Back to Generation

The 2018 Toyota Camry, part of the eighth generation (XV70), has been generally praised for its reliability and performance. However, some owners have reported performance issues. Below are the most common performance-related issues, symptoms, diagnostic steps, and potential solutions.

Common Performance Issues

  1. Engine Hesitation

    • Symptoms: The engine may hesitate or stumble during acceleration, particularly when merging onto highways or during rapid acceleration from a stop.

  2. Transmission Shifting Problems

    • Symptoms: Rough shifting, delayed engagement, or slipping while changing gears.

  3. Poor Fuel Economy

    • Symptoms: Noticeable drop in miles per gallon (MPG) compared to EPA ratings.

  4. Vibrations or Noise While Driving

    • Symptoms: Unusual vibrations felt in the steering wheel or throughout the car, often accompanied by noise when driving at higher speeds.

Tools Required:

  • OBD-II scanner
  • Multimeter
  • Basic hand tools (screwdrivers, wrenches)
  • Fuel pressure gauge

Steps:

  1. Check for Diagnostic Codes:

    • Use the OBD-II scanner to check for any stored trouble codes that may indicate issues with the engine or sensors.

  2. Inspect Air Intake System:

    • Check the air filter for clogs and inspect the intake hoses for leaks.

  3. Test Fuel System:

    • Use a fuel pressure gauge to measure fuel pressure at the rail. Compare the readings to factory specifications.

  4. Inspect Throttle Body:

    • Remove the throttle body and check for carbon buildup. Clean it if necessary.

  5. Check Spark Plugs and Ignition System:

    • Remove and inspect the spark plugs for wear. Replace if necessary. Test ignition coils for proper resistance.

  6. Road Test:

    • Conduct a road test under various conditions to replicate the hesitation issue.

Tools Required:

  • OBD-II scanner
  • Transmission fluid dipstick or funnel
  • Torque wrench
  • Basic hand tools

Steps:

  1. Check Transmission Fluid Level:

    • With the engine running, check the transmission fluid level using the dipstick. Add fluid if low and inspect for discoloration or a burnt smell.

  2. Scan for Codes:

    • Use the OBD-II scanner to check for transmission-related trouble codes.

  3. Inspect Transmission Linkage:

    • Ensure that the transmission linkage is properly adjusted and that there are no obstructions.

  4. Test Transmission Control Module (TCM):

    • If equipped, check the TCM for proper operation using a multimeter.

  5. Road Test:

    • Conduct a road test to see if the transmission issues persist after checking fluid and electronics.

Tools Required:

  • OBD-II scanner
  • Fuel pressure gauge
  • Tire pressure gauge

Steps:

  1. Check Tire Pressure:

    • Ensure all tires are inflated to the recommended pressure.

  2. Scan for Codes:

    • Use the OBD-II scanner to check for any engine codes that may indicate a malfunction affecting fuel economy.

  3. Inspect Air Filter:

    • Check and replace the air filter if it’s clogged.

  4. Check Fuel System:

    • Measure fuel pressure and inspect for leaks or injector issues.

  5. Monitor Driving Habits:

    • Evaluate driving patterns. Aggressive driving can significantly reduce fuel economy.

Tools Required:

  • Floor jack and jack stands
  • Wheel chocks
  • Torque wrench
  • Basic hand tools

Steps:

  1. Visual Inspection:

    • Check for any visible damage to tires, wheels, and suspension components.

  2. Wheel Balance and Alignment:

    • Ensure that wheels are balanced and that the vehicle is properly aligned.

  3. Inspect Suspension Components:

    • Check for worn or damaged bushings, ball joints, and struts.

  4. Road Test:

    • Conduct a road test to replicate the vibration or noise and identify the speed at which it occurs.

  5. Check Driveshaft and Axles:

    • Inspect the driveshaft and axles for any signs of wear or damage if the vehicle is all-wheel drive.
Conclusion

While the 2018 Toyota Camry is known for its reliability, certain performance issues can occur. Regular maintenance and prompt attention to symptoms can help mitigate these issues. Always refer to the vehicle's service manual for specific repair procedures and specifications. If issues persist after diagnostics and repairs, it may be beneficial to consult with a certified Toyota technician.
