2008 Lexus RX400h Problems

Electrical & Lights -- Verified

The Check Engine Light may illuminate with code P0AA6 stored for a hybrid battery isolation fault. Our technicians tell us this may be caused by water intrusion into the high voltage battery case. The water may be a result of cracking body seam dealer above the rear door strut mount. Any water leaks should be repaired and the high voltage battery system inspected for water damage and repaired and dried as necessary.

RepairPal Expert Overview:

Two of the main control modules for the hybrid drive system are the Inverter Module and the Intelligent Power Module (IPM), which is located inside the Invertor Module. The IPM can operate at temperatures high enough to damage its electrical solder connections. Damaged solder joints can result in illumination of warning lights, various drivability concerns, and possible stalling of the hybrid drive system. Dealers will replace the IPM on affected vehicles to correct this concern.

2008 Lexus RX400h Reviews

Hade the same problem with the low tire pressure on. Could not get rid of it. It is still on

Love my car. Wish the mileage was better (about 26 mpg. Only problem is the "low tire" idot light is always on, even after filling tires with air. Might be the spare, which I can't get to without having it up on a lift.
