Fitment on this one is narrow by design: the 2015 Lexus NX 300h and its 2.5L four-cylinder hybrid (2AR-FXE), in front- or all-wheel drive. Every clearance, torque value and test procedure in this service and repair manual is the one Lexus published for that combination, not a figure carried over from a neighboring model year or a different NX drivetrain.

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 break
I purchased this vehicle in 2015 - it has been dealer serviced and has never been in an accident. At just under 90,000 miles on the odometer, a major fluid leak started. It turns out that the rear main (crankshaft) seal had failed, causing a leak of transmission oil. No warning lamps or messages appeared. This failure resulted in an extraordinarily expensive repair, over $2,500.00 at the dealer, Lexus of Greenwood Village (Colorado). It was not covered on warranty. This is a major safety is
WAS ENTERING HIGHWAY AND REACHED SPEEDS OF ABOUT 70MPH WHEN ALL OF A SUDDEN THE SUNROOF EXPLODED AND SHATTERED. I IMMEDIATELY CONTACTED LEXUS AS I KNEW NOTHING COULD POSSIBLY HIT MY CAR AT THOSE SPEEDS AND NOT COME FLYING THROUGH THE ROOF AND DAMAGE THE FRAME AND OTHER MOVING PARTS. THE ONLY THING THAT SAVED ME WAS THAT I HAD THE INTERIOR SLIDE HATCH HALFWAY CLOSED SO GLASS DIDN'T ENTER THE VEHICLE. I IMMEDIATELY SHUT IT AND DROVE TO THE DEALERSHIP. THE AGENT WHO LOOKED AT MY CAR REPORTED THAT T
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: Wh
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
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 include
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 roll
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.
ON 7/29/2018 - WHILE DRIVING THE VEHICLE IN ROUTINE STREET (NON-HIGHWAY) TRAFFIC I FELT A SLIGHT DRAG AND THEN THE YELLOW WARNING LIGHT APPEARED INDICATING 'AWD SYSTEM MALFUNCTION 2WD ENGAGED.' LESS THAN A WEEK EARLIER I HAD THIS PROBLEM ADDRESSED AT A LOCAL AUTO SHOP AND THEIR DIAGNOSTIC INDICATED THIS WAS A TURBO GATE PROBLEM AND THE GATE WAS NOT CLOSING ELECTRONICALLY. I WAS ADVISED TO TAKE THE VEHICLE TO THE DEALER IF THE PROBLEM RETURNS. I HAVE CHECKED ONLINE AND SEE THIS APPEARS TO BE A
