Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Went to the dealer to report a smell coming out of the engine as well as a squeaking noise when the accelerator is pressed either stationary or in motion. The dealer representative told me that there is a recall on the car but they don't have a remedy yet. I read about the recall. On my question 'what is going to happen if the engine catches fire?' the representative told me that they haven't seen any cars of this model to catch fire yet. I wonder what needs to happen so the manufacturer is more proactive addressing an already issued recall when a severe accident like engine fire could happen? …”

“Genesis issued the recall in mid-February and there is still not a remedy. We are supposed to park our auto outside and not in the garage. As we live in Florida and it is very hot and it is hurricane season, it is intolerably hot to park outside and, in the event of a hurricane or thunderstorm with hail, we cannot park outside without risking damage to our auto. It has been nearly five months since the recall which should be sufficient time for Genesis to have a solution to the problem. …”

“Component: Engine / Turbocharger / Oil Line / Fire Risk Vehicle Problem: For the past five months, my oil light has been coming on and off sporadically (not flickering), even though mechanics and oil shops said there was no issue. A few days ago, the car started smoking out of nowhere, though it wasn’t overheating and there were no visible signs of leakage. I took it to the shop, and they diagnosed a turbocharger oil supply pipe leak that is severe and poses a fire risk. I am in a new city with no support system and have a baby. …”

NHTSA complaint #11675780, filed 2025-07

“Recall in 2020 for a Oil Supply Pipe that is leaking and could cause a fire. It was completed in 2020. The same issue just occurred on 12/22/2023 where it stared leaking again and I took it to Genesis. They are saying I need to pay out of pocket but it is the same issue as the recall which is a fire hazard. They have had my car for 2 weeks. Opened a case with Genesis but they will not cover it. I have texts from the Gensis Mechanic saying it is the same issue. There were no warning signs except for the smoke when is was already leaking.”

NHTSA complaint #11563321, filed 2024-01

“Failing oil pressure sensor which “blinds” the driver of the engines true oil levels. It occasionally causes the car to go into “limp” mode or stall which could cause unnecessary and unreasonable traffic safety hazards. This is a well known and documented critical safety defect by Genesis as they’ve already executed a recall for the issue in their home country / market of South Korea.”
