1. Transmission Problems

Some owners have reported issues with the Continuously Variable Transmission (CVT) in the 2021 Honda Accord. These issues range from jerky shifts to transmission slipping.

• Solution: For jerky shifts, a software update from Honda can often resolve the issue. If the transmission is slipping, a more thorough inspection may be required, which could involve replacing the transmission fluid or, in more severe cases, replacing the transmission itself.

2. Electrical System Issues

There have been complaints about various electrical components malfunctioning, such as the infotainment system, adaptive cruise control, and other electronic features.

• Solution: Perform a soft reset of the infotainment system by holding the power button for several seconds. For more persistent issues, a firmware update from the dealership can help. If electronic components continue to fail, a comprehensive diagnostic check of the electrical system may be necessary.

3. Brake Problems

Some owners have noted issues with the brakes, including grinding noises and reduced braking performance.

• Solution: Grinding noises usually indicate worn-out brake pads, which should be replaced immediately. If the problem persists, have a professional inspect the brake rotors and calipers. Reduced braking performance could also be due to air in the brake lines or a need for new brake fluid.

4. Engine Performance Issues

Certain users have reported problems with engine performance, such as decreased acceleration or unexpected stalling.

• Solution: Ensure that the vehicle's engine is receiving the proper type of fuel and that the fuel filter is not clogged. Regular maintenance, such as oil changes and air filter replacements, can help maintain engine performance. If the problem persists, a diagnostic check can reveal more specific issues like faulty spark plugs or sensors.

5. Suspension Concerns

Some drivers have experienced issues with the suspension, such as noise when driving over bumps or a rough ride.

• Solution: Inspect the suspension components like struts, shocks, and bushings for wear and tear. Replacing worn-out parts can improve the ride quality. In some cases, a professional alignment can resolve issues relating to a rough ride.

6. Fuel System Problems

Complaints about poor fuel economy or fuel system issues have also been noted by some owners.

• Solution: Regular maintenance such as replacing the fuel filter and using high-quality fuel can help improve fuel economy. Additionally, having the fuel injectors cleaned can enhance performance. For more severe issues, a comprehensive diagnostic check of the fuel system may be required.

7. Interior Quality Issues

Some users have reported concerns about the interior quality, including rattling noises and issues with upholstery.

• Solution: For rattling noises, check for loose interior panels or components and secure them. Upholstery issues may require professional cleaning or repair, and in severe cases, replacement.
