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

“The vehicle started smoking and stalled out Aug 18,2023. The vehicle starting shaking then I parked it for about two (2) hours. When I tried to crank vehicle again it wouldn’t crank. I attempted to complete diagnostic test but the vehicle wouldn’t remain on. I contacted dealership I purchased it from. They order a tow to be brought in. The dealership repair shop for about 3 weeks didn’t know what happened. The change filters and oil change but it still was stalling.”

“My 2021 Genesis G90 has experienced repeated failures of the main infotainment / viewing display system, which has been replaced multiple times by authorized Genesis dealers. Despite these repairs, the defect continues to recur. On December 19, 2025, while the main display was nonfunctional, I was involved in a rear-end collision while proceeding from a stop at a traffic light. During this event, the vehicle did not provide any forward collision warning and did not engage autonomous emergency braking, despite the presence of a vehicle directly in front of me. …”
