2011 Chevrolet Impala

ON TWO DIFFERENT OCCASIONS, ONCE ABOUT A YEAR AGO AND AGAIN TODAY, MY 2011 CHEV IMPALA LTZ DISPLAYED A SERIES OF ROTATING ALERT MESSAGES -- 1. SERVICE TRACTION CONTROL 2. SERVICE STABILITRAK 3. ENGINE POWER IS REDUCED. I WAS DRIVING ABOUT 45 MILES PER HOUR ON AN OPEN ROAD WHEN ALL OF A SUDDEN THE ENGINE STARTED RUNNING VERY ROUGHLY AND SLOWED DOWN AND THE ABOVE 3 MESSAGES REPEATEDLY DISPLAYED ONE AFTER THE OTHER. ALSO 2 YELLOW LIGHTS WERE FLASHING AND THEN REMAINED ON -- THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT (I THINK). WHEN I REPORTED THIS PROBLEM TO THE CHEV DEALERSHIP A YEAR AGO, I WAS TOLD THAT BECAUSE THE WARNING LIGHTS AND MESSAGES COULD NOT BE REPRODUCED IN THE SERVICE DEPARTMENT, THERE WAS NOTHING THAT THEY COULD DO. (AND I UNDERSTAND THAT IF IT ISN'T BROKEN WHEN I TAKE IT IN, THE SERVICE DEPT WOULD MOST CHALLENGED TO FIX IT.) TODAY, WHEN THIS HAPPENED I WAS ABLE TO GET THE CAR TO A SAFE PLACE TO PARK. I TURNED OFF THE IGNITION, WAITED A MOMENT AND THEN RESTARTED THE CAR. THE SAME 3 MESSAGES WERE DISPLAYED WITH THE TWO YELLOW LIGHTS STAYING ON. WHEN I RESTARTED THE CAR 3 OR 4 HOURS LATER, ONLY THE CHECK ENGINE LIGHT IS DISPLAYED. THE 3 REFERENCED ALERTS WERE NOT DISPLAYED. I AM GETTING READY TO TAKE THE CAR TO THE DEALERSHIP AGAIN WITH THIS PROBLEM. DO YOU HAVE ANY ADVICE AS TO HOW TO PROCEED?

IT WAS DRIVING ON MY WAY BACK HOME. THEN THE ENGINE LIGHT CAME ON THE DASH SAID REDUCING ENGINE POWER BUT THEN THE TRACTION CONTROL LIGHT CAME ON AND AND THE ABS LIGHT CAME ON SO WHEN I GOT HOME I PARK THE CAR AND LEFT IT ALONE THAT DAY..THE NEXT DAY I TURN THE CAR ON AND THE ABS LIGHT IS ON AND THE TRACTION CONTROLL LIGHT IS ON I DRIVE THE CAR IT FEELS LIKE IF THE BRAKES ARE ON I HEAR A NOISE OUTSIDE THE CAR SO I TAKE IT TO A NEAR SHOP AND THEY TELL ME ITS A BAD WHEEL ROUTER SO I CHAGE IT FOR 180 AND IT WASNT THAT SO I SEE ALOT OF IMPALAS DEALING WITH THE SAME PROBLEMS

JUNE 8 2013: WHEN DRIVING, NOTICED ON THE FREEWAY, IT WASN'T SMOOTH AT TIMES. THE TRANSMISSION'S SHIFTING WAS PRETTY ROUGH. NO INDICATION OF ANY ISSUES POPPED UP ON DASHBOARD. WHEN ARRIVING AT FREEWAY RAMP, IT FELT LIKE I WAS HYDROPLANING, BUT ON GRAVEL. THEN, NOTICED WHEN PRESSING THE ACCELERATOR, WAS NOT GOING ANYWHERE, BUT FELT LIKE I WAS IN NEUTRAL. WAS ABLE TO PULL IN AND TAKE A LOOK... TRANSMISSION FLUID WAS FINE... NOTHING POPPED UP ON THE DASHBOARD. NOTHING! THE INDICATORS FOR TIRES, OIL, ETC WERE SHOWING INFO, BUT NOTHING TO INDICATE IT HAD DIED!! DROPPED IT OFF AT THE DEALERSHIP - HAD JUST BOUGHT IT IN JULY 2012. 11 MONTHS LATER, THIS?!?!? THEY ARE SAYING THEY HAVE NEVER SEEN IT THIS BAD, EVEN WHEN COMPARED TO OTHER OLLLLLLDER CARS, THIS WAS THE WORST. THEY HAVE TO REPLACE THE ENTIRE TRANSMISSION. THEY CALLED IN THE GM PEOPLE TO TAKE A LOOK AT IT.THEIR AUTO TRANS CONCERN: CUSTOMER STATES TOWED IN TRANSMISSION WILL NOT MOVE AT TIME OF WRITE UP REVERSE AND FORWARD WORKING INPUT AND REACTION CARRIER EXCESSIVE CLEARANCE METAL IN TORQUE CONVERTER., VALVE BODY, BURNT CLUTCHES CALL TAC CASE #71-1194752825 PRIVE COMP ADVISED TO REPLACE TRANS DUE TO COST WITH SRTA. ORD SERIAL #619ASBWJR6J PRELACW TIH SRTA FLUSH CODE 693FFEE5 THEY REPLACED IT UNDER WARRANTY... TOTAL COST WAS $4400 AUG. 29, 2017. THE REPLACED TRANSMISSION FAILED. WE WERE ON THE FREEWAY, JUST GOT OFF, WHILE IN MOTION, THERE WAS SOME REALLY ROUGH VIBRATION. COULD NOT GO ANY FASTER THAN 25 MPH. NO LIGHT INDICATIONS ON THE DASHBOARD. IT TELLS ME IF FLAT TIRE, BLINKER IS ON, THE TEMPERATURE OUTSIDE, ETC ETC, BUT NOTHING WRONG WITH THE TRANSMISSION. I'M NOT SURE IF IT'S RELATED, BUT WE SMELLED VINEGAR EVERY TIME WE STARTED THE CAR FOR ABOUT 4 DAYS STRAIGHT. WE NOTICED THAT WHEN ACCELERATING, IT'S OKAY, BUT WHEN LETTING OFF THE GAS ON THE FREEWAY, IT "SHUDDERS."
