Last night I rode in my son's 2014 Patriot 2.4 liter awd automatic six speed on 230 miles of ice covered roads. Temperature 3 degrees Fahrenheit. Road salt was not melting the ice on the roads. Lee had to drive at less than 40 mph to stay in control. Load in car 900 lbs. We were passed by EVERYBODY including two Fiat Renegades - no stability problems and a Patriot that was obviously a 2wd going at least 65,
This vehicle has an engineering problem. The electronic transfer of power to the rear wheels is too sensitive. The same axel brake locking differential is also too sensitive. When the two are operating together on ice there is very little directional stability.
On the newer Compass and Renegades there is a dial on the console next to the gear shifter which can be used to adjust this twitchy overly sensitive traction control.
It is not tires, suspension, tie rods or any other suspension parts. It is an overly sensitive over reacting non adjustable inadequate traction control system...
If the road was as bad as you describe I don't think there is a vehicle out there that can handle 40MPH in snow or especially on ice. Seems to me your son was being prudent. Anybody doing 65 under those conditions is nuts. As for other vehicles passing you, I agree its amazing what some people get away with . . . and sadly, some don't.
Gosh, I sound like my Driver's Ed teacher!
Now presuming that you were driving in adverse conditions and unable to maintain a safe
reasonable speed, then most likely you have a tire problem -- maybe uneven tread or inflation, or maybe you were running on all-season tires. As I've said umpteen times on this side (and possibly earlier in this thread) all-season tires tires are not dedicated winter tires -- really they are three-season tires. Driving on ice is where you will most miss the quality rubber formulas that you need under severe winter conditions.
If you've read through these threads then you've seen some suggestions regarding possible culprits such as alignment. A minor problem that is undetectable on a dry road might be all the nudge your vehicle to be unstable on ice.
I drove home about an hour ago. According to my EVIC the temperature was 26F and my road, while treated, was still ice covered. I have AWD and studded tires and I still felt my Jeep slide a little. I wasn't surprised. Ice is what it is: no tire is magic, nor will any suspension or AWD system overcome it. You are piloting an awful lot of weight at a remarkable speed, all while you are at the mercy of a very little rubber on a surface that provides very little help.
I've spun cars around in winter driving and it wasn't the fault of the vehicle or the tires, nor in most situations even me, although in every case I admit I should have been going slower. I humbly admit to one time playing around in snow and doing a 180, but it was at a slow speed. I was trying to show off and make my car fishtail and when it did I overcorrected. Silly me; I was 16 -- need I say more?
Drive careful out there!
