My 2018 Chevy Silverado 1500 keeps stalling/dying when making turns. There is zero correlation to speed, stop and go, slow, fast, sharp or gradual turn, acceleration or slow rolling start, hard stop then start. It happens mostly when turning right, or left, mostly right. It 's happened 12 times from July '22 to January '23.Dash only shows mileage when it dies. (digital). Rest of console is black (similar to when remote started). It has happened when remote started (twice), other times when manually started with the key. I have tried to recreate stalling turning/starting fast/slow/sharp, etc in empty parking lots while videoing multiple times without success. I took it in to dealer's service center in January '23. They trouble shot it, determining that it was a faulty fuse box and changed that out. It has continued to occur despite this "fix." It has occurred 8 times since January, four of...

Took to the dealership and they did a diagnostics and are requiring me to purchase a new transmission valve. The truck only has 84,000 miles and they have to Remove and replace transmission, Transmission has burn smell, color of fluid is dark, excessive metal shavings present the problem I presented to the dealership was that after you exceed the speed of 50 miles an hour the truck starts to jerk and pulls on you and there’s a very screeching sound every time you accelerate and it always jerks hard on the highway and it feels like if I’m being hit by something from the back

Yes, our safety as well as others are put at risk this can cause an accident to happen on the road while driving, most likely to get rear ended. Today it gave me a scare because my 2 year old granddaughter was in the truck.

My engine cooling lines are leaking and that can potentially cause a very bad problem to my engine itself imagine I'm driving and they pop off causing me to lose all my oil and then my engine can drown and sudden stop while I'm on the highway I was first aware of the problem when my veichle had to be taken in because the transmission was failing at around 55000 miles the dealership told me about this problem which said did not need to be addressed since it's a small leak on the lines but once I got down under my truck and took of the undercover it's more than a small leak now I'm facing having to spend money on a veichle that should not be giving me problems yet at the miles it's at I'm trying to get a hold of my extended warranty to see if it's...

Sudden loss of vehicle electrical power as well as steering and break control due to faulty negative battery terminal. Engine will stall and steering wheel will kick back and issue a stabilitrak service message. Vehicle will become inoperable while still moving with no way to control.

During the mornings when first starting my truck, I get a stutter or hesitation to the engine when accelerating out of my driveway. This happens just about every morning. I have determined that the truck has to be off for about 10+ hours. The stutter/hesitation goes away after the car warms up in about 1 mile. Have had the truck into the shop but they can find NO problems.

Our 2018 Chevrolet Silverado 1500 was purchased new and only serviced at Chevrolet dealerships. While on vacation we were driving on a 3-lane paved road and then engine started knocking for a few seconds and then a chime could be heard and the check engine light came on. The vehicle lost power and the vehicle was difficult to control. We were fortunate that other vehicles were able to avoid us since our truck slowed quickly (without the brakes being applied). The vehicle had to be towed to a local Chevrolet dealer for diagnostics. The dealer found that the hydraulic lifters on the right bank of the engine collapsed (resulting in a misfire) and there was extensive engine damage. The vehicle was equipped with a 5.3l engine with AFM/DFM (cylinder deactivation). Mileage was 64,562. Vehicle was repaired with "upgraded" valve train parts from General Motors as this failure mode seems to...

I have a 2018 Chevy Silverado 1500 that I bought in June of 2018, brand new from integrity Chevy in Chattanooga tn.. One ago ago I was driving home and the check engine light came in and starting running poorly and you could hear a knocking noise coming from the engine. I took it back to integrity Chevrolet in Chattanooga, the employee at the auto service counter got inside and started the truck and he new at once what the issue was, he didn’t even take it back to the shop so the mechanic could look at it. He told me it was the lifters knocking. I left the truck with them. The next day he called me and told that the lifters where bad and had bent push rods. They had to replace everything on both sides, told me how much it would cost. It was out of warranty...

10 degrees outside starter motor will freeze up and not want to start the truck. had 3 mechanics not a deal all look at it, tested the battery and came to the starter motor is defective. to have the starter replaced at the dealer for its under warranty.

