Jul 23, 2025 Crash

3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.

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.

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)

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.

I just picked My Car up from Bakersfield Motor Ciry Lexus . My engine was replaced with a engine at this location with 65k . I have now notice my car jerk during acceleration from a stop position or uphill possibly from the transmission . I respectfully requesting a claim be opened on this issue as I didn't have the issue until engine replacement. I am also requesting a courtesy evaluation and stress test on the transmission at my home dealership Newport Beach Lexus. Ever since engine replacement the car has been bucking during acceleration 0 to 45.

The Dealer Northtown Lexus in Amherst, New York replaced the vacuum pump per a factory recall. As a result, the vacuum pump continues to function improperly. The dealership, whom repaired the vehicle without my authorization, refuses to complete the vehicle repair.

Sep 26, 2022

On 5/8/2020, Northtown Lexus replaced or repaired the vacuum pump. Northtown Lexus required the vehicle to be returned for repair twice, following the initial repair on 5/8/2020. After three attempts, the vehicle's vacuum pump (per a factory recall) is not functioning properly. Northtown Lexus refuses to further diagnosis this defective vacuum pump and continued to decline any and all requests for repair. The vehicle operates abnormally ever since this factory recall was originally addressed by Northtown Lexus on 5/8/2020.
