I venture to guess he's not driven MY CRD.
I have used an accelerometer/GPS device and measured my CRD at 7.8 seconds from 0-60. Go get your 2.4L 4-banger gasser, or bring your jacked up 3.7L to the drag strip and we'll see how they stack up against my CRD. I mean...after all, the CRD has no power, and it's slow, so let's make a nice wager on it. We can go double or nothing and run the race with a 2000lb trailer attached.
I've seen 30.1mpg on the highway.
I've seen 25mpg towing a 2000lb load (even over some mountains). The V6 Ford Explorer gasser I was traveling with returned 11mpg on the same trip.
I get 21mpg in heavy stop and go city traffic. My old Explorer got 14mpg. My PT Cruiser 5-speed...19mpg.
I've had NO engine issues with my CRD. Now, the crappy transmission (same one as the gasser Hemi pickup) is an absolute POS. It can't take the torque of the diesel. The gasser V-8 doesn't appear to be strong enough to give it any problems.
The 2.8L VM Motori diesel is used in marine and industrial applications. The 3.7 KJ motor is used in what else? Oh yeah. NOTHING. Would you trust your backup power, or your boat 200 miles off shore to a Chrysler 3.7L gasser. I wouldn't! Neither does anyone else.
The engine "problems" you see on this forum aren't really problems so much as they are preventive maintenance. I'm willing to bet the CRD would run hundreds of thousands of miles if you did nothing to it but change the oil regularly. You might have an EGR issue (which is common on all diesels that have them, not just the CRD), but gassers have EGRs too. Diesel owners tend to be enthusiasts. The want peak performance from their engines. I bet if you went to any sports car oriented forum, you'd find the same discussions going on. You also see a LOT of people here abusing the CRD and using it for things it was never designed for, like towing travel trailers and such. Chrysler designed the Liberty for Suzi Soccer Mom to tote the kids around in, not to pull travel trailers....yet, the CRD engine keeps on chugging, despite what people do to it.
A friend of mine has an F150 V8 pickup, and he used my Jeep to tow his trailer while his truck was getting some work done. He commented how much better the diesel pulled than his gasser. A 4.6L V8 outpulled by a 2.8L 4 cylinder. Yeah....the CRD small diesel is a real POS all right. I guess I should put it up for sale and go by a gasser. I'm convinced.
