NHTSA Complaint #11451044 — 2013 HYUNDAI SANTA FE

My wife was driving down the highway on her way home from work. It was dark and at the evening rush hour,when the highway is already dangerous to be traveling on at that time. All of the sudden while traveling in the second lane her engine lost power and dropped in speed to 20 mph from 65 mph. There were no warning lights, or prior sounds ,vibrations or other symptoms to indicate an issue. She immediately became worried about trying to get the car off the highway and to a safe place, with out causing or being involve in an accident. She called me scared and didn’t want to drive it any further. After we got the car home, I checked for fouled plugs, bad coil pack, maybe bad fuel in the tank or possibly a bad or stuck injector. None of these had any issues. Our son who works at Somersworth Hyundai here in New Hampshire,as a salesman, talked to the technician there and he told us to bring the car there and he’d take a look at it. When we heard back from him the technician said that there was no compression in cylinder number 2. My safety concern is that when this the case the injectors continue to dump fuel into the cylinder. Causing excess fuel that doesn’t get combusted in the cylinder to be dumped into the exhaust manifold and out the tail pipe as a heated vapor. The concern is the fumes, the possibility of a fire igniting in the hot exhaust manifold and causing an uncontrollable situation. The technician also said if you take a bore scope you will see that a valve in the head has broken off for cylinder 2 and has caused this issue. The car has been sitting in my garage now for 4-5 months. We still owe on this car and it can’t be safely moved anywhere with out being towed.
