1 Battery Dead problem of the 2007 Lexus RX

Failure Date: 08/06/2022

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.

2 Battery Dead problem of the 2010 Lexus RX

Failure Date: 08/13/2009

Purchased a 2010 Lexus 450h in August of 2009 and less than one week after purchased my wife parked the car for two hours and returned and the battery was dead. Lexus sent someone to jump start it and we brought to service at the dealer in carlsbad, CA. The next day. They checked it over and said that the onboard computer never found a problem and that all appeared to be perfect. They doubted that the car was ever jump started but then called the towing people and found that to be true. They gave me a readout showing the car was fine and that the onboard computer showed no error.
