Tl* the contact owns a 2006 lexus rx400 hybrid. When attempting to accelerate from a stop, driving on an incline, or making turns, the vehicle stalled intermittently. In addition, the check engine, hybrid check, and battery warning indicators illuminated. The contact coasted the vehicle to the side of the road and powered off the engine. Once restarted, the vehicle drove normally; however, the failures recurred. The vehicle was taken to treasure coast lexus (located at 5121 us-1, fort pierce, fl 34982, (772) 460-0000) where the technician cleaned the mass air flow sensor, cleared the failure codes, and test drove the vehicle in check mode.

2006 lexus rx400h totally shutting down while I was driving on i4 today. No power steering, no power brakes, engine died and luckily I was able to coast to a safe place from 70mph! Right before it happened, the check engine light came on, the engine misfired, then all of the lights on the dashboard came on including the check vcs, check hybrid and check anti-lock. Had to have it towed to our mechanic because it wouldn't start and could not be driven onto the tow truck. Codes that it threw said it was a high voltage system regenerative malfunction and a bad engine coil. It was a very dangerous situation with it shutting down on the interstate and I had no control what so ever! This was the second time this happened to me in this car and the computer was replaced the week after I purchased this car used in october 2017.

Vehicle appeared to enter "fail-safe" mode with reduced power while driving on highway resulting in reduced ability to control vehicle. Several minutes later, while driving on city street, the vehicle eventually lost all power while stopped at red light and could not be driven, and power-steering also failed. Warning lights included "check hybrid system," "check engine warning light," "slip indicator," and perhaps others. After turning off and turning back on at red light, there sufficient power to drive vehicle again, though "check hybrid system" and "check engine warning light" remained illuminated. A couple hours later, after restarting vehicle, warning lights were no longer on and vehicle could be driven normally. The condition appears similar to issue in toyota safety recall 13v‑396. However, our vehicle's VIN is not in the range of that recall. We have not yet contacted lexus dealership regarding this issue.

The check engine light and p0aa6 warning illuminated and vehicle went completely dead, could not start up. There were cracked body seams above the rear door strut mounts allowing water intrusion to flood the entire bottom well under the floor boards which shorted out the entire hybrid battery system. There were no visible signs of water intrusion inside the cabin of the vehicle, nothing was wet. Apparently, lexus has two tsb's on this issue, l-sb-0019-09 & l-sb-0045-09, on how to repair the seams since over time there appears to be a structural flaw allowing the seams to separate. The water intrusion happens silently and without warning and presents a severe safety hazard as you get water into an electrical system and parts begin shorting out without advanced warning. Imagine traveling at a high speed and the hybrid battery shorts and the vehicle abruptly stops! Or an electrical short starts a fire! Lexus is aware of the potential problem and how costly the damage is and the safety risks associated as a result and has chosen not to issue a recall or limited campaign to allow for a simple repair of the seams to prevent major damage from occurring.
