Other than normal wear and tear (which is slight). There were two small problems around 100000 miles. For one, the exhaust system failed. The vehicle needed to have the exhaust system replaced. Which included the catalytic converter, muffler, and tailpipe. Secondly, the vacuum switch also failed.
The jeep Rio Grande is a very reliable vehicle. Of course there will come a time when it will need a little care. That is not a problem with the Jeep Rio Grande. It has got to be the easiest vehicle to work on, especially for the do-it-yourselfer. You will not need to hoist or jack up the vehicle to change oil, or do most underbody repairs because of the exceptional ground clearance. On the road the Rio Grande Does have a rougher feel than most are used to. It does not by any means, offer a smooth ride. But that is what sets it apart from the "soccer mom" sport utility vehicles. The peppy 2.5 engine does well in the gas mileage department. The Rio Grande also handles highway speeds very well. Off the road the Rio Grande shines. Remember Jeep is a recognized off road icon. Right out of the box you are good to go! However if you want to really shine offroad, you should probably get a Suspension lift. Large enough to at least fit 31-10.5-15 sized tires. Add sway bar disconnects to the package and you are an off road pro. The list of upgrades could go on and on. The few mentioned are more than enough to make your off roading experience more enjoyable. All in all the Rio Grande is a tank. It will take anything you can throw at it. I highly recommend this vehicle to anyone who is considering a Rio Grande. Whether you are a father buying one for his son or daughters first car, daily driver, or a toy you will not be dissatisfied. Find out what your missing. Buy a Jeep. Join the legend. Get the wave.
I currently own a 95' Jeep Wrangler Rio Grande, it is an awesome suv. but if you want to do some real offroading I suggest doing one better than a set of 31 m/t's.
My jeep has 31x10.5 15 tires and they do impressive, but unless you have a winch you need some meat on your rims I would say to do about a 3 inch body lift and a 2 or 3 inch suspension lift and put some 35x12's it might be a little expensive, but giving a little will give you a lot back.
I own a 95' Rio Grande and I swapped out the stock engine with a Chevy 350 out of a 88' truck. It runs very well with the suspension lift and the 5 speed manual transmission. I highly recommend this jeep for anybody looking to tare up some dirt. I also agree that the 35 tires bring much more happiness. Enjoy.
