2019 GMC Sierra 1500 Electrical System

This truck needs 2500.00 in work to replace Electrical Harness after months of problems and evaporating leaks.

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving approximately 45 MPH, the message "Battery Saver Alert" was displayed on the instrument cluster. The contact stated that the battery gauge was reading 9V on the 12V battery. The vehicle was driven to a dealer. The dealer diagnosed the vehicle and determined that a battery tender was needed. The contact asked the dealer to check the 12-Volt battery which was replaced 2 years prior by the same dealer. The dealer diagnosed the vehicle and determined that the alternator needed to be replaced. The contact was later informed that the battery fuse also needed to be replaced. The vehicle was repaired. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 19V888000 (Electrical System); however, the VIN was not included in the recall. The failure mileage was 43,742.

Vehicle (2019 GMC Sierra SLT X31!Crew Cab 6.2 l gas engine) stopped running while driving down the road (Wednesday [XXX]. Tried to start truck - would crank over quickly but failed to start ( crank no start with no check engine light.) tried several times same result. Started after about 5-10 minutes and was displaying low fuel indicator even though we knew it had approximately 1/2 tank. We immediately put gas in it and it took approximately 1/2 tank to fill. Still no check engine light and confirmed no stored codes via onstar report. Drove the truck around for may 1hr and check engine light came on but was still running and did not stop running like it did earlier. On star reported ECM SYSTEM CODE P129F ( Fuel pump or fuel pump power control module). Long story short, put truck in independent repair shop I use. They diagnosed it was a defective fuel pump located in fuel tank. They told me GM technical support recommended to replace the fuel pump and fuel pump power and control module at a cost of ~$1325.00. It is my opinion this is a safety hazard and very similar if not exactly the same failure symptoms / modes as others have already reported. I requested to keep the failed parts and still have them in my possession. Please review and let me know if you need or want additional information .

When going to shut off vehicle, when you push the push start button the engine will turn off but the radio and all the instrument panel, gauge lights, and dinging noise are still on. It states on the screen to shift to park. The vehicle is in park and even sometimes has the parking brake on. It can stay on from 1 minute to numerous minutes, which is only running my battery and other things down on my truck. This has happened daily.

There is an issue with the drivers door locking mechanism. Something between the electrical and the mechanical components that lock and unlocks the door keeps breaking. So far you can always unlock the door manually by pulling the door handle but it sporadically will not lock or unlock by the remote or push button. Also it doesn’t always lock when put into drive like the rest of the doors do.

The rear window defogger is smoking and sizzling. The connection on the passenger side glass that connects the moveable harness for the center glass smokes and sizzles when the rear defogger is on. There is a recall on these vehicles in Canada for this issue. My concern is that it may start a fire. The connector is right behind the right rear passenger seat, imposing a threat to the occupant of that seat. Also, the rear defogger comes on automatically with heated mirrors when remote started. I cannot use remote start, mirror defogger, or rear glass defogger currently due to this defect. I noticed a sizzling sound while driving the truck. I pulled over and began searching. I found smoke being emitted from the connector attached to the rear glass on the passenger side. This is a serious issue. It is a fire hazard. The vehicle could catch fire while driving or while remote engine start has been activated in temperatures lower than 40 degrees. There is a difference in an uncommon electrical short and a known problem. General Motors is aware of this issue and there has not be a notification to owners in the United States nor are there any recalls or suggested repairs. The safety of consumers is in jeopardy with this known problem occurring in multiple lines of their vehicles. Any with a power sliding glass could be affected.

DURING NORMAL OPERATION, WHEN PLACING THE VEHICLE IN REVERSE, THE INFOTAINMENT SCREEN INTERMITTENTLY TURNS BLUE, FLASHES, SCROLLS, OR TURNS BLACK. OFTEN TIMES A MESSAGE IS DISPLAYED THAT READS "SERVICE REAR CAMERA". ALSO, WHEN DRIVING THE INFOTAINMENT SYSTEM WILL TURN OFF, REBOOT, OR TURN BLACK INTERMITTENTLY.

