The vehicle then lost motive power and stalled without warning. The vehicle was towed to the dealer where the oil was changed and the vehicle operated normally. The contact stated that the failure persisted. The vehicle was taken to the dealer where metal shavings were found in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle had experienced the failure listed in NHTSA Campaign Number: 15V568000 (Engine).

"Hybrid system warning, stop safely and do not drive" and "check brake" alarm. Car immediately went into limp mode (15mph top speed). Luckily, I was not on the highway, but on residential street. Alarm was not recoverable by restarting car. Dealer says its the hydraulic brake booster and will cost $3250 to fix. Vehicle at 80,000 miles.

The contact owns a 2012 Hyundai Sonata Hybrid. The contact stated that once car has warmed up, while driving at low speed or starting to move after a stop, she vehicle hesitated and stalled while depressing the accelerator pedal. This is a serious risk hazard as the car barely moves at intersections where it is a risk of getting hit by incoming cars. There was no warning light illuminated. The contact had taken the vehicle to multiple independent mechanics as well as hyundai dealerships who were all unable to diagnose the failure due to no warning lights illuminating on the instrument panel and no codes getting registered in the ECU. The contact then got the car evaluated by another Hyundai dealership in order to exchange it for a new vehicle and mentioned this problem. This time the dealership mechanics claimed to have seen this same problem at several occasion and that the cause was failing electric motor (when warming up) which needs to be replaced along with transmission. They also said this failure would eventually lead to the car no longer being usable at all (catastrophic failure of drivetrain) The car was no longer under warranty and total repair cost around $11 000 CAN. This far exceeded the value of the car so the car could not be repaired nor re-sold. The failure pattern started to happen when mileage was approximately 110,000 miles

I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (Pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

The Air Bag sensor light will not turn off. several months ago I had brake light sensory issues that cost me $1,500.00 and now its the Air Bag light.

I was on the highway during rush hour when the car was rattling during acceleration. I was going around 75mph. The car just died in the middle of traffic and I coasted to the berm. Once stopped, it smelled like something was burning and I had my 2 small children in the back in 5 point harnesses. They couldn't unbuckle themselves and I could not get the back door to unlock with the key fob to get into the back seat to help them. Once they were able to loosen their buckles, they had to crawl through the front seat to get out. Had the car actually caught on fire, I wouldn't have been able to get my children out in time. This was the absolute scariest ordeal I've ever been in. One shop has said the engine has seized. It's now sitting at Hyundai waiting for them to look at it. No warning lights came on until the car died.

I was making a Right turn when suddenly after making the turn my car shook and started slowing down by itself. The engine light, the oil light and the EPS and battery light all turned on. I was able to pull into a parking lot and the car just stopped. After trying to restart it, I noticed smoke under the hood. No prior warning lights came on.

When arriving at a stop and then making a turn on a street vehicle came to a halt. It would not turn on again. The vehicle was able to be pushed to the side, and started to have a knocking sound from the engine, after vehicle was started . Searching thru the internet found recall campaign 312, that has same issues I experienced. Vehicle is drivable but has loud knocking sound as the speed goes up. Also, vehicle was purchased with a rebuilt title and is road worthiness.
