Filed Sep 20, 2026 · Electrical, Steering · CA

On September 17, 2026 at approximately 8:00 a.m. I was driving my 2021 Honda civic Lx with my children in the vehicle when multiple warning lights and system malfunction messages suddenly appeared on the dash board. The vehicle appeared to experience an electrical malfunction/ reset while still driving and I suddenly lost normal power- steering assistance. The steering wheel became extremely difficult to turn and control while the vehicle was moving.I was able to call for assistance and when jumper cables were hooked on to battery underneath the vehicles hood the vehicle engine was able to restart, then was able to get the vehicle home without a collision or injury. The sudden loss of steering assistance created a serious safety risk to me, my children and others on the road. I photographed multiple warnings displayed on the dash panel, including Electric Parking break problem and collision mitigation system problem. This vehicle has a documented history of electrical/ mechanical concerns and prior repairs, including battery and alternator replacement. The exact cause of this most recent failure is currently UNKNOWN. American Honda motor co. has also opened a case #16640343 regarding this incident. I am reporting this to the federal safety agency due to the sudden loss of power- steering assistance occured while the vehicle was actively being driven and could have resulted in a collision.

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.

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.

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.

My 2021 Honda civic ex’ forward collision sensor light flashed mid intersection my brakes locked up causing me to be a victim of a hit and run. As I was in between policies with my insurance therefore I wasn’t covered for the accident and I am now suffering financial hardships.. dealership didn’t want to hear what I had to say because it was a new car & no recalls were announced at the time.

I have had a few incidents where I am driving and the brake signal starts flashing/dinging when I am nowhere near another car. In one instance; the car automatically braked in the middle of the highway with no car in front of me. This could have caused a major accident if I did not react quickly. In addition, I could have gotten major whiplash as I was driving over 40 MPH. I am also having issues with the auto lock feature on the car. Sometimes when I am driving the car will try to lock the doors even though the doors are already locked. It will continuously lock, the only way this issue has stopped is by turning off my auto lock function. I liked have the auto lock function on because it made me feel safe. There have been no warning lamps, messages or other symptoms prior to these incidences happening. I have not taken my car to the dealer or independent service center due to the cost of high cost the issue. I am open to someone coming to inspect the car as long as it is free of charge.

The coating on the wiring harness is soy based and rodents chew the wires causing multiple electronic failures. Power steering failed, Adaptive Cruise Control failed, Automatic Emergency Braking failed, Lane Keeping Assistance failed. Vehicle is extremely unsafe!
