My brake proportioning valve on my 2003 Kia Rio cracked. My mechanic says it should never crack no matter the temperature climate etc. He says he has never seen a cracked one before and my car would have no signs that it was bad. I would go from perfect brakes to no brakes. That is pretty much what happened. I was lucky and had just got gas and leaving the parking lot. The brakes went out while I driving slowly to the street. I had enough break to stop. My complaint is not for me so much as someone else who may not have been so lucky. I fear for others. Please check this out on further vehicles.

Aug. 12, 2006 the harrell-swatty cos. 6 concourse parkway ne atlanta ga 30328-6117 dear Mr. X: I am extremely disappointed in Kia at arbor place. I took my car in for warranty service in March because the brake light kept coming on. I brought it back three more times, but the problem has not been fixed. Now that the car has more than 60,000 miles on it, the department would not work on it again unless I paid them. But they took it in to diagnose it again and did not tell me until I came to pick up the car that it would cost me $88 diagnostic charge to get it back. The brakes completely failed once. I was fortunate there was no accident. I keep adding brake fluid when the light comes on. Evidently there is a leak in the brake system. The car is unsafe. I want my $88 back, and I want the car fixed, at no cost to me. Yy zz has not replied to my two previous letters.

In April 2003 I bought a 2003 Kia Rio cinco for my family. When I try to start it in the morning it will not start. It takes about six to ten tries to get it started. Then it runs bad for miles. It also runs very hot and it seems the more I drive it the less preformance I been geting. My brakes are also bad when I first drive it after it sits for hours. Kia told me that it all has to do with the reformuladed gas we use in milwaukee and Chicago. After months of people at Kia not calling me back and tring to resoulve this with Kia I am interested in a class astion law suit.

The lug nuts peeled of the passenger side front wheel. The tires were being rotated. When they were removed the lug nut(s) peeled off. The rear brakes were locking as well and caused the vehicle to skid sideways during the first mile or each morning.
