I've never had worse service in my life. In fact, this is the first review I've ever written about anything as I usually can't be bothered to take the time and energy.
The gist of it: Hyundai made me a new key, but in doing so they screwed up my entire electrical and my car will no longer start half of the time. I've taken my vehicle back 3 times since, and they admit it's an electrical problem from reprogramming the key, but do not know how to fix it, nor have they ever offered to reimburse or compensate me for the major problem they initiated.
More recently, I had a "peace of mind inspection" to ensure my car was safe. They reported that my flex pipe was broken but everything was fine. After going to two other mechanics, it was confirmed my flex pipe was fine and my ball joint was very loose, putting myself and anyone else in my car in great danger.
This is only surface stuff; there were many more issues that I don't want to bore you with. After e-mailing about my disappointment and wasting my time and money there repeatedly, I was reimbursed for half of their services, with no apology given.
They must be used to getting such e-mails....I'm honestly disgusted by their service managers and their whole service department's lack of integrity.
