One difficulty I see is that virtually everyone drives under what Kia calls "severe" conditions at some point, therefore everyone should be getting more frequent oil changes, yet the longer interval is presented as normal, misleading consumers to believe they can change their oil at 7500 miles rather than 3750 . . . until you have an engine problem and then are they going to say no, you should have been changing your oil every 3750 miles, we're not covering the repairs??
The longer oil change interval is supposed to be a benefit of using much more expensive synthetic oil. Why are we using such expensive oil if it needs to changed as often as regular oil? I feel like this is deceptive on Kia's part. "Normal" should mean "applies to most people." In this case it appears that "severe" driving conditions apply to most people. I think more than half of all drivers experience at least 7 of the 11 conditions called "severe":
1. Repeatedly driving short distance of less than 5 miles in normal temperature or less than 10 miles in freezing temperature.
2. Extensive low speed driving for long distances = traffic jam
3. Driving on rough, dusty, muddy, unpaved, graveled or salt-spread roads (More than half of states use salt)
4. Driving in areas using salt or other corrosive materials or in very cold weather.
5. Driving in heavy traffic area.
6. Driving on uphill, downhill, or mountain roads. Seriously? If we go uphill or downhill that's severe driving??
The terms should be changed to something like "light duty" and "normal."
I think this will come down to whether Kia is overall an honest company that cares about its customers, or a company that will deny valid claims on the pretext that almost everyone should have been doing more frequent oil changes.
This reminds me very much of the Subaru head gasket problem that went on for years and was very difficult for owners to correct properly. You had to do a ton of research to find out the serial numbers of the defective parts and avoid them when you got the repairs. And one Subaru service manager told me the problem continued long after Subaru claimed it had been fixed.
Very disappointing! The Kia Soul was my dream car!
