Engine

3.6L V6

• Timing Chain Issues
  • Description/Symptoms: Engine misfires, rough idling, check engine light, and in some cases, engine failure. Often caused by stretched timing chains due to oil degradation and infrequent oil changes.
  • Solution: Replace the timing chains, tensioners, guides, and possibly the camshaft actuators. Regular oil changes with the correct oil specification are crucial to prevent recurrence.
  • Estimated Cost to Fix: $1,500 - $2,500+
  • Recalls: None Found
• High Pressure Fuel Pump Failure
  • Description/Symptoms: Hard starting, stalling, check engine light illuminated, rough idle, loss of power.
  • Solution: Replace the high pressure fuel pump and clean any contaminants in the fuel system.
  • Estimated Cost to Fix: $800 - $1,200+
  • Recalls: None Found

Transmission

6-Speed Automatic (6T70/6T75)

• Harsh Shifting/Slipping
  • Description/Symptoms: Noticeable delays during shifting, harsh shifts between gears, slipping during acceleration, and potential loss of drive. These issues can often be attributed to valve body issues or worn clutch packs.
  • Solution: In some cases, a software reflash of the transmission control module (TCM) can resolve the issue. More severe cases may require a valve body replacement or a complete transmission rebuild/replacement.
  • Estimated Cost to Fix: $200 (reflash) - $3,000+ (rebuild/replacement)
  • Recalls: None Found

Suspension

• Strut Mount Failure
  • Description/Symptoms: Clunking noises when going over bumps, excessive movement in the front suspension.
  • Solution: Replace the front strut mounts.
  • Estimated Cost to Fix: $300 - $500
  • Recalls: None Found

Electrical

• Battery Drain Issues
  • Description/Symptoms: The battery is dead or significantly drained overnight, preventing the vehicle from starting. This can be caused by a parasitic drain from a faulty module or accessory.
  • Solution: Thoroughly test the electrical system to identify the source of the drain. Repair or replace the affected component.
  • Estimated Cost to Fix: $100 - $1,000+ (depending on the source)
  • Recalls: None Found
• Power Liftgate Malfunction
  • Description/Symptoms: The power liftgate fails to open or close properly, or makes unusual noises during operation. This can be caused by a faulty liftgate motor, struts, or sensors.
  • Solution: Diagnose the specific issue with the liftgate mechanism and replace the faulty component.
  • Estimated Cost to Fix: $200 - $800+

Exterior

• Water Leaks (Sunroof)

  • Estimated Cost to Fix: $50 - $300+
  • Recalls: None Found

Interior

• Air Conditioning Issues
  • Description/Symptoms: A/C blows warm air, intermittent cooling, or no cooling at all. This can be due to a refrigerant leak, a faulty compressor, or a clogged evaporator core.

  • Estimated Cost to Fix: $200 - $1,200+
  • Recalls: None Found

In summary, the 2014 GMC Acadia, while generally reliable, does have some common issues to watch out for. The most concerning issues are related to the engine’s timing chains and the transmission’s shifting performance, which can be costly to repair.
