NHTSA Complaint #11494911 — 2015 KIA SEDONA

My car a kia sedona, 2015, 85000 miles, was inspected by Matthews Kia on 10/7. It was RECOMMENDED that I have spark plugs and coils replaced. I was NOT told of the consequences or the urgency of this repair if I declined this repair. The check engine light was not on and it was running fine! THEY LET ME DRIVE IT HOME WITHOUT ANY WARNINGS. I went to bring it to a mechanic on 11/8 to have a second opinion and have the work done if they agreed with the diagnosis. That is when I was told it was a blown head gasket and the mechanic said there was nothing I did to cause this, I was able to drive it home, but i drove it directly to the dealership. They are supposed to last the lifetime of the car. It is only when I drove it 1 MILE from that mechanic to kia when it started to overheat, and The check engine light came on. When Kia inspected it and confirmed it was a blown head gasket and quoted me for a new engine. My safety was at risk because I have 2 children and when the engine went that is when the engine light came on and we almost got into an accident because I lost power.
