1 Engine Noise problem

Failure Date: 06/15/2020

I drove my car from chicago to atlanta and had no lights on the dashboard. I took the car to get an oil change and they reported no leaks and the car was good to go. Not even 30 mins after my car oil light came on, started making noises, and started smoking. My boyfriend pulled over to look under hood and seen oil in some areas and on the ground. We got it towed to two different mechanics and back to express oil change and was told it's a hole at the bottom of my car.

2 Engine Noise problem

Failure Date: 08/27/2019

Metal in the oil and making a noise. It stalled not once but twice while driving on a highway. Had to pull over then put in park and restart. Just had oil changed and it was 1000 under needing it done again. Have no idea why metal shavings would be in the oil. Pretty sure something happened with the rods now.

4 Engine Noise problem

Failure Date: 11/24/2018

Had motor replaced from a previous recall, 4days after this fix I noticed a rough idle. Went to numerous shops incld dealership was told by dealership that recall was done and any other repairs would be out of pocket. Problem has progressed from rough idle and engine noise to poor acceleration and mistimed boosts. As in when entering highway car doesnt accelerate very fast very long delay before boost intiates. Once at desired speed when slowing down car boosts without pressure to accelertator!!! now that winter has arrived, sporadically on cold start car idles even rougher and sounds as if it with shut off. When driving in traffic car idles rough then shuts off!! no power steering! no lights ! no power! this happened whilst car is in drive and in motion! I try to avoid hwys and night time driving when I can as im scared to death of this car. I purchased it used in dec2017 11 days later intial issues began with car loosing power. Now after issue was "fixed" by replacement motor same intermediate lost of power issues again but with the added boosting issue as well now.

6 Engine Noise problem

Failure Date: 05/01/2018

I'm not sure if this is an engine problem. When I would take off in my car, I accelerate and after I started going, I could push the pedal all the way to the floor and it had no power, it would almost completely stall in the road. I let off gas and push again and it would regain power and drive. No check engine light came on, no low oil, no service lights at all. All of the gauges in the dash red great and everything was normal. I started my car one day and it started making this chirping noise, almost like a bird chirping when I accelerate, but once I got up in speed the chirping stopped. I then started my car and there was a clicking, ticking type noise that got worse after 2 days. I took the car to a shop and was told it needed a new engine. Again, all gauges are completely normal, no check engine light at all to warn me there might be a problem with my car and now it cant be driven. I purchased this vehicle new. Why doesnt the check engine light or gauges work to warn of possible issues, this has to he a defect and what is the chirping, stalling, loss of power? if my engine was going bad, why did the system fail to alert me?.

7 Engine Noise problem

Failure Date: 05/04/2017

Takata recall engine rod bearing, this car has had 7 recalls. The engine can go now. I just want to get out of the car into something where the manufacture didnot rush to put together. This is the second time I've taken the car for the engine noise and the clicking. Oil is not staying in the car. "help".

8 Engine Noise problem

Failure Date: 07/18/2016

I writing because I am having issue with my vehicle. It will not crank. The battery is not dead because the lights, radio comes on, it will not crank at all I have a push botton one. I took it for a oil change on July 15 2016 and had to pay a extra $75. 00 for air filter change. Now before I got the oil change my car was fine. So on Monday 18, 2016 leaving the restaurant my car will not start. I press the botton and nothing happen I smell and saw smoke. Left up the hood nothing out of the ordinary. I read on media network, so many people having problem with their 2012 2. 0 t Sonata Hyundai, car not starting and mines is one of them. I just got the car March of last year and now the car is acting up. I don't have $1200. 00 to pay what medlin Hyundai in rocky mount can't find. The service guy says it mybe the computer of the car, when someone tried to jump start it throught it off. But I told him that before I even got a jump start. The car made a noise and white smoke came from the hood of the car. They still blaming me but I think its their fault. The services guy said that the person that change the oil and air filter the car act like it didn't want to start. So why didn't they tell me that? I feel that they mess it up or there is a issue with all the 2012 Hyundai Sonata 2. 0 t that a recall need to be so the dealership car fix the all problems free. I need this to go to ceo of Hyundai. There is something truely wrong with 2012 Hyundai 2. 0 t Sonata. And you know the dealership service don't even know what the problem is. He said it was no fuse blown, only thing they can assume that it's the computer is dysfunctional cause of the jump. But the car was smoking and didn't start before the jump. These Sonata is killing our pockets, even the use ones too expensive. I don't gave $1,000 and $1,000 to pay out, that they don't know what problem is. Got car from gabe rowe.