Vehicle will not start, starter is bad

Driving on highway 70 mph with out prior warning the truck begins to shake, backfire, lunging, loss of power, all the lights on the dash starting going crazy, cars behind me trying to avoid hitting me ,it wouldn't speed up, having a hard time getting it off the road and out of the way of highway traffic before getting rear ended by traffic behind me. The truck only has a little over 60000 miles on it which is just beyond the 60000 mile warranty, The truck lost compression because of a lifter failure in the motor. After this I have no interest in ever buying another Chevy product, If they cant build a motor that will last more than 3 years maybe they should rethink their future in the auto industry.

radiator crack. and also looks like previous years have the exact problem and have a special coverage done on them, Special Coverage Adjustment 15829 Radiator Leak #PI1513A Bulletin No.: PI1513F

Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up? How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups?

The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts. The exhaust adaptive valve started making a terrible noise at 40k miles. I took it to the dealership for them to tell me my extended warranty doesn't cover it and to buy an aftermarket exhaust because it would be too expensive to replace it. I think they quoted me at $1200

On Saturday the check engine light came on then Sunday it flashed service restraint system soon dash lights came on clicked and lights stayed on about a memory then went off truck wouldn’t start on Sunday night no lights on dash worked

I HAVE A 2018 THAT IS BARELY 2 YEARS OLD, AND A LEAKING RADIATOR! GM IS DOING NOTHING TO OWN UP TO THIS ISSUE, AND THEY ARE EXPECTING ME TO PAY THE ENTIRETY FOR A REPLACEMENT, AND I DON'T EVEN HAVE CONFIDENCE IT WON'T HAPPEN AGAIN. THIS BULLETIN SHOULD BE EXTENDED TO COVER ALL YEARS UNTIL GM PROVES THEY HAVE A SOLUTION IN PLACE. IT IS COMPLETELY UNETHICAL FOR GM TO NOT ADDRESS THIS ISSUE AND EXPECT ME TO PUT THIS MUCH MONEY INTO A BRAND NEW TRUCK. I SLOWLY BEGAN TO NOTICE THE COOLANT RESERVOIR GOING DOWN. I EVENTUALLY BROUGHT IT TO MY DEALERSHIP (TWICE), AND ON THE SECOND VISIT THEY FOUND THE LEAK, ALTHOUGH MILEAGE WAS OVER THE BUMPER TO BUMPER WARRANTY DURING THE SECOND...

NEW VEHICLES ARE NOW DESIGNED TO BREAK ON YOU EASILY SO US CUSTOMERS SPEND MORE ON PARTS AND LABOR.

TRANSMISSION OVERHEATS WHEN BACKING A TRAILER UP A SLIGHT HILL AND WILL NOT MOVE UNTILE IT COOLS DOWN.

I STARTED MY VEHICLE AND PUT THE TRUCK IN REVERSE TO BACK OUT OF A PARKING SPOT. GAVE THE TRUCK GAS AND IT WOULDN'T ACCELERATE. PUT THE TRUCK BACK IN PARK AND LOOKED AT THE GUAGES AND THERE WERE NO RPM'S SHOWING ON THE CLUSTER AND THE OIL PRESSURE WAS AT ZERO. THERE WAS A MESSAGE THAT SAID TRAILER BRAKE SYSTEM ON THE SCREEN. I TURNED THE TRUCK OFF AND ON AGAIN AND THE SAME THING HAPPENED. I PUT THE TRUCK IN DRIVE AND IT WOULD MOVE FORWARD BUT THE MOTOR RAN VERY ROUGH AND THERE WAS NO POWER STEERING. I DISMISSED THE FIRST MESSAGE AND ANOTHER MESSAGE POPPED UP THAT SAID "STEERING ASSIST IS REDUCED, DRIVE WITH CARE." I PULLED INTO ANOTHER PARKING SPOT, TURNED THE TRUCK OFF, AND WAITED FOR A RIDE. I STARTED THE TRUCK WHEN MY RIDE SHOWED UP TO MAKE SURE IT WAS STILL NOT...

