Car has 4 trips on rollback and one driving in for transmission problems 3 trips was when coming to a stop the car will will slide to stop almost making us hit dash of car each time there would be a warning about a minute before service transmission . One of the Trip for transmission service light I did drive it in. The car went in yesterday for transmission service again. My thinking of this is what would happen if I were driving 70 MPH and the car locked up what would happen to me and the people around me.

I PURCHASED MY VEHICLE IN JUNE OF 2018. THE CAR DROVE BEAUTIFULLY FOR ABOUT 14000 MILES. THEN I STARTED NOTICING HARSH SHIFTS AT LOWER SPEEDS, SHIFTED FINE ON THE HIGHWAY. THIS CONTINUED ON AND I JUST THOUGHT IT WAS NORMAL WEAR. THEN ABOUT 2 MONTHS AFTER THE HARSH SHIFTING STARTED I WAS GETTING ON THE HIGHWAY AND ACCELERATING UP TO SPEED. I THEN LET OFF MY GAS PEDAL AND THE CAR STUCK IN GEAR. I TRIED SLOWING DOWN AND SPEEDING UP AND THE CAR WOULD NOT SHIFT. I HAD TO PULL OVER SHUT THE CAR OFF AND TURN IT BACK ON DURING RUSH HOUR. THIS HAPPENED AGAIN ABOUT A MONTH LATER, SO I CALLED TO MAKE AN APPOINTMENT AT THE DEALER. TOOK MY CAR IN AND THE SERVICE TECH ASKED ME TO RIDE WITH AND SHOW HIM WHAT IT IS DOING. SO I DROVE THE TECH AROUND ABOUT A HALF HOUR. ON THE WAY BACK IN TRAFFIC AT ABOUT 35 MPH THE CAR STUCK IN GEAR AGAIN WITH THE TECH IN THE CAR. THEY HAD THE CAR A WEEK AND CUD NOT REPLICATE THE ISSUE AGAIN. THEY TALKED ABOUT REPROGRAMMING MY ANS BUT SINCE NO REPORTED PROBLEMS THEY COULD NOT DO IT. I HAVE HAD THE CAR BACK A MONTH AND IT HAS HAPPENED TWICE AGAIN. SO I WILL YET AGAIN MAKE ANOTHER APPOINTMENT. THIS IS VERY UNSAFE WHEN THE TRANSMISSION WILL NOT SHIFT TO HAVE TO TRY AND PULL OFF ON BUSY HIGHWAYS WHERE THERE ARE NOT ALWAYS SAFE PLACES TO DO SO.

THIS PROBLEM ALSO EXISTS SHIFTING UP AND DOWN GEARS. TOOK IT TO THE DEALER TO GET SERVICED. THEY FLUSHED THE TRANSMISSION, REPROGRAMMED THE TRANSMISSION CONTROL TO NO AVAIL. THE PROBLEM OCCURS WHEN THE ENGINE IS COLD AND HOT

I HAVE NO IDEA WHETHER THIS CONCERNS THE TAKATA INFLATORS OR NOT. WHILE ACCELERATING FROM A NORMAL TRAFFIC SPEED (APPROXIMATELY 20 TO 40MPH) , IT SEEMS LIKE THE TRANSMISSION SHIFTS UP AND DOWN RAPIDLY SEVERAL TIMES BETWEEN LOWER GEARS. IF THE ACCELERATION IS TERMINATED BY BY LIFTING YOUR FOOT FROM THE ACCELERATOR, THE SHIFTING GOES AWAY. AFTER THAT, A SOFT PRESSURE ON THE ACCELERATOR WILL ALLOW THE VEHICLE TO ACCELERATE WITHOUT FURTHER UNWANTED SHIFTING. THIS IS A REOCCURRING PROBLEM.

I ALSO FELT UNSAFE DRIVING AT LOW SPEED WITH THE EMERGENCY LIGHTS ON THE HIGHWAY. I FELT UNSAFE STRANDED ON THE HIGHWAY IN THE VEHICLE, WAITING FOR THE TOW TRUCK. *TR
