“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!”

“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,…”
