2019 Chevrolet Silverado Speed Control & Cruise Problems

On Sunday, April 12, 2026, at approximately 5:00 PM, I experienced a sudden and complete engine failure while driving my 2019 Chevy Silverado equipped with the 6.2L V8 engine. Without warning, the vehicle lost all ability to accelerate, creating an immediate and dangerous situation for myself, my family, and surrounding drivers. I was forced to rely on the vehicle’s remaining momentum to maneuver to the side of the road, all while other drivers honked as I attempted to merge with no engine power. This incident caused significant stress and posed a serious safety risk. My vehicle had to be towed home and then to [XXX] Casa Chevrolet at [XXX] . After inspection, the dealership informed me that the engine requires a full rebuild, despite the vehicle having only 115,697 miles. According to the dealership, the engine shows **no compression on all cylinders**, **crankshaft and camshaft compression failure**, **pistons coated in oil and fuel with visible damage**, and a **non‑functioning timing chain likely due to a broken guide**. These findings mirror the exact symptoms currently under investigation in GM’s **EA25007** inquiry involving the 6.2L V8 (L87) engines in 2021–2025 GM trucks and SUVs GM has already issued a major recall affecting nearly **600,000 vehicles** due to defective connecting rods and crankshafts that can cause sudden engine failure, stalling, and potential fire hazards. Although my 2019 Silverado is not included in the recall, it is experiencing the same catastrophic engine failure associated with the defective components identified in the investigation. The dealership has quoted me $10,000 for an engine rebuild and has refused to assist with the cost. I have also filed a complaint directly with GM, as this failure presents the same safety risks and mechanical defects acknowledged in the recalled models. This sudden engine failure placed my family and other motorists in immediate danger, and the lack of w INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lifter randomly went bad while driving down highway. Safety concern is being put into low power mode on an interstate and vehicle running rough. No warning lights and perfect performance before it happened.

TURNED ON TRUCK AND GOT MULTIPLE MESSAGES, "SERVICE ESC" AND "BRAKE SYSTEM FAILURE - SPEED LIMITED TO 62 MPH." BRAKING WAS EXTREMELY LIMITED - EVEN AT HARDEST EFFORT, TRUCK STRUGGLED TO COME TO A COMPLETE STOP. TRUCK HAS 6700 MILES AND ALSO BRAKE PADS ARE REPORTING 14%/18% LIFE LEFT WHICH IS INNACURATE BASED ON AMOUNT OF DRIVING.

I HAVE LOST POWER TO MY BRAKES ON 4 ISOLATED OCCASIONS IN THE SPAN OF A MONTH AFTER PURCHASING THIS NEW VEHICLE. ON EACH OCCURRENCE THE SERVICE TRAILER BRAKES, SERVICE ESC, SERVICE SPEEDS AND I WOULD SMELL BURNING UPON EXITING THE VEHICLE AFTER OPERATION. ON 3 OF THE OCCASIONS I EXPERIENCED THIS ISSUE WHILE STATIONARY AND UPON STARTING THE VEHICLE. ON ONE OCCASION I WAS OPERATING THE VEHICLE AT ROUGHLY 60 MPH AND ENGAGED THE BRAKES AND LOST POWER TO THE BRAKING SYSTEMS.

SERVICE ESC,SERVICE TRAILER BRAKING SYSTEM, BRAKE SYSTEM FAILURE 62MPH TOP SPEED AND A CHECK ENGINE LIGHT. HAVE ANOTHER APPOINTMENT AT DEALER AFTER RECALL FOR ESC BRAKE MODULE HAS BEEN PERFORMED

