While driving on interstate towing empty 12' trailer, the engine stopped and received stabilitrack message and transmission too hot. This happened again after letting engine cool down. Had the tramission fluid changed two days later. Dealer just stated their was a loss of communication with the engine. One week later received transmission hot, idle engine message on the interstate while hauling the same trailer with only a riding lawnmower. Pulled over for 30 minutes and drove the rest of the way home at a reduced speed. Highway speed was 70 mph until it overheated, then drove 50-55 mph to get to my destination trying not to let transmission temperature over 220.

The plastic radiator has cracked and is leaking coolant heavily. Truck still under powertrain warranty by GM is only offering to cover 20% of the $1,823 repair cost. I noticed it when stopped to get gas, the vehicle leaking approximately 1.5 gallons of coolant while stopped for approximately 3 minutes. This caused the vehicle to overheat and needed to add coolant just to drive to shop.

Transmission shifts hard from first to second/second back to first. I noticed this about a week after purchasing truck. Shifts hard mostly in 2wd, not so much in 4WD or hauling/towing. Leaf springs and shackles have squeaked since day one of purchase. Engine oil pressure is at 12-15psi at idle and will not exceed 32-35 psi under normal conditions with or without a load. I've changed the oil filter and oil pressure sensor multiple times. There also seems to be a chirp/tick coming from the passenger side of the engine compartment. I've been trying to narrow it down for the last few weeks. Seems to be something going on in the engine itself or possible the ac compressor. Truck has 42,450 miles

Its a brand new pickup track when I got it after one year a issue came up with caramel looks like leaking under the truck, radiator coolant got mix with engine oil. No warning light, engine might overheat or engine might lockup. The dealer replaced the radiator and just flush the line. I heard so many complaint about this issue. But never heard any recalled.

Starter is bad, drags when cold or its drawn the battery down to where it won't start. Jumped it once, the dealership replaced the battery but that 650 cold cranking amp is not big enough for the starter. We need to go to a 1000 cold cranking amp plus a 200 amp alternator. Or we could just replace the starter with a good one.

Vehicles engine and ignition shut off while turning right. Engine can be restarted immediately. This has occurred 3 times in 3 weeks (1090 miles) unexpectedly while traveling at low speed. One time while entering a roadway from a parking lot, one time while pulling over to park and one time while turning off of a highway off ramp. The dealership, healey brothers of middletown, NY attempted to recreate the problem, but was unable to do so and has no answers as to what could be the problem.
