4th gen (T1XX), 2019+ · 2019–present
2.7 Turbo (TurboMax) · 310 hp · 3.0 Duramax diesel · 277 hp · 5.3 V8 EcoTec3 (DFM) · 355 hp · 6.2 V8 EcoTec3 (DFM) · 420 hp
Known problems
- Critical usually from 0 mi (0 km)
3.0 Duramax transmission control-valve failure → rear-wheel lockup (2020-2022 diesel)
Symptoms: the rear wheels locking up unexpectedly while driving, traced to a failing transmission control valve
What to do: Diesel (3.0 Duramax) owners should confirm the VIN against NHTSA recall 24V797000, and the follow-up 26V083000 for trucks whose first repair didn't resolve it, and get the transmission control valve replaced.
- Critical usually from 0 mi (0 km)
6.2 V8 (L87) connecting-rod / crankshaft defect
Symptoms: sudden knocking, loss of oil pressure or abrupt engine failure caused by manufacturing debris and out-of-spec rod/crank parts
What to do: Confirm whether your VIN falls under the L87 6.2 recall and have the field remedy performed; treat any new bottom-end knock as urgent.
- Critical usually from 0 mi (0 km)
Battery positive (B+) cable arcing (2019-2020 trucks)
Symptoms: an intermittent stall while driving, or arcing/heat near the battery-to-alternator connection
What to do: If the truck falls under NHTSA recall 19V888000, have the dealer inspect and replace the B+ cable; treat any burning smell near the battery as urgent.
- Critical usually from 0 mi (0 km)
Driveshaft joint weld separation (2019-2020 trucks)
Symptoms: a sudden loss of propulsion, or a new clunk/vibration from underneath while driving, caused by a driveshaft joint separating
What to do: Have the driveshaft weld inspected under NHTSA recall 20V650000; don't dismiss a new driveline clunk as routine.
- Critical usually from 0 mi (0 km)
EBCM software disables ABS/ESC or brake assist without a warning light (2019 trucks)
Symptoms: stability control (ESC) or ABS silently stops working, or electronic brake assist is disabled — with no dashboard warning light to flag it
What to do: This shipped as two sequential recalls — a first software fix, then a follow-up correcting a defect the first fix introduced. Confirm with a dealer that the VIN has the final remedy installed, not just the initial update.
- Critical usually from 0 mi (0 km)
Front/rear brake caliper bolts not heat-treated (2020 trucks)
Symptoms: reduced braking performance, a grinding or interference noise at a wheel, or a caliper bolt breaking under load
What to do: Check the VIN against NHTSA recall 20V116000 and have the caliper bolts replaced; don't ignore a new brake noise or a pull to one side.
- Critical usually from 0 mi (0 km)
Fuel pump missing a pressure regulator (2020 trucks)
Symptoms: a fuel odor, a visibly wet fuel-pump module, or — worst case — a fire near an ignition source from an over-pressurized, cracked fuel pump
What to do: Check the VIN against NHTSA recall 19V837000 and have the dealer replace the fuel pump free of charge; don't dismiss a persistent fuel smell as normal.
- Critical usually from 9,000 mi (15,000 km)
AFM/DFM collapsed-lifter failure (V8)
Symptoms: ticking or knocking, rough idle, random misfire codes, reduced power and in severe cases a stall; a collapsed lifter can score the camshaft
What to do: Do not keep driving on a persistent top-end tick or misfire — have the deactivating (AFM/DFM) lifters and camshaft inspected promptly, since early diagnosis can save the camshaft and avoid a full rebuild.
- Worth watching usually from 0 mi (0 km)
2.7 turbo fuel-injector and oil-consumption issues
Symptoms: rough running or hesitation from incorrect injector fuelling; some engines also use oil between changes
What to do: Keep the engine software up to date (an injector-flow calibration fix was issued for early trucks) and monitor the oil level on the 2.7.
- Worth watching usually from 12,000 mi (20,000 km)
8-speed torque-converter (TCC) shudder
Symptoms: a shudder, shake or brief jerk while lightly accelerating, most noticeable at steady cruising speeds
What to do: Have the transmission fluid inspected and serviced per the shudder TSB; a full fluid flush often clears it, though a persistent case can point to a failing torque converter.
