Vibrating Pulse when speed hits 60

[Kevin_21]

Hey guys, I have a 2011 3.8 v6 Coupe. I noticed right away when I purchased the car, it begins to vibrate/pulse, that's especially noticeable when I reach 60 mph. I thought it was the alignment but I brought it to the dealer and they said that wasn't the problem. They said they reconnected an intake manifold pcv hose. They then told me they recommend a $159 3 parts emissions service. I said no at the time. I took the car out and it still makes a very noticeable vibration at around 60 mph. I was just wondering if you guys had any ideas of what it could be.

Thanks a lot for any help!

Visit the Genesis Coupe.com forum site. There you will find a long and lengthy thread about a driveline vibration issue...requiring many parts to replace. I hope your issue is not related to the driveline lash in the rear differential. But would be a good source of info for you and your dealer to investigate.

Best of Luck.
