2026 Tesla Model Y Suspension Problems

Brand new car and its widely reported of front suspension noise, particularly with the RWD models. My car is the RWD model and I have the distinct and noticeable front suspension noise at non highway speeds.

I am filing a complaint regarding a suspension defect on my new Tesla Model Y Juniper. Shortly after purchasing the vehicle, I began hearing a distinct knocking / clunking noise coming from the suspension when driving over small road imperfections and at low speeds. The noise is clearly abnormal for a new vehicle and sounds like loose or defective suspension components. I brought the vehicle to a Tesla service center, but the issue has not been resolved. Despite inspection and attempted repairs, the knocking noise continues to occur. This raises serious concerns about the quality and safety of the suspension system. Based on information from other Tesla owners, this appears to be a recurring issue affecting multiple Model Y Juniper vehicles. A persistent suspension defect on a new vehicle may pose a safety risk and should be investigated. I request that NHTSA review this issue and investigate whether there is a manufacturing or design defect affecting the suspension system of the Tesla Model Y Juniper. Vehicle Information: Model: Tesla Model Y (Juniper refresh) 7SAYGDEE9TF559226 Issue: Knocking / clunking noise from suspension Condition: Occurs at low speed and over small road bumps Status: Tesla service attempted repair but the problem persists (left and right front upper control arm replaced) This problem should not exist on a brand-new vehicle and requires proper investigation.

I am submitting this complaint regarding a newly leased 2026 Tesla Model Y Premium RWD, which I took delivery of on February 6, 2026 from Tesla Watertown, MA. I am a returning Tesla customer and entered this lease after test driving the same model on January 24, which did not exhibit any issues. Immediately upon driving the vehicle off the lot (approximately 12 miles), I noticed a persistent rattling noise from the front suspension area. The noise occurs over normal road conditions and has been present since delivery, significantly affecting the quality and value of the vehicle. On February 9, Tesla Watertown evaluated the vehicle and later replaced both front upper control arm (FUCA) mounts. On February 10, before repairs were completed, multiple safety systems suddenly disabled while driving, including regenerative braking behavior, traction and stability control, lane safety features, and automatic emergency braking, creating a dangerous situation. I returned the vehicle immediately and was provided a loaner. I picked up the vehicle on February 13 and was told the suspension issue was resolved, but the noise remained. I then sought a second opinion at Tesla Peabody, where a master technician conducted a ride-along and confirmed the condition. He verified that the latest FUCA parts had been installed and the front structural “pencil braces” had been removed per Tesla guidance. I was informed the vehicle falls into a known noise category affecting 2026 RWD Model Y vehicles and that there is currently no repair or engineering solution available. This defect has existed since delivery and remains unresolved after multiple service visits and component replacements. I have contacted Tesla regional leadership and customer support multiple times without response.

Went for a tire rotation. Service tech noticed the following- THE PASSENGER REAR CONTROL ARM HAD A BOLT THAT WAS BACKING OUT OF IT & THE NUT WAS MISSING. THE BOLT HAD RUBBED THROUGH THE WHEEL WEIGHT ON THE WHEEL THAT WAS ORIGINALLY ON THE RIGHT REAR. Photo is included of the rear control arm bolts for both sides of the car. Only the right rear had a problem.

Front suspension makes knocking and rattling noise - Tesla's solution was to remove structural braces from the car that transmit the noise - the car has not been recertified with the braces removed, I am concerned about adverse safety, especially in small frontal overlap collision.

1. There is a constant thunking noise coming from the front suspension when traveling on slightly bumpy roads at low speeds. 2. Both front seats squeak and squeal as if they are loose and not bolted in correctly. 3. Front brakes screach and squeal when coming to a stop in cold or wet weather, escpecially pronounced during cold weather. (This is an active service bulletin in all vehicles made in their Berlin factory but is happening in U.S. built vehicles as well.

