The car just stopped while driving.

- Reidsville, NC, USA

As we were driving on the highway at 65 mph, the car completely cut off. Fortunately, we were able to immediately steer it off the road to avoid an accident. We had it towed and the mechanic at the auto repair shop said the engine was completely shot. He advised us to have it towed to a Hyundai dealership because he had seen this same situation with other Hyundais with limited mileage and said there may be a safety recall or a class action lawsuit. My car has 60,000 miles and is well maintained.

I was driving and when turning into a parking lot, I accelerated and the vehicle stalled. It did not go suddenly when accelerating. A couple days later, I use a code reader and have a code listed as P1326. So I take it for a diagnostic at a local shop and I am told it is the Knock Sensor Detection System (KSDS). I was advised to take it to a Hyundai dealer because often these vehicles have manufacture warranty since there-??s recalls. There have been some vehicles under this recall Hyundai put out as Service Campaign 966 or 982. They have had vehicles deal with this sensor issue before. Hence why there is a campaign issued. I review to see if there are any recalls on my vehicle and tare none but there are other models listed for this particular issue for Hyundai vehicles. My vehicle was driving fine and it-??s fairly new. Low miles then suddenly this happened without warning. I believe it is a recall issue for this model as well.

Hyundai is denying a lifetime warranty claim on my 2015 Hyundai Sonata. Recalls have been completed on my vehicle and even with knock sensor recall completed my engine light is not on and they will not grant me a new engine. If though the Hyundai Dealer agrees that the engine has the bearing issue that would grant me a new engine.

2015 Hyundai Sonata - original owners. Started burning and engine light came on at 124,000 miles. Took it to dealer to be diagnosed and have oil changed. They called said engine oil was sludged up, they would not even change the oil, and said it needed the engine replaced $9500. We contacted corporate Hyundai who said there was an extended warranty on the engine if the failure was related to connecting rod bearing wear. We were assigned a case and the rep contacted the dealer who said our vehicle didn-??t qualify. In doing research we-??ve read that this damage cannot be determined without dropping the oil pan. We questioned the rep about this and was told we didn-??t qualify because of the maintenance on the vehicle.

Hello. I'd like to report an engine oil consumption problem. I owe Hyundai sonata 2015, 9 years and 5 months. I have been having engine oil consumption problem over 2 years. It was not that serious around 2023 and 2024, also I know this car has oil consumption problem, so I checked engine oil frequently and refilled it when level went down below the "L" level. Last week, I had an engine alarm whish was powertrain system problem " P2096". So I brought my car to Jeff's garage(180milles from my home) and fixed this problem. When I checked the amount of oil before I drove, level of oil was a little above "L" level. But, when the technician checked the car, they found that engine oil left 1 quart only. (I refilled the oil 4 times already for last 4 month, I drove around 2300 miles for last 4 month) They also showed me the stick without any engine oil. They changed new oil and made sure the level on the stick was above "F" level. However, after I drove around 180 miles, I found the level was between F and L. There is no oil leaking but oil consumption is getting worse. I think some of oil consumption is normal or expected, but this is too much. Please check the safety of this engine.

In 8-2021 the original engine locked up due to a crankshaft bearing lock up. The dealer replaced the entire engine with a rebuilt. It locked up within 10 seconds after I drove from the dealer due to a massive external oil leak from the engine front area. The dealer could not determine where the leak was coming from and prepared a report to reflect this. The dealer then replaced this first replaced engine with another rebuilt engine. I drove it and within 5 minutes of driving the radiator plastic side tank exploded open and lost coolant. The engine then misfired and began to smoke out the tailpipe. and engine areas. The dealer demanded I pay $1,100 for a replacement radiator and then they would confirm that the head gasket was leaking from the combustion chamber into the cooling system that exploded the radiator side tank due to overpressurization from exhaust gas. Another dealer saw that the combustion gas had a large leak that was coming out of the broken radiator plastic side tank and advised repalcing the engine with another engine and radiator. The engine locked up while driving it as a result of overheating and/or coolant inside the cylinder that has the head gasket leak. The dealer and factory refuses to repair the engine that is still under two different kinds of warranties. The warranties expire on 10-12-2025

