2024 Toyota Highlander Reliability Score & Common Problems

Owners of the 2024 Toyota Highlander frequently report issues with the electrical system, particularly concerning the instrument cluster and infotainment screen failures. Common symptoms include the instrument panel failing to display critical information, center screens blacking out, and inaccurate GPS navigation. These issues often occur at various mileage points, with some complaints noting problems as early as 1,000 miles. One complaint involves a crash due to an uncontrollable surge, highlighting potential safety concerns. Used car buyers should be aware of these electrical issues, especially since some complaints mention extended repair times due to parts unavailability.

Owners of the 2024 Toyota Highlander commonly report issues with the fuel system, particularly related to the fuel tank not filling to its stated capacity. Complaints frequently mention that the vehicle's fuel tank, advertised as holding around 17 gallons, only accepts 11 to 14 gallons even when the gauge indicates empty. This discrepancy leads to reduced driving range, often around 230-340 miles per fill-up, contrary to the expected 400+ miles. Additionally, multiple owners describe a strong gasoline odor, particularly after driving in hot weather, with some expressing concern about potential safety hazards such as fuel vapors in enclosed spaces like garages. These issues are noted across various mileage ranges and suggest a consistent pattern among new Highlander models.

Owners report that the 2024 Toyota Highlander experiences significant acceleration delays, particularly from a complete stop, with many describing a 2-5 second hesitation before the vehicle responds to the accelerator pedal. This issue frequently occurs in vehicles with less than 9,000 miles and is often described as a "dead pedal" situation where the engine fails to rev or engage. Complaints also mention instances of sudden, excessive acceleration following the initial delay, sometimes leading to near-miss accidents or loss of control. These symptoms pose safety risks, especially in traffic or when crossing intersections, as the vehicle's unpredictable response can leave drivers vulnerable. Multiple attempts at dealership repairs, including software updates, have been reported as ineffective in resolving the issue.

Owners report two primary issues with the 2024 Toyota Highlander's suspension. The first issue involves a popping or clicking noise when turning, often linked to faulty CV axles. This problem sometimes emerges as early as 2,162 miles, with multiple reports of axle replacements needed. The second issue is a low-frequency cabin noise described as a "boom" or "acoustic boom," causing discomfort such as headaches and nausea, particularly at speeds under 50 mph. While no crashes or loss of control are reported, the symptoms can be distracting and uncomfortable. These complaints highlight potential safety and comfort concerns for prospective buyers.

Owners of the 2024 Toyota Highlander frequently report issues with the braking system, particularly a sensation of pulsing or inconsistent braking at low speeds, which some attribute to the interaction between regenerative and conventional braking. Multiple complaints describe the car lurching forward unexpectedly when brakes are applied, with some owners experiencing a temporary loss of braking effectiveness until the pedal is nearly fully depressed. Additionally, unintended braking while reversing and a hopping sensation when stopped are noted by some drivers. These issues often occur without warning lights or error messages, and service centers have struggled to replicate the problems. Safety implications include potential near-misses and the risk of accidents, as several owners express concerns about the vehicle failing to stop as intended.

Owners report a recurring issue with the 2024 Toyota Highlander's steering system, specifically related to the CV axles. Complaints frequently mention a clicking or popping noise when turning the steering wheel left or right, with some noting the noise becomes more pronounced over time and mileage, particularly around 30,000 to 47,000 miles. Multiple owners describe having CV axles replaced, sometimes multiple times, yet the noise persists. While some owners express concern about potential safety risks if the CV joint fails, there are no reports of crashes or loss of vehicle control directly linked to this issue. This information may be useful for used car buyers considering the model, as they might encounter similar symptoms.

Owners report issues with the 2024 Toyota Highlander's engine, primarily involving acceleration hesitation and shifting difficulties. Multiple complaints describe a delay or lack of power when accelerating from a stop, with some noting high engine revs at low speeds. Additionally, there are reports of hybrid system malfunctions linked to debris damage through the front grill, affecting internal components like the radiator and condenser. These problems are noted as early as 2,300 miles, with some owners experiencing significant engine damage, including cylinder disintegration. No crashes or loss of control are mentioned, but the described issues could impact vehicle performance and reliability.
