Does anyone else have this problem? I installed a Drawtite trailer hitch (because I didn't want to pay for an overpriced Mopar hitch). The hitch installed with no problems. But immediately after install here's what started happening. After about 10 minutes into a drive on the freeway, there's engine sound coming from the rear of the vehicle-sounds like when a car has a bad muffler. So I realized that the muffler and tailpipe were rubbing against the back of the hitch. It happens on the freeway at 70mh or over when accellerating. But sometimes at 60mph or more. So I took it in to a hitch shop and they bent the bars forward that hold the muffler to the frame so that the muffler is further away from the rear of the car. This worked for a week or so but now it's back. I'm about to take it to them again to have them move it further away from the rear. Seems like a manufactures defect-putting the muffler so close to the back that you can't put a hitch on it without this happening. The muffler also seems very big in comparison to other Jeeps.
Certainly I'm not the only one who has installed a hitch and had this problem.
I still think that it's a flaw in the design of the car. I mean, a good aftermarket hitch should fit without problems and I haven't heard of any issues with this same hitch and same part number on a Compass.
Anyway, the bottom line is this. It's true, the OEM (Mopar) is the only one that I know of that works. So, if there are any Patriot owners out there that want a hitch, don't waste your time with an aftermarket hitch. You have to get the Mopar. It's not as expensive as I was originally quoted from the salesperson at the dealership when I bought the car-go figure. It is $189. plus $75 labor. (This doen't include wiring) But If you're using it only for a bike rack, you don't need that.
That's interesting. Maybe it's something about my Patriot. The dealership didn't say anything about it though. And as soon as the Mopar was put on the problem stopped. There is a big difference in clearance with the Mopar.
Yes, the bumper has to be cut for the mopar. It comes with directions and a template but I decided to let the service department do the install. I didn't want to take the chance of screwing up my new Patriot.
I Just installed the same hitch, and at speed I got the same rumbling noise. I checked and the plastic cowling/bumper rests on (or very near)the flat section of the hitch assembly. I jammed a 2inch square of plastic foam packing 1/2 inch thick (with goop on the hitch side) between the hitch assembly and the plastic cowling. Problem solved
Just finished installing a modified factory hitch ... it sits up real nice and tight out of the way... and yes you do have to cut the bumper .. following the template...
The modification is we cut out the dinky little receiver (1 1/4") and replaced it with a 2" receiver... set it to where it is no higher than the factory .. so only the receiver hangs about an inch lower ...
Not really planning on towing anything ... just using it for bike rack and the carry basket and also for the picnic table that goes in the receiver ... everything for all the vehicles is 2" no need for an adapter now...
Also it does give at least some option for a recover point if'n it ends up in a ditch ...
Veni... Vidi... Vici....TOGA!!!!!!

Hmmm...I'm considering having a Mopar hitch installed as well but if they have to cut the bumper, I might as well have the Park Assist added. And hell, since I'm there, might as well have a rear-view camera installed. Any ideas as to how much this will cost? Sorry if this is beginning to go off topic.
I had interference between the right end of the hitch and the tailpipe. Ground away about 5/16 on the hitch, painted it and no more noise. It seems like the flexible exhaust hanger softened when it was hot, and that's when the noise was loudest. My 2'' Hidden hitch fit without cutting the bumper or making the frame holes larger. It doesn't hang lower than the muffler either.
