Complaint : Knocking on acceleration
Cause : Cylinder 4 rattling under load
Correction : Short block replacement
Mileage : 31,332 km
Now waiting for short block to arrive for replacement. I had to provide proof of maintenance (oil changes) as I don't go to the dealer. Had all the paperwork in the car and Hyundai OK'd the replacement.

If it has to do with some type of coating flaking off ,I can not figure out why they put a coating there in the first place , unless it was to reduce friction. The only effective place to put it then would be on the piston block wall . But, why the knocking sound?....knocking sound always indicated to me some type of oil starvation. It is still a mystery and until more info is forthcoming it just a guessing game .

The sound is coming from the piston slapping against the cylinder wall from excess play from missing coating on piston. Once piston/cylinder wall heat up and expand noise goes away.

I'd like to see a Blackstone report from a car making knocking noises.

I've never been interested in paying 25 bucks just to see how long I can prolong the next oil change, but as a "reality check" when the car is about to go off-warranty, or when you're facing other major repair decisions, it's a great idea.

Most North American Elantras come from Alabama. Korea only handles the overflow.

Why is this a predominantly Canadian issue? My guess is a combination of sales volume + maintenance habits + climate. We Canucks buy a lot of Elantras - it's our #2 selling car right behind the Honda Civic - and we are not nearly as religious as Americans about maintaining them. And the climate, well, google it.

I agree the climate up there is rough on a car, big time. Down here we have different problems, extreme heat (torture at times) and roads that are so "holy" you can take them to church.

In the first 5-7 years of the car's life, I expect the extreme cold to cause more problems on these cars. Do they put lower temperature rated fluids in the vehicles sold North of the border? The stock fluid in the windshield wipers froze the first time It saw -4C outside. But surely you have to add more antifreeze up there? In all seriousness it does suck that even with all the snow and ice and how that takes a toll on the car's body they (Hyundai) didn't make an engine that could outlive the body. I know a few ancient Honda that look like shitbuckets, and could probably outrun me on the highway. (I don't do racing, unless you want to race to 40MPG)
