When driving, I would get an unusual loud alarm sound, then the car start to cut off, couldn't stop the car using the brakes, had to wait until it slows down, usually when I'm in traffic, which is dangerous. This has happened several times off/on, I would get warning saying check brake, when all this is happening, no warning before the alarm sound or when the car has cutoff. Took car to Hyundai in olive branch, ms on 04/22/2022, therefore it has not been repaired, I was not offered a loaner car, I asked for a loaner, she (lexi) quickly said "they don't offer loaner cars" so I'm having to borrow a vehicle to get to work. I've called, left messages, no one has returned my calls.

Hyundai recalled my vehicle twice for GDI ENGINE INSPECTION/REPLACEMENT (Recall 132). Subsequently, my vehicle was recalled a 3rd time for HIGH-PRESSURE FUEL PIPE INSPECTION AND REPLACEMENT (Recall 180). During this recall, the dealership inspected and DID NOT replace or repair any equipment. 4/12/2022 I smelled gasoline and took my vehicle to an Auto Shop for inspection. The technician explained that the HIGH-PRESSURE FUEL SYSTEM was leaking fuel significantly and was an extreme safety hazard. I contacted Hyundai Manufacturer right away due to my knowledge of Recall 180. Hyundai set me up with a Dealership Service appointment and I had the vehicle towed to the dealership for safety. The Dealership refuses to honor the recall (Recall 180) and after several phone calls, emails, and tweets; I am still unable to get reconciliation from Hyundai Consumer Affairs. For context, please understand that this Dealership is the same Dealership that FAILED to repair or replace anything when I took my vehicle in for recall (Recall 180). Please help!

Driving down the road my car just shut down and wouldn't start it happened once before but I was able to jump it and it worked but this time after we replace the battery and got it running there was a knocking under the hood that sounds like a rod going out or the engine is toast. There's no knocking before the engine totally just shut down it was running perfectly fine and because it started and ran fine the last time the car just died when I was driving I thought it was the battery and low and behold I replaced the battery and it turns on perfectly fine but now the knocking in the engine. It also will not drive over so many miles per hour cuz if it goes up to those miles per hour then it shuts down or the knocking gets louder and it starts to die. Again no warning about this which is why I replace the battery cuz that's what happened last time and when it came back on this time after getting the battery replaced and put in lonely hold there's knocking in the engine and it won't drive. I've seen on YouTube a guy with the same problem find out there is something recalled on the engines for the 2011 Hyundai sonata. The manufacturer replaced his engine for the same exact thing my car is doing. I just inherited this vehicle from my dad who passed away but he had just put it in his name from my brothers who passed away from COVID so I have not had this car long at all. Literally just received title in the mail. This is my only vehicle and my husband is blind and we have two kids that we have to get to and from school and very limited income right now and this problem needs to be fixed by the manufacturer because I did nothing wrong

After waiting a year later asked again and said warranty was covered due to the recall but when I took ot they denied my engine replaced saying I caused the head gasket to be replaced. Explaining the car showed no signs of over heating and just shut off once I got off the exit.

This vehicle's engine made a rattling noise and then suddenly stalled while I was driving it. I had it towed to the closest manufacturer dealership and the mechanic submitted a claim on my behalf to the manufacturer. It denied because the car has a salvage title. After reviewing your website it looks like the manufacturer can not solely deny a recall claim based on salvage title. This vehicle's engine has acted just like all the other recall's on this manufacturer, make & model.

My engine has failed due to a well known manufacturing defect. I never received the recall notice Service Campaign 953, as I am not the original owner.

My engine seized-up at approximately 125,000 miles. We were on the highway traveling about 75mph and heard an unusual sound from the engine compartment. We exited the highway on an exit ramp and at the stop, I hit the gas and lost most power - could only go about 15mph tops. Had to have it towed to my local Hyundai dealership and they determined that the engine was seized. My check engine light and low oil light were on when the problem presented. This was on 03/12/22. Thankfully this occurred when I and a buddy were traveling home from a basketball game, however, the primary driver of this car has been my 18 yo daughter - I'm SUPER glad it happened on my drive and not on hers.

As I was driving to work Saturday 3/12/22, four blocks from my home my Sonata with 064,000 miles stalled. I was able to restart the engine twice after which it made a lot of noise and, according to my mechanic, locked up. The mechanic tried to rotate the motor from the crankshaft pulley bolt and no movement, locked up. We suspect the failure may be connecting rod bearings premature wear, as has caused engine damage in the Sonata Hybrid currently on Recall. How can we determine the cause of this failure, and request satisfaction from Hyundai?

While driving, the engine in my 2011 Hyundai Sonata hybrid with the 2.4 liter engine shut off without notice (depressing the gas pedal and zero power)! I found myself and family in a difficult and potentially deadly situation as the speed limit on this road was 55mph, a large heavy duty tri axle dump truck was bearing down on my coasting car and family. I had few options from a safety stand point and had to make a snap decision. There was not a berm to pull off the road to the right side without trying to make a crash stop into the wilderness, or try to coast to the next available side street to get off the main road. As the vehicles coasting speed decreased I was very lucky that the oncoming traffic had a small gap between a another truck and a car. With few options I had to to make a decision and decided to try and make it to the side street almost causing a potential head on accident with that traffic. We were very fortunate to make it off the main road to the side street where we were now stranded. As one would realize we were very shook up emotionally do to this flaw in this vehicle. After many hours of research I see that a class action law suit was settled in 2021 for this exact engine bearing failure which seizes the engine and is now closed. From a safety stand point, reliability stand point and documented stand point a safety recall should be implemented to hold Hyundai Motor Cars responsible for all repairs to correct this safety issue. Additionally the obvious potential for the crashes and death become very apparent unless corrective action is not taken.

Out of the blue, in the middle of driving, this car stopped working. This could have been a very dangerous situation. There was absolutely no warning. Apparently, there is a recall, but it has not been publicized by Hyundai. Why was the recall not registered with the NHTSA" What efforts have been made, IN EARNEST, by Hyundai to reach owners? What advertisements, social media posts, outreach by dealers have been made? How many letters has each owner been sent, and how clear and serious was the wording on these letters" We had no idea there may be an issue with the engine, as we never received a notification from Hyundai. We never even heard of the recall until the car died in the middle of driving it. It is very dangerous that this issue exists and that no earnest effort has been made to notify the public. Not only are drivers and passengers being put in serious danger by the lack of information about this potential engine failure/potential fire, other drivers and passengers are being put at risk by having these cars out on the road. NHTSA should be advocating for the following: 1. More robust, earnest outreach on the failure issue. 2. Hyundai needs to give an accounting of how many affected vehicles have been sold in the US and how many have participated in their barely advertised recall (in order to let you know the scope of vehicles still affected.) 3. Hyundai needs to replace these engines or get these dangerous cars off the road by providing reasonable trade in value for people to stop using these cars. 4. This recall must be registered with the NHTSA and owners need to be alerted.
