Traction Control ??

Deadman · Jan 31, 2023

Gosh I wish mine was less invasive. In any snow, the damn traction control cuts ALL the power and then the retarded trans thinks it should shift up 2 gears. Then the TC gives me back the throttle and now its 2-3 gears too high and takes a few seconds to shift back down into a reasonable gear, and THEN we can finally start moving forward again. Its ridiculous. I wish it wasn't there, and its too much BS to fiddle with to shut it all off every time I restart the car.....

Are you in a 4x4 mode? I've never experienced a wheel slip or TC activation when in 4x4.

Sometimes yes, sometimes no. Its annoying when there is just a little batch of ice by an intersection and I'm in 2wd and it slips and kills all power. I keep 4A off when I don't expect to need it as it wears the front end out by spinning everything for no reason.

OP here and update: We just had ice/snow in Texas and I was able to play around with the TC and 4A.

1. I think the TC is different in this car as it doesn't jump/jerk, it simply lowers power drastically but it's smooth feeling and causes me to believe it's not working.
2. 4A worked very good in the ice/snow
3. Michelin CrossClimate tires are awesome in this weather!

So today’s vehicles get stability control systems tied to what drivers often call traction control. Each vehicle gets a level of tolerance for traction loss based on the design of the vehicle ie the vehicle stability envelope.

If your prior vehicle was older and / or had reduced stability you would definitely notice the “traction control” systems being more aggressive regarding chopping power to prevent an uncontrolled skid.

I have noticed that the Expedition nanny is far less aggressive than my Toyota Sequoia. Thats going to have many reasons including the inherent stability designed into the Expedition
.
Also super aggressive nannies that cut power at the slightest loss of traction can cause serious performance issues and definitely trigger angry owners
.

My Sequoia occasionally would totally cut power to zero on right hand turns in the right conditions ie up hill street it would bring you to a dead stop mid turn. Well known gripe with the Sequoia owners

Tire’s definitely make s huge difference. The oem tires were terrible at 15,000 miles I couldn’t take the constant sliding anymore even wet pavement they were traction challenged. BFG trail Terrain new 3peak a/t tire for SUVs. Massive difference not even comparable 2whl with these tires can get thru snow that 4whl struggled with.
