OK to Drive with Caution, Traction Battery Fault Detected.
Well, it has 1,067 miles, no problems so far, but when I went to start it this afternoon:
"OK to Drive with Caution, Traction Battery Fault Detected" appeared in the left side of the dashboard display.
Tried it twice. Repeatable. When through the left side steering wheel roller menu to Alarms (under info?) and it said:
Not Available (not None).
Checked the cellphone app for Vehicle Health, AOK.
So I drove it home.
It accelerates, regens just fine.
Got home and shut it off and tried again. Same ERROR.
So I plugged it in to charge it fully (it was at 75%) and will try again.
I called the Jaguar Assistance number on the Remote App, and they cannot diagnose (GM spoiled me, they can read the ECM codes immediately through OnStar).
Called Anaheim Jaguar (my dealer, Newport Beach is not really up to speed on i-Paces).
So... If the error persists after 100% charge, I make a service appointment. I should be able to drive it there.
I honestly believe it's a software issue. The boot sequence was weird when I first got the code.
The car coasts in neutral, operates in R and D, and regens hard. If the traction battery was faulty normally it won't regen or allow you to charge it. Normally it won't allow the traction battery to engage at all.
So now it's my turn. Hope I'm right. A battery replacement is a major undertaking requiring many special tools on most EVs due to the battery weight.
I was going to let my wife take the car to Las Vegas today, but she decided to take her car. I am very glad I didn't try and talk her into it.
