Ordered battery for mine with those same codes. The voltage sense harness or connection inside battery case is the problem, (diagnosed remotely) so entire battery is replaced, treated as a sealed unit at Service Center.
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...
Same here; 3,236 miles on a ‘26 Premium. VIN 874xx. Scheduled service appointment for July 16 and app shows Parts in Transit.
No PCS Alerts, supposedly using the latest PCS without known issues. (10/25 build) Assuming the Voltage Sense Harness integral to battery pin/ connector issue.
Test drive a Model Y to see if she feels the same? Perhaps if she drives, the feeling from controlling the vehicle herself will register in the brain, getting used to movement without sound?
Yes, this is the first generation and I installed the swivel mount above the dash mounts instead of below them. This raised the screen to about 1/2 inch lower than original. Perfect height for me at 5’6.
The plastic cover for rear of screen won’t work, but not noticeable unless you tilt as far...
My 26 AWD received it with original update, and has shown “Optimized for front seat occupants”, but hear no difference. 5 foot six with 68 year old ears. I think I need a booster seat.
Opened audio screen during second drive (2026 AWD Premium) since installed to find it asking for audio sound off, that there was too much noise to calibrate. Shut audio off, as well as climate for a quiet cabin.
Calibration went from 20% to 40, eventually 60% to 80 within 10 minutes. Was...
First drive with Road Noise Reduction on, no highway driving, no audio on, no difference noticed toggled on and off in self drive. But after parking twice and 10 miles sounding normal, pulled into a large parking lot and heard a rumble type sound at slow speed, like knobby tires, looked at tire...
2026 model year 874xx AWD with core wheels. October ‘25 build. Software update 2026.2.9.1 added Active Road Noise Reduction immediately and was toggled on. Have not driven since update.
I would dial amp charge rate down to prevent the half of inverter still working from maxing out at 24. IF heat from high amperage is breaking a component down, that may extend its life to get you through the time element.
It would be interesting to find if the failures have been charging with...
