2009 Genesis 4,6ltr Engine blown

[DanC]

Bought my Genesis new in 2010, joined the forum soon after, I had posted some issues at the very beginning but I hadn't posted anything since a very long time. I've had multiple issues some of them due to the vehicle but for the most part, issues with this vehicle have been induced by the incompetency of the dealer in servicing this model. Recently the technical advisor at my local dealership advised me that unfortunately the personnel at that dealership hadn't truly been trained to service the Genesis product line. I think that separating the Genesis range from the standard Hyundai product line and dealership network will be a welcome change, here in Canada that is.

Now to my actual reason of this post, driving on the highway yesterday afternoon, my check engine indicator came on, car started to vibrate, I first thought I had a problem with one of my tires, pulled off the highway as soon as I could, realized that one of my cylinders wasn't firing. stayed on a rural road to keep the rpm low and not cause havoc for the highway traffic. about 12km's later (+/- 8 miles) on the way to a garage, oil light came on, fluffing noise from engine, pulled off the road right away. Once stopped, noticed that oil all flushed out from bottom, result blown engine at 198000km or +/- 120000 miles. This car as always been serviced at the dealer, never missed regular oil change and was kept in pristine condition.

Have others experienced blown engine with the 4,6 litre motor?

I have 182000 miles on my 4.6 and runs great. Techs not trained properly would worry me a lot. Did you check your oil after service to verify the proper level?

I assume you mean there was no oil in the engine at that point but wondering what you mean by "all flushed out"? Was there a puddle of oil underneath the engine where you stopped or was it splattered all over the rear of the underneath?

Man, if this engine can't make it to 150K mi with the way I drive, then I will be done with this brand. Every vehicle I have ever owned (Nissan Maxima, Chevy Tahoe, Jeep GC) all made it to 200K easily.

OP, please keep us posted. Maybe the dealership didn't tighten the oil pan or filter? How long since your last oil change?

It will be really interesting to know how that happened, did something break that caused all the oil to suddenly leak out, therefore rapidly causing the engine to blow, or did it consume oil rapidly leading to it being so low on oil it blew?

I previously owned two Nissan Maximas and an Infiniti M35x that all had the Nissan 3.5 liter V6 which is one of the best engines ever made, and owners have driven cars with those engines 200K and more without problems like this.

I understand the 4.6/5.0 liter Hyundai V8 engines are supposed to be at that level of quality. Yet the last few days two posts here have said earlier Genesis models (2009-2010) have blown at high miles.

Maybe we need to be pulling out the stick regularly and checking the oil to watch out for it being low, especially with the earlier builds of the 5.0 from 2012 that are also known for the oil consumption issue.

Not to worry. Mine has over 182,000 and performs like new. My Mercedes E63 has already had to have a valve cover and gasket which cost over 800.00 and the car has just over 60,000 miles on it, warranty covered the repair.

Thanks for your reply to my latest post i.e. blown engine on my Genesis, here are some added info, this car has been taken of with kid gloves. Knowing that I was going to keep it for some time after having bought it new, it has gotten regular oil change every 8000km +/- 6000 miles, always synthetic oil, last oil change was in January of this year, engine never burnt oil.

This past Friday on my way to the office all of a sudden driving on the highway about 5 minutes from my home, the engine started shaking, it was raining but kept going until I made it to the office about 15km (+/- 11 miles) once at the office i noticed that 1 cylinder wasn't firing, I figured it was a coil pack or spark plug or maybe wiring problem due to rain. Stopped the car, call a local garage my kids have had pretty good luck with (Since my dealer is +/- competent) over the phone the owner also thought it was either a wiring issue or a coil, he told me to wait about 20 minutes or so and to try to start it, also asked me if my check engine light was on, I told him that it came on at first but shut down soon after.

I made an appointment to take it to him, it is an eight cylinder motor, running on 7 cylinders for maximum 20 minutes shouldn't have been a great deal! ? left for the garage in mid afternoon Friday, kept the rpm real low, after having driven for about 15 minutes the oil light came on, moved to the side of the road immediately, engine started to make a fluttering noise before I shut it down (within seconds of oil light coming on) I got out of the car to check my oil level, at that time the oil level was good + nice light caramel colour. I put the dipstick back in and took a few step back that's when I saw the oil just gushing out of from underneath the car.

An inspection should be done by Tuesday of this week, I suspect that the push rod broke & went through the oil pan and that's what caused the oil spill.
That's as precise as I can be for you all. The other problems I've had with the car since having bought it are:
- Degradation of the leather seats, the leather front seat covering have been replace once by Hyundai.
- During the seat repair, the technician cut my leather steering wheel with what I guess was a box cutter type knife, had to fight with the dealer to get it replaced, they also broke the plastic storage compartment located behind the front driver's seat.
- Had the dealer replace a burnt fog light, upon picking up the car notice that my front proximity sensors had stopped working, they could never get it repaired 100% correctly after that
- Metal noise form the rear of the vehicle since having first picked it up, after 2 + years of being said that there was nothing and all was normal, the general manager of the dealership returned my car to me after a regular schedule service, he asked me if I had noticed that noise coming from the rear. I laughed and told him I was advise that it was a normal noise, which he stated that he himself had a Genesis and that it was not normal. It turned out to be a linkage in my rear suspension that had been broken from the start, the dealer apologized for all of the time and other it took to take care of it.
- Had to replace most of the chrome trim on the exterior of the vehicle, the finish de-laminated from the mouldings.
- the other issues were all dealer created so I'm not bringing these to this post.

