Service light came, called Genesis and they towed vehicle to the shop, offered me a rental but declined. Verdict was fuel pump control module needed replacing. They replaced the module, cylinder 8 injector, spark plugs and changed oil.
Car shakes very noticeably at idle. Vibration is much reduced when turning off the A/C system. Worst when stopped in gear, but reproducible caused by A/C system being on (compressor?)

Faulty oxygen sensor had car stalling and Traction Control engaging constantly. Reported the Traction Control button was constantly on issue to dealership, but they wouldn't diagnose it unless Check Engine light was on. Whn I brought the car in when the Check Engine light was on, was told I'd have to make an appt. WhenI brought it in for appt, light was off, they wouldn't diagnose it. Car finally died in their lot before they had to push it into Bay and then told me it would be 3 days to get sensor replaced because part had to come from Vancouver. Then told me that Rotors were warped and pads were shot; $1000 bill.

Took car in for Oil change, brought it home to find it was leaking slowly, leak turned into torrent, had to have the car towed back to the dealership at my cost despite my extended Hyundai Factory warranty includes Roadside Assistance, but dealership doesn't like recognizing it. They claimed issue was a corrupted Oil Pan plug. Drove car home, only to realize it was leaking even worse now, had it towed again, 3 days later they claimed it was extensive impact damage to the entire undercarriage and that I should file an Insurance claim to cover the "Thousands" the repair would cost. Took it to an independent garage, for $379 they replaced the Oil Pan, recognizing that it had the same type of plug as Toyota Corolla's which are apparently known for becoming corrupted. Could not be more disgusted with the incompetence and attempt to deceive and defraud

Car would not start when very cold. Engine would crank but no start. As if no fuel or no spark. Had the throttle body replaced under warranty. Front cover as well as oil pan leaking oil!

See above. Engine is turning over way too long before starting. Started after the spark plugs were replaced at 100,000 miles. The dealer did that work, and cannot explain the prolonged turnover after testing for two full days. Car always starts. The battery is fine. To be fair, I am presuming the problem started with the spark plug replacement, and I am associating the problem with that maintenance step, because it never happened before the maintenance, and has been happening from the time I first picked it up. It's been back to the dealer, and they have not identified the problem.
111000 mi
Car turning over too long was re evaluated by the dealer, but they feel it's the fuel pump now, and suggested that I live with the problem. The car always starts, but if the car did not have a glass mat battery I suspect the battery would have gone dead from how long the car has to turn over.
