The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.

Service brakes

23 reports2 crashes
“I am reporting a serious and potentially dangerous braking issue with my 2007 Lexus RX400h. The vehicle currently has approximately 126,296 miles. While driving, the vehicle emits a continuous and intermittent warning beeping sound. At the same time, the braking system becomes unreliable. The brake pedal becomes extremely difficult to press, requiring excessive force, and the vehicle does not respond consistently when braking. In addition, there are instances where the vehicle appears to brake unpredictably or inconsistently, which creates a significant safety hazard for myself, passengers, and other drivers on the road. Based on my research, this issue appears to be related to a known defect involving the ABS brake actuator assembly. Lexus previously issued a warranty enhancement program for this component due to internal malfunctions that affect brake pressure and system performance. However, this issue was not issued as a formal recall tied to VIN eligibility. Despite my vehicle being under 150,000 miles, I have been informed that I may be outside the time-based warranty window, and no active recall is listed for my VIN. This defect directly impacts the…”

Structure

18 reports1 crash
“I saw on the internet while I was looking for new mats this year my Lexus RX 350, 2007, vin [XXX] was recalled for the dashboard until May 2017. During 2013 through 2018; my husband left me for my friend; both my sons were shot in different cities; one in Nashville, and one in Denver Colorado. The one in Nashville, was shot 10 times by his roommate who forgot he had a roommate. Fortunately, he turned around so his laptop in his backpack got the bullet which would have killed him. He was left with a dominant disabled arm. He had just come back from Las Vegas working with Jason Aldean as a cameraman and saw the bloody massacre from the shooters. My oldest lives in Denver. He was shot and killed by the police on a domestic call. They overreacted. My ex-husband would not let me come to the funeral or visit the son in Nashville when he was hurt. I was not able to focus on anything else during that time. When I saw the recall on the Internet this year, I called and requested a reprieve. I was turned down. I wrote a letter to Lexus. Again I was turned down. I am [XXX] and [XXX]. I’m still driving my Lexus 2007 and plan to the rest of my life. I didn’t see the mail…”

Electrical system

17 reports
“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.”
