most likely its related to all the stuff BMW stuffed in there on top of it thats in the way, but this is just speculation on my part, that said 2019 seems awfully young to be needing motor mounts unless its driven like a race car all the time.

Apparently they tend to go at around 60k. My Nissan went 140k and still never needed them when I sold it. Her X3 is at 89k. So better than X3 average. But still 😢.
 
I think it depends on the design. BMW and other German cars like to use an oil-damped/filled assembly. The seal breaks, the oil leaks out and mount performance degrades. See also - Lower Control Arm bushings that often do the same thing.

The joys of German over-engineering...

As far as the accuracy of the flat-rate, it really depends. When dealing with AWD vehicles, some of the mounts can be really buried and a PITA to get to. After watching this video - definitely a PITA to get to:



It should also be noted that figuring out work-arounds like the guy above used is how most techs make money. They bill whatever the flat-rate is and if they can do it faster then that's $$$ in their pocket. Keeping in mind the opposite also applies - if something goes sideways and it takes them longer than the flat rate, they don't get to charge for those additional hours. Especially here in the rustbelt where one broken bolt can turn a 5 min task into a 3-hour ordeal.

It also helps when you have all of the tools and a lift like in the video above.

is your wife one of those people who treat the gas pedal like an on/off switch? bc i could see that shortening the life(i also see alot of BMWs driven that way)

my truck is at 172k still no motor mount issues.

My son isn't going to be thrilled with the "free" X3 we just gave him with 53k miles if this is true because my wife definitely only has two speeds.
 
I had a Mercedes that needed new motor mounts while still under warranty (took them an entire week to figure out that was the issue) while I've had other cars and trucks with 300K miles on the original mounts. Go figure.
 
Sounds like your Indy guy might know it's a pain and is covering himself. The dealer just has to go by the book number, but also probably has more experience/special tools to do it quicker (and charges more).

I had a Ford technician do my F150 turbo water fittings as a side job, and he said that they loose money on almost every one since most times at least one of the bolts breaks off and the have to drill/tap to replace.

No she’s a pretty steady driver. We even have disabled the auto stop/start ignition every drive since the constant start/stop at every light is not only annoying but also (according to some threads) can shorten the life of the mounts.

Super helpful thanks. Will see what my other Indy thinks.
 
One good neutral drop.....

The center mount on the boxster needs to be replaced. Other than it needs to be pressed into the carrier, it isn't a big deal.
Of course I'll need a lift to pull it off.
