2015 LEXUS NX Complaints

While I was driving on the highway in cruise control, my car suddenly broke the cruise setting, slowed down, and the check engine light turned on. I pulled over and the car would not accelerate to over about 15-20 mph. I made it to an auto center, where they informed me that the reader said there was an issue with one of the fuel pumps. I am aware that there is a recall on fuel pumps in this model of vehicle and I believe that I experienced this defect.

The contact owns a 2015 Lexus NX 200t. The contact stated that while driving at various speeds, an abnormal, ticking sound was emitted from the fuel tank. As the failure persisted, the vehicle entered "Reduced Engine Power Mode" and the check engine warning light illuminated. The vehicle was taken to an independent mechanic shop where a diagnostic check was performed, and it was discovered that the fuel pump was defective and needed to be replaced. A local dealer was contacted and an appointment was scheduled to have the vehicle serviced. The contact arrived for the appointment but was informed that the fuel pump was on backorder and the appointment needed to be rescheduled. The contact informed the dealer that driving the vehicle felt unsafe because the commute exceeded one hour. The dealer assured the contact that the vehicle was safe; however, while driving the vehicle back to the residence, the same failure returned. After restarting the vehicle, the contact drove the vehicle to the residence. A second appointment was scheduled with the dealer, and a service advisor arrived at the residence of the contact in a rental vehicle and drove the vehicle back to the dealer for service. The vehicle was returned to the contact; however, the failure persisted. The dealer was notified and informed the contact that the failure resulted from a loose panel that technicians had difficulty bolting down. The vehicle was towed back to the dealer for diagnostic testing and repair. The contact test drove the vehicle with a mechanic inside the vehicle and informed the mechanic that the same failure remained noticeable. The failure returned a few days after the repair. The contact stated that both the dealer and the manufacturer avoided phone calls to service the vehicle. The vehicle was not yet repaired. The failure mileage was approximately 130,000.

The contact owns a 2015 Lexus NX 200t. The contact stated that while his wife was driving at an undisclosed speed, the brake pedal was spongy and made an abnormal clicking sound while depressed. Additionally, the vehicle shuddered while coming to a stop. The ABS warning light was illuminated. The vehicle was taken to the dealer, who determined that the ABS actuator needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

NHTSA has issued service bulletins regarding Lexus servo motor issues, primarily affecting the HVAC system, because these motors can have internal electrical malfunctions. This malfunction can cause symptoms like uneven or inconsistent air temperature from the vents, lack of airflow from selected vents, improper mode control, and the storage of Diagnostic Trouble Codes (DTCs) related to the damper control servos. This is an issue because it affects Safety and Convenience due to the following: While these issues primarily affect comfort and convenience by disrupting the climate control system, a malfunction of other servo motors (which control things like air flow direction or even steering in other situations) could create a safety risk. Experiencing this in my 2015 NX 200t today made me feel unsafe, as the vents were blowing out extremely hot air. And during hot Texas weather that is unsafe, and I have children that I have in the car with me at times. The Lexus dealership in Grapevine Texas is asking for $2,600+ to fix servo motor 1 and 2 after they ran diagnostics. It seems as if a vehicle that was in the same year and is experiencing the same exact issue as other vehicles in that year should also be covered as those that got it fixed under Lexus’ warranty. What makes the NX model different from the 6+ other models that Lexus a covered under the NHTSA safety bulletin/ recall?