- Worth watching usually from 31,000 mi (50,000 km)
V8 oil consumption
Symptoms: oil level dropping noticeably between changes, needing top-ups to stay in range
What to do: Check the oil level regularly rather than trusting the change interval alone; on the cylinder-deactivation V8s consumption of up to about a quart per 1,000 miles is not unusual, so keep it topped up and log the trend.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the in-dash Oil Life monitor; halve for towing, heavy loads or short trips |
| Cabin air filter | every 22,000 mi (35,000 km) | — |
| Automatic transmission fluid Important | every 45,000 mi (72,000 km) | 8- and 10-speed autos; an earlier fluid/filter service helps head off torque-converter shudder |
| Engine air filter | every 45,000 mi (72,000 km) | — |
| Spark plugs | every 62,000 mi (100,000 km) | petrol only; the 2.7 turbo benefits from earlier inspection |
| Brake fluid Important | every 36 months | — |
| Timing chain (no scheduled replacement) | — | all engines are chain-driven; inspect only if a rattle or chain-stretch code appears |
3rd gen (K2XX), 2014-2018 · 2014–2018
4.3 V6 EcoTec3 · 285 hp · 5.3 V8 EcoTec3 · 355 hp · 6.2 V8 EcoTec3 (High Country) · 420 hp
Known problems
- Critical usually from 0 mi (0 km)
Electric power-steering assist loss (2015 trucks)
Symptoms: a sudden, temporary loss of power-steering assist — the wheel still turns but becomes noticeably heavier
What to do: Confirm the VIN against NHTSA recall 14V719000 and have the EPS module software updated if it hasn't been done; a heavy, assist-free steering wheel at low speed is exactly the symptom this recall covers.
- Critical usually from 0 mi (0 km)
Exhaust heat-shield plastic melting, fire risk (2014 4.3/5.3 trucks)
Symptoms: a burning-plastic smell from underneath, or visible melted trim/insulation near the exhaust — an early warning sign rather than an active fire
What to do: Check the VIN against NHTSA recall 14V007000; GM's remedy addresses the exhaust-to-plastic clearance that caused this on early-production 4.3/5.3 trucks.
- Critical usually from 56,000 mi (90,000 km)
AFM lifter collapse and camshaft damage (5.3 L83 / 6.2 L86)
Symptoms: a top-end tick or knock, rough idle, and a cylinder-specific misfire code, worsening toward a scored camshaft if ignored
What to do: The same Active Fuel Management lifter failure documented on this KB's newer T1XX generation applies to the L83/L86 EcoTec3 V8s here too — treat a new top-end tick as worth an immediate inspection rather than a wait-and-see.
- Worth watching usually from 9,000 mi (15,000 km)
A/C condenser leak
Symptoms: the air conditioning gradually losing cooling power, or blowing warm outright, from a slow refrigerant leak
What to do: GM extended warranty coverage for this specific leak on affected trucks — check whether your VIN still falls inside that coverage window before paying out of pocket for a condenser and recharge.
- Worth watching usually from 19,000 mi (30,000 km)
8-speed (8L90) torque-converter shudder
Symptoms: a shudder or vibration felt through the cabin at a steady 40-70 km/h cruise, sometimes with a harsh 2-3 upshift
What to do: Have the transmission fluid and filter changed per GM's fluid-flush bulletin before assuming a bigger fault — most cases clear with the correct-spec fluid and a TCM relearn, though a case that returns after the flush points to the torque converter itself.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the GM Oil Life Monitor; halve the interval for towing, heavy loads or mostly short trips |
| Cabin air filter | every 22,000 mi (36,000 km) | — |
| Automatic transmission fluid Important | every 45,000 mi (72,000 km) | 6L80 (2014-2015 across the lineup, and the 4.3 V6 throughout); 8L90 arrives standard on the 6.2 for 2015, extends to upper 5.3 trims by 2016 and is standard across the 5.3 lineup from 2017 — an earlier fluid/filter service helps head off torque-converter shudder |
| Engine air filter | every 45,000 mi (72,000 km) | — |
| Transfer case & front/rear axle fluids | every 45,000 mi (72,000 km) | 4WD trucks only |
| Spark plugs | every 98,000 mi (157,000 km) | the EcoTec3 V8s tolerate long-life iridium plugs on this interval; inspect sooner if you tow often |
| Coolant (Dex-Cool) Important | every 149,000 mi (240,000 km) or 60 months | GM's long-life Dex-Cool; don't mix with a different coolant type |
| Brake fluid Important | every 36 months | — |
2nd gen (GMT900), 2007-2013 · 2007–2013
4.3 V6 Vortec 4300 · 195 hp · 4.8 V8 Vortec 4800 · 302 hp · 5.3 V8 Vortec 5300 (AFM) · 315 hp · 6.0 V8 Vortec 6000 (Vortec Max, 2007-09) · 367 hp · 6.2 V8 Vortec 6200 (LTZ) · 403 hp
Known problems
- Critical usually from 40,000 mi (65,000 km)
AFM lifter collapse and camshaft damage (Gen IV 5.3/6.2)
Symptoms: a top-end tick or knock that gets louder with RPM, a rough idle, a cylinder-specific misfire code, and in a neglected case a scored camshaft or spun bearing
What to do: Don't drive through a new top-end tick hoping it clears up — a stuck Active Fuel Management lifter grinds the camshaft lobe instead of rolling on it, and catching it early is the difference between a lifter/cam job and a short-block rebuild.
