The 3.5 EcoBoost launch year is the one to be picky about — get the 5.0 Coyote V8 instead and this truck is a workhorse legend

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 1 of these are rated Critical.

0k–40k mi● Watch$800–$2,500MODERATE
3.5L EcoBoost timing chain/tensioner noise and occasional turbo wastegate rattle (early production units before running changes)
How to catch it: Listen for cold-start rattle at idle; if present, get it scoped by a Ford tech before it walks the timing and get the updated tensioner if a TSB applies.

30k–70k mi● Plan$150–$3,500MODERATE
6R80 automatic transmission harsh shifting / torque converter shudder, common across V6 and EcoBoost trucks
How to catch it: Do a full fluid and filter service with Motorcraft Mercon LV at 60k rather than 'lifetime fluid' marketing — cheap insurance against converter shudder.
Source: multi-source pattern (AI synthesis)
60k–100k mi● Critical$400–$1,800MODERATE
5.0L Coyote spark plug seizing/breaking on removal due to long reach plug design and aluminum head threads
How to catch it: Have plugs removed only by a shop experienced with Coyote engines using anti-seize correctly, and never let plugs go past 100k without inspection.

70k–120k mi● Watch$300–$700MODERATE
3.5 EcoBoost charge air cooler condensation causing rough running/misfire under boost after highway cruising then stopping
How to catch it: If you get a stumble/misfire code right after a long highway drive, check for a CAC drain modification — a cheap DIY fix many owners do proactively.

80k–130k mi● Watch$200–$600MODERATE
Rear leaf spring bushings and shackle wear from towing/hauling use
How to catch it: Inspect bushings at every oil change if the truck tows regularly — cheap to replace early, annoying clunk if ignored.
Source: multi-source pattern (AI synthesis)
100k–150k mi● Plan$400–$900MODERATE
Radiator and water pump failure across all three engine options (common Ford truck wear item)
How to catch it: Replace radiator and pump proactively around 100k if original — coolant loss with no visible puddle often means a slow radiator leak.
Source: multi-source pattern (AI synthesis)
120k–200k mi● Plan$600–$1,500MODERATE
EcoBoost turbocharger wastegate actuator wear leading to boost creep or underboost codes
How to catch it: If boost feels inconsistent or you get a P0299/P0234 code, replace both wastegate actuators as a pair rather than one at a time.
