Brake failed and battery light on while start
I have a 1999 Taurus. The "service engine soon" light was flashing, and a mechanic said one of the 6 cylinders failed. There was no other problem (as he said) and the cost to fix is too high so he suggest we continue driving the car without fixing the problem (until other problems fail the car). It worked well, for 4 months. Yesterday when I started the car, and shift to "R", I noticed the brake failed (so it kept moving), and battery light was on. I had to shift to "P" to stop it. Then I restarted the car, and all problems went away (brake worked again, and battery light was off). After that it worked well the whole day. Can somebody please let me know what the problem would be? Any suggestions? Thank you in advance.
