what it costs, and how to spot it on a test drive. Free, from Milo's research on this model.
9known failure points
1178NHTSA owner complaints
11safety recalls
$6,000worst-case single repair
A great-driving truck with two ticking time bombs: AFM lifters and the 8-speed torque converter. Buy the right configuration and it's a gem; buy the wrong one and you'll fund GM's mistakes.
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 3 of these are rated Critical.
40k–100k mi● Plan$500–$1,200HIGH
Rear window/defroster shattering (three-piece power sliding rear glass)
How to catch it: Never turn on the rear defroster in cold weather with the glass frosted — pull the defroster fuse if you don't need it; aftermarket one-piece glass is a permanent fix.
Source: owner-reported (91 NHTSA complaints)
50k–100k mi● Critical$0–$700VERY HIGH
Brake booster vacuum pump failure (part of the massive 2014-2018 recall — verify it's been done)
How to catch it: Run the VIN on NHTSA before purchase; if the recall shows open, the dealer replaces it free.
Source: documented (NHTSA recall)
60k–120k mi● Critical$2,500–$6,000MODERATE
5.3L EcoTec3 AFM (Active Fuel Management) lifter collapse — usually cylinder 1 or 7
How to catch it: Disable AFM with a Range Technology AFM Disabler ($160) the day you buy the truck — it plugs into the OBD port and forces V8 mode, dramatically reducing lifter load.

60k–120k mi● Plan$900–$1,600VERY HIGH
Power steering assist loss (EPS module) — subject of a 2015 recall but many trucks slipped through
How to catch it: Check TSB #PIT5461 and confirm the EPS software update has been flashed — free at the dealer.
Source: documented (NHTSA recall)
70k–130k mi● Critical$1,200–$5,500VERY HIGH
8L90 8-speed transmission torque converter shudder (only on 2015 6.2L/Max Tow trucks — most 2015s are the 6L80 6-speed)
How to catch it: Do a full fluid flush with Mobil 1 blue-label (LV ATF HP) at 60k — the factory red fluid breaks down and is the root cause of the shudder.
Source: documented (NHTSA recall)
70k–130k mi● Watch$300–$900VERY HIGH
Exhaust manifold bolt breakage causing tick that mimics AFM lifter
How to catch it: Before spending $5k on a lifter job, have a mechanic pull the manifold heat shields and check bolts — this is the #1 misdiagnosis.
Source: documented (NHTSA recall)
80k–140k mi● Watch$400–$800MODERATE
Water pump weep from the front cover
How to catch it: Inspect the weep hole under the pump every oil change; a $180 AC Delco pump beats a shop bill by half.
Source: multi-source pattern (AI synthesis)
90k–150k mi● Watch$250–$500MODERATE
Front differential actuator (4WD engagement) failure
How to catch it: Cycle 4Hi/4Lo once a month even in summer to keep the actuator seal from drying out.
Source: multi-source pattern (AI synthesis)
100k–200k mi● Watch$500–$900MODERATE
AC condenser leak (soft aluminum, prone to rock damage)
How to catch it: Add a mesh bug/rock screen behind the grille ($40) — the condenser sits fully exposed.
