The 2017 Buick Envision, GM's first Chinese-built import, came with either a problematic 2.5L naturally-aspirated four or a more robust 2.0L turbo. Early examples suffer from catastrophic engine failures on the 2.5L and chronic transmission cooling issues across both powertrains.
2.5L Engine Catastrophic Internal Failure (Pistons/Bearings)
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: severe knocking or rattling from engine block, metal shavings in oil, sudden loss of power, check engine light with misfire codes, oil consumption of 1+ quart per 1,000 miles before failure
Fix: Complete engine rebuild or replacement required. Piston skirt cracking and connecting rod bearing failures are documented. Short block replacement takes 18-24 hours labor, rebuild can stretch to 30+ hours if machine work needed. Many shops recommend used/reman longblock swap.
Estimated cost: $5,500-9,000
Transmission Oil Cooler Failure and Contamination
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: transmission slipping or harsh shifts, milky/pink transmission fluid, overheating warnings, coolant in transmission pan or transmission fluid in coolant reservoir, delayed engagement when shifting to drive/reverse
Fix: Internal oil cooler inside radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, complete transmission flush (often multiple flushes), and sometimes full transmission rebuild if contamination damage occurred. 8-12 hours labor for cooler/flush, add 20+ hours if transmission is damaged.
Estimated cost: $1,200-2,500 (cooler/flush only), $4,000-6,500 (if trans rebuild needed)
Transmission Mount Collapse
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: clunking when shifting from park to drive, excessive vibration at idle, visible engine movement when accelerating/braking, rough engagement during gear changes
Fix: Hydraulic transmission mount deteriorates prematurely. Replacement requires lifting powertrain slightly. 2.5-3.5 hours labor. Inspect all motor mounts during service as they often fail together.
Estimated cost: $350-650
Fuel Pump Failure (Subject to Recall)
Occasional · high severitySymptoms: no-start condition, engine stalling at operating temperature, loss of power under load, engine stumbling or hesitation, fuel pump whine audible in cabin before failure
Fix: Low-pressure fuel pump in tank fails. Covered under NHTSA recall 20V-490 for certain VINs—check eligibility first. If not covered, requires fuel tank drop and pump module replacement. 4-5 hours labor.
Estimated cost: $800-1,400 (if not recall-eligible)
Turbocharger Wastegate Rattle (2.0T)
Occasional · low severityTypical onset: 70,000-110,000 mi
Symptoms: rattling noise on cold start for 5-10 seconds, slight loss of boost pressure, occasional turbo underboost codes P0299
Fix: Wastegate actuator arm develops play or internal wastegate flapper loosens. If caught early, sometimes repairable with actuator replacement (6-7 hours), but often requires turbocharger replacement due to integrated design. Can limp along if boost performance acceptable.
Estimated cost: $1,800-2,800
Water Pump Leaking (2.0T)
Common · medium severityTypical onset: 60,000-90,000 mi
Symptoms: coolant puddles under vehicle passenger side, low coolant warning, coolant smell in cabin, overheating in severe cases
Fix: Water pump seals fail, often weeping externally before catastrophic failure. Timing chain driven on 2.0T—not interference engine but requires timing cover removal. 5-6 hours labor. Replace thermostat and coolant simultaneously.
Estimated cost: $900-1,400
Only consider the 2.0T with documented transmission cooler replacement and clean engine history; the 2.5L is a hard pass due to internal engine failure risk.
