NHTSA complaint #11269065, filed 2019-10, 10 miles

“Turbo lines leaking. My model vehicle is the same N20 engine components that were installed with the f30s in prior years. BMW had an in house recall for specific models and vins but did not include mine even though they were installed with the same issues that the previous models had. Now, the turbo lines are leaking, my car only has 85000. I shouldn’t have to pay over 3k for them to correct this.”
