The 2017 Tundra is a body-on-frame truck built on Toyota's mature full-size platform with proven drivetrains, but the 5.7L V8 has critical piston/ring issues that can grenade motors, and transmission cooler failures are increasingly common as these trucks age.
5.7L V8 piston/ring failure and crankshaft bearing wear
Occasional · high severityTypical onset: 80,000-150,000 mi
Symptoms: excessive oil consumption (1+ quart per 1,000 mi), blue smoke on cold start or acceleration, rough idle with metallic knock, check engine light for misfire codes, low compression on cylinder testing
Fix: Full engine rebuild or shortblock replacement required—pistons, rings, bearings, and typically rod bearings all need replacement. At minimum 20-30 labor hours for shortblock swap, more if heads need work. Some shops go straight to reman long-block to save comebacks.
Estimated cost: $5,500-9,500
Transmission oil cooler line failure and coolant contamination
Common · high severityTypical onset: 100,000-180,000 mi
Symptoms: pink milkshake fluid in transmission (coolant mixing with ATF), transmission slipping or erratic shifts, sweet smell from transmission, overheating transmission temp light, coolant loss with no external leaks
Fix: Replace transmission cooler assembly inside radiator, flush transmission and cooling system multiple times, often requires full transmission rebuild if contamination went unnoticed. Cooler replacement alone is 4-6 hours; if trans is damaged, add 12-18 hours for rebuild.
Estimated cost: $800-1,200 cooler only; $3,500-5,500 with transmission rebuild
Hydraulic power steering pump failure and rack leaks
Occasional · medium severityTypical onset: 120,000-180,000 mi
Symptoms: whining or groaning noise on turns, hard steering especially when cold, fluid leaks below engine or at rack boots, steering pump reservoir constantly low, jerky or notchy steering feel
Fix: Pump replacement is straightforward—2-3 hours. Rack replacement is heavier work at 5-7 hours due to size and weight of Tundra components. Toyota issued recall 19V-854 for specific pump assemblies; check VIN eligibility first.
Estimated cost: $450-750 pump; $1,200-1,800 rack
Exhaust manifold stud failure and cracking (5.7L)
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: ticking or tapping noise from engine bay, louder on cold start, exhaust smell in cabin, visible soot around manifold flange, check engine light for lean codes or O2 sensor faults, loss of power under load
Fix: Studs break and manifolds crack due to heat cycling. Requires manifold removal, drilling broken studs, retapping, and often manifold replacement. 6-9 hours per side. Both banks often need attention eventually. Use upgraded studs on reinstall.
Estimated cost: $1,200-2,200 per side
Secondary air injection pump failure
Common · low severityTypical onset: 80,000-130,000 mi
Symptoms: check engine light with P0410 or P0418 codes, loud buzzing or rattling from engine bay on cold start, rough idle first 30 seconds after start, emissions test failure
Fix: Air pump seizes or check valves fail. Pump replacement is 2-3 hours; often combo pump and valve job. Not critical to driving but will trigger CEL and fail emissions in states that test.
Estimated cost: $650-1,100
Transmission mount collapse
Common · low severityTypical onset: 70,000-120,000 mi
Symptoms: clunk when shifting from park to drive or reverse, vibration through floorboard at idle in gear, excessive driveline movement visible when rocking truck, harsh engagement into gear
Fix: Rubber transmission mount deteriorates and collapses under weight of heavy 6-speed. Replacement is 1.5-2.5 hours depending on access. OEM mount strongly recommended over aftermarket for longevity.
Estimated cost: $250-450
Buy a 4.6L if you don't tow heavy, or budget $3K-8K reserve for eventual 5.7L engine work—otherwise solid truck with typical high-mileage wear items.
