Well my 18 has almost 99K on the clock. Thus far it had a couple of failed glow plugs (early replacement under 30k on the clock) and the darn coolant heater recall done and still needs to have it redone b/c the first recall was also bad.
Other than that, fuel, DEF, and routine oil changes with grease every other change. I am only on the 2nd set of tires. I don't pull often enough and my normal day trips to and from work are under 20 miles. When it does Regen, I should drive longer distances.
Sorry I wrote injector don't know what I was thinking. Corrected.
Sorry I did not have injector failure like some, mine was glow plug failure. I edited the earlier post.
And those L5P with injector failures were all repaired under warranty. I am thinking it was a bad batch as some had 1 and some had all 8. I don't recall hearing of injector failures in the 19's and up.
