Check engine light came on at 12000 miles.
I like the comfort and overall design of my Ranger.
It gives no trouble pulling 1800lbs. of trailer and ATV's 36 miles one way. I have also put almost a ton of egg rock in the back and hauled it home. I do not recommend anyone do this that lacks driving experience. I could only drive 35 mph with this load, but my truck never let me down. However it did make me nervous.
The one complaint is the complete lack of throttle response from a dead stop with the a/c on.
Overall this is a good looking and tough truck. Can't really complain.
Congratulations on a really great small truck. I have owned 4 Rangers and none ever had one single problem. They are the toughest small trucks built.
As for power, I added a K&N high-flow filter, a Flowmaster muffler and changed to synthetic oil in my 2006 3.0 Ranger Sport automatic. This seemed to help. After break-in and those changes mine would smoke the tires taking off, while it would not even chirp them when new.
I never hauled anything heavy in my Sport, although I did haul a few VERY heavy loads of granite stone in my old XLT. Yes, it WAS tricky. The rear tires were squished down, and I have no idea how much weigh was in it. The front tires had a very tenous grip on the road, and maintaining 70mph for the 40 miles of freeway travel was a little scary.
