Business ProfileforFreehold Hyundai

I own a 2013 Hyundai Elantra. On march 25, 2024 i brought my car in to be evaluated for a new engine, no lights were lit up on the dashboard. After a few days it was determined I would be eligible for the engine replacement. Per dealership staff I would be responsible for aprox $718 and Hyundai would be covering the remaining- approximately $4,000. I agreed to this work and then on 4/18/24 I was made aware of a list of recommended repairs totaling aprox $2000. I declined the $2000 of recommended work. In addition to the recommended repairs I was told my "air bag light" was on. They would do a free diagnosis and get back to me. On 4/19/24 I spoke with service manager **** who made me aware that the cost of fixing the issue with the airbag (and passenger seat) would be an additional $2000. It seemed clear to me that if the light went on after having an engine removed and a new one installed it was linked and should be the dealers responsibility to resolve . **** said it was not the dealerships fault, that the passenger side air bag may or may not work and that I would be responsible for the cost. I refused to pay for the work as this happened "under their watch." Before picking up my car I reached out to sales at freehold Hyundai and asked to leave a message for ***************** Executive manager (I was told he does not have a voicemail and was off today). In addition to this I have filed a complaint with hyundai in general. Upon picking up my car and paying the $750 (tax included) for my part of the new engine I made the service associate ******** aware of my complaint with Hyundai as well as plan to report to consumer affairs and better business bureau. While I am aware that dealerships often inflate car repair prices it seems odd to me both the $4000 total bill and the fact that this dealership was going to charge me $2000 to either fix something that wasn't broken or for something that was broken by their repair people.
