2021 Tesla Model Y: harsh or hard shifting

Filed Oct 20, 2026 · Suspension, Transmission · NJ

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 that the rear knuckles "have play and need to be replaced soon"; they have not been replaced. My car is also in the model years covered by the federal safety agency's XXX preliminary evaluation of front lower lateral link detachment on 2021–2023 Model Y. No crash or injury so far. Confirmed by a service center: Partly, by Tesla Service.XXX ([XXX]): confirmed front suspension noise and replaced both front lower lateral links and compliance links ($1,620.03); the noise continued. XXX [XXX]): verified a rear humming noise and a split rear drive unit bushing. XXX replaced the rear drive unit, verified front vibration on a test drive, and noted the rear knuckle play. XXX: verified front grinding, attributed it to brake wear, and did brake burnishing; no change. SXXX: unable to replicate. I also reported a noise on XXX Inspections: Tesla Service only. No police or insurance involvement. Warning lights: None related to this that I have noticed. I sent Tesla written notice on XXX THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at an undisclosed speed, there was a loud clunking sound coming from the rear driver’s side of the vehicle. There was no warning light illuminated. After the failure had occurred, the mechanic who towed the vehicle informed the contact that the failure could be related to a detached axle. The vehicle was towed to the dealer, where it was diagnosed and determined that the front suspension lateral link had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. After researching, the contact discovered the federal safety agency Campaign Number: 21V835000 (Suspension). The contact expressed concerns that the vehicle should be included in the recall due to the similarities between the reported failure and the recall summary. The approximate failure mileage was 45,483.

Upon arriving home last night with our 3 kids, my wife reported a loud clunking noise coming from the right front wheel area, and said the car felt unstable. After investigation I realized the bolts on the lower control arm have backed almost completely out. I’m very thankful they made it home safe. Any further driving could have been catastrophic.

Two issues: 1) alarming clunking noise coming from suspension. 2) center command screen froze and then crashed completely (black screen) while driving, which resulted in a loss of controls like turn signals and speed indicator.

The car has less than 300 miles on it and I hear a loud clunk under the front of the floor by the pedals as if something is loose like the front motor or the suspension.

Clunk noise coming from front end suspension while driving on the freeway. Then the steering wheel started to go off centered, slightly to the right, and had some play. The steering wheel had to be held tightly to keep car driving straight. I called tesla and took it in to their lake forest service center. The clunk can be felt and heard while turning left onto drive way. Service was able to reproduce noice but was not able to pinpoint the cause. Tech did state that a bolt was 1/8 of a turn loose. Tech performed alignment and state thst noise went away. Service advisor released vehicle and ask to inform him if problem resurface. Same clunk noise persist but at a lower noise level while turning left on driveway.
