Warning... Long post.. I purchased my 2015 genesis sedan 3.8 with 54k miles on it. I noticed a slight whine at 55 which would increase under acceleration to 65 then go away. I brought it to the dealership, explained what was happening and left it with them for 3 days. The service department called me and said that they hear the noise but cannot identify where it's coming from. I told the service advisor that you didn't have to be a certified technician to know it was coming from the rear differential. His response was 'We had a Hyundai regional service rep who also rode in the car but he didn't know what it was either'. My frustration was building since it sounded like they just didn't want to fool with it. I escalated it to the Hyundai help line. Spoke to a very nice woman on the phone who was helpful. She arranged for me to bring the car back to the dealership so they could drive my car again, then drive a G80 to compare the noises at the same speeds. In short, they never did the comparison. I ended up bringing it to another dealership who tried to do a rear differential service to see if that would fix the problem. When they drained the fluid, they found metal shavings. Hyundai approved a new rear differential and a week later I got my car back with no more noise. Great, right? Not so fast...
A few days ago I started noticing a creaking noise coming from the rear. It was minimal and didn't think too much of it at first. The next day the creaking was more frequent and started getting louder. I got underneath it trying to find something but honestly had no idea what I was looking for. I popped the trunk and shook the car from side to side and finally pinpointed the noise from the passenger side rear. Got underneath it again and shook the exhaust but no noise. Brought it back to the dealership that originally told me they couldn't find the whine from the rear end. I duplicated the noise for the shop foreman and he told me it was probably just a bushing going bad and there was really nothing they could do about it. Pretty much the same lazy response I got from that service department before. I ended up making another appointment with the dealership that changed the rear diff. but they couldn't get me in for another few days. I drive for Uber and Lyft when I'm not offshore so I put alot of miles on the car and didn't want to wait. I went to the NTB I use for road force balancing and they immediately put it up on the rack. One guy got underneath with a flashlight for a couple of minutes but didn't see anything out of the ordinary. He asked another technician to put a second pair of eyes on it and... well... the rear camber bolt that holds the camber arm was almost completely backed out. No nut and no thread sticking through the other side. You bring your car in for service and trust that they'll torque things down to spec before returning it to you. We also found the leveling sensor just hanging. Maybe someone was in a rush to finish the job. Im glad it's fixed but I don't even want to think about what would've happened if that bolt would've came completely out while driving on the interstate at 75. Ive lost all faith in Hyandai service... i hear it's the only downfall of the brand. Sorry for the long post. Just wanted to share my experiences so far.
