged components and ensure correct torque of fastening bolts.
EU Safety GateIncorrectly manufactured steering knuckles may break or become deformed or break and the suspension arms could become detached from them,…Incorrectly manufactured steering knuckles may break or become deformed or break and the suspension arms could become detached from them, resulting in reduced driving stability and loss of control and increasing the risk of an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe lateral control arm of the front suspension is attached to the sub-frame by means of two fasteners.If a fastener gets loose enough or detaches from the sub-frame, this can cause the wheel alignment to change. This cause instability, which could have a negative effect on vehicle control and increase the risk of a collision.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe seat belt mounts may be defective.This could result in increased risk of injury in the event of an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe fastening elements that secure the brake calipers to the stub axles may not have been tightened to the correct torque.As a result, the movement of the wheels can be restricted and subsequently the tyres may lose pressure, increasing the risk of an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown

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…
What failed: Front and rear suspension and drive components; the root cause is not resolved. Since at least June 2025, my 2021 Tesla Model Y Dual Motor (110,864 miles) has made a grinding, clunking and knocking noise, loudest at the front on the driver's side. It now happens on almost every drive, including on the highway, and the car sometimes shakes at speed. The vehicle is available for inspection on request. Safety risk: We drive this car with our young family, including on the highway. I am worried a suspension part could fail and cause loss of control. On XXX Tesla's technician wrote…
This vehicle presents a safety risk because it can lose power unexpectedly while driving in traffic. The 2021 Tesla Model Y Long Range currently displays alert BMS_a074 and will not charge above approximately 32%. This is a recurring high-voltage battery failure. The car has already required two battery replacements under warranty (June 2025 at 90,707 miles and February 2026 at 92,077 miles). Only months after the second replacement, the same issue returned. Tesla Service has quoted $17,550.18 for a fourth battery and has not offered further investigation into the root cause, despite three…
While driving my Tesla on FSD mode, my Tesla had critical error and warn me to take over. My navigation and GPS froze. I did several reboot and power cycle and nothing worked. I reach out to Tesla and they stated that I will need a new computer hardware replacement. My Tesla was working fine until they push the new FSD lite software version 14.1 to Tesla vehicle with an incomparable hardware spec.
On XXX, my 2021 Tesla Model Y displayed a low-voltage warning. Approximately 15 minutes later, the vehicle became completely inoperable and we could not open its doors. Our children's car seats were inside and inaccessible. We were stranded with two young children, ages [XXX].[XXX] and [XXX]. My wife ultimately had to transport the children without their car seats because we could not retrieve them. This loss of vehicle and door access after such limited warning created a serious safety risk. Tesla Roadside Assistance was dismissive, including after escalation to [XXX], who was described as…
On October 1, 2026 at approximately 7:55 PM, I was driving my 2021 Tesla Model Y with Autopilot/driver-assistance engaged. The vehicle struck a fixed support pole of the canopy at my driveway. The pole was stationary, but the vehicle did not avoid it. The collision caused significant damage to the vehicle and canopy/pole. I am concerned that the Tesla driver-assistance system failed to detect and/or respond appropriately to a stationary object while engaged. I am not aware of any warning or intervention that prevented the collision. I preserved the available TeslaCam/USB data and made a…
COMPONENT: The car computer (Tesla HW3 / "Full Self-Driving Computer 3," which houses the Autopilot computer and GPS) failed during a scheduled overnight over-the-air software update from version XXX in early XXX. The update failed to install, and from that point all cameras were black including the backup camera, navigation was frozen, and every driver-assistance feature was unavailable: Autopilot, FSD, automatic emergency braking, forward collision warning, lane keeping, and blind spot monitoring. The failed unit was returned to the owner and is available for inspection. SAFETY RISK: The…
On October 1, 2026, immediately after my 2021 Tesla Model Y installed Tesla software update 2026.32.7, the driver-assist computer entered a continuous boot loop. All eight vehicle cameras went black (confirmed in the vehicle's Service Mode), the rear camera displays 'camera temporarily unavailable,' Autosteer will not engage, and the vehicle shows alert UI_a114 for degraded driving visualization. All camera-dependent driver-assist and safety features are inoperative. The vehicle had zero driver-assist or camera issues before the update. I performed a scroll-wheel reboot, a driver-assist system…
On September 23, 2026, the vehicle was being driven at low speed when the driver experienced sudden and unexpected acceleration. The vehicle rapidly accelerated and a collision occurred. The driver reports that she did not intentionally accelerate the vehicle to this degree. Vehicle data and the Event Data Recorder (EDR) were subsequently obtained. The data records the vehicle accelerating from approximately 0 mph to approximately 35 mph in about four seconds, with the recorded accelerator-pedal-position signal reaching 100%. The EDR does not record brake application before the first crash…
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…
Phantom brake incident today,5/26/26. Traveling 35mph, brakes slammed on for no apparent reason. Seatbelt tightened and my head launched forward. Neck is very strained.
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…
