General Motors LLC (GM) is recalling certain 2019-2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The battery positive (B+) cable rings may have been manufactured with excessive glue, potentially causing an intermittent electrical connection between the B+ cable and alternator.

THIS TRUCK DOESN'T EVEN HAVE 7500 MILES ON IT. IT WAS DRIVEN TO WORK THIS MORNING WITHOUT ISSUE AND PARKED FOR APPROXIMATELY FOUR HOURS. UPON ATTEMPTING TO START IT FOR LUNCH HOUR THREE MESSAGES SHOWED UP IN THE DIC: 1) 'SERVICE ESC', 2) 'SERVICE POWER STEERING', AND 3) 'PARK ASSIST OFF'. IN AN ATTEMPT TO EVALUATE I PULLED THE TRUCK FORWARD AND THE AVAILABLE STEERING REFLECTED AN INOPERABLE POWER STEERING SYSTEM. I BACKED INTO THE SPOT AGAIN AND SHUT THE TRUCK DOWN. I STARTED THE TRUCK AND SHUT IT DOWN FOUR OR FIVE MORE TIMES WITH THE SAME MESSAGES PRESENTED (ALTHOUGH PARK ASSIST STOPPED APPEARING) AND ONLY ON THE LAST TIME DID THE MESSAGES GO AWAY AND POWER STEERING RETURNED.

2020 SILVERADO RST 1500 4X4 ALLSTAR WITH 8 SPEED TRANSMISSION. AT 4,000 MILES DEVELOPED A SHUTTER IN TRANSMISSION AND SLIPPING AND HARD SHIFTING MAINLY BETWEEN GEAR 1-2. BAD ENOUGH WHEN YOU START FROM A STOP WHEN IT SHIFTS YOU FALL FORWARD. THE ACCELERATION PUSHES YOU BACK AND THEN IT JUST SLIPS TO NO WHERE TILL IT CATCHES AND GOES. CONTACTED SHOP AND WAS TOLD AT 1ST OIL CHANGED THEY WOULD FLUSH THE FLUID PER THE SERVICE BULLETIN. THIS MADE IT WAY WORSE. SHIFTING IS MORE ROUGH AND SHUDDER IS MORE FREQUENT. TOOK IT BACK FOR THE 2ND TIME AND HAD TO DRIVE WITH A TECH SO THEY COULD EXPERIENCE THE ISSUE. IT IS GOING BACK TO THE SHOP TOMORROW 1/11/2020 WITH ONLY 7,500 MILES WITH HOPES OF A NEW TORQUE CONVERTER. THIS SHOULD BE A RECALL AND RESULT IN A CLASS ACTION.

IN MAY I PURCHASES A 2020 SILVERADO. ON DECEMBER 05TH, 2020. I WAS DRIVING ON THE INTERSTATE HEADING HOME FROM MY SON'S FOOTBALL GAME . THE "SERVICE BRAKE SYSTEM" MESSAGE DISPLAYED ON THE VEHICLE'S DASHBOARD. BRAKING BECAME SLUGGISH AND STIFF. I INITIAL THOUGHT THE BRAKE FLUID HAD HAD LEAKED OUT. THE VEHICLE MAINTAINED POWER TO ALL OTHER SYSTEMS. ONCE HOME I CHECKED THE ENGINE BAY AND BRAKE CALIBERS AND FOUND THEM TO BE INTACT. AT THIS TIME THE VEHICLE HAS 12,400 MILES. AFTER A INITIAL ASSESSMENT, WAS INFORMED THAT IT WAS DETERMINED TO BE A "COMPUTER GLITCH" THAT WAS EFFECTING THE TRANSMISSION AND BRAKE SENSORS. THE BRAKE MODULE WAS REPLACED AND TRANSMISSION "SOFTWARE" WAS UPDATED. THIS WAS COMPLETED ON DECEMBER 09TH, 2020. UPON COMPLETION THE TECHS CONDUCTING A "DRIVE TEST", AT WHICH TIME THE WARNING APPEARED AGAIN. MY VEHICLE REMAINS AT THE SERVICE DEPARTMENT, WHILE THEY "TROUBLESHOOT" THE PROBLEM. DUE TO THE VAGUE RESPONSES BEING PROVIDED BY THE DEALERSHIP SERVICE STAFF AND THE LACK OF AN ESTIMATED TIME LINE FOR THE COMPLETION OF THE REPAIRS. I BELIEVE THERE IS A MUCH LARGER ISSUE THAT THEY DON'T WANT TO REVEAL.

