2016 ES 300h Intermittent Start Problem
I have a 2016 ES300h and about 110,000 miles on it. Just 4 days ago (1/8/22), I had my first experience of not being able to start the car. On that occasion, I had driven more than 1 hour on the thruway. Parked the car for about an hour. When I tried to leave. The "Ready" light would not come on. All other lights and indicators came on as usual. The map was working too. After a minute or two of trying, I was able to restart and drove off. Thinking that the 12 V battery was the culprit. I researched a little and discovered that there is no good alternative to the OE version.
Subsequent day was a Sunday. The same thing happened again, but I was able to restart after a few attempts. On Monday, I had mechanic test the battery and he suggested that I replace it. So I was going to get the battery from the dealer (almost $400). Then I encounter another occasion that the "Ready" light wouldn't come on. On that occasion, I was fortunate that a kind person helped jump the car. Thinking that would start it up. No luck. It was again a good 15 minutes or so of retrying with the jumper cable connected and the jumper car's engine revved up. Finally the Ready light came on.
This morning (1/12/22) I replaced the battery at the dealers, and immediately after that, I couldn't start the car again. They took it in and could not find any fault codes or anything suspicious. So that tells me that the battery doesn't seem to be the reason.
Ultimately they suggested that I remove the Allstate insurance Drivewise device that is plugged in to the OBDII socket and see if the problem recurs. 4 hours at the dealer, they were kind enough to not charge me the diagnostic fee, still no concrete solutions.
It appears to me that replacing the 12V battery does not resolve the issue. Anybody has any other ideas? Thank you so much.
