“The contact called on behalf of her son who owns a 2010 Lexus RX350. The contact stated that she had taken her son's vehicle to the car wash. The contact stated while at a complete stop, in the carwash drive-through, the vehicle accelerated independently and the driver's side of the vehicle crashed into the wall on the left side of the carwash bay. Heavy metal structures fell on the vehicle. As a result, the windshield was shattered and the ceiling of the vehicle was bent. The air bags failed to deploy. There was no warning light illuminated. The contact sustained two large contusions below the knee of her left leg. The injured area later became swollen and bruised. The contact sought medical assistance. A police report was filed. The vehicle was towed to a tow yard. The vehicle was then towed to the contact's residence. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 12V305000 (Vehicle Speed Control). The manufacturer was notified of the failure and informed the contact that they would send a field inspector to retrieve the Event Date Recorder (EDR) in order to determine the cause of the failure.

“We had a known oil line ruptured the oil cooler, there was a serviceable and sit out to the dealers to only repair if it was leaking and they extended it to 10 years $150,000 miles our vehicle had a rupture at 170,000 miles we were never told about the recall or we would have it done earlier we now have sparkles in our oil this is the part that it doesn't leak it ruptures I'm sure all out could place a fire and it certainly is can cause catastrophic damage to the engine 1500 to repair”

“Odometer Fraud. The contact purchased a 2010 Lexus RX 350. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 139,000. It was discovered that the mileage was 177,000 in 2022. The contact contacted the Police, and the contact was advised to file a civil suit.”
Steering
14 reports
“When parked and turning the steering wheel or driving at low speed you hear a clunk / clunck noise vehicle makes knocking noises as it jumps up and down (bumpy) or vibrates when driving You can also feel it in your hands. Also it rattles and makes noises when turning. It feels like there is no lubrication. The drive feels not only unstable but also is very distractive while driving. Took car to Lexus and was told it is steering column or shaft or both; quote around $4000 with labor. Seems like a lot of people had same problems and the steering is manufacturing defect that should be recalled as a safety concern.”

“Abs actuator failure causing wheels to lock up in wet conditions along with loss of control..I nearly crashed into pedestrians when it failed. suddenly check abs light came on along with abs system malfunction...I could've been killed or killed someone. lexus will not cover the repair though they did for customers under 50k miles and under warranty which is completely criminal. Any lexus of Toyota highlander with abs assembly part # 44510-48080 needs to be recalled and replaced at Toyota and lexus immediately. They want $4000 to fix the system knowing they sold a critical safety part that malfunctions.”

“TRAFFIC ON I 5 N CAME TO A SUDDEN STOP. I STEPPED HARD ON THE BRAKES. THE ABS FUNCTION DID NOT WORK AND MY CAR SKIDDED AND WOULD HAVE GONE INTO THE LANE ON MY RIGHT IF I HAD NOT CORRECTED THE SKID. THIS COULD HAVE RESULTED IN A SERIOUS ACCIDENT WITH POTENTIAL BODILY INJURIES. I HAD THE VEHICLE INSPECTED BY LEXUS DEALER AND THEY SAID NOTHING WAS WRONG WITH THE ABS BRAKE SYSTEM AND THAT THIS COULD BE ONE IN A THOUSAND INCIDENT. I HAVE DRIVEN SEVERAL OTHER MANUFACTURERS AUTOS WITH ABS AND KNOW THAT THE LEXUS EXPERIENCE IS NOT HOW NORMAL ABS BRAKES SHOULD FUNCTION. THIS IS A SERIOUS DRIVING HAZARD AND I HAVE NOT RECEIVED A SATISFACTORY SOLUTION TO THIS ISSUE FROM LEXUS TO DATE. UPDATED 04/08/14”
