Question type: Maintenance & Repair

12 Answers


If I'm not mistaking, dealer warranty is 10 years or 100k miles. Is yours a 2006 or 2007? Reading some posts, people have had them for 125k miles to 150k but that's about it.

We have a 2006,150K miles. So far no problem with Hybrid battery. I found so many complaint for RX300 and 350 engines and now cracks on the dashboard for which the dealer has been dilly dallying that I decided not to ever buy a Lexus.because Lexus' quality and customer service are much worse than other auto companies. I have high end cars and top sports cars all these years (Gullible?). Now I am convinced that there are better cars(may not be flashy) for much less money, e.g Hyundai. SURPRISE!

We have a Lexus RX 400h , late 2006, it has now done 395,000 K's , we have just changed the rear discs and the front discs were changed at 200,000 K's, ( that is about 250,000 miles for the rears and about 125,000 miles for the front discs ) I do NOT know what the service is where you are , But the quality of service here in the ACT ( Canberra ) Australia is Fantastic . So ,--- Arunr76,-- I would say check another dealer and report the dealer with whom you are dealing with to Lexus HQ in Japan

Thank you jacko101. Actually the dealer changed the dash board sooner than I expected. It makes me unhappy and insecure to read all the complains about Lexus because i thought it is the most long lasting SUV. I have 153k miles and it has been running like a champ. I had brakes overhauled and a new battery put on a year or two ago. Besides changing tires I have had no problem. But reading all these complaints, I am becoming uneasy especially of the hybrid battery. Nobody has any answer how long the hybrid can last. Yours has 395k km is equal to almost 250k mi which is reassuring. Actually my dealer in Toledo, OH, usa is good. I had timing belt changed at 105k miles. It is supposed to be changed every 90k mi. Other than that except oil change, no big service has been required. It is my wife's car. I offered her a Mercedes SUV. But she loves this Lexus and would not part with it.I assume that your hybrid had no problem. Thank you again.

My 2007 400H with 187,000 miles on it (mostly in Arizona) still has original brakes and I've seen no degradation in mileage or hybrid battery condition. I was worried, because our hot weather is a battery killer. We go through 12-volt batteries once every 18 to 24 months, and so far the dealer has replaced it for free every time! The only major replacement I've had to make was the radiator, which developed a pinhole leak. I love this SUV and would but one again Lexus except for that navigation system scam that Lexus has going. I refuse to pay $200 to update maps that I get for free on my Google Maps app.

my wife's 06 Rx400H has 154k miles with a leak on left top of radiator. It has been 4/5 years and I had not put any anti fridge . It has ran through 20 to 95 degrees in Toledo. When I got the timing belt changed 4/5 years ago at 105K miles, I found that the timing belt was like new unless the dealer gave me the new one and left the older intact. I would suggest that you do the same thing with the radiator. Other than that the car is a champ.

I like to thank jaco101 for your input about the Hybrid.


My 2007 Rx 400h was replaced free of charge after 10 years, Lexus acknowledged the flaw. Fantastic service!
