Consumer Description

I was driving on the freeway about 65 mph on Saturday June 18. In a sudden instant, there was a message on my dash "brake module failure" and "speed limited to 62 mph". Also warning message that "forward collision warning was off" , etc. The ABS light, the "check brakes light", and the check engine light all were on. Also, the power brakes went completely out and to stop I had to press really hard with manual brakes. I don't think a small framed person would have been able to stop and if I had been at a moment where I needed to stop quickly I don't think I would have been able to stop had there been a need to stop quickly. The dealer tells me that the brake master cylinder failed. The car has 43,000 miles and has been well maintained.
