Our car never had any issues, and unexpectedly on Sunday October 10th while my husband was driving it - he heard a loud explosion underneath the car. Immediately there was smoke and then in matter a minutes the car was in flames. My husband had enough time to remove our daughter and the car seat but the car was completely destroyed. We want to know what happened- our car was in incredible condition, low mileage and always kept up on all the maintenance

The contact owns a 2015 Lexus RX350. The contact stated that while driving over bumps on the roadway, there was an abnormal rattling sound coming from the vehicle. There was no warning light illuminated. In addition, the contact would lose slight control of the vehicle while turning the steering wheel to the left as the power steering became loose without warning. The vehicle was taken to a dealer where it was acknowledged that the power steering had failed, and the contact was provided an estimate for the repair. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 45,000.

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!

225/60R18 100H Mileage on car when tires purchased 33,410(11/4/2021 mileage when tire failed 40,702.(6/8/2023) These tires have a 50K warranty. At 40,846 (6/26/2023) two more tires failed. I was told tread separation was issue. This dealer put my family at Risk! When the car went in for shaking they said the tire was defective. They replaced it and charged me $214, the tire only cost $150 new. I asked if the other tires were OK, the girl I paid said "the bad tire was from a different batch than the three remaining tires and they were OK." 2 weeks later 2 more tires go bad, putting us back in the car with defective tires put my family at risk. This dealer is dishonest and Dangerous. They charged me for 4 new tires total cost $492.35 when the set only cost $600 new and we only received 15% of the use of the tire, before they went bad. 1 tire going bad is unfortunate, 3 tires same problem is a Defect and they should have been replaced NO Charge. Anyway you need to get these tires off the road before someone has a serious accident or possibly already has.

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 similar rear door shock problem after about 175,000 miles on the car. The rear door on that car was manually operated. If the door didn’t stay up on a manually operated door it was more of a poor-quality issue than a safety issue since it was readily apparent if the door was not going to stay open. The situation with an electrically operated door is quite different. The person opening the door completely relies on the door to stay up when it is opened. In addition, the door could be operated by a child who may not be able to react to the falling door. I had the shocks on the door replaced by the dealer at a cost to me of slightly more than $400. I discussed the safety issue with the dealer and followed up with a reply on a satisfaction survey they had sent. In the repair writeup the dealer
