Asked by shughes4 Oct 25, 2013 at 01:30 PM about the Jeep Liberty

Question type: Maintenance & Repair

Complete loss of electrical power, as if a reboot happened; dash lights went off while driving as if the car had just come back on.  Then, the check engine light was on.

2 days prior i was rear ended basically with no external damage, a loose bumper and scuffed trailer hitch.  I did not drive it until the less than 2 mile drive down the road i lost electrical power while going down a flat road.

Sounds like ground connections were damaged...have your mechanic inspect the chassis ground connection from the car battery...take a gander at the battery itself to see if the connections are sound and not corroded~ and the GROUND 1/0 cable has enough area of contact to pull the requisite 300-500 amps~...but the chassis ground is the key...without it computers act weird "brown out" conditions occur and CEL comes on~....Maintain Ground Connections....will fix YA~

Tighten and clean all battery connections. Also tighten and clean negative connections on frame and motor.

corroded connections, especially ground connections can do this. did you mention what type and year of car this is?

Its a 2005 Jeep Liberty Renegade 2.7l A/T the battery didn't seem shifted or moved; but i'll take that under advisement. I don't think my luck is that high, but i'm hopeful.

That is a good possiblity, i will pass that on and see if the problem is that. My sister had said something about that as well, that it might be an ignition problem. If its just a relay that would be a blessing as well. I do not look forward to car expenses; especially when i have so much traveling planned that i cannot afford the delays.
