Brakes failed on three consecutive days during cold spell (teens with wind chill -10 to 10F) the first time I had pulled out of a parking space at the supermarket and was heading towards the exit. I noticed that the car was not slowing as I approached the street although I was exerting considerable force on the brake. I managed to stop the car and pull to the side of the street. I checked for any physical obstructions and did not find any. The brake pedal would not travel. After a few minutes the brakes resumed normal operation and I was able to carefully drive home. The next morning, I pumped the brakes with the car off until the pedal would not move. I then turned on the ignition and noticed the brake would not go down again. I had to wait a few minutes until it functioned again. Third instance, I started the car and pumped the brakes several times. The first couple times it worked but then it froze again. After some more time, the brakes engaged and I took the car to an auto repair shop. This is a very dangerous situation and I feel fortunate that I did not run anyone down in the crowded supermarket parking lot and the street was clear when I couldn't slow the car and rolled into it.

This is the second time this has occurred. The first time was about 3 weeks ago and since it had never occurred before, I believed it to be an anomaly. Second time...no longer an anomaly, this car has a breaking problem that is being ignored by Acura. On two occasions now my breaks have failed within the first few minutes of vehicle operation causing me to have to use my emergency break in order to avoid being T-boned by oncoming traffic. When I was approaching the stop sign I attempted to break only to find the break pedal solid and stiff and would not move no matter how hard I pushed. I had no breaks whatsoever. Within a short time after, the breaks started working. Conditions on both occurrences were temperatures below 10 degrees with a negative wind chill and I had not warmed my car up prior to driving it. The second time I was dangerously close to getting T-boned by oncoming traffic on the drivers side. The only reason I was not hit was simply because I had the presence of mind to pull the emergency break. This time I immediately parked the car and called for a tow truck. The vehicle is sitting at a Honda repair shop as there are no Acura dealers close. I contacted Acura and was told there were no service bulletins on this and that the car is out of warranty however a local advocate for my region would call me back on Monday. Today is Friday. Someone needs to investigate this as when I search the forums tsxclub.com (breaks fail when cold), there are multiple owners experiencing this issue. There are also cases on this site as well. Acura needs to acknowledge this issue and issue a recall on these vehicles. I cannot imagine what would have happened if this would have happened when my teen driver was behind the wheel.

The brake does not work during winter and morning when it's cold. The pedal gets stiff and does not work. But after 5 mins of engine running or after several steps on pedal the brake works. This was checked in the dealership but service department said it was normal.

The speed did not go down quickly when I broke. I gassed a little bit, then did brake 2-4 seconds genteelly, but the speed did not go down significantly.

Brake pedal is freezing. Why is this not a recall!? it was a cold morning (3 degrees F). I warmed up the car, left my road and, as I approached the light at the main road, I went to apply the brakes and the brake pedal was like a rock. It wouldn't move. I'd already applied the brakes several times before getting to that point. I looked down at the pedal to see if anything was in the way. With little time to react and the gear shift reading like war and peace in that moment, I threw the car into park to try to reduce the impact as I hit 2 of the cars at the light. I immediately called 911. While on the phone with them, I heard a hissing sound and the brake pedal finally gave way. I phoned the dealer and was told the same thing happened to two other people that day--just from that one dealership. I got nowhere with them because I was out of warranty. I called Acura corporate and they could not have cared less. They asked what I wanted and I said, "I want you to care about why your brake pedal is freezing." With my car still at the body shop, I phoned the dealer again. They said they think it's a faulty check valve and vacuum line that lets condensation freeze in the line. And guess what" those parts happened to be on a national back order...but there's no recall!??" I went to the dealership and met with the general manager, who agreed to provide me with a loaner until the parts came in after the body shop was done with my car. The plan was to drive the car slowly from the body shop to the dealer. But then the body shop called to tell me the brake pedal froze on them as they went to pull it into the garage to work on it (again, it was a cold morning). They didn't feel comfortable letting me drive it so called the dealer on my behalf who agreed to pick it up and tow it to the dealership. It hasn't happened since the repair but it hasn't been that cold.

Acura Tsx 2010 rear brakes are prematurely wearing. During last visit to the dealer (around 27,000 miles) I was told that my rear break pads have only 3mm of ceramic left. I was very surprised by this news, but did not get them replaced at that time. Now I went ahead and replaced rear break pads myself and was very shocked to see that the pads that are in contact with calipers are almost gone while pads that are on the outer side of the wheel still have more than 50% of life left in them. I will save the break pads so let me know if you want to see them.

I was very surprised to hear that my rear brakes needed replacement after only 24,800 miles. I had only taken my car in for the normal oil changing and tire rotation. My normal daily commute is to and from work totaling 50 miles, with the occasional short stop at a grocery store. When my husband questioned Acura if there were any complaints or recalls about the premature wearing of 2010 Tsx brakes, they stated they hadn't heard anything. (I had previously owned a Honda Accord and I had similar problems with the brakes on that car as well.) so my husband and I decided to look the information up online and there seems to have been a class action lawsuit filed indicating that certain Honda and Acura year models had complaints of premature wear on brakes. Apparently in the settlement you can submit your information and receipt to the settlement administrator and receive up to $150 back for the replacement of the new brakes. When I called the settlement administrator to verify that my car was included in this reimbursement settlement, I was informed, to my disappointment, that my car did not qualify. It seems that several people have had similar problems with premature brake wear and yet they only marked certain cars for replacement? evidently this is an ongoing problem with these certain year models and Acura should stand behind their product and replace the brakes without the customer having to go through the surprise and cost of replacing their brakes prematurely. Apparently the only way a recall will be made or anyone will take this problem seriously is if someone is badly injured or even killed when their brakes do not respond or respond improperly. If Acura/Honda does not address this issue, with the safety of its customers in mind, my husband and I will have to seriously contemplate doing business with a different company altogether.

Acura Tsx 2010 rear brakes are prematurely wearing. Rear brakes down to 75% use left after only 40,000 miles. Class action lawsuit existed but has expired. My car was not in the list of approved vins for the lawsuit, but my car is experiencing the same known issue. Local non-Acura repair shop says it is a known issue and is due to the calipers binding up. Acura needs to replace the calipers and brakes at no cost.

I took my 2010 Acura Tsx in for periodic maintenance (A-1). I was advised by the service representative that my rear brakes were worn down to 3 milliters and would need replacement soon. I asked if there was a recall or class action suit on these brakes and was told that there was for Honda and Acura Tsx's up to 2009. Apparently the actions taken by Honda/Acura are insufficient. Acura wants over $300 to replace the pads and surface the rotors. Apparently Honda is offering discounts of $150 for the service under the terms of the class action suit, which doesn't cover my particular Acura. However resurfacing the rotors cannot be done every 20,000 miles without needing early replacement of the rotors. Who pays for that" I was going to wait to take the car in for service. I wonder how serious this would have been if the rear brakes had failed during the ensuing period"
