While accelerating the engine started to make noise. The noise almost sounded like metal stuck spinning around in a metal fan. It stopped when I let off the gas and was fine for another mile. It then started sounding again but did not stop when I let off the gas. I barely made it into a parking lot then had to call to have it towed. You can hear the noise when the car is turned on and especially when it is accelerating. The vehicle moves very slowly and the noise becomes very loud when accelerating. I have a video of the sound but cannot attach to this. It kind of sounds like the marble in a spray paint can when shaking it. I was driving up a hill on a rural 1 lane hyway.

- Henderson, NV, USA

On Tuesday April 9, 2019 my wife called me during her drive to work and told me her car was running very rough while traveling to work on a local NY parkway. She said the check engine light also came on. When she came home I tested the obd and saw that the reader said the code was P0302 which signifies a #2 cylinder failure. I was able to bring the car to a repair shop yesterday. The repair shop just called and said the #2 cylinder has no compression. After reading numerous complaints filed here and on other forums, I believe my car has experienced the type of engine failure occurring at an alarming level.

We were on a trip from Nebraska to Michigan and return. When traveling along the toll road express South of Chicago at about 65mph 02/1we both smelled "something burning". determining that it was not anything on the interior, we closed the outside air vent control and felt that it was kind of a hot electrical wire burning smell coming from the engine compartment. When we could finally exit the expressway we tried to smell around the front wheel wells and the odor seemed to have gone away. We ate lunch, let the car sit for 45 minutes and drove on, not smelling that again. The "burning odor" was present for 5-8 minutes.

Dear National Highway Traffic Safety Administration personnel, I received the attached 'product improvement campaign' notice from Hyundai for my 2015 Santa Fe sport vehicle. If you read the campaign, I think, it reads like it should be a safety recall. They state the engine can have excessive connecting rod bearing wear. How can you believe them that the engine will not happen quickly and cause an accident. I think, as usual, they are looking more at the dollars than possible loss of life. The National Highway Traffic Safety Administration should be protecting the driver, not the manufacturer. Hyundai is placing the burden of their mistake on the customer. I had the software update done, but that does not solve the safety problem. This condition limits where you can drive this vehicle. The customer cannot be too far from a dealer. They do not state how far you can drive the car once the engine light blinks on! however they do threaten you, if you drive too far, you may void the warranty. Then they ask you to accept their apologies. They do not state if they will pay to toe the vehicle to the dealer. [xxx] I could not figure out how to attach the copy of the campaign. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Hyundai Santa Fe sport 2.0 engine 2015 as I was driving down the highway going about 75-80mph I started to hear a weird noise. When I decreased my speed the noise disappeared as I began to increase my speed the noise started again. It sounded like ticking/rattling noise. There was no indication lights that something was wrong. Nothing! I had to spend money to have the SUV towed to the dealership and for the dealership to tell me that the motor is gone and that it will cost me $5,500 to have it fixed. I am not a happy camper.

My vehicle has the 2.0 turbo engine, purchased new, and since about 10,000 miles the engine/transmission has been sluggish in accelerating smoothly. Sometimes there seems to be a delay in accelerating even after the gas pedal is depressed, and then the acceleration is not smooth. It is most noticeable when needing to accelerate on an on ramp to highway or stop light and up to the 55 mph speed limit.
