Lexus RX 400h - Answered Questions & Fixed Issues

Does it still have a warranty on it? If so I would use that while you got it, and get it fixed free of charge. There is probably a cosmetic plastic cover hiding the alternator. However if you locate the belts than it will lead directly to the alternator.

there is a 3rd fuse box under above the passenger feet.You have to remove the plastic panel which is just held in with a few clipsGive it a tug, it'll come off.Fuses are hard to get at and drop behind the carpet so put a rag or something to catch them.What fuse is gone?It'll be the very last one I bet its a b"£$"$"d of a job.here is the fuse diagram if it helpsthe description is cryptichttps://cimg4.ibsrv.net/gimg/www.clublexus.com-vbulletin/1120x2000/2016_nx200t_interior_fuse_mapping_a3da8559dbe96e11fce02fd7536430e5e3f8d542.jpg

Hello Steve Smith, Assuming your LUG NUTS are torqued properly... The issue COULD have been caused when your tires & wheels were remounted... BUT you should have has Traction (or STABILITY) and ABI LIGHTS almost immediately... (means tire shop) Else... One or more of your Wheel sensors has been moved enough to provide MARGINAL operation. In any case the PURCHASE PRICE of these sensors is NOT cheap... I'd suggest you SCAMPER quickly back to your TIRESHOP... and come to an UNDERSTANDING (who done it = who pays). Get your codes (DTC) read to see if your car knows WHAT is up. In my opinion Carnac the Magnificent

I would say if you just bought it from a garage take it back and ask them to sort it.

Peace of mind. I have had a used car examined by the Royal Auto Club before purchasing it, only to discover later that the engine had been rebuilt, that third party electronics for the doors were beyond fixing after three trips to a electronics specialty shop, and a persistent squeal was not going to be eliminated in the engine. This was before the car died. One would think that getting it okayed by a mechanic before hand would be some protection and you would be informed of any prior work on the vehicle. You can buy extended warranties from other than the dealer for less money. https://www.slideshare.net/amtwarranty/the-importance-of-extended-car-warranty-when-pruchasing-pre-owned-vehicle

These cars a very sensitive about the battery voltage.

Next step is to check your fuses and relays for the lights. The location of these is covered in your owner's manual.

Check with your manual to see if there is a radio reset code that needs to be entered to restore operation. Also check with the dealer to cover all bases.

Yes it is very important to have your mechanic check the car before you purchase, he should pay special attention to mileage and service history also road test and number of previous owners.

Please refer to the owners manual.

Either a failing transmission or something in the hybrid system, not right Doubt the dealer has anyone trained to work on a hybid

Transmission going faulty and coolant leaking from its gaskets.This problem indicates towards faulty/ cracked inverter coolant reservoir .But i suggest first get the transmission inspected by the proper transmission shop.Transmission getting faulty, with vehicle driving fine , is bit rare.---------- The coolant leaking from inverter reservoir, is very much noticed in Lexus RX vehicles.------ ----------- The inverter is not repairable and is replaced as an entire unit.It is also costly part, approx $7000 including labor.But suddenly this problem showing up is rare.-------- You need to get it reinspected at any other proper shop, and get exact confirmation.---------- The inverter is the black rectangular thing with the rectangular warning sticker on it. The black plastic stealth bomber shaped thing on top of that is NOT part of the inverter. If you remove the engine cover on the driver's side of the engine, the inverter is the whole unit under that (with the plastic coolant reservoir on top) and it sits on top of the ******.----------- Getting both transmission and inverter reservoir inspected is advisable.------------ Thanks.Helpmech.

If the engine is running more often I would be checking the condition of the batteries. The whole idea is to run on the batteries until the voltage becomes too low in which case the engine starts. Take it back to the dealer service department for a diagnosis of the problem.

And what sort of answer are you looking forWe can't tell you anything from the internet on smells

Best advice is to find a new car dealer that has 2nd hand cars in the same lot as new cars. They have a reputation to look after so you will get a better deal than if you select some 2nd hand car dealer that doesn't care if they see you again on not.

Can you ensure the car is in park?Move lever to D and then back into Park and see what happens.I have heard with this particular model, we have the environmentally unfriendly RX 330, that the batteries lack of charge may play havock with the electrics in these cars.I religously charge my battery every six months with a smart charger so its always in peak, I also find a quick zap at the first cold snap of autumn / winter gives us trouble free motoring.

Lower part of engine facing the front of car. You have to get at it from under the front of car.-----------------obd2expres.co.uk

if this car has the daytime running lamp option they are supposed to be on.

chec fuses--also body control module or instrument cluster issues--switch may be worn from bad fan motor

Hi, you have done something that is not recommended. Avoid disconnecting the battery because it erases the system info that operates like our brain of the car. There may be shortcuts but I recon you going to a dealer and reloading the system info. If your battery is low it is a very good move to replace with a new one before it is too late. It is a common problem with Lexus RX H.
