My battery voltage is running higher tHan 19 volts all of a sudden. Anyone experienced this? What was resolution?

Your alternator might be trying to keep a dying battery charged. A lot of auto parts stores will do a free battery load test and charging system test.

Likely a bad cell in the battery
I had this happen before and replacing the battery fixed it after having it load tested(which of course confirmed what I already knew)

Why do you need to reply the same as me? A bad battery in almost always caused by 1 or more cells being dead. You cannot change cells in Automotive batteries.

Did you ever think maybe it was to confirm to the op by giving a second opinion?
Gees chill out
I know you can't change the cells in automotive batteries no need to be obvious about it

Just keep patting yourself on the back and keep up the useless replies to boost your numbers. We understand...

If it is not a battery problem, then the voltage regulator is going out in your alternator. It regulates the amount of voltage that goes to all of your appliances. Our alternators ususally last around 100-120k miles, but somehow mine got about 200k before having issues. A new alternator will run you 140-200$ and you can easily do it yourself. Barely loosen the serpentine belt, remove the bolt that holds the alternator on, take it out, put the new one in place, put the bolt and belt back on, tighten the bolt and belt and bam you are good. Unplug battery before doing any electrical work on your vehicles. I am about to do mine here when I get the money together. Also I believe the ESV uses the 160 amp alternator versus the 145 on the base models, I could be mistaken though. Make sure you get the right alternator.

Lepper mine failed at 203,000(roughly)

The 05 has a separate brain the works the alternators charging circuit it is independent of the pcm
