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 ...

P0AA6 Check Engine Light warning and code and Water Leakage by Trunk Door Stays and Damage to Hybrid Battery System
The problem was that when coming to a stop, I would get the sensation of letting a manual transmission car stop without engaging the clutch; i.e. a shuttering sensation. The diagnosis was that the shift solenoid "E" encased in the transmission was faulty (PO770). The problem is that this part has been replaced twice within a 12 month period leading me to believe there is something really wrong with the diagnosis, treatment and possibly the t...
A vibration may be noted in the brake pedal or steering wheel when the brakes are applied. This is commonly caused by warped front brake rotors. The affected rotors must be re-machined or replaced to correct this concern.
Power steering "growling", leaks around P/S pump and white smoke when car is first started in morning.
If your power steering pump is making noises or leaking, get it fixed ASAP or you will likely be replacing your alternator too. The alternator is located right below the P/S pump and if fluid drips into it it will short out the alternator, this has been occured many times.
Also, if you get a puff of white smoke in the morning it may be a bad speed sensitive steering solenoid, which screws into the power steering pump and has a vacuum line ...
Clunking noise coming from rear when stopping and starting. The bushings in my rear carrier arms (I think, it's been awhile since I replaced, crawl under car and find the arm that moves around significantly when pressure is applied) were COMPLETELY worn out, the rubber was missing and the metal housings were just flopping around.
Use aftermarket bushing ADUS 505 (about $35 each, search online) to rebuilt each arm. Repair isn't too bad if...
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.
Higher mileage cars can develop creaking and groaning noises in the front suspension, particularly when coming to a quick stop. Inspection and replacement of any worn parts should correct this concern.
The Check Engine Light may illuminate with codes P0171 and/or P0174 due to a lean running engine. Symptoms may include: Hesitation on acceleration, lack of power, and poor fuel mileage. This is commonly caused by a dirty mass airflow sensor. Our technicians tell us the sensor may be cleaned using an approved cleaner but replacement is often required to correct this issue.
Just spoke with my Lexus dealership.
Svc. Tech knew exactly what I was talking about and said he'd had "numerous" complaints. Basically, the problem is the SENSOR from the foot pedal to the engine. Very common in 04-06 RX and EX models!
He reported that THE SOFTWARE UPDATE does not stop the problem... And said there IS NO FIX, and that if I wanted to " fix it"... I'd want to consider going to a '07 model or newer. Said Lexus never s...
