2015 Hyundai Tucson

My husband had taken my vehicle to work one day. He called me and told me that the car had shut off and wouldn’t restart. He had just turned onto a major highway and was able to pull off to the side of the road. We thought it might have been the key fob, so I brought the other fob with me. Still nothing. The brakes were stiff and the dash would light up, but the engine wouldn’t turn over. We had the car towed back to our home. We replaced the battery and starter, and after doing research, have come to the conclusion there is something in the engine that is causing the engine to not turn over. We believe we’ve narrowed it to the timing chain. Our next step is to take it to the dealership and have it evaluated, but possibly looking to upgrade.

After inspection by the mechanic it was determined that the engine seized. The vehicle is currently at the garage and is available. At the time the engine seized we were on the highway with a speed limit of 70 mph. The vehicle shut off but luckily I was able to pull over safely onto the shoulder. I had my entire family in the vehicle so I definitely feel our safety was at risk. The vehicle has only been inspected by my mechanic. The oil was changed less than two months ago and was changed at regular intervals. There was no warning lights or messages prior to the vehicle losing power. Once it lost power the oil light and engine light came on.

Our 2015 Tucson has the G4NC DOHC GDI engine, which unfortunately isn’t listed in any current engine settlement as of the writing of this complaint. Our engine started to rev at considerably high rpms while driving up hill, followed by a subsequent loss of power and speed. We managed to make it to the top of the hill and pull over, traversing over multiple lanes in front of on-coming semi trucks and other fast moving traffic with our hazards on. Upon pulling over, our engine died. There were no red or amber warning/caution lights on the dash, nor did the check engine light illuminate during the incident. After a few attempts at restarting the engine, we finally got it started and drove it home and brought it to the dealer the next day. They diagnosed it as a “clogged catalytic converter.” Although seemingly a secondary issue, and no further information as to what actually caused the clog in the vehicle inspection report, we reluctantly dished out the $3,200 for the repair of the vehicle we so desperately needed for work. They also installed a “knock-sensor” update. A couple months later… When driving the vehicle to work, the check engine light illuminates and flashes on and off continually. After pulling the vehicle over to a stop and consulting a Hyundai mechanic, I had the vehicle towed to a Hyundai dealership for diagnostics. Turns out the knock sensor update is what caused the engine light to illuminate to “prevent severe engine damage,” and I’m left with a large bill for engine repairs. Will the G4NC engine be investigated by the NHTSA? Will Hyundai honor my drive train warranty? Will Hyundai Corporate ever call me back? Tune in next week…

Oil consumption. Why is my car using so much oil? I do regular oil changes and I’m always 1 -2 quarts low when I go in for my oil changes. Last oil change. I was told to come back in 1000 miles. I’m 300 miles shy of that and I checked it and I was already a quart low. With all the complaints that I’ve just read. You’d think you a recall be done. Or taking the cars off the market. What I’m a supposed to do in the meantime about this? Help!! Emmett Idaho

Driving down the street and the vehicle suddenly shut off in the middle of the roadway. Vehicle would not restart. Engine oil leaking out of tail pipe was noticed when vehicle was being placed on tow truck. Towed to Hyundai. They say seized engine and not covered under warranty due to low oil. No lights came on dash to include low oil or check engine. Only 66,000 miles. Oil last changed less than 4,000 miles. If there was no oil then how is it possible oil leaking from tail pipe. Looked at similar complaints. Appears rods and bearings are braking in these motors. 55 mph road when car suddenly shut off. Could have seriously injured driver. Could have caused serious accident. Hyundai does not stand by their product and warranty.

My engine ceased while driving, leaving me stranded on the road. I had it towed to the nearest Hyundai dealer that was supposed to do any warranty repairs. Prior to this, I was needing to replace the oil, about 1 quart per week. I did my routine service maintenance and they tried replacing a seal or gasket but that did not stop the problem from reoccurring. When the car was brought to the dealer, the oil was low but there still was some oil in the engine. My engine light never came on to warn me about any issues. The car was sluggish and sputter which was when I would check the oil and put more oil in. I know there was a lawsuit which was settled with engine problems for the same make, year and model as mine but I have not received any recall notice for engine problems for my vehicle.

There are a lot of reports stating that Hyundai doors stop opening and a recall should be done to fix the problem. I had my rear passenger door stop opening from the inside and outside of the vehicle. It is a safety issue in case of an accident and I’m am not able to get into that door to get to my children in the back seat especially if the other door is damaged in the accident or if there is a car fire. Please check into this it is a safety issue and my vehicle only has 67000 miles on it.

On date of incident, I had accelerated to enter onto the Major Deegan Expressway in Bronx,NY and made my way into the left lane when I felt the vehicle hesitate a second and downshifted in speed with some of the dashboard lights turning on. I was able to safely get to the emergency shoulder where the vehicle stopped and would not start again thought it had power. I was towed off the highway some hours later. The vehicle was towed to Central Avenue Hyundai in Hartsdale,NY for service on September 7, 2021 under my Hyundai warranty plan. A few days later I was advised by Ryan of the service area that the engine was the problem and needed to be replaced. Currently awaiting approval from warranty for that work to take place.