9 Engine Noise problem

Failure Date: 11/03/2015

I received a notice for safety recall for my car which I just bought 3 months ago from Hyundai dealership in tampa. My car is making noise from the engine as I drive. I called today to the dealership and they stated that I would have to drop the car off. I said that's fine as long as I can get a loaner so I can drive to my work. The person (jeffery martinez) refused stating that they don't have a loaner car right now. I said you are giving me appointment for Thursday and how can you tell me that the loaner is not available for Thursday? he just kept refusing and so I asked to speak to a manager and he just tells me that the manager will call me and hangs up the phone. I called this morning and talked to a person name karen and she told me that loaner cars are only for people who pay for services and that I would have to speak to an advisor for it. That person never called me! I am not happy with the service that I received from this dealership. This is not my fault that the engine is making noise due to recall and if I have to get it fixed then I should be able to get a loaner complimentary until my car is fixed.

10 Engine Noise problem

Failure Date: 11/03/2015

Concerns recall #132 it has not been established, as far as I know, how much time may elapse between the onset of the loud pinging noise and the engine malfunctioning causing a possible crash and personal injury. In view of this the time span could be a matter of seconds, minutes, or hours---- no one seems to know. If they do it has not been revealed. Because of this there are probably many people acutely afraid to drive their vehicle, I know my son is. Additionally the pinging could happen at an odd time or day or night or at an odd location making it unrealistic or unsafe to pull off the road and stop driving the car. In view of the above, this potentially puts the passengers in great harm and exposes hyndai to potentially huge and costly legal bills. Rather than waiting until the pinging starts it would seem to me that if hundai were to pick up the cost of a car rental for the owners involved, before the pinging starts, owners could drive with peace of mind and feel safe and not have to worry about how much might time ( perhaps seconds, minutes or hours) would elapse before a break down. I am sure that providing the owner¿s a free rental until this problem is resolved would be far far, cheaper and far less time consuming !!!!! doing otherwise would also have disatrous public relations implications. All of the above would seriously affect Hyundai¿s bottom line as well!! hoping after your serious review and thoughtful consideration to your current and future customers you¿ll get back to me indicating you¿ll provide a free rental to the owner¿s involved in this recall. I would like to know where the NHTSA stands on this issue and what it is doing to get hyundia to prodvide free rentals. Awaiting your response, I remain don eck.

11 Engine Noise problem

Failure Date: 03/04/2015

We purchased this 2011 sonota used from the fox dealership in grand rapids, mi. The car started with odd engine sounds on 3/3/15 while driving city & local and then stalled out. Was able to restart & 2 days later the car stalled again. After multiple tries it did restart and we got it to a shop a few blocks away. After that it would not start. The shop said the engine was frozen. After calling fox huyndai to see if they would help us, as we just bought the car in sept 2013, they would not help and only offered $4000 to install a refab motor. The shop it was at said $4500 for a new motor and neither could guarantee that the same problem wouldn't arrise. We ended up scraping out the car after 4 days of getting quotes and trying to determine our best option. The car was sold to peddle via peddle. Com. (docs attached) peddle sent a west michigan company out to pick up the car from us on 3/9 or 3/10/15.

12 Engine Noise problem

Failure Date: 12/29/2014

Without notice/warning, engine started making a metallic knocking/flapping sound with a lot of blue smoke exhaust when rapidly accelerating. Shortly after, engine oil light flickered momentarily. From past experience, I knew to pay attention to this. By the end of the same day, I added almost 5 quarts of oil. I also brought the car to local Hyundai dealer for a late afternoon (4:30pm) appointment just before new year's eve. Service advisor mentioned that "by the time the engine oil light comes on you've got less than a quart of oil left". He suggested we bring the car back when they would have more time to work on it. I planned to have 40000-mile service and expected a somewhat expensive repair, so I needed to wait until Feb 4, when I would have funds available. I brought the car for service on 2/4, and was told later that day that the engine was damaged and needed replacement. After thorough inspection, with several photos provided to factory, Hyundai refused to replace the engine under warranty repair, citing my lack of regular service. I had the car serviced at 15000 miles at the dealership where we bought the vehicle in March, 2012, but did not have any other regular service performed. Dealer (not the purchase dealer) requested Hyundai do a "goodwill repair" that would require me to pay $1900 labor, while Hyundai would pay for the engine and all fluids (~$4800). Again, Hyundai refused. I understand my accountability for overlooking regular service, which is why I agreed to pay the $1900 labor portion of a goodwill repair. However, none of this eliminates the fact that the engine oil warning light did not even flicker until after the engine was totally damaged. By Hyundai service advisor admission, there is less than 1 quart of oil left when the warning light activates. What kind of warning indicator only activates after catastrophic damage?.
