Acceleration & Cruise Control complaints by model year
1) Both screens (driver display and infotainment) go black intermittently. Sometimes the infotainment comes back on, however, you cannot use all the buttons. The hard buttons under the screen for climate control (aside from the on/off ) wont work. The climate will automatically go to 76 degrees on Max Defrost. The rear climate will shut off when this happens. It also causes the radio controls on the back of the steering wheel to not work. 2) It is extremely dangerous to not have a visual indicator for the speed at which I am driving. It is also dangerous to be driving with no AC and instead 76 max defrost, in triple digit temperatures. Especially with small children and a newborn baby. 3) The car has had several repair attempts by a Chevrolet Service department. 4) When it happens its sudden. No warnings. After it happens the Check Engine Light comes on sometimes. This started a week after the car was purchased in March 2026. It is still occurring now in August 2026.
NHTSA complaint #11758024 — an unverified report by a vehicle owner.
Engine failed going 70mph on highway at 2k miles. Display said acceleration no longer available and app said transmission code was needing to be checked however once taking to dealer I was told it was an oil sensor then told there was shredded metal in my engine and I needed a full engine replacement. My car was in the dealership for over 50 days. I was pregnant and with two small children in the car when engine failed at high speeds. After my car was returned to me the engine overheated and failed again. The dealer claimed GM sent them an engine with cut hoses. I was 9 months pregnant when this occurred also on the highway going 65mph. GM refused to buy back the vehicle 3 times.
NHTSA complaint #11710726 — an unverified report by a vehicle owner.
7/13/25: Car repeatedly jerking/shuddering/rough ride. A flashing check engine light came on for 10 or 15 minutes. After stopping car and restarting it, the check engine light went off. 9/15/25: Car jerking and another flashing check engine light. Took to dealership. They drove it and said no codes stored. Told it was probably the transmission "breaking in." Took home. Car continued to jerk/stumble. 8/28/25 to 9/15/25: Car jerking and flashing check engine light back on. Took to Autozone. A Random/Multiple Cylinder Misfire Code was detected (P0300). Took to dealership and confirmed P0300 Code stored. GM TAC engineers involved. Told they were unable to figure out why car was having multiple misfires. Returned car to me because no active code/light. 9/29/25: Car jerking and flashing check engine light back on. Got a warning of "reduced acceleration and drive with care." Car lost power. I have video of this and contacted On Star with report generated and P0300 code. On 10/1/25 on way to dealer, car making audible ticking noise. I have video of this. Took to dealer, the ECM was replaced and oil changed because it was "very dark" (in vehicle with 4,600 miles). Car continued to jerk/stumble. Told by dealer that problem would have to get worse before diagnosis could be made. 10/31/25: Jerking and another flashing check engine light with "reduced acceleration drive with care warning." Turned car off and engine light off. On Star report P0300. Took to dealer. The dealership was given the videos of check engine lights/reduced acceleration warnings and ticking noise video. All show problem happening around 1,200 rpms. Told by dealer on 11/11/25 that GM rep said they will not pay dealer for any work because no active engine light/codes. Told to pick up car. Asked dealer today for reason in writing, but no response. Very concerned about vehicle safety when repeatedly going into limp mode and flashing check engine lights with GM offering no solution.
NHTSA complaint #11698805 — an unverified report by a vehicle owner.
While driving our 2023 Chevrolet Duramax diesel suburban, I was waiting, at a complete stop, against the median to make a U turn. When the traffic cleared, I began the turn when I suddenly noticed a nearly complete loss of power, hesitancy of engine engagement, and little response to the gas pedal being depressed. Then an error message appeared on the dashboard stating "Low acceleration warning". There was very little acceleration power available. The rear wheels seemed to spin. I was perilously endangered while making a U-turn across lanes because of this loss of power. The vehicle was then taken immediately to our local Chevrolet dealer who diagnosed a error code message (P0700, 0747) related to transmission valve and injectors. We are very concerned that this was a dangerous occurrence and should be further investigated. We have a 30-year history of Suburban ownership, however this is our first diesel model. We have never had problems of this significance, or seen this error message before. Since this diesel Suburban is nearly new, we are particularly concerned about the durability and safety of this vehicle. Please see attached servive report. The AC compressor was also failed and replaced
NHTSA complaint #11633963 — an unverified report by a vehicle owner.
