2012 Acura TSX Brakes Problems

“Power brake booster check valve sticks in cold weather negating power assistance. This came to my attention with seattle's recent cold spell (feb 2019). Check valve located within master tube assembly (46402-tl2-a11) which is on backorder across all states that experience winter weather. I've spoken to numerous dealers and scouring the internet, this is a common problem. Additionally, I contacted Acura twice and was told follow up would be immediate, with zero response to date.”

“I lost power steering driving to work at interstate speeds a couple of weeks ago. I have been driving this route to work for many years and this experience startled me. This situation could have become fatal very quickly with a less experienced driver.the replacement cost is expensive and the eps module needed for repair is not easy to find. None of the local Acura dealers will work with me so my car is sitting in a storage yard while I try to figure out what to do. As a result, I am without a car to get to work everyday. …”

“First thing in the cold morning my brake pedal was solid, no movement when I press it, and thus no brakes. This is the 2nd time, but the first time (a week ago) I thought I did something wrong because it went away quickly. This morning I almost drove into traffic. And after I entered the road, it took a few minutes before the brakes returned to normal. I'm guessing there is some moisture in the brake line that is frozen and eventually it thaws and the brakes return.”

“A car stop in front of me quickly so I push the brake hard to stop and I heard the ABS grinding, so everything fine, I continue driving then I want to stop on the stop sign and I found the brake pedal is not normal I have to push it completely down feels like no brakes I took it to Acura dealer and they flash the brake oil, and I told them what happened they said no air in the ABS or the system and its normal but if it happen again you need ABS control module the car mileage is 109000 and its all highway miles. Now when I push on the pedal it feels spongy and it goes to the floor. …”

“In cold weather the brakes feel 'frozen' or 'wooden', and do not perform correctly. The car will not stop. After using them a few times in a row they seem to return to warm weather performance. It happens again every time the car is driven in cold weather' not extreme cold, but just near freezing. It seems to have started early this year. Service people cannot see a cause.”
