Engine

“First, We are a victim of fraud and scam and are distressed since day one and loss of thousands of dollars. After searching and reviews, we bought a 2015 Lexus RX350 for family use from a seller who had owned this vehicle for over five years but the seller never disclosed and represented in the sale of this vehicle that It was rebuilt and had engine front cover timing gasket leak! They said it was clean title and didn’t have any issues. Plus the blind spot sensors had issues. The same day these problems were recovered after we bought it and from the same first day we tried to return the vehicle and used all other option legally from day one till now to resolve it with the seller, but they didn’t want to resolve neither return it or fix the problems with vehicle but they kept denying. Vehicle been sitting in parking lot since the first day of bought and never able to register and it’s been over 8 months. Also found out, these year models like mine 2015 RX350 timing cover leak were common problem back then. I’m desperately asking to issue a fix remedy by Lexus or Toyota therefore, please help with this.. thanks in advance!”

Power train

5 reports1 crash
“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,…”

Steering

“The contact owns a 2015 Lexus RX. The contact stated that while operating the vehicle, the steering wheel was shaking and vibrating, and it was loose. The vehicle was taken to a local independent dealer who replaced the control arms, but the failure persisted. The vehicle was taken to an independent mechanic, who diagnosed the vehicle and determined that the power steering rack needed to be replaced. The vehicle was not yet repaired. No further information was available. The failure mileage was 118,000. The VIN was not available.”

Structure

5 reports
“One early morning in November, I opened the rear door on my RX to remove my rollator walker. I am handicapped. I opened the door using the switch under the door handle. The door opened normally, and I reached in to remove the rollator and the door jerked down about a foot then continued to close with several jerking drops. It scared me, but I was able to jump out of the way of the door as it dropped. The temperature that morning was in the lower 40’s which was perhaps the lowest early morning temperature we had seen this fall. I feel that the low temperature may have contributed to the problem. I opened the door again with the switch. The door opened fully but closed again in a similar manner as described above. I was able to hold the door up with one hand and removed my rollator with the other, which was rather difficult due to my limited strength. Later in the day, after the temperature rose, the door opened and stayed open as it should. I discussed the problem with my local Lexus dealer, and they felt that the problem was most likely due to worn shocks which are used to hold the door open. I am familiar with this problem. I owned a 2002 Lexus RX and had a…”
