I purchased my 2012 Acura TL tech on 4/30/12 which had 100 miles on the odometer. When accelerating at speeds between 65 mph and 80mph, there appears to be a slight vibration emitating from the gas pedal and drivers side floor. This seems to be mechanical as balancing is not an issue and it feels rythemic in nature. I have driven on this for 2 months before realizing this cannot be right. Took it to the dealer and they could not find anything, used the cookie cutter scripted "vehicle characteristic." they claim they will contact Acura tech to work through possible solutions. My concerns are when researching it appears this is a trend however no TSB's have been issued at this point. I have seen things such as axle or transmission concerns. I commute very heavily for work and chauffeur my 2 1/2 daughter around with serious safety concerns. I have probed a possible trade for another vehicle however I would have to take a $10k hit which is absolutely unacceptable. Anyone have updated fixes?

 

There was another member who started a similar thread on vibrating pedal(s) a long while back. Do a search.

 

I had the same problem on my new 2012 Acura TL. The dealer could not fix it. The head of the service department told me all of that model vibrates. I filed a complaint with Acura Corporate Headquarters and they told me it was a "vehicle characteristic." I filed a complaint with the National Highwat Traffic Safety Administration.
I PURCHASED A NEW 2012 ACURA TL ON 2/8/12. EACH DAY I DRIVE 35 MILES TO AND FROM WORK ON INTERSTATE 75 WITH A POSTED SPEED OF 70 MPH. WITHIN A FEW DAYS I NOTICED THAT WHEN THE CAR REACHED 70 MPH A PERSISTENT HIGH FREQUENCY VIBRATION CAME UP THROUGH THE DRIVER'S SIDE FLOOR AND IN PARTICULAR THROUGH THE ACCELERATOR PEDAL. BY THE TIME I REACHED WORK OR HOME MY ENTIRE RIGHT FOOT AND CALF WAS NUMB AND BUZZING. IT FELT AS THOUGH I HAD 'FALLEN ASLEEP" AND CAUSED THE NERVES TO BE TEMPORARILY NON-FUNCTIONAL. I TOOK THE CAR TO THE DEALER AND THEY TOLD ME THE TIRES WERE OUT OF BALANCE, HOWEVER, WHEN THEY CHECKED THEM THEY WERE NOT. THEN THEY TOLD ME THAT THE FRONT RIGHT TIRE HAD A TEAR IN IT AND IT WOULD HAVE TO BE REPLACED. THEY ORDERED A NEW TIRE AND INSTALLED IT AND TRIED TO CHARGE ME $399 BUT THANKFULLY THE MANAGER GAVE IT TO ME A NO COST. THE CAR HAS BEEN TO THE DEALER SIX TIMES. AT THE DEALER URGING I OPENED A COMPLAINT WITH HONDA HEADQUARTERS. FILE NUMBER B012012-04-1601260. THE REPRESENTATIVE I DEALT WITH WAS "PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),5 U.S.C. 552 (B) (6) WHO CAN BE REACHED AT "PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),5.U.S.C 522 (B) (6). THREE CALLS WERE RECORDED BY HONDA. ONE OF THE SENIOR PERSONS AT THE DEALERSHIP CONFIDED IN ME THAT EVERYONE AT ACURA KNOWS ABOUT THIS PROBLEM AND THERE IS NO FIX."PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 522 (B)(6) TOLD ME THE SAME. SHE ACTUALLY CALLED THE VIBRATION A "VEHICLE CHARACTERISTIC." VIBRATION AT 70 MPH IS NOT A GOOD THING AND IN TIME IT MAY LEAD TO CATASTROPHIC CONSEQUENCES. BOTH ACURA AND THE DEALER REFUSED TO BUY ME OUT OF THIS VEHICLE AND SO LAST SATURDAY I TRADED OUT TO ANOTHER CAR AT A SUBSTANTIAL COST TO MYSELF. *TT UPDATED 07/09/12

At three months I traded the car for a 2012 Mercedes C300 and lost thousands of dollars. I am in the process of suing the dealer and Acura. The car is a piece of trash. Do you notice how it is virtually never advertised on TV?

 

OP, ever get this resolved? First thing I would do is have the tires rotated and balanced and see if that changes the vibration.

 

I'm also having the similar issues
