problem #2

Jan 262015

TSX Premium 2.4L

  • Automatic transmission
  • 48,467 miles


During cold nights (-10 to -30 degrees C) after starting the car in the morning to head to work, the brake pedal would not move. Stuck solid from its position. Let the car warm up and the brakes would work again. Was a reoccuring event, advised Acura, took it to the dealership and they replaced a brake valve I believe. Corrected the problem. Many other people online have complained about this as well. The Acura dealership was a pleasure to deal with and resolved my problems under warranty.

TSX 2.4L 4 cyl

My brake pedal has no movement first thing on a cold morning, almost zero braking power. It takes a few minutes (so far) to get warm I'm only guessing here, and then the brake pedal drops down 1 -2 inches and behaves normally. The first time it happened it went away so quickly I forgot it happened figuring perhaps i did something wrong. But a week later, this morning it happened again and I almost drove into traffic. I've read a couple places already, this site and others, that this seems to be a pervasive problem in cold weather. I am nervous that the dealership is going to give me the run a around blow off like I've heard from others with this failure.

I will update after I get a chance to bring it back to the dealership.

Update from Feb 11, 2015: The dealership fixed it. I left it over night at the dealership, fortunately the next morning temperatures were below 0° F, and the brake failure was seen. The fix is a new check valve for the brake boosters. Which is a fix I found on some TSX forums. But I asked the dealership if they can research other dealerships to find a diagnosis, they pretended that they cannot and the brake failure would have to be exhibited for them to find a solution.

Either way, the brakes work great now, and I can love the car again. But beware in the cold, try your brakes in a safe place before you enter traffic. And if you exhibit this brake failure, it's most likely the check valve for the booster.
