what it costs, and how to spot it on a test drive. Free, from Milo's research on this model.
6known failure points
6NHTSA owner complaints
3safety recalls
$4,000worst-case single repair
A twin-turbo diesel torque monster that's brilliant when healthy and a nightmare of specialized repairs when not — buy only with a fat maintenance fund and a diesel-savvy independent shop lined up.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 2 of these are rated Critical.
30k–60k mi● Watch$400–$900VERY HIGH
Swirl flap actuator / intake manifold flap failure
How to catch it: Have the shop scan for flap position codes at every oil service; catching it early avoids flap debris entering the cylinder.
Source: documented (NHTSA recall)
50k–90k mi● Plan$800–$1,800VERY HIGH
EGR cooler cracking / coolant intrusion into intake
How to catch it: Watch coolant level monthly and get intake inspected for oily/sweet residue — replacing the cooler before it cracks fully saves a tow bill.
Source: documented (NHTSA recall)
80k–140k mi● Critical$1,200–$3,500MODERATE
Fuel injector seal leaks / injector failure (piezo injectors)
How to catch it: If you smell diesel or see a slight misfire/rough idle cold, address immediately — leaking injector seals can hydrolock or foul a cylinder.
Source: multi-source pattern (AI synthesis)
100k–150k mi● Plan$300–$700MODERATE
Post-catalytic O2/NOx sensor failures (subject of recall/complaints above)
How to catch it: Confirm the extended 10yr/120k warranty campaign has been performed on your VIN — many owners are hitting this right after coverage lapses.
Source: multi-source pattern (AI synthesis)
100k–160k mi● Critical$1,500–$4,000VERY HIGH
High-pressure fuel pump wear leading to metal contamination in fuel system
How to catch it: Confirm the diesel fuel pump recall (delivery/fuel pump campaign) was completed — this is exactly the failure mode it targets.
Source: documented (NHTSA recall)
120k–200k mi● Plan$1,000–$2,500MODERATE
Turbocharger wastegate rattle / actuator wear (twin-turbo setup)
How to catch it: A rattly cold-start turbo noise that clears at idle is common and usually just wastegate slop — have it checked before it worsens into boost loss.
