October 20, '23 Our recent DEAD STOP! Whistle blower! Did you know that when the alternator goes out on a Lexus, that the car draws down energy from the battery to keep the car going? That's only for about a mile or so, then the car shuts down! You can't steer and THE ENGINE STOPS RUNNING and you have no power as you come to a dead stop, whether on the freeway, or one lane mountain pass road, where we would have been later. What would we have done? Scary! Luckily, our Lexus stalled on a city street nearing our on-ramp to the freeway. (needing to be towed.) Lexus has a serious engineering-defective-design-flaw that probably is responsible for accidents. Thanks, [XXX] . Pass it on please!
