Owners describe multiple distinct engine failures in the 2017 Tacoma V6. The most serious: sudden loss of all power with the ACIS intake manifold flap breaking free and traveling into the engine, requiring full teardown diagnosis. Engine stalling at low RPM below 3000, particularly during rapid acceleration for evasive maneuvers, created near-collision hazards; Toyota service acknowledged the issue but never issued the promised software fix.
Cylinder misfires and zero compression failures occurred between 101,000 and 110,000 miles, with at least one requiring complete engine replacement. A vehicle caught fire while parked at 123,000 miles. The plastic rear coolant bypass pipe leaks across many examples, risking engine seizure from overheating; one dealer quoted $2,000 to fix.
Additional failures include crankshaft position sensor malfunction causing intermittent stalling and starting issues—other trucks were recalled for this since 2017 but this model wasn't included. Owners report loud clacking from the engine as early as 9,500 miles; dealers claim it's normal. An oil filter housing cracked during service, then leaked the entire oil supply. Throughout, owners encountered dealerships refusing repairs, Toyota headquarters offering no assistance, and pervasive limp mode operation making vehicles unsafe to drive.

Across the 10 complaints that reported odometer mileage, most engine failures cluster between 18,000 and 120,000 miles, with the median around 101,000. A quarter of owners report trouble before 18,000; a quarter make it past 120,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