I TOOK IT TUESDAY 12/17/19 IN FOR AN OIL CHANGE AT 4K MILES TO GET UNDER 7K SERVICE. FOR MY 2019 HIGH COUNTRY. AS I WAS NOTIFIED I WAS DUE FOR AN OIL CHANGE. I LOOKED ON ONSTAR. SAW THERE WAS A RECALL AND FIGURED THEY COULD TWO THINGS AT ONCE. COME TO FIND OUT THERE WERE THREE RECALLS. WHICH I GET IT, THINGS HAPPEN. I GET IT HOME TUESDAY NIGHT NO ISSUES. THURSDAY 12/19/19 AROUND 6 PM, AS I WAS BACKING OUT OF MY DRIVEWAY AND IT WOULDN'T STOP. I HAD TO STAND ON THE BRAKES. I AM 6'2' AND 300 LBS. I WAS ABLE TO GET THE VEHICLE IN DRIVE AND AGAIN, THE VEHICLE WAS NOT EASILY STOPPING. I HAD NUMEROUS DASHBOARD DISPLAYS. I TOOK PICTURES OF THE DISPLAYED ITEMS. I CALLED RICK HENDRICK CHEVROLET AT 6:53 PM ON 12/19/19 AND SINCE I LIVE CLOSE DROPPED IT OFF AT THE DEALER, AS I WAS HEADED OUT OF TOWN SUNDAY AND WANTED THIS FIXED. SO.... HERE COMES THE ISSUE BESIDES IT NOT STOPPING THAT I AM EVEN MORE FIRED UP ABOUT! THE SERVICE GUY, CALLED ME FRIDAY MORNING TO SAY THEY CAN'T FIND ANYTHING WRONG. NOW, WITH THE DISPLAY SAYING SERVICE ESC, TRAILER BRAKE SYSTEM, AND BRAKE SYSTEM FAILURE NOT TO GO ABOVE 62 MPH, I AM PRETTY SURE IT TRIGGERED AN CODE AND WOULD BE IN CODE HISTORY. I TOLD HIM I HAD PICTURES OF THE DASH DISPLAY AND THAT THEY NEEDED TO CHECK THE CODE HISTORY. HE TOLD ME AT ONE POINT IT WAS THE VACUUM, BUT THEN TOLD ME THAT THE VACUUM WAS AN ISSUE WITH LAST YEARS MODEL. AND THAT HE WAS HAVING HIS MASTER TECHNICIAN LOOK AT IT. AROUND 4 PM ON FRIDAY, WITH A FAMILY TRIP COMING UP SUNDAY 12/22/19 AND NOT HEARING ANYTHING I CALLED A FEW TIMES TO FIND OUT IF I NEEDED TO RENT A CAR OR THEY COULD GET ME A LOANER. I GOT A CALL AROUND 5:13 PM ON 12/19/19 TELLING ME IT'S READY AND THEY REINSTALLED THE SOFTWARE AND THE MASTER TECHNICIAN DROVE IT. SAID HE IS COMFORTABLE. I WAS SCARED THEN AND SCARED NOW TO PUT THEM BACK IN THAT VEHICLE.

THE MOST RECENT ISSUE OCCURRED ON OR ABOUT 11/15/2019 WHEN TRAVELING ON THE HIGHWAY AT APPROXIMATELY 65 MILE PER HOUR, THE VEHICLE HAD AN ENGINE LOST OF POWER. POWER REDUCED IMMEDIATELY AND ALL OF A SUDDEN WHEN MOVING IN THE 2 LANE ON A HIGHWAY INCLINE. INCIDENT ALMOST CAUSED A FATAL ACCIDENT. PREVIOUS LOST OF POWER ISSUE WAS TAKEN TO THE DEALERSHIP AND I WAS ADVISED THAT IT WAS A THROTTLE BODY COMPONENT THAT WAS COVERED UNDER WARRANTY SERVICE TOO. ON OR ABOUT SEPTEMBER 14, 2019, THE VEHICLE LOST BRAKE FUNCTION WHEN EXITING OUT OF A SHOPPING CENTER ONTO A MAIN STREET. THIS TOO ALMOST CAUSED AN ACCIDENT AS THE TRUCK WOULD NOT STOP DESPITE USING THE EMERGENCY POWER BRAKE. ALL INCIDENTS HAD MY CHILDREN PRESENT.
