2007 Lexus RX Electrical system Problems

“The rear lift gate handle is melted and gooey. When I touch it to open the rear door, I get this gooey tar-like substance on my fingers. My dealer told me it requires a complete replacement of the door's electrical components to fix. Seems unusual that this is electrical, but if it is, then something is generating an unusual amount of heat to melt the rubber cover. My car is black, but it is stored in a garage...and the handle is covered and out of the sun.”

“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. …”

“The exterior lift gate button has become a black sticky gooey mess. It is concerning that an electrical issue could be melting the black rubber button. Found many other cases of this with Lexus and toyota sienna's online. Has something been done about this occurrence?”

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.”

“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. …”
