I have a 2015 Kia Optima with 24,300 miles I purchase my car brand new from southwest Kia. I took my car in for service because I had just recently had oil change at walmart 700 miles later my oil light started appearing. I took it to Kia because recently having oil change and car was no longer registering oil. Kia went on to tell very little oil was in my car I informed them that I had just had oil changed 700 miles ago. So from there dealership did oil change. I was back at the dealership week later with same issue. Service stated that he found sludge and I stated that I have held up my end of the deal with oil changes as well as I provided my receipt or oil changes. Dealership is not willing to hold up there 100,000 power train warranty stating that I was not getting oil changed in a timely manner which is bs. I have been researching and I found other 2015 Kia Optima owner were having the same issue as I am having with car excessive oil usage, oil sludge and engine problems as I am. I have been in contact with Kia consumer dept for help. I have also been in contact with channel 11 and channel 4 consumer justice dept. I have attached copies of other owners with the same issue. You we work hard to pay for and to have a reliable transportation for the dealership not to hold up there end of the deal. I believe that Kia is aware of these issues and neglecting to help the buyers who have purchase these cars. It's strange that I found ten other 2015 Kia Optima owners with exact same issue. 2014 models have already had a recall I think 2015 model should be included to the recall. I have attached other Kia owners complaints and issues with this model car.

Takata recall: The tire low light on he dash is always on no matter what I do. I have always had my tires changed from the dealer never from a third party. This is inconvenient for me because this is the identification for a low tire. So anytime I suspect a low tire I have to stop my vehicle where ever I may be get out and walk around the vehicle to manually test the pressure in my vehicles tires..

When I am driving my 2010 Kia Optima and go to slow down at 20 mph (only at 20 mph and only when slowing down) my car does a jerk or lurching motion, with a hard down shift to 1st gear.this happens no matter where im driving. From what ive been told theres a transmission update software which when updated. After being updated the dealer has to rset/lear the relearn procedure. Both steps must be done to eliminate the lurching/jerking. I feel there should be a recall for this problem.