For about a month now the power steering was going in and out and then just the other day, the power steering went completely out, I am now having it towed to the dealership today 02/11/2025. I've also had oil consumption problems to the point where there is only 1 quart of oil left in the engine when getting the oil changed, had the combustion cleaning done and no help. Hyundai said no to a new engine, car only has 102,000 miles on it, only 10 years old and Hyundai hasn't helped a bit, said that I would have to come out of pocket but I ended up having to spend $600 on the cleaning, which is absurd.

Wednesday evening [XXX] I was driving on a rural Hwy entering onto another Hwy at a one way stop sign. This stop sign was on a blind hill with a partial obstructed view from the right and left. As I pulled out onto the road to go north onto a two lane Hwy towards my home, a truck pulling a trailer came into view from the left. To me the distance looked very close, so I accelerated to avoid a possible collision. Less than a mile down the hill my vehicle lost all forward movement. I costed to a safe stop on the side of this 2 lane Hwy. No warning lights or engine check lights were on the dash just typical signs of some sort of engine failure. The electrical system was fine. Everything else was working as it should. I had no idea I didn-??t have forward acceleration until I stepped on the gas at the bottom of the hill. I costed to a safe location on the side of the road. At this point I tried to put the engine in Park from Drive. It would not go into Park. I turned the ignition off and removed the shift release button after which moved the gears to park. I attempted to restart the engine but it would not roll over. I had it towed by AAA from that point to my Hyundai dealership in Cornelius NC. They diagnosed the problem on Tuesday afternoon. The engine had seized up. I am just now learning that this is a class action suit on this particular engine. Very grateful that I was not on Hwy 77 in the fast lane or the express lane. That could possibly have escalated the failure to a deadly failure without warning and no where to pull over at higher speeds. No one should Have to die to make corporations responsible for the safety of their customers. This is our sixth or seventh Hyundai in our family. My Sonata was well maintained. This should not have happened. Will you please look at this issue for the consumers with the same car? I am still without a car or a loaner/rental and am getting ready to go back on assignment.

Location: [XXX] Description of Incident: On a rainy morning, while driving to work, I encountered a sudden lane cut-off by a speeding truck as I exited a school zone. I applied the brakes to avoid a forward collision, but the brake system failed entirely. This resulted in the loss of vehicle traction, causing the car to spin out uncontrollably. The vehicle collided with an island, bounced into oncoming traffic, and sustained severe damage, including: -??Tires ripped off the rims -??Front axle damage Injuries: I sustained a lightly sprained neck as a result of the incident. Vehicle History: The vehicle had been in the custody of the Hyundai dealership just days prior to this incident for an engine/powertrain recall and replacement. The dealership held the car for over a week to address the issue. However, shortly after retrieving the vehicle, the brake failure occurred. Observations and Concerns: -??The brake failure occurred after recent service by the manufacturer dealership. -??Hyundai vehicles are known to have documented brake system issues, which may have contributed to this incident. -??This failure nearly resulted in a life-threatening accident. Action Requested: I am requesting an investigation into the service performed during the recall and the brake system failure. It is imperative to determine accountability and address any potential defects to prevent future occurrences. [XXX] [XXX] - Victim and incident reporter.

A rod from the engine made a hole in the engine the destroyed the engine. My wife was driving on a highway wen the failure occurred. She was lucky to be able to get off the highway and safely onto medium before car came to complete stop. The dealer confirmed a rod destroyed the engine. Hyundai asked photos of the engine and other components. No warning lights came on before the failure. The only symptom was the engine was consuming a quart of oil every 1000 miles.

This is extremely hazardous cause on highway the car can stall anytime which has happened in the past. The engine has been fixed for leaks before but still is burning oil and no mechanic will touch it saying it is a common issue of hyundai. Why is this model no part of the class action lawsuit?
