6known failure points
661NHTSA owner complaints
14safety recalls
$3,500worst-case single repair
A capable, tough-riding full-size SUV dragged down by a genuinely scary brake and power-steering reliability record — buy carefully and budget for repairs.
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–70k mi● Critical$400–$1,800VERY HIGH
Electric power steering (EPS) assist loss — steering seizes or goes heavy, often with 'Power Steering: Drive with Care' warning
How to catch it: Watch for any intermittent steering heaviness or dash warnings and get it scanned immediately — GM issued multiple recalls/campaigns for this, so check VIN for open EPS recalls before it fails on the road.
Source: documented (NHTSA recall)
40k–90k mi● Plan$1,500–$3,500HIGH
AFM (Active Fuel Management) lifter collapse causing engine ticking/misfire on 5.3L V8
How to catch it: Run quality full-synthetic oil on schedule and consider an AFM disabler (range/DOD delete) once out of warranty to reduce lifter wear.
Source: owner-reported (46 NHTSA complaints)
50k–100k mi● Critical$300–$1,200VERY HIGH
Brake booster / hydraulic brake pedal hardening, reduced stopping power, sometimes with Service Brake System warning
How to catch it: Don't ignore a firm or fading pedal — get brakes inspected at first sign, this is a documented NHTSA complaint pattern on this exact model year.
Source: documented (NHTSA recall)
60k–110k mi● Watch$0–$800VERY HIGH
MyLink/Intellilink touchscreen and electrical gremlins — random radio volume changes, door locks cycling, flickering lights
How to catch it: Try a battery disconnect/reset and demand the latest infotainment software update at the dealer before paying for new hardware.
Source: documented (NHTSA recall)
80k–130k mi● Plan$200–$3,000MODERATE
Transmission (6L80) torque converter shudder or rough shifting
How to catch it: Do a full fluid and filter service (not just a flush) every 45-50k miles, ignore GM's 'lifetime fluid' claim.
Source: multi-source pattern (AI synthesis)
90k–140k mi● Watch$600–$1,500HIGH
Front suspension wear — strut mounts, sway bar links, and lower ball joints on the heavy IFS front end
How to catch it: Have front end inspected at every oil change past 80k; clunks over bumps are early warning, not just normal truck noise.
Source: owner-reported (38 NHTSA complaints)
