I have a 2012 Acura TL SH-AWD Technology package. At about 37000 miles. I noticed that while accelerating at any rate of speed gradually, it will have the RPM's jump up and down ranging from 100-750 RPM's. This is happening when slightly pushing on the gas to go from let's say 40-45 or from 55-60(just slightly accelerating, not punching it). I brought it to the dealer and the manager told me she has been getting this lately on this year model with about the kind of miles I am running. I bought this car in April 2011 with 0 miles on the car. It has never done this until about 2000 miles ago. I always run premium (91-93 octane) non-ethanol gas. Always high quality synthetic oil and oil filters as well. The manager first told me this was normal for the electric throttle to do this, but after I told her that a vehicle should not do this (much less a luxury vehicle), she rephrased it and said that it has been coming up over there alot on the TL models and every once in a while on the MDX and RDX as well of the same year. She said that there is no known way to fix it and to just hold my breath that this gets addressed soon by Acura designers/engineers. It will do it from anywhere between 0-80 mphs (i don't really go over 80). My dad has owned a mechanic shop for over 30 years and says he's not sure what it is either, but most likely along the lines of something electrical like the electric throttle or something maybe tied with the transmission. Has anyone else had this issue? And if so, know a fix for it? I have not found any TSB's or recalls on it, so I'm kind of at a standstill. Any help appreciated. Thanks in advance.
