If you're not BMW fanatics, then I can't imagine why calling one part
on the car crap sets off this hostility. And IMO, those tanks and
the window regulators are crap.
If you search through this forum you will see lots of
people with failed tanks, including cars at well under 100K miles. In
every other vehicle I've had, I've never seen a single coolant tank
failure. And you also have many people here that have gone through
more than one tank too. It's 2015, we have modern, tough plastics
and it's simply unacceptable to have expansion tanks that crack
frequently. As long as you keep accepting it and saying it's perfectly
OK, then BMW has no reason to fix it. The same is true of their
window regulators.
Then you digress. I didn't say the X5 is "full of junky parts". I
specifically identified the tank and a few other parts as being crap.
But since you want to discuss the overall vehicle reliability, here is
what JD Powers says in their 2015 study:
2015 Vehicle Dependability Study (VDS) by Category | J.D. Power Cars
The X5 shares the lowest reliability rating on the list, 2 stars, while
the best SUV has 5 stars. Presumably they use real data and are not
out to lie and screw BMW. I could show you more too, but too many
folks on here just can't stand the facts.
