MY 2018 SUBURBAN REQUIRED OVER $400 WORTH OF EXPENSES TO REPLACE A VALVE AND RECHARGE THE FREON IN THE AC. LESS THAN A WEEK LATER IT REQUIRED A NEW CONDENSER AND ANOTHER $1250 IN REPAIR. THE CONDENSER WAS RECALLED IN 2015-2017 SUBURBANS AND IT SOUNDS TO ME LIKE IT SHOULD INCLUDE THE 2018 MODEL YEAR AS WELL. I SHOULD NOT HAVE TO PUT MORE THAN $1650 IN REPAIRS FOR THAT INTO A VEHICLE THAT IS LESS THAN THREE YEARS OLD. I HAVE A FAMILY OF SIX INCLUDING A NINE MONTH OLD AND IT IS NOT SAFE IN THE SUMMER HEAT TO BE DRIVING THEM AROUND AS THIS IS THE ONLY CAR WE HAVE THAT FITS THE ENTIRE FAMILY. MY WIFE IS A DOCTOR AND FREQUENTLY WORKING AT THE HOSPITAL DURING THIS PANDEMIC SO IT IS THE ONLY REMAINING VEHICLE I HAVE AND THE ONLY ONE THAT FITS THE REST OF THE FAMILY. *TR

I DRIVE A 2018 CHEVY SUBURBAN. THIS CAR HAD NO LIGHTS ON AND HAS LESS THAN 18K MILES ON IT. IT IS JUST OVER TWO YEARS OLD AND THERE ARE NO RECALLS ON THE VEHICLE. I WAS DRIVING WITH MY [XXX] CHILD AND WE HAD DRIVEN ABOUT A MILE. WE WERE ON THE FEEDER ROAD ABOUT TO GET ON THE FREEWAY. THE CAR STARTED SPONTANEOUSLY ACCELERATING ON ITS OWN. JERKING FASTER AND FASTER WITHOUT ME TOUCHING THE GAS. IT WAS LIKE WE WERE ON A RUNAWAY TRAIN. I PANICKED AND SLAMMED MY FOOT ON THE BREAKS. THERE WERE NO BREAKS - NO TENSION OR PRESSURE IN THE BRAKE PEDAL. THE PEDAL JUST CONTINUOUSLY SLAMMED INTO THE BOTTOM OF THE CAR. I COULDN'T STOP US. I THOUGHT QUICKLY AND SLAMMED MY FOOT ON THE PARKING BRAKE AS OUR CAR CONTINUED TO ACCELERATE QUICKLY WITH NO BRAKE FUNCTION. WE JOLTED TO A STOP AS CARS ZOOMED AROUND US HONKING AND YELLING. WHEN I TOOK THE CAR OFF OF THE PARKING BREAK, THE SAME PROBLEM CONTINUED. NO BREAKS AND SPORADIC ACCELERATION. IMMEDIATELY AFTER THIS INCIDENT A LIGHT CAME ON THAT SAID 'SERVICE STABILITRAK'. THE CAR WAS TOWED TO THE DEALERSHIP. I'M SHARING THIS FOR ALL CAR OWNERS TO REMEMBER THE POWER OF YOUR PARKING BREAK IN AN EMERGENCY. IT'S ONE THING TO BE ANNOYED WHEN YOUR CAR WON'T GO, BUT IT IS PURE PANIC AND FEAR WHEN YOUR CAR WON'T STOP AND KEEPS GOING FASTER - ESPECIALLY WITH YOUR PRECIOUS CHILD IN THE BACK SEAT. *JS PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

THE AUTOMATIC AIR SUSPENSION HAS FAILED SEVERAL TIMES WHEN TOWING. THE SHOCKS LEAK, THE COMPRESSOR DOES NOT TURN ON, AND SOMETIMES, IF IT DOES TURN ON, THE BAGS DO NOT DEFLATE. WHEN THEY DO NOT INFLATE IT CAUSES DANGEROUS SAGGING AND SQUATTING. WHEN THEY INFLATE AND DO MOT DEFLATE AFTER TOWING THE REAR SUSPENSION IS VERY STIFF AND DANGEROUS TO DRIVE AROUND IN. I HAVE TAKEN MY VEHICLE IN OVER 5 TIMES TO FIX THE ISSUE AND CHEVY HAS BEEN UNABLE TO FIX THIS PROBLEM. THIS HAS BEEN ONGOING SINCE I PURCHASED THE VEHICLE IN 2018.

Transmission will not go into drive or reverse. This also happens when car is in drive going down the road it will all of a sudden lose power and not go when pressing gas pedal. Vehicle has to completely shut off several times before it will go back into gear. No warning before it started. This can be dangerous when it happens in traffic and I can’t move car out of the road. It has not been inspected yet. Also blind spot warning does not always says it needs serviced.
