Bad MGU

[troymv505]

My dealership said to keep driving my 2021 RAM 1500 while waiting on a new MGU that's failing. I'm on my 2nd new battery in 2 months now and I suspect the MGU is causing new batteries to fail. For those that had to drive their vehicles with a failing MGU will it keep ruining batteries?

Yes ..took 9 weeks to get my parts..the repeated discharging and recharging with battery charger at night ruined my battery. Btw the MGU is covered under 8 yr emission warrenty..No charge to replace my 21 Bighorn Hemi E Torques
