There are many elements that go into an informed purchasing decision. The quality of the dealership (or quality of the service experience if one is purchasing a car from a direct seller like Rivian or Lucid) should be one of those. In relative terms, Genesis is still a new company filling out its list of vehicles and is burdened by the history of its litigation with Hyundai franchise owners.
It would be nice if the service experience matched the quality of the vehicle. In some areas, Genesis is there matching this goal; in others it is failing. There can be bad BMW or Mercedes dealership and a good Genesis dealership. But it does appear both from national polls and from this forum (and from the BMW forum as I was active on it until I traded in my BMW for the GV60P) that the proportion of bad Genesis dealerships is significantly higher than for its German competitors. IMO one needs to research that issue just like one researches the quality of the engine on an internal combustion vehicle.
OP: you don't say where you are from. Is there viable competition in your area from Audi, BMW, Lexus, Mercedes, etc.? I am what would probably be called a super senior and this is not my first "luxury" vehicle. Every vehicle has been missing some feature that I would have liked. The absence of some of those would have been enough to make me stop right there on a purchasing decision (e.g., no HUD) while others are minor. For example, my BMW 5 series PHEV had its charging port on the driver side front fender area. I put the Level II charger on the wall of my garage next to where that charging port would be. The GV60, on the other hand, chose to put its charging port on the passenger side rear fender. Unless I back into my garage (which is a tight fit as it serves as my basement storage area because out here we don't have basements) it is in an inconvenient location. To me that is a minor con. Another, being out here in rather warm Scottsdale I would have preferred AC seats vs. ventilated seats. But, again, a minor con for me. But there are such negative factors for every car company product.
I am confident that your research disclosed that one of the advantages of the G90 over the BMW 7 series (or Mercedes S series, etc.) was price. That would be a definite plus for Genesis. Many Genesis owners stopped there and made the decision on the grounds that the price was significantly less than the price of its luxury competitors. But if one stops there, one is missing many other decision points. I made my decision to purchase the GV60P because at the time (and still) it was a unicorn: the only vehicle that met my three primary requirements: small size, luxury components (including buttons and switches for controls I might want to adjust while driving) and considerable power. BMW had a sedan that might have qualified (the i4) but its "con" was overwhelming to me: the stench arising from its front end designs. Mercedes, Audi, Lexus and
Cadillac had nothing. There were many vehicles that could meet two of those requirements but not all three.
I had very good experiences with the BMW North Scottsdale dealership. My research had not shown any major problems with the Genesis dealership but at the time it was inside the Hyundai dealership and my research had not found any major negatives from that. Since then the dealership has moved its sales functions to a high end outdoor mall and built a separate Genesis service building on the grounds of the Hyundai dealership.
I was intrigued by the fragrance feature but my research had indicated that it often did not work and even when it did, it was inconsistent. I viewed it as, for me, a con but a very, very small one. The BMW,
e.g., did not allow for adjustment of the traveling speed on the ACC when it changed color (
i.e, when one exceeded the speed limit it changed colors). Out here pretty much everyone drives over the speed limit and with very few exceptions the police don't ticket unless one is more than ten miles over the speed limit). So I like to set my ACC to nine miles over the speed limit. The BMW would let me set the speed to 9 miles over, but not the color of the speed on the HUD so as soon as I exceeded the speed limit, it changed color. My Genesis, on the other hand, lets me change the speed at which the color changes so it only changes color when I am exceeding nine miles over the speed limit. I most definitely didn't like the BMW system and prefer the Genesis system. In my internal gestalt, it was a mid level con for the BMW and a mid level plus for the Genesis. At the end of the day I had to balance out the pluses and cons for each vehicle in order to make my purchasing decision.
My point is that one needs to take a balanced view of a new car purchase. Also, since no vehicle is perfect for all of us very different drivers, it is helpful to remember the positives that got you here. You did your research so enjoy the features that made you purchase the G90. Life is short and much more enjoyable if one focuses more on the positives and less on the negatives. If, on the other hand, the negatives are overwhelming, one needs to consider trading in the vehicle or doing a "lemon law" on it. Again, I don't know where you are and whether even if there is a lemon law in your area, whether you would qualify for it. If the vehicle has been in for service 8 times for the fragrance issue, I don't see a court permitting you to successfully invoke the lemon law. But if it has been in for other issues, you might have a lemon law issue (I sold back a BMW to BMW as a quasi lemon law sale many years ago when I was about to invoke the lemon law). And if you can't invoke a lemon law statute, and you don't want or can't afford the depreciation hit, then as I said, focus on the positives that got you here.
If you spend too much time focusing on the negatives, you may never get to be a super senior.
I also would encourage you to become a member of this forum and to include your location (
i.e., city) like
@Genesiswannabee did. He specifies Connecticut as his location and I grew up there and spent some time in school there and know the weather differences between it and Arizona. The quality of the AC is critical out here but the quality of the heater system is even more important back in Connecticut. So that can temper my responses (for electric cars having a "heat pump" is an important feature and many EVs don't have it; my GV60 does have it) and make those responses more helpful.
