- Components: ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE
- Summary: 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.

What a lovely ride! It feels as comfortable as sitting in your favorite chair while cruising down the road :-)

This car rides and drives better than any car I've owned. My last three cars were BMW740L, jaguar XSJ8L, Mercedes S550 and the Genesis G90 trumps them all!!
-
This is my third Equess. It holds up great. Soon, more people will realize what a great car this is.

Dollar for dollar, this car exceeded my expectations. I truly believe that when Genesis designed the G90, they had the comfort of all passengers in mind. My wife and I loved this car and were hesitant to sell it. It's a great choice, so don't hesitate to buy now!

This is my 2nd Genesis. Mechanically, they are great and a pleasure to drive. I recently put on my 3rd set of tires with about 46k on the car. This time, I went with Michelins at about $1,700 per set. I found that Michelins ride better than Continentals, which were staunchly recommended by the dealer. The front tires are a different size from the rear, so normal rotation is out of the question. Subsequently, the dealer derated the tire warranty by 50% and told me not to expect much more than 20k miles out of the tires on this vehicle. I didn't know that they were low profile tires when I bought the car (note to self - research better next time;). I had a

This car has room for improvement in areas such as radio operation and presets. Additionally, the engine performance did not meet my expectations. However, it is still a good car overall.
Josue Strosin 2024-03-09
I appreciate your interest in the car, but I must say that I was not impressed with it given the high price. While Genesis is trying to establish itself as a separate brand from Hyundai, it may take some time for it to gain recognition in the luxury market. In my opinion, this may lead to significant depreciation in the car's value. Additionally, the front end design may not appeal to everyone. I understand that you currently own an Acura RL 2000 and are satisfied with its Bose audio system. However, I believe that the Genesis G-90 has some great new features that may interest you. Thank you for sharing your thoughts on this matter.
