What Problems Does the 2021 Genesis G90 Have?

The 2021 Genesis G90 generally enjoys strong reliability ratings. However, some owners have reported minor issues with the infotainment system, such as occasional glitches or slow response times. Some have also noted concerns regarding the automatic emergency braking system, with instances of false alerts. Another reported issue includes minor electrical gremlins, such as issues with sensors or lighting. It's important to check the Carfax or NHTSA website for any specific recalls affecting the 2021 model year. While long-term reliability is generally good, potential buyers should pay close attention to the electronics during a pre-purchase inspection. Earlier model years (2017-2019) had some reported issues with the air suspension, so it's important to ensure that the suspension is functioning properly, especially in higher mileage vehicles. Regular maintenance, including timely oil changes and fluid checks, is crucial for maintaining the G90's long-term reliability. Addressing any minor issues promptly can help prevent them from escalating into more significant problems down the road. Overall, the 2021 G90 is considered to be a relatively reliable vehicle, but potential buyers should be aware of these potential issues.

With proper maintenance, the 2021 Genesis G90 can easily provide 150,000 to 200,000 miles or 10-15 years of service. The key to its longevity lies in adhering to the recommended maintenance schedule, using quality parts, and addressing any minor issues promptly. Long-term durability is generally good, but potential weaknesses include the infotainment system and air suspension (if equipped). Regular fluid changes and inspections can help prevent costly repairs. The engine and transmission are generally robust, but proper cooling system maintenance is crucial to avoid overheating issues.
