2020 Honda Accord Problems

What owners report

Owners of the 2020 Accord most often report two very different things: the driver-assist system braking or warning on its own at highway speed, and various problems that cause the engine or fuel system to cut power. Complaints arrive across the mileage range — the driver-assist and brake reports often show up on low-mileage cars, while engine and fuel-pump reports tend to come in later, past 50,000 miles. Several complaints also describe transmissions or steering behaving oddly in ways dealers could not reproduce.

1. 1
   Fuel system

   Loss of power and stalling (engine and fuel system)

   • 47 complaints (13%)
   • median 66,500 mi at 5.2 yrs old (18 state mileage)
   • filed 2020–2026

   Owners report the engine cutting out or falling into limp mode while driving, sometimes with a shudder or violent shake beforehand, and several describe being unable to restart the car. Dash lights often come on together and the dealer may point to the low-pressure or high-pressure fuel pump; some owners were told their VIN was not covered by the fuel pump campaigns. Others describe rough idling, misfires on specific cylinders, a strong fuel smell in the oil, or stalling that the dealer could not pin down. Mostly reported between roughly 30,000 and 75,000 miles, with a few cases earlier and a few past 100,000 miles.

   What to check: Have the fuel pump recall history checked by VIN and ask for service records of any fuel pump or injector work. Listen for rough idle or hesitation on a cold start and check the oil for a fuel smell.

   “High pressure fuel pump Yes almost caused an accident Vehicle was inspection and replaced No warning at all just lost power and all lights came on the dash. I was traveling in left lane down the highway lost power had to cross 3 lanes to get right side of shoulder. I shut off the car when I stop on the shoulder . I inspected the car for sign of low oil or coolant I didn't see any reason I lost power without any notice . …”

   Forward collision avoidance

   Automatic emergency braking engages with nothing ahead

   • 116 complaints (32%)
   • median 11,500 mi at 2.0 yrs old (26 state mileage)
   • 5 mention a crash, fire or injury
   • filed 2020–2026

   Drivers describe the collision mitigation braking system applying the brakes on its own, sometimes briefly and sometimes slowing the car sharply, on open highway with no vehicle ahead. Along with the braking, dash messages such as "Collision Mitigation Braking System problem" and "Adaptive Cruise Control problem" appear, and cruise control may slow the car unexpectedly. Complaints also describe lane departure warnings firing unprompted; dealers typically could not reproduce the condition, told owners to clean the sensors, or said the repair was not covered. Reported from a few hundred miles up to roughly 60,000 miles, usually at highway speeds in clear weather.

   4 related service bulletins

   What to check: Ask whether the Honda Sensing software update described in the service bulletins has been applied, and confirm the car has been driven at highway speed with adaptive cruise on during a test drive. Note any stored or recurring ADAS warning messages.

   “The automatic braking system was activated when I was driving ~40mph on a straight highway under clear weather conditions with no cars in front of me. Fortunately, the car behind me was able to avoid me but I did receive a few honks and a couple of finger salutes. I immediately reported the problem to my dealership and still haven't heard from them - 4 hours and counting.”

   NHTSA complaint #11407256, filed 2021-04, 7,200 miles

   “Constant alert coming on vehicle as driving saying collision mitigation braking system has a problem. Have your vechile checked by dealer along with adaptive cruise controm system has problem. Turn off engine, then restart am I dealing with a computer or a vehicle I can potentially lose my life if something goes wrong???”

   Brakes

   Rear brakes and rotors wearing unevenly or shaking

   • 47 complaints (13%)
   • median 9,000 mi at 1.5 yrs old (16 state mileage)
   • filed 2020–2026

   Complaints describe vibration and squealing when braking, with rear rotors diagnosed as warped and needing replacement at very low mileage. Some owners say the rear pads were already heavily worn within a few thousand miles and link it to frequent stability-control intervention. Others describe a soft or unusually hard pedal, a "Service Brakes" message, or a brake booster that needed replacement after repeated dealer visits. Often reported under about 12,000 miles, in a few cases within the first few thousand miles.

   What to check: Inspect rear pad thickness and rotor surface on any used example, and feel for pedal pulsation or shudder during a test drive. Ask whether rotors have already been replaced.

   “With only 2600 miles on the car, I went in for a inspection at Honda and the rear brakes were already fading to the point that I might need to replace them within 2k more miles. From what I read, the stabilizing feature that Honda implemented is a bit too aggressive and because of that the rear brakes are wearing out much faster than they should.”

   NHTSA complaint #11408528, filed 2021-04, 2,664 miles

   “I was driving on the highway going 65 MPH and all of a sudden my car brakes came on while I still had my foot on the gas pedal. Luckily for me there where no cars behind. I have schedule an appointment with Honda service depart first thing tomorrow morning. I just purchased my Honda Accord 2020 vehicle a month ago.”

   Steering

   Steering flat spot or wandering at highway speed

   • 22 complaints (6%)
   • median 9,000 mi at 1.4 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2020–2026

   Drivers describe a notch or flat spot in the steering when cruising straight, so the car drifts slightly before the wheel catches and requires constant small corrections. Some report the wheel sticking when turning slightly and then releasing, causing overcorrection. Owners say dealers could not recreate the condition; one complaint describes the power steering pulling the car toward the curb. Reported from a few hundred miles upward, most often after 20–45 minutes of continuous highway driving.

   What to check: Take a longer highway test drive at steady speed and feel for a dead spot or stickiness around center. Ask whether a steering rack or alignment issue has already been inspected.

   “8/31/2020 my 2020 Honda Accord power steering is taking control of power steering. I had a crash at 400hampton road -dallas texas. My ( power steering) pulled to the left side of the curb, I had to yank the car back to the left but the car already collided with the left curb, resulting in property damage to the side of car and my right hand.”

   NHTSA complaint #11405999, filed 2021-04, 9,000 miles

   “There appears to be an issue with electronic power steering when driving straight, the power steering will lack response and the car will drift only to have control regained via a notchy light jolt of the wheel. Another way in which 2018-2020 Accord consumers have described it as a notch and/or flat spot in the steering when on smooth straight highway roads. As other consumers have noted, I typically encounter this only after driving for a significant amount of time, but I do even notice this within 20-30 minutes of driving. …”

   Air bags

   Air bag and passenger sensor warnings

   • 34 complaints (9%)
   • median 71,000 mi at 5.0 yrs old (5 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2020–2026

   Owners report the air bag or SRS warning light coming on, sometimes alongside a message directing them to the dealer, and diagnosis points to the front passenger seat sensor or an air bag needing replacement. Some complaints mention air bags deploying without an impact. Several owners tie the warning to the front passenger occupant sensor recalls. Mostly reported between about 50,000 and 75,000 miles.

   Recall 24V064000Recall 26V332000

   What to check: Check that the front passenger occupant sensor recall has been completed by VIN, and confirm the SRS light goes out normally after the car starts.

Buying note. These reports are a mix of software-driven warnings and mechanical wear, so a scan for stored codes and a long highway test drive with the driver-assist features switched on tell you more than a short spin. Ask for the recall and service-bulletin history by VIN, especially for the fuel pump and passenger seat sensor campaigns.
