The Toyota Highlander debuted in the U.S. market in 2001, offering a unique combination of car-like handling and SUV versatility. Positioned in the midsize SUV segment, it quickly became a family favorite for its reliability, spacious interior, and smooth ride. Over the years, the Highlander evolved significantly. The early models were compact and practical, while newer generations became larger, incorporating a third row, advanced technology, enhanced safety features, and more refined interiors. Drivers particularly love the Highlander for its all-weather capability, thanks to optional all-wheel drive, and its reputation for longevity. However, even the best vehicles have their rough patches. Some Highlander years fell short of Toyota’s high standards, often due to manufacturing flaws or design missteps. Let’s dive into five Toyota Highlander years to avoid and the challenges they brought to owners.

2003 Toyota Highlander

The 2003 Highlander is part of the first generation and a prime example of early-model mechanical issues. The most notorious problem in this year involves the engine’s stripped bolts, leading to coolant leaks and overheating. The bolt design on the four-cylinder engine was particularly problematic, causing the threads to loosen and making it impossible for the bolts to maintain a proper seal.

This issue typically emerged around 125,000 to 130,000 miles, often requiring engine rebuilds or even replacements. These repairs were not only costly but also a major inconvenience for owners. Beyond engine problems, the suspension system of this model often wore out prematurely, contributing to a less stable and noisier ride over time.

Why avoid: Significant engine flaws and high repair costs make the 2003 Highlander a risky choice for buyers seeking long-term reliability.

2008 Toyota Highlander

Toyota launched the second generation of the Highlander in 2008, bringing a new design, updated powertrains, and a larger interior. Unfortunately, first-year redesigns often come with growing pains, and the 2008 Highlander was no exception. Owners frequently reported issues with the engine, such as rattling noises, oil leaks, and sensor failures that could lead to engine stalling. Additionally, the electrical system was prone to glitches, with malfunctions in features like power windows, door locks, and dashboard indicators.

The 2008 Highlander also faced complaints about its braking system. Some owners reported soft brake pedals, which Toyota later addressed through recalls and technical service bulletins. Despite its promising new features, these reliability concerns made this model less appealing compared to its successors.

Why avoid: Engine, electrical, and brake problems overshadow the benefits of this first-year redesign.

2014 Toyota Highlander

The 2014 Highlander kicked off the third generation with a stylish redesign and expanded features. However, it also brought along recurring mechanical problems. Stripped engine bolts resurfaced as a major issue, causing coolant leaks and overheating. The suspension system, including the front struts and control arms, often required premature replacement, impacting ride quality and handling.

Infotainment issues were another sore spot for 2014 Highlander owners. The system frequently froze or lagged, detracting from the vehicle’s overall appeal in a tech-savvy era. While Toyota resolved many of these issues in later years, the 2014 model remains a weak link in the Highlander’s generally strong lineup. As such, it’s on our list of Toyota Highlander years to avoid.

Why avoid: A mix of mechanical and technological problems makes this model year less reliable and enjoyable.

2015 Toyota Highlander

Building on the challenges of 2014, the 2015 Highlander inherited many of the same issues. Engine problems continued, with oil leaks and stripped bolts being common complaints. This model year also faced transmission concerns, including rough shifting, delayed gear changes, and even complete transmission failures in some cases.

Another frequent issue was premature wear on the braking system, with some owners needing to replace brake pads and rotors much earlier than expected. Despite its spacious interior and family-friendly design, these mechanical shortcomings significantly impacted owner satisfaction.

Why avoid: Persistent engine and transmission issues, coupled with brake wear, make the 2015 Highlander a less dependable option.

2020 Toyota Highlander

The fourth-generation Highlander arrived in 2020, bringing significant improvements in technology and fuel efficiency. However, early adopters of this redesigned model faced some challenges. The new infotainment system was criticized for being unresponsive, with frequent lags and software glitches. Additionally, the hybrid powertrain, though innovative, experienced occasional performance inconsistencies.

Interior design also drew criticism. The third-row seating was tighter than in many competitors, and cargo space felt limited for a vehicle of its size. These factors, combined with minor manufacturing quirks, made the 2020 Highlander less desirable than its more refined successors in the same generation.

Why avoid: Early redesign issues and subpar interior functionality make this year less appealing compared to later models.

How to Spot a Reliable Highlander

If you’re considering a used Toyota Highlander, here are some tips to ensure you pick a dependable model:

• Research Specific Models: Use online resources like MotorBiscuit’s seamless car buying tool to compare listings, understand your local market, and find the best deal in your area.
• Check the VIN: Look up the Vehicle Identification Number (VIN) to review the vehicle’s history, including recalls and maintenance records.
• Test Drive Thoroughly: Pay attention to how the engine, transmission, and brakes perform. Listen for unusual noises and test all electronics.
• Get a Pre-Purchase Inspection: Hire a trusted mechanic to inspect the vehicle for hidden problems before finalizing your purchase.

The Toyota Highlander is a beloved midsize SUV with a strong reputation for reliability and family-friendly features. However, like any long-running vehicle model, it has had its fair share of problematic years. Avoiding 2003, 2008, 2014, 2015, and 2020 Highlanders can save you from potential headaches and costly repairs. By conducting thorough research and inspections, you can find a Highlander that delivers the comfort, reliability, and performance Toyota is known for.
