CX-5 stalled at high speed

[jadmt]

Please Google how to turn off the radar part of the cruise control. I just found out you CAN turn it off and still have regular cruise control. Read my other recent post as it explains the procedure also. I am so happy someone pointed this out which caused to to Google it.

I turned mine off a long time ago as I hated it.

Good to know! How were you able to trace it to the plugs/coils? I'd be stumped after fuse/battery.

I've got this amazing troubleshooting tool, it's called YouTube

I might not be as lucky the next time something goes wrong.

Already went to the dealer...no help finding the possible problem.

Well how motivated are you with throwing darts in the dark?

I rented a Kia Niro EV for 5 weeks after my CX3 got rear-ended by an old Camry. I hated the way that EV kept braking for me and yanking the steering wheel. Turned those features off in a day or two. Haven't had to listen to anyone telling me how to drive for a long time.

This would be one of those cases where the car needs to be driven with a really good reader plugged into the odb port, so that a wide range of parameters can be monitored and checked in real time.

That will shown for example, if fuel pressure is maintained within specs at higher speeds under load.

So unless your dealer service department did that, they haven’t done sufficient testing and diagnosis.

Dealer didn't seem to want to find any thing that might cost them money. Already had them look at it. These car's have a history of fuel pump problems, so you could be onto something. I might have difficulty getting them to do any further diagnosis unless it's done legally. Waiting for a reply from a certified letter I sent to the general manager of the place. If he doesn't respond, I can pursue other options.

It isn't actually clear to me that his car stalled on the highway as the title states.

He says he didn't notice it was off until after he stopped. And he says it didn't take a lot of effort to stop or steer the car from the left lane to the right shoulder.

If you've ever tried to move the car with the engine off, you'll know that steering and braking are very hard--I can't imagine stopping this car without the power brakes from highway speed.

There's just no way that I would not notice that the engine wasn't running because of the other effects that it would have.

I hate to sound like I don't believe the OP, but I'm just going off what information we have. I truly hope the car is fine and safe to drive.
