I traded in my 2016 LML at 50,000 km on a L5P to avoid the possibility of the fuel pump issue , although my GM diesel mechanic stated he had only done five pump replacements. The Bosch pump was made for European diesel which is much oilier than NA diesel. Problem is they can fail with zero notice and you are stuck wherever for at least a week while the nearest GM dealer replaces your entire fuel system (cab removal required) and then presents you with a bill for at least $12k. It’s apparently a way bigger problem in the US due to their fuel containing asphaltene molecules which destroy fuel lubricity. There’s some possible workarounds like adding lubricants to the fuel…
The other big issue with that generation of trucks is rust.
