We have a 2016 Equus 45K miles. A few weeks ago the front air suspension failed. We took to a reputable independent mechanic who has been unable to resolve the issue. They installed a new compressor. The suspension works but then eventually loses air, cause unknown. No leak evident after smoke tests. The mechanic consulted a master Hyundai technician who advised resetting the electronic system. That was done but hasn't fixed issue. We towed it to a dealership. They have said replacing struts will fix issue for $5,500. We would pay that if we knew that would fix the issue, but have low confidence that will fix the problem. The dealership will pay us 10k for the vehicle as-is, and the rep actually suggested that towing to carmax would likely yield a better offer. Hyundai customer service has no suggestions and was pretty disappointing. This is our second new Hyundai and we are feeling stuck and frustrated. Any advice appreciated. Thanks!
