VEHICLE SPEED CONTROL
Vehicle suddenly went into Reduced Engine Power while driving in heavy traffic. Vehicle immediately began to slow down and although there was some throttle response it was difficult to maneuver through traffic to get to the side of the road. This event happened around the 31,000 mile mark. The Reduced Engine Power message came on, but I do not remember hearing an audible alert. Being a 40 year Automotive Technician for GM, I am familiar with pulling codes and replacing parts. I called the dealership to see if this was covered by warranty and was told no. After pulling the codes, I personally replaced the Throttle Body Sensor and the Accelerator Pedal Assembly, but the vehicle continued to go into Reduced Engine Power mode. I took the vehicle into the dealership and they diagnosed the cause as a corroded connector. The connector was replaced and the vehicle was returned to me. After a little over one month and less than 1,000 miles the vehicle is once again going into Reduced Engine Power mode. I can have my vehicle available for inspection if necessary.

There were no prior indications of the eminent failure of the tire. This was the first of two Goodyear Wrangler tire failures for tread separation within 300 mile of each other.

POWER TRAIN
The contact owns a 2018 GMC Sierra 1500. The contact stated that upon depressing the accelerator, the vehicle shuddered while upshifting. There was no warning light illuminated. The contact had taken the vehicle to a local dealer where they were unable to service the vehicle. The contact had also taken the vehicle to an independent mechanic who informed him that there was a TSB placed on the vehicle. He explained that the incorrect type of transmission fluid had been placed in the transmission which would cause the failure that he had experienced. The contact then called Sewell Buick GMC of Dallas (7474 Lemmon Ave, Dallas, TX 75209) where he was informed that he would be charged a diagnostic fee prior to the repair. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 45,000.

TIRES:BEAD, TIRES:SIDEWALL
All four OEM Bridgestone Dueler A/T P285/45R22 M+S tires are showing premature cracking in sidewall near the bead/wheel. The cracks appear on the full circumference of the tire and vary in length from short to several inches. Depth of cracking is estimated to be 1/16" and growing. The tires, with date code 2318, were on the brand new truck when purchased from the dealership in Aug 2018. The vehicle currently has 16k miles. Both the dealership and local Tires Plus chain have confirmed the issue, but there is not a suitable remedy. Bridgestone will not warranty the tires and replacement under the GM "warranty" is the same price as new aftermarket tires. I believe this is a pending safety concern.

I LEFT HOME TO GO TO THE STORE. WHILE DRIVING ON THE HIGHWAY MY SUNROOF EXPLODED. THERE WERE NO CARS OR TRUCK IN FRONT OF ME OR PASSING ME. NOTHING HIT MY TRUCK. IT SOUNDED LIKE A SHOTGUN GOING OFF INSIDE THE TRUCK. THE SUNROOF EXPLODED SENDING GLASS EVERYWHERE. I WAS DRIVING ON A 5 LANE HIGHWAY, IT WAS RAINING, BUT NOT A BAD STORM. THE ROAD WAS STRAIGHT AND IN GOOD CONDITION. IT HAPPENED SO FAST I DID NOT KNOW WHAT WAS GOING ON. I PULLED INTO A GAS STATION TO CHECK MY TRUCK. I FOUND GLASS ALL IN THE BED OF THE TRUCK AND MOST OF THE SUNROOF GONE. I HAVE TAKEN IT TO THE DEALER AS THE TRUCK IS UNDER WARRANTY. I WAS TOLD THE WARRANTY DOES NOT COVER DAMAGE AND SO FAR NO ANSWER IT THEY WILL COVER IT. I HAVE HAD THE TRUCK FOR ALMOST 3 YEARS AND IT IS NEARING THE END OF THE WARRANTY.

SERVICE BRAKES
CERTAIN 2018 GMC SIERRA 1500 DENALIS WERE ISSUED A RECALL FOR THE "ELECTRONIC BRAKE CONTROL MODULE". FOR MY VIN, IT DOESN'T SHOW THAT THAT ISSUE NEEDS TO BE FIXED (I JUST PURCHASED THIS TRUCK LAST WEEK), BUT IT INDEED DOES. WHEN COASTING AT A LOW SPEED ON A SMALL HILL, BRAKES ALMOST FEEL NON EXISTENT. GMC RECALLED MANY OF THEIR VEHICLES TO GET THIS ISSUE SORTED OUT WITH A SIMPLE, "SOFTWARE UPDATE". FOR SOME ODD REASON MY GMC'S VIN WASN'T UP FOR A RECALL WHEN IT CLEARLY NEEDS ONE, IM PLEADING FOR SOME HELP; I'M WORRIED FOR MY SAFETY BECAUSE OF THIS MANUFACTURER DEFECT. ANY HELP IS APPRECIATED, THANK YOU.
