NHTSA Complaint #11551423 — 2016 HYUNDAI SONATA

3 months after the engine was replaced under extended manufacturer warranty the vehicle started shifting funny, took it to the dealership and was told the transmission was bad, then another person in service said the transmission wasn't bad and didn't need to be replaced and they couldn't find anything wrong (after waiting for 2+ weeks for the transmission to come in), then the car left us stranded on the side of the road and not running, took it back to the dealership and was told it's a bad catalytic converter and we had to pay $2000+ to replace it. They at this time blamed the engine issues on a bad alternator. Now the car has a check engine light again and is throwing the code permanently for the catalytic converter. No way that a HYBRID car that barely ever actually runs on the engine should need a new calaytic converter around the 100,000 mile point except for an engine malfunction, which was the case and that engine was replaced back in December. Hyundai says it's not related and sorry, you have to pay for everything.
