Driving 2012 Chevrolet Sonic approximately 50mph, car down shifted on its own to 20mph nearly getting rear ended. Tried driving in auto transmission and manual mode, transmission stuck in 3rd gear. Had to drive 11 miles on busy road at 20mph, speed limit is 50mph. Car is at dealer, has turbine shaft break and wave plate broken. Because car has 1-2012 on sticker, no warranty is available. My option is $4800 to replace transmission or junk it. Car only has 93 thousand miles and was always mainted very well, lucky there was no injuries.

On Sunday, my transmission had a Complete Failure; according to the dealership, on Monday afternoon, we had the vehicle towed to Pinkerton in Salem 925 N Electric Rd, Salem, VA 24153 540-562-1337. The vehicle has only had 48,900. They said that there was a flaw possible in the transmission but have been waiting to see if they have a fix for the problem since it was possibly a manufacturing issue since the vehicle was service regularly at the dealership. We were on the highway when this was happening, and the vehicle what to stall out, so we had to come home. On Monday, we had the vehicle towed since it would not reverse out of the driveway.. No warning light, and the car was driving fine until 07/25/2021

Shift Lever (Gear Shifter) started getting stuck in park when I attempted to put it in drive. My vehicle key would also get stuck in the ignition. These two problems put my personal safety at risk because in not being able to shift from park to drive and (or) take my key out of the ignition, I would be left stranded out in public.

DURING STOP-AND-GO CITY TRAFFIC, THE CAR WILL STRUGGLE TO CHANGE GEARS, AND HAS (BETWEEN 5-10 TIMES) "STOPPED RESPONDING," MEANING THAT THE CAR IS UNRESPONSIVE TO PRESSING THE BRAKE OR GAS, ALTHOUGH THE ELECTRICAL SYSTEM CONTINUES TO RUN. THE ONLY SOLUTION WE HAVE FOUND TO THIS IS PUTTING THE CAR IN PARK, TURNING IT OFF, AND TURNING IT BACK ON AGAIN, BUT THIS IS VERY SCARY IN THE MIDDLE OF TRAFFIC. THIS HAPPENED MOST RECENTLY ON 5/8/21 BUT HAS HAPPENED AT LEAST 5 TIMES IN THE PAST 18 MONTHS.

FIRST PROBLEM STARTED WHEN RADIO REMAINED ON AFTER KEY REMOVED FROM IGNITION. RADIO WOULD TURN ON AND OFF WHEN CAR WAS OFF AND DRAINED NEWLY REPLACED BATTERY. ADVISED TO REMOVE FUSE AS TEMPORARY FIX. CAR WAS ALSO LOSING POWER WHEN HIGHWAY DRIVING (UP TO 70 MPH). I DON'T SPEED, BUT CAR STRUGGLED TO GO ABOVE 70 MPH. THOUGHT I SMELLED SOMETHING BURNING, HAD RADIATOR CHECKED, OIL CHANGED, FLUIDS ADDED AT BEGINNING OF OCTOBER. THREE WEEKS LATER ON CITY STREET, SLOWING FOR TRAFFIC WHEN CAR LOST POWER. WHEN TRAFFIC STARTED MOVING, CAR CONTINUED TO SLOW TO COMPLETE STOP IN THE STREET DESPITE STEPPING ON GAS. WAITED 25 MINUTES FOR TOW, BUT WHEN TOW DRIVER CAME, CAR WAS ABLE TO START AND MOVE. LESS THAN AN HOUR LATER, THE PROBLEM HAPPENED AGAIN AND CAR WAS TOWED. AT MECHANIC, COMPUTER CODES INDICATED LOW/NO TRANSMISSION FLUID (EVEN THOUGH FLUID WAS ADDED AT OIL CHANGE ONLY THREE WEEKS PRIOR). NO EVIDENCE OF LEAKS. MECHANIC ADDED FLUID AND WENT FOR RIDE ON SUBURBAN BACK ROAD, CAR LOST POWER AFTER 10 MINUTES. HE HAD TO WAIT APPROX 20 MINUTES FOR CAR TO MOVE AGAIN. HE DRAINED TRANSMISSION FLUID AND FOUND METALLIC BITS, AND SAYS TRANSMISSION WOULD LIKELY NEED REPLACING. CAR HAS FAIRLY LOW MILEAGE '54K MILES' AND HAS BEEN PROPERLY MAINTAINED. ALSO CAR WAS PREVIOUSLY SERVICED BECAUSE KEY WAS STUCK IN IGNITION.

