I’m having two continuous, multiple incident, problems that the dealership swears up and down do not exist. I have tried calling the dealership multiple times, and the national Honda customer service line. Problem number one, sudden, breaking while driving at highway speed with no vehicle or other objects in front of me. Second problem is the adaptive cruise control no longer is activated on the vehicle after the most recent software update. Although Honda says they have not removed this component from my car or it’s software, the vehicle no longer slows down automatically when approaching a vehicle from behind while cruise control is activated

I experienced "rough running" of my 2013 Honda Insight just prior to August of 2021. Initial work on the vehicle helped, but repairs became increasingly expensive and extensive. EX: A simple oil change on about 8/2/2021 (mileage at 64,545). At about mileage 68,370 the vehicle failed again (showing check engine light / stalling); repair shop found a misfire on cylinder #4, and all 8 of the spark plugs were replaced. Â Then on/about Nov./2022 (mileage at 71,988), the vehicle was running rough again (with check engine light on) and the repair shop found a miss in cylinder #4 again, and then replaced cylinder #4 Â spark plugs and coils. On/about Feb./2023, the vehicle had more problems (running rough) and then the repair shop found a misfire on #4 again (spark plug was replaced.) On/about 5/18/2023, I took my vehicle in for a routine oil change. About two days later, on/about 5/20/2023, I (along with my girlfriend) drove on the freeway for a long trip. We had only been on the freeway for a few miles when the engine died. I had accelerated to 75 m.p.h. on a slight upgrade and was in the process of setting the cruise control when the engine revved up to 4,000 r.p.m.'s (as if it was climbing a steep hill); several warning lights showed up on the dashboard. Â I immediately disengaged the cruise control while in the left lane and (thankfully due to no vehicles being near us) was able to get the vehicle off to the right edge of the freeway. The vehicle had no power. I called a tow truck and the driver attempted to drive the Honda Insight onto his ramp (with thick smoke billowing out of the exhaust pipe) but it was only able to go half the car length up the ramp. At first, I was told it needed 2 spark plugs and was fixed. I reminded them that all 8 had recently been replaced; they then said no compression on #2 / that engine was dead. Took it to Honda; diagnosed it as the oil consumption issue. Check lights are for systems: emmission, brake, VSA, w/ various other lights on dash.

I previously reported this issue to the federal safety agency 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 to 30 mph in the driving lane. This sudden slow down exposed me to possible rear end collisions by following vehicles that were surprised by Insight's slowing in the driving lane. Once while driving at 70 mph in the passing lane with the ACC controlling the distance to the vehicle in front of me, the leading vehicle moved to the right lane, clearing the lane in front of me. When the Insight approached the vehicle that had moved to the driving lane and was then going at a slower speed, the Insight applied its brakes, quickly slowing the Insight to 40-50 mph. Again this sudden slowdown exposed me to a rear end collision by the vehicle behind me that was also going 70 mph. This is the same issue that I reported earlier. Despite the Honda dealer where I bought the vehicle servicing the ACC system under warranty, this unsafe issue still exists. It seems that the ACC is not "unlocking" from a leading vehicle when it moves to the right despite the path directly forward being clear. Please advise as to Honda's next step in resolving this safety issue. Thanks [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I started the car on December 9th to find a bunch of errors. All the sudden I have lost my cruise control, collision prevention assist, light assist, and other features. I immediately took the car to the nearest Honda dealership near my home and got it checked out. The code showed that part #36163-TXM-A45, a camera used for these features, had failed. I was told by Jessie Loso, the repair representative, that the part will need to be replaced. The car had only 14,763 miles on it however because it was barely driven during COVID lockdowns. Now the original part was not damaged and it had failed on its own for no apparent reason. The only reason that we were given by Victory repair department is that the car was left out in the elements. This was not an appropriate excuse for this failure considering we live in an area where many people park on the street or use their garages for storage, due too lack of space in their homes. I was told by Victory Honda in San Bruno. CA to call Honda about the defect in the part and for reimbursement. The complaint was placed with Sady Case #13552610 on December 22nd with Honda itself. I was told that since there was no recall on the part itself, that I would not be reimbursed and that I would not get an extension on my warranty. I asked to speak to a manager or supervisor because I was not even being heard out by the representative. I was informed that a manager would get back to me eventually, but I would still not be reimbursed for a part that had failed for no apparent reasons or damage. I am writing this report today because this part is tied into many safety functions of the car. If the part has malfunctioned in this way, then who is to say that the car won’t break randomly due to the same part. I find this extremely concerning and was told by BAR in California to report it to the federal safety agency just in case it is a consistent issue with Honda vehicles.

The recent the federal safety agency 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.

Both types of errors have occurred multiple times. Sometimes, the forward collision warning system triggers when no obstruction is present. More frequently, the adaptive cruise control decelerates even when no car is nearby or the car in front of me has not decelerated. In both cases, depressing the accelerator pedal overrides the automatic braking and avoid an accident.

I bought my new 2019 insight 4dr CVT touring jan 2019. After less then two years old 5 warning lights came on, acc-adaptive cruise control, lkas-lane keeping assist, collision mitigation braking system, road departure mitigation and auto high beam. I took it to my local honda dealer they found the code b2a60-49 - multipurpose camera unit internal electronic malfunction. Because the car had over 30,000 miles (outside there warranty) they told me to call honda america customer service and have them approve repairs. My call to honda america was a call from hell, rude and no help whatever, I asked a dozen times to please talk with a supervisor and the answer was no. I was then cut off. All the safety features the come with the car are not not working and honda will not fix it. For me to have it fixed will be over $1600 (see attachment)
