Approximately one month ago I had a high pressure fuel pump installed in my 2018 Hyundai Tucson. While driving on the highway, about ten minutes from home, my car suddenly burst into flames. There were no warning lights in the cockpit. There was no smoke in the cabin. Another motorist flagged me down. I got out of the vehicle just in time for it to become fully engulfed in flame. It burned down on the highway. Police and fire responded. Insurance is investigating. If I was inside the vehicle, I would have certainly died.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Hyundai Tucson Fuel Cell verdict →
