I have had the alternator go out.
and countless sensors
it goes in the shop about 1 time a year for at least 500 in repairs. I will never buy a lexus again biggest piece of crap. I will buy a ford for my next car. I broke down 100 miles from home and had to hitch hike. scary. I [non-permissible content removed] hate this car
2000 AWD, purchased used in 2011 w 110K. The good-smooth drivetrain, ride, reasonably comfortable seats. Only replaced 1 O2 sensor in first 40K miles. The bad-$$$ to fix: $1200 for timing belt/H2O pump. At 152K, knock sensor and sub harness, air fuel ratio sensor, valve cover gaskets: $2100. At 156K, front 2 catalysts: $900. The ugly: TERRIBLE MPG: Avg 16-17 around town, rarely more than 20 all highway. The big culprit seems to be the gearing - very short geared - about 2900 RPM at 70MPH. Extra weight for AWD does not help, nor do the side mirrors, the size of small flat screen TVs. No compass. Radio and HVAC controls look the same. Too expensive to own-would not buy another.
The engine and trans work flawlessly together, although the 3.0 can feel underpowered.
The suspension is soft but not too soft, so the ride is very pleasant.
Kill all the wind noise around the A pillars.
Re-imagine the audio and HVAC controls - both sets of buttons and knobs are the same, and not logical.
The little info screen in unreadable in bright sunlight.
Make it more stable in crosswinds - it gets blown around easily.
And give it a compass! Even Chrysler minivans have a compass.
But most of all - improve the fuel economy - we rented a 2013 Chevy Silverado, 5.3V8 that attained better overall fuel economy than the 3.0V6 in the RX300!
i had transmission probrum 53,000 miles replaced new one after 50,000miles later transmission fell again in right middle of in death valley ca. it was so bad we had to wait 3 hours to toeing truck to arrive.i called lexus on thursday 4-16-20013 they told me get back to me on tuesday on 4-23-20013 still no answer. they told me to wait one more day. i am so angry about whole thing taking such long time to get back to me. i have rental car, have to return.
After reading reviews I thought I would add to the pot. My Lexus RX 300 SUV transmission recently went out and is in the shop as I type. Waiting for the transmission place to give me an estimate. He has had it and had to break it down. It needs to be replaced he said but is still calculating the parts and labor. I hate to hear what that is...I thought these were long lasting cars if you kept up the maintenance, which is why I bought it. It has 170K miles, so I guess it did last a bit longer than some of the others I read on the blog. I hope it runs like it use to or better after they replace this transmission.
Build better transmissions and other parts that you have gotten many complaints about.
