So around a week ago, I got into my 2007 ES350 and realized that the battery light was on on the dashboard, so I assumed it was the battery going bad since it hadn't been changed in a while. So I went to my local auto parts store, and they told me that my battery was going bad and had only 15% life left, so I bought and installed the new battery. Around 3 hours later, I was driving and the lights on the dashboard, interior lights, lights on the radio, ac control panel lights all started to flicker as if the alternator was giving out and not charging the brand new battery. Right after i noticed this, the car died and would not start. So after ending up at home with the car, I ended up deciding it was the alternator and I replaced it myself the very next day. The car worked perfectly for about a week, and this leads me into my current problem. This morning it started up perfectly, no problems. After about 10 minutes, every single warning light on the dashboard turned on: check engine, airbags, vsc, traction control, and the battery. I got to work and turned the car off, and tried to turn it on again out of curiosity, and it wouldn't start, in a very similar way to what was happening with the broken alternator. After work, it started no problem again, however after about 5 minutes it started to show me all of the warning lights again, and the dashboard and gauges turned off entirely. The strange thing this time is that the engine still runs perfectly. I'm almost ripping my hair out here trying to figure out what could be wrong because I've checked practically every fuse in the car, bought and installed a brand new battery and alternator, and i'm still having problems with the electrical system. If someone could recommend something I will forever be grateful.

 

rodents chewing wiring harness somewhere?

 

Hello
I have a 2007 lexus es350. when accelerating from stop, it will randomly shut down completely for a split second, like half a second seriously. ive taken it to my mechanic and dealer and mechanic cant find anything wrong with it. Dealer said battery voltage was low, so i replaced battery and it is still happening. Car has 163,xxx on the dash. does anyone know what this could be? like mentioned before, the car will completely die, engine, trans, dash goes black etc and then it comes back to life.

Please advise

 

When you have it running, check the voltage at the battery. Make sure it is above 13v. If it isn't then you could have a bad alternator

 

Any trouble codes?



That may be the ECU going south.

 

The ECU in the car should have recorded the incident for a loss of power I would think...can you scan the car?
