2015 Acura TLX: sudden unintended acceleration

Filed May 26, 2016 · Acceleration, Transmission · 1,000 miles · CT

Can you please investigate the 2015 acura tlx with the 9sp transmission? There is unintended acceleration when slowing down, unanticipated surging, and unexpected hesitation when attempting to accelerate. This is a known issue within honda but there has been no recall or public fix from honda. I included the purchase date of the car but the above happens at various times.

Hard shifts on 1st to 2nd and 2nd to 3rd causing whiplash-like reaction. Shifts occurs after what it seems to be a pause in acceleration then engine revs for 500 to 1k RPM before shifting, then the car will lunge forward. Acura has performed software updates. It reduced the hard shifts but it is still there. I have to tighten my neck and brace for a hardshift I know is coming.

After purchasing the vehicle new, immediately noticed hard and delayed shifting. Shifting between 1-4 gears was very hard. At times transmission seemed to be confused and would either pick the wrong gear or would take 2-3 seconds to finally engage into gear. On one particular occurrence while driving in a parking lot at about 15 MPH I approached a stop sign and let off the accelerator. As soon as I let off the pedal the car dropped into gear so abruptly that it made the car lunge forward about a foot or two. On another occurrence I was driving on a residential street going around a traffic circle once again at approx 15mph I let off the accelerator for a moment as I went around the circle. Just as I was exiting the circle I depressed the accelerator to move quickly away since I saw another vehicle entering the circle. At this point the RPM's went above 3500 and the car did not shift and did not move. It appeared that the car was in neutral. It took about 1-2 seconds before the transmission was able to "find" a gear at which point it lunged forward abruptly. Both situation I did not have control of the vehicle because of the transmission. Both situations I was unable to control the vehicle in a safe manor. I have also at times needed to accelerate quickly into a merge lane and when "stomping" on the gas nothing would happen for 2-3 seconds.

1. Step on accelerator and the car jolts forward like it is in the wrong gear or you slam the accelerator, or the clutch is released rapidly. Jerks ones head back. 2.come to a stop, transmission downshifts hard causing the car to lunge forward overpowering the brake. (engine at idle). Most of the time it feels like someone has tapped you from behind. . When it occurs it is usually the first 2-3 times I come to a stop in a trip. 3.driving on level or slight decline, let off accelerator and slow to make a turn to go up a hill, step on accelerator as you transition uphill transmission slips out of gear (as if you are holding the clutch in and releasing it too slowly) then searches for the correct gear required to go up the hill and accelerate. (engine near idle) 4.most of my driving is in the city. . Stop and go. . Slow and go. . .

When driving at approximately 40 MPH the car suddenly accelerates. I first noticed problem when coasting downhill, but now occurs on level highway also. Also there are periods when one tries to accelerate from a stop or from reverse to drive that the transmission hesitates before shifting into gear. At that point the engine has revved up causing the car to lurch forward when the gear does engage. Additionally even after a recall, the parking gear slips allowing the car to roll down hill. These problems have resulted in near accidents. Updated 11/18/15*lj

The car has times where it stalls or hesitates significantly - this occurs worst in shifting from reverse to drive (there is a several second delay and then a surge forward), and there are hard shifts between 1-2 and 2-3 gears. There are also times where when coasting and you apply throttle, it is unresponsive. There have also been situations where the car downshifts very hard and lurches forward almost uncontrollably (this has only occurred in sport+ mode).
