The infotainment system in these vehicles is poor when using the navigation. Having the phone connected via wire will cause the phone and infotainment system to malfunction constantly causing restarts and making the mobile device extremely hot too the touch. The android auto function in the car loses connection and begins to cause the arrow marker to jump around on the map causing confusion, turn directions down wrong roads causing drivers to enter areas of no thruway due to a business being there. Researched this for 2 years and there is no current fix from HONDA other owners through REDDIT have the same issue and have been told by HONDA that nothing can be done to fix the hardware system.

A recent Electric Power Steering (EPS) failure on my 2021 Honda Civic that resulted in a repair of the entire steering rack. I took my vehicle to Vandedrgriff dealership for routine maintenance, including tire replacement, alignment, oil change, and a multi-point inspection. The car passed all checks and was deemed safe to drive. However, immediately after leaving, the steering became sticky and difficult to control on the freeway — a serious safety risk. Upon returning the next day, I was informed of an internal EPS failure, with a repair estimate exceeding $4,584.30. I later discovered this failure involves a part number tied to a known Honda recall. Although my VIN is not currently part of the recall, the symptoms and overall failed part match exactly. The failure occurred immediately after authorized dealership service without warning. The EPS unit is associated with a known defect. The failure occurred just outside the 3-year warranty and before its time. An EPS is guranteed good over 100,00 miles. The issue created a dangerous situation on the road. Honda America Corporate has inspected the vehicle and refused to cover the repair because I am right outside of my warranty. I am a loyal Honda customer and trust in Honda's commitment for safety and customer satisfaction.

While driving at interstate speeds and turning left into a curve the steering wheel sticks and you have to forcibly pull it back to drive straight jerking the vehicle dangerously. Possibly a known steering rack issue.

At higher speeds the steering wheel sticks, this make making minor corrections to stay within the lane difficult, subsequently causing the vehicle to swerve while making these adjustments.

The component that has failed is my electric power steering motor. Yes, it is available for inspection upon request. While driving, the steering wheel should turn in a fluid motion, without requiring much force to turn the wheel. When i turn my wheel, it sometimes will get stuck mid turning. Another time when this happens is when i am driving in a straight line. Making the micro adjustments to stay straight in between the lines. The steering wheel will catch, and i will have to exert additional force to get the wheel unstuck. Obviously, this has caused safety issues, as sometimes the strength to overcome the wheel being stuck will cause me to oversteer. This has also been found to be a problem on some 2022 and 2023 year Civics. There is already a recall for this problem, but not for my year civic. It does greatly lower my safety while driving, when i should never be uncomfortable in my own car. The problem has been confirmed by my own mechanic, and by Honda. It has been inspected by my own mechanic as well. There were no indications on the dash to warn me the motor was going to fault. I do not remember the exact date it happened, but sometime last week when i took my car in to have the CV joints replaced. The problem has steadily gotten worse since then.

With my steering wheel, when turning, the wheel will sometimes get “sticky”. Making it so I have to use extra force to get he wheel “unstuck”. Took it to my mechanic, they found a recall for the ‘22-‘23 year model civics for this same problem. The electric steering motor can sometimes fault and cause the wheel to get stuck while turning.This was not for the ‘21 year. I called my dealership, they said there was nothing I could do as there is no recall for my vin, although I’m having the exact same problem as the ‘22-‘23 models. He recommended I can the Honda 1-800 number. Pretty much got told the same thing. I was looking to get a goodwill extension, he said that would not apply due to Honda warranties. Next best thing was for me to be here filing a complaint.

I was informed of a recall notice for my vehicle in the summer months of 2024 (approximately). I took my vehicle to the Culver City Honda dealership in Los Angeles to address this, however they informed me that the issue was not critical and that they did not have the parts. Hence, the recall notice has still not been addressed. I recently (June 2025) imported this vehicle to Canada and I am unable to proceed with the import procedure because of this outstanding recall notice.

Steering has progressively become more "sticky", hitching around 12 o' clock. It gets worse at higher speeds and makes it difficult to drive in straight line, and I end up bouncing back and forth between lane lines when driving on highway.

Our battery died in April 2025. We've had this car since October 2021 with only 8 miles on it. We've replaced: The PCV valve The PCV valve tube The MAF sensor The sparks plugs 3 times which was $90 each time Replaced our battery 2 times since April 2025 3 oil changes And finally replacing our entire fuel injector system with the hard fuel line. And replacing the battery the first time is what revealed all these issues because we kept getting codes on our obd-ii scanner of P0172, U0038 and U0100. Honda told us once the fuel injectors were replaced then our car would be fixed but that is not the case. The car can't travel further then 5 minutes before the spark plus burn. We replaced the spark plugs on Sunday morning and we went to the store and they were charred after that drive same day.

Steering of the car at highway speeds is impaired. The steering becomes sticky and hard to control, both hands need to be tightly gripping the steering wheel in order to keep the car under control as it comes and goes and one cannot anticipate the reaction of the car. Steering should be smooth and not jerky, this creates an exhausting and unsafe occurrence. I have taken the car to two different Honda dealers, the one where I purchased the vehicle and a larger well known dealer an hour and a half from my home. Attached is the most recent inspection report and cost breakdown. Roush Honda offered to contact Honda directly regarding this inspection, issue and recommendation. There were no warning lamps or messages. This issue started a little over 30 days ago. It has taken some time to get it into the two different Honda locations to get an inspection.

While driving my 2021 Honda Civic Sport, both front airbags deployed without warning and without any accident or impact. There were no warning lights beforehand, and no collision occurred. The deployment also caused my windshield to crack. After the airbags went off, the dashboard displayed a ‘SRS airbag system problem’ message. This is a serious safety concern as the vehicle was operating normally at the time. I’m requesting that this be investigated as a potential manufacturer defect

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Honda Civic Si verdict →
