The rear suspension is the attaching point for the control arms and other rear suspension components. Road salt and water can accumulate in and around the rear crossmember causing it to rust. Excessive rust could cause one or both rear control arms to separate from the crossmember resulting in a sudden change in vehicle handling, increasing the risk of a crash. Dealers will inspect the rear crossmember and repair or replace it as necessary to correct this concern.

2011 Hyundai Azera Reviews
On September 9, 2013, I spoke with Cory (Jenkins Hyundai Service Manager), he indicated that new cars have more electronics and computers as a result this car will drain the battery if it is not started or driven more frequently than two weeks. According to him there is no abnormal drain on the cars electronic system. He recommends that I take the car out for a Sunday drive weekly, of at least 30 minutes or more. My experience with other cars (2005 Cadillac STS and 2008 Cadillac DTS), has been that I leave them at an Airport or Seaport parking for as much as a month and they have started without a problem.
We are very pleased with the car overall, but it is our second car and it often sits in the garage for a week or more. When we attempt to start it, it will not start. The dealer checked it and the battery and they claim the battery and car check out without a problem.
