I'd love to be able to recharge my batteries with a plug. Lexus should offer an upgrade to current vehicles that allow for this. And this feature should be made standard in future models.

I had an oil change by a non-Lexus person and the warning light went off requiring an oil change needed to be performed, even though I had updated the record manually. I tried everything imaginable to get this annoying light to go away. Nothing worked. I wiped out my maintenance records in the process, thereby making the whole feature worthless. It was also not allowed to enter dates in the past to fix records. Finally, contacting the dealer and trying about 10 times, I managed to get the light to go away by some weird combination of holding the odometer down while turning on the car. What the *)^*^? |

Our battery was disconnected as part of a repair when the car got slammed into by a driver running a red light. After repair, the shop couldn't get the electrical system right i.e. the windows and driver seat controls, etc. We took it to the local Lexus dealership. They had it for a FULL WEEK and after examining it for several days, they realized that the electrical system system needed to be restarted. Meanwhile, we and the insurance company are paying for a comparable rental. My point is: shouldn't it be somewhat obvious to a lexus dealership that the electrical system needs a restart? A light or something? I'd add that in, because from my standpoint, this seemed rather retarded and they are lucky they explained this to my wife, and not me. |

The Prius I4 was easily adapted to the Atkinson Cycle since just as one cylinder would be EXHAUSTING a portion of the mixture into the intake manifold the "opposite" cylinder would be beginning an intake strobe and thereby absorb the pressure pulse from the mixture being "exhausted", forced back into the intake manifold. Obviously the V6 has no such advantage, cylinder intake/exhaust(intake) synchronization, which may be why the Atkinson Cycle is not used on the RXh or HHL. Maxda solved this problem in the Millenia "S" V6 by switching to the Miller Cycle, using an SC to prevent reverse air flow in the throttle intake. Could a "reed" valve or "flapper" valve system such as used in 2-cycle engines be used in the throttle throat of a V6 to overcome this problem..?? Mill the heads to get a mechanical compression ratio of ~13:1 and then custom grind new intake camshafts to delay the intake valve closing to get an effective compression ratio of 10:1? |

I've come into the Lexus RX400h from an Infiniti FX35 so now, of course, I realize some of the things I was spoiled with in the FX: KEYLESS ENTRY and IGNITION--not having to dig for keys for 4 years was wonderful; BOSE SURROUND SOUND rocks and is clearly the best audio system out there; handles on the sides of the cargo area that drop the rear seats forward so that you don't have to crawl inside the car to load snowboards; lights in the cargo area that come on when the hatch is opened as with doors; guidelines on the back-up camera--with that wide angle lens I can't tell where I am. Of course the RX has its advantages over the Infiniti, most notably that it offers a HYBRID model. My husband mocks me because I could have gotten a Prius for roughly half the price (with keyless entry and ignition by the way) but I've been spoiled riding in the lap of luxury and I just can't go back!
