Won't start in negative temps

[juliehrdlicka]

We have had -30 temps in the Midwest the last few days. My 2019 expedition hasn't started since Sunday as a result. I replaced the battery because it tested out as dead. I installed and all the electrical comes up, but I do the push button start the engine doesn't turn over, just makes a clicking sound. I can't even push the brake pedal down. On the dash the engine light and battery lights are lit and I get an error saying 'check brake system.' I'm waiting for roadside to tow it to a dealership but any ideas?

Do you do a lot of stop and go driving with the auto stop/start turning off the motor at stoplights or stop signs?

That really sucks, of course, but I would just wait until everything thaws out, recharge the battery and try it again. That's all the dealer is going to do, and charge you for the towing and labor.

Actually, your money would be better spent on a jump start pack like this, https://no.co/gb40 You'd be able to crank your motor in a matter of seconds without needing help from another vehicle for a jump.

A clicking sound on try to start is the symptom of a low 12V battery. Don't worry about the brake pedal being hard, you only have to barely move it to actuate the switch allowing start. When you press the brake pedal, look for the green LED in the start button. That tells you the brake pedal is depressed enough.

I do mostly local driving but I actually don't deploy the stop/start function often. I did put a new battery in so it shouldn't be a battery issue anymore. Brake Fluid is full, i checked that. I have a tow scheduled but I'm just realizing it won't go into neutral so I don't know what to do.

-30 is the lower end of the typical limit these things are designed for. If your evenings are around -15/-20 for more than 2-3 consecutive days I would recommend engine block heater. The trucks will work at these temps but not without some pre-planning.

I have seen the bendix drive hang up frpm the cold. If youcan reach the starter hit it with a hammer. Maybe go thru the wheel well with a rod or pipe to extend your reach. frost gets on the bendix shaft and locks it up

Here's the procedure to put the Expedition into Neutral when there's a no-start condition.

Edit: Just re-read that your engine won't turn over. Tow guy should have dollys for the rear wheels.

Start/Stop has nothing to do with this issue, and have no idea why that was even brought up.

@rd618 and @Retiredusps made excellent points, you are at the temps where a block heater would be beneficial, and it could definitely be a stuck starter.

Also, you made one significant assumption, that the new battery has a good charge. If it has been sitting on a shelf, it most likely does not. I would put it on a charger, or use a jump starter to get it to crank. Disconnect it from the cables, and put a volt meter on it. What is the Voltage? I would put money on it that the battery is low off the shelf. It needs a charge or simply some assistance from a set of jumper cables or a jump box.

Excellent info @Fizzy!

Did you use a block heater? That is extremely cold.
