After owning my 2012 Acura TL for roughly 2yrs, I've become concerned with the engine workmanship. Acceleration seems to be at a loss between 30-45mph in between gear changes. It's almost as though the transmission doesn't know what to do. You have to either let up on the acceleration or increase your speed to avoid that annoying hesitation. The second problem is what I would describe as lifter/valve noise. The noise occurs when accelerating, intermittently though. Although it is embarrassing driving a vehicle that looks as good as the TL looks and have it sound like an old Chevy when you accelerate, I hate it. I took it to the dealer, they could not replicate the noise, of course. They told me the car was fine. I told them specifically I believed the noise was coming from lifter/valve. They told me it was probably poor gas selection. I explained to them I used the recommended premium octane/chevron. They had no answer. Lastly, my brakes are squealing, I told the Acura mechanic to please check my brake pads, he said they were perfectly fine and should not worry. He said the rotors develop a blue film over time, and the squealing noise is normal. I couldn't believe it, I am supposed to accept that annoying brake noise. This is not what I expected from Acura/Honda, is this bad workmanship or poor materials being used by Acura to keep costs down on manufacturing.

After accelerating from a stop and shifting from first to second gear, the vehicle lost all engine power. The engine did not stall and the RPM's did not drop, but the gas pedal did not respond to input. The vehicle just coasted. After prodding the gas pedal multiple times, it began to respond and I was able to accelerate onto the highway. The issue lasted for about 3-5 seconds. It felt as if the gas pedal was disconnected.

Purchased my new 2012 sh-AWD Acura TL advance in March of 2012. The car had less than 100 miles when purchased and currently has 5K miles (January 2013). The car vibrates when driving at speeds between 40 and 80 mph. It feels like the tires are flat spotted or wheels are out of balance. The wheels and tires have been checked and confirmed by the dealer on 2 separate occasions as ok. The dealer classified this vibration as a "vehicle characteristic." I'm worried it is the sign of a major issue they don't want to deal with.

Turned corner in large center city and hit a construction large pot hole and/or obstruction on the left rear. After completing turn onto a narrow one-way street acceleration increased, brakes did not work, engine could not be turned off, gears could not move. After going through two major intersections without accident I kept pulling on the emergency brake. The car slowly stopped and was then perfectly normal. Could use the brakes, shift, etc. I parked overnight in a garage. Had the car towed to dealer the next day (7/21/12), where it is still unresolved. Dealer said car is ok, but is now being analyzed by Acura corporate engineers. I had three other people who were in the car at the time, including my wife, who will not ever go into this car. The car was only 10 days after purchasing.

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 imitating from the gas pedal and drivers side floor. This seems to be mechanical as balancing is not an issue and it feels rhythmic 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. Please open a case to research this issue!

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. Updated 07/09/12
