general problems of the 2009 Chevrolet Silverado 2500

While pulling a horse trailer up a small mountain, heard alarm, engine lost power and reduced engine power message came up as well as ck eng light. Vehicle would not go over 40 mph initially then went down to 30 mph. Struggled 15 miles at 20-30 mph to get it to my residence. Turned off for 15-20 minutes. Turned back on, ran normally but ck eng light was still on. Next morning, started up, ck eng light was off. Took to dealer. Said there were no codes and they had no idea what was wrong. I had to travel on a dual highway, pulling a horse trainer at 20-30 mph with my flashers on. Also had to turn across dual highway on at grade intersections, not knowing of the truck was going to have enough acceleration to get across the highway.

Tl- the contact owns a 2009 Chevrolet Silverado 2500. The contact stated that when you press the accelerator there is a few second delay before the vehicle responds. The contact stated that when the vehicle did respond the vehicle almost spent out of control. The contact also stated that when you release the accelerator, it takes a few minutes before it starts to slow down. The contact took the vehicle to the dealer and was told there was nothing that could be done to fix the problem. The failure mileage was 10 and the current mileage was 50,000. Rl.
