NHTSA complaint #11015089, filed 2017-08, 110 miles“My IS 250 had a recall/TSB for a severe engine problem that involved rebuilding the entire engine. They performed this in 2013. Barely 1 year later I experienced the same problem, I brought it back to the dealer and was told they could not replicate the issue. 2 weeks ago the problem happened again so I brought it back to the dealer, now they inform me the car needs a new engine and is going to cost over 4000 dollars for a fix they did not perform correctly the first time.”
NHTSA complaint #10692109, filed 2015-03, 105,000 miles“I noticed a black spot in my rear view mirror one day and did not think anything of it, however the one spot turned into multiple streaks. It's getting harder to see out of the mirror which to me is a safety issue. I noticed that there are many complaints on this issue and there should be a recall on this defect as well. I have to make an appointment for the recalls on the melting dashboard and doors and engine. Lexus should really take care of this problem. I have purchased several new vehicles however I have had more problems with this car than I did with my other cars.”
