general problems of the 2012 Hyundai Sonata Hybrid

While driving the car on the freeway, it will jerk forward and then shortly after lose power. The car shows the battery as being barely charged. I pull over (luckily haven't been killed yet) on the side of the freeway. Let the car sit for a few minutes, restart it and the battery is half full and the car is driveable. I've read online that this is a common issue with 2012 Hyundai Sonata Hybrids. I've taken my car to a Hyundai dealership twice, and they can't find anything wrong, diagnostics show its fine. The second time I took it in they replaced the battery located in my trunk for $485. That did nothing, as the car is still randomly shutting off, and most times in the most dangerous areas of the road. I don't think Hyundai will do anything about this until numerous people are killed. Forgot to mention that sometimes when it shuts down the check oil light comes on. I've had the oil replaced and the oil sensor, so thats not the issue.

Yesterday the car drove fine untill about an hour before I went home. Then it started with the bumping/jerking when switching from electric to gas. Worse than it has ever been. Then the revving started, more than usual, and wouldn't accelerate. Then it was like the throttle stuck. Got the revving noice, but the eco wasn't burried at red, for about 1/4 mile before I was able to pull over into a parking lot. Shut off the car. Restarted and drove 1 mile to home. Revved a few times in that period.

After I exited the freeway while traveling to my mothers on thanksgiving day I was stopped at a light to turn left onto a street and when I tried to go the car would not move I had to push the gas peddle all the way down and when it finally went it jumped/jerked really bad which almost caused me to hit the car in front of me and after that it was going really slow. 2 days prior the car was lagging while slowing down to break seemed like the system wasn't reading that I want to slow down and stop which again almost caused me to have an accident. This car is a safety hazard and I only have 61,000 miles and I only had the car for 9 months. I was told it was the transmission and the car is still in the shop trying to figure out what is wrong.

Was backing out of the driveway and the check brake warning started going off. The brake pedal went to the floor. The whole system of the car shut down. My hydraulic unit failed and they will not cover it under warranty. Thank god I wasn't driving when this happened.

First incident, Sunday, September 9, 2018. While driving, car suddenly flashed warning lights, with message pertaining to the battery. Car decelerated extremely rapidly and became harder to steer. Pulled car over out of street as it lost power. It stopped. Lights remained on. Turned car off and then turned it back on. It cranked up and could be driven as if the incident never happened. There were no warning lights or warning message when the car was restarted. Second incident, Monday, September 10, 2018. While driving the car to the dealership for diagnosis of the problem, the car suddenly lost power again, the warning lights flashed again, and again it became hard to steer. This time driver was not able to pull the car over; it stopped in the street. Driver turned the car off, then turned it back on and drove to the nearest service station. A tow truck was called and the vehicle was towed to the dealership. The dealership stated the vehicle did not register any code that they could detect. They had a technician drive it from work to home each day and the vehicle never gave any problem. They could not find any problem at all with the vehicle that required service or repair. Vehicle was picked up on Saturday, September 16, 2018. The dealership waived the diagnostic fee since they were not able to diagnosis a problem. The vehicle has been traded-in. The issue was reported to Hyundai motor corporation.

Tl the contact owns a 2012 Hyundai Sonata Hybrid. The contact stated that the vehicle made an abnormal noise while driving approximately 55 mph. In addition, the charging system warning indicator illuminated. The vehicle was towed to autonation Hyundai mall of georgia (located at 3445 buford dr, buford, GA) where it was diagnosed that the compressor failed and needed to be replaced. The manufacturer was notified of the failure. The failure mileage was 70,000.

Hybrid system warning, check charging system.

After the 6th or 7th time the car is started, there is no radio sound. I have to turn the car off then back on 5 or 6 times to get the radio to engage. This happens regularly, starting a few months after I bought the car, which was brand new.

The contact owns a 2012 Hyundai Sonata Hybrid. The contact stated that while driving at approximately 45 mph, the hybrid safety warning do not drive warning light illuminated. The vehicle was towed to the dealer, who diagnosed that the bms module needed to replaced. The vehicle was repaired but the failure recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 49,000.

This problem has been getting progressively worse during the last 6 months. While driving or stopped at a light, the vehicle has sudden unexplained acceleration. The acceleration happens with or without the foot on the gas. When in drive, the driver can remove his foot from the gas and the vehicle continues to accelerate and pick up speed. The condition is extremely hazardous and warrants further investigation.

The car was at a stop light and burst into flames, all of the sonatas have this problem, all sonatas will at the least burn up the engines, transmissions, or batteries due to this problem. Out of 35 sonatas tested 35 had this problem. Contacted Hyundai USA, Hyundai fullerton, Hyundai consumer complaint line and they refuse to do anything about it . Every sonata hybird in the world, (to the best of my knowledge) will burn up the engine, transmission, or lithium batteries (which will catch fire) between 70,000 &120,000 miles, Hyundai will not warranty the failure, this is caused by a manufacture defect. . A part in the cooling system will disintegrate and crumble apart like a wet cookie, then you will have a 3/4" hose coming off the water pump pumping all the water out of the cooling system, with less then a gallon of coolant this will take 2 seconds, everything will overheat and you can throw that car away, a new engine is $7,000. 00 a transmission, $6,000. 00 lithium batteries $10,000. 00 all prices do not include installation. .

Back up camera takes 10 to 15 seconds before coming on (average 12 seconds), audio on radio, cd player and iphone music goes out occasionally, gps has failed to operate on occasion.

Pulling into traffic the car quit, leaving me starring down the oncoming traffic. I was able to coast to the side and get it restarted. This happened twice during the same day. It will also only charge the batteries to 50%, and sometime the car won't operate on only battery power. This is a potential very serious item they need to address, or start returning money to the owners. I will not drive the car until this is fixed. It is a dangerous car, never knowing when it will quit. I have since discovered this is a common problem with the Sonata Hybrid.
