Maintenance Issues to Look Out for in a 2023 Toyota Highlander (Fourth Generation)

The 2023 Toyota Highlander, part of the fourth generation (2020-present), is a reliable SUV but still requires regular maintenance to ensure optimal performance and longevity. Below are common maintenance issues, symptoms, diagnostic steps, required tools, and repair instructions to help you keep your Highlander in excellent condition.

1. Oil Change and Engine Maintenance
Tools Required
  • Oil filter wrench
  • Socket set
  • Oil catch pan
  • New engine oil (refer to the owner’s manual for specifications)
  • New oil filter
  • Funnel
  • Rags for cleanup
Repair Instructions
  1. Prepare the Vehicle: Park the Highlander on a level surface and turn off the engine. Allow it to cool down.
  2. Drain Old Oil: Place the oil catch pan under the oil pan. Remove the drain plug with a socket wrench and allow the old oil to drain completely.
  3. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Lubricate the rubber seal of the new filter with a little new oil and install it by hand.
  4. Install Drain Plug: Reinstall the drain plug and tighten it securely.
  5. Add New Oil: Open the hood, remove the oil filler cap, and use a funnel to pour in the new oil. Check the level with the dipstick and add more if necessary.
  6. Check for Leaks: Start the engine and let it run for a few minutes. Check under the vehicle for any leaks.
2. Brake System Inspection
Tools Required
  • Jack and jack stands
  • Lug wrench
  • Brake cleaner
  • Caliper tool
  • Torque wrench
  • New brake pads and rotors (if necessary)
Repair Instructions
  1. Lift the Vehicle: Use a jack to lift the Highlander and secure it with jack stands. Remove the wheels using a lug wrench.
  2. Inspect Brakes: Examine the brake pads for thickness. If they are less than 1/4 inch, they need replacement. Check rotors for grooves or warping.
  3. Replace Brake Pads: Remove the caliper bolts with a socket wrench and slide out the caliper. Remove the old pads and install new ones. Use a caliper tool to compress the caliper piston if needed.
  4. Reinstall Caliper: Place the caliper back onto the rotor and secure it with the caliper bolts.
  5. Reassemble Wheels: Put the wheel back on, torque the lug nuts to the manufacturer specifications, and lower the vehicle.
3. Tire Maintenance
Tools Required
  • Tire pressure gauge
  • Tread depth gauge
  • Jack and jack stands (for rotation)
  • Torque wrench (for lug nuts)
Repair Instructions
  1. Check Tire Pressure: Remove the valve cap and press the tire pressure gauge onto the valve stem. Adjust pressure to the recommended PSI listed on the driver’s door jamb.
  2. Inspect Tread Depth: Use a tread depth gauge in several spots across each tire to check for uneven wear.
  3. Rotate Tires: If necessary, lift the vehicle, remove the wheels, and rotate them according to the recommended pattern (front to back, side to side).
  4. Reinstall Wheels: Ensure they are tightened to the manufacturer’s specifications with a torque wrench.
4. Battery Maintenance
Tools Required
  • Multimeter
  • Wrench set
  • Battery terminal cleaner
  • Battery replacement (if necessary)
Repair Instructions
  1. Check Voltage: With a multimeter set to DC voltage, connect the red lead to the positive terminal and the black lead to the negative terminal. A healthy battery should read around 12.6 volts.
  2. Inspect Terminals: If corrosion is present, disconnect the battery terminals (negative first), clean them with a terminal cleaner, and reconnect them securely.
  3. Replace Battery: If the battery is faulty, remove it and install a new one, ensuring the positive and negative terminals are correctly connected.
Conclusion

Regular maintenance of your 2023 Toyota Highlander is essential for ensuring its reliability and performance. By following these maintenance steps, you can address common issues that may arise and keep your SUV in optimal condition. Always refer to the owner’s manual for specific recommendations and specifications. If you’re unsure or uncomfortable performing any maintenance, it's advisable to consult with a professional mechanic.
