HVBATT Errors

[cyberHoward]

They keep telling me this is nothing, but I am getting multiple times and hour HVBATT MIa. See the attached log. It has been increasing since December. Yes, my screen needs cleaned

Left Vehicle Controller lost communication with HV Batt. Mine started that last Saturday that sets no alerts, so you’re unaware. Everything was working fine.

Plugged in and charged overnight from 60 to 70%, where I normally charge to. Was taking a ride to pick up a trailer I wanted to buy Sunday morning, so increased to 80%. Not able to charge.

3 Alerts HVBATT. (Unable to Charge, Limp Mode, Voltage Sense Failure) Scheduled first appointment available July 16. SC opened 8 AM Monday morning, accessed remotely and app showed Parts in Transit. Called today to see what parts was ordered in case I need to remove rack to access PCS. Battery ordered...

Removed running boards to prevent techs from running into them on lift, shut Bluetooth off on phone to prevent waking to save power for the one hour trip to SC in 16 days. Alert also states “may clear on next drive” as well as “may not restart”. We’ll see.

Appears every time the vehicle was driven the 27th it set the code you’re referring to. Then next day after charging fine the same code was set waking to charge, (9:33:53) when the other HVBATT Alerts gave me the first clue something was wrong. Issues related? No PCS warnings. Believed to have latest version.

2026 Premium, 10/25 build, VIN 87,4xx with 3,236 miles.

I’ve been getting that message too just not as frequent. Can still charge. Tesla Service also told me it wasn't an issue.

I have seen these alerts in my service menu as well constantly for the past few months. Was in service for another issue on Monday and SC said it’s not an issue…….

Many times it is just communication from what I read in above threads.

I have the same errors plus a pcs error. I have an appointment on the 20th. I messaged service and asked if the pcs error means the pcs will need to be replaced, they said yes. I didn’t ask about the Hobart errors but it’s on the request as well, so I guess I’ll find out on the 20th.

SC has my CT, waiting for a battery shipment
Replacement

Imagine if I don’t actually need one
Hope these guys know what they’re doing

The SC is replacing you battery pack because of just these errors?
