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.

While vehicle was being driven into the garage the vehicle suddenly accelerated on it own without driver pushing on gas pedal. Vehicles automatic emergency braking did not engage. Vehicle then struck steel shelving and wooden cupboards causing considerable damage to vehicle. The body shop where the vehicle was taken for repair experienced the same surging phenomena when they moved the vehicle. There were no system warning lamps visible prior to the episode.

Vehicle has been reported before for similar problems. This time, no power, severe stumbling, lurching. Check engine light comes on along with warning indicators that the electrical systems have failed. Lexus notified again and vehicle will be towed to dealership. This car is dangerous and life threatening as we were in traffic with no power. Dealer did not notify us of any problems prior to sale but this car qualifies as a lemon under AZ law. Additionally, if other Lexus owners are having this problem, they should immediately stop using the vehicle and park it before someone gets injured/killed.

Vehicle stumbles and loses power when accelerating. Loss of power when passing. Both situations caused driver to abort action for fear of not having the power to enter the roadway or pass vehicles. Lexus dealership acknowledged the problem with this vehicle and said the fuel pump was replaced because of a recall. Problem continues to exist and is dangerous to driver and others. Dealer further recommended we -?? change our driving habits -?? to remediate the problem. Not acceptable.

Car was pdi and delivered on 06/14/20 with an open recall 20la01 that was likely to be a life-threatening issue. Even after pdi was performed, the breaks were disfunctional, so had to take the vehicle for service on 06/19/20. Lexus found that rotors required resurfacing to fix the breaks and at the same time completed the open recall 20la01. However on 07/03/20, the car stalled in the middle of a highway traffic putting the pax thru a life-threatening situation. Car has been finally towed to the service and I am verbally promised that the car has been fixed to not present any life threatening issues. Since it is just 15 days of purchase and vehicle been into the service review for 3 times with some life-threatening open issues, I am requesting Lexus to either refund or provide me a replacement.

  • 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.
