CAMPINGCPL

I have a 2020 Silverado 2500. It's done it ever since I've had the rig

Replied to this thread in the problems thread but i think it's been deleted. Had the computer update for the DEF sensors, now exhaust brake works even less; only works when in tow/haul mode. Took in today for service. They had no updates, even called GM technical service line. Looks like not enough of us have reported.

I just had mine reprogrammed for DEF. my exhaust brake doesn't seem to come on at all now when not towing and I definitely notice the lack of auto grade braking. Will investigate further.

Got the update done at the dealer. Significant positive difference in both towing and driving.

Thanks! This is exactly what I was thinking, the brake tap. Loved towing with the cruise on. The 10 speed is amazing.

Greetings All. Wife and I bought a 32 foot travel trailer (6500lbs dry). Drove it off the lot with my 2017 Ram 2500 6.4L. Seemed fine. Take it for the initial camping trial and I thought the truck was going to explode. Transmission got goofy and went into limp mode. The thing was 600 miles over Powertrain Warranty, FCA told me to pound sand. My previous vehicles were GM and I had several issues fixed under warranty - some thounds of miles beyond. Went and test drove a 2020 Duramax LT Z71. Fell in love.....and it has leather and butt warmers so wife was happy too! Took her out to Yellowstone and Teton for the holiday weekend. I am completely enamored by this machine. She surpassed all of my expectations. I could barely feel the 10 speed Allison shift. Coming back today throug all the passes and 50+mph wind gusts, she stayed on course. Set her on cruise control and off we went. I am interested if anyone has any tips for the exhaust brake. I used to run Ford and Medium Duty Durmax ambulances and the exhaust brake seemed to kick in if the foot was off the accelerator for some amount of time. Tbis truck I had to tap the brakes just right for it to kick on. Any ideas or tips? Happy to be back in the GM Family and live this Duramax!
