1. At [XXX] on [XXX], I was pulling into my gym's parking lot, when I stepped on the break to park my car, instead of stopping, the car accelerates rapidly and crashed through the other side of the sidewalk where there were light pole and cement walls, throwing me forward and backward with seat belt on, I was in total shock! 2. My insurance sent a field inspector to the body shop 2X in hope to repair my car but ended up declaring it a Total Loss. 3. Lexus said they would send a field tech to get the EDR (Event Data Recorder) data from my 2018 Lexus RX350 within 30 days, but the results won't be available for 30-45 days after that. Lexus's slow response to this accident concerns and disappoints me b/c it was a serious crash that Lexus should treat it seriously and promptly. 4. The disbelief of a 'young' car with only 12297 miles could have issues like this puzzled me and drove me to do a lot of online research, then I came across this site [XXX] which contains an article titled '10 Common Problems of A Lexus RX350'. Problem #5 described exactly what had happened to me: 'ONE RECURRING PROBLEM THIS CAR HAS IS THAT THE SYSTEM MALFUNCTIONS SEVERELY. THIS TYPICALLY HAPPENES WHEN THE DRIVER IS TRYING TO PARK THE VEHICLE. REPORTS PAINT THE SAME PICTURES REPEATEDLY: THE DRIVER IS PULLING INTO A PARKING LOT, THEY PUSH THE BREAK PEDAL, AND INSTEAD OF STOPPING, THE CAR ACELERATES RAPIDLY, WHICH RESULTS IN A CRASH." Based on this article, it seems that Lexus should have issued a recall, but no! 5. The strange thing was that NO airbags were exploded/activated, yet the vehicle was damaged to beyond repair, it makes me wonder if there was an issue with the airbags too. If this incident had occurred at an intersection, I dare not imagine the outcome...I could have been killed or critically injured along with other innocent people on the road. I am very traumatized by the whole experience and sadly, the feeling seems to have gotten worse as time goes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

I am writing to raise a serious concern regarding a issue with my 2018 Lexus RX450hL involving the brake actuator. Since purchasing the vehicle at 63,000 miles, I have noticed hissing, clicking, and squeaking noises when applying the brakes. As the mileage increased to 83,000, these noises have worsened, becoming unbearable. In addition, I am experiencing a shaky driver-side mirror and a rusting hood latch, both of which present safety concerns. For a vehicle under 5 years old , I believe these problems do not reflect the quality I expected, particularly given the premium price I paid. According to Lexus' Technical Service Bulletin (TSB) #L-SB-0032-23 Rev, issued in October 2023, which addresses squawk or knock noises from the engine compartment when the brake pedal is pressed or released, affecting models like the RX450hL. My vehicle exhibits symptoms similar to those described in the TSB. The vehicle was regularly maintained by the previous owner at Lexus of Thousand Oaks and Woodland Hills. Despite this, the major part like brake actuator has failed prematurely. Given Lexus' reputation as a luxury brand, it is unacceptable that such a critical component would fail before the vehicle is 5 years old or has reached 100,000 miles. The combination of the brake actuator defect, the shaky mirror, and the rusting hood latch is disappointing, especially for a vehicle of this caliber. When I initially contacted Lexus Customer Service, I was also dealing with rusting parts and a failing brake booster. Lexus of Cerritos provided a repair estimate of around $5,000 for brake actuator. I was advised to reach out to Lexus Customer Service after my request for a good faith repair was denied due to the inability to obtain the complete maintenance history. However, I have since confirmed with the previous owner and Lexus that the vehicle was regularly serviced. I am also aware that Lexus has issued brake actuator-related recalls for several models.
HVAC servo motor failure. There are many complaints on internet if you google. Multiple other lexus models have CSPs regarding same problem too..

The driver-side mirror shakes noticeably while driving making it hard to see what's on your left, specially at night. Even though I'm reporting in 2024 w/ 55k miles, I just bought this L-Certified CPO Lexus 1 week ago, so the problem was likely there before. There are a couple of other signs that this car doesn't handle the South Florida heat very well and my guess is the adhesive on the mirror has started to fail. There is a service notice on late model NX to address this that replaces the entire mirror assembly and they'll likely do this as well when I take it in, but it is a fairly simple issue to resolve yourself following some YouTube videos even if they're not specific to this make/model.
If you by mistake forget to put your car on Parking the transmission does not lock by itself creating a hazard of movement of the vehicule that can cause an injury's or even worse. That was reported to the dealer and dismissed the issue as normal.
Two days ago, upon entering our vehicle, there was a smell of gasoline as we drove. Our fuel guage wend from 1/4 tank to EMPTY in minutes. I pulled into a gas station and when attached the nozzle, gas entering the tank was POURING out from underneath. I drove the car to the venue we were headed to and parked on a dirt/gravel …

Two days ago, upon entering our vehicle, there was a smell of gasoline as we drove. Our fuel guage wend from 1/4 tank to EMPTY in minutes. I pulled into a gas station and when attached the nozzle, gas entering the tank was POURING out from underneath. I drove the car to the venue we were headed to and parked on a dirt/gravel spot so as to limit fuel runoff to nearby vehicles. We had the vehicle towed to Bob Tyler Toyota, the nearest Lexus type service center. I called service at Lexus of Mobile and the employer stated that there are no recalls. The free flowing fuel endangered not only my and my wife but anyone around the vehicle. No warning lights whatsoever. The tow driver concurred that fuel was POURING until the tank was emptied. I have not been contacted by the service department thus far.

The driver side indoor door handle no longer works. Despite my model being part of the special service campaign 20LC02, dealer says that my VIN number is not covered despite it being the exact problem described.
The car makes a "Brake Squawk" noise when the brake pedal is applied. The noise sometimes is unbearable. Dealer replaced the brake actuator. The noise came back after a few months.
