I scheduled an appointment for 8:00 am Saturday morning on 11/28/14, and told them my vehicle was leaking oil. I dropped it off the night before. They didn't look at it until Saturday afternoon, shortly before closing & told me I'd have to come get it & bring it back Monday because they didn't have time to fix it. The timing chain cover was leaking.

They removed the timing chain cover & oil pan, cleaned them both & resealed. May 15, 2015, I took it back in for another oil leak. They replaced the oil gasket. A week later I took it back for oil leaking & three other issues. They gave me a loaner vehicle & had my vehicle for a week. They said it was residual oil dripping from not being properly cleaned the week before. It took a week for that diagnosis because the other issues weren't resolved either!

June16th, my Sorento is back at the dealership because it's still leaking & repeat of two of the other issues. Today is June 25th, they still have my vehicle. They dropped the engine & said it is leaking where the engine connects to the exhaust manifold & they had to reseal (again) the timing chain cover. They've yet to even start looking at the other problems.

Main seal began leaking between 66000 - 69,xxx miles. Quart lost in 100 miles. Could not get into KIA dealer for diagnosis/repair for at least 1 1/2 weeks, so took to local authorized mechanic to perform work, which was under our 3rd party extended warranty we purchase (thankfully...as bill was approx. $1800) We purchase a year old, so did not fall under KIA transmission warranty of 10/100000.

While we do drive a lot of miles as this is our primary car for work and everything else, it is 90% highway/interstate and we change oil religously based on KIA recommendation (actually every 2 months/4000 miles)

Not only issue...quality on the Sorento we have is showing to be very poor.
