We owned two 2013 Hyundai Equus. Based on usage preferences one reached mileage quicker than the other but at 42K each one suffered failure of the air bag suspension. We had to use both dealerships in Dallas for the repair as one repaired the front struts proclaimed the problem solved and when it failed to be resolved we took it to the other dealer. Clearly, the dealership mechanics didn't understand the Hyundai systems. All told, it was over $8000 for the repairs. When the second car reached the same mileage recently, the right rear air strut failed. I took it to Davis Automotive for repair and held my breath. After recalibrating the system, Davis called me with news that it would require a new rear air strut and offered me two options; 1. perform the repair with a factory part for $1500 or they would order a remanufactured part and the cost would be $500 parts and labor. I opted for the cheaper route and they repaired it without issue. The final bill was $496. We are ecstatic.
