regional tech from Hyundai repaired chronic check engine light problem, so technically not by the dealer. I had documented a formal complaint to Hyundai and it was the final attempt at repair before filing a lemon law complaint. There was no documentation of what was done but there were no further check engine light issues. The car runs fine. The dealers response was "it has a long warranty". Was all the previous work unnecessary; most likely.....
Car would not start under 7F. If sitting outside for more than several hours, the car will not start. All systems will turn on, such as fan blower, lights, radio, bluetooth, etc but car wouldn't click.
Car would not jump to start either. Had to be towed to dealer.
Dealer couldn't replicate issue unless car sat outside, then they claimed starter had bad spots in it and replaced starter. Car would not start AGAIN in temperatures under 7F. Same exact symptoms as last time. Brake pedal hard as well. The car had to be towed AGAIN to the dealership.
This time the inhibitor switch was replaced after dealership replicated the issue. Because the temperatures started to rise we do not actually know if this resolved the issue. We will find out this December or January 2020.

The parking brake would not release, initially. When it did, there was a crunch and ALL the warning sensors lit up. They remained that way for several minutes, even after driving away. About 10 days prior, the "Key Present" sensor lit up, suggesting that there was NO key in the vicinity. The car could be driven, but I clearly ran the risk of an on-road shutdown because no key was identified or activated.

The hybrid battery alert came on - it said "stop driving car" - looked this up online and other people have experienced it.

Fuel smell under the hood and inside when the car is stopped at the red light. Could smell it around the car after shutting engine off. 3 visits to the dealer (Richmond Hill Hyundai) said no problem, washed the engine, problem persists Fuel smell narrowed down to between ports 2 and 3. Pulled the intake - the groove for the intake gasket on port 3 is warped, gasket doesn't seal, thus a minor fuel leak. Replaced gasket, problem still persists. Pulled the intake again, applied Permatex gas-resistant high-temp silicone around the gasket. Fuel smell is almost gone, at acceptable level now - cannot smell it inside or outside. Ideally need to replace the intake - an $800 part.
