Alternator and brake light came on while driving

Asked by RT_Omaha Jan 25, 2016 at 12:16 PM about the 2007 Hyundai Entourage Limited FWD

Question type: Maintenance & Repair

Driving a 2007 Hyundai Entourage on a vacation trip, Had the battery replaced in Aurora CO, then in the drive back,m when speed was increased to 75 mph, the alternator and brake light came on and lost most of the power. I had the car checked again at a different location of the same car repair shop and they are telling me that all is sound, no issues found. Then again the issue just happened, any ideas?

The alternator light comes on to tell you there is a problem with the charging system, usually when it is not charging. You should have 14.5 volts at the battery when the alternator is working. As them what it is. The break light comes on when your break pedal gets low to the floor indicating a leak in the break system, or the E-brake is depressed some by accident. Pull the release for the E-brake, or if it is a lever in the center make sure it is all the way down.

And, if the alternator is fine, the battery is fine, the brake system is fine and not leaking anywhere, and the emergency brake is not depressed? What then, if it only happens when traveling above 75, or along with a sudden burst in acceleration or a sudden movement of the steering wheel?