Once I started having issues with the dealer, it was a catch 22 type set up, since they kept breaking stuff, I had to return to their dealership in order to have them fix it. in 2012/13 I had to go to the dealership in excess of 20 times for the most part dealer related problems.

There has been a few recalls but all car manufacturers have those.

I was set on making this car my winter vehicle and get a "toy" for the summer, will see now what happens with the diagnostic and how much for a replacement 4,6 ltr engine. I live in the suburbs of Montreal Canada, and there have not been a lot of 4,6 ltr Genesis sold, making finding a used motor hard.

The one thing I'd like to state to all, the depreciation value of the Genesis series of vehicles is significant, that was one element I did not realized when I made this purchase, well in Canada anyway. This is something that Hyundai will have to address as they are increasing the Genesis family of products in order to compete against the Germans and the high end Japanese producers. And they absolutely need to have properly trained dealership technicians to handle that type of vehicles VS Accents and Elentras!

I have never seen or heard of a V8 engine's push rod poking a hole in the oil pan. For one thing they aren't long enough and the travel of the rod is pretty short so what would send it far enough to damage the pan? For another, the Tau engine is described as dual overhead cam so it doesn't have push rods.

 

[DanC]

Push rod going through the oil pan is what I've been told by the garage? On my end, I have not personally insepcted the vehicle but from the noise that originated from the engine compartment + how fast the oil spread on the groud soon after, it's clear that something punctured the oil pan from within.
So far no 4,6ltr engines have been found on the rebuild market in Eastern Canada, I'm located near Montreal Canada, we have found one engine available in Kansas, it's a little far from here but it is an option, the cost on that one was $5,500. Hyundai were contacted, their only option is the sale of a new engine, they are asking $18,000 Cad (+/- $14,000 US) which exceeds the value of the car. We are trying to find an engine from a possible accident vehicle, we are giving ourselves until Wednesday of this week, if by then we cannot find an engine I might just have to sell to vehicle for parts. It'S unfortunate, the vehicle is in great condition (Other then the engine that is!) Our winters are harsh up here but there is no rust anywhere on the vehicle, the inside still looks near new, it was about to become my winter vehicle while i was planning to get a "toy" for the summer. If the engine would have been a 3,8 it was have been easier to replace, but not many 4,6 have apparently been sold up here.

There were problems with the 2009 V8 engine, especially when starting the engine when cold, turning it off right away, and restarting it. Often, some of valves (or whatever) where left in the wrong position, and violent shuttering occurred on startup that bent some of the internal engine parts. Eventually that will cause engine failure in the long term. The Tau V8 was brand new in 2009, and Hyundai resolved the problem with V8's built in subsequent years. There are lots of threads on this subject.

The Lambda V6 was around for many years even before 2009 in one form or another (slightly different displacement). It would have been a much better choice for 2009 pre-owned car.

what kind of additional maintenance have you done with such high mileage?

any costly repairs?

Hyundai causes this depreciation by discounting new cars so deeply. This is the reason I will never buy another new Hyundai. They are a great used value.

Must have been a connecting rod, as these are not pushrod engines.

The documentation I have seen describes the Tau engine as a double overhead cam which does not have pushrods. It could have been another piece that broke off and became wedged between the crankshaft and pan and that might have indeed caused an immediate oil loss. But someone is wrong here - either the documentation or the garage.

 

[DanC]

Guys, I earlier mentioned "push rod" it was my mistake I should have wrote "connecting rod", it was a connecting rod that eventually pierced my oil cover.

Hyundai causes this depreciation by discounting new cars so deeply. This is the reason I will never buy another new Hyundai. They are a great used value.

Depreciation is only an issue if you don't keep your car a long time. Cars having small depreciation generally make it up in the initial price. They get you coming and going but it's like insurance - I would rather gamble that I don't have a loss than plan to have one.

Yes!
I have 131K on my 2009. I recently experienced the same condition. The car was maintained at every service interval and oil changed every 3K miles. The condition came on suddenly, I barely got the car to my mechanic. Before it ceased up only to discover the engine lost the # 5 piston through the block. I have no idea as to cause.

These are actually rare issues. It doesnt happen often I personally have not experienced any blown v8's or problematic genesis / equus . I ran into this genesis 4.6L v8 the most miles I seen on a genesis.

Yes my engine just blew at 167000.
