I've done a lot of driving in the snow/slick roads over the years. I do not drive the Coupe in the snow. Not sure how that traction control (or the summer time only tires) would do, so it stays in the garage when the roads are bad.
What I've seen is that cars/trucks with automatics end up in the ditch on a curve/uphill/downhill situation.
The automatic changes gears, the engine rpm goes up, the torque output takes a big jump, the tires break traction, the driver may/may not hit the brakes, the brakes lock up and into the ditch it goes. Yes, all the new driver aids (traction control, antilock brakes, etc.) should help, but I'm sort of old fashioned. I can do it with the manual transmission and the clutch/gas pedal.
Computers are great - till the fuzz on you. I just spent an evening (two nights ago) fighting with this laptop. It was working great, then it wasn't. Locking up, running slow. Restarted it. No help. Tried to turn it off again and it would not turn off. Screen went gray, then went black, hard drive was really humming. Still would not turn off. Finally just pressed the button down and held it and it shut down. Then restarted it. No help. Came up really slow and locked up again. Shut it down, with the button, again. Waited several minutes. Turned it on. Went through a real slow start up and then it was working normally again.
Car computers can fuzz out on you, too. I stopped by the bank one morning, did some business and left. Hit the gas to cross a couple lanes of traffic and then let off the gas to coast up to the stop light. Started to turn right and head down the four lane and the car would do almost 5 mph. That was it. I turned right at the next intersection and into a parking lot and called the Hyundai service number. They sent a roll back out, picked the car up, took it and me to the dealer. About 30 minutes later they brought me the keys. The computer had run into some conflicting issue and shut down to put it in "limp home mode". Really, 5 mph is limp home mode?? It'll get you off the highway but home?? Anyway, they reprogrammed the computer and it was good to go. Not reprogrammed as in reloading the original program, but as in a new/updated program.
Had the computer in my IROC Z28 go south a few years ago. Started it up one morning to go to work and it was hard to start (it is never hard to start - one of the earlier models with the extra injector to aid starting and the MAF to read actual airflow instead of the computerized tables to calculate air flow). Then it started back firing/running rough as I pulled out on the road down the street from the house. No SES light?? That was crazy. No power, misfiring, stumbling, etc. and no SES? Turned around and came home (died a few times but would restart). Did a lot of trouble shooting (the simple stuff that used to work on the older cars) and finally replaced the computer and it was 100% again. The computer just went bad.
My nephews 2017 Silverado has had the computer replaced already. It went south on him after about 6 months.
Stuff happens. The more complicated something is, the more opportunity it has for failures, large or small.
Last but not least, I can/have replaced clutches/pressure plates and rebuilt manual transmissions. I wouldn't attempt to rebuild one of these new 8 or 10 speed automatics.
No real need/plans to drive it till the next trip home to the mountains so no need to get impatient waiting on the new tires/installation.
I just remembered, I haven't tried something since the reprogramming.
With the original program (this is a funny computer thing) the car will not spin the tires with the steering wheel straight or turned to the right. The wheels start to spin, then traction control/computer kicks in and stops the spin and you slowly accelerate (unless you let up on the gas to line up pedal with the speed). However, if the steering wheel is turned to the left it will burn the back tires across two lanes of traffic at least - done that twice while waiting on the traction control to kick in and do it's stuff. So, traction control works - unless the steering wheel is turned to the left. Computers. Programs. Never know what you'll end up with.
