2020 Kia Stinger Problems and Top Complaints – Is Your Car A Lemon?

Fuel system and structure issues among the top complaints received by the NHTSA from vehicle owners

Updated on Author: Brian Jones

The 2020 Kia Stinger is a sports sedan that supposedly combines power and spaciousness. The automaker claims it is “built to thrill,” but many customers aren’t excited about the adventures it provides. From the defective fuel system to the shoddy structure, there’s a lot going wrong with this Kia car.

Problems with the Fuel System

As a performance-minded vehicle, the Stinger needs to include a reliable fuel system, but that doesn’t seem to be the case.

Here is one NHTSA complaint. “Fuel line connection within the engine compartment had a lock/cover that was not seated/attached. Issue was discovered after doing a thorough look over of a newly purchased vehicle in which a loose nut was found in the trunk. Upon removal of the plastic engine cover next to the non-locked fuel line, two missing bolts were found for a wire harness on top of the engine. Owner connected fuel line lock, dealer installed two bolts to the wire harness. No receipt was given since nothing was billed.”

There is, in fact, a fuel-related recall worth addressing. NHTSA Campaign Number 20V560000 talks about how the fuel pump jet nozzle might still have a plastic burr on it from the manufacturing process. This can lead to a blocked nozzle, causing an insufficient fuel supply, which reduces drive power and increases the chance of an accident. There’s not much thrill in losing engine power or stalling in the middle of the road. Unless, of course, the owner enjoys waiting hours for a tow truck.

Structural Problems

Next, by looking at the structure of the Stinger, it’s clear that there were further manufacturing issues.

Read this Edmunds review. “Rear hatch rattles. Sunroof rattles. There was a loose bolt found in the passenger side rear door as there was a nasty rattle coming from the panel. There is a ‘chirping’ sound every time I turn off the vehicle. Kia engineers state this is normal. It is the throttle body scraping the intake as it turns off.”

Again, there is another recall that shows more manufacturing issues. NHTSA Campaign Number 20V422000 states that the Rack Mounted Motor Driven Power Steering (MDPS) Assembly might not have been made correctly. Ultimately, this error can cause the steering to lock up or cause trouble during driving. Again, the only “thrill” this car is providing is the chance to learn evasive driving skills and avoid an accident.
