Driving at 70 mph when I tried to accelerate. Heard a loud bang from the exhaust and immediately started to lose power. I had zero warning that anything was wrong. Warning messages flashed and I lost propulsion. As I was pulling over the engine died completely and shut off. Purchased the vehicle on 11/25 and had 4100 miles on it. 6.2L Chevrolet ZR2. Dealer confirmed that that the crankcase failed which resulted in catastrophic engine failure. Currently waiting on new replacement engine. Lemon lawyers have sent demands to GMC. I've owned four GMC/Chevrolet since 2004. I no longer trust this engine to not die. I ordered a 2026 Ram RHO yesterday. Only pray that I'm not trading one bad truck manufacturer for another. Additional Details Edit

Sorry to hear of your misfortune, and I'm glad you were able to navigate the problem without an accident or injury. If you haven't already, you may want to try to report the issue to NHTSA. I would hope that catastrophic engine failure on the highway @ 70mph should be considered a safety issue for them.
I can't say from personal experience that you'll be happier with the RAM, but everything I hear on the Internets says that you're likely to not have any major powertrain issues throughout the warranty period as long as you do the proper maintenance. I've never been a Mopar guy myself, but it seems like it's the way to go at least for now if you're buying new.
Wish you the best on the new RAM.
