Reviews of MOPAR battery

2020 Grand Cherokee. The ASS stopped working so I took it in and they said it was because the battery was dead. They replaced it under warranty. In less than a year the system stopped working again, I'm assuming the battery again. Looks like jeep's ASS DON'T work with Mopar batteries

I just replaced the Mopar original provided battery 2 weeks ago. This was after I was able to jump it and get it to the dealership. \nThen 2 days ago I tried to remote start it\u2026 no dice.\nGot in had acc but no start, no cranking just one click. \nTried to jump again and no lock. The brake locked up and couldn\u2019t be pushed more than a quarter inch.

I had the battery and MGU replaced under warranty already at 5k miles. I ended up purchasing an extended warranty through mopar that goes 8yrs and 90k miles for about $2,780-ish. It’s still a 5.7 hemi and city gas guzzler (15.7-17.2 mpg max). But on straight up highway I’ve gotten into the high 20’s in MPG.