I OWNED MY 2012 CHEVY SONIC LT FOR EXACTLY 8 YEARS, WITH ONLY 81.3K MILES ON IT. AFTER ABOUT 2016, IRONICALLY, WHEN IT WAS PAID OFF, IT STARTED TO 'NICKEL & DIME' ME; WITH EVERYTHING FROM ELECTRICAL ISSUES, TO BATTERY REPLACEMENT SEVERAL TIMES, IT SEEMED I WAS CONSTANTLY TAKING IT TO THE SHOP. I WAS ALWAYS VERY TIMELY WITH REGULAR OIL CHANGES AND MAINTENANCE BUT REGARDLESS, UNBEKNOWNST TO ME, THE 2012 MODELS OF THE SONIC HAVE TRANSMISSION/POWER TRAIN ISSUES THAT THE MANUFACTURER MADE SURE WERE ADDRESSED IN THE 2013 MODELS BUT FAILED TO RECALL OR PAY FOR THE FAULTY TRANSMISSION FOR THE 2012 MODELS. I HAD NO INDICATION MY TRANSMISSION WOULD FAIL ON ME SO SUDDENLY. ON SEPT. 14TH, 2020, I WAS BACKING OUT OF MY DRIVEWAY, AND WHEN I STARTED DOWN MY STREET, I NOTICED MY CAR WASN'T ACCELERATING PROPERLY. I THOUGHT IT WAS MY IMAGINATION AT FIRST, BUT IT CONTINUED GETTING WORSE TO THE POINT WHERE A HIGH-PITCHED WHINE STARTED AND I IMMEDIATELY PULLED OVER - MY CHECK ENGINE LIGHT CAME ON AT THAT TIME ALSO - AND THAT WAS THE BEGINNING OF THE END. I HAD MY CAR TOWED TO MY AUTO SHOP AND THEY WROTE ME A QUOTE FOR $5200 TO HAVE MY TRANSMISSION COMPLETELY REPLACED. IT WAS THEN THEY TOLD ME ABOUT THE 2012 SONIC FAULTY POWER TRAIN ISSUES. I THINK IT'S COMPLETELY UNETHICAL TO NOT ADDRESS A KNOWN ISSUE THAT COULD'VE BEEN TAKEN CARE OF BY THE COMPANY SINCE IT WAS THE FIRST YEAR THE CAR WAS SOLD, IT SHOULD BE THEIR DUTY. I HAD NO CHOICE BUT TO SELL THE CAR FOR PARTS AS IT WASN'T WORTH THE RESALE VALUE WITH SUCH A MAJOR ISSUE.

I WAS DRIVING AND TURNING LEFT INTO A PLAZA PARKING LOT WHEN ANOTHER VEHICLE HIT MINE VERY HARD AS THEY WERE GOING REALLY FAST. THEY HIT THE FRONT END OF MY VEHICLE COMPLETELY DAMAGING THE GRILL, FRONT BUMPER AND ALL OF THE SUPPORTS FOR THEM. EVEN THOUGH MY CAR TOOK A HARD IMPACT BY ANOTHER VEHICLE, THE DRIVER'S SIDE AIRBAG DID NOT DEPLOY. I, AS WELL AS THE COPS THAT WERE ON DUTY, WERE VERY CONCERNED BY THIS FACT.
