2015 Genesis break-in period

[Alwaysforward]

Someone here posted that it was 600 miles. Can anyone direct me where this is in writing?

I feel sorry for those cars that get revved so high during the test drive process.

 

[darthspader]

its not that big of a deal if they do. read first sentence. " there is no special break in procedure." the it states "you MAY improve performance etc.." if high reving a car a test drive did damage to the car then it wouldnt be allowed. just my opinion.

There is a break-in procedure. Try and keep the engine running between 2000 and 4000 RPM.

Depends what you mean by damage. The reason for a break-in period for the engine is to ensure the piston rings "seat" properly. If rings don't seat properly, excess oil consumptions and/or poor fuel mileage may plague the engine for its entire life. Pistons may not seat properly during the break-in period if the engine is either run at too low of a RPM, or too high of a RPM, causing less than optimal engine wear between the piston rings and cylinder walls. There is little doubt that if someone pushed the engine to redline for extended periods right after assembly that less than optimal piston ring seating is more likely to occur. But engines are usually run for some period of time before any customer starts it.

Modern engine manufacturing techniques make engines less susceptible to break-in problems than was once the case, although a fair number of the early 2012 Tau 5.0 engines had this problem even when proper break-in was followed (as documented by many on this forum). Hyundai fixed the problem with a manufacturing line change at some point (and had to replace a lot of engines).

There is a also a break-in for brakes (any time brake pads/rotors are new), but at least if they are messed up, it doesn't cost that much money to replace them.

like i said not that important. to break in brakes you are supposed to slam on them suddenly, but everone thinks you are supposed to take it "easy" on the brakes.

 

[darthspader]

plus im sure before the engine is ever mounted on the car chasis it was "broken in"

Did you read the break-in procedure link above? What you said is exactly opposite to what the procedure is, for Hyundai or any other brake system.

The engine is tested, but not completely broken in as would occur during first 600 miles of driving. Did you read the Hyundai break-in procedures posted above?

 

[darthspader]

yes i did did you. first sentence says there are no break in procedures. everything after that is for your piece of mind.

What

 

[darthspader]

What

yes look it up its call brandishing brakes.

 

[Mark_888]

yes look it up its call brandishing brakes.

That is not what Hyundai recommends. If giving advise to others, it is probably a good idea to only quote authoritative sources, such as documented in the Hyundai Genesis Owner's manual.

 

[darthspader]

you are right i started this conversation with imo. i am stating just from my experance only. i do not belive what i read. in no way and if i did i applogize try to pass my opinion off as fact. its just how i maintain my cars and i have never had an issue.

mine didnt say anthing about brakes? did your?

 

[PMCErnie]

You probably mean burnishing, not brandishing. But Hyundai doesn't recommend it in any case. The concern is the possible warping, or gouging, of the rotors.

Also, I doubt that Hyundai is trying to give customers "peace of mind." What they are doing is cautioning against thrashing a brand new car before some of the critical moving parts have had a chance to get know each other.

Yes, all Hyundai Owner's manuals have had the same (or similar) instructions as Ernie3647 posted above in his attached jpg:

"Avoid hard stops, except during emergencies, to allow the brakes to seat properly."​

The above applies to the 600 mile beak-in period.

My 2010 4.6 genesis cruises at 50mph @ 1600 rpm and 70mph@1900 rpm. How are we supposed to break it in between 2K and 4K rpm?
