Anonymous A., CO (2023 Hyundai Sonata SE 1.6-L 4 Cyl turbo)"One time, after sitting in my garage for 1 1/2 weeks car was dead. Had to be towed to dealer. Told that the computers can drain the battery. News to me. Replaced battery. Another time. car was running wildly with tach all over the place. car towed into dealer again. Replaced all fuel injectors, at 20,500 miles. Strange to me. Again, had engine malfunction light come on. Was able to drive to dealer. Told that the engine was misfiring but they did nothing. Light went out and car still runs roughly at low speed. Happy that I will be turning it in soon."

""I have now replaced 2 of the low profile tires. The tires are particularly expensive. According to the tire shop where I replaced the second one, low profile tires and our rough roads dont play well together. They said the low profile is particularly susceptible to damage when hitting pit holes, etc. And the ride rougher than a higher profile tire. So while I like the looks and handling, I will be replacing both the rims and tires as soon as I put a bit more mileage on the two newer tires.""

When we called Beaverton Hyundai we were told that since we do no drive the car on long trips or often they recommended purchasing a trickle charger [which we did] and to use it any time we don't drive the vehicle for three days or more.
