I purchased a Certified 2015 Sonata from the Elgin Hyundai dealership 2 weeks ago. There are 2 reasons for the bad review - both pre-sale and post-sale.
I was only considering certified vehicles, not regular used. I picked the car that I liked in the "Pre-Certified" category of their website, so I went to the dealership knowing specifically what I want to see and its price. When discussing numbers with the sales person (Mitch) and the sales manager (Jim Urso), they tried to charge me almost $2000 for certification (I've seen other reviews mention this too). Again, this car was already listed online as pre-certified so any certification fees were already part of the asking price. There can't possibly be any additional certification costs added by definition - the car is already listed as pre-certified (common sense). But apparently they still try to upcharge people for that. I stood my ground and eventually they gave in and agreed that there won't be extra fees for certification.
I wasn't even planning on posting a review (although people really should be aware of this, otherwise you'll get taken advantage of), if not for the post-sale problem.
This car had numerous significant scratches, which was a big problem for me. I called before coming over and they said that they checked and the car had no damages at all (lie!) . I was considering several other Hyundai dealerships that had the exact same certified car but without scratches. I clearly expressed my concern and after walking around the car with Jim (Sales Manager) and pointing out all the scratches, he agreed to fix them. I wanted to understand clearly how much of an improvement I can expect so I asked about the method that would be used to fix the scratches. Jim explained that because they can't repaint the whole hood or the whole panel of the car that has scratches, they would have a professional painting company tape up the area around each scratch and spray paint it with matching paint. He said that upon looking closely, I would still be able to tell that a scratch was there before but it would be a significant improvement and the scratches wouldn't be very noticeable at all. I agreed to those terms and had them written into the purchase contract.
I bought the car and brought it back when they told me to (several days later) to get the scratches fixed. I left the car there. The following day they called and said that everything was done so I came back to pick up the car. The car was pulled up to the front of the building. It was evening time and that area was not well lit plus it was raining slightly. I walked around the car and it looked like the scratches were fixed, so I drove off. About 10 minutes later I pulled into the first well lit gas station to inspect the car closely and this is when I clearly saw that what they did was used a touch-up pen to fill the scratches with paint - not the painting approach that was discussed and that I agreed to! And even the touch-up job was done poorly, which left a lot of white marks along the scratch which will eventually cause the metal to rust. Overall, it looked horrible. On top of that, there were some new scratches in places where this "work" was done - on the hood and on the rear bumper. The bumper literally looked like it was swiped with something. I immediately called Jim to inform him of that. He asked to give him 20-30 minutes to look into this and call me back. He never called back that night so I left him a voicemail the next day. A whole week went by after that and he still didn't call back!
At this point I sent him a detailed e-mail which he responded to with a call very quickly. But during this call he denied that he promised to fix scratches by spray painting them, said that they did their best with the touchup and offered to redo it (that really wouldn't change anything!). I don't believe that they even had a 3rd party company perform this work due to the horrible quality, but regardless, this was not what I agreed to when I was buying the car. I would have never bought it if I knew this would be the outcome - no reason to deal with scratches when there are plenty of other options available of certified cars without any significant damage. I wasted 5 hours dropping the car off and picking it up.
The bottom line, it's obvious to me that I was lied to in order to make the sale and once that was done, they felt no need to perform the promised work. So they made a very basic attempt to cover up the scratches just so they can say that they did something.
There are a dozen other Hyundai dealerships in the Chicagoland area. If you're considering buying a car, I strongly suggest you go somewhere else!
* I would consider improving my review if they come to their senses upon seeing this (and all the other reviews that I am leaving on all the major review sites) and decide to do the right thing by honoring the promised terms... but doesn't look like they even care.
