At 37mph the transmission starts to shimmy and shudder untill you reach 40mph. Working with transmission shop to have tore down soon.

We won this santa fe on ebay, flew to chicago and drove back to virginia. We absolutely love it!! Very dependable, comfortable to ride in and very fun to drive except for the problem stated in my complaint of the shudder at 40 mph which stops around 42 mph! I would own another one of these in a heartbeat if we could afford it!
