KIA Motors

This is the 4th time my wife an i have scheduled an appointment for the same issue and we were charged for the service on the 2015 KIA soul. the car is still under warranty and only has 43, 773 miles. the service department keeps giving the same excess regarding the rough idol at stop lights. the problem has not been solved and we were instructed to use a higher quality gas and change the filters on a regular basis which we have a n have had the check engine light come on 3 times after their ser vice which my wife paid for when the car was under warranty. i explained my issue with the finance manager Ricardo and he said he would get with the service manager. yes as expected no return calls so we made a 5th service appointment for Monday 1/13/2020. most of the problems started to occur after a recall for the catalytic converter recall service. we were told by the service department that there was a lot of carbon build up which was affecting the cars performance. we are tired of the excess and it's about time we get a lawyer and submit a complaint to report our service papers which leads us to the next step. i hope this issue gets fixed correctly because if not we will proceed to move forward. we have been patient with this service and not to mention the time we spend taking the car in.

I purchased a NEW KIA SOUL in 2015 from Perris, CA. Dealership.
I have 42, 931 miles on the car with full warranty which I'm paying for.
I would like service Department to take responsibility for charging me for the service and also for the incorrect diagnosis regarding Error Code P050A which the car came up with at the service dept, back on 11/06/2019. I replaced the cabin and engine air filters as instructed by Kia Service. The check engine came on 3 times and my husband who is a mechanic said he oulled up the same code as KIA and they need to check the Mass air control sensor. Which they finally repaired and know check engine light at this time 01/02/2020.
My complaint is all the service dept did was clear the engine codes on 11/06/2019 and fuel induction service to clean out carbon build up. I keep getting excusses to use a better octain gas. I should not have to worry about what gas I need to use and was not told this detail when I purchased the car. Which leaves me to believe I purchased a car that I can not use with out certain gas.
On 12/26/2019 I returned to service dept. and they replace the masss idle air control sensor. I do not have the check engine light coming on.
My question to whom it may concern is why I was charged for the first visit on 11/06/2019 for the amount of $164.80 when this is a WARRENTY ISSUE. I sure hope someone will repond to my complaint. Lets make this right.
