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.

Sonata 4-cyl

  • 97,000 miles
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.

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

I had a very scary incident Friday night, 12/18/20 about 8:30pm. I was about to merge onto the 5 fwy North to go home, and as I am coming out of the turn, and accelerating to anticipate the flow of traffic, I see a big rig in my rear view mirror in the distance. Naturally, I step on the gas to punch it, to give myself and the rig plenty of distance as to not collide. My car revved up and decelerates to about 2mph. I panicked and managed to coast the car to the shoulder as far right as I could and the rig barrels down past me. I was afraid to completely stop on the shoulder of the fwy, and the car lasted long enough to coast to the next exit. I am able to continue steering my car close to the shoulder at a crawling pace, and turned on my hazard lights. I had people mad behind me, but I could not speed up. I managed to coast to the nearest exit, come down the ramp, and stop briefly with just enough momentum to steer left onto telegraph in commerce, and my car completely dies in the first lane. This is the second time my car just dies on me while I am driving! first time was three years ago in December 2017. The car had initially died while making a left turn. However, after turning the car off and waiting a few minutes, I was able to turn the car on and drive no more than 30 mph to the same downey Hyundai. The issue was under full warranty and repaired, but now a second time? worse yet, this happened while excelerating onto the freeway. I don't want to drive around in a car that has repeated recalls for various issues. I also don't want to worry of my car dying on me a third time. My Sonata is currently at downey Hyundai and they have started diagnostics and will have a better reading as to what happened. I have lost all confidence in this vehicle and worried for my safety and that of any passengers I may have with me.

My engine threw a rod at approx. 85000 miles (10/2019). Hyundai replaced the short block but since then I continue to have issues with my car. After they replaced the short block and I picked my car up, the car seemed to be running like it is not getting consistent fuel like it is supposed to. I have had it in the shop 4 times because the check engine light has come on. While I am driving, the car seems to lurch at random times and this issue has gotten so bad that this (what I call lurching) makes the cruise control shut off. One time I was using the cruise control to accelerate onto the freeway and the warning bells and whistles went off, the car stalled, then restarted itself with no check engine light on. The most recent time (10/26/20 - 11/10/20), they had my car for 6 weeks, they did not fix it. They put 337 miles on my car while they had it and I experienced the same issues I have been complaining about to them since the beginning, after I drove it 38 miles. They cannot seem to find what is wrong with my car or fix it. 10/2019 threw rod - replaced short block see attached 1/3/2020 replaced hsg belt - did not fix issue see attached date unknown - check engine light went off before they could run codes.unable to find issues - did nothing no paperwork 7/3/2020 - unable to duplicate concerns, provided software updates. 8/20/2020 I called san tan Hyundai and told them I continued to have the same issues. I told them I needed a loaner car as I have no other means of transportation. I was advised they did not have one available but would call me when they did. They never called. The check engine light came on again on 10/25 while I was out of town so I took it to them 10/26. I have paid for 2 rental cars now while trying to get this issue resolved. 10/26/20 trans reset recycle cleared codes - did not fix issue see attached

12/12/2020 at 7:00am less than a mile from home my car stalled on a country road. As I was going up the hill I heard a knocking noise. When I reached to the top of the hill the car lost power and all of the lights/symbols on the dashboard came on. The car coasted and then I applied the brakes. I tried to restart the car, tested the battery and check the oil dip stick. There was no oil on the dip stick. Soon after someone said the could see smoke and smell an acrid odor. The vehicle was towed to the authorized Hyundai dealer. This dealer does my vehicle maintenance and oil changes.they told me the vehicle needs a new engine. Nothing was mentioned about the recall or giving me a loaner/rental car. I was told it could take weeks or months for a new engine to come from pr, usa or Korea. The authorized dealer has not told me how the process works. Only that the repair will be covered at no cost to me.

I have had nothing but issues with the vehicle also the Hyundai dealership. I have taken my car in 5 or more times because of issues. The most recent because of a continuous incident of loss of power during commute. My car lost power from the turbo. Sounds like its dying out and struggles to stay on.. dealerships number one stated because of turbo failed so its not covered because it is not part of the engine. Then the second dealer told me its the waste gate so its not covered because it is not apart of the internal engine. Said that is would cost more than 2,000 to fix and my car barely 9 years old...... so I don't have the money to fix the car the dealership allowed me to drive away in a dangerous death trap and nothing fixed. Thats just one issue amongst a ton of recalls that apparently do not affect my car.

My car stalls all of the sudden out the blue during driving sometimes it kills causing me to almost get hit a couple times because it just goes out during driving. It has a misfire and a strong scent of exhaust coming from the car. I have take it to mike morgan hyuandi in Louisiana where the mechanic clearly tells me they feel the misfire and smell the exhaust but no engine lights are on so no codes can be read and they cant do anything. He even told me if I'm driving and the car stalls try to get a video of the rpms of what the car is doing and reading during that time so he can have something to go off of, boy how unsafe was that advice. I have taken this car to gateway as well as a local mechanic all who has put it on the diagnostic machine yet still noone can find the issue because again it has no check engine lights on so what do I do. I dont have money to just buy parts and hope that fixes it. The car drinks oil but there is no visible oil leaks. No droppings in my drive way. Some one told me the PCV valve may needs to be changed but again I dont have money to keep changing out parts hoping thats it. This is a known issue with these cars and I feel hyuandi needs to do something because it's nothing that all consumers are doing wrong the motors are just no good
