2021 Honda Insight owner complaints

I received a 2021 Insight Seat Weight Sensor Safety Recall in September 2025 saying that recall replacement parts were now available at Honda Dealers. Ever since I received this notice, none of the Atlanta area Honda dealers are able to remedy the defect in my vehicle due to lack of parts, contrary to the notice saying parts are available.

Several times since purchasing this vehicle the blindspot warning has lighted when no vehicles are present. It has lighted while driving next to the k rail center barrier, driving in the middle lane of a 3 lane highway, also at night when no cars are around on a 2 lane road. It has also lighted while driving in the rain with no vehicles around.

Honda has a feature called "Traffic Sign Recognition System". With its mounted cameras the car is able to capture traffic signs while driving and display them on the dashboard. THE PROBLEM: the system is not very good at reading traffic signs and posts incorrect speed limits at times. I tried to turn this feature off but Honda does not have an option for that. Displaying the incorrect speed limit is a huge liability for the owner of the car if they decide to lend it to a friend or rent it out.

This has been happening with my two honda cads. I currently have Honda 2023 CRV and 2021 Honda Insight. the Collison Mitigation Braking System brakes really hard for no reason

I am urging your immediate attention to a safety issue affecting the 2021 Honda Insight. The vehicle’s infotainment system, which controls key safety features including the Tire Pressure Monitoring System (TPMS), has failed. This malfunction prevents drivers from monitoring tire pressures, applying necessary software updates, and accessing navigation and hands-free features, which significantly increases the risk of accidents. The system's failure distracts drivers and compromises critical vehicle safety functions, warranting an urgent recall investigation. Thank you for your attention to this critical matter.

On two (2) occasions, the "collision mitigation braking system" braked with no reason. It has happened on a quiet and straight line residential street with no other moving vehicle, pedestrian, animal, or any other obstruction in view. After one second or so of braking, it returned to normal. It is available for inspection. I have not spoken to the local Honda dealer about it, and there were no adverser repercussions. There were no prior warnings of any system malfunction.

The recent NHTSA disclosure of issues with Honda's driver-assistance technologies causes me to write about the troubling performance of adaptive cruise control on my 2021 Insight. When following another vehicle on controlled access highways, the system works fine. However if the vehicle in front enters an exit lane and slows, my car is slowed to the point that the brakes are fully applied, causing vehicles behind me slam on their brakes or swerve to avoid rear-ending me. The ACC does not "let go" of the car in front of me.

Car emergency braking system engaged while there was nothing in front of the car. The automatic brakes were applied and the brake indicator flashed on the driver screen with no warning.

I have had 6 times where the collision warning has slammed on the brakes when there is no vehicles on the road in front of me. This is very dangerous when vehicles are behind you. I'm afraid that this car is going to cause a reck and get me and my wife hurt. A device that is supposed to help you has the ability to get you hurt. The dealer said that they were unable to get it to do it, and that if I was afraid of it that I could turn it off. Dosen't that defeat the purpose of getting it in the first place. I think Honda is just trying to sweep it under the table. Who knows how many other vehicles they have out there with this problem.

I previously reported this issue to NHTSA and was given the case number [XXX]. Here is my recent letter to Honda. RE: Case #[XXX] (I was informed that this case was closed) Although I did not agree that the adaptive cruise control issue was resolved, Honda closed the referenced case. I am writing to confirm that the issue is not resolved. I rarely drive the Insight but did so yesterday on a two lanes in each direction, limited access highway. Here are my experiences: On multiple occasions while driving at 60 mph in the right hand lane with ACC controlling the distance to the vehicle in front of me, the vehicle in front moved to the exit lane clearing the path in front of me. As the exiting vehicle slowed in the exit lane, the ACC applied the Insight's brakes, quickly reducing my speed t

I received the "important safety recall" letter in March 2024 from the Honda Automobile Division regarding the seat weight sensor circuit board. The letter said that in a crash, the airbags could deploy in a dangerous fashion. I have called my Honda dealer three times since that date. Today, Sept. 10, 2024, I was told again that the dealer did not have the parts to perform the repair, and that it had no idea when it would receive them. I called the national Honda number. Same answer. I called 888-327-4236 to see if NHTSA had more information, held on the phone, then provided my number for a call back. When the NHTSA returned the call, the line was choppy. Either the call dropped, or she hung up on me. She did not call back. I have waited patiently for five months. Neither NHTSA nor my l

The contact owns a 2021 Honda Insight. The contact stated while driving at 55 mph, a deer jumped in front of the vehicle causing the contact to hit the deer but none of the air bags deployed. The contact mentioned that the automatic brakes were engaged during the incident. No one was injured and a police report was filed. The contact stated no warning lights were illuminated. The vehicle was towed to a dealer and was awaiting an inspection. The manufacturer was not informed of the failure. The failure mileage was approximately 6,500.