WHILE VEHICLE IS IN FOWARD DRIVING MOTION ON STREET OR HIGHWAY(20 - 70MPH)OUT OF NO WHERE, TRUCK WILL HAVE A QUICK SECOND HALT IN ITS MOTION, AS IF SOMEONE PULLED AND RELEASED THE EMERGENCY BRAKE(SEE ATTACH RECORDING) ALL I FEEL IS A SUDDEN JERK WHICH ITS INTENSITY DEPENDS ON TRAVELING SPEED. IT STARTLES ME EVERY TIME! DURING THIS TIME, THE SPEED GAUGE DROP THEN RESUMES REGULAR SPEED, CHECK ENGINE LIGHT APPEAR BUT IMMEDIATELY TURNS OFF AS DOES THE WORDS "PARK ASSIST OFF" ALSO DISPLAYS THEN IMMEDIATELY GOES AWAY. THESE SPORADIC EPISODE ARE BECOMING MORE FREQUENT AND COULD CAUSE TRAGIC ACCIDENT. I HAVE MADE SEVERAL ATTEMPTS TO HAVE ISSUE DIGNOSED BUT UNFORTUNATELY DOES NOT GENERATE CODES, ACCORDING TO ONSTAR. DEALERSHIP WAS UNABLE TO DUPLICATE THE ISSUE. HOWEVER THEY RECOMMENDED REPLACING THROTTLE POSITION SENSOR, BRAKE LAMP SWITCH, SPARK PLUGS AND WIRES, MASTER CYL AND BRAKE BOOSTER, FLUSHING AND REPLACING BRAKE FLUID FOR POSSIBLE SOLUTIONS BUT IT DID NOT FIX THE PROBLEM. WHAT I HAVE NOTICE THE ISSUE BECOMES MORE FREQUENT WHEN THERE IS STUDDEN BRAKING(STOP AND GO TRAFFIC) FOLLOWED BY INCREASED ACCELERATION. IN ADDITION WHILE SITTING IDLE IN PARK FOR ABOUT 10MINS WITH A/C ON, TRUCK IDLES DOWN LIKE IT IS ABOUT TO CUT OFF(ENGINE LIGHT COMES ON THEN IMMEDIATELY OFF) BUT DOESN'T . DEALERSHIP WAS UNABLE TO DUPLICATE THAT TOO. ALSO AFTER BRAKING FOR STOP LIGHT I SOMETIMES FEEL SEVERAL THUMPS AS THOUGH I'M NOT PUTTING ENOUGH PRESSURE ON BRAKE PEDDLE. NO MATTER HOW MUCH PRESSURE I PUT ON BRAKES THE THUMPS STILL SPORADICALLY OCCUR. SOMETIME WHEN THIS HAPPENS IT IS FOLLOWED BY THE FIRST ISSUE I MEANTIONED WHEN DRIVING IS RESUMED (HAULT,ENGINE LIGHT, PARK ASSIST OFF WARNING).
NHTSA complaint #11015866 — an unverified report by a vehicle owner.
