What year to avoid GX470?

For most buyers, the earliest GX470s—especially the 2003 and 2004 models—are the ones to avoid if you want a better reliability profile. Later years generally offer improvements, though condition and maintenance history always matter. The GX470 was produced from 2003 to 2009, with the GX460 succeeding it in 2010, so used examples today vary widely by miles and service records.

Model-year reliability snapshot

The GX470’s reliability varies by year. Here is a quick, year-by-year snapshot of commonly reported issues and strengths to help you navigate a used-purchase decision.

2003-2004: early teething years

• 2003 — First-year production typically shows more electrical gremlins and warranty claims; some owners report transmission quirks and transient electrical faults.


• 2004 — Similar early-year concerns persist, with occasional steering/suspension wear and higher maintenance costs cited by owners with higher mileages.

Bottom line: If you’re shopping these years, expect to encounter more maintenance nuances and potentially higher upkeep costs compared with later GX470s.

2005-2009: later-year improvements

• 2005 — Reliability generally improves as fixes from the early run are phased in; verify comprehensive service history.


• 2006 — Solid overall reliability in many reports; pay attention to wear items as mileage climbs, but major failures are less common than in 2003–2004.


• 2007 — Widely considered among the more dependable years in the GX470 lineup when well maintained.


• 2008-2009 — Final years before the GX460 launch; often the most refined of the GX470s, with many issues resolved from earlier production.

Bottom line: 2005–2009 generally offer the better reliability profile, especially when the vehicle has a strong maintenance history and no signs of neglect.

Practical buying tips for a GX470

To maximize your chances of a trouble-free purchase, focus on inspection criteria and provenance that reflect a history of proper care rather than just the model year.

• Complete maintenance records, including timing/drive components, transmission service, and any recall work.


• Underside rust and frame integrity, especially for vehicles from regions with heavy road salt exposure.


• Assessment of 4WD components, suspension bushings, and steering linkage for wear that typically accompanies higher mileage.


• Electrical system checks: windows, door locks, sunroof, and dashboard warning lights; run a diagnostic scan for stored codes.


• Interior wear and safety systems: seat electronics, airbags, and overall cosmetic condition; verify any safety recalls have been completed.

Tip: A pre-purchase inspection by a trusted mechanic, plus a recall history check by VIN, can significantly reduce the risk of hidden issues after you buy.

Recalls and safety checks

Recall awareness matters. Always verify that any open campaigns have been addressed and review the vehicle’s recall history against official databases.

• Check the VIN against NHTSA and Toyota recall portals for open or completed campaigns.


• Confirm safety-related recalls (airbags, braking, steering, etc.) have been addressed by a dealership or authorized service center.


• Consider a professional recall history check if you’re uncertain about the VIN’s campaign status.

Note: While recall campaigns vary, ensuring they are up to date is a simple, important step when buying any used GX470.

Summary

In the GX470 lineup, the earliest 2003–2004 models tend to pose more reliability questions, whereas 2005–2009 models generally offer better odds, provided they come with thorough maintenance histories. Always prioritize a comprehensive service record, a clean recall history, and a careful pre-purchase inspection to minimize risk. With diligence, a later-year GX470 can be a durable, capable SUV that ages well.

What is the most reliable year for the Lexus GX?

The most reliable Lexus GX years are generally considered to be 2021 and 2022, with the 2021 model being called the "pinnacle" of the previous generation due to being late enough in the production cycle to have most issues resolved. The entire 2010-2023 GX 460 generation is known for its long-term reliability, thanks to its tried-and-true V8 engine and solid construction.

Most reliable years to consider

• 2021: Often cited as the best year of the last generation, as it's considered late enough in the model cycle for most bugs to have been worked out. 
• 2022: Also received top marks for reliability, according to sources like Top Speed. 
• 2010-2023 GX 460 generation: This entire generation is highly reliable, with the V8 engine and 6-speed automatic transmission being known for their longevity. The 2010 model year was an early target for a software update regarding the Vehicle Stability Control (VSC), but other years are very dependable. 

Potential issues to watch for

• Oil leaks: Some oil leaks can occur, especially on 2016 and 2017 models. 
• Rust: Models driven in regions with heavy road salt may be prone to rust, particularly on older versions. 
• Timing belt: The 4.7L V8 in the earlier GX 470 models requires a timing belt replacement every 100,000 miles, which is a potential maintenance cost to consider. 

Overall reliability

• The Lexus GX is consistently ranked as one of the most reliable luxury SUVs due to its sturdy body-on-frame construction and Toyota engineering. 
• With proper maintenance, a GX can last for over 300,000 miles. 
• The long-running GX 460 (2010-2023) is a good choice for long-term ownership due to its simplified and robust technology compared to newer, more complex vehicles. 

What is the best year of the Lexus LX 470?

The best year for the LX 470 is subjective and depends on your priorities, but late models from 2006-2007 are often recommended for their improved VVTi engine and 5-speed transmission, while earlier models like 2000-2002 are praised for having fewer complex electronic systems. For many, the 2004 model represents a great balance of features and reliability, earning J.D. Power's initial quality award.

How many miles can a Lexus GX470 last?

A Lexus GX 470 can last well over 200,000 miles, with many owners reporting longevity of 250,000 to 300,000 miles or more, thanks to its durable 4.7L V8 engine and robust drivetrain. Longevity depends heavily on consistent maintenance, including regular oil changes, and addressing potential issues like the timing belt and water pump replacement. 
Factors contributing to longevity

• Reliable powertrain: The 4.7L 2UZ-FE V8 engine is known for its durability and can last hundreds of thousands of miles with proper care. 
• Robust chassis: The full-time four-wheel-drive system and transfer case are built to be durable. 
• Proactive maintenance: Following the manufacturer's maintenance schedule is crucial, especially for critical components. This includes replacing the timing belt, water pump, and performing regular fluid checks and changes for the transmission and differentials. 
• Addressing common issues: While reliable, some parts have known failure points that can be addressed as they arise. The air suspension is a common item that may need replacement around 200,000 miles, and checking for rust is important, especially in certain climates. 

What to consider when buying a high-mileage model

• Maintenance history: A vehicle with a well-documented history of maintenance is a much safer bet than one with a spotty record, regardless of mileage. 
• Condition over mileage: A well-maintained GX with 250,000 miles might be in better condition than a poorly maintained one with only 150,000 miles. 
• Common wear and tear: Be prepared for the possibility of replacing air suspension components, CV joints, or frame bushings, which are common on older, high-mileage SUVs.

• Air suspension: The original air suspension system can be an issue, and sensors for the rear air leveling may fail over time. Many owners replace the air suspension with traditional springs. 
• Radio: Problems with the original radio may necessitate replacement. 
• Other potential issues:
  • Check Engine Light: Be aware of potential codes related to the evaporative emissions system (P0440, P0441, P0442, or P0446). 
  • Airbag/Seat codes: Warning lights can be triggered by a seat position fault code (B1153) or airbag codes (B0111 and/or B0116). 
  • Leather: The original leather interior material can deteriorate over time. 
  • Outdated technology: The original navigation system is outdated, and replacing it can be complex.
