We took the vehicle in for the ABS recall on the 2020 Genesis G80 [XXX] The Dealer changed the Fuses and told me the fuses where changed from a 10 amp to a 20 amp fuse. This seems to be the wrong way to go for a defective ABS module. Then they told me it is ok to park the car in the garage. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

It is dead everyday and I have to jump it I noticed when I attach a power source it makes very odd noises. I feel the current recall you have on the g80 2020 may be the issue. It runs extremely hot wit no warning lights showing. I have had a lot of brake dust and the car is hot fast. Also issues with usb and when connected to phone it sound like crackling and volume sounds odd unless I unplug and replug. Replaced battery twice in a year

AC stops running during very hot days, air flow stops and heat inside the car gets dangerously high. There are multiple complaints about this in a Genesis blog, and dealers are unable to reproduce the problem to find the problem. I contacted Genesis America and they cannot do anything because service technicians are unable to diagnose the problem. Genesis MUST do something about this. I can provide snapshots of the blog with the multiple complaints. This started sometime in the 2023 summer.

AC stops working while driving on hot days, airflow stops and the situation is very dangerous. Tried to get the dealer to fix it, to no avail. I've been dealing with this dangerous (temperatures reached more than 110 F, without airflow) problem for two years. We are more than 20 owners of these luxury cars experiencing the same problem. I can provide their names and VINs upon request.

The vehicle has 11,000 miles on it. I just drove from Boston, MA to Scranton, PA on Thursday 6/24/21. There were no issues and I did not hit any pot holes. On Friday morning we started driving and 3-4 miles away going about 40 mph, we noticed a problem on the right front. I pulled over and we noticed the tire was flat. I called triple A and took the car to a tire repair shop. The sidewall was worn all around the perimeter of the tire and it had a hole in the sidewall. I also noticed a bubble on the left front tire, thus both tires were replaced. I notified Continental and opened a claim with them.
