2015 Chevrolet Silverado Speed Control & Cruise Problems

I purchased a Brand new Chevrolet Silverado 1500 LT Z71 in2015. While still paying on this vehicle I had an issue with the engine bogging down and it would almost die. It would jerk and shake terribly to the point it just shut down. I took to Royal Chevrolet and they found that it had a broken Valve spring on Cyl 7. This went on and on they had this vehicle for a total of almost 7 months before they put 1 last engine in it. The 1st thing I did was drove down From Michigan to North Carolina to visit my daughter. Plenty of Mountains and a lot of driving as I drove 14 hours straight by myself. The engine that they had just put in started Chugging and choking and it stalled on the highway going through the mountains and I was hit in the rear end and the other driver never stopped. I managed to get it running again. Prior to leaving for North Carolina I ordered what they call a tuner where I could deactivate the AFM system and stay in 8 Cyl mode at all times. I had it sent to her house. I installed the program. Keeping in mind #1 I was rear ended. And every single time there was an issue it was Cyl#7 on all the previous engines. I talked to the Lead man at Royal chevrolet about all the issues and he said they know all about it and its a joke. They tried it on Cadillacs back in 1975 and recalled every one of them and turned it off. On my way back home not 1 single issue in fact and I sill have it displayed on my dashboard I actually got 26.2 Miles per gallon in V-8 mode in the mountains. I have driven to NC every year since before I even owned that truck and have never seen milage before or since. The AFM system is nothing but a ploy to get people to buy junk. Could someone been killed? Most certainly. I told the manager 1 more engine and I have a Friend cut stickers of lemons out and put at the main 4 corners in our town. I still have that truck and currently have 128,000 miles on it and I had to pay $600.00 to fix it myself. And GM thinks its a joke. I called GM

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 45 MPH, THE CHECK ENGINE INDICATOR ILLUMINATED. THE VEHICLE STARTED TO DECELERATE WHEN DEPRESSING THE ACCELERATOR PEDAL. THE VEHICLE WAS TAKEN TO THE DEALER, BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 33,000.

TRANSMISSION PROBLEMS. WHEN REVERSING UP A DRIVEWAY THE TRUCK WILL STALL AS THE GAS IS PRESSED IT WILL REV UP BUT NOT GO ANYWHERE, THEN JUMP INTO REVERSE AS IF THE PETAL WAS FLOORED. ALSO SOME TIMES WHEN ENTERING THE HIGHWAY THE TRANSMISSION DOESN'T SHIFT INTO THE CORRECT GEARS ALSO JUMPING INTO GEAR WHICH COULD CAUSE ACCIDENTS.

A REPRODUCIBLE CONDITION EXISTS WHEN THE DRIVER REMOVES THEIR FOOT FROM THE GAS PEDAL, THEN QUICKLY ENGAGES CRUISE CONTROL, THEN PUSHES THE MINUS (-) BUTTON REPEATEDLY TO DECELERATE THE CRUISE CONTROL, THAT THE VEHICLE CRUISE LOCKS UP AND FLIPS BACK AND FORTH BETWEEN THE DESIRED SPEED AND THE ORIGINAL SET SPEED, AND DOES NOT DECELERATE. THIS CAN OCCUR FOR SEVERAL SECONDS, WHERE THE DRIVER BELIEVES THEY ARE DECELERATING THE CRUISE CONTROL BUT IT IS LOCKED AT ITS ORIGINAL SETTING, WHICH COULD LEAD TO AN ACCIDENT.
