The 2018 Honda Accord uses electric power steering (EPAS) and some owners have reported intermittent or total loss of steering assist due to EPS faults; Honda has issued recalls and service bulletins for affected vehicles, with fixes that can include software updates or replacement of EPS components.
In more detail, the EPAS system uses an electric motor and control unit to provide steering assist, guided by sensors and software. When the system detects a fault, it may illuminate an EPS warning light and reduce or remove steering assist, which can make steering heavier and more difficult, especially at low speeds. The issue is not universal to all 2018 Accords, but it has been reported enough to prompt recalls and service actions in some VINs. Below is what owners, buyers, and technicians should know about symptoms, causes, and remedies.
Understanding the EPAS system in the 2018 Accord
Electric power steering differs from older hydraulic systems in that it relies on an electric motor and electronic control rather than hydraulic fluid pressure. In the 2018 Accord, the EPAS unit works with a steering-angle sensor and a control module to determine how much assist to provide during steering inputs. When a fault is detected, the system may limit or disable assist to protect the vehicle and occupants, prompting service action.
Common symptoms of EPS problems
Owners reporting EPS-related issues typically notice a mix of steering feel changes and warning indicators. The following signs are commonly described in reports and service bulletins.
- Steering feels heavy or stiff at low speeds or when parking
- EPS or Power Steering warning light illuminated on the dashboard
- Unusual noises (rattling or groaning) from the steering area
- Intermittent or permanent loss of steering assist
- Unpredictable steering response or delayed input feel
If you experience any of these symptoms, it is important to diagnose the EPS system promptly, as even temporary loss of steering assist can create a safety risk in traffic.
Causes and contributing factors
Several factors can contribute to EPS failures in the 2018 Accord. While the exact cause can vary by vehicle and VIN, common contributors include:
- Faulty EPS motor or torque sensor in the steering column
- Damaged or corroded wiring harnesses or connectors within the EPAS system
- Software glitches or calibration issues in the EPAS control unit
- Electrical supply instability, such as battery or alternator voltage fluctuations
- Body or age-related wear that affects connectors or sensors
Because EPS faults can stem from hardware or software, the resolution may involve different service approaches depending on the root cause.
Diagnosis and typical fixes
When EPS problems surface, a dealership or qualified shop will typically perform a diagnostic scan to pull fault codes from the EPAS control unit and associated modules. Based on findings, common remedies include the following:
- Software update or reprogramming of the EPAS control unit
- Calibration or replacement of the torque sensor
- Replacement of the EPS motor or steering column assembly
- Repair or replacement of damaged wiring or connectors
Repair costs and coverage vary by vehicle age, mileage, and warranty status. If the vehicle is under Honda’s warranty or a recall coverage, some or all of the fixes may be covered.
Recalls, service bulletins, and how to check your vehicle
Honda and the regulatory authorities have issued recalls and service notices for EPS-related issues on some 2018 Accord models. Because eligibility depends on the specific VIN, it is essential to verify the status of any recall or Technical Service Bulletin (TSB) for your car.
- Check the National Highway Traffic Safety Administration (NHTSA) recall page and enter your VIN to see active or completed recalls related to EPS
- Consult Honda’s official recalls portal or contact a local dealer with your VIN for a precise service history
- Ask the dealer to review any related Service Bulletins (TSBs) that may apply to EPAS software or hardware calibration
Owners who have experienced EPS warnings should have service arranged promptly to avoid driving with an unreliable steering assist system.
What to do if you own or are considering buying a 2018 Accord with EPS concerns
For current owners, steps to take are straightforward and safety-focused. For potential buyers, verifying the EPS status can inform the purchasing decision.
- Verify recall status and service history using your VIN on NHTSA’s recall lookup or Honda’s recall portal
- Schedule a diagnostic check with an authorized Honda service center or a shop experienced with EPAS systems
- Ask for a software update if applicable, and request a diagnostic report detailing any fault codes and recommended repairs
- If repairs are required, have them performed before long-term ownership, as unresolved EPS faults can compromise steering reliability
In all cases, avoid driving with a known EPS fault if the steering becomes unresponsive or heavy, and seek immediate service to restore full steering assist and vehicle safety.
Summary
The electric power steering system in the 2018 Honda Accord is designed to improve efficiency and road feel, but it can develop faults that lead to intermittent or permanent loss of steering assist. Symptoms include a heavy steering feel, warning lights, and unusual noises. Causes range from motor or sensor failures to wiring issues and software glitches. Diagnosis typically involves diagnostic scans and may result in software updates or component replacements. Recall status and service actions depend on your vehicle’s VIN, so checking official recall databases and consulting a Honda dealer are essential steps for owners and prospective buyers alike.