TRUCK WILL LOSE ALL POWER, EVERYTHING WILL SHUT OFF, AND THEN COME RIGHT BACK ON. IT HAS HAPPENED WHILE ACCELERATING INTO TRAFFIC, SLOWING DOWN TURNING RIGHT AND TURNING LEFT, AND WHILE MOVING STRAIGHT AHEAD. IT HAS BEEN IN THE SHOP ONCE FOR THIS SAME ISSUE AND THEY TELL ME THEY CANNOT FIND ANYTHING WRONG WITH IT. THE STABILITRAC WARNING WILL COME ON AND GO OFF AND HAVE HAD STALL WARNING FLASH IN TRAFFIC AT STOP LIGHTS. THIS HAS BEEN GOING ON FOR THE LAST 12,000 MILES AND I HAVE 20,083 MILES ON TRUCK NOW. THE CLOCK AND RADIO RESET. IT SHUTDOWN PULLING INTO TRAFFIC ON A BUSY HIGHWAY AND WAS A VERY DANGEROUS SITUATION. BEEN TRYING TO GET IT INTO DEALERSHIP SINCE 3 WEEKS AGO AND NO LUCK.

HAD THE TRAMISSION FLUID CHANGED TWO DAYS LATER. DEALER JUST STATED THEIR WAS A LOSS OF COMMUNICATION WITH THE ENGINE. ONE WEEK LATER RECEIVED TRANSMISSION HOT, IDLE ENGINE MESSAGE ON THE INTERSTATE WHILE HAULING THE SAME TRAILER WITH ONLY A RIDING LAWNMOWER.

HIGHWAY SPEED WAS 70 MPH UNTIL IT OVERHEATED, THEN DROVE 50-55 MPH TO GET TO MY DESTINATION TRYING NOT TO LET TRANSMISSION TEMPERATURE OVER 220.

THE PLASTIC RADIATOR HAS CRACKED AND IS LEAKING COOLANT HEAVILY. TRUCK STILL UNDER POWERTRAIN WARRANTY BY GM IS ONLY OFFERING TO COVER 20% OF THE $1,823 REPAIR COST. I NOTICED IT WHEN STOPPED TO GET GAS, THE VEHICLE LEAKING APPROXIMATELY 1.5 GALLONS OF COOLANT WHILE STOPPED FOR APPROXIMATELY 3 MINUTES. THIS CAUSED THE VEHICLE TO OVERHEAT AND NEEDED TO ADD COOLANT JUST TO DRIVE TO SHOP. *TR

TRANSMISSION SHIFTS HARD FROM FIRST TO SECOND/SECOND BACK TO FIRST. I NOTICED THIS ABOUT A WEEK AFTER PURCHASING TRUCK. SHIFTS HARD MOSTLY IN 2WD, NOT SO MUCH IN 4WD OR HAULING/TOWING. LEAF SPRINGS AND SHACKLES HAVE SQUEAKED SINCE DAY ONE OF PURCHASE. ENGINE OIL PRESSURE IS AT 12-15PSI AT IDLE AND WILL NOT EXCEED 32-35 PSI UNDER NORMAL CONDITIONS WITH OR WITHOUT A LOAD. I'VE CHANGED THE OIL FILTER AND OIL PRESSURE SENSOR MULTIPLE TIMES. THERE ALSO SEEMS TO BE A CHIRP/TICK COMING FROM THE PASSENGER SIDE OF THE ENGINE COMPARTMENT. I'VE BEEN TRYING TO NARROW IT DOWN FOR THE LAST FEW WEEKS. SEEMS TO BE SOMETHING GOING ON IN THE ENGINE ITSELF OR POSSIBLE THE AC COMPRESSOR. TRUCK HAS 42,450 MILES

STARTER IS BAD, DRAGS WHEN COLD OR ITS DRAWN THE BATTERY DOWN TO WHERE IT WON'T START. JUMPED IT ONCE, THE DEALERSHIP REPLACED THE BATTERY BUT THAT 650 COLD CRANKING AMP IS NOT BIG ENOUGH FOR THE STARTER. WE NEED TO GO TO A 1000 COLD CRANKING AMP PLUS A 200 AMP ALTERNATOR.
