Filed NHTSA Complaint, The surge in downshift is dangerous

10K views 15 replies 11 participants last post by  enterprise 
Took Car to dealer today, test drove with TECH, confirmed hard up shift from 2nd to 3rd, Car surges before it downshifts in sports or using paddles (all gears, some more that other). I told him about another weird thing that happens when making a long 90 degree right hand turn. Mid turn, i lose all power to wheels (no stall) then power comes back as I straiten out of the turn (when tyran/engine cold). Anyone else experience this?
He also confirmed the tick in engine is direct injection. He said he had another TLX (in the shop) that exhibited my traits and some others and was expecting an ECU update that was to fix these problems yesterday (2-9-15) but had yet to receive them and to call back end of week /next week to see if they have the update. WILL believe it when I see it.
Filed NHTSA Complaint, The surge in downshift is dangerous if not expected.
Bulldog, I find the downshift surge only occurs in Sport+ mode. Is it the same for you? Or does it happen in Sport also?
