When filling up the gas tank on 3 separate occasions the station pump failed to cut off causing fuel to leak unto the surrounding surface. The Kia K 5 is leased vehicle that I entered into contract in July 2021. The car was used as a demo and I find it suspicious that the dealership wasn’t aware of the issue. The dealership is replacing the gas tank at no cost to me.

Purchased new Kia K5 LXS few months ago. Originally warning lights appeared on dashboard. At first windows would come down intermittently. Now my windows won't come down at all. My headlights flicker and turn off at night. Car sounds like it's powering down at times. Contacted dealership a number of times. Alerted dealership of problems and concerns via phone and during service. Met with indifference and treated like they hadn't talked to me regarding latest concerns. This shouldn't happen to any vehicle especially when purchased brand new.

I WAS TRAVELING 45 MPH IN MY 2021 K5 GT LINE WHEN AN OLDER TOYOTA CAMRY CROSSED MY PATH. I APPLIED BRAKES BUT THERE WAS NO AVOIDING THE COLLISION. I BROADSIDED THE CAMRY AT SOMEWHERE BETWEEN 30 AND 35 MPH. I SUSTAINED INJURIES TO BOTH KNEES, NECK AND BACK. AIR BAGS DID NOT DEPLOY. POLICE, WRECKER DRIVER AND BODY SHOP (IN THIER PREVIOUS EXPERIENCES) ALL SAY THEY ARE SURPRISED THE AIR BAGS WERE NOT TRIGGERED BEING THE FACT IT WAS A FRONTAL COLLISION. ANOTHER CONCERN IS THE FOLDING SEAT BEHIND THE DRIVER'S SIDE BROKE FREE OF THE LATCH AND FOLDED ITSELF DOWN. THAT SEAT HAS NEVER BEEN FOLDED DOWN OR EVEN SAT IN FOR THAT MATTER, SO I KNOW FOR A FACT IT WAS LATCHED. SAD TO SAY MY BEAUTIFUL BRAND NEW K5 THAT I HAVE HAD FOR 2 MONTHS NOW HAS CLOSE TO $13,000 DAMAGE. MOST IMPORTANTLY, I AM NOW SCARED TO DRIVE THIS THING. WHAT IF THIS HAPPENS AGAIN?
