Based on information received from our latest subscriber survey, our reliability history charts give you a rundown on how used vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system.

"The check engine light keeps coming on. The oxygen sensor had to be replaced, but we were warned that because of this and the length of time it took to even get the appointment, we might have to replace the catalytic converter as well. $700 later we replaced the sensor and several months later the check engine light came on again. You can't get an appointment at a Hyundai dealer for months in the Sacramento region, but we got lucky and an appointment appeared after constantly checking for weeks. This time it was determined to be the sensor again and that a software update was needed. There was no charge since it was within warranty, but several months later and the check engine light comes on intermittently. You can't get into any dialogue with Hyundai. They are overwhelmed with all sorts of issues."
