NHTSA complaint #11723732

Owner complaint summary

After the automatic start/stop system engages, the engine stalls and completely shuts off shortly after the vehicle begins moving again. This occurs after the vehicle restarts and travels only a few feet. When the stall happens, the vehicle loses power and the engine stops functioning while the car is in traffic. This has occurred two separate times: once on a busy highway and once while entering a roundabout. Both incidents created a dangerous situation where the vehicle could not maintain power in active traffic and could have resulted in a crash. A yellow emissions warning light also appeared on the dashboard. The dealer indicated that an intermittent oil pressure sensor code was present but no parts were replaced and no corrective action was taken. The dealer reset the system and stated they could not reproduce the problem. The vehicle is now being returned to me without repair despite the safety risk. An engine stall immediately after the start/stop system restarts the vehicle creates a serious hazard because the vehicle can lose power in the middle of traffic. I believe this issue may be related to the automatic start/stop system or an oil pressure sensor fault affecting engine operation.
