Dear Sir or Madam. My name is [[redacted]], [[redacted]], [[redacted]] living in [[redacted]]. I bought my 2008 Lexus RX400h car, used, in 2014 at a non-Lexus dealership in the [[redacted]] where I used to live. My Lexus VIN is: [[redacted]]. I've been satisfied with the car..until today. The car had been running smoothly forever, and this morning while I was driving I came to a stop (red light) and the car suddenly shut down completely, including the loss of lights, and the whole dashboard went dark. Other cars...

behind me were honking their horns. I could not even turn on the hazard lights. After 1-2 minutes, all of the lights/warnings started coming on one after the other. I started the car again and run around three different errands without having further issues. I checked online to see if other owners had experienced a similar situation, which is the case. One person said that there had been two recalls in 2011 and 2013, both related to the inverter module inside the hybrid system. Although, I called today a Lexus dealership, [[redacted]], located in [[redacted]], and I was told there are no recalls for the VIN number that I provided. Another owner said she/he went to a Lexus dealer in [[redacted]] and she was told it was a defect in the gutter drainage design and that water gets into the hybrid system. This is a dangerous and potentially catastrophic situation if the vehicle suddenly shuts down on a freeway/highway putting passengers in risk of harm, injury, or death. This is a horrific defect which Lexus should correct immediately with a recall before one of us ends up at the cementery. I am glad to know that organizations such as the NHTSA exist, and I will appreciate very much that immediate action is taken on this matter. Sincerely, [[redacted]].

2007 Lexus RX350Electrical system

Put key into ignition port and heard and felt a klunk. Key was then freely moving and connecting to nothing inside the ignition chamber. So vehicle would not turn over at all. Had towed to town closer to home. And Currently having towed to mechanic shop for further evaluation. The only symptom the car was having previously was a mysterious scratching sound coming from what sounded like the right side of the hood near the firewall. Took to mechanic and he drove the car and heard the sound but could not pin...

point it, said nothing was scrubbing the fan or anything else he could see. And to bring it back if it got worse. Never did we think it was the starter nor the ignition chamber. The only way to know now....is to replace it and see if that noise is still there. There were no other warnings. The danger in this is being stranded. Still needs to be evaluated by mechanic.

2010 Lexus RX350Electrical system

The speakers in my car made a loud noise and I thought someone hit my car. Ever since then it'll keep happening and it'll startle me when I'm driving. Sometimes my speakers would have really loud static sound and it's impossible to turn it off. It's extremely dangerous to be startled like that when I'm driving.

2007 Lexus RX350SteeringElectrical systemBrakes

Electrical system malfunction began (to my best calculation & recollection) in summer 2021 with the first of four battery malfunctions in one year. Each time, AAA discovered low battery response and recommended battery replacement. This time around, battery was replaced about two weeks prior, due to battery failure/AAA reporting would not accept charge. THE NEW BATTERY FAILED (8/3) and the starter broke while attempting to charge. Mechanic repaired starter and battery accepted the charge. No problem, right?...

Wrong. This driver drove about 30 miles and while driving, the electrical system shut down altogether. With I believe ALL WARNING LIGHTS LIGHTING UP, extremely dangerous situation. NO BREAKING, NO STEERING, NO WARNING. Fortunately, it occurred in a suburban residential area as opposed to the highway. SECOND tow to my mechanic and now, after a full week, no diagnosis, though the car has been running in the shop. This is an intermittent problem. I suspect the alternator.

2009 Lexus RX350Electrical systemAirbags

The dashboard in my car has been sticky and cracked for years. This became a safety issue and liability by posing a real risk in relation to airbags. One area of concern is the cracks will interfere with the deployment of the airbag. Either by triggering the airbag warning light or snagging the airbag on its way out. That puts my safety and safety of others at risk. This problem - cracked and sticky dashboards, has been confirmed by a dealer and warranty replacement program was available for short time back in...

2018. The company had to notify it's customers but I did not get any letters, emails or calls. Therefore I did not know about that warranty repair and missed it. The vehicle was inspected by a local mechanic and safety concerns were raised. The airbags warning lights first started to appear on and off about 2 years ago. I have contacted the dealer several times about dashboard warranty replacement program explaining that I wasn't notified but they did not offer any solutions or repair reimbursement.

Water gets into the body of the vehicle over time. Came outside one day after rain and my passenger carpet was SOAKED all my windows were up and my complex don't get flooded. Car smells like mildew in cabin! Middle of July I came outside and all the lights were on the dash, no rain the previous day or during, and car wouldn't start. Took it to the dealership and they can't explain how water got into my car but magically the sunroof drain was clogged with water.

2007 Lexus RX350Electrical systemBrakes

"Check vsc" system with accompanying continuous beep noise, brakes become hard to push/activate. This started a few weeks ago, and would happen intermittently, and progressively longer in the dysfunctional brakes phase. I had an employee at auto zone clear the code 2 days ago, but the problem started again, intermittently upon vehicle start, but would go away shortly, with normally responsive brakes. This intermittent issue occurs when I am driving, therefore this is a serious road hazard as my brakes become significantly less responsive when the problem occurs. In other words, this occurs when stationary and when driving, intermittently.
