Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I made a 6-mile trip from my garage and back (12 miles total). The next day, my neighbor asked me to come outside to inspect my driveway where I found a trailing stream of oil. The oil leak was substantial enough to visibly observe an unbroken ribbon of oil spanning the entire length of the asphalt street leading to my driveway and a large pool of oil where I waited momentarily for the garage door to open. Needless to say, I then discovered a large pool of oil under the front of the engine on the passenger side. It was the lower oil cooling line. No warning signal appeared reflecting the leak or low oil pressure. I remembered receiving a letter from LEXUS Corporate stating that this was a known defective part and could be repaired at the dealer at no cost to me. However, the caveat was that the age of the car could not exceed 10 years and the mileage 150,000. My mileage was only 106,400, but the car age exceeded the 10 year limit. Did LEXUS think that the defective part would magically heal itself after 10 years? Why put a limit? LEXUS would NOT assist me in any way, so I had the repair completed at an independent shop. I only repaired one side and now fear the other side will go out and the leak will not be discovered in time before blowing up the engine. I'm white-knuckle driving in a car I used to love. I'm extremely disappointed in the lack of "good-will" provided by LEXUS for a known defective part (a rubber hose, replaced with a metal one) because they would not stand behind their product. Loyalty is a delicate trait, and they have lost mine.

My 2011 Lexus RX350 was running fine as I ran errands for groceries and other items around town one day. Then, out of the blue, I realized that after returning home and parking in my garage, there was a trail of oil in my driveway, leading to my vehicle. I looked under the engine area and noticed a pool of oil. I had a certified mobile mechanic come to my home and provide a diagnosis. This diagnosis was that a hole had formed in the rubber Engine Oil Cooler Line, and drained nearly all the oil in my engine. He mentioned that one more mile and I could have had total engine failure. He proceeded to replace it with a new Genuine Lexus, all metal Oil Cooler Line. I contacted Lexus about this incident, but they provided no compensation for this occurrence, even though there was a short 4-year technical service bulletin they issued barely a year after production, that called out this was indeed a flaw in their design. After doing some research, I see this is a VERY common issue, with many in the past most recent years having this very issue. Yet, Lexus has not recalled this, nor reimbursed those that have suffered from this manufacture defect. I am really hoping that something can be done by NHTSA and/or Lexus to resolve this issue that I am certain is still plaguing thousands of Lexus owners on the road, and putting our and those around us' safety at risk. Surely, a part that obviously and very consistently degrades over the course of 5+ years so often, needs to be addressed and recalled for the sake of safety and integrity.

On Saturday July 15, 2023, at between about 8:00 and 8:30 a.m. CDST the vehicle was parked overnight in a garage, spontaneously caught fire and burned and was a total loss. There was a smell I would associate with an electrical fire. People reported hearing a car alarm and a "popping sound" before the fire. The fire department extinguished the fire and had the car towed out of the garage of a condominium association. Fire damage to property (except the subject car) was minimal but there was extensive smoke. In my opinion based on this incident, electric/hybrid cars should not be parked indoors.

I was driving my 2011 Lexus RX 350 on July 7, 2023, to a swimming pool. I was pulling into a parking spot just rolling to a stop with my foot on the brake. The car suddenly accelerated with grate speed and ran on the curb of the sidewalk forward to a small rock wall, I immediately turned the vehicle to the right and pressed down on the brakes, but the vehicle kept moving about 45 feet and came to a stop after crushing another two vehicles in the parking lot. These two vehicles were destroyed and not repairable according to the insurance company. For my car the right front side was crushed and both airbags on the drive side deployed, and my chest and legs were injured by the airbags. The biggest injury was my mental injury which made me unable to return to normal life.

AS WE WERE DRIVING, MY CAR SUDDENLY STARTED RUNNING ROUGH, ENGINE STARTED SPUTTERING, CAR THEN SLOWED DOWN, SEVERAL WARNING LIGHTS APPEARED ON THE DASHBOARD, AND THEN CAR ABRUPTLY STALLED IN THE MIDDLE OF THE ROAD AND COULD NOT BE RESTARTED. WE HAD TO PUSH THE CAR TO THE SIDE OF THE ROAD IN A SAFE PLACE UNTIL A TOW TRUCK ARRIVED TO TOW IT AWAY. I RESEARCHED AND LEARNED THRU SEVERAL MEDIA RELEASES THAT A SAFETY RECALL WAS RECENTLY ISSUED AND CURRENTLY IN AFFECT TO COVER THIS SAME EXACT ISSUE IN SEVERAL TOYOTA AND LEXUS MODELS. 1.8 MILLION CARS ARE AFFECTED UNDER THIS SAFETY RECALL. MY CAR EXPERIENCED THE IDENTICAL ISSUE AND UPON MECHANIC'S INSPECTION WAS CONFIRMED TO HAVE A FAILED/FAULTY FUEL PUMP THAT NEEDS TO BE COMPLETELY REPLACED. CAR IS UNUSABLE, REPAIR IS COSTLY AND SHOULD BE COVERED DUE TO NATURE OF DEFECT, UNDER THE RECALL. WE'VE COME TO TRUST THE TOYOTA AND LEXUS BRAND AS WE'VE ONLY OWNED TOYOTA AND LEXUS VEHICLES OVER SEVERAL YEARS. THIS SAFETY ISSUE IS DANGEROUS/UNACCEPTABLE AND HOPE WE'LL RECEIVE THE CUSTOMER SERVICE WE'VE COME TO EXPECT AND APPRECIATE AS LOYAL CUSTOMERS. THANK YOU. *TR
