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 federal safety agency 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 $5,500.00 to have it fixed. I am not a happy camper.

2015 hyundai santa fe sport 2.0t 4cyl wjth the previously recalled (2011-2014) engine. Theta || gdi 2.0 was running perfectly normal one day no warning lights or messages were displayed besides my tire pressure light . I was driving about 30 miles an hour on flat paved road when the engine started making a knocking/ ticking noise very loudly , the check engine light then came on , I turned the car around to head back home which I was only 4 miles away , the car was losing power to the engine as I kept driving to make it home , I made it to the hill I live on which is steep and tried to go a little faster but the car wouldn't go over 20 MPH at this point and the noise is becoming louder and louder . I made it to my drive when the engine shut down . I turned the key off for about a minute and then tried starting it up again , it wouldn't. Turn over and made a loud clunk . I did try having the vehicle repaired as I was told the trouble code it was displaying were p0014 and p0024 , my mechanic diagnosed this as the engine timing solenoids needing to be replaced and the camshaft timing being advanced , I went ahead with the new solenoids and a complete oil change due to there being metal shavings in the oil and on the solenoids . After the repairs were complete it was test driven by the mechanic and the engine shut down once again, the brand new solenoids and oil all had been contaminated with metal shavings . I was then advised that the engine needs to be replaced at my expense as it is out of warranty. I now have a car with an outstanding balance that doesn't run and a very high mechanic bill and nothing to show for it. I will not be purchasing a replacement engine out of pocket as this is a faulty engine
