The vehicle was parked. I tried to turn the car on but it didn't come on, and then I noticed it smoking under the hood. About 5 minutes later there were flames coming from under the hood and quickly spread to the rest of the car.

Stopped at a stoplight with the engine running, gear in drive and the brake depressed, but the engine started to rev and lurch forward--with my foot still on the brake. Moved forward a couple of feet with my foot still on the foot brake but finally came to a stop on its own.

The car is under recall for rod bearings but the Hyundai corporation has not authorized the fix. The paper that I received from Hyundai states what the fix is (know sensor). It is unsafe to drive to the car but no action has been taken to proceed with the known fix. The recall was announced is Dec 2020. I have had a couple of incidents where the check engine has been activated when driving. When I take to the dealer, they always find an unrelated problem which to me seems suspicious. I do not whether to sell the car or keep waiting for the already known fix. My car has been services at mission hills, Hyundai.

Went to start car on wed an was making a very loud noise. Shut it off and check fluids and everything was fine. Had car towed to dealer and the inspected it. Told me it was metal in the engine and motor was shot. Was told that it would be $14000 for a new engine out of my pocket. This is the reason for the recall and now my car is disabled. I am without a vehicle until this matter is resolved. I have video from the dealer but it wont let me send it for my report.

I have done an oil consumption test with Hyundai that proves my oil is burning extremely fast. It also stalls and the acceleration has slowed down. When costarring up the car it sounds loud. This problem has been going on since 2020. As of Feb. 2021 Hyundai stated that my problem with my engine will not be solved because of the oil consumption.

This car has had episodes of the engine dying while driving at least since 2014. My father, the primary driver and caretaker of the car has never received any mention of a Hyundai recall for this. This same event has happened several times again, and every mechanic we have taken it to for repair concludes that they can't figure out the problem, because they can't replicate it. This is also the consensus from our local Hyundai dealship mechanics.this car is dangerous to drive!!! it has been in the service shop at the Hyundai dealship for over a week now. Hyunda customer customer care has told me that they can't do anything, because their computer system is down. So, here we are, without the car, and no answers. My father died in 2019, but he kept every piece of paperwork for that car, including recalls for the air bag, seat belts, etc. He had everything fixed that needed to be fixed on that car, and there is no record of a recall sent to him regarding the recall I mentioned.

The contact owns a 2012 Hyundai Sonata. The contact stated while driving 50 mph or higher, the vehicle would shake and make loud noises while turning. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to faulkner Hyundai philadelphia (11500 roosevelt blvd, philadelphia, pa 19116) where the failure could not be diagnosed due to the diagnostic computer being inoperable. The vehicle was not repaired. The contact stated that the failure was related to NHTSA campaign number: 18V934000 (engine, fuel system, gasoline) however, the dealer declined to repair the recall because the contact did not want to pay the diagnostic fee. The manufacturer was not informed of the failure. The failure mileage was approximately 97,000.

Vehicle in motion, less than 40 mph on a city street with a slight incline, less than three miles from home. Vehicle started to operate sluggishly without warning, with lack of power when accelerating. The check engine light started flashing, acceleration severely decreased and was unable to go over 20 mph (car was placed in limp/engine protection mode). I slowly drove the car home and was able to troubleshoot the issue. Connected on obd2 scanner and immediately received a dtc P1326; indicating the knock sensor detection system placed the car in limp mode due to a detected knock/vibration in the motor. Further research proved service campaign 953 (tsb 19-01-002H-1) was already opened in late 2018 to help resolve the P1326 issue and many 2011-2018 Sonatas were recalled to get a software update for the ksds; as an early preventive measure for possible faulty bearings/rods in the motor. I had the vehicle towed to my local Hyundai dealership to get the ksds software update after receiving the P1326 dtc. The service tech said my VIN was not part of a recall or campaign and charged me $173 to update the software and clear limp mode. The Hyundai tsb clearly states this update is free to the customer and applies to all Sonatas from 2011-2018; regardless if the vehicle was not part of the original recall.

I currently have a 2012 Hyundai Sonata hybrid with an active loan. I took my car to a local dealership from carmax's repair pal certified shops because my car was shaking and producing a rattling sound. I drove my car to the car repair and was later told my car is no longer starting up and they needed me to get it towed off their lot at my expense. I towed the car to a Hyundai repair shop. I was told that my engine is dead and I need a new one. The quote was approximately $10,000 to get a new engine. The insurance company refused to pay for the engine. My car now sits in front of my home (inoperable) while I'm paying off the loan. I cannot afford a new car. I was not told about an engine recall for this model.

Sonata

  • 150,000 miles
Sometimes when I press the gas, the car will basically take an extra second to speed up, and probably 70% of the times that I press the brakes to slow down or come to a stop, itll (also) take an extra second and itll stall/jerk 1 time, then finish slowing down or stopping....its gradually been getting worse as time passes...the engine needs some work definitely! (I'll feel much more safe after this engine recall is fixed!)

I was driving on a city street when the check engine light started flashing. The car started knocking not running well. When I took it to the repair shop they stated I would have to replace the engine because it had seized. The repair shop also stated they had replaced 20 of the same model within the past 12 months. We are currently working with the extended warranty company to see if they will cover it. We have maintained the engine with regular oil changes
