2021 Hyundai Palisade Electrical Problems

Your engine is making rattling sounds and losing power while driving, sometimes shutting off completely without any dashboard warning lights to alert you beforehand. The first incident occurred after an oil change when the oil level dropped below a quart, but subsequent incidents happened even with a full oil level, suggesting a different underlying problem. The dealership hasn't been able to identify or fix the issue because it occurs intermittently and can't be reproduced during service visits.

Your vehicle started on its own while parked in your garage with the engine off and keys nearby but not in use. The engine was idling at an extremely high RPM while all dashboard displays were completely dark. You retrieved the keys and started the car normally, which brought the RPM down to standard idle. This poses a serious carbon monoxide hazard in an enclosed garage. The fix will likely require diagnostic testing of the engine control module and electrical system to determine why the vehicle self-started.

While driving at 40 MPH on three separate occasions, your power steering stopped working and multiple warning lights appeared on your dashboard. Your headlights and turn signals also stopped functioning, and when you shifted into reverse, your backup camera didn't work. This suggests a serious electrical system failure that affected multiple vehicle systems simultaneously. A full electrical system diagnostic and possible replacement of the battery, alternator, or main electrical control modules may be needed to restore all functions.
