2023 Lexus IS 300 Electrical system Brakes Engine & cooling

I am reporting a severe, unresolved safety hazard involving my 2023 Lexus IS350]. The vehicle is continuously flashing 'Braking System Malfunction,' 'Crash Light,' and 'Engine Light' alerts on the dashboard. This is the second major acceleration and braking system failure since purchasing the vehicle brand new.The authorized dealership, Meade Lexus, has repeatedly failed to properly diagnose or repair this critical braking issue over a 7-month period. On multiple service visits, the dealership documented that they...

simply 'lubed' the rubber around the gas cap, reset the dashboard warning lights, and returned the vehicle to me without performing actual mechanical repairs to the braking system. The service manager explicitly instructed me that I must drive the vehicle back to the dealership every single week just to have the safety lights turned off manually. Driving a vehicle with an active, un-diagnosed braking and crash-system fault is a major safety liability and makes the vehicle dangerous to operate. The manufacturer and dealer have failed to resolve this safety defect under warranty."

2022 Lexus IS 300 Transmission & drivetrain Engine & cooling Fuel system

Sudden engine stalling in the middle of a highway with extremely heavy traffic and stopped in the center lane. Needs to wait inside the car with a passenger in a very scary, tense situation and exposed to serious accident, until a towing arrive for about 1.5 hrs later. The car was towed to the dealer. Since I was in the middle of a highway, I wasn't able to exit the car to verify the car. But, the engine stalling was compatible with fuel delivery starvation. The fuel tank was full. The starter spin and electric...

system was functional, so electric voltage was not an issue. No check engine light on, no alerts messages, nothing. Just suddenly engine power loose, stalling and the engine stop. Check engine light on after a lot of cranking. Never fire back.

2022 Lexus IS 300 Brakes Engine & cooling

Unknown. Clicking sound coming from the passenger side of engine compartment by the vacuum pump. It occurs on cold starts and with the vehicle under load. I have video evidence of the sound. Not sure if it's related but my breaks sometimes feel like they are not gripping as much

2021 Lexus IS 300 Engine & cooling

The Oil Housing Cap cracked during an oil change on my 2021 Lexus IS300. This occurred at my mechanics shop. I would have taken the car to the dealer but the cost for an oil change is double. The mechanic charged me for the part $55.25. When he went to purchase the part from JM Lexus, Sample Road, the parts person said this is a problem that should have been resolved. I called the Parts Manager at JM Lexus to verify this information. He stated that the part is weak and cracks and that this part needs to be...

replaced a few times a month. I wrote to the Executives at JM Lexus and they refuse to reimburse me because the car was not serviced there, however, the bigger problem is that this part needs to be retooled and owners recalled for replacement. For those in cold weather, could this part crack and leak oil? Will I be charged every time I get an oil change because of this defect?
