    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

So my G70 sunroof exploded on the highway today. #&@!

Although the failure of my sunroof glass was probably due to a defect, I was curious about the glass thickness, and how it compares to other cars. I measured the thickness of a piece of the broken G70 glass to be 3.80mm. By comparison, the glass thickness on my wife's CX-5 sunroof, which is much smaller, is about 3.5mm (my measurement might not have been quite as accurate because I didn't have the "luxury" of a broken piece to measure).
I tried Googling to see if I could find data for the thickness of other manufacturer's sunroof glass, but wasn't able to find much. If anyone has some data, chime in.
Sorry, once an engineer, always an engineer, lol.
 
Does this change your view on keeping the car based on the overall experience?
 
I'm undecided. I still really like the car, but I'm really disappointed in the lack of support from Genesis, the apparent lack of parts and the lack of well-trained techs to work on them (at least around here) when something goes wrong.
I've spent quite a while trying to figure out what I'd replace it with. My first choice is probably an S5 Sportback, but then I'm going to have to shell out another $30k-$35k to pay for it. As a retired guy, it's hard to justify. Another choice would be a certified M340i, but I haven't been able to find any.
I had thought I might take this opportunity to get my first EV, but the choices are limited, and many (like the i4) don't qualify for the tax credit.
As an old girlfriend used to say, "not to decide is to decide", haha.
 
It sucks the Genesis experience is so hit and miss in the USA... Seems to be the opposite up here in CDN. With my lease coming due, I started looking for something else as well. M340, S5, C43.. the Lexus IS500 really caught my eye but the test drive was a bit disappointing... After checking out all of those cars, I drove a 2023 G70 and was sold. Go figure. I just think the car hits all the buttons for me. I should get it soon!
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!
Glad they've got their act together better in Canada. Congrats on the new G70 order. When I was at the dealer to talk about my roof, there was a beautiful new red 2023 G70 Sport on the lot. It was tempting.
What trim and color are you getting?

That red looks amazing

Top trim in Canada. AWD Sport. It has every feature.

Makalu gray with red interior
 
Ooo, nice. The red interior is really good looking.

It's not hard to be disappointed at Genesis in your situation. Don't blame you for looking for a different car/mfr. However, it would be good to evaluate options at the 5,000ft view, instead of dwelling on a single incident, however inexcusable it might be.

German alternatives certainly seem appetizing. Their dealership experience probably are levels above Genesis's building-attached-to-Hyundai-dealership. I myself was a big German car fanatic back in the days, but over the years, I grew less and less enamored, to the point where all the top-notch German engineering just aren't worth their expense and unreliability, if I'm keeping the car for yrs past factory warranty. Vast majority of luxury German cars are leased and traded in on a newer one. For that, I have no doubt ownership experiences can be exemplary. Long term though, German cars are nowhere near as reliable as their asian counterparts. It is no surprise that resale value of the typical German luxury car drops precipitously not long after warranty expires. Not just that... talk to any mechanic who wrenches for a living, and they'll tell you Germans cars are their least favorite cars to work on, by a wide margin.

I have not leased a single car... ever, and probably won't any time soon. Nothing wrong with that if the terms fits the car buyer's needs, but it just doesn't suit how I operate. A lot of you know from my posts here how I like to tinker on my cars. That wouldn't work on a lease car. For me, how a car is to work on is just as important as how it is to drive. On that scale, based on my own experiences, I would rate them in order of preference: Korean>Japanese>American>>>>German. Drive a car, and you can peek into its engineers' mind. Wrench on one, and you pierce into their soul.

Right now, the only German machine I have is a K1600GT. While it is generally quite reliable so far, the little bit I've worked on it have revealed enough WTF?! things the boggled my mind why on earth they would do thing like that. It's enough to keep me from buying any German car. At least until one comes along that might be worth putting up with all the WTFs.
 
I understand. It is good not to let one bad experience (depending on how bad it is, lol) overshadow everything else.
I agree with some of your points regarding German cars, and even high-end/premium/luxury cars in general. The crazy high cost of after-warranty repairs has driven many people (not me) to leasing or selling the car after it's out of warranty. Hell, a headlight assembly these days is like $2000!
However, as I've mentioned before, maybe I was just lucky, but my 2006 330i with 80k miles and 2011 335xi with 65k miles (so both out of warranty) were both extremely reliable. I wouldn't have been afraid to keep either of them much longer than I did. I sold one because I decided I wanted AWD, and then I sold the other when a loaded sport model with a manual became available. The biggest issue I have with BMW now is their styling. I don't like their looks or their new dash/gauge layout.
Bear in mind that when we find WTF things with any car, it's just as likely to be the fault of a bean counter as it is an engineer. We aren't privy to the internal struggles between departments within a company while a product is being designed, but my son and I have both witnessed this first-hand. Marketing/Sales usually wins. Having said that, I will say that companies like Toyota have a leg-up on reliability over most companies, including the Germans. At the risk of stereotyping, I would say, having worked with them, that the Japanese put a very, very high priority on good design and reliability. And they are extremely demanding of their suppliers. It's cultural. When I worked in aerospace, our president hired a Japanese quality guy from Toyota. Word got out that when our president was proudly showing off our latest production facility, the man made a comment to the effect of "they couldn't build radios for Toyota". Our suit wasn't too happy, haha. For some interesting reading, google W. Edwards Deming and Japan.
By contrast, it would seem that the Germans may focus more on performance, perhaps at the expense of reliability.
I haven't figured out where the South Koreans stand yet (other than providing high value to try and take customers away from established competitors).
 