THIS TRUCK IS NOW ON ITS FIFTH CHECK-ENGINE LIGHT SERVICE FOR IDENTICAL FAILURES OF THE AUTO START/STOP FUNCTION. THE GM ONSTAR DIAGNOSTICS REPORTS INDICATE 2 FAILURE MODES, ONE WITH THE ENGINE/TRANSMISSION AND THE OTHER WITH THE LITHIUM-ION BATTERY. I HAVE SEVERAL CONCERNS. 1, I MAY BE STRANDED AT AN INTERSECTION WITH A VEHICLE THAT WILL NOT RESTART AND/OR HAS STALLED IN THE INTERSECTION AND 2, THE LITHIUM-ION BATTERY WILL FAIL CATASTROPHICALLY LEADING TO A VEHICLE FIRE.

THE 2019-2021 SILVERADO'S HAVE A MAJOR SAFETY ISSUE WITH THEIR REARVIEW CAMERAS AT NIGHT TIME. THE INFOTAINMENT SCREEN ON THESE VEHICLES DIMS APPROPRIATELY AT NIGHTTIME TO ENSURE SAFE VIEWING OUTSIDE OF THE VEHICLE, HOWEVER AT NIGHTTIME WITH THE INFOTAINMENT SCREEN DIMMED, WHEN SHIFTING INTO REVERSE THE SCREEN GOES TO FULL BRIGHTNESS AND MAKES VISIBILITY OUTSIDE OF THE VEHICLE ALMOST IMPOSSIBLE ON PARTIALLY LIT AREAS. THIS CAUSES SAFETY ISSUES AS YOU ARE NOT ABLE TO MAKE USE OF YOUR MIRRORS TO SEE OBSTRUCTIONS OR OBSTACLES. THIS IS FURTHER MAGNIFIED AS THE QUALITY OF THE REAR VIEW CAMERA AT NIGHT IS VERY POOR, SO THE POOR CAMERA QUALITY COUPLED WITH THE INABILITY TO EVEN USE THE VEHICLES MIRRORS TO SEE OUTSIDE CAUSES SAFETY ISSUES. MANY OTHERS HAVE COMPLAINED AND DOCUMENTED THIS SAME ISSUE AND HAVE RAISED CONCERNS WITH GM AND DEALERSHIPS TO NO AVAIL. THIS SHOULD BE AS SIMPLE AS A SOFTWARE UPDATE TO MAINTAIN SCREEN BRIGHTNESS WHEN SHIFTING INTO REVERSE DURING NIGHTTIME OR DARK CONDITIONS.

STUCK IN GEAR. RESTARTED TRUCK, RESUMED NORMAL OPERATION BUT CEL REMAINED. 2ND OCCURRENCE, 9865 MILES - 65MPH ON HIGHWAY GOING AROUND CURVE, TRUCK JUMPED VIOLENTLY CAUSING REAR END TO BREAK FREE SLIGHTLY, THOUGH I KEPT CONTROL. TRANSMISSION NOW SEVERAL GEARS LOWER AND STUCK THERE, TURNING 2400 RPM AT 65MPH. SAME THREE WARNING MESSAGES AND CEL. TRIED MANUAL TRANSMISSION MODE, BUT IT DISPLAYED NO GEAR INDICATION, AND THE +/- BUTTONS DID NOTHING. PULLED OFF HIGHWAY, RESTARTED, ALL MESSAGES WENT AWAY, CEL REMAINED. TRUCK RESUMED NORMAL OPERATION. 3RD OCCURRENCE, 9905 MILES (ON THE WAY TO THE DEALER) - I WAS STOPPED AT TRAFFIC LIGHT, FIRST IN A STRING OF CARS. LIGHT TURNED GREEN, I STARTED TO ACCELERATE, JUST INTO THE INTERSECTION, TRUCK JUMPED VIOLENTLY, SAME WARNING MESSAGES, STILL HAD THE CEL FROM THE LAST TIME. TRUCK WAS NOW STUCK IN A HIGHER GEAR, COULD BARELY GET THROUGH INTERSECTION. VEHICLE BEHIND ME NARROWLY MISSED REAR-ENDING ME, AND OTHERS WERE BLOWING HORNS AS I LIMPED TO THE FAR SIDE OF INTERSECTION. THIS IS A MASSIVE SAFETY CONCERN. IF ANY OF THE ABOVE SCENARIOS HAD OCCURRED ON SNOWY/ICY ROADS, I COULD HAVE INJURED OR KILLED SOMEONE, INCLUDING MYSELF AND/OR MY [XXX] YEAR-OLD. DEALER REPLACED TCM, BUT IS STILL NOTING "LOSS OF COMMUNICATION" CODES BEING GENERATED. A CHEVY ENGINEER HAS REQUESTED THEM TO INVESTIGATE THE WIRE HARNESS FOR DAMAGE IN A PARTICULAR LOCATION, SUGGESTING CHEVY KNOWS OF A MANUFACTURING ISSUE. IF THAT'S SO, AND CHEVY HASN'T ISSUED A RECALL - OR EVEN A TSB - THEN THIS POSES A STRONG CASE FOR NEGLIGENCE ON THEIR PART. ARE THEY WAITING FOR SOMEONE TO GET INJURED OR DIE BEFORE ACTING ON THIS?
