Please read this review. This is an honest assessment of the lackluster service that I received from Centennial Hyundai. I brought my car in on Wednesday, 10/21/2020 for an appointment. I explained to the service writer that the car was making a noise at cold start-up and provided him a video of the noise. I further explained that I thought it was the CVVT or something oil related. Some time late Thursday I contacted the service writer to find the status of the car. The service writer explained that he had called the warranty company and they had informed him that the claim that he had put in for a timing belt tensioner was declined, since it was replaced by another Hyundai dealer earlier. I explained to him that I had no reason to believe it is the timing belt tensioner, and therefore it should be covered. He was very timid, but respectful, and said he would get in touch with the service manager to discuss this. Several days went by, the service manager was off on Saturday, the service writer was off on Monday. On Tuesday, 10/27/2020, a week later, I called the service writer and asked him if I needed to get involved with the warranty company. He very timidly explained that no, he would contact them one more time to see if he could get them to move forward on the CVVT. This is after he had already mistakenly put in a claim for the timing belt tensioner, which we had discussed was not the problem. I called him back around lunch on Tuesday and he explained that the warranty company was adamant about rejecting the claim, and that he suggested I go back to the other Hyundai dealer. I could tell by the tone in his voice that he really didn't push for this claim. I decided to call and talk to the warranty company. The warranty company explained to me that the claim was put in to fix the timing belt tensioner, and that is why the claim was denied. They further explained that if a CVVT was required, they were not rejecting the claim at all. They also suggested that I go back to the other Hyundai dealer because if it was by chance the tensioner, which I told them it wasn't, (turns out I was right) it would be covered under the parts warranty, but if not the other Hyundai dealer could put in a claim for the CVVT. My problem with the service advisor is that he never really listened to me, was completely inadequate in his timeliness or ability to get back to me, and was not very proactive in taking on this case. In fact he was extremely tentative. He was, however, always professional. On Tuesday afternoon, a week later, when I came to pick up the car, I was charged $76.43. The service writer explained to me that he was giving me a discount off the diagnostic fee. What a joke. I personally don't see this as a discount. My car was kept for a week, instead of the couple days it should have taken, the diagnosis was incorrect, and in fact, the way this was handled, actually further complicated my situation. I sent an email to the service manager and service advisor prior to leaving this negative review, but no response, imagine that. Please trust me and take your business elsewhere, you will be much better off.