Yeah, Deming is well known by anyone who has worked extensively in engineering and mfg in the past 30+yrs. IMO, lots of companies still don't get it right. I remember a company I used to work for tried to implement Continuous Improvement and Kaisen principles, While they did make some good policies at the shop level, they were clueless on what that should mean for the engineering level. They instituted policies on how many pens, erasers, notepads, etc., each engineer should keep in their drawers, how many poster we can put on our walls, how many coffee runs and toilet trips per day, and that sort of nonsense. All in the name for efficiency. Absolutely moronic. Of course, most of us just went... yeah right, and disregarded it all. It's about as Dilbert/Dogbert as it gets.

Anyhow, about German engineering... I was so intrigued by it back in my school days I actually took German for 3yrs, both in HS and in college, to better understand German culture. Much like Japan, a lot of their engineering prowess is imbued with many of the idiosyncrasies of their cultural identity and spirit. When I was in grad school, I had a German exchange student as a housemate. When he first moved in, he found the desk to be much too low for his stature, being some 6ft 2 or 3. I told him, hey... no problem, I've got some leftover 2x4s in the garage, we can just cut a few sticks to fit, and he'd be good to go. He thought about it for a sec, then looked around the kitchen, and picked up a whole bunch of aluminum coke cans we had in our recycling bag. I help him bring all the cans up to his room, lift up the desk and placed rows of coke cans under the desk. Voila! Perfect height for him. Not at all what I would've done, but, it did the job.

About my K1600GT... the engine is a marvel of engineering. An inline6 that is turbine smooth, but not much wider than the typical inline4 engine found in that class of sport touring motorcycles. It had a rather peculiar "dry" sump system. Instead of the separate oil reservoir, BMW incorporated it into the engine block, stacked under the crankcase oil pan. So... in order to drain both sumps, you'd first have to remove the drain plug to the lower sump, and let the oil drain out. Then you insert a long hex bit in through the drain pan to remove the drain plug to the inner sump. Sounds easy enough, but the whole affair just turns into a big oil mess, no matter how you try it. And it doesn't help that the BMW engineers spec'ed a hex head on the inner drain plug that was wayyy too shallow, which made it difficult for the hex bit to grab, especially when it's drenched in engine oil. The whole debacle actually spawned an aftermarket for modified inner drainplugs, to make R&R easier.

From an engineering POV, that design is rather ingenious... reducing component count and overall weight. However, from the POV of person having to service it, it is an absolute nightmare. I see it from both POVs, and I'm sympathetic to both. It's the kind of WTF that makes mechanics despise engineers.

I can see where that oil drain plug would be an issue for the customer. I think the Germans would just say that's the price you pay for performance and their ingenious design.
Sounds like we have similar backgrounds. The aerospace company I worked for also pushed "continuous improvement" and TQM for years, and spent tons of money on off-site training, posters, etc..., but totally missed the real point of it and didn't make any meaningful changes. It was one long Dilbert cartoon for sure.
 
Driving on the highway today, at about 75mph in rush hour traffic, with my sunroof closed. It suddenly just explodes! It was a mild 50 degree day, so no thermal stress. I wasn't driving under any overpasses, I don't believe anything hit it. Sounded like a bomb went off.
I pulled over at a rest stop and tried to clean it up a bit and break off most of the cracked glass that was left. I had to drive two hours on the highway to get home, with the sun visor/headliner open part way because it was buffeting so violently with no glass to cover it. Got glass all over the interior. What a mess!
I called Genesis right after it happened (even though I'm out of warranty). They opened a case, for what that's worth. I'm not sure if they're going to cover it. It's going to be pricey. I'll talk to my insurance agent tomorrow. Argh. Not feeling too good about this.View attachment 51775

This just happened to me today, with my 4 year old son in the back seat! It's about 45 degrees here today, and I was driving about 75 as well. I thought a bomb went off too, and the glass cut my sons hand....it was so scary. Nothing in front of my and no other cars around so it was completely random. I was able to exit off right away and got help but I could no believe this happened!
 
This smells like a class action coming soon. All it would take is some lady driver that gets startled by the exploding sunroof, flicks the car out of control, and causes an accident with serious injuries or fatality.

All I can say is get yourselves dashcams that records front and back, preferably 4k.

OMG, sorry to hear that. This is crazy, and I expect will continue to happen to others.
We do need a class action suit, although I imagine the number of failures is relatively low. (Not that that matters much once it happens to you!) Any lawyers here??
Is your car still under warranty? If not, don't expect any support from Genesis. The good news is the glass can be replaced pretty easily, quickly and cheaply (if you have glass coverage anyway).
Any pics?
Good luck and keep us posted.
 
G80 2021 glass piece between the panoramic and windshield exploded and shattered....so the problem is still there. Why in the world that piece is made out of glass!!!! Also, now that I checked there is the same glass piece between the rear window, too.
Does anyone know if this is or should be covered by their bumper-to-bumper warranty?
 
Didn't the Genesis extend warranty over those problems with pano roofs?
Hello sir I have a question about your Lazic tune. I realize this isn't the right thread for that but I also didn't see a way to msg you directly. I went to Lazics website and it's pretty bad and not functional. Any info you can provide on your experience is greatly appreciated.

send him a message thru Instagram he's quick to respond, i just ordered a TCU from him
 
Thank you so much I tried a search and didn't find it initially. Appreciate you
