Hello. I just purchased a 2025 RHO. Drove home from the Dealer, 10 miles no issue. My wife drove it another 100 miles or so the next day to an event and back with no issues. The next day I drove it 55 miles to work with almost no issues. Getting on thr freeway at 4500 RPM's I got a cruise control error, an automatic emergency breaking issue, and maybe a few other ones. As soon as I pulled into the parking lot, I got a check engine light, all the same messages on the dash, and it was stuck in gear. Would not shift up or down.
When I left that day, the check engine light was still one, and every time I hit 4500 RPM's it would get stuck in gear until I pulled over. Then it would shift like normal as long as I didn't let RPM's climb to 4500. The next day on the way to the dealer it went into limp mode and every system had a fault. Suspension fault, cruise control fault, braking fault etc. It would barley go 15 mph. I disconnected the batteries , reconnected them and it drove well enough to get to the dealer. CEL never went away.
The Dealer stated the Auxiliary battery was failing a load test , so they replaced both batteries. They claimed that solved the issue and went ahead and replaced a leaking CV boot. (truck only had 200 miles and I've had it 2 days). They called shortly after and said it wasn't fixed and that it was having communication issues. The next day it was believed to be fixed so I went ahead and picked it up. Not even 2 minutes down the road, I hit 4500 Rpms and the check engine light came back and it chimed all the faults, and stuck in gear. I drove it back to the dealer and currently waiting. Sounds like a cam issue. They swapped sensors and that didn't fix it. Hoping for some answers soon.
