 For the 1st 7 months, this car was great. I bought it brand new. Super great mileage. It is my wife's commuter car, and for about a year, she drove less than 27 miles a day, on average, thus saving a ton on gas. About twice a month, it simply did not charge overnight--frustrating. But, it stopped charging entirely, and spent 9 days in the shop at 7 months. Then, it went another 7 months of sporadic not charging, until it stopped charging entirely again. It spent 41 days in service. Since then, it has given us Hybrid System warnings requiring trips to the dealer, along with that sporadic not charging. I am taking it in for service in 2 days for it's 3rd warning since it came out about 4 months ago. Hyundai has agreed to buy it back, basically following the lemon laws of CA (I have signed an agreement forbidding me to give details). My wife and I loved the car until it stopped working. And, worse, these two long stays in service would have cost me almost $7,000, had it not been under warranty. Remember, the battery is guaranteed forever to the original owner. But, the starter system is not. I believe the same starter parts are used in the 2017 Sonata PHEV and Kia Optima PHEV too. Sad. As of January 2018, we no longer own the lemon. We now own a 2018 Accord 1.5t Touring.
