Preliminary Information
PIT5771A Wobble Vibration On Hard Acceleration
Models
| Brand: | Model: | Model Years: | VIN: | Engine: | Transmissions: | |
| from | to | |||||
| Chevrolet | Equinox | 2020 | All | All | LYX | All |
| GMC | Terrain | 2020 | All | All | LYX | All |
| Involved Region or Country: | North America |
| Additional RPO/s: | LYX, SAL or SPM |
| Condition: | Wobble / Vibration the customer will typically state this occurs on hard acceleration, 30 to 70 MPH. (WOT) |
| Cause: | Possible drive line vibration, information needed. |
IMPORTANT: This PI is to address the above scenario ONLY.
If able to duplicate the concern, record the event using the Pico Scope with the CH-51450TA246 Triple Axis Sensor. If the Pico reading at the above mentioned speeds is T1 lateral above 40 mg or above 30 mg with 10 mg of T3 lateral, return the vehicle to the customer advising them there will be a bulletin released and a field fix for this concern early in the first quarter of 2021. If this is NOT the disturbance noted in the file review perform normal NVH diagnostics.
