1 Bosch CP4.2 high-pressure pump failure (recall 22V-406)

verified How widespread: Common

How it shows up

• hard start / crank-no-start, rough running, low fuel rail pressure (P0087 family), power loss under load

Its other signs

• catastrophic failure sends metal debris through injectors, rails, lines and tank - the full contamination cascade
• owner reports include remedy pumps failing again ~19 months after the recall replacement

How to tell it apart

• 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) - recall 22V-406 inspection scope
• check 22V-406 completion by VIN before paying out of pocket

Usual fix

replace the CP4.2 high-pressure pump (metal-free system only - debris means the full cascade; recall 22V-406/Z46 first)

2 Crankshaft tone-wheel delamination and engine stall (recalls 20V-475 / 23V-411)

verified How widespread: Common

How it shows up

• engine stall without warning (in motion), then no-start / long-crank

Its other signs

• crankshaft-position sensor codes; on some trucks the dislodged tone wheel destroys the sensor and can point at deeper crank damage

How to tell it apart

• check both campaigns (20V-475 / 23V-411) by VIN first - the software remedy is free
• stall + crank-sensor codes with an intact harness = inspect the tone wheel (flexplate side) before replacing sensors

Usual fix

PCM software update per campaign (free) - the car keeps running on the camshaft signal if the crank signal drops

Recalls and bulletins

23V-41120V-475
