Tesla has issued two technical service bulletins to officially address front suspension noise on the refreshed Model Y. The bulletins, numbered SB-26-31-003 and SB-25-31-005 and dated 8 May 2026, were reported on 28 May by Not a Tesla App and Drive Tesla Canada. They formalise a fix for a rattling or knocking sound that some owners had reported when driving over bumps and rough roads.
The symptoms
The complaint centred on a persistent front-end noise on the refreshed Model Y, reported across the Premium RWD, Premium AWD, and Performance variants. According to the bulletins, the noise had been difficult for local service teams to pin down because its acoustic signature overlapped with several unrelated sources, making a clean diagnosis awkward.
Root cause and the fix
Tesla traces the condition to the front upper control arm (FUCA) mounts together with the internal valving and structural seating of the front damper assemblies. The repair procedure differs by trim:
| Trim | Required work |
|---|---|
| Standard | Already ships with an updated damper coil assembly — no damper replacement needed |
| Premium RWD / AWD | Replace FUCA mounts; replace left and right front dampers with updated parts |
| Performance | Replace FUCA mounts; replace left and right front dampers with updated parts |
Both bulletins also mandate a structural change that applies regardless of trim: technicians must remove the wiper-bracket pencil braces. Tesla found these braces were transferring suspension energy into the firewall and introducing unwanted harmonics, amplifying what would otherwise be a minor mechanical click into noticeable cabin noise. Where the full procedure is carried out, Tesla estimates roughly four hours of labour.
What it means for European owners
The refreshed Model Y — sold in Europe as the Juniper and built at Gigafactory Berlin — is the continent's best-selling vehicle, so a meaningful share of affected cars are in European driveways. Because this is a service bulletin rather than a recall, it is not a safety action: it is internal repair guidance for a noise, vibration, and harshness (NVH) complaint, and the work is typically performed under the vehicle's warranty for eligible cars. Owners noticing a front-end creak or knock over rough surfaces should raise it with Tesla service and reference the suspension bulletins rather than living with the noise.
Context
The bulletins land while the refreshed Model Y is driving Tesla's European sales recovery, and they reflect the kind of post-launch quality polish that tends to follow a high-volume refresh. Addressing the noise through updated hardware — rather than a software tweak or a one-off shim — suggests Tesla intends a durable fix for the platform going forward.
