Service bulletin SB-25-31-004
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball joints, bushings or damaged suspension links. If the feature determines that an inspection at a Tesla Service Center is required, a customer-facing alert will appear on the touchscreen.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
| SB-26-31-003 | 2026-06-02. Service bulletin. Certain Model Y vehicles may emit rattling or knocking noises when driving over bumps or rough road. The condition can be improved by replacing the front upper control arm mounts, replacing the front damper assemblies, and removing the wiper bracket pencil braces. This document is for vehicles that have already had the front upper control mounts replaced and the wiper bracket pencil braces removed. Replace the front damper assemblies with updated parts. |
|---|---|
| SB-25-31-005 | 2026-06-02. Service bulletin. Some Model Y vehicles may emit rattling or knocking noises when driving over bumps or rough road. The condition can be improved by replacing the front upper control arm mounts, replacing the front damper assemblies (Model Y Premium and Performance only), and removing the wiper bracket pencil braces. Inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the front upper control arm mounts with updated parts, replace the front damper assemblies with updated parts (Model Y Premium and Performance only), and remove the wiper bracket pencil braces. |
| SB2016003R1 | 2024-02-20. Service bulletin. Certain Model 3 high voltage batteries may not have a sufficient quantity of bolts for the contactor DC link busbars, which may prevent the vehicle from charging or powering properly. |
| SB1831005R1 | 2022-05-02. Service bulletin. On certain Model 3 vehicles, the front stabilizer bar link ball joint studs might crack at the flange. As a result, the nut that attaches the stabilizer bar might lose torque. This might result in noise coming from the front of vehicle while driving on rough surfaces. |
| SB-20-31-006 R3 | 2021-11-08. Service bulletin. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints. |
| SB-20-31-006 R2 | 2021-11-08. Service bulletin. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints. |
| SB-20-31-012 | 2020-12-14. Service bulletin. On certain Model Y vehicles, the Front Upper Control Arm (FUCA) to steering knuckle fastener for both LH and RH sides of the front suspension might be loose, or the FUCA to steering knuckle nut(s) might be missing altogether. |
| SB-20-31-004 | 2020-09-08. Service bulletin. Certain Model 3 vehicles were manufactured with LH front damper assemblies that do not meet internal specifications, which may result in elevated NVH (Noise, Vibration, and Harshness) from the front of the vehicle. |
| SB-20-31-005 | 2020-09-08. Service bulletin. Certain Model 3 vehicles were manufactured with RH front damper assemblies that do not meet internal specifications, which may result in elevated NVH (Noise, Vibration, and Harshness) from the front of the vehicle. |
| SB-20-31-002 | 2020-04-06. Service bulletin. On some Model 3 vehicles, the LH and/or RH rear damper top mount bolts were not fastened according to internal specifications and may create noise, vibration, and harshness. |
