Radiator Problems of Hyundai Sonata

On March 1, 2021, I noticed an odd smell while idling in line. Turned car off until it was my turn. The smell was gone once I turned it back on, so thought it was another car and drove to work. That evening, smell started again after driving a few miles to parent's house. Parked the car at parent's and arranged to drive it to mechanic the next morning after having my father confirm there was water in the radiator and the oil wasn't too low. Engine temp gauge was normal. Check engine light was on, but had been for the length of time I had car. I had it checked several times- issue would be supposedly found, but it would always come back on. I was led to believe it was a faulty sensor issue. There was nothing obviously wrong when we looked under the hood and had no reason to think it would not be safe to drive the short distance to the mechanic. Next morning, March 2, 2021, I intended to drive the car to the shop so they could address the issue causing the smell, and father followed behind. Car seemed fine at first, but after a couple of miles driving on surface streets, the smell came back. Pulled over and turned off car, thinking that I would need to have the car towed the remainder of the way. I saw something come from under hood. My father, who had been following behind, asked me to pop the hood. As I climbed back in the car to pop the hood, I realized there was smoke inside the car. I got out, told my dad that there might be a fire as there was smoke inside the car. As we had that discussion, smoke started pouring from under the hood, and we backed away from the vehicle and called 911. Within seconds, there were visible flames and the whole front of the vehicle was engulfed in flame. Today, March 10, 2021, I was made aware that 2011 Hyundai Sonatas were included in a list of vehicles known to catch fire, so I am filing this notification.

The engine consumes extraordinary amounts of engine oil. At 72,000 miles, over 70% of engine oil is lost between an oil change range of 7500 miles. Radiator fluid levels drop as well. I believe the engine has internal problems that lead to engine oil and radiator fluid to enter the combustion chamber. This has been the case since very early days and was also reported to us by other service centers. It has gotten worse over time.

While driving out of town 2 hours away from home on major highway car suddenly stopped. Had my 3 children in the back and had to get in the middle lane and turn my hazards on and call a town truck. I had to pay 300 dollars to get the car towed home. While searching online I saw a engine recall and several other recalls for the 2013 Hyundai Sonata. I called the Hyundai recall line and they set up an appointment to have the car checked out. I called Hyundai and asked if they had any tow services that they provided, they stated that I would have to pay for tow services so I then payed 60 dollars to have the car towed to Hyundai by aaa which Hyundai advices. Hyundai called and informed me the next day that they put it on the machine and that it was the engine that failed and they would have to order an engine from Hyundai they also informed me that I would be charged 150 dollars for them to get the key fob to work to the car. After Hyundai received the new engine they called and informed me that they are unable to pull the engine in and out of the car due to from end damage which included the radiator, motor blower, and head gasket and that I would have to agree to pay 2895 dollars for them to even put the engine in the car. He asked me if the dealership I bought the car from had reported any wrecks where the front end could be damaged. I then explained to the manager of Hyundai mechanics that I have a clear blue title and in order for there to be a wreck that caused front end damage I would by law have to have a savage title. I was sold the car as is from car lot but was informed there were no accident and had been certified tested. Looking online and speaking with another mechanic I was informed that radiator motor blower and head gasket are are causes due to an car running hot from engine failure. Speaking with corporate they made false promises and then declined.

First incident involves a vehicle in motion that suddenly shut down on me and I was on the interstate I had to cruise off the exit into a parking space. Car would not start back ended up taking it to the dealership and had to replace the radiator. Few months flowing that I'm headed into work and my car start smoking out of nowhere and starts rattling I pull over to the gas station and check my fluids all are full. I get the car towed to dealership all of a sudden I need a new engine. There's been several recalls for engine failures so I would like my car to be checked as well. This is a costly repair to come out of nowhere especially when I keep up with oil changes etc.

Bought car 4/2017 5 days later engine locked 4/2017 replaced by Hyundai under warranty and received back 5/2017. Was driving started smelling antifreeze, car never showed overheat, pulled over, it blew radiator cap off, bought new cap, went back to car, added fluid and cap, drive 1/10 of a mile and car cut off and would not start back. My mechanic picked up and reports water in engine and metal in oil. Same as first engine. Hyundai claims no warranty on this new engine. This engine has metal in oil the same as their recall.

After having the engine replaced under recall campaign 132 and 162, the engine oil cooler failed allowing hot motor oil to mix with engine coolant. This in turn caused most of the rubber piping to become distended, causing them to have to be replaced. Also, the radiator system needed to be flushed more than once because of the difficulty in vacating the motor oil from the system. My vehicle's water pump needed to be changed a few months later, due to it failing. A private mechanic stated that this was more than likely due to the hot motor oil mixing in the system, causing the seals on the water pump to fail. I reported this problem to the Hyundai dealership, as well as Hyundai corporate, and they both stated that this problem was not covered under the recall campaigns. I believe that the failure of the oil cooler and water pump is directly correlated with the replacement of the engine, and my private mechanic has stated the same. My vehicle was in motion on a highway when these parts failed, and if I continued without pulling over, it is highly likely that the engine would have caught fire or seized.

