2007 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.

Exhaust & Emissions -- Verified

Hybrid vehicles may notice a rocking or surging feeling at freeway speeds of 70mph. Our technicians tell us new software is available for the hybrid powertrain control module to correct this concern.

Miscellaneous -- HarleyCoco

Our Lexus displayed a check engine warning and P0AA6 Code and then immediately stopped working. Upon inspection at dealer, the entire bottom floor of the cabin (under the floor boards) was flooded without any visible water damage inside the cabin or any visible point of water entry. We were given an estimate of approximately $11,000 to repair because the entire hybrid battery system had to be replace, inverter and other components along with ...

Drive Train, June 29, 2011

RepairPal Expert Overview:

A module inside the hybrid drive inverter module may contain inadequately soldered transistors. These solder joints could fail under high electrical loads, resulting in illumination of various dashboard warning lights, drivability concerns, and/or engine stalling. If the vehicle were to stop unexpectedly, this would increase the risk of a crash. Owners will be notified in July 2011 if their vehicle is involved in this recall. They will received a second notice when parts become available. Dealers will inspect the hybrid inverter module production number to determine if the inverter contains the suspect transistors. They will replace any affected modules.

Drive Train, September 4, 2013

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.

2007 Lexus RX400h Reviews

Have 190,000 miles, only changed the tires and the radiator.Best car ever. Considering changing the time belt now!

Brought my 2007 Lexus RX400h to the dealer, Prestige Lexus, for 75K maintenance and was told the oil pan had to be replaced because the drain plug was stripped. $540 for the repair. I told them that they were the only people who had ever touched the car, which their records verify. If the plug was stripped it was because their mechanics had done it and now they wanted me to pay for their mistake. Was told, we'll talk to the service manager. Still waiting to hear if they will do the right thing or convince me never to buy another Lexus.