- Critical usually from 99,000 mi (160,000 km)
Frame and underbody corrosion
Symptoms: visible rust on the frame rails, crossmembers or along fuel-line mounting points, in severe cases enough pitting to compromise a jacking point or mounting bracket
What to do: Inspect the frame from underneath every winter in a road-salt climate, not just at inspection time; surface rust is cosmetic, but flaking or pitted rust at a jack point or control-arm mount is a structural concern worth having checked before the truck is driven or loaded further.
- Worth watching usually from 31,000 mi (50,000 km)
5.3 V8 (LC9) piston-ring oil consumption
Symptoms: the oil level dropping well below a quart per 1,000 miles between changes despite no visible leak or smoke, sometimes ending in a knock if it runs low unnoticed
What to do: Check the dipstick every fuel stop rather than trusting the change interval, especially on an aluminum-block flex-fuel 5.3 built after February 2011; a persistent, worsening trend is the piston-ring wear pattern this generation is known for, not routine break-in consumption.
- Worth watching usually from 99,000 mi (160,000 km)
4L60E automatic transmission wear
Symptoms: a flare or slip between 2nd-3rd or 3rd-4th gear, delayed or harsh engagement into Drive or Reverse, or a shudder from the torque-converter clutch
What to do: The 3-4 clutch pack and TCC solenoid are this transmission's known wear points; a fluid and filter service on schedule slows it down, but a truck already flaring under load is worth a transmission-shop diagnosis before the failure becomes a full rebuild.
- Good to know
Cracked or warped dashboard
Symptoms: visible splits or bulging in the dash pad, usually along the defroster vents or above the gauge cluster, worse in hot climates
What to do: Cosmetic and slow-developing rather than a safety fault — NHTSA reviewed the owner-complaint volume on this generation and did not find grounds for a recall. A dash cover or aftermarket replacement is the usual practical fix.
- Good to know usually from 50,000 mi (80,000 km)
Erratic fuel gauge / fuel-level sending unit
Symptoms: the fuel gauge jumping around, reading empty with fuel still in the tank, or a check-engine light for a fuel-level-sensor code
What to do: A worn or contaminated sending-unit contact is the usual cause; it's an inconvenience rather than a safety issue, and a sending-unit or fuel-pump-module replacement clears it — confirm with an actual fill-up before assuming the tank is really empty.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the GM Oil Life Monitor; treat 12 months as the backstop and halve it for towing, plowing or mostly short trips |
| Cabin air filter | every 22,000 mi (36,000 km) | — |
| Automatic transmission fluid Important | every 45,000 mi (72,000 km) | 4L60E across most of the range, 6L80 on 5.3 crew-cab trucks from 2009 and on the 6.2; service sooner if you tow regularly |
| Engine air filter | every 45,000 mi (72,000 km) | — |
| Transfer case & front/rear axle fluids | every 45,000 mi (72,000 km) | 4WD trucks only |
| Spark plugs | every 98,000 mi (157,000 km) | petrol engines only; the AFM-equipped 5.3/6.2 load-cycle their plugs harder, so an earlier check doesn't hurt |
| Coolant (Dex-Cool) Important | every 149,000 mi (240,000 km) or 60 months | top up with Dex-Cool only — mixing coolant types is a common cause of intake-manifold-gasket corrosion on this generation |
| Brake fluid Important | every 36 months | — |
