Sonata Hybrid 4D 2.5L

  • Automatic transmission
  • 53,100 miles

Just owned this 2012 Hyundai Sonata Hybrid for only... 2 weeks! It only has 53,100 miles. The car was making a lot of noise when I was driving on the beltway. Then it starts losing speed. I pulled to the side of the road and I noticed the battery was going low. The engine then stopped completely.

engine failure

I loved my Hyundai right up until it died on me while driving on I26 toward Columbia SC. $150 tow to the dealer in Columbia to learn I had engine failure. Given I had the oil changed at my dealer in Atlanta before leaving, this was a total shock. The service advisor lets me know this happens but there is a recall. Hyundai will take care of me. Only my car isn't covered by the recall. No problem, he says, I'll just put in a claim. Since you have the exact symptoms as the recall cars, we've had Hyundai fix them via a claim. Since I had 101053 miles and the warranty is up at 100k, Hyundai informs me I am denied. 😤I guess the saying is true- they love you til they don't.

The check engine light and the oil light never illuminated though, it appears, there was some major problems in my engine.
