2020 Toyota Highlander: Common Problems and Solutions

The 2020 Toyota Highlander, a popular midsize SUV, has earned praise for its reliability and family-friendly features. However, like any vehicle, it is not without its issues. Understanding these common problems can help owners stay ahead of maintenance and potential repairs.

This article explores typical challenges faced by 2020 Highlander owners and offers practical solutions.

Engine Performance Issues

The 2020 Toyota Highlander is generally reliable, but some owners have reported engine performance concerns that affect its driving experience. A common issue is a discrepancy between advertised and real-world fuel efficiency. This can be influenced by factors such as driving habits, terrain, and fuel quality. Using high-quality fuel and adhering to regular maintenance can help optimize performance.

Another reported problem is rough idling or stalling, particularly during cold starts. This may be related to the air intake system or fuel injectors. Cleaning these components and ensuring the engine’s software is updated can often resolve the issue.

Unusual engine noises, such as those stemming from the timing chain or belt, have also been noted. Regular inspections and timely replacement of these components can prevent more significant problems.

Transmission Concerns

Some owners have experienced transmission issues with the 2020 Toyota Highlander. A frequently mentioned problem is hesitation or delay when shifting gears, particularly during acceleration. This is often attributed to software glitches in the transmission control module. Checking for software updates from Toyota can improve responsiveness.

Abrupt or jerky shifts, especially at lower speeds, have also been reported. These irregularities may result from the adaptive transmission logic, which adjusts to driving habits over time. Resetting this system, which can be done by a technician, may restore smoother shifting.

Regular fluid checks and timely replacement with the recommended transmission fluid are essential for maintaining the transmission system’s reliability and preventing wear.

Infotainment Glitches

The infotainment system in the 2020 Toyota Highlander has been a source of frustration for some owners. Issues with the touchscreen interface, such as unresponsiveness or lag, have been reported. A system reboot can temporarily address this, but persistent problems may require a software update.

Bluetooth connectivity has also been inconsistent for some users, with difficulties in pairing devices or maintaining stable connections. Ensuring both the vehicle’s system and mobile devices are updated can improve compatibility. Clearing the system’s Bluetooth cache may also help.

Integration of smartphone apps via Apple CarPlay or Android Auto has occasionally been problematic, with users experiencing disconnections or delays. Updating both the smartphone and infotainment system can resolve these issues.

Brake System Anomalies

Some owners have reported concerns with the Highlander’s brake system. A spongy brake pedal feel, which reduces responsiveness, is a common issue. This is often caused by air in the brake lines or degraded brake fluid. A professional brake bleeding service can address this.

Unusual brake noises, such as squealing or grinding, are another concern. These are typically signs of worn brake pads or rotors. Regular inspections and timely replacements can prevent these noises from escalating into more serious issues.

Suspension and Handling Challenges

The suspension and handling of the 2020 Toyota Highlander have raised some concerns among owners. Some have noted a bumpy or less comfortable ride, particularly on uneven roads. This is often linked to worn or improperly adjusted shock absorbers and struts. Regular maintenance of these components can improve ride quality and stability.

A vague or loose steering feel has also been reported. This may result from misaligned wheels or worn steering components. A professional alignment and inspection of steering linkages can address this issue. Monitoring tire condition and pressure is also important for maintaining optimal handling and suspension performance.

By addressing these common issues proactively, owners can ensure a smoother and more reliable driving experience with their 2020 Toyota Highlander.
