2019 LEXUS NX Complaints

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.

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

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.

Car was running normally and going at 50mph then all of a sudden car abruptly lost power and went to 10mph and dashboard lit up. Very scary as we also had our kids in the car--I can only imagine how dangerous this would have been if we had been on the highway going 70mph. Dealer diagnosed with low pressure fuel pump being bad. Lexus paid for the repair due to some lawsuit settlement but these cars should be recalled due to sudden loss in power!!

During heavy wind driven rain the front sensors start to show errors on the screen. These errors cause the the advance safety systems and parking sensors to deactivate. The warnings state to clean the sensors. Sometimes stopping the vehicle and turning off and on the ignition seems to resent but it does happen again. Usually this takes about 30 minutes of heavy rain to cause the. All other functions of the vehicle work but most safety systems appear to deactivate because of the sensors. This should not happen during a time when the systems are most needed.

Trunk is defective. Trunk will not open unless it is manually opened, which is hard because it is powered. If there is an accident and a person needs to escape, they would be stuck inside due to these defective trunks. Many others are experiencing this issue online.

The contact owns a 2019 Lexus NX 300. The contact stated that while stopped at a red light, the RPM started to fluctuate. There was no warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed, and the mechanic retrieved DTC: P0300 and P11EF. Additionally, the check engine warning light was illuminated. The vehicle was then taken to a local dealer to be diagnosed, and the contact was informed that the fuel injector was faulty and needed to be replaced. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 25V028000 (FUEL SYSTEM, GASOLINE) as a possible cause for the failure. The manufacturer was notified of the failure. The approximate failure mileage was 144,000.

The contact was informed that the front axle needed to be replaced. The front axle was replaced; however, the sound persisted. The vehicle engine was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 35,000.

Air fuel imbalance. Air fuel ratio Imbalance. Rough idling. System too rich bank 1. Requires cylinder head removal. Other VIN#'s recalled; however, my vin # was not accounted for though experiencing the exact issues and codes.

I have attempted informing Lexus of this situation. To my knowledge, they have not pursued the case. On October 31, 2023, we brought our NX300 [XXX] ) in at 44,806 miles. The left parking brake actuator was inoperative (also rendering the cruise control inoperative). To get to the dealership from Ormond Beach, I removed the appropriate fuses to avoid any undesired operation from the unit. I was hoping any problems would be covered by warranty—it had under 50,000 miles. The Basic Warranty had expired. The Powertrain Warranty was still in effect. Strangely, brakes are not listed in either warranty. This was definitely NOT a wear and tear item. After inspection by Lexus mechanic, the failed actuator would not and could not be covered by warranty. The ‘out-the-door’ cost was $1371.43 (RO# [XXX]). I asked for the old part, which I still have. There is an extreme manufacturing defect I found. Lexus charged $997.63 for the part. The same EXACT part is available online for $37.70---OEM is $189.00. I understand price markup is required for any business, but over 500% may be a bit excessive. I was truly shocked by what I had found within the sealed actuator. The why and how the actuator actually failed is blatantly obvious and could be a serious safety hazard for anyone driving a car with this type actuator that was manufactured in and around the same time as this one. The motor within the unit is held in place by 3 torx head screws which (all three) were completely unscrewed and were rattling above their appropriate threaded hole. Each screw has little or no threadlocker (Loctite) on the threads. The compression ring on top of each threaded hole is not compressed. This indicates the screws were never torqued to the proper specifications during manufacture. I believe there is a possibility of a brake malfunction due to manufacturer's defect in the brake actuator part.
