Now the jeep is making a strange noise while driving.
Battery light in my '07 Jeep Grandcame on while I was driving. on 2007 Jeep Grand Cherokee
Have the electrical system checked. Most likely the alternator is bad.
If your battery light was on, the charging system needs to be check. Some times the alternator makes noise when is charging.
