The 2025 Toyota Highlander aims to continue its legacy as a reliable and family-friendly SUV. However, even with Toyota's reputation for quality, no vehicle is immune to potential issues. Understanding the common problems that might arise with the 2025 Highlander can help you make an informed purchase decision, prepare for potential maintenance, and keep your vehicle running smoothly for years to come. Let's dive into what owners and experts are anticipating.

Let's Talk Powertrain: What Could Go Wrong?

The Highlander offers a few powertrain options, and each comes with its own set of potential concerns. While Toyota has refined these engines over the years, certain issues can still pop up.

  • The Turbocharged 2.4L Engine: A Promising Replacement, But… The Highlander ditched the V6 in favor of a turbocharged 2.4-liter four-cylinder engine. While this engine offers competitive fuel economy and decent power, turbochargers themselves can be a source of potential problems down the line.
    • Turbo Lag: Some drivers have reported experiencing noticeable turbo lag, particularly at lower RPMs. This can result in a slight delay in acceleration, which can be frustrating in certain driving situations, like merging onto the highway.
    • Turbocharger Failure: Although rare, turbochargers are complex pieces of equipment that operate under high stress. Potential failure points include oil leaks, bearing wear, and wastegate malfunctions. Regular oil changes with the correct synthetic oil are crucial to maintaining turbocharger health.
    • Carbon Buildup: Direct-injection engines, like the 2.4L turbo, are susceptible to carbon buildup on the intake valves. This can reduce engine performance and fuel economy over time. Consider using a fuel system cleaner periodically to help prevent carbon buildup.
  • Hybrid System Hiccups: Keeping the Electric Side Healthy The Highlander Hybrid offers excellent fuel efficiency, but it relies on a complex hybrid system that includes a gasoline engine, electric motors, and a battery pack.
    • Battery Degradation: Like all batteries, hybrid batteries degrade over time. The rate of degradation depends on factors like driving habits, climate, and maintenance. While Toyota offers a warranty on the hybrid battery, it's important to be aware of this potential long-term cost.
    • Inverter Issues: The inverter is a critical component that converts DC power from the battery to AC power for the electric motors. Inverter failures can be costly to repair.
    • Regenerative Braking Problems: Occasionally, drivers report issues with the regenerative braking system, which can feel inconsistent or jerky. This is usually a software issue that can be resolved with a software update.
  • Transmission Troubles: Smooth Shifting is Key Both the gasoline and hybrid Highlanders use automatic transmissions. While generally reliable, some potential issues can arise.
    • Rough Shifting: Some owners have reported experiencing rough or delayed shifting, particularly in the lower gears. This could be a sign of low transmission fluid or a more serious transmission problem.
    • Transmission Slippage: In rare cases, transmission slippage can occur, where the engine revs up without a corresponding increase in speed. This is a serious issue that requires immediate attention.
    • Torque Converter Issues: The torque converter is responsible for transferring power from the engine to the transmission. Torque converter problems can manifest as shuddering or vibrations at low speeds.

Tech Troubles: When Gadgets Go Wrong

The 2025 Highlander is packed with technology, from its infotainment system to its advanced driver-assistance features. However, technology can be finicky, and some issues are common across many modern vehicles.

  • Infotainment System Glitches: When the Screen Goes Blank The infotainment system is the central hub for controlling many of the vehicle's functions.
    • Software Freezes: The infotainment system can sometimes freeze or become unresponsive. This can usually be resolved by restarting the system or performing a software update.
    • Connectivity Issues: Problems with Bluetooth connectivity, Apple CarPlay, or Android Auto are common. Make sure your phone's software is up to date and try resetting the connection.
    • Navigation Errors: The navigation system may provide inaccurate directions or fail to update properly. Ensure your map data is current.
  • Advanced Driver-Assistance System (ADAS) Issues: Staying Safe on the Road The Highlander comes standard with Toyota Safety Sense, a suite of ADAS features designed to enhance safety.
    • False Alerts: The system may occasionally issue false alerts, such as warnings about potential collisions that are not actually present. This can be annoying and distracting.
    • Sensor Malfunctions: The ADAS features rely on sensors that can be affected by weather conditions, dirt, or damage. If a sensor malfunctions, the corresponding feature may not work correctly.
    • Adaptive Cruise Control Problems: Issues with adaptive cruise control can include inconsistent speed maintenance or failure to properly detect vehicles ahead.
  • Electrical Gremlins: Mysterious Malfunctions Electrical issues can be difficult to diagnose and resolve.
    • Battery Drain: Excessive battery drain can occur due to faulty electrical components or leaving accessories on.
    • Sensor Failures: Sensors throughout the vehicle can fail, causing various problems. Examples include faulty tire pressure sensors or malfunctioning parking sensors.
    • Lighting Issues: Problems with headlights, taillights, or interior lights are common.

Interior Annoyances: Comfort and Convenience Concerns

While the Highlander's interior is generally well-designed, some common complaints can arise.

  • Seat Comfort: Some drivers find the seats to be uncomfortable on long trips, particularly the second and third-row seats. Consider test driving the vehicle extensively to assess seat comfort.
  • Third-Row Access: Access to the third row can be challenging, especially for adults.
  • Interior Trim Quality: While Toyota's are usually durable, some owners have noted that the interior trim materials in the Highlander could be more luxurious.
  • Noisy Cabin: Road noise and wind noise can be noticeable at highway speeds.

Body and Exterior Blemishes: Keeping it Looking Good

Exterior problems can range from minor cosmetic issues to more serious structural concerns.

  • Paint Quality: Some owners have reported that the paint is susceptible to chipping and scratches. Consider applying a paint protection film to vulnerable areas.
  • Rust: While Toyota has improved its rustproofing measures, rust can still be a problem in areas with harsh winters and road salt. Regularly wash and wax your vehicle to protect the paint.
  • Door and Window Issues: Problems with door seals, window regulators, or power locks can occur.
  • Alignment Problems: Premature tire wear could be the result of poor factory alignment.

Recalls and Technical Service Bulletins: Staying Informed

It's crucial to stay informed about any recalls or technical service bulletins (TSBs) that may be issued for the 2025 Highlander.

  • Recalls: A recall is issued when a safety-related defect is discovered. Toyota will notify owners of affected vehicles and provide a free repair.
  • Technical Service Bulletins (TSBs): TSBs are issued to address common problems that are not safety-related. TSBs provide guidance to technicians on how to diagnose and repair these problems.
  • Staying Updated: Check the National Highway Traffic Safety Administration (NHTSA) website or the Toyota website regularly for any recalls or TSBs that may apply to your vehicle.

Preventative Maintenance: The Key to Longevity

Regular maintenance is essential for preventing many of the problems discussed above.

  • Regular Oil Changes: Follow the recommended oil change schedule to keep the engine properly lubricated and prevent wear.
  • Fluid Checks: Regularly check and top off all fluids, including coolant, brake fluid, power steering fluid, and transmission fluid.
  • Tire Maintenance: Maintain proper tire pressure and rotate your tires regularly to ensure even wear.
  • Brake Inspections: Have your brakes inspected regularly to ensure they are in good working order.
  • Scheduled Maintenance: Follow the recommended maintenance schedule in your owner's manual.
