I purchased this vehicle on January 5, 2026, from a family-owned dealership in Broken Arrow, OK. The vehicle was purchased “as-is” with a guarantee of sale and a Carfax report. After purchasing the vehicle, I drove it home and it remained parked until January 8, 2026. On Thursday, January 8, 2026, the vehicle experienced an unexpected engine stall while I was driving. At the same time, the slip indicator light and traction control appeared to engage. I contacted the dealership immediately to report the issue, and the vehicle was towed back to JT Wholesale Auto Sales on Friday, January 9, 2026. On Tuesday, January 13, 2026, I was informed by the dealership that the vehicle had undergone a complete inspection and that no mechanical issues were found. Relying on this representation, I retrieved the vehicle and drove it home. However, after retrieving the vehicle, I continued to have concerns regarding its condition. On Thursday, January 15, 2026, I took the vehicle to Stellar Auto Service located at 2209 N. Yellowood Ave., Broken Arrow, OK 74012 for an independent inspection. Stellar Auto Service specializes in Lexus and Toyota vehicles. During their inspection, they identified the following issues: • Engine timing chain cover leak • Worn drive belt Stellar Auto Service was informed of the slip indicator light activation and the engine stalling that I had experienced. However, at the time of their inspection, they were unable to identify or reproduce any issues related to the slip indicator light or the stalling concern that I reported. On Sunday, February 15, 2026, the slip indicator light illuminated again, and the vehicle stalled while in operation. I was forced to safely pull off the roadway. I turned the car off, waited, restarted the vehicle, and drove home. The same issue occurred again on Sunday, March 8 and 15th, 2026. While driving, the slip indicator light illuminated and the vehicle stalled. I pulled off the road turned the vehicle off, restarted it.

THE PRE-COLLISION SYSTEM WAS UNEXPECTEDLY ACTIVATED FOR NO APPARENT REASON. TRAVELLING ON THE INTERSTATE IN LIGHT TRAFFIC ON A CLEAR, SUNNY AFTERNOON, THE CAR BRAKES SUDDENLY ACTIVATED, SEAT BELTS CLINCHED WITH NO WARNING SOUND. THIS HAS HAPPENED TWICE IN THE LAST YEAR (COINCIDENTALLY, IT OCCURRED AT THE SAME AREA ON THE INTERSTATE). THE CAR WAS TAKEN, BOTH TIMES, AFTER THE INCIDENT FOR INSPECTION AT THE DEALER. THE SERVICE DEPARTMENT WAS NOT ABLE TO REPLICATE THE ISSUE OR FIND ANY PROBLEMS. FOR ME, THIS IS A SERIOUS SAFETY CONCERN. SUDDEN UNEXPECTED SEVERE BRAKING COULD RESULT IN A MAJOR REAR-END COLLISION.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Lexus RX 350h verdict →
