Car Won't Start - Electronics Going Haywire

34827 Views 14 Replies 13 Participants Last post by  Derekm27
Hey everyone,

When trying to start my car, it does not start, makes a clicking noise, and all the electronics are going haywire. Headlights, dash, interior lights rapidly flashing, sometimes it says the key isn't detected, sometimes it says refuel. When trying to unlock/lock the car, the mirrors aren't folding out and the lights rapidly flash.

Here's a video of a little of what's going on: Streamable Video

I checked the voltage on the battery and got around 12.53-57 so I don't think it's a voltage issue. Connections are clean and secure on the battery leads. The car was driven with no problems roughly 4 hours ago, so it is not an issue with it sitting for a long time.

Any idea what this could be?

When checking voltage, did you check the terminals themselves? If so, take a reading on the battery cable ends to see if there is any difference, then check between the positive terminal of the battery and an engine ground to see if 12+ volts.

Might also want to keep the tester on the battery and try and start the car to see if voltage drops drastically.

having the same issue, also seems my hood latch is stuck and i cant get the hood open on my '11 SX...hope someone is on and can help at least get the hood open
Does the hood pop open slightly when the cable is pulled? Had a problem with an '08, but the hood did pop uip slioghtly and had to work with the latch to get it opened.
Actually was a bad latch assembly and not the cable.

Same issue but autozone said the battery is good.. is it the same situation where its good on test but not enough to start car? Should I buy a battery?
Get a MM and check the battery voltage @ 12.6, make certain cables are clean/tight, then try and start the car to see if the voltage drops substantially.
Sound, numerous clicks, or just one everytime the key/button is turned/pushed?
