The Chevrolet Trailblazer, a robust seven-seat SUV, has been a popular choice for families and those needing serious towing capability in New Zealand. Built on a ladder-frame chassis, it's a capable vehicle both on and off-road. Let's delve into the specifics of these Trailblazers, their strengths and weaknesses, and how to keep them performing well in our unique NZ environment.
Common problems with the Trailblazer include: Injector issues (diesel engines), DPF (Diesel Particulate Filter) issues (diesel engines used for short trips), Suspension wear (knocks and reduced handling), Turbocharger failures (diesel engines - listen for whistling noises), and Electrical glitches (sensor failures).
WOF failures on the Trailblazer often involve: Tyre condition (pay attention to tread depth and sidewall damage), Brake performance (check for worn pads, discs, and fluid leaks), Suspension components (worn ball joints, bushes, and leaking shock absorbers), Lighting (check all lights, including trailer wiring), and Rust in structural areas. Check for evidence of heavy towing that has caused damage to the towbar or chassis.
The Trailblazer is built for ruggedness and versatility. Primarily powered by a Duramax diesel engine, known for its torque and reliability. Regular oil changes are vital to keep the engine in top form, particularly in the harsh working conditions that some Trailblazers endure. The automatic transmission should be serviced regularly to maintain smooth shifting. Due to their high riding height and potential off-road use, suspension components are subject to wear. Inspect ball joints, bushes, and shock absorbers carefully during servicing and WOF inspections. Check for any signs of rust, especially on models used near the coast or on unsealed roads. Interior trim is durable, but check for wear and tear, particularly in vehicles used for family duties. A pre-purchase inspection is highly recommended to reveal any hidden mechanical or bodywork issues.
