2012 AUDI A7 Power Train Problems

I have seen at least three other complaints with NHTSA on this same item all with different headings. Check engine light comes on at high speeds while highway driving. Pull Engine code and comes back as P2753 - Valve for transmission fluid cooler circuit open. Had to replace coolant control valve for transmission as coolant was leaking into solenoid.

I BOUGHT A 2012 AUDI A7 PRESTIGE FROM CARVANA ONLINE IN DECEMBER 2019, FEW DAYS BEFORE CHRISTMAS. AT THE END OF JANUARY, I'D AN ISSUE WITH MY CAR, WHICH NEEDED IT TO GO TO THE SHOP FOR REPAIRS. AT THE SHOP, I FOUND OUT THAT MY WHEELS WERE STAGGERED AND THAT THE VEHICLE WAS LOWERED THAN ITS ORIGINAL SPECIFICATION AND RECOMMENDATION. I CONTACTED CARVANA AND SILVERROCK, AND A CLAIM WAS INITIATED ON 02/09/2020 AT 1:58PM. I WAS TOLD TO TAKE MY VEHICLE TO A SHOP AND HAVE THEM CONTACT CUSTOMER SERVICE.

MIND YOU, WHEN I BOUGHT MY CAR FROM CARVANA, THERE WAS NEVER A DISCLOSURE OF THE WHEELS BEEN CHANGED. CARVANA CLAIMS THEY...

VEHICLE STALLED WHILE DRIVING. UPON INSPECTION BY THE DEALERSHIP, I WAS INFORMED THAT A COOLANT VALVE CONNECTED TO THE TRANSMISSION CONTROL MODULE HAD FAILED. THIS RESULTED IN COOLANT LEAKING INTO THE MODULE AND THEREBY DAMAGING IT. THIS IS A KNOWN DEFECT IN A SIMILAR VEHICLE OF THE SAME YEAR.

CHECK ENGINE LIGHT CAME ON SO I TOOK IT TO THE DEALERSHIP. DEALERSHIP TOLD ME THAT THE "COOLANT VALVE LEAKED INTO THE WIRING HARNESS AND SHORTED THE ENGINE CONTROL MODULE. MAY HAVE CAUSE AN UNEXPECTED STALL OF THE VEHICLE."
