400h Hv battery
Gliderpilot replied to Siberpir8's topic in RX 300 / RX 350h / RX 400h / RX 200t / RX 450h+ / RX 500h Club
Apart from using Techstream for which I don't have a pc to run it on and object to paying mega bucks to have Lexus do it, is there an app that will check the battery state of the RX400h HV battery. I've got hybrid assistant, which I get very mixed results from and Torque Pro only seems to have a PID for the Prius. -
Hybrid RX should i?

If you find a good one it's worth the travelling to get it. I got mine from an independent dealer about 50 miles away. -

I'd pay a little bit more and go or a 450h, doesn't need a cambelt at 100k miles (cir £500) as it uses a chain and also the engine is more efficient giving better MPG. 2009 was the change over date. -
Two MOTs ago my 400h had an advisory that the rear bushes on the front arms were cracked and had excessive movement, which I witnessed for myself during the MOT. I bought a pair of arms and then proceeded to change them which was a right ball ache. It involved jacking the engine up as high as possible to remove the engine support to get at the mounting bolts or the arm. I then looked at the on line workshop manual and noted that the first step was "Remove the engine and transmission complete" glad I didn't get Lexus to quote for it.

Rx400h coolant

I'd keep a very careful eye on it as I've had my 400h for 5 years now and it hasn't lost a cm from either the rad or inverter. I don'y know your cars history but it could be weeping out from the water pump. -
The 400h gearbox is whats known as an e-CVT, there are plenty of videos on YouTube as to there construction. There are no metal belts or slipping clutches in there and in fact there is no reverse gear, reverse is obtained by reversing the traction motor direction and using the battery direct. The traction motor is constantly connected to the front wheels and power is mixed from the battery and ICE via an epicyclic gear unit. The rear wheels are driven by a second traction motor/differential unit. I tow a 1700Kg caravan and have done ever since I got the car 5 years ago and it still performs the same as it did then.

Short distances are a killer to the older 400h cars. The hybrid algorithm doesn't cut in until the engine is hot and that takes a mile or so. Not the case with our new Yaris where if you are driving around 30 mph with a light right foot you can use EV mode much sooner. Keeping the 400h in EV mode is very difficult, and can only be done when the engine is hot. That's what I've found after 5 years of ownership. As to the chap who only gets 19 mpg, I get that towing a 1700 kg caravan so there must be other underlying problems with the drive train or hybrid battery.

I've tried that with not a lot of success as I get figures from 1.5 Ah to 6 Ah, but no where near the 9.5 of a new battery. I'm getting an average of 28 to 29 mpg at the moment and the battery indicator is always somewhere around the 8 bar level and occasionally drops to 2 bars when at low speeds for a prolonged time.

Cruise control

Yup mine does the same, they need to upgrade the algorithm, but it's only by about 1 mph but it is noticeable.
