Just purchased Sorento and within a week a p1326 code came up. Kia refused to look at car saying they are booked out for months hung up phone on me.got the same response from every Kia dealer. Had a mechanic replace knock sensor and the problem still exists and car not drivable. I’m a single mom with two infants and spent all my money buying this car. I did a Google search on this car about it’s dependability and it came back very dependable with engines lasting upwards of 300,000 miles. Mechanic told me Kia needs to replace engine as it falls under class action and lifetime warranty. Kia will not schedule an appointment for me to bring car in. Why are they not pulling these cars off road knowing they are damaged and continue stealing people’s money ? This is destroying me and my family I may lose my job over this and I’ll lose my apartment. Again I’m a single mom and can’t afford to be defrauded like this. These vehicles should have their titles branded if Kia not going to repair them.