Hello, I own a 2015 Lexus NX200T. On 9/13/2025 I was pulling into a spot to park, going slow at maybe 4-5 mph, my vehicle suddenly violently accelerates on its own. I had to slam multiple times on the brakes to avoid killing two pedestrians right in front of my vehicle. I was in seconds of killing them and pinning them between the vehicle that was in front of me. I did everything in my power to keep hitting the breaks as hard as I could until it stopped within inches of the two pedestrians. This was extremely dangerous and could have killed a mother and daughter in that split second. This appears to be a case of unintended acceleration, which I understand is a serious safety issue. I've been told by both the dealership and Lexus that because no damage occurred, it's not their problem. But this is clearly a safety defect, not just a maintenance issue. I would like Lexus to take this very seriously. I was shaken and very scared. I have NEVER had this happen before. Lexus suggested that the floor mats may have got caught - NO absolutely not. I have the mats locked in place with clips. I did not hit the accelerator instead of the breaks as that is what is assumed. No external damage occurred, but the unintended acceleration was violent. This incident took control away from me. Even though no accident occurred this time, the potential for injury or death is very high. I contacted Lexus and the dealership, but both declined to inspect the vehicle, stating it was not their issue because no damage occurred. I believe this a very serious safety defect that should be investigated. I am requesting NHTSA to investigate this potential defect in the Lexus NX200T model. If other owners experience the same, this could indicate a widespread safety problem. I was very lucky I did not kill anyone; it would have changed the day's events forever for the lives of two innocent people and myself. I don't feel safe to drive the vehicle after this incident in fear that it could happen again.

On June 3, 2024, a CARFAX Vehicle History Report for the 2015 Lexus NX 200T (VIN: [XXX] ) reflected an odometer reading of 37,783 miles as of August 14, 2021, and 26,148 miles as of May 9, 2023, when the vehicle was offered for sale . A subsequent CARFAX report dated August 19, 2025, altered the August 14, 2021 entry to show only 21,864 miles, while still listing 26,148 miles on May 9, 2023 . This change in recorded mileage demonstrates that the odometer history was manipulated to conceal a rollback and to make the May 2023 mileage appear consistent at the time of sale by Countyline Auto Center, Inc. The discrepancy of more than 15,000 miles in the same vehicle history constitutes odometer tampering and misrepresentation, which induced [XXX] to purchase the vehicle at an inflated value.

Brakes locked up while driving on the freeway, causing collision with another car and freeway guard rail. CHP report taken. AAA auto insurance does not seem interested in investigating manufacturing defect problems/issues. No dashboard warning/maintenance lights illuminated

The contact owns a 2015 Lexus NX. The contact stated that while driving approximately 65 MPH the vehicle suddenly experienced a loss of automotive power and stalled. The contact indicated that the failure had occurred while driving on a very busy freeway. During the failure, the warning messages "engine power lost" and "traction control off" were displayed along with the check engine light illuminating. The contact was able to restart the vehicle and drive to the local dealer who diagnosed that the low-pressure fuel pump was faulty and needed to be replaced. The vehicle was not yet repaired. The contact was informed that the low-pressure fuel pump was previously replaced under the NHTSA Campaign Number: 20V012000(FUEL SYSTEM, GASOLINE). The contact indicated that the vehicle had experienced that same failure listed in the recall. The failure mileage was 208,000.

The vehicle has 119285 miles on it. I have started to see oil leak from the transfer-case/transmission. I called lexus back in August 2023, they were aware of certain vehicle developing oil leak problems. They issued recall on certain vehicles and issued a TSB for oil leak repair. I called lexus today and took the vehicle to the dealership. There is an understanding that my vehicle won't be covered under recall even though the problem is known to lexus. This issue may lead to unexpected breakdown of the vehicle and lead to loose of control of the vehicle.

Left work for work in the morning and as I turned off my street to get onto a main street, I drive a block and the Check Engine Light appears and message appears on my console State "AWD System Malfuction." See Dealership Service. Drove to the dealership to drop off my care, and after 3 days of inspecting my car, the service specialist messaged me with a service summary of a list of items that need to be repaired to have my car run safely again. The total service totaling over 10k, which included repair head cylinder, valve guides, gasket, valve exhaust, cylinder head gasket cover. After speaking to the Service Specialist, he told me the issue is what they refer to "engine wrap" where the cover to the engine distorts (due to heat and time) and messes with the engine itself. He informed me this is a known issue that can occur with the 2015 NX200t.
