Car - what if engine suddenly quits

[LouNY]

Yes, the previous picture of a work vehicle is a much better vehicle then the Yuppie thing in the last pic.

The drop sides is one of the features that I really liked about utes. It makes it so easy to load and unload. However, that feature alone in many US states bumps the vehicle from "automobile/personal" to "commercial" licensing.

Yep and makes any attempt at import subject to chicken tax

Having worked all my life in the auto repair business, I have lots of experience driving dead, or partially dead vehicles into the shop. If they don't run, usually they are pushed by hand, sometimes by another vehicle.

Vehicles are all designed to be controllable, when the engine fails while driving.

As the speed decreases, you will be required to use more effort steering. Making turns will be very difficult at lower speeds. The sharper the turn, the more momentum it will take. Plan carefully.

You can gain some distance by putting the transmission in neutral as soon as you realize the engine failed. A mechanical shifter on an automatic transmission, will always simply move into neutral if you just push it in that direction.

As stated, the brakes will depend on how much vacuum you have left. When that's lost, they will still work. just not effectively at speed.

Many people don't expect to have to use so much effort to steer and stop, so they mistakenly think it's not possible, and give up.

Find a big parking lot, and turn the engine off while moving, to see what happens. (This should be part of driver education training).

If you have a key ignition, make sure you don't turn it all the way to the key removal position especially on a really pricy car from luxury car rental. That will lock the steering wheel.

One tip I’d add when steering without power: use your body weight to help turn the wheel. If you're at a dead stop or moving very slowly, it’s almost like wrestling the wheel, so leaning into it makes a big difference. For braking, you nailed it—people panic when they lose power assist, but with steady pressure, you can still stop the car. It just feels very different. Also, the point about shifting into neutral is critical. I’ve seen so many people freeze up or forget that they can coast in neutral after a stall. It’s one of those skills you only realize you need when you’re in a bad spot, so practicing it is a fantastic idea. I agree that every driver should know how their car behaves when the engine cuts out, but so few ever try it in a controlled environment.

Some new cars have electric steering, wonder how that works in a power out situation.
I'm not willing to try and figure it out in my wife's car though.

I had a car runaway on me years ago. It was a Pontiac Grand Am and I felt the cruise control did it. I instinctively put it in neutral and pulled in a parking lot and shut it off. It was bumping up and down against the rev limiter.

I remember a story years ago about a woman that had this happen and her transmission mount broke and it wouldn’t go into neutral. She could have shut it off with the key but they think she was turning it the wrong way. She called 911 and the police got in front of her and somehow got her slowed down and stopped.

Some cars do indeed have steer by wire, Mercedes comes to mind, and there is no direct connection of the steering wheel to the front wheels. This means that if the electronic steering fails there will be no way to steer the vehicle. Apparently this steer by wire is more reliable than any mechanical steering setup. This is based on the rate of total failures of mechanical steering systems versus total failure of steer by wire systems. I'm dubious, but what do I know. It seems to me that it would be best to incorporate the best of both systems. Use a direct connection from the steering wheel to a steering mechanism and incorporate an electric assist. But what do I know, I'm just a steering Luddite.

Reminiscent of the old Ford Rancheros and Chevy El Caminos.

Can you do that with a modern vehicle that has pushbutton start? I didn't think the engine would turn off unless it was in park.

No, you cannot turn off the motor unless it is in park, and that's a serious safety problem.

You can’t get out? One of my vehicles has the fob you just have to have it with you. You don’t get locked in, you just lift the inside door handle and it unlocks and opens.

Without the fob, you can't open the doors on my 2014 CTS-V from the inside unless you reach for the emergency cable located in the inside of the door sill beside your foot. Not a lot of room to move down there. Both doors have electric switches inside and out for the doors.

I think that is model dependent. On mine, you can't turn the vehicle off while moving, but you can do it while stopped, foot on brake, and not in Park.

@eptm I share your concerns about steer by wire. AFAIK, the enhanced safety of steer by wire is through redundancy and the lack of a mechanical column in a crash. Your comment prompted me to look for data, and as far as I can tell there isn't data, in part because so few vehicles have been sold with only steer by wire.
