1 Bosch CP4.2 high-pressure pump failure (recalls 22V-767 and 23V-263)

verified How widespread: Common

How it shows up

engine stall or fuel starvation in motion, crank-no-start, rough running, low rail pressure (P0087 family)

Its other signs

catastrophic failure sheds metal debris through injectors, rails, lines and tank - the full contamination cascade
owner complaints include pumps failing again after the 22V-767 recall replacement

How to tell it apart

check BOTH campaigns by VIN before paying out of pocket - the pump and the fuel-system inspection are the free remedy
P0087/rail-pressure codes with a dying pump: check the fuel filter for metallic debris BEFORE replacing parts
metal found = the whole high-pressure side is suspect (pump, injectors, rails, lines) per the campaign inspection scope

Usual fix

replace the HPFP (recall 22V-767 / 23V-263 first - free remedy; the campaign remedy is an HPFP with improved durability per the Part 573 reports)

2 Stall / no-start reports (mixed causes: crank sensor codes, HPFP recall parts shortages, electrical)

aggregated How widespread: Occasional

How it shows up

engine stalls or shuts off in motion (often at low speed), then no-start or long-crank
stalls landing during the HPFP recall parts shortage: truck parked for months waiting for the pump

Its other signs

crankshaft-position sensor codes (P0336 family) on some trucks

How to tell it apart

pull codes before ordering: P0336 points at the crank sensor circuit, fuel-pressure codes at the pump path (see the HPFP record)
a truck parked waiting for the HPFP recall pump is a recall problem, not a diagnosis problem

Usual fix

replace the crankshaft position sensor when its circuit codes are confirmed

Order: how widespread each failure is in its record (near-universal, very common, common, occasional, rare), then the number of NHTSA owner complaints that match its keywords. Complaint counts are keyword matches, not a manual review of each complaint. A symptom listed here means the failure is documented with that sign; it is not a diagnosis of your truck.
