NHTSA Complaint #11080053 — 2013 CHEVROLET SONIC

TO BEGIN, I HAVE BEEN HAVING A SHIFT FLARE PROBLEM WITH MY AUTOMATIC TRANSMISSION. THERE ARE NO TROUBLE CODES IN THE SYSTEM. THIS WOULD HAPPEN WHEN I WOULD GET OFF THE HIGHWAY WHEN THERE WAS A LOT OF TRAFFIC OR WHEN THE CAR WAS RUNNING FOR A LONG TIME. THE PROBLEM WENT AWAY WHEN THE CAR WAS COOLED AND WAS PARKED FOR SEVERAL HOURS. THE RPM WOULD SPIKE ABOUT 200RMP WHEN ACCELERATING. THIS WOULD HAPPEN FROM 2ND TO 3RD GEAR. I HAVE CHANGED THE FLUID AND I HAD TO PUT A LITTLE MORE THAN HALF A QUART OF FLUID INTO IT. THE TRANSMISSION IS LEAKING FLUID. ONE THING THAT I NOTICED WAS THAT THE DRAIN PLUG BACKED OUT. I DON'T KNOW WHY THIS HAPPENED BUT IT LEAKED AROUND IT. THERE IS ANOTHER SMALL LEAK WHERE THE ENGINE AND TRANSMISSION MEET. THIS IS A VERY SMALL LEAK AND IT ONLY LEAKS IN FREEZING TEMPERATURES. THE LEAK THAT HAS BEEN HAPPENING WHERE THE ENGINE AND TRANSMISSION MEET HAS BEEN HAPPENING FOR ABOUT 2 YEARS NOW. I HAVE BROUGHT THE VEHICLE IN TO HAVE SOMEONE TAKE A LOOK AT IT AND THEY SAID THAT THERE WAS NO LEAK. AT 60-65K MILES, THE FLUID IS A SOLID GLOSSY BLACK COLOR.
