Genesis Reliability

I am a young car enthuist. I have beein workin my ass off to save for a nice car (always kinda had my heart set on the genesis) but trying to find good solid actually owner experience on how these cars age is difficult as google useually gives me ancient videos of the reviews, i have beein lookin at the 2010 BK1 style as its more in my price range than a BK2
If theres any guys out there that own a 2010 3.8 manual or newer let me know if this car ages well and if its a good daily driver in terms of long lasting (I dont plan on tracking the car and any mods im going to do consist of bolt ons as money is a issue and experience).

Any car will "age well" if the owner takes care of it. You'll be able to find one like that if it's clean inside and out...and have the mechanical stuff looked at by someone who knows what they're looking at.

It's funny how many beat up GC's are out there...people just beat their stuff up because they don't care enough. Mine is pristine...a little over 60,000 miles and it looks better than new. I baby the **** out of my car because it's among the sexiest looking commuter cars I've ever seen. Exotic looking without the price tag. I've been considering buying a Lotus Evora for a few years, but every time I get close to getting one I realize that I won't drive it nearly as much because I'm afraid of door dings from some ass-hat who doesn't value other people's stuff. I bought mine new in November 2013, and aside from a bit of wear & tear it's perfect. Just spring for a clear bra to avoid rock chips.

The Genesis is inexpensive to own and operate, without the fear of trashing something super expensive.

@lostpilot28 yeah I have a kia rio now as a DD lol and I baby it too because i want to keep the resale value somewhat decent i repect your choice for a lotus lol after i get a nicer sportier car be it a genesis or what ever i may get i want to get a elise or exige maybe a 600cc bike or something nice and very quick. I will probly take it for a 180point inspection when i find the right car to look at, you got any tips for buying one that maybe i can see right off the bat? other than like body damage interior damage and some engine damage like rusting or corrosion that youd find on any car. but like genesis issues like for example if the diff leaks or if the car has rusting issues on certain weak points in the chassis or mounts

Lostpilot28, small world. I discovered and ultimately purchaced my Genesis coupe new in 2014 over the Lotus Evora. Theres much to be said for daily practicality and creature comforts to go along with performance, it makes you want to spend time in the car. The price difference and future parts availability helps as well.

Hey Jesse,
Honestly, I think just the overall condition will tell you a lot. High mileage doesn't always mean junk if you pay attention to what "normal wear" is for the mileage on a car. If I were getting one used, I would just want it to be clean inside and out...not clean like a dealer just washed & vacuumed it, but clean as in zero damage. No door dings, dents, rust, worn out carpet or seat bolsters. Even things like wear spots on the arm rests would make me think twice. It's those little things that clue you in to the previous owner's level of care.

As for mechanical, service records are great, but without that just take it to someone who knows what to look for. I would never trust a 180 pt inspection from a dealer because they have a vested interest in selling you the car. Maybe a dealer that hates the dealer you're buying from. Don't just look at the drivetrain, either...suspension, bushings, wear patterns on the tires and brake discs, etc.
@lvdukerider - yeah, man...the Evora is a super sexy car, but damn if they don't seem basic as far as creature comforts. Amen on daily practicality, too...that's why I love the Genesis...you get so much more for your money, and a sexy (fairly uncommon) car that turns heads. I have zero regrets buying mine...I wonder how long I'll keep it...I'd like to think until it becomes a collector's car!

@lostpilot28 yeah I know not just to focus the diff I know a decent ammount about stuff to look for any car im enrolling next year as a technician to get my certificate. But I was just wondering if you or anyone has any pointers on the genesis i may need to look out for. ive done as much research as i can but all i see online is the same "tranny issues" but its mainly guys driving their cars like they are kimi raikkonen so its no surprise the synros for 2nd and 5th are crapping out i plan to take care of my car probably keep it mostly stock i plan on getting some coil overs as the R spec is very rare in my area and the GT seems to be the only option and probably some grippy tyres and a catback exhaust. other than that it seems to me the 3.8 does not like to be modded as most mods for it are away from the engine. their is no super charger application and 1 turbo kit ive seen.

I don't think there's anything specific to the Genesis that I would look at. Even the common complaints about transmission issues are pretty rare compared to the total sales numbers. I have the 8 speed A/T and it's pretty good, although it thinks too long before making a commanded shift. Aside from that, I haven't had any issues with mine, so just the standard things to look out for would be all I would recommend.

As for mods, I haven't updated my signature line in a long time, but I got rid of the SFR tune because it sucked. The BTR tune, full exhaust (magnaflow with headers), drop in K&N filter, and a few minor mods called out in the 3.8 section gave me 302 WHP. I imagine it would've been slightly better if I dyno'd with my lighter RPF1 wheels at that time. Either way, that's pretty respectable for a mostly stock 3.8.

Good luck, though...I hope you find a good clean one. You'll like it.

Driving style has nothing to do with it. The manual transmission is garbage straight from the factory. If you shift it at 2500 rpm constantly you may never have a problem with the syncros. But then what's the sense of having a manual to begin with. Some Bk1's have weak tensioners and timing chains as well. Another problem is the rear differential mount. Besides that...its quite reliable.

@lostpilot28 thanks for being so helpful man they are kinda rare in my area so the few i do get to choose from ill be very picky and make sure its a good car
@Genesis306 I heard that... im looking for a manual i will not buy a auto, is there a way to improve the gearbox (I heard the megan racing mount helps and a short shifter and some other mounts) or is there a better gear box i can put in to the car? any advice would be much appreciated

Fluid swap and additives. Do a search. Lots of info on here. Mine grinds going into 5th at anything over 3500 rpms. I just put the clutch in and wait a second before selecting 5th gear. Would bother me at first...but I just got used to it...so much in fact that I keep forgetting to order the additive which is said to cure it (ceretec)

Mine's been pretty good as a DD. No serious mechanical problems. Had a strange anomaly happen a couple years ago but went away on its own... think a coil bank got moisture in it or something. Seemed like only half the engine was banging for a few seconds on cold start. Never happened since. Do my own maintenance. Makes a fine daily driver and zippier than a lot of cars out on the streets. Good acceleration getting on/off freeways.

