Verbatim excerpts from NHTSA complaints, by component
Engine and engine cooling
2 reports
“The contact owns a 2019 Lexus NX-300H. The contact stated that while driving uphill at an undisclosed speed, the vehicle stalled. The failure was a recurring failure. The dealer was contacted, and the vehicle was diagnosed. The contact was informed that there was coolant leaking into the engine block and that the engine needed to be replaced. The contact associated the failure with NHTSA Campaign Number: 20V064000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was 103,755.”
Fuel/propulsion system
2 reports
“While the car was idled at a stop light, the warning "reduce engine powere appeared". I took the car to the vehicle and learned this was linked to code P125d71 for fuel pump valve control- a known recall”
Back over prevention
2 reports
“In heavy rain situations I get an error message stating all front active safety systems (forward collision warning, etc.) do not work. The error states to clean or clear the front sensors of the vehicle. There is nothing blocking the sensors but in heavy weather these situations become much more important. Lexus states this is normal when heavy water situations come into play. I understand for going through flood waters but I don't believe it should be in heavy rain. I feel this is a major safety hazard that should come with warnings.”
