Reliability: What to Expect

So, how reliable is the 1997 Infiniti Q45? Well, like any car of this age, it has its quirks. But overall, it's known to be fairly dependable if properly maintained. Let’s break it down:

  • Engine Reliability: The V8 engine is generally robust. Regular oil changes and maintenance are crucial to keep it running smoothly. Issues can arise with age, such as worn gaskets and seals, leading to oil leaks. However, with proper care, the engine can provide many years of reliable service.

These problems are common in older cars and can often be attributed to wear and tear. Addressing these issues promptly can prevent them from escalating into more significant problems.

  • Maintenance: Regular maintenance is key. This includes oil changes, tune-ups, and keeping an eye on fluid levels. Staying on top of maintenance can help prevent major breakdowns and keep the car running smoothly. Neglecting maintenance can lead to costly repairs down the road.

  • Rust: Check for rust, especially in areas prone to it like the wheel wells and undercarriage. Rust can compromise the structural integrity of the car and lead to expensive repairs. Addressing rust promptly can prevent it from spreading and causing further damage.

  • Suspension: The suspension can wear out over time, leading to a less comfortable ride. Replacing worn suspension components can restore the car's ride quality and handling. Regular inspections of the suspension system can help identify potential problems early on.
