Tl-the contact owns a 2015 Hyundai Sonata. The contact stated that the fuel cover to her fuel tank would not open from pressing a button inside her vehicle. The emergerncy lever to open the fuel cover in the truck of the vehicle would also not work . The dealer ourisman Hyundai of bowie 2404 crain hwy, bowie, MD 20716 (866) 295-4674 had to pry the fuel cover off in order to get it opened. The dealer however could not fix the cover so it could close again properly. They stated that there was a button that fell off inside the opener that was causing the issue. The cover now does not open and the contact has to the cover the opening of the fuel tank with a piece of tape. The maufacturer had not been conbtacted yet. The failure mileage was 89,000. Tf.

The gas tank lever goes down as if I were sipping on the gasoline. This has been going on since I purchased the used vehicle around June or July 2018.

1) gas tank never takes more than 15 gallons of gas when the gas tank was supposed to hold 18 gallons. One day the fuel computer showed the range as 15 miles and the gas tank still took only 15 gallons from the pump even when the car gets a mileage of more than 30 mpg. Also, the pump abruptly stops in between and I have to restart pumping the fuel. This is either a fuel guage problem showing the gas tank is nearly empty when its really not or a gas tank problem. Online research indicates that multiple people have this problem. 2) the adaptive cruise control is really jerky and slams the breaks suddenly and accelerates abruptly resulting in a very jerky ride.

Sonata comes with a 18. 5 gal gas tank. Upon fill up car will only take a maximum of 12 gallons. The supposed "range" of the cars computer show maybe 50 miles when registering near empty. Even so, only 12 gallons can be put into tank. With approximately 6 gallons that have to be still in tank, I should have a range of 180 miles at 30 miles per gallon. Gauge is in need of calibration apparently. Dealer claims to have never heard of this issue even though it happens upon every fill up.

Brand new car purchased and few issues. 1. Gas gauge only goes up to 7/8 even with full tank fill up. 2. Gas mileage does not seem to indicate correct mileage. With full tank gas, the indicator shows 450+ miles, but actual mileage is 300~350 miles. 3. Error occurs when playing songs from iphone 6 using usb cable.