2019 GMC SIERRA. CONSUMER WRITES IN REGARDS TO ISSUES WITH THE INFOTAINMENT SYSTEM. *LD THE CONSUMER STATED INFOTAINMENT SCREEN INDEPENDENTLY CHANGES TO DIFFERENT MODES. WHILE USING THE CAMERAS, THE INFOTAINMENT SCREEN INDEPENDENTLY SWITCHES VIEWS. THE TOUCH SCREEN WAS FAULTY. WHILE DRIVING, THE CAMERA WOULD INDEPENDENTLY ACTIVATE. THE DEALER AND MANUFACTURER WERE MADE AWARE OF THE FAILURE BUT, COULD DETERMINE A FIX. THE PHONE FEATURE RANDOMLY MAKES CALLS TO STORED NUMBERS. THE VOLUME WOULD INDEPENDENTLY REACH MAXIMUM VOLUME. THE CONSUMER WAS UNABLE TO TURN THE VOLUME DOWN MANUALLY. *JS

CRUISE CONTROL WOULD NOT DISENGAGE WHEN THE BRAKE WAS APPLIED I WAS ON A HIGHWAY TRAVELING 65 MPH. HAD TO TAKE AN EXIT RAMP TO AVOID A COLLISION WITH VEHICLE IN FRONT OF AND BESIDE ME.

EXCESSIVE BRIGHTNESS AT NIGHT ON BACK UP CAMERA WHEN PUTTING TRUCK IN REVERSE. GLARE IS SO BRIGHT, I CAN'T SEE ANYTHING IN CAMERA OR MY OUTSIDE REAR VIEW MIRRORS. I HAVE ACTUALLY GOTTEN OUT OF MY TRUCK TO MAKE I AM NOT GOING TO BACK INTO SOMETHING OR SOMEONE. WHEN IT IS RAINING AT NIGHT...FORGET IT, YOU JUST GUESS WHAT IS BACK THERE AND HOPE FOR THE BEST. I HANG A TOWEL OVER IT NOW WHEN I BACK UP AT NIGHT, IT IS A $60,000.00 TRUCK...WOW.

JUST BOUGHT THIS VEHICLE AND TOOK IT TO THE DEALER AND THEY DON`T HAVE AN EXPLANATION BUT THE BACKUP CAMERA MALFUNCTIONS. THIS COULD BE VERY DANGEROUS WITH YOUNG KIDS AND WHEN BACKING UP WHILE PICKING THE KIDS UP FROM SCHOOL AND AT LOCAL GROCERY OR DEPARTMENT STORES.

WHEN THE TEMPERATURE DROPS BELOW ABOUT 20 DEGREES (FAHRENHEIT) THE CENTER INSTRUMENT CLUSTER STARTS DISPLAYING EMERGENCY CODES THAT REQUIRE CONSTANT CLEARING, ONLY TO HAVE THE ERROR CODES REAPPEAR. THE SAME THING HAPPENS ON THE INFOTAINMENT HEAD UNIT IN THE CENTER STACK -- IT FLASHES, RESETS, CUTS THE SOUND IN AND OUT AND DISPLAYS TRAILERING CHECKLISTS. ALL OF THIS IS IMMENSELY DISTRACTING TO THE DRIVER AND CREATES A SAFETY HAZARD. I'VE HAD IT SERVICED AND HAVE BEEN TOLD GM ENGINEERS ARE AWARE OF THE ISSUE (ITS COMMON ON 2019 SIERRA AND SILVERADO 1500 TRUCKS) BUT HAVE BEEN UNABLE TO FIND A SOLUTION. I HAVE VIDEO OF BOTH TYPES OF ERRORS.

TRAILER DISCONNECT WARNING WHEN NO TRAILER IS CONNECTED COLD WEATHER SEEMS TO CAUSE THE ERROR THE WARNING CONTINUALLY POPS UP
