2013 Hyundai Tucson Limited 4dr SUV AWD (2.4L 4cyl 6A)
I bought my Tucson in November 2013, a month after I had purchased it my problem started...I had not even reached my first oil change and my check engine light was on! I took it to the dealership I bought it from and
they hooked it up to their fancy computer and diagnosed the check engine light had came on due to a cylinder misfire. They told me that they would have to do a computer update and that would fix the problem.
Long story short I have been back to the dealership on average once a week for the same check engine light to be turned off. I have had a total of 4 computer updates, they have changed my spark plugs and coils two times and I still have the issue! It's been 9 month now!
