While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again. Here we are in 2022 and it stalled again. Why can't they just replace the engine? This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.

While driving on 395 in heavy traffic headed home I hit the accelerator and the car slowed down. The cars behind me almost hit me and swerved to prevent a accident pile up. I was horrified, shaking and crying because I knew I was about to be slammed from the rear. I hit the gas again and I heard a clinking noise. I knew I would not make it home. All of the lights in the dash came on. I pulled to a safe place (downtown near the Capital) and had it towed to the dealer. It was the first exit I could take. 3 weeks later, the dealer is saying it was an engine issue. My car is still covered under warranty but it appears as if they are trying to avoid replacing it. A rep called from the dealership asking about oil and I told him there was no warning lights that ever came on the dash to indicate anything was wrong; everything happened at once.

This 2015 Hyundai Sonata LTD ([XXX]) falsely indicates CEL/emissions light. When the vehicle is started and the temperature is appx. 20 or lower, the indicator immediately displays. It is solid and does not blink. This happened on -3- days this week, over approximately 7 of -9- total ignitions in that time. Various forums show the same issue. Hyundai must recall this because it is either a false warning or else is a component within their control with which they failed to manufacture safely (thus contributing to the problem(s) and CEL).

Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.

It is also known that the 2016 has the same issue. Hyundai refuses to replace the motor or cover any cost. They are saying that the car is out of warranty when it has been in the shop for oil consumption pre-mileage but they said it was normal to be a quart or 2 low.

In addition it has been proven that these quick fixes are catastrophic and will cost more than an engine maybe a life in traffic.

- Missouri City, TX, USA

During weekend road trip, on the way back, engine has developed knocking noise, unusual vibrations, and loss of power. Car was able to make it home at low speeds with minimal acceleration. Oil check revealed that all of oil was burned up over a few days, as the oil check before the weekend trip showed full levels. Dealer would not even accept looking at the car for over a month, before their first available appointment. Independent mechanic confirmed engine knocking, burned up oil. They recommended engine replacement, but were not able to complete the job as the company would not make replacement parts available to them. Dealer has finally accepted car, also confirmed knocking noise and burned up oil. It would take another month for dealer to produce a repair quote -- $14,000 for engine replacement and additional 2 months of wait time for some parts to arrive -- much higher than what I understand it typically costs for a full engine replacement, but the dealer is left as the only option to charge however much they want, as independent services are blocked from acquiring needed parts. 87,000 mi in just over 6 years of use. No warning lights on the dash. No OBD status codes. All together this would add up to at least 5 months of inoperable car, and what looks to be a very inflated repair bill. Dealer is recommending a purchase of a new car from them instead.
