## Recalls for the same vehicles and component

- [21V424000](/recalls/nhtsa/21V424000.md), 2021-06-03: ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## Other bulletins for the same vehicles and component

- [N861 Range Rover 18SEP26](/bulletins/11038355.md), 2026-10-07, Other: POWER TRAIN. Malfunction Indicator Lamp \(MIL\), loss of start/stop functionality and no communication during diagnostic sessions.
- [N900 Range Rover 21AUG26](/bulletins/11037146.md), 2026-09-08, Other: POWER TRAIN. Malfunction Indicator Lamp \(MIL\) illuminated on the instrument cluster. The root cause of the symptoms is the catalytic converter over temperature.
- [N900 Range Rover 16JUN26](/bulletins/11034940.md), 2026-07-08, Other: POWER TRAIN. Customers may experience loss of power, rattling from underside of the vehicle and the Malfunction Indicator Lamp \(MIL\) illuminated on the instrument cluster.
- [SSM76460 \- 01JUN26](/bulletins/11034858.md), 2026-07-08, Other: POWER TRAIN; ENGINE. Malfunction Indicator Lamp \(MIL\) is illuminated on the instrument panel.
- [N900 Range Rover 20MAR26](/bulletins/11031117.md), 2026-04-07, Other: POWER TRAIN. Loss of power, rattling from underside of the vehicle and the Malfunction Indicator Lamp \(MIL\) illuminated on the instrument cluster. The root cause of the symptoms is the catalytic converter over temperature. The calibration of the exhaust sound tuning feature allows for too many repeated activations in a short period of time, resulting in catalytic converter over temperature and leading to Diagnostic Trouble Codes \(DTC\) P0420 and P0430 being stored in the Powertrain Control Module \(PCM\).
- [TUCC\_MAR2026\_33](/bulletins/11030969.md), 2026-04-07, Other: POWER TRAIN. There is a MIL light on
- [Range Rover\_N900 02\-20\-20](/bulletins/11029864.md), 2026-03-06, Other: POWER TRAIN. Loss of power, rattling from underside of the vehicle and the Malfunction Indicator Lamp \(MIL\) illuminated on the instrument cluster.
- [Range Rover\_N884\_17OCT25](/bulletins/11024664.md), 2025-10-31, Other: POWER TRAIN. Misfire MIL Incorrect Operation
- [Range Rover\_N884\_18AUG25](/bulletins/11022606.md), 2025-09-04, Other: POWER TRAIN. The Malfunction Indicator Lamp \(MIL\) does not operate as expected. After a misfire has been identified and then the misfire is no longer present, the MIL should turn off after the start of the 4th drive cycle. Currently the MIL turns off after the 2nd drive cycle.
- [TUCC\_AUG2025\_33](/bulletins/11022471.md), 2025-09-03, Other: POWER TRAIN. Audible clunk noise from rear driveline during low\-speed throttle inputs.
