NHTSA complaint #11666402

Owner complaint summary

June 2020 I purchased the car brand new 2020 Hyundai Santa Fe SE 2.5L from dealership, after the first year I started having issues with my display monitor just shutting off and my car going idle at red lights or when I’m sitting in traffic. I’ve never been in an accident and I’m not a reckless driver to my standards besides occasional potholes, the car going idle happened 3 times before I reached out to a dealership asking questions only for them to tell me, “it sounds like I’m using the start-Stop feature too much and it’s not recommended to be used often”. So I stopped using it completely. Fast forward throughout the years, it still happened about 5-10 times a year for the past few years, I’ve learned to hurry up and put it in park, give it gas, then put it in drive. Fast forward 2025, Feb I was passed due for an oil change about 300-500 miles the the oil light came on and when I check it myself the oil tank was completely empty, I assumed it was normal since I was passed due for an oil change, and a family friend told me that wasn’t normal, I follow the recommended oil change interval on my warranty paperwork 7,500 even set my car to it, after the oil change my car was fine. I took it in at 130,284 miles, fast forward June 2025, I start my car a morning for work & it’s at 135,658 miles, the oil light comes back on and I notice it’s completely empty again. 2nd time it’s happened this year, and two family friends that are licensed mechanics tell me that’s not normal especially if I’ve gotten an oil change this year & it’s seems like the engine is burning oil too quick. I took it in to get another oil change, tell them about the issue of it being empty when I’ve been this year and it doesn’t seem right, the dealership & a local quick oil change place tells me it’s due to me not bringing it in for regular maintenance. There are no lights on on my dashboard, and when I called the dealership to ask about using the lifetime powertrain warranty I have, I have to pay.