ON MOTHER'S DAY I WAS DRIVING MY 2010 CHEVY SUBURBAN WITH 92K MILES ON IT. WHEN I WAS LEAVING THE CAR WASH I ACCELERATED ON THE GAS TO GET ONTO HWY 29. AS SOON AS I GOT UNTO HWY 29 A CAR SWITCHED FROM THE LEFT LANE TO CROSS OVER IN FRONT OF MY VEHICLE TO GET ON TO THE ON RAMP FOR HWY 37 EAST. I PRESSED THE BRAKE TO ENSURE I WOULDN'T HIT HIM. HOWEVER, WHEN I PRESSED THE BRAKE THE SUV WAS STILL ACCELERATING. SO I LOOKED DOWN TO SEE IF THE GAS PEDDLE WAS STUCK UNDER THE MAT. IT WASN'T. SO PRESSED THE BRAKE HARDER. THE SUV WAS STILL ACCELERATING. I THEN PUT THE SUV IN NEUTRAL, BUT IS WAS STILL ACCELERATING ALL THE WHILE KEEPING MY FOOT FIRMLY PRESSED ON THE BRAKE. SO I MOVED THE GEAR SHIFT INTO THE MANUAL POSITION. ONCE MOVED INTO THE MANUAL POSITION THE DASH READ M2 WHICH REPRESENTS SECOND GEAR. SO I QUICKLY TOOK MY FOOT OFF THE BRAKE, GAVE IT GAS, QUICKLY SHIFTED BACK INTO NEUTRAL WHILE HITTING THE BRAKE AND THEN INTO DRIVE. THE ENGINE REVVED REAL LOUD AND THEN THE BRAKE STARTING WORKING AGAIN AND ACCELERATOR WAS NORMAL. MY VEHICLE WAS TOWED TO TEAM CHEVROLET IN VALLEJO & A CASE WAS OPENED WITH GM. I HAVE BEEN GETTING THE RUN AROUND WITH BOTH AND MOSTLY RECENTLY WAS TOLD A LIE FROM THE GM REPRESENTATIVE.

VEHICLE GAS GAUGE AND ODOMETER GAUGES CLUSTERS ARE NOT WORKING THIS PUTS US IN DANGER I DID NOT KNOW HOW MUCH GAS I NEED AND HOW FAST I WAS GOING THIS SHOULD BE FIXED BY THE MANUFACTURER BECAUSE IT WAS A CLUSTER DEFECT
NHTSA complaint #10993648 — an unverified report by a vehicle owner.
THE GM INSTRUMENT CLUSTER STEPPER MOTORS AND LIGHTS HAVE FAILED. THIS RESULTS IN A SAFETY HAZARD BECAUSE IT IS IMPORTANT TO KNOW THE SPEED OF THE VEHICLE AND THE FUEL LEVEL AS WELL AS OTHER IMPORTANT ENGINE INFORMATION.
NHTSA complaint #10850358 — an unverified report by a vehicle owner.
WHILE DRIVING, VEHICLE SUDDENLY GOES INTO "REDUCED ENGINE POWER" MODE ("LIMP MODE") WITH CONSOLE MESSAGE "TRACTION CONTOL DISABLED, SERVICE STABILITRAK, ENGINE POWER REDUCED". GENERALLY OCCURS WHEN TEMPERATURES ARE LOWER THAN 25 DEGREES FARENHEIT. SHUTTING DOWN VEHICLE FOR SEVERAL MINUTES AND RESTARTING LEADS TO NORMAL OPERATION, HOWEVER VEHICLE WILL GENERALLY REPEAT SAME PROBLEM WITHIN 5-15 MINUTES IF OUTSIDE TEMPERATURE IS COLD ENOUGH (BELOW 25 DEGREES FARENHEIT) . ERROR CODE P1235 (THROTTLE POSITION SENSOR 1-2 CORRELATION...) IS SET, BUT MAY NOT PERSIST IN MEMORY. GM IS PROVIDING OWNERS WITH ADDITIONAL PROTECTIONS FOR 10 YEARS/120,000 MILES UNDER CSC-10047220-3332 (BULLETIN NO. 11273), HOWEVER NOT ALL VINS ARE INCLUDED. VEHICLE HAD THROTTLE BODY (INCLUDING SENSOR) REPLACED IN 2010 AND APPEARS TO BE EXHIBITING EXACT PROBLEMS COVERED BY THIS BULLETIN, HOWEVER GM DEALER AND GM ARE NOT EXTENDING PROTECTION FOR THIS VEHICLE. DEALER IS RECOMMENDING ANOTHER NEW THROTTLE POSITION SENSOR AND/OR THROTTLE BODY (INCLUDING SENSOR), ALONG WITH COMPUTER RESET. THIS INTERMITTENT PROBLEM HAS OCCURRED FOR MORE THAN THREE YEARS AND POSES A SIGNIFICANT SAFETY RISK WHEN THE VEHICLE IS IN MOTION AT NORMAL HIGHWAY SPEEDS (DRASTIC SUDDEN DECELERATION IN TRAFFIC).

THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC. A POLICE REPORT WAS NOT FILED. THE CONTACT SUSTAINED INJURIES THAT DID NOT REQUIRE MEDICAL ATTENTION. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS DESTROYED. THE APPROXIMATE FAILURE MILEAGE WAS 129,000.
NHTSA complaint #10781063 — an unverified report by a vehicle owner.
MY '03 CHEVROLET SUBURBAN HAS DEVELOPED WHAT APPEARS TO BE A VERY COMMON CONDITION WHERE THE ENTIRE INSTRUMENT CLUSTER BECOMES INOPERABLE. FOR EXAMPLE, WHILE TRAVELING AT LOW, IN TOWN SPEEDS, THE SPEEDOMETER WILL HAVE READINGS IN THE 60S, 70S' AND 80S. WHILE IN THE PARK POSITION, THE SPEEDOMETER WILL READ 55MPH. THIS IS ABSOLUTELY A SAFETY ISSUE AND I AM REALLY SHOCKED THAT THE NHTSA HASN'T FORCED A RECALL. THERE ARE LITERALLY THOUSANDS OF REPORTS ONLINE OF THIS EXACT PROBLEM. GENERAL MOTORS IS AWARE THAT THIS IS A WIDE SPREAD PROBLEM, AS THEY EVEN EXTENDED. GENERAL MOTORS EVEN PROVIDED OWNERS WITH A SPECIAL COVERAGE THAT EXTENDS THE WARRANTY ON THE INSTRUMENT PANEL CLUSTER FOR THE CONDITION DESCRIBED ABOVE, AS LONG AS THE VEHICLES AGE AND MILEAGE FALLS WITHIN CERTAIN PARAMETERS. THOSE PARAMETERS ARE THE MAIN REASON FOR MY COMPLAINT. THOSE PARAMETERS ARE 1) 7 YEARS OF THE IN SERVICE DATE, AND 2) 70,000 MILES, WHICH EVER OCCURS FIRST. MY CLAIM TO HAVE THE INSTRUMENT CLUSTER IN MY VEHICLE REPAIRED UNDER THE SPECIAL COVERAGE WAS DENIED ON 9/4/09 BECAUSE THE MILEAGE OF MY VEHICLE WAS 93,000 MILES AT THE TIME OF MY REQUEST. I BELIEVE THAT THIS IS A LARGE SCALE SAFETY PROBLEM THAT WARRANTS A RECALL BY GENERAL MOTORS RATHER THAN AN EXTENSION OF WARRANTY WITH UNREASONABLE MILEAGE PARAMETERS. EXTENDING THE WARRANTY ALONE IS A CLEAR ADMISSION OF A KNOWN WIDESPREAD ISSUE. IS NHTSA IN BED WITH GM TOO? I GUESS I SHOULDN'T BE SURPRISED.
NHTSA complaint #10702698 — an unverified report by a vehicle owner.
THE SPEEDOMETER NEEDLE BEGAN "CATCHING," NOT MOVING SMOOTHLY. AFTER ABOUT 2 WEEKS IT WOULD NOT RESET TO 0 WHEN STOPPED THEN AFTER 1 MORE DAY IT QUIT REGISTERING COMPLETELY.
NHTSA complaint #10690807 — an unverified report by a vehicle owner.
TRAVELING ON HWY 35 IN DALLAS TEXAS AND MESSAGE APPEARED ON INSTRUMENT CLUSTER "REDUCED POWER MODE". VEHICLE SPEED DROPPED TO 20 MPH (POSTED SPEED WAS 70 MPH). HAD TO HAVE VEHICLE TOWED TO DEALERSHIP AND A FIX HAS NOT BEEN DETERMINED. THE DEALER SO FAR HAS CHARGED ME $900 AND IT DID NOT FIX IT.THIS SAME PROBLEMS BEEN POSTED ON GM FORUMS, GM TRUCK FORUMS WITH THESE SAME RESULTS. THERE ARE HUNDREDS OR MAYBE THOUSANDS OF COMPLAINTS FOR THIS ISSUE. IT IS VERY UNSAFE.
