2018 Honda Odyssey Reliability Score & Common Problems

Owners report that the 2018 Honda Odyssey frequently experiences failures in its forward collision avoidance systems, primarily due to issues with the front-facing monocular camera. Typical symptoms include multiple dashboard warnings for adaptive cruise control, lane keeping assist, collision mitigation, and other safety features, often occurring without prior indication. Complaints suggest these issues can emerge at varying mileages, including some vehicles with low mileage. Notably, two complaints involve crashes, highlighting potential safety implications when these systems fail. Potential buyers should be aware that resolving these issues may involve significant repair costs, as reported by some owners.

Owners of the 2018 Honda Odyssey frequently report issues with the power tailgate and sliding doors, often linked to water intrusion and sensor malfunctions. Complaints describe tailgates failing to latch or open unexpectedly, and sliding doors that do not reverse when obstructed, posing potential safety risks, especially to children. The Auto Engine Idle Stop system is another common concern, with reports of the engine stalling or failing to restart at intersections, sometimes accompanied by multiple dashboard warnings. Transmission problems, such as delayed acceleration and unexpected disengagement, are also noted, with some incidents leading to crashes. These issues often appear in vehicles with mileage under 50,000, and prospective buyers should be aware of potential safety implications and repair costs associated with these problems.

Owners report frequent issues with the 2018 Honda Odyssey's sliding doors and tailgate, often linked to water intrusion and faulty components. Complaints commonly describe sliding doors that intermittently fail to open or close, sometimes unexpectedly unlatching while driving, with some reports mentioning repeated dealership visits for repairs that do not fully resolve the issues. Tailgate problems are frequently associated with water damage to the control module, leading to non-functional tailgates and sporadic opening or closing. Several owners note these problems occurring at various mileage points, with some mentioning issues persisting despite recall repairs. Safety implications include potential entrapment due to door failures and risk of injury from doors or tailgates opening unexpectedly. These patterns suggest prospective buyers should thoroughly inspect these components and verify any recall work.

Owners of the 2018 Honda Odyssey frequently report issues related to the fuel pump, with common symptoms including engine hesitation, difficulty accelerating, and stalling, particularly during merging or starting from a stop. Many complaints highlight problems with both high and low-pressure fuel pumps, often occurring around or after 80,000 miles. Safety implications are notable, as some owners describe situations where the vehicle unexpectedly loses power or stalls, leading to hazardous driving conditions. Additionally, one report involves a crash, and several owners express frustration with recall-related delays and inadequate dealer responses, which leave the issues unresolved and vehicles potentially unsafe.

Owners of the 2018 Honda Odyssey frequently report issues with vehicle speed control, particularly hesitation and delayed acceleration from a stop or low speed. Complaints describe scenarios where pressing the accelerator results in no immediate response, followed by a sudden burst of speed, often causing the tires to spin. This issue is commonly noted when making turns or merging into traffic, with reports mentioning occurrences at various mileage points, including as early as 40,000 miles. These acceleration delays are cited as creating dangerous situations, with one injury reported due to near-miss collisions. Additionally, several complaints highlight failures in the vehicle's safety systems, such as adaptive cruise control and lane assist, often linked to issues with the front-facing camera, which some owners note began after a battery replacement. These symptoms suggest potential safety concerns for prospective buyers.

Owners of the 2018 Honda Odyssey frequently report issues with the vehicle's automatic emergency braking system, particularly the Collision Mitigation Braking System (CMBS), which engages unexpectedly and without obstacles present. This often occurs during turns or at intersections, leading to abrupt stops that risk rear-end collisions. Complaints also describe a soft or low brake pedal, which affects braking performance and requires more effort to stop the vehicle. Several reports mention these issues arising at various mileage points, with some occurring as early as 2,000 miles. One incident involved a crash with three injuries, highlighting significant safety implications related to these braking problems.

Owners report that the 2018 Honda Odyssey frequently experiences unexpected airbag deployments without any impact or external trigger, often while driving on normal roads. Complaints commonly describe the sudden and loud deployment of airbags, which can startle drivers and potentially impair vehicle control. In several cases, this issue has led to crashes and injuries, with airbag systems failing to deploy during actual collisions or deploying unnecessarily in minor incidents. The reported mileage at the time of these incidents varies, with some occurring at over 100,000 miles. Prospective buyers should be aware of these airbag system concerns, as they pose significant safety implications, including potential injuries and increased repair costs.
