Example complaints

“We have owned 3 Lexus and all 3 of them have had problems with the digital radio print out. We took it to a dealer and they would replace it for over $500.00. We also contacted the customer service dept. And they would do nothing to replace it. It seem to me that such an expensive vehicle should have a radio that works.”
NHTSA complaint #10181244, filed 2007-01“Our 1999ls400 Lexus is experiencing malfunctions with the electronics in the dash. The odometer and the speedometer are working intermittently. Lexus wants 1200.00 to pull out dash and send away to repair. I am concerned this is a huge safety issue. I don't know whose replacing what and are they certified Lexus mechanics??? Are these early model LS400's having electronics problems or is this just a single case? Please let me know.”
