The Infiniti Q45 was a popular luxury sedan among some chauffeur companies in the past, including those operating Scottsdale Airport Limo services, for several key reasons. However, it’s important to note that the Q45 was discontinued in 2006, and most modern limo services have moved on to newer luxury models. That said, here’s why the Infiniti Q45 was once favored:

🔑 Key Reasons It Was Popular:

1. Luxurious Ride Quality
   The Q45 was designed to compete with the Mercedes S-Class and Lexus LS. It offered a quiet, smooth, and refined ride—ideal for transporting clients who expect comfort to and from Phoenix Sky Harbor or Scottsdale Airport.
2. Powerful V8 Engine
   With a 5L V8 engine, the Q45 delivered strong acceleration and high-speed cruising comfort, making it a solid performer on Arizona highways and for airport pickups with tight schedules.
3. High-End Interior Features
   Leather seating, wood trim, powerful climate control (important in Arizona heat), and advanced (for the time) infotainment made the Q45 a comfortable and tech-forward choice for business travelers and VIPs.
4. Rear Passenger Space
   Scottsdale Chauffeur Servicecompanies in Arizona appreciated the spacious rear cabin and rear climate controls in later models. Clients could relax or work in the back seat in a more executive-style layout.
5. Underrated Prestige
   While not as flashy as a BMW or Mercedes, the Q45 offered a low-key luxury vibe, which appealed to clients wanting comfort and class without the attention.
6. Value for Money
   When bought pre-owned, Q45s were often less expensive to acquirethan German counterparts, making them attractive to smaller limo companies or private chauffeurs building fleets on a budget.

⚠️ Why It’s Rare Now in Scottsdale Limo Fleets:

• Discontinued in 2006– No longer in production, so parts are harder to find.
• Older technology– No Apple CarPlay, limited safety features compared to modern cars.
• Fuel economy– V8 engines aren’t ideal for companies looking to cut fuel costs.
• Luxury standards have evolved– Modern clients often expect features like Wi-Fi, USB ports, and massage seats.

Modern Alternatives in Scottsdale Limo Fleets:

Chauffeur companies in Scottsdale today are more likely to use:

• Cadillac CT4/CT5 or Escalade
• Lincoln Navigator or Aviator
• Mercedes-Benz E-Class or S-Class
• Lexus LS or Genesis G90
• Tesla Model X or Model S(for eco-conscious clients)

If you’re considering building or upgrading a limo fleet in Scottsdale, Arizona, you’re better off choosing newer models that combine comfort, luxury, and fuel efficiency while handling the intense heat and long-distance demands of airport transfers.

If a chauffeur company in Scottsdale, Arizona is using an Infiniti Q45 as a daily airport limo, they should prepare for moderate to high maintenance costs, especially given the vehicle’s age (since the Q45 was discontinued after 2006). Here’s what to realistically expect:

🔧 Maintenance Expectations (Daily Use in Arizona Conditions)

1. Engine & Drivetrain (High Attention Needed)

• The Q45’s 5L V8is reliable but complex. Daily usage will stress:
  • Timing chain components
  • Valve cover gaskets(common oil leak point)
  • Cooling system(essential in Arizona heat)
• Expect $1,000–$2,500/yearon engine-related upkeep if driving daily.

2. Transmission

• The automatic transmission is solid but can wear out with constant airport trips.
• Transmission flushesare needed every 30K–50K miles.
• Rebuilds (if needed) can run $2,000–$3,500.

3. Suspension & Steering

• Active suspensionon some Q45 trims (like the Q45a) is expensive to repair.
• Control arms, bushings, shocks/struts may need replacement every 60K–80K mileswith hard use.
• Budget $1,000–$2,000/yearif carrying clients daily.

4. Electrical Systems

• Aging Q45s tend to develop electrical gremlins:
  • Power seat motors
  • Climate controls (especially rear vents)
  • Display and gauge cluster backlighting
• Scottsdale heat accelerates degradation of plastic connectors and wiring.

5. Air Conditioning (Critical in Arizona)

• AC systems on older Q45s often require compressor or refrigerant servicedue to heat exposure.
• Budget for annual servicing($300–$800).

6. Interior Wear

• Leather, dashboard plastics, and headliner suffer in Arizona’s sun if not garage-kept.
• Frequent cleaning and conditioning, or even reupholstering, may be needed for a premium limo experience.

💸 Estimated Annual Maintenance Costs (Daily Use)

⚠️ Additional Scottsdale-Specific Considerations

• Desert climatewears out rubber, fluids, and cooling systems faster.
• Dust and debrisfrom desert roads can clog air filters and require frequent cleaning.
• Must garage or shade the car to prevent UV damage to the paint and interior.

🧠 Final Recommendation

While the Q45 can work as a nostalgic or budget luxury option, using it daily for Scottsdale airport runs is not sustainable long-term without frequent, costly upkeep. If you’re committed to using one:

• Keep a mechanic familiar with older Infiniti V8son call.
• Stockpile OEM or quality aftermarket parts
• Use it for occasional VIP runs, not daily shuttling.
