2012 Hyundai Sonata Owner Comments

problem #2

Jul 302017

Sonata GLS 2.0L

  • Automatic transmission

Light knocking under load quickly increased to loud knocking and loss of power. As the car is now outside of the extended 120K warranty, I now have a pile of scrap metal. Unfortunate part is that the car is just about to be paid off and otherwise in very good condition. I will visit the dealer today to see if any help is available or if I should just write off this company as one to avoid. Resale for Hyundai is going to tank soon. Get rid of yours now before it happens to you!

problem #1

Sonata GLS 4 cyl

  • Automatic transmission
  • 65,236 miles

Couple of months a go I'd noticed that the engine had an unusual sound. Whenever the engine shifts to a lower gear the engine sounded like a diesel engine (I don't really know how to describe it, those who ever heard a small truck with a diesel engine may know what I'm talking about) had like a rough sound, I believe. I took to the shop and the mechanic told me it may be that I had to recalibrate the valves. I don't know what exactly he meant with that, but he told me I could still drive the car, it wasn't that big of a deal.

Does anyone knows what I'm talking about or have and idea? Please help. Thank you.
