 I purchased my Elantra GT new, and have driven it for four years, putting about 70K miles on it. For the most part, the car has been comfortable and reliable and trouble-free. As is well known, the true MPG is nowhere near the marketing claims by Hyundai (and there is an unresolved class action lawsuit underway to address that). I also had a problem where the rear quarter-panel window trim fell off - fortunately I found a TSB published on the internet about that, so Hyundai fixed it under warranty. However, I recently had a problem where the clutch started chattering/slipping. My mechanic discovered that the transmission input shaft seal was defective/leaking. Even though this is covered by the Hyundai 10 year/100K warranty - Hyundai refused to honor the warranty and pay for the repair. So if you are considering buying a Hyundai vehicle, I would recommend purchasing instead a vehicle with higher quality/reliability and from a manufacturer who stands behind their product and their warranty commitments (think Honda, Toyota, Mazda). And definitely don't count on the Hyundai 10 year/100K warranty actually providing you any protection from product defects.UPDATE OCT 2017:Hyundai continues to disappoint me with their terrible customer service. They truly seem not to care whether or not their customers are happy with their Hyundai vehicle. At this point in time (after having been a loyal multiple-car Hyundai customer) I have zero loyalty toward them, and I will definitely not even consider ever purchasing another Hyundai product again. Honda offers much superior products and customer service! My advice to anyone considering buying a Hyundai vehicle is DON'T DO IT!!!
