2015 Chevrolet Traverse

The 2015 Chevrolet Traverse is a popular full-size crossover SUV known for its spacious interior, comfortable ride, and ample cargo capacity. It’s a family-friendly vehicle that many appreciate for its seating for up to eight passengers and relatively smooth highway driving. However, some common complaints revolve around its large size making it less maneuverable in tight spaces, and certain model years are associated with specific mechanical issues that can be costly to repair. The 2015 Traverse came standard with a 3.6L V6 engine producing 281 hp and 266 lb-ft of torque (or 288 hp and 270 lb-ft in the LTZ trim due to dual exhaust), paired with a 6-speed automatic transmission.

Symptoms include a rattling noise, especially upon starting the engine, and the check engine light illuminating with codes related to timing discrepancies (e.g., P0008, P0016, P0017). This can lead to poor engine performance, reduced fuel economy, and eventually engine damage if left unaddressed.
  • Solution: Replacement of the timing chains, guides, tensioners, and potentially the camshaft gears.
  • Estimated Cost to Fix: $1,500 - $3,000+
  • Recalls: None Found
• High Pressure Fuel Pump Failure
  • Description/Symptoms: Experiencing hard starts, extended cranking, reduced power, or stalling. A check engine light may illuminate with codes related to fuel pressure.
  • Solution: Replacement of the high pressure fuel pump.
  • Estimated Cost to Fix: $800 - $1500+
  • Recalls: None Found
• Faulty ignition coils

Summary

The 2015 Chevrolet Traverse, while generally a reliable and comfortable family SUV, does suffer from several notable issues. The most significant and potentially expensive problems revolve around the engine’s timing chain and the transmission’s wave plate failure, with repair costs easily exceeding several thousand dollars. Other issues like suspension components and electrical problems, while less costly, can still be inconvenient and add to the overall cost of ownership. Potential buyers should be aware of these common issues and thoroughly inspect any used 2015 Traverse before purchasing, paying particular attention to any unusual noises from the engine or transmission.
