I have an 09 Journey and have had multiple problems. Last week the tensioner pulley completely broke off. About $100 fix (pulley and new belt) but it seemed to be running fine again.
Yesterday while driving, I noticed the steering wheel shaking at about 50mph. When I got home there was a faint burnt rubber smell and light colored smoke coming from under the hood, near the cab on drivers side door. This was only after driving for about 45 minutes total. Entire time yesterday temp gage was right below halfway mark and no engine lights.
Oil was a bit low but no leaking from anywhere that I could see.
Not sure what this could be.
