While driving roof glass just exploded. Sounded like gun being fired. No one was around us and glass blew outward. Almost had an accident from the explosion.
Ac doesn't work properly. We had several incidences when we were driving from houston (TX) to dallas (TX) in hot summer. The ac worked well when we left houston, however it stopped blowing cool air when we were in the middle of nowhere on highway. The air became warmer and warmer, and there isn't anyway that we can adjust the air volume nor to cool it down. We took our car to Lexus dealer for diagnosis and nothing unusual was detected. The dealer suspect the cool air clogged in condenser that blocked cool air from entering the cabin. This is truly a safety concerns to all Lexus owners. When we drive on highway, in the middle of nowhere in hot summer, the car cannot provide a comfortable environment to driver and passengers, especially for babies or older passengers. It's a safety design flaw with Lexus Rx350.
Ac drain was clogged/malfunctioned which resulted in constant condensation in footwell. The problem persisted which resulted in black mold in the carpet and footwell insulation beneath the carpet. Lexus service advisers insisted the ac drainage line was clogged by a spiderweb but the picture they took didn’t show any spiderweb. After researching many Lexus forums, it seems like a common problem and many other people were given the same excuse of a spiderweb clogging the drainage line that also resulted in mold. Lexus doesn’t seem to want to take responsibility for the problem and rather blame a spider. They estimated $10,000 to replace the carpet and fix the problem. Other people on forums were also quoted $8,000-$15,000 as well.
The navigation system randomly marks places of interest while there is no input from the driver. This in effect cancels the navigation information causing distraction when relying on that system. It also “marked” an address twenty miles from the destination and gave directions to that sight. Dealer cannot find cause and it has not been repaired.
