2021 HONDA ACCORD Complaints

Since the first winter after I purchased my vehicle in 2021, typically when cold, but not always, I lose all the Honda Sensing (Advanced Driver Assist Features). The dashboard lights up with the following warnings . - Collision Mitigation Braking System Problem. See Dealer - Road Departure Mitigation System Problem. See Dealer - Auto High Beam Problem. See Dealer - Adaptive Cruise Control System Problem. See Dealer - Lane Keep Assist System Problem. See Dealer This failure of these safety systems can last anywhere from 5-60 minutes. Sometimes if you shut the vehicle off and turn it back on again, the warning will go away. On multiple cold mornings (below ~45°F), my 2021 Accord Hybrid displays a cascade of safety system failure warnings upon startup. The dash shows errors for the collision mitigation braking, lane keeping assist, adaptive cruise control, road departure mitigation, and more—all at once. When these systems are disabled, it severely compromises safety. This issue happens repeatedly in colder weather. The dealer has personally witnessed the issue in their service bay and acknowledged it's a known problem but had no fix, advising me to turn the car off and on again. This recurring failure of critical safety systems in cold conditions puts me, my passengers, and other road users at risk.

Lanes on the roadway were adjusted for a workzone. Because of these lane adjustments, a large amount of crack sealer was used on the roadway. The car confused the crack sealer as roadway markings and tried to slam on the brakes in a workzone, thinking I was going over the lines, unless I used the turn signal to override the automatic braking, which is the only way I was able to avoid getting rear-ended. This ian't the first time this ecent has occurred in my vehicle.

There is a current recall on my vehicles make and model for the fuel system but my vin is showing as not affected and am currently experiencing issues.

Car says “brake system problem, brake performance may be reduced. See your dealer” and then another one saying “brake hold system problem. Apply brake when stoped. See your dealer” and another one that says “Electric parking brake system problem. Parking brake not available. See your dealer.” And I know quite a few people with accords that are having this issue as well!

If im driving at normal rate of speed while on highway the steering becomes very loose and sticky when adjusting steering. The passenger wheel will feel like it wobbles on its camber axis or will act like a shopping cart wheel. At times changing direction of vehicle entirely. At that time suspension will feel really spongy.

On 3 occasions, was accelerating on interstate (after entering from ramp), check engine light began blinking, car shook terribly & went into limp mode - gas pedal was to the floor but car continued to lose power. Had to pull off road - turned car off, waited 20 minutes, turned car back on - check engine light went off & car was drivable. Another time, while accelerating on interstate, check engine light started blinking & all warning lights came on flashing. Car began losing power - had to pull off on side of the interstate - car was towed to the dealership. Another time, was pulling off from a light on highway - I accelerated, check engine light began blinking, car shook terribly & went into limp mode, requiring me to pull off on side of the highway - turned the car off for 15 minutes - turned it back on, light was off & was able to drive car. Most recent incident - was accelerating on small, 2 lane highway - check engine light began flashing & car shook terribly but didn't go into limp mode - otherwise behaved as before. Each time, took the car to the dealer ASAP to report problem. First time, was told they had to fix broken tail light b/c it was throwing off system & they couldn't get a computer reading. Once done, was told that they got a "CYL2 Miss Fire Code. Performed diagnosis on code. Diagnosis led to improperly adjusted valves. Performed valve adjustment. Found half of valves loose and half tight." Was road tested - no further concerns noted by dealer. Other times, was told that computer wasn't showing any codes. Last event literally happened in front of Advance Auto - pulled in/hooked up to check code - indicated a Cyl 2 misfire. Took to dealer - said no code showing - berated me for having checked @ Advance - said it erased any codes, even though I told them the code that was noted. This is a serious safety issue due to car going limp when accelerating on interstate where others are going 70-90 mph. Dealer says nothing they can do d/t no code showing.

@ 96,970 miles, (2021 Honda Accord Hybrid) when getting on the freeway and accelerating to catch up with traffic, the car began sputtering, the check engine light flashed, the accelerator stopped working and I had to get it to the shoulder of the freeway immediately. The car sputtered and shook. I turned the car off, let it sit. I tried re-starting it and it started fine, no check engine light. I drove it slow off the freeway and to my home close by. I got it to the dealer. The Service Rep said he had never heard of this issue although it does appear on Honda Forums. He said no codes showed and decided it needed a Cylinder adjustment and then decided it also needed a new (refurbished) transmission. It was in the shop for weeks. I've tried warming the car up longer and using more expensive gas. Issue continues to happen. I called an made an appointment at the dealer for first available date. Today I had it checked for codes again from a different mechanic and the mechanic said it has no codes - at all. Fluids all perfect, no issues with coolant levels. All maintenance has been completed on schedule. I did video tape my dash when it happened Wednesday, on I80, 3/5/25 12:12pm.
