2018 Genesis G90 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

AIR BAG WARNING LIGHT COMES ON ,EVERY TRIP WE TAKE. AFTER ABOUT 500 MILES AIR BAG LIGHT COMES ON STAYS ON FOR UP TO 1000 MILES THEN GOES OUT AGAIN. LIGHT WILL COME ON WHILE DRIVING AND THEN STAYS ON EVEN WHEN STOPPED AND PARKED OVER NIGHT WHILE BEING USED ON HIGHWAY. AIR BAG WARNING WILL TURN OFF WHEN IT FEELS LIKE IT. IT HAS BEEN WORKED ON AT LEAST 4 TIMES AND STILL CONTINUES DOING THIS. THIS COULD BE A REAL SAFETY PROBLEM IF AN ACCIDENT. GENESIS SEEMS TO BE UNABLE TO FIX. *TR CONSUMER STATED WOULD LIKE TO REPORT THAT I HAVE HAD 28 ALERTS MOST ON AIR BAG FAILURE IN 20 MONTHS. BECAUSE I LEASED THE GENESIS G90 IN ARIZONA, THERE IS NO PROTECTION UNDER LEMON LAW. REQUEST THE ADMINISTRATION LOOK INTO A LEMON LAW ON LEASED VEHICLES. I HAVE A CAR THAT EVERY TIME WE TAKE IT ON A TRIP THE AIR BAGS GO OUT. GENESIS SAYS TOO BAD WE WILL RESET LIGHT OR REPAIR EVERY TIME IT HAPPENS, AND THEY DO. HOWEVER WE RIDE ON TRIPS WITH NO AIR BAGS ON A NEW CAR. *JB

From owner reports, verbatim

On 01/16/22 at approximately 2305 hours, I was driving north on PA 743. I was traveling approximately 40 MPH in a posted 55 MPH zone due to snowy weather conditions. One adult was in the front passenger seat, 2 children were in car seats in the rear driver and passenger side. The road was level and straight. Suddenly, for no apparent reason, every warning light in the dashboard illuminated at once. The LED screen was rapidly displaying messaged such as, "blind spot monitoring system malfunction, smart BDS braking system malfunction, check smart high beam, check PSB, shifter malfunction, traction control malfunction, ESC malfunction, ABS malfunction, etc...". Immediately after traction control malfunctioned, the vehicle violently fishtailed, as if on the receiving end of a PIT maneuver, and crossed over the south bound lane. It continued off of the roadway and into a ditch, stopping several feet away from a fence. At that point, nothing was functional. Restarting the vehicle multiple times did not remedy anything. The vehicle was towed to the dealership. After approximately two months, Genesis USA advised they were unable to find any issues with the vehicle and it would soon be available to be picked up. Both the dealership and a third party(hired by Genesis) inspected the vehicle . The results of the third party inspection were unavailable.
