Tesla Model Y knocking problems

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)

Cut to 1,423 characters — fits with room to spare. Same facts, same careful framing, nothing lost. I'm reporting a recurring suspension/control-arm problem with 2026 Tesla vehicles. My 2026 Tesla developed suspension squeaking. Tesla fixed it under warranty. The same noise is back. While Tesla had my vehicle, they gave me a 2026 Model Y loaner — it makes the same noise. The problem is in multiple 2026 vehicles, not just mine. Tesla Service Bulletin SB-25-31-005 (May 8, 2026) covers rattling/knocking from the suspension on 2025+ Model Y, including front upper-control-arm mounts. Tesla has also documented upper-control-arm ball-joint creaking on Model 3/Y/X from water ingress and corrosion. the federal safety agency recalled 2020 Model Y for improperly secured front upper-control-arm hardware, stating separation could reduce steering ability and increase crash risk. I am not claiming my vehicle has that exact defect. I am asking the federal safety agency to determine whether these recurring symptoms indicate another suspension/control-arm defect. I transport a baby in this vehicle. A control-arm failure causing loss of steering could cause a crash with serious injury or death. Tesla now refuses warranty inspection unless I pay a diagnostic deposit first, even though they fixed the same issue under warranty before and the car is under the 4-year/50,000-mile warranty. I ask the federal safety agency to review this with other Tesla suspension complaints for a defect trend. I can provide VINs, service records, Tesla communications, and noise recordings.

The driver's side lower lateral link assembly and half shaft failed and made the car undrivable. The front driver's side wheel turned in and would not straighten out. My wife drove the car on the highway where she could have seriously injured herself or someone else when the car started to show signs of distress. The Tesla dealer confirmed this problem and fixed the hazard. The car has only 52, 327 miles at the time so Tesla refused to cover the failure. I know this is a known issue and Tesla didn't help with the expense. There was zero warning messages prior to failure. The car started to make a knocking sound in the late afternoon and finally broke down that same night.

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.

In January 2025, my 2023 Tesla Model Y Long Range had approximately 22,000 miles and was only about one year old when a right-front suspension mounting bolt backed out of the front frame/subframe. Before discovering the problem, we heard a popping or knocking sound whenever the steering wheel was turned left or right. Upon inspecting the vehicle, I found that the loosened bolt was dragging across the plastic underbody/skid plate and was close to completely falling out. The photographs show the affected right-front suspension mounting point and bolt. To prevent the suspension connection from separating, I reinstalled and tightened the bolt myself and applied red thread-locking compound. The bolt has remained in place since that repair. However, a major front suspension fastener should not loosen or back out on a nearly new vehicle with only 22,000 miles. I am concerned that if the bolt had completely fallen out while driving, the suspension component could have detached, potentially causing a sudden change in wheel position, steering control, or loss of vehicle control. I am also concerned that the same condition could occur again or could exist on the opposite side of the vehicle. No crash or injury occurred, but this was a serious safety-related suspension failure. I am requesting that the federal safety agency investigate this incident as a possible manufacturing, assembly, or fastener-retention defect.

Model Y (VIN: [XXX]). On XXX, I brought my vehicle to Tesla Service for replacement of the front wheel hub assembly and paid approximately $1,000 for the repair. Shortly after picking up the vehicle, I noticed abnormal knocking and clicking noises while turning the steering wheel. Because I was concerned about the safety of the vehicle, I sought a second opinion from an independent repair facility. On XXX, the independent shop inspected the vehicle and found that two wheel hub mounting bolts had not been properly tightened and that one mounting bolt was completely missing. The repair invoice states that the vehicle was being operated in an unsafe condition and that continued operation could have resulted in wheel hub failure and a serious accident. The shop corrected the condition by replacing the missing bolt and properly tightening the wheel hub assembly. I incurred an additional expense of $284.47, which would not have been necessary had the original repair been completed properly.

I purchased a 2021 Tesla Model Y (VIN: [XXX] ) used directly from Tesla. I am the first retail owner outside of Tesla. I am currently experiencing a knocking noise from the driver side suspension. I have requested that Tesla inspect and complete the following federally mandated safety recalls and service bulletins, none of which appear in my vehicle’s service history: • the federal safety agency Recall 21V‑835 / SB-21-31-003 — Front suspension lateral link fasteners may loosen and separate from the sub-frame, causing instability and crash risk • the federal safety agency Recall 21V‑912 — Suspension knuckles may fracture • SB-20-31-006 — Front upper control arm ball joint reseal Tesla service has refused to perform these repairs free of charge, citing expired warranty (warranty expired April 5, 2025). Tesla’s response does not address that these are federal safety recalls, not warranty repairs. Federal law requires recall repairs to be performed free of charge regardless of warranty status, age, or mileage. Tesla has also failed to provide written documentation confirming whether these recalls were completed prior to selling me the vehicle. Instead, I have been redirected to a self-service VIN lookup tool and a general data privacy request form — neither of which confirms when, where, or whether the recall work was actually performed. I am requesting the federal safety agency investigate Tesla’s failure to complete these safety recalls prior to selling this vehicle to a retail customer, and their refusal to honor federal recall obligations.

Service Concern — Front Suspension / Rattling Noise Vehicle is experiencing a persistent rattling/knocking noise from the front area when driving over bumps, uneven pavement, or rough roads. Noise is noticeable at low to moderate speeds and appears suspension-related. Condition seems consistent with known Tesla Model Y service concerns regarding: * front upper control arm mounts, * front damper assemblies, * and wiper bracket pencil braces. Requesting inspection and evaluation of: * front suspension components, * damper assemblies, * upper control arm mounts, * and any applicable Tesla Service Bulletins related to front-end NVH/rattling concerns. Noise has become increasingly noticeable during normal driving conditions and is affecting ride quality. Please document findings and advise whether repairs are covered under warranty. The symptoms typically include: * Rattling noise over small bumps * Knocking or clunking from the front suspension * Noise on rough pavement, speed bumps, or uneven roads * Sometimes vibration or looseness felt near the dashboard/firewall area The repair procedure mentioned is consistent with a Tesla internal service approach for addressing front-end NVH issues (Noise, Vibration, Harshness). Here’s what each item means: Front Upper Control Arm Mounts These are suspension mounting components near the top of the front wheel assembly. If worn, loose, or improperly isolated, they can create: * Metallic knocking * Clicking during suspension travel * Vibration transferred into the cabin Replacing them helps stabilize suspension movement. Front Damper Assemblies The dampers (shock absorbers/struts) control suspension rebound and compression. Faulty or noisy dampers can produce: * Hollow clunks * Rattles over expansion joints * Repetitive knocking on rough roads Replacing the assemblies usually resolves internal damper noise. Wiper Bracket “Pencil Braces” These braces sit beneath the cowl/wiper assembly area. On some vehicles they c

While making a normal right turn at low speed in a residential neighborhood, I heard knocking sounds from inside the vehicle and immediately lost steering control. I had to physically force the wheel back into position to regain control of the car. After the initial incident, every right turn and brake application produced a loud rubber grinding sound accompanied by significant loss of steering control. The vehicle was completely unsafe to drive. Tesla previously issued recall SB-22-31-002 for 2023 Model Y vehicles for improperly torqued front lower lateral link fasteners at the factory which are the exact same components that failed on my vehicle. Tesla confirmed my VIN was not included in the recall. The vehicle has been driven normally with no accidents or abuse. Mileage at time of failure was approximately 58,000 miles.
