2011 Sequoia had interior light left on which drained the battery. Unsuccessful at jumping it, so replaced the battery. Engine check light was on and would not go off.
It would lose power and die driving down the road. Stranded twice.
Took to a local shop, which kept it overnight to test for drains, claiming battery was good.
Stranded again, and the local shop now said it needed an alternator and the battery had dead cells. The shop replaced alternator, battery, and now three weeks later it won't crank again.
On the first trip had the shop check for any safety issues and they said it needed two of the three catalytic converters replaced, which did improve my gas consumption.
Any clues ??
Thanks
