The contact owned a 2017 Lexus RX 350. The contact stated while making a left turn exiting a car wash, the vehicle unintendedly accelerated independently and crashed into the commercial building where it came to a stop. The brake pedal was depressed but the vehicle was in full throttle and failed to stop. The air bags did not deploy. No warnings light illuminated. No Medical Attention was needed. During the failure, the contact was the only occupant seated in the vehicle. The contact sustained injuries to the head, black and blue marks on the left side of her leg and shoulder as well as her left knee sustained swelling the right of her bottom was also bruised. A police report was filed. The vehicle was towed to impound lot by the insurance company and then towed to a salvage lot. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 53,000.

1. Engine timing cover leaking 2. Oil could leak out emptying which could cause the engine to stop working at any given time 3. Problem has been confirmed by Hennessy Lexus dealership in Duluth, GA but they will not fix it. 4. Vehicle has been inspected by the dealership 5. No signs, I found out from the dealership after taking it in for an oil change

Sunroof exploded while driving down the road!! Called lexus they said it must be due to a rock breaking it.

My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus RX350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.

I bought this car in March 2020. We took it to the Kingsport, TN Lexus dealer Sept. 14, 2020 for several warranty issues and a recall factory interior front door handle replacement. Today, 9/3/24 the front driver’s side interior door handle broke and the door cannot be opened from inside the car. Called local dealer who said that it was guaranteed for 12 months or 12,000 miles. I find this completely unacceptable. I am [XXX] and have driven cars for over 40 years and I have never had a car handle break. For this handle to basically last four years is unacceptable and unsafe for any Lexus driver. At this point I question as to whether the repair was actually made. If in fact replaced, I am shocked by the lack of quality in a repair that was to have fixed a serious issue. Driving a car when you cannot open the door is not something I recommend to anyone! I have called Lexus National customer service and they have opened a case. I do plan to have this repaired and I do not plan to pay for what I consider to be very low quality part replacement.

When checking the emergency SOS function in my car I found that it did not work. I called Lexus support and was told that the following safety systems would no longer be operative: Lexus Enform Safety Connect including Automatic Collision Notification; Enhanced Roadside Assistance; Emergency Assistance Button and Stolen Vehicle Locator; Lexus Enform Remote including Remote Engine Start/Stop, Door Lock/Unlock, Vehicle Finder, Guest Driver Monitor, Vehicle Status and Alerts, Key Fob Remote Start, and Integration with Alexa and The Google Assistant; Lexus Enform Destination Assist including 24-hour live response center agent; Lexus Enform Service Connect including Vehicle Health Report, Vehicle Alerts, and Maintenance Alerts; These include safety systems that I rely on, especially when driving on interstate highways, and were included when I purchased my car. I had no warning that the services would cease to function in October of this year. Lexus states that these systems will no longer function because telecommunications providers will no longer support 3G service. This is certainly a safety issue for me and for other drivers and I believe that Lexus should be required to modify the hardware/software in these vehicles to function in a 4G/5G environment. Lexus representatives state that Lexus has no plans to correct these safety issues. I am requesting that NHTSA review this matter as a highway safety issue.

235/65r18 tire. I was driving on the highway and all of a sudden it was a loud noise and immediate tire noise. I struggled to slow the vehicle down and pull to the side of the road The tire is absolutely destroyed both on the inside and the outside side walls of the tire. I could have had a horrible accident because the car was completely out of control when the tire blew

On [XXX], my wife, [XXX] , was driving our Lexus RX 350 when she noticed engine smoke without any prior notifications from the vehicle. Concerned for her safety, she pulled over and contacted Geico for assistance. Geico arranged for the vehicle to be towed to Motor City Lexus, a trusted Lexus dealership in Bakersfield. Once we the dealership performed a diagnosis they advised that the issue involved coolant being leaked into the engine that caused the smoke with in result caused the engine blow head gasket. After doing some research I saw an article from consumer reports about some Lexus and Toyota SUVs doing the exact same thing which made me decide to wrote about this incident. I am including the link regarding the report [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof glass spontaneously exploded into thousands of pieces while driving on the interstate. There was no impact what so ever to the glass and the outside temperature was 95 degrees. The shattered glass fell into the vehicle and left a huge hole in the center of the glass panel. My safety was at risk due to explosion of glass while driving at an elevated rate of speed of 75mph. All while traveling over 100 miles from home and then having to drive the vehicle home with a gapping hole in the roof. The surrounding drivers were also at risk due to the glass flying off and hitting their vehicles. There were no cracks or failures to the glass prior to the glass exploding. There were no warning lights, messages or symptoms.

During a routine maintenance at the Lexus dealer where vehicle was purchased, we were told that there was a potential oil leak from ("potentially") the engine where the block, cylinder head, and timing cover components meet. The quote we got for the repair is $18,781.52 as a good portion of the car needs to be disassembled to access the motor. This issue was only brought up after the warranty expired. The Toyota 2GR-FKS 3.5L V-6 engine in this vehicle is known to leak in this area due to the gasket mating surfaces in the area mentioned above not sealing completely requiring silicone RTV caulk to be installed during engine assembly. If this is not done correctly leaks occur. Lexus refuses to make good on this saying the car is out of warranty. Ironically, after receiving the quote from the dealer for the repair, we received an offer to extend the warranty - available only after this $18k repair was completed.
