A few weeks ago my Jeep’s (2017 Rubicon) dash lights started flashing and beeping off and on while driving in the city. Very random, and the entire dash, including the stereo, even shut down completely and restarted like a computer would while driving. This did not affect the engine. Then, after about a handful of times I decided to pull over (dash lights were acting up again) to turn off the Jeep and start it up again to get the lights to stop flashing but the Jeep would not turn back on, it wouldn’t even turn when turning the key….NOTHING happened. I had to sit for a while before it would start up again. After this occurrence it started doing this more often, stranding me where ever I am, it would randomly not start.
I had a friend with a small computer read the dash and he said he saw spikes of voltage leading him to believe it’s the alternator, but he said he couldn’t be 100% sure unless he catches the Jeep acting up while the computer is attached. I called the Jeep service department and they said the same. The problem here is that it could take hours for the Jeep to act up so they can get a reading at $160 an hour. 😳😫
Questions:
1. Has anyone else experienced this?
2. If I replace the alternator, the Jeep original parts are quite a bit more expensive, can anyone recommend a less expensive alternator that will not go bad in a short time?

Your battery might be dying. I had this same thing happen and a simple new battery fixed it. My Jeep died right on the highway too, it was scary.

I highly suggest you stick with OEM parts or better. Even a rebuilt OEM alternator is better than stuff like Dorman.
