Three problems related to battery have been reported for the 1998 Jeep Wrangler. The most recently reported issues are listed below.
My gauges on the dashboard consistently go to "0" while driving my 1998 Jeep Wrangler. My speedometer,tachometer, battery status, oil, and engine temp all go to the left and the red airbag light comes on. This especially occurs while driving over bumps. It is a huge safety concern because I never know how fast I am going, when I need gas, or if my air bag will deploy in my face or if it will deploy in the event of an accident. There have been so many other reports concerning this same issue that it is incumbent on the government or Jeep/Chrysler to rectify this situation!.