Mine has done this to me maybe 4 times in the many years I've owned it. Not sure why it does it, but I just shut down and restart. I chalk it up to the ECU being weird. Otherwise, no issues.

I definitely wish I had a manual sometimes, but that's mostly because the A/T gearing is too close together. And because shifts aren't as snappy in Sport Mode as they should be. Other than that, it's great.

Good luck, OP.

Boys; The Evora is the natural and obvious choice for non-herd-mentality GT car enthusiasts looking to step up. It also happens to be the best choice for back-country travel, and it's toyota parts bin assembly means it's likely the most reliable exotic in terms of mechanicals. They can keep their Caymans and 911's. lol

OP: The GC's reliability is kinda spotty, but more in the gremlins department than in the catastrophic failure "Total Loss" category. I have a 95k mile 2011 manual, running pretty strong. Problems include;
1 a diff whose gearing is a bit out of lash(clunky and whiney)
2 a small vacuum leak that I'm having a devil of a time chasing down. It must be a bad injector o-ring.
3 Crunchy synchros in 6th-sometimes 5th
4 Years ago, on hot days it would go into limp mode once in a while(I've had the car for nine years 6 months and it's only done that maybe 3 or 4 times, custom Dyno tune)
5 once or twice I've had a real hard time starting it- not a battery issue but probably fuel related
6 like any car, eventually the timing chain stretches out of spec. DOHC, chain driven, variable timing, direct bucket actuation valvetrains are a 3itch to fix

Everything else has been wear related, or my own stupid fault modding it. Honestly, the transmission issues aren't that big a deal. The actual gearbox will get you home, but let's just say the rebuild interval for the synchromesh system is woefully short.

The bigger issue is the diff. I could see one actually blowing up. But currently, replacement differentials are inexpensive and warning signs that you have a problem are plentiful.

To sum up, it's not a Camry, no. And replacement parts from Hyundai/MOBIS are pretty friggin' expensive, but it's nowhere near as bad as Scooby exploding ring lands, Magic disappearing RX8 apex seals, or BMW's burning through their main bearings, etc. Also, the GC is remarkably easy and accessible to work on yourself - very forgiving, there. And for the record, Mustangs and Camaros, even some G/Zcars of the same era had the same synchro problems. Looking at a 10 year old performance car, you could make a lot bigger mistakes than buying a genesis.

Over 120k on mine. It is a daily driver which is driven all year regardless of weather. I just did a complete detail this weekend. She looks better than the day I drove her off the lot. I am very anal about maintenance which is key. My wife's Elantra got a tire rotation and oil change today as well. This car is wearing like our Honda Element with over 162k miles on it. Very happy with my Gennyl

I love my 3.8 M/T 2012 GC.

got it in 2014 when it was 2 years old at 35,000 km

it now has 139,000 km just over 5 years later.

I redline it almost every chance I get, drifted a **** load when i didn't care about my tires and generally love ripping it hard every chance I get.
and all I've had to do is the normal stuff (and normally VERY late for example the brakes were not touched once until 130,000km cause there was no pad left).

I have to say it has SHOCKED me with how much abuse it has taken, all the launches, redline shift street racing, and generally driving it like its stolen, or on a race track.

No complaint for reliability here, quite the opposite.



I once read the bk1 3.8 Lamda engine was rune at some crazy amount of hours at 6.5k rpm, and then again at 7k rpm (on these forums)

I've got a 2010 3.8 I've owned since new. Not high mileage, but I've got ~140,000km on it now. Driven year-round in Ontario. Very little has gone wrong, but a few things to note:

  • Pay attention to how it shifts on the test drive. If there's any hint that the transmission isn't great, walk away. Some coupes have had issues with the tranny (check the like 200 page thread here for horror stories), and if you've got a bad one, you've got a bad one. There's some stuff you can do to make it a little better, but if it grinds or shifts poorly, there's no way to really fix that.
  • Also make sure the clutch isn't slipping. Give a good full throttle run in a higher gear. This is the type of car that encourages people who don't normally drive standard to get a standard car. A lot of noobs out there burning clutches. This goes for any 'sports' car.
  • Check for water damage, specifically in the trunk. The tail lights have a design flaw in the seal, and a lot of them leak. It's an easy DIY fix if it happens to you, but if a previous owner ignored it for a while, it's possible water sat in the trunk for a while.
  • The car has a dual mass flywheel that is known to kind of suck. If the car sounds rattly at idle, it's not necessarily a sign that anything is wrong. Mine has been rattling since new. Here's a post I made in 2011 Mine still makes that noise, and it hasn't worsened or caused any issues.



Parts I've had to replace since new:
  • Concentric Slave Cylinder
  • Serpentine belt
  • One wheel hub due to damage
  • Tail light water seal
  • Sunroof water seal
  • High beam bulbs (still on original low beam Xenons)
  • Reverse bulbs
  • Tires
  • PCV Valve (Just did it. it wasn't really dead, but they're so cheap...)
  • Battery (lasted 7 years!)

And of course, regular fluid changes in decreasing order of frequency: oil, coolant, brake, power steering, trans, diff

edit: I've also had to clean out the throttle body a couple times. It gets oiled up from the PCV and actually threw a code on me. So once every couple years now, I clean it out with some carb cleaner and a rag.
