Could be transmission or engine mount is loose, and the powertrain is rocking back and forth. See if it does the same thing in reverse (safely).I have a 2013 PF - when I accelerate and immediately remove my foot from the gas pedal, I hear this tap or thump just under my feet. I guess that where the transmission is. Is this normal?
at least its gone now. hopefully it doesn't come back and if it does you still have your warrantyOf course, I took it to the dealer...all the while replicating this issue. As soon as I got to the dealer...they test drove, and couldn't replicate it. I drove and couldn't replicate it. It's gone. But it definetely was there. A light thump noise, almost is if I was running over somthing and it was bouncing off the bottom of the car. Most noticiable as I was accelerating from a stop and then immediately taking my foot off the pedal. Maybe a bit worse on an incline. Well its gone now...so maybe had something to do with the ABS brakes adjusting...but that should only happen once. I have only 750 miles on my car. Love it
It would be great if you could post a pic of the area you've identified.I have noticed this a couple of times on our 2013. When it starts it is consistent and easy to replicate, usually lasting several days before going away on its own. Seems to be weather-related.
No guarantee this is the root cause, but I can duplicate the sound and feel of the thump by sliding under the vehicle and pulling down on the edge of the plastic pan directly under the driver's footwell. There is some sort of tacky adhesive or padding material where the plastic pan presses against the metal frame. The thud happens when the tacky material separates from the metal.
Placing a piece of masking tape between these two parts seemed to stop the thumping, but does not explain what is causing the flexing or shifting that presses them together and then pulls them apart. Hopefully not a sign of more serious issues down the road!
Have you put it up on a rack to take a look, might be something loose or might be with the CVTI have a 2013 PF - when I accelerate and immediately remove my foot from the gas pedal, I hear this tap or thump just under my feet. I guess that where the transmission is. Is this normal?
