Known problems
- 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 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 |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
