2 Differential Unit problem of the 2002 Kia Motor Sportage

Failure Date: 06/22/2006

I started taking my 2002 kia Sportage to the dealer and it had a clunking sound in the back. I took it in and the technician said he thought it was the muffler and it was loose so he kicked it with his foot and sent me on my way. I got a new muffler and it still made the noise so I took it to a local shop and it was the differential failure. It ended up costing me over 2500. I had to have a new differential put in and it every once in awhile makes a clunking noise when you put the transmission in gear. If the tech would have made the right decision it would have been covered by warranty. I have owned several cars in my life and never had this happen to any of them. I feel like the kia people should reimburse me for my time and money!!!.

3 Differential Unit problem of the 2002 Kia Motor Sportage

Failure Date: 06/15/2006

Noticed a small high pitched whine toward the rear of the vehicle. My mechanic checked and said that it was probably a pinion bearing in the differential going bad and should be covered by the warranty. Took the car to the dealer for a determination and was told that the differential needed replaced and was not covered under the warranty since the fluid had not been changed every 20000 miles along with a bill for $126. 00. Was not about to pay them the $1000 they wanted to replace a differential that should have been covered under warranty. Still driving the car which now makes a loud grinding sound and draws alot of attention which allows me to discourage any kia purchases from prospective buyers. The 4 wheel drive has quit working also leaving only single wheel drive making the vehicle very unstable on wet road conditions.
