2026 Tesla Model Y suspension problems

Filed Oct 18, 2026 · Suspension, Wheels · CA

The car sways/oscillates side to side on highway speed. Took the car in for service on XXX. Multiple works performed on the car such as wheel alignment, Camera Pitch corrections, and tire balance. The service report indicated "The vehicle was released for the customer to monitor." After the car returned to me, I drove on the highway, on the way home, and found the oscillation amplitude has gotten worse. I reported the concern immediately to the [XXX] Tesla Service center. I was told they will call back. Subsequently I left two more urgent messages but never received a call back. This problem, per Tesla's message, asking the customer not to drive on highway due to safety concerns. Unfortunately, I am unable to avoid driving highway for practical daily purposes. On XXX, my daughter vomited (motion sickness) due to car oscillation side to side driving on highway XXX. The oscillation is especially bad when driving on [XXX]. This problem has made me and my family felt very unsafe to drive the car on highway which has prevented us from taking longer trips. This problem has prevented my for normal day to day driving needs and also affecting my family health. Tesla Technician personally ride with me and confirm the defect on XXX.

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.

Tesla was in FSD and had the latest software update installed on 8/6/28 which included the new FSD version released. On 8/7/28 on the way to work that my wife takes every time she goes to work the FSD ran over a large pot hole which it had never done before on the previous FSD version. The car started having rattling of the steering wheel and a rattling noise from over the rear driver wheel area. The next available Tesla service appointment was on 8/27 but we walked in and Tesla offered to do an alignment and found that the driver front and rear rims were bent from the pothole and we had to be pay close to 1800$. Thereafter, the rattling over the rear wheel well is louder but Tesla has not accommodated us with an earlier service appointment and refused to make any accommodations for the FSD update resulting in this damage.

Steering wheel vibration occurs at highway speeds between 70 and 75 mph on a 2026 Model Y with under 1,000 miles at time of complaint. The vibration was reported to the dealer, who performed a tire balance and alignment check and confirmed both were within specification. The vehicle was tested by the dealer during a service ride-along and no vibration was detected by the technician. However, vibration was independently confirmed by the owner in a same-model loaner vehicle on the same road, suggesting the issue may not be isolated to a single vehicle or tire set. Similar vibration issues have been reported by other owners of the same model year in online owner forums, with no documented fix currently available. Safety concern: reduced steering feedback at highway speeds. The vehicle remains available for inspection upon request.

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

Tesla 2026 Model Y was involved in a severe motor vehicle accident directly caused by a critical software and/or hardware malfunction of Tesla’s Full Self-Driving (FSD) system. At the time of the incident, the vehicle’s Full Self-Driving (Supervised) software suite was actively engaged and driving the vehicle. While navigating, the system suffered an abrupt and uncommented control malfunction. Despite prompt attention, the autonomous system executed an erratic, uncorrectable maneuver that overrode human intervention thresholds, completely failed to respond safely to the immediate driving environment, and directly caused a collision.

The car is unstable on the highway when there is a crosswind - either from wind gusts or from large vehicles. The car is easily pushed by wind until lane assist activates to stop it from going outside of the lane. It feels very unsafe to drive on the highway. This is how the car was when it was bought. An alignment was done during the first Tesla service visit and that helped slightly. The second Tesla service visit they said the vehicle was operating as expected and then checked wheel balance after I insisted. They said they fixed wheel balance but it still did not change how the car handles in crosswind. The third Tesla service visit (different service center) they said the vehicle was working as expected and said they could not drive for a significant distance to test. If lane assist ever fails when I'm not ready to instantly react to a gust of wind, it feels like it would easily move into another lane or off the road. When passing large vehicles where wind changes direction, the car sometimes gets pushed left and right which sometimes triggers an alarm and shows an on screen message saying to take control of steering. I test drove another of the same model car for an hour and had the same unstable feeling in the wind but was unable to test long enough to find an area with high crosswind.

2025/2026 Tesla Model Y Juniper experiences noticeable vibration starting at approximately 75 mph on smooth highways. The vibration is felt throughout the entire vehicle: steering wheel, doors, seats, and pedals/floor. It is not limited to the steering wheel. Tire balancing, alignment, and foam checks have all been performed with no resolution. Tesla service states the issue is ‘normal/within spec.’ Video of the vibration with speedometer visible is attached. This matches a widespread pattern reported by other Juniper owners.
