Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When driving uphill on a local city street, where there was a metal plate in the road, my Lexus RX350, would detect the metal plate, and apply the pre-collision system. When I reported this issue to the dealership, they offered to shut off the pre-collision system as a work around. I was told that the system was working properly and that there was a warning about the potential for this to happen in the manual. I reported this issue to Lexus corporate as well. I could reproduce this issue and offered both the dealership and corporate to view the video. Both declined my offer. …”

NHTSA complaint #11045762, filed 2017-11, 32,934 miles

“Was driving at approx. 70 MPH on highway 71 when I heard a loud crash. There were no other vehicles in sight around my vehicle so I thought a tire had blown out. After inspecting the vehicle and getting back inside, I realized the sunroof glass had exploded. I didn't realize it immediately as the cover was closed at the time, thankfully. As I had purchased the vehicle 5 days before, I called the dealer, who responded that I must have been hit by a rock. As there were no vehicles around for miles, I am confident it was not a rock but a manufacturer defect. …”

NHTSA complaint #10747198, filed 2015-08, 300 miles

“Dynamic speed control randomly (twice) has lost settings & control. Setting it at 60, car increased speed to 85, and ignored car in front of me, almost causing a crash. Lexus has not followed up with me on this. Voice recognition often functions incorrectly resulting in distracted driving, and has almost resulted in me driving out of my lane or off the road several times. Example: ask it for directions to palo alto medical foundation: result; gives me a list of south american restaurants. Contacted Lexus about this. Only response - take it to a dealer. I have an appt with one july 11. …”
