What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2024 Genesis G90, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
I own a 2024 Genesis G90 with two active NHTSA recalls: 25V474 and 25V833. On April 19, 2026, the vehicle suffered a total electrical failure: “Check brake system” warning Engine would not start Electronic door handles failed; occupants trapped inside for over 20 minutes Turn signals operate abnormally The dealer previously repaired only by reset (no recall fix). This is a life-threatening safety defect affecting brakes, electrical system, and egress. Please open an investigation and enforce recall repairs. I am pursuing Lemon Law relief.

I purchased a new 2024 Genesis g90 vehicle from Key Genesis in Jacksonville Florida. I live in Navarre Florida near Pensacola so I took the vehicle into the Pensacola dealership for service. For almost a years time I have been notifying the dealership of a serious safety issue wirh the vehicle. There is a condition where the vehicle slams on the brakes on the highway for no apparent reason. The vehicle slams on the brakes at highway speeds while straddling two lanes. A vehicle in either lane being me could easily crash into the rear of my car when it does this. It took the dealership and Genesis corporate almost 8 months to confirm the problem, even though I had videos of the event happening. They wouldn't accept my video evidence. Consequently, they finally verified the problem and have been trying to fix it for months. They have no idea why it is doing this or how to fix it. But they have deemed the vehicle to be unsafe to drive and will not give it back to me. I have asked them to replace it with a new vehicle but they have refused. I went through the Lemon Law option and all they would offer me was to repurchase it for $23,000 less than what I have into it. They offered to pay me $9,000 and to keep the car but they have no idea what's wrong or how long it will take to fix it. So that offer is meaningless. I would like some help to try to get them to replace it with a new vehicle.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
