2024 Toyota Grand Highlander Reliability Score & Common Problems

Owners report multiple electrical system issues with the 2024 Toyota Grand Highlander, primarily involving the infotainment screen going black and instrument cluster failures. Complaints frequently mention screens losing functionality, including maps and radio, with some instances requiring a vehicle restart to restore operation. Instrument cluster failures are noted, with some vehicles becoming unsafe or inoperable, often linked to recall-related issues with no available remedy. Typical symptoms occur at various mileage ranges, with some reports at approximately 1,000 miles and others at higher mileages, such as 90,000 miles. Safety implications are significant, as the loss of critical display information can affect driving safety, and the inability to start or access the vehicle due to key fob detection failures is also noted.

Owners of the 2024 Toyota Grand Highlander frequently report issues with the vehicle's fuel system, primarily concerning the inability to fill the fuel tank to its advertised capacity. Many complaints mention that the tank only accepts 11 to 14 gallons, despite the vehicle specifications indicating a 17-gallon capacity, leading to reduced driving range and more frequent refueling. Additionally, some owners describe a persistent gas odor, particularly in hot weather, which raises potential safety concerns regarding vapor accumulation. These issues are often noted within the first year of ownership, with some owners referencing a lack of resolution from Toyota service centers. This information suggests prospective buyers should be aware of potential refueling inconvenience and the need for frequent monitoring of fuel levels.

Owners report frequent issues with the 2024 Toyota Grand-Highlander related to vehicle speed control, primarily involving hesitation and delayed acceleration from a stop. Complaints frequently mention a "dead pedal" experience where the vehicle does not respond for several seconds, followed by a sudden surge in acceleration. This issue often occurs when stopped at intersections or during left turns, posing a safety risk due to potential collisions. No warning lights or error messages typically accompany these incidents, and several owners note that dealership visits have not resolved the problem. The issues are reported both shortly after purchase and at mileage as low as 8,000, indicating a potential early onset of this problem.

Owners of the 2024 Toyota Grand-Highlander frequently report issues related to the suspension, with two primary complaints emerging. First, several owners describe a knocking or popping noise when turning, which in some cases leads to the replacement of the CV axles, often at low mileages such as 2,162 to 20,000 miles. Second, multiple complaints mention a low-frequency cabin boom or reverberation noise occurring at speeds below 50 mph, causing discomfort such as ear pain and nausea. Safety concerns are noted by some owners due to the vehicle's instability, such as sliding or wobbling, though no crashes or loss of control incidents are reported. These issues may be of interest to potential buyers considering the vehicle's early-life mechanical challenges.

Owners report that the 2024 Toyota Grand-Highlander frequently experiences a clicking or popping noise when the steering wheel is turned left or right, often attributed to CV axle issues. Complaints typically describe this noise as originating from the front of the vehicle, particularly noticeable during turns, and some owners note that the problem persists or worsens over time, even after axle replacements. The issue is commonly reported to occur at mileage under 30,000, with some cases extending up to 47,000 miles. While some owners express concern about potential safety implications, such as loss of vehicle control, there are no reports of crashes or other direct safety incidents. Buyers should be aware of this recurring issue and may want to verify if any repairs have been performed on the CV axle when considering a used purchase.

Owners report several issues with the 2024 Toyota Grand-Highlander’s engine. A common pattern involves damage from road debris penetrating the front grill, leading to hybrid system malfunctions and radiator or AC condenser damage, which Toyota does not cover under warranty. This damage typically occurs at low mileages, such as 2300 miles, and is attributed to a perceived design flaw in the grill. Additionally, multiple owners describe hesitation or lack of power when accelerating from a stop, and issues with shifting and high engine revs at low speeds. While no crashes or fires are reported, these symptoms may affect vehicle performance and reliability.

Owners of the 2024 Toyota Grand-Highlander report two distinct issues related to the service brakes. One pattern involves unintended braking, particularly in reverse, with at least three instances noted, and one occurrence while driving forward. Dealerships have been unable to resolve this issue, according to the reports. Another issue involves a hopping sensation when the vehicle is at a complete stop, described as similar to a manual transmission vehicle not shifting correctly. This has been reported to occur intermittently since December 2024, with no resolution found by dealerships. No crashes or loss of control are mentioned in the complaints, but these symptoms could potentially impact driving safety.
