Open the full vehicle complaint log (all categories)I was in the middle of a 1 hr long drive and my DEF gauge went from 2/3 full to empty nearly instantly. I received a message on the dash that said my speed would be limited to 5 MPH in 200 miles. Thankfully, I was within easy driving distance to a dealer, so I dropped if off yesterday (still waiting for their assessment of the issue), but what if I was in the middle of nowhere, and couldn't get to a dealer before that 200 mile limit was reached? What if the dealer couldn't see me for weeks/months which is not uncommon these days? These emissions control systems have gotten absolutely out of control and change needs to happen. 2026 RAM 2500 Laramie Mega Cab w/ approx 1,650 miles (yes, one thousand, six hundred and fifty miles)
