Relay Failure & Random Limp Mode
SeriousElectrics & ElectronicsA bank of six micro-relays located behind the front-right (passenger side) wheel well liner is a major failure point. Sticking relays for the starter or auxiliary water pump can cause "no-crank" scenarios, parasitic battery drain, or random "limp mode" where the car loses power.
Random limp mode, No-start/No-crank, High-pitched whine after shutdown, Sluggish acceleration in Dynamic mode
- Check if the relays (Mopar 6106093AA or updated 68530205AA) have been replaced
- Listen for noises from the passenger wheel well area after the car is off
