I bought this car brand new, 2 miles on odometer. Castrol Ultra Full Synthetic oil, changed at 4-5 thousand miles. And serviced by the book plus. I have been complaining to dealer for the last 3 years [ starting at 70,000 miles ] about this rattling at startup and they would say this was a new type engine and it just sounded different than what I was used to. As it got worse I had to take in at different times, to fix air conditioner, to replace headlights, replace both front axles, airbag recall, seat belt recall. It has been left at dealer on several occasions, every time I mentioned checking this problem. Usually I would be told they never heard it, which is a lie there is no way not to hear it. I am afraid to even touch the gas pedal till it warms up yet they don't hear it... Well at 99900 miles once again I left at dealer, concerned that my warranty was about to expire, I expressed my concern about this problem. Picked it up a few days later and once again I was told they did not hear any problem. So now here I am at 103,000 and find this site where it is a well known serious problem, which is what I thought. Now what. There should be something done about this, isn't this some kind of fraud or something ?

On 25/1/2011, I purchased a new 2011 Hyundai ix35 in Melbourne, Australia

Late in 2017 I noticed a pinging/rattling noise underneath the car when it started and I began driving. I reported this concern to Hyundai service centre on 2/1/2018 during a 72 month service. My car had 8586 0km. The mechanics carried out a check of this concern during a road test but couldn't reproduce my concern. Over 2018 this rattling/pinging got louder and lasted longer. I again had it serviced at Hyundai on 10/1/2019. It had done 95,282 km. The mechanics mentioned nothing about this rattling/pinging noise even though the problem was still there. I continued to drive noticing the noise was louder and more sustained throughout each journey, and decided to take it back to the same Hyundai service centre on 4/7/2019. It had approx 100,020 km. I told them about the increased loudness and pinging of the noise, how this gets louder when accelerating in the lower speeds, how car doesn't start immediately now, smell of fumes in the cabin and it drops in power when driving. At no stage in this 18-21 months of concern did any engine warning lights come on to indicate there was a problem.

On 10/7/2019 Doncaster Hyundai reported that my engine was damaged, the car was unsafe to drive & could stop at any time due to the engine problems. They noted the knocking noise was coming from the engine and noted: Metal filings (swarf) in engine & found excessive clearance in big end bearings causing the engine noise.

I rang Hyundai Customer care on 11/7/2019 about my concern and who should have to pay for a replacement engine. They just told me that as it has passed its five year warranty and there is nothing we can do. I understand that under the Australian Consumer Law, when I buy products and services they come with automatic guarantees that they will work and do what I asked for.

The cost to repair my engine was $6,500 (AUS), which I 'paid under protest' (12/8/19) due to nobody (Manufacturer; dealer, mechanics) claiming responsibility.

I expected more from Hyundai and feel their engine was not built to an acceptable quality. I have had the car serviced regularly within the manufacturers’ guidelines, at Hyundai dealers. I have also driven it carefully and within the Victorian speed limits. And for the engine to initially show problems before 85,000km (late 2017) and finally be un-drivable at 100,000km (July 2019) is wrong. I have never heard of any new engine for any make of car doing this in - my family’s and relatives cars, with my friends cars or from the Hyundai mechanics with other Hyundai vehicles.

I am continuing to battle this regarding who be responsible for the repayment of this repaired engine.

I bought my 2011 Hyundai Elantra in 2013 at a Hyundai dealership. Recently, my car started making a rattling noise when I started it up. I had an appointment to get it looked at and figured it was just a loose belt. I continued to drive it and one night I was delivering for work when it would not start! I even tried using jumper cables to start my car, but that was unsuccessful.

I had to call towing companies all over and finally managed to get it to the dealership. A few days later they called and told me I needed a new engine, which costs $4,500. I had the other option of buying a used engine, which was $3,500. Neither options were feasible for me, a senior in college who is about to graduate. When they explained the issue, they said a rod had been thrown through my engine and created the rattling noise. Metal was apparently mixing with my oil and creating a "sandpaper" like effect in my engine. I had my oil changed regularly and had just got it checked the week prior.

Apparently my car wasn't covered under the warranty even though it had less than a hundred thousand miles on it and was five years old. Long story short...I have no idea what to do and do not recommend buying a Hyundai. It sounds like this problem is pretty common, and Hyundai is not being responsible and recalling the engines because it is too costly for them. So instead they are ripping their customers off and people need to be aware of this!

When the engine is running there's a loud ticking noise constantly and grows when the RPM's rise while driving. It's beyond annoying and it seems to be mentioned here by others several times. I always stay on top of making sure the oil is in check as well as any maintainance the car needs. I'm seriously hoping that Hyundai is going to notice this issue and put out a recall on it as they should if so many people are experiencing the same problem.

I feel it's just a matter of time before the engine just dies completely, and if that were to happen while driving could be an incredibly significant safety issue.

When the car started after sitting a couple hours the upper end of the motor rattles for several seconds. This indicates that this area of the motor is being starved of oil and there is an oiling problem.

When I took if to the dealer in Ca. only to be told that it has a warranty and not to worry. My wife took it in a second time only to be told they didn't hear it. I wonder if something else is going on here in additional to the original problem.

This is metal to metal wear which is not good especially on a twin cam motor. A lot of damage is occurring.
