NHTSA complaint #11540653

Owner complaint summary

After getting routine maintenance done on 5/29/2023 at Courtesy Hyundai in Tampa, my vehicle stalled numerous times when running the A/C. The compressor kicks on, RPM drops and the car violently jerks before shutting off. The system will only restore if I turn the A/C off. So I assumed the issue was due to the A/C putting pressure on the vehicle. I took it back to the same dealership on 6/6/2023 and they performed a fuel sample and said there was bad gas (high water content) in the tank (even though I only use 93 octane gas from a premium gas station, Shell) and stated the fix action would be to drain the fuel and clean the injectors for $850. I declined because I didn't believe that was truly the problem and wanted a second opinion from a different Genesis dealership. About three weeks later, I was merging on the interstate going 65 miles per hour and the vehicle stalled, lost power and came to an immediate stop. Absolutely nothing worked!!! I almost got hit by multiple vehicles. I waited a few minutes before restarting and the vehicle drove like nothing was wrong. However, this problem continued several times as I was trying to get home. I did notice it was having difficulty accelerating after that. I would say this vehicle randomly stalled in moving traffic more than 10 times in a two month period. I was finally able to get a service appointment with Lakeland Genesis on August 4th. After about a week, I was notified the fuel pump is indeed bad and needs to be replaced, which is what I thought initially. The vehicle has not been repaired yet because the part is on backorder with no ETA. So I'm unsure if replacing the fuel pump is the final fix. We are part of an online GV70 forum and it seems many other owners are going through this same issue. This is extremely dangerous and someone is going to be seriously injured or killed because the vehicle stalls with no warning lights, no alerts, no error codes, no nothing.
