2021 Honda Accord Reliability Score & Common Problems

Owners of the 2021 Honda Accord frequently report issues with the vehicle's automatic braking system engaging unexpectedly, even in the absence of obstacles, leading to sudden stops and potential rear-end collisions. Several complaints involve the Collision Mitigation Braking System (CMBS) activating without cause, with some incidents resulting in crashes. Additionally, multiple owners describe persistent brake noise, particularly when reversing, and some report brake components wearing prematurely, often at mileages as low as 5,000 miles. Safety implications are evident, with three reported crashes linked to abrupt braking. These patterns suggest potential risks for used car buyers considering this model.

Owners of the 2021 Honda Accord frequently report issues related to airbag recall repairs, noting significant delays in the availability of parts necessary for these repairs. Complaints consistently mention that despite receiving recall notifications, the parts needed are not available, leading to prolonged waiting times that some owners claim extend up to several years. One report involves a crash where the airbags did not deploy, although no injuries were reported. Additionally, a diagnostic test in one case revealed a faulty airbag supplemental restraint system, potentially affecting airbag deployment during a crash. These issues are reported by owners at varying mileage, with one specific mention at 38,000 miles. This information may be relevant for potential buyers considering the safety and maintenance history of this vehicle model.

Owners report that the 2021 Honda Accord frequently experiences engine issues characterized by flashing check engine lights, engine misfires, and loss of power, often leading to limp mode. Symptoms often occur during acceleration, with some incidents involving rough idling, sputtering, and vehicle shaking. Several complaints indicate head gasket failures, particularly in vehicles with mileage ranging from 50,000 to 100,000 miles. A significant number of owners mention that these issues can result in unsafe driving conditions, especially at highway speeds, and one report describes a crash involving unintended acceleration. Buyers considering a used 2021 Honda Accord should be aware of these potential engine reliability issues and their associated safety risks.

Owners report frequent issues with the lane departure systems of the 2021 Honda Accord, particularly in cold weather and direct sunlight. Complaints frequently mention the Lane Keep Assist System (LKAS) erroneously activating or deactivating, causing the steering wheel to jerk, which can lead to difficulty in maintaining lane position. These symptoms are often noted shortly after purchase and can persist over time, with some reports indicating occurrences as early as 3,000 miles and others at higher mileages around 60,000. Safety implications include potential loss of control, with some owners describing near-miss situations due to the system's unexpected behavior. This information is crucial for potential buyers who may prioritize vehicle safety and reliability in varied weather conditions.

Owners report frequent issues with the head gasket in the 2021 Honda Accord, leading to sudden power loss and dashboard warning lights activating without prior indication. These failures often result in the vehicle shutting down unexpectedly, with one reported crash and two injuries linked to this problem. Complaints suggest these incidents can occur at both high speeds on highways and lower speeds in local traffic. Additionally, some owners mention problems with the vehicle's throttle response and steering wheel shaking, particularly at speeds of 60 to 65 mph. These issues pose significant safety risks, especially in heavy traffic or adverse weather conditions, and should be considered by potential buyers.

Owners report multiple steering-related issues with the 2021 Honda Accord, often involving unexpected vehicle behavior. Common symptoms include the steering wheel jerking unexpectedly, sometimes triggering lane changes, and a loss of power steering functionality, particularly at low speeds. Several complaints describe steering becoming loose or sticky, leading to a loss of control, with some incidents resulting in crashes and injuries. These issues are reported across a range of mileages, with some occurring as early as 564 miles. Safety implications are significant, as multiple crashes and two injuries are noted, highlighting potential risks for used car buyers.

Owners of the 2021 Honda Accord frequently report issues with the vehicle speed control, including unexpected loss of power and unintended acceleration. Typical symptoms include the vehicle decelerating or losing power while driving, often accompanied by flashing engine lights, and in some cases, the vehicle accelerating uncontrollably. These issues are reported at various mileages, with some incidents occurring as early as 17,000 miles. Safety implications are notable, with one complaint involving a crash when the vehicle accelerated suddenly, leading to a collision with a parking sign. These patterns suggest potential safety risks, especially in congested or high-speed environments.
