My 2018 JL sports brakes and steering failed today(AGAIN) causing a crash

Agreed, motor failure is reasonable and a driver should be expected to recognize the issue and react appropriately in the situation.

Even if the engine stalled there would still be residual power braking on the initial pedal input.

the onboard computer is constantly storing data. If you feel the engine died, there is a data trail to back you up. Just a word of caution—if you want to pursue a legal case, understand that the pre-crash data is stored including your speed. Not accusing, just saying the computer is a tattletale.

I'm gonna get up to 55 tomorrow and shut it down and test brakes and steering, just for kicks.
Not in traffic of course.

Yes, and every airline pilot should recognize runaway pitch trim and shut off the trim motors.

is this the same steering that’s in the dodge challengers? My sister lost power steering in hers, she had to have it towed. Even the AAA guy could only steer it a few inches very slowly with great effort. No way anybody could steer it quickly in just a few seconds to avoid an accident. I think it was a 2015 Challenger.

I was way off, it was a 2013 Challenger. When she had it towed to the dealer they told her it was electric steering.

.... i also lost ALL steering. I could move the wheel, but nothing happened to the direction of the jeep.

I don’t think the OP lost power asstance to the steering. He says that he could ‘move the wheel’.

And even highly trained people make mistakes in stressful situations and form false memories of the event. Only the computer will tell the truth if it is programed to capture the right inputs.

So i went out this morning, run up to 55 and shut her off. No issues whatsoever. Steered fine , stopped decent. So im saying it wasnt loss of engine.

This guy right here. If I could add a flair to your name it would be “test pilot”. Thanks for your service.

I did test it, too, but it wasn’t at 55—more like 5.

AFAIK you should be able to get an assisted pump or two out of the brakes (with the engine off) before the pedal gets hard. Unless you have a brake line leak or something.

Most likely scenario - this is a story to get everyone all riled up.
Seems like it worked.
I'll keep my jeep thank you.

Brake Failure and Steering failure have nothing in common. Sorry, you can loose steering assist but can still steer. You can lose a brake booster but still stop. This is true of all modern vehicles. There is no way you lost the ability to brake and steer, it is not possible.

I second this reply having spent 20 years as a technician and service advisor for a few high-end dealerships your steering does not just go out like that and come back. If it goes out it stays out. You have a gearbox on there not a rack and Pinion not drive by wire. If your power steering goes out you can still manually steer. This incident sounds more like you hit a patch of ice or hydroplaned. That is the only thing in this universe that will cause you to lose brakes and steering at the same time. As for the dealership telling you it’s a one time thing… Basically they couldn’t find anything wrong with your vehicle at all so they were just trying to tell you something that would calm you down. Or as we call it... NPF. Since I am also a licensed auto insurance agent… I feel safe to say you were probably considered at fault in the accident in which even if you come up with undeniable proof that the manufacturer was at fault somehow That will not change a thing as far as the insurance goes.

I think it's similar. Must be something about the EPHS system. We had an older 300 where the engine died and I was able to turn it when getting it pushed in the street. It definitely required a LOT of effort lol.

No it is not the same steering system at all the Dodge Challenger has a rack and Pinion steering which is completely different

Here’s the thing… They clearly stated that they turned the wheel but it did not change the direction of the vehicle. So that would mean the entire gearbox had to fail momentarily. I don’t know how much experience most of you out there have But that just doesn’t happen!!! I would say borderline physical impossibility.

You're thinking troll? Hmm... maybe OP should post some pics of crunched front end?