The contact's daughter owns a 2021 Honda Insight. The contact stated that while her daughter was driving at an undisclosed speed, the front driver's and passenger-side air bags suddenly deployed without impact. There was no warning light illuminated. The contact stated that the air bags cracked the front windshield and injured the driver's arm. The police arrived at the scene, but no police report was filed. The contact was unsure whether the driver had received medical attention. The contact's daughter had someone drive the vehicle to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.

While my wife was driving my car on a busy road. The servo brake control unit/ pedal simulator broke making it near impossible to stop the car. She had to crash the car into a parking block. And Honda import/export is uncooperative and dismissive of the fact that my wife and daughters lives were jeopardized due to the part malfunctioning

Summary American Honda Motor Co., Inc. (Honda) is recalling certain 2021 model year Insight vehicles. A capacitor in the printed circuit board of the front passenger seat weight sensor may crack and lead to an internal short circuit from the exposure to environmental humidity. Safety Risk In the event of a crash, the front passenger frontal and knee airbags may deploy despite the presence of an infant in a child seat or child, increasing the risk of injury. I have reached out to the dealership and said that they are waiting for the parts from the manufacturer. It has been 4 months and have not heard back from the dealership nor from the manufacturer. The safety risk states in the event of a crash, the front passenger frontal and knee airbags may deploy despite the presence of an infant

driver side headlight failed. available for inspection upon request. can't drive without headlight on at nighttime or dark days. I haven't gone to dealer yet. not inspected by manufacturer yet. warning and message: headlight system problem. headlight performance may be reduced. see your dealer. First appeared on 12/12/22. and I was told by gateguard that my left headlight went out, complete off. there was no incident, I didn't even know that it was completely off.

Under certain circumstances, the portion of the PCU that controls charging of the 12 volt accessory battery malfunctions, sending the PCU into a "fail safe" mode, preventing battery charging and activating warning displays for the driver. This has caused my vehicle to stall while driving, potentially increasing the risk of a crash. Other honda hybrids during this year have been recalled but not by my VIN number, however I am having the exact same issue. Below has me give a specific date but this happens almost every morning.

The brake servo control unit feel simulator which reduces the simulation force provided to the brake pedal during emergency or failed conditions and is a key component of realizing a Regenerative Braking System. It provides a good pedal feeling to a driver, improves energy recovery and ensures braking security. My safety has been put at risk as that part is integral to my brake system (including the hybrid function) e.g. my car was in reverse and the brakes were not responding and had to leave my car. I towed my car to a local independent service provider and they confirmed via the OBD-II scanner that confirmed my break servo control feel simulator is bad and would need to be replaced. After doing research, the brake servo part is made in Japan by a company called Nissin. The part has been

There is a massive hood flutter when large vehicle drive towards me going above 50mph. It feels and looks like the hood is not latched correctly and going to open into my windshield. This has happened since I purchase the vehicle new in 2021

We purchased the vehicle on 1/23/21. On 2/4/21, I was driving in dobson, nc, when the power control unit (pcu) malfunctioned, leading to loss of power steering and brakes. When I started the car, the warning lights came on. I turned the car off and then restarted it without warning lights. I then backed out of the drive and started on my way. As I was descending a hill, the transmission shut off. I was able to coast to a stop with some braking. The car was towed to flow Honda in winston-salem, nc, where they replaced the pcu. We picked up the car on 2/9/21. My wife was able to drive it from winston-salem to durham, nc without incident. She then drove on I-40 towards our home in raleigh, nc. While traveling on I-40 at 65 MPH, the pcu malfunctioned again, and the transmission stopped working