Obviously Tesla accepts the very serious problem that it is presenting in the vast majority of Model Y juniper 2026 specifically in the RWD line, they are making deliveries of these vehicles without having gone through a rigorous quality control that determines that the noise actually exists and that over time they could affect too many components of the suspension and end up compromising the stability of the vehicle, violating road safety issues, it is something unprecedented and absurd that they do not even take the task of checking the cars exhaustively and determining the root failure that this suspension problem implies, it is a noise as if the front shock absorbers did not work and were totally dislocated, out of their normal location.

Since I purchased my 2026 Tesla Model Y RWD, the vehicle has had a persistent mechanical noise and vibration issue coming from the front suspension and brake area. This issue has been ongoing since the first weeks of ownership and has not been repaired or properly diagnosed after multiple service visits. Details -Component/System Failed: Front suspension/brake assembly (unknown exact component; may involve control arms, bushings, or brake rotors). -Availability for Inspection: Yes, the vehicle and recorded videos are available for inspection upon request. -Safety Risk: The vehicle produces loud clunking or popping noises when driving between 10–20 mph or when turning and braking. It feels unstable and unsafe at times, especially on wet roads. This raises concern about potential front-end component failure while driving. -Reproduction and Confirmation: The issue has been reproduced and confirmed multiple times by Tesla Service in Vancouver, WA and Portland, OR. Tesla’s internal system shows that the issue was escalated for “in-car investigation by engineering,” but no permanent repair was completed. -Inspection History: Tesla technicians and engineers have inspected the vehicle several times. I also recorded multiple videos with cameras mounted inside the fender to document the sound and provide visual proof of the problem. -Warning Lamps or Messages: No warning lights appear. The issue is purely mechanical but noticeable during low-speed operation. The first symptoms appeared within the first month of delivery. -Manufacturer Contact: Tesla Service Centers in Vancouver and Portland are aware of the issue and have escalated it, but no resolution has been provided. This problem has continued for months despite repeated service visits. The vehicle was identified as needing further “factory-level investigation,” but I was told the local service centers cannot fix it. I believe the issue may be a manufacturing or design defect affecting suspension safety. My life is risk

I recently purchased a new Tesla Model Y (Juniper refresh). The vehicle has a loud clunking/creaking noise coming from the front suspension at low speeds, especially when driving over small bumps, turning into driveways, or when the road surface is uneven. The noise is noticeable inside the cabin and feels like a mechanical component is shifting. I brought the vehicle to Tesla Service. They confirmed the noise and told me it is not caused by the damper assembly but is a known issue that Tesla’s engineering team is currently investigating. However, no permanent fix is currently available, and the issue has not been resolved. I am concerned that this may be related to a suspension component failure or premature wear that could impact steering stability or control over time. Since this affects a brand-new vehicle and others have reported similar symptoms online, I believe this should be monitored as a potential safety defect. I am requesting that NHTSA track this issue to ensure Tesla provides a proper correction and repair campaign if necessary.

Issue: A consistent rattling noise, noticeable while driving at speeds of 10-40 mph over bumpy roads or pot holes.

I recently purchased a new Tesla Model Y in July 2025 . The vehicle has a loud clunking/creaking noise coming from the front suspension at low speeds, especially when driving over small bumps, turning into driveways, or when the road surface is uneven. The noise is noticeable inside the cabin and feels like a mechanical component is shifting. I brought the vehicle to Tesla Service twice the first time they could not replicate the sound, the second time they noticed it right away and replaced the front right and left dampers which did nothing at all, I think the noise is much worse after they did this. Then they said the noise is normal characteristic for this vehicle, I am sorry they should not be saying this in normal, especially for a brand new car. I am concerned that this may be related to a suspension component failure or premature wear that could impact steering stability or control over time. Since this affects a brand-new vehicle and others have reported similar symptoms online, I believe this should be monitored as a potential safety defect. I am requesting that NHTSA track this issue to ensure Tesla provides a recall and make the proper corrections and repair campaign as it is necessary.