NHTSA complaint #10669788 — an unverified report by a vehicle owner.
BOUGHT THIS VEHICLE A FEW DAYS BEFORE THE FIRST INCIDENT. I DROVE IT HOME FROM OVER TWO HOURS AWAY, DROVE IT ALL AROUND THE DAY BEFORE, NO PROBLEMS. THEN I WAS DRIVING DOWN A BYPASS AT ABOUT 60 MILES AN HOUR AND THE ENGINE SHUT OFF! I HAD NO POWER STEERING, NOTHING! I WAS ABLE TO PULL OVER, SHUT IT OFF AND ONCE I TURNED IT BACK OVER IT WAS JUST FINE. SO I CAUTIOUSLY STARTED DRIVING, IT HAPPENED AGAIN A FEW MILES DOWN THE ROAD ONLY THIS TIME IT STALLED THEN REGAINED POWER AND QUICKLY SHUT OFF AGAIN. ONCE ENGINE WAS TURNED OFF AND RESTARTED, IT WAS FINE, IT DID THIS TO ME 5 TIMES WITHIN 5 MILES. I ALMOST GOT HIT TWO OF THOSE TIMES BY OTHER VEHICLES, ONCE WHEN I WAS TURNING ONTO A ROAD. I AM GLAD MY KIDS WERE NOT IN IT. I AM SCARED TO DRIVE ON TWO LANE ROADS WITHOUT ROOM TO PULL OVER.

NHTSA complaint #10610416 — an unverified report by a vehicle owner.
THE SPEEDOMETER IS COMPLETELY GONE ALONG WITH SEVERAL GAUGES SUCH AS THE OIL, GAS, AND RPM METERS. I AM UNABLE TO TELL HOW MUCH GAS I HAVE OR HOW FAST I AM GOING. THIS HAS HAPPENED A LOT TO THESE VEHICLES OVER THE PAST 10 YEARS. GM OFFERED A REPAIR BUT ONLY FOR VEHICLES WHO WERE NOT OVER A CERTAIN MILEAGE. THIS IS A SAFETY ISSUE AND NEEDS TO BE REPAIRED IN ALL VEHICLES. ADDITIONAL, THE ELECTRICAL SYSTEM IS OUT OF WHACK. MY HEATED SEATS TURN ALL THE WAY UP TO HIGH WITHOUT ME PRESSING ANYTHING. MY TV SYSTEM IS NOT WORKING. EVERYTHING SEEMS TO BE FALLING APART.
NHTSA complaint #10582808 — an unverified report by a vehicle owner.
WHEN TRYING TO COME TO A STOP THE VEHICLE SEEMS TO SUDDENLY ACCELERATE RIGHT BEFORE STOPPING. THE VEHICLE IS GOING LESS THAN 5 MPH AND IT QUICKLY LUNGES FORWARD RIGHT BEFORE IT GETS COMPLETELY STOPPED. HAS DONE THIS ON AT LEAST 3 DIFFERENT OCCASIONS. IF I HAD BEEN VERY CLOSE TO THE CAR/OBJECT IN FRONT OF ME I MIGHT HAVE HIT IT.
NHTSA complaint #10481282 — an unverified report by a vehicle owner.
AT RANDOM YOU WILL JUST BE DRIVING DOWN THE ROAD AND A MESSAGE COMES ON THAT SAYS REDUCE ENGINE POWER AND THE T/C LIGHT COMES ON ALONG WITH THE CHECK ENGINE LIGHT. THIS HAS HAPPENED SEVERAL TIMES, IS VERY UNSAFE, AND IS GETTING WORSE. WE HAVE HAD WORK DONE TO TRY AND FIX THE PROBLEM BUT ITS STILL HAPPENING. WE DON'T HAVE TONS OF MONEY TO FIX THIS, LIVE IN THE COUNTRY, AND HAVE 5 KIDS. THIS IS OUR ONLY TRANSPORTATION AND WE HAVE A RATHER LARGE LOAN ON THE THING AND ITS TURNING INTO YARD ART.
