Oil consumption, engine knocking and car felt out of power specially in low in speed. Few trips to Acura but was told they couldn't find any problem. I end up getting rid of the car and after few months I bought other Tl same year and miles and unfortunately have a same problem. Its using 70 percent of oil with in a month and around 12000 miles. . . So I have to fill up oil but major issue is while I am trying to accelerate 50 percent of the time car move very slow with engine knocking sound and few times got honked because of the car coming behind me when you just made a right turn and also when taking of from stop sign or at the light it felt so sluggish . This is my 6th Tl but I never had a problem in last 4 because may be older model but last 2 2012 I have experience the same problem.

2012 Acura Tl sh-awd tech. Began to notice that I was having to have my oil changed every 2,500 - 3,000 miles. Took it to different dealers to see what the problem was. Neither dealer could find a problem. In March 2014, several warning lights came on and the vehicle would not accelerate past 20 mph. I had it towed to an Acura dealership and was told I had no oil. No warning lights or error messages ever alerted me. Beginning of April 2015 (mileage was 33k), I started hearing a knocking noise from the engine between idle and 2,500 rpm's. Again took it to the dealer. They said I had only a ½ quart of oil. They put me on an oil consumption test. Just over a month later and 1,900 miles, my car was again oil less. No leaks ever discovered. I was told I was burning oil. 1 quart to every 500 miles. Took it to the dealership and Acura replaced the engine with a new one. While I was at the dealership I was told by the service advisor that another '12 Tl was also getting its engine replaced for the same issue.
