When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

AIR BAGS
I have received a Code 95 error message for my 2018 Chevrolet Spark, which per the GM owner's manual means that there is an air bag problem. But, the alert does not appear consistently when operated. When driving, it does not appear. The problem has not been reproduced or confirmed by a dealer or independent service center. The code only comes on after the car has been idling and not being driven (for example, it takes 2-3 minutes while in park but the engine being on for the code to come up on the screen). If the car is put into drive a minute or less after turning the ignition, the code does NOT appear; it only does when parked and the engine is running after a few minutes. The car is available for inspection upon NHTSA/DOT request. My safety is put at risk if the air bag does not deploy; if the alert code does not consistently appear when the car is in operation, it puts my safety at risk because I would not have any indication that there is a possible problem. The car has not been inspected by the manufacturer (to my knowledge), police, insurance representatives, or others. This has occurred at least three times since the start of 2026, with the most recent occurrence in June 2026.

The contact's husband owns a 2018 Chevrolet Spark. The contact stated that the brake booster failed while driving at various speeds on several occasions.

SERVICE BRAKES
This is the third time while driving that my brakes have simply just gone out. It’s usually on the freeway while at high speeds and I’m nearly not able to stop. This is the third time in three years. No lights come on on the dashboard and no warnings happened at all the brakes just simply stopped working. It takes extreme pressure to try to stop and I’m usually told that it’s some part of the vacuum.

MY CHEVROLET SPARK CANNOT DECIDE WHAT GEAR IT WANTS TO BE IN, CAUSING DELAYS THAT ARE DANGEROUS WHEN PULLING OUT IN TRAFFIC OR TURNING ACROSS LINES OF TRAFFIC. FOR INSTANCE, I SLOW DOWN TO GET INTO THE CENTER TURNING LANE OF A 5-LANE STREET AND THEN WHEN CLEAR, I ACCELERATE TO MAKE THE TURN. THE CAR FEELS LIKE IT MAKES A SHORT STALL AS IT CAN'T DECIDE IF IT NEEDS TO GET INTO A HIGHER OR LOWER GEAR. IT CLEARLY TAKES A LONG TIME AND GOES UP AND DOWN WHICH PLACES ME UNCOMFORTABLY TOO CLOSE TO ONCOMING TRAFFIC. OTHER TIMES WHEN I PULL OUT IN TRAFFIC, THE SAME SCENARIO REPEATS. I WONDER IF IT SHIFTS INTO A TOO HIGH A GEAR TOO SOON THEN DOWN SHIFTS ONE GEAR AND THEN UPSHIFTS AS THE CAR STARTS TO ACCELERATE. SEVERAL TIMES A DAY WHEN I SLOW TO ADJUST TO TRAFFIC CONDITIONS AND THEN ACCELERATE AFTER SLOWING, THE CAR LAG/STALL HAPPENS AS THE TRANSMISSION SHIFTS UP AND DOWN THROUGH THE GEARS. THE CAR JUST CAN'T DECIDE WHAT IS THE BEST GEAR TO BE IN. I FEEL THAT THIS IS DANGEROUS. IT CERTAINLY MAKES ONE VERY UNEASY WHEN YOU PULL OUT IN TRAFFIC AND THEN THE CAR BARELY MOVES FOR A VERY CRITICAL SECOND OR TWO.

SERVICE BRAKES
FROM TIME TO TIME WHEN BRAKING, A THUMPING SOUND IS HEARD IN THE REAR DRUM BRAKES OF MY BRAND NEW CHEVY SPARK. I CANNOT DECIDE WHICH ONE THE NOISE IS COMING FROM, OR BOTH. IT WILL GO AWAY AFTER A WHILE. IT OCCURS MORE FREQUENTLY WHEN I NEED TO BRAKE HARD, BUT NOT ALWAYS. AND IT DOES NOT HAPPEN EVERY DAY. THE CAR IS NEW. WHEN I TOOK IT TO THE DEALER FOR THE VERY FIRST OIL CHANGE, I ASKED THEM TO LOOK INTO IT. THEY KEPT THE CAR 3 DAYS. THEY SAID THEY DROVE IT BUT DID NOT NOTICE ANY NOISE. TO MY SURPRISE, DURING THOSE THREE DAYS, THE DEALERSHIP DID NOT PULL THE WHEEL AND LOOK INSIDE THE DRUM FOR A BROKEN SPRING, WARPING, DELAMINATION OR SOME OTHER COMPONENT DEFECT OR SYSTEM FAILURE. I'VE NEVER HAD A CAR WITH DRUM BRAKES MAKING THIS SOUND.

THIS IS A PERIODIC OCCURANCE WHEN GOING STARTING AT 0MPH AT ANY POINT DURING A TRIP. NORMALLY THE ENGINE WILL REV SMOOTHLY BUT THERE ARE TIMES WHEN GOING FROM A COMPLETE STOP TO GETTING TO AT LEAST 30MPH IT FEELS AS IF THE ENGINE IS JUST TAKING IN AIR AND IT JUST REVS UP AND THE CAR STARTS TO ROLL BUT DOESNT ACTUALLY ACCELLERATE PROPERLY AND THIS CAN RESULT IN AN ACCIDENT IF YOU HAVE TO MOVE SUDDENLY TO AVOID BEING HIT. I HAVE THE LT1 MODEL SPECIFICALLY.
