2018 Kia NIRO: complaints, problems and recalls

ENGINE/TRANSMISSION BECOMES VERY SLUGGISH AS TEMPERATURES DROP AND THE TRANSMISSION SEEMS TO BE "ENGINE BRAKING" THE VEHICLE, MAKING COASTING NEARLY IMPOSSIBLE. PUTTING THE VEHICLE IN NEUTRAL ALLOWED THE CAR TO NORMALLY COAST BUT ONCE BACK IN DRIVE, ACCELERATION WAS TAXING. THE VEHICLE LACKS ANY POWER AND IS RUINING THE FUEL ECONOMY TRYING TO GET THE CAR UP TO SPEED.

WIRING HARNESS CHEWED UP BY RODENTS 6 WEEKS AFTER BUYING CAR NEW. ONLY 1900 MILES ON CAR.

NO INCIDENT TO REPORT. DESIGN SAFETY ISSUE. THE DESIGN OF THE EMERGENCY LIFTGATE SAFETY RELEASE REQUIRES THE USE OF THE VEHICLE'S MECHANICAL KEY TO EXIT THE VEHICLE THROUGH THE REAR LIFTGATE IN AN EMERGENCY (SEE OWNERS MANUAL PAGE 4-26. THE NEED TO HAVE A KEY IN HAND UTTERLY DEFEATS THE INTENDED CONCEPT OF AN EMERGENCY RELEASE. THIS DESIGN WOULD BE COMPLETELY UNACCEPTABLE FOR THE TRUNK OF A SEDAN AND IT SHOULD ALSO BE UNACCEPTABLE FOR A HATCHBACK OR LIFTGATE. A RELATIVELY INEXPENSIVE FIX WOULD BE TO INSTALL A SIMPLE METAL LEVER IN THE DOOR TH…
