On the 2013-2016 Buick Enclave, many 2013-2016 Enclaves lose air conditioning because fine copper particles ejected from the rear blower motor settle on the rear evaporator and, combined with condensation, corrode it and cause pinhole refrigerant leaks. High-pressure A/C lines can also leak at connections from vibration and corrosion. Owners notice the system gradually stops blowing cold, with no obvious external cause.

Common Symptoms

  • A/C blows warm or only intermittently cold
  • Loss of refrigerant over time
  • Oily residue near A/C line connections
  • Rear A/C not cooling

How to Fix

Recover the refrigerant, replace the corroded rear evaporator (and rear blower motor if shedding debris) or the leaking line, then evacuate and recharge the system. Confirm leak source with dye/UV before recharging.

Typical repair cost:$600 - $1,500

On the 2008-2017 Buick Enclave, enclaves commonly suffer failed HVAC blend-door actuators, with the plastic internal gears stripping or the small motor dying, often after about 80,000 miles. Because multiple actuators control temperature blend, vent direction, and recirculation, a failure leaves one zone stuck hot or cold, or produces a clicking/knocking sound behind the dash. The part itself is inexpensive but labor varies widely by which actuator failed.

This issue also affects: Chevrolet Malibu, Cadillac XTS, Chevrolet Camaro

Common Symptoms

  • Clicking or knocking noise behind the dash
  • One side blows hot while the other blows cold
  • Air won't change between vents/floor/defrost
  • Temperature stuck regardless of setting

How to Fix

Replace the failed blend-door actuator and recalibrate the HVAC system. Some actuators are easy to reach; others require significant dash disassembly, which drives up labor.

Typical repair cost:$200 - $600

On the 2008-2017 Buick Enclave, the 3.6L V6 in the Enclave is known for water pump failure, attributed in part to dissimilar metals in the pump that expand and contract at different rates and eventually allow coolant to seep. Owners frequently find coolant puddling after the car is parked and may see overheating if the leak is severe. It is considered a fairly routine wear item on this engine.

Common Symptoms

  • Coolant puddle under vehicle after parking
  • Low coolant level / frequent top-offs
  • Overheating or rising temperature gauge
  • Sweet coolant smell

How to Fix

Replace the water pump (and thermostat/gasket as needed), then refill and bleed the cooling system. A relatively common, moderate-cost repair on these vehicles.

On the 2014-2020 Buick Enclave, both the 6-speed (first-gen) and the 9-speed 9T65 (second-gen, 2018+) Enclaves are prone to a torque converter clutch shudder felt as a vibration or 'chuggle' during light acceleration, low-speed lockup, or while climbing grades. On 2018-2019 models GM traced many cases to incorrect transmission fluid installed at the factory, addressing it under TSB 18-NA-091 (and PIP5608C). Left unaddressed, the shudder can accelerate clutch and converter wear.

This issue also affects: Buick Encore GX, Buick Regal, Cadillac DeVille

Common Symptoms

  • Shudder/vibration under light acceleration
  • Chuggle or jerk when transmission locks up
  • Vibration when accelerating uphill
  • Shudder around 25-45 mph

How to Fix

Per GM bulletin: flush and refill with the specified DEXRON-VI fluid (part 88862156) and reprogram the TCM with a fast-learn relearn. Persistent cases may require torque converter replacement.
