Dealer had better fix this!

[Koz]

I took my Genesis Coupe in to be serviced today. I needed new brakes all around, a tune up, and a new head gasket. It took forever to get it done and I got out of there just after their normal closing time of 5 pm.

 

The car head been misfiring a bit before the repairs, so on the way home I wanted to open it a bit and see if the old pep was back. Oil temperature was perfect, cruising at 60 mph and 1,800 RPM and I punch the gas. Tach jumps up to 4,200 RPM's and the turbo is not kicking in properly. The gauge shows boost but I'm not accelerating quickly. I normally jump from 60mph to 80mph in less than 2 seconds. I didn't crack 75 in 5 seconds.

 

So I back off and try again, this time keeping on the accelerator. I red lined the tach and still hadn't hit 80 mph. I have NEVER red lined before. Normally I'm 60 to 100 in a heartbeat. So I get on the phone and of course the service department is closed.

 

I spent 5 hours there today and now I'll have to go in tomorrow. They had better not give me the run around. I used them once before for some new tires and they screwed up the camber and toe in and I lost that riding on rails feeling when cornering. These guys aren't my normal dealer as I have moved since then. So far I'm not impressed.

wow.   I didnt take you for the Fast/Furious type.

 

head gasket?   I can't even begin to armchair quarterback diagnose this one.  good luck!!

You might want to let that gasket get good and seated and broken in before stomping on it. I don’t know if this is even true but it seems somewhat logical. 80 mph is out of my comfort zone haha

Is your hyundai an automatic tranny?  red lining and car not moving along proportionally could be the tranny oil pump. Hyundai has a recall on it automatics.

That's great to know. Thank you.

 

I spent another 4 hours at the dealer today and they told me the problem was my car needed "better spark plugs" than the one they put in yesterday. Really? After 4 hours?

 

I asked them to discount what they charged me yesterday since it seems to be their issue and they refused. I was polite and told them I would call Hyundai USA and ask them to take care of it. I told them if the problem persisted on my way home I would turn around and come back.

 

So on my way home, I accelerate and the same thing happens - more red line. But at this point I have zero confidence in the dealership, so I just called them and let them know and asked them to call Hyundai for some ideas. I needed to get to work, but said I could bring it back in the morning.

 

So as I'm driving to work I'm thinking it might be the blow off valve adjustment, a broken turbine fin, oil starved turbo, exhaust blockage, and more. 

 

But on the way home I tried something - I took it out of automatic mode and tried the bump shifter and the paddle shifters and I did not have the same problem. So this seems to match perfectly with what you said. Ah - just checked - that's on 2021 and 2022 select models and mine is a 2013.

 

So it is probably some sort of electronic control module issue, but it's very odd timing that this happened when I got the vehicle serviced. It did not happen on the way out there and I did hot foot it a bit.

When I was much younger I raced Legends cars and Late Models for a little bit. Years ago I did a few SCCA events with me Genesis Coupe.

 

While I like speed, in a passenger car I NEVER try and take the car to its limits on the street. My car is set up pretty tight and I've got some wide, soft summer tires that can be pushed a little more than your average tire. I did a track day on Roebling Road one time (helmet, fire suit, racing shoes) and hit 140 mph (and quickly backed off) in my Genesis. That was thrilling and scary. Once was enough.

 

One thing that I always wanted to try was rally car racing, but never found an opportunity. I was relegated to doing it on my PC.

Thats when i would have grabbed my keys and gotten the heck out of there. The spark plug excuse is the solution they give to unsuspecting unknowing car owners.

The service manager on up may have told the tech to pull a wire or such to cause the problem to get you back into the shop and rip you off. Did you ask if they scanned the computer? thats the first thing the tech would do to check for codes, the tech could have scanned it and purposely screed up your tranny.

 

Drop by a NAPA or auto zone or any big parts store and they will go out and scan your car for free, I did it 3 months ago.

I went to an O Rileys for my honda and asked them to scan it and they grabbed their scanner and plugged it in and in 10 seconds found out my egr valve was not closing.

It was dumping burned exhaust back into the intake making it run rough. So i bought a $5.00 gasket from them, went home and pulled the egr, decarboned the valve that electronically opens and closes and havnt had a problem since.

Rally! My youth was spent racing friends up and down dirts roads at very dangerous speeds mostly sideways. Always liked rally racing.

I raced stock cars for years, street stocks to limited late models. Like you and @Koz, I've always liked rally racing and would have loved to give it a go.

I like to watch rally racing, but never want to be in the car. Those guys are nuts.

If somebody would pay I'd play.

I informed the dealer of my findings but didn't have time to take my car back once again. It's a 40 minute drive and I wasted enough hours out there this week and I really need to get some work done.

 

Their top tech guy is on vacation next week, so I'll have to wait another week. In the meantime I'm driving around in manual transmission mode. It's not bad, but with an 8 speed it's annoying to have to jump that quickly through the first three gears after coming to a stop.

 

Funny thing though - occasionally I find my left foot looking for a clutch pedal!

 

Sometimes I miss having an old style, manual transmission car. But today's on board computers are so good even the supercars are using automatic transmissions.
