I was driving the car and it made a noise from under the hood and shut off in traffic. I tried to restart it but it won't start the engine has completely shut down.
Internal engine noise and unusual amount of oil consumption , approximately 1 qt. Per 500 miles . Found USA today dated 09/25/2015 stating posted by the NHTSA that Hyundai announced a recall of my vehicle for this exact problem but local Hyundai dealer stated that my vehicle was not covered by this safety recall.
I no longer have fog lights that entire area has melted. My tail lights go out every two or 3 weeks and the bulbs are black. There is a burning smell coming from the vehicle only when the car is being driven or parked on. The ac line that should be cold is hot. Recently the car was leaking oil and smoking the dealership said it had to do with the engine recall. My engine seized while driving in 2016 and I had to get a engine replacement. After the engine replacement my turbo went out which only allowed the car to drive slow and the engine sounded the whole time driving. It had something to do with when they replaced the engine.
9/30/2016 - while driving home from work (20-25 miles) heard a knocking in the engine while on the road and expressway. Took my car to jiffy lube because it was time for an oil change and had them check the engine and noise. They advised that the engine is bad and will need to be repaired or replaced. The miles from my last oil change was approximately 3200 miles. Took my car two blocks down the road to midas and another mechanic confirmed the engine needs to be replaced. I have taken care of the car with regular oil changes, upkeep and car maintenance. On 1/11/2016 my 2011 Hyundai Sonata engine was taken in for the recall campaign 132 at the Hyundai repair location. In June, I took my car in for service at firestone auto care because my engine light had came on and they performed an engine analysis and found my oxygen sensor was bad on 6/04/2016 and they replaced that. I cannot drive the vehicle because the engine is on its last leg, cannot accelerate because the car is not responding as it should and I fear I am risking my life as well as others on the road. The difference between driving from 9/29 to 9/30 is night and day I do not understand how an engine gives out with no warning.
While I was driving, so the car was in motion, my speed limit was around 35 mph on a city street, the car made a noise then completely stopped without warning almost causing the vehicle behind me to crash into my rear end. I was in the middle of the road, I panicked turned the ignition off and restarted the car to attempt to pull off the road to safety. The vehicle started up and I pulled back onto the road to make a right turn towards the highway, as I was driving the vehicle stopped again without warning. The people in the car behind me got out of their vehicle to check on me. The man stated, "I can push you off the road, but there is something going on with your engine or perhaps spark plugs or wires and it's not staying connected or firing off a charge, I'm not sure. " I thanked the kind stranger and immediately called hyndai customer service. The Hyundai customer service rep informed me about the engine recall notice and contacted the towing company to locate and tow my vehicle to the nearest Hyundai dealership. However, after waiting 1 hour and a half, I called the 800 number that was given to me to reference and they did not have any information on having me towed "free of charge. " the Hyundai roadside assistance rep did not have a record that hyndai customer service placed a call to them at all and further more the Hyundai customer service center was now closed. Apparently, on Sunday they close at 3pm. My car is still sitting where it stopped because the Hyundai roadside assistance needs the "approval" and reference number to tow the car on Hyundai for free. Hyundai has basically produced a "lemon" due to the fact that this particular make and model has had "several" dangerous recalls since I purchased the vehicle in March of 2011. They should be deemed unsafe and taken off the roads completely and customers should be given their money back.
Tl-the contact owns a 2011 Hyundai Sonata. The contact stated that while driving 60 mph, he heard a loud screeching noise. The contact also stated that the noise was only heard when driving on the freeway at a high rate of speed. The vehicle was not taken to a dealer or repaired and the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was 68,000. Ed.
The engine was making a noise, we changed oil as recommended but noise was still prevalent. Car was taken in, engine failure. Engine was replaced with a rebuilt engine. The called it a remanufactured engine and they sent the head out to get assembled. According to the dealer Hyundai does not have band new engines available so they must rebuild the damaged units & send them out or the dealer is told to rebuild. We have no cause the dealer & Hyundai will not tell us the truth. So we have our car back with a remanufactured engine in it not a brand new engine as promised.
While driving on a highway in the middle of traffic my 2011 Sonata completely stopped and the engine totally seized up endangering my entire family. There was no unusual engine sound prior to it stopping and no warning whatsoever. We had to coast to the side of the road, avoiding oncoming traffic. This is totally unacceptable as it endangered 5 lives. Thank goodness we were able to get to the side of the road. We are told that the engine would need to be totally replaced at a min. Engine cost of $5800 not including labor or other parts. In estimating costs, probably $8000 or more. It looks like there is a defect in the rotating assembly that causes sudden and catastrophic engine failure. Hyundai is aware of this problem and has done nothing to prevent it. Now I have no car to drive, and must somehow come up with the above costs or rent a car. The car is out of warranty but was well maintained. This is a serious problem and needs immediate attention.
