Codes P219C & P0301 have continuously came on, these lights MIL have made the vehicle go from AWD to 2 wheel drive while in motion. [XXX] vehicle was taken to Bay Ridge Lexus. In brooklyn NY. They over looked this issue and stated it was something else. This has been confirmed via multiple diagnostics machines. Lexus of Edison has also decided not to cover this repair under warranty. The danger of going from 4 wheel drive into 2 wheel drive while in motion is extremely dangerous. These warning lights/MIL once activated has also caused the vehicles sonar to fail cause a serious safety issue. My vehicle is available to be inspected as needed.

On a recent 2500 mile trip on 3 separate occasions while on interstate hiways and passing a vehicle the emergency braking system engaged automatically with warning lights and buzzers going off. This occurred with no other vehicles anywhere around for a quarter mile or more. On one occasion it occurred while driving in the right lane and with no vehicles in sight. Lexus special tech inspected the vehicle and had some calibrations performed but they will not tell me what they found in data captured by the vehicle computer or what actions they took and why they think the vehicle is safe to drive.

  • 2,800 miles
The contact owns a 2019 Lexus RX350. While driving with the adaptive cruise control activated and set at 72 mph, the driver reduced the speed to approximately 60 mph when switching lanes. After releasing the accelerator pedal, the vehicle continued to accelerate past the set cruise control speed of 72 mph and continued to accelerate to approximately 80 mph. After deactivating the cruise control feature, the vehicle continued to accelerate and the rpms increased before the speed eventually was reduced. The cause of the failure was not determined. Lexus escondido (1205 auto park way, escondido, ca) and the manufacturer were notified of the failure. Prior to the failure, the vehicle hesitated while accelerating and was serviced. The same Lexus dealer reprogrammed/flashed the transmission, but the failures continued. The failure mileage was 2,800.