The thermostat housing is plastic molded over a steel (metal) core. Where the housing is bolted to the engine over the input and output coolant orifices an internal piece of plastic flaked off the steel core behind the gasket surrounding the input orifice. At rest no coolant leaked out of the cooling system. However, at operating temperature and pressure, the coolant sprayed out of the engine in a fine mist/spray. Although there was an odor of coolant while driving, all searches around the heater core, under vehicle resulted in no evidence of coolant leak. On an extended trip at 103,000 miles enough coolant evacuated the cooling system to facilitate a blown head gasket. Yet there were no warning lights indicating overheating. The blown gasket was discovered when there was a sound of gurgling liquids originating from the coolant reservoir when we reached our destination, a thick sludge of coolant and oil permeated throughout the engine, heater core, throttle body and radiator. It was during repairs the thermostat housing was found to have the interior damage. If we had been driving 30 miles further than we did, the engine would have seized at highway speed, undoubtedly causing an accident. Thank god we stopped when we did.

2013 Hyundai Sonata. Consumer writes in regards to engine oil cooler. The consumer stated there were metal shaving found in the sum pan and oil coolant mixing in the radiator. On a seperate occasion engine oil was found in the coolant system. Another, occasion oil was again entering the coolant system and the vehicle would lose power. The radiator was cracked. The vehicle was repaired, but still experienced failures.

Takata recall. . . . . . I was driving my car and I heard a loud noise, shortly thereafter, the car dashboard said that the car was running hot and it shut down in the middle of traffic. I rolled to a stop and put the car in park. I got out the car and look under the car to see if I saw anything because of the noise, and I didn't see anything. I popped the hood and noticed that the antifreeze level was not low and that the pressure was not tight on the radiator hose. So I could not understand why the car was running hot. I closed the hood and got back into the car and started the car back up because it appeared to have cool down. I drove the car to the nearest parking lot and called a tow truck to take the car to the dealership. Once the dealership look at the car, they noticed that the pulley was not on the alternator, the serpentine belt was at the bottom of the car and that was the reason the car was running hot. They said they have never seen anything like that before. New car with only 66,000 miles on it and the pulley on the alternator is completely off while driving is not safe. In rush hour traffic in the city, is not safe for me and my kids.

I was driving down the highway, the engine started making a knocking noise. No less than 30 seconds later did the car's engine make a large bag noise and I ran over what felt like parts. I coasted a while down the road and finally pulled the car over to the side of the road. Upon opening the hood I discovered oil all over the intake and exhaust manifolds as well as the radiator. I called Hyundai roadside assistance and had the car towed to faulkner Hyundai in harrisburg PA on 1/19/14. They provided a service loaner and said they would get back to me with an update on the car. I waited until Wednesday the 21st before calling them, only to find out that the engine had seized and they had already taken pictures of the damage and sent them to the Hyundai people to seek warrantee coverage. They also asked me for maintenance records on the car. I change the oil myself and always put in full synthetic, so they had me submit receipts from the auto parts store proving I bought oil and filters or the Sonata. I am now awaiting resolution from Hyundai. Will update once I have an answer from Hyundai. This is a pretty serious safety concern, the engine let go at 60+mph without warning, when it let go it blew oil all over the engine compartment and I'm sure on the road as well. Lucky I was driving early in the morning and their was very little traffic.

This vehicle was taken to the authorized service center of Hyundai on October 29,2013 for the safety recalls received from Hyundai motor America (NHTSA campaign number 13v-354 and failure of OCS recall by NHTSA). Since the service personnel insisted to do 70,000 mile service I agreed and after 1 hour he called me and said there is a leak in the radiator hose. This car has always been serviced by authorized Hyundai service centers and always had persistent problems like oil leaks (changed gaskets (paid$400), power steering leaks (paid $300), brake rotors problems which I had to pay $1300 to replace at 30,000 miles etc etc. This car comes with 10 year/100,000 bumper to bumper warranty that is fake. I had also paid ($1200) for an extended coverage for this vehicle when I bought this brand new. But Hyundai did not honor it since it was a dealer package and that dealer no more exist. On October 29,2013 after the recall service I paid $400 since the service manager said he did all that is urgent for this car. Next day morning I found my car in a pool of multiple fluids. I decided to take it back to the Hyundai dealer, but on the way the car was engulfed in smoke. I pulled over to the gas station which had a work shop, found that no coolant in the car. They filled the coolant and put a new clamp on the hose which was loose. I made a complaint to the Hyundai motor America after 2 days. Case number is 6156086. Since then I escalated the case calling them several times, but no reasonable effort from there side to help me. On November 13, the car again burned and got engulfed in huge smoke when my wife was parking in the drive way after returning from work. (I have the video on my cell phone). Again I called Hyundai America and they told me to contact the dealer. I called the dealer (Hyundai of paramus) and they said the service manager will call back. But never did.
