You may have developed a short circuit or an electrical component failure that increased the load on the alternator thus reducing available engine power. Since the turn signals failed check that circuit and all other accessory circuits or accessories that are attached directly to the battery.

Why did my 2003 Hyundai Santa Fe sudden lost power while driving?

what happened when you tried jumping the car? sounds like it could be a bad ignition switch since only non-switched things work.

No turn signal loss of engine power

Hi Billy. Normally I would not even think too much about your signals and engine problem without some more info however, I know this is like apples and oranges. Guy couldn't keep his off road 4 wheeler running which has 'turn signals' on it too!? Don't ask me! Anyway, the thing would run as long as you didn't give it too much gas too fast. Lights dimmed when you did as well. What we found was that greenish colored corrosion that copper wires get where they are attached to a connector or pin before they're hooked up to whatever. My point is look for any corroded connections in the obvious places then look under the seat, the frame, anywhere there might be a plug connector and try to feel for loose connections. It can be a time consuming task but before you have parts changed and expensive mechanical troubleshooting done take the time you have and try looking for the obvious. We found a wire that had plastic wrap by the factory at a point where the wire branched into two. It looked questionable only because the wrap had begun to unravel. In the wrap was a wire that was exposed to the elements and had turned green and corroded. We were able to cut it back and reconnect it. The thing now pulls the front wheels off the ground. Hey, its just an idea that worked for us.Good luck and let the forum know how you make out. Donald Hosford

I was driving down the road and lost steering.

did it restart?
the engine stalled, as such you
no engine power
no P/S reverts to manual steering, you did not loose steering.
same with P/B power brakes, you didnt lose it you lost power
assist, brakes will stop just as vast but takes a husky foot.
in school (driving) we were though to drive, stalled engine.
i guess most school went dumb. (seen it)
now stalls
engine stall for a vast number or reasons.

do that tuneup not called the 60k mile service point list. did you.?
cars ignored all fail, no car runs 300k miles service free,
skip them and get stranded, (i promise)

1: lost electric power to the EFI system.
2: engine overheated or lost compression for any reasons (complex)
3: lost spark
4: lost fuel
5: too much fuel, flooding, and stalling.
6: egr sticks open.
7: ISC sticks closed.
8:if not restart, say so and list expands way more...

cars are complex, it's not like a burned out desk lamp.
vast complexity and after 2007 , insane complexity.
avoid them 2007 and newer, sans NASA engineer.

you may have an issue with your BCM (body control module) when it fails, it takes everything with it and pretty much makes the car a heavy paperweight. your BCM is the brain for the vehicle like the ECM is for the engine compartment

Sometimes while riding down the road the engine light will come on and the car will lose power.and die. I wil stop and turn the engine off and it will run ok again. Sometimes I have to do this twice before...

Your computer is picking up a bad signal from one of your engine sensors, when you turn off the car you are resetting the computer and will run ok, the thing to do is that your car some where like autozone where they can do a code reading for free, then get back with us here at FixYa so we can help you diag. your trouble code.

Sometimes when I put the turn signal on either left or right (doesn't matter) the car shuts off. Doesn't matter if I am driving down the road or sitting still. Just barely hitting the turn signal switch...

From what I've been told, the late 90s and up GM cars have the main steering column wiring harness bundled. It runs down the steering column, into the engine bay, and under the battery. Take a look at the area around the battery to see if it is leaking. If the battery is leaking, the fluid is both corrosive and conductive. If it leaks onto the harness, it may have eaten the wire jacketing on the harness wires. In that harness will be the wires for both your turn signals and your ignition switch. If they're shorted together, when you activate the turn signals, you may be killing the ignition.
