Filed Nov 17, 2025 · Electrical, Engine · CA · crash

I became the 2nd owner of this car. My ownership had been a blessing because of the 1st owner having such a profound history of care and maintained. I randomly had a misfire in my cylinder 2. I took my car to EL Cerrito Honda in El Cerrito, Ca. After my car came from this dealership all kinds of different things begun to take place. Ive never put cameras or listening devices of any sort, nothing that was not made with my car should have been added or changed to its original make. The PCM/ECM was reset by the HDS system which has played a part in the illegal malfunctions of its systems. I have been robbed, Followed and watched from inside my car which i HAVE NEVER given anyone consent to have access to my private life. This has been 9 months of my car misfiring, Capital City Honda in Sacamento,Ca had done the same repair and did not sign the release of liability that El Cerrito Honda issued for the return of my 275.00$ diagnoses but the 571.00 paid for the work done they kept. The Bureau Of Automotive Repair told me to contact the federal safety agency for the complaint against Honda Motors for Laws/Regulations. My car has become a safety liability to myself and other drivers lives because of its mechanical and electrical altering without my consent and laws broken by the State of California Vehicle Codes and Pen code 637.7.

Car revs up at a stop sign, red light, heavy traffic, recently when making right turn. While in heavy traffic, stop and go barely moving, car stopped with foot on brake, traffic not moving, car revved up extremely high, the harder I stepped on the brake the higher it revved up, as cars started to move I took my foot off the brake, car jerked forward fast and I hit another car. No injuries, no major damage. Have taken car twice to mechanic, can’t find anything. Called Honda dealer same day of incident and brought in the car the following morning for diagnostic test, received phone call some hours later and told they can’t find anything wrong. There have been no warning lamps, and it happens unexpectedly. It’s happened before but very low and you can drive for months with nothing happening. I’ve been driving all year but this last time was different and happened 7/8 times. Found out on the internet there have been 10 recalls in 2019 one was for Accelerator Pedal May Bind/FMVSS 124, but I’ve never received notification on any of the 10 recalls.

Electrical component malfunctioning Knock Sensor: code error: p0325 I noticed my check engine light had came on but wasn't on for long and had turned off on the dash. A few weeks later the check engine light reappeared and did not go back off. Upon this happening I noticed a major difference in my vehicle performance. The fuel consumption had significantly increased, I recognized these shake like vibrations when sitting in park or at a complete stop. A "knocking noise" I would hear coming from the engine, as well as rough idling almost as if there was a "stalling/hesitant" idling that sounded very off. Adding a very noticeable reduced power from the engine that was not there when the check engine light was not on. This has been a confirmed malfunction and should be replaced due to the importance the knock sensor provides to the engine of this vehicle. This was confirmed by an employee at a parts store, with there computer code reader. Upon request for inspection; I have open availability. Confirmed: March 4, 2025 The additional code provided also stated the catalytic converter is recommended to be replaced as well. Engine related systems that power the vehicle such as (catalyst pipes) Powertrain (previously recalled prior time frame) due to this being a numerously reported issue with many other owners of this same vehicle I own. There is a reoccurring issue that absolutely goes hand in hand with the performance and job of the also stated ongoing problems I'm facing. The knock sensor is a vital part to the powertrain system that helps optimize engine performance and protects it from harmful knocking by monitoring combustion irregularities. Potentially if these are current issues, and have caused any kind of damage, the damage alone effects as follows: -wiring issues, internal malfunction, physical damage , corrosion from exposure to engine fluids, internal short circuit, mechanical damage, faulty wiring,excessive vibrations, wear and tear from use.

I just bought the car and had it 1 week and I was driving to work when the check engine light came on suddenly and car started misfiring. This happened right when I was stopped at a light and turned on my A/C. 3 codes came on which were p0420, p0139, and p2647. I was told I need to reprogram the powertrain control module. I have seen many recalls on here for that same thing but when I put my VIN number in it says 0 recalls for my car. I just really feel it is related to campaign 11v395000

Check engine light came on, car acts like it has no power on take off, shifting hard, once up to maybe 40 MPH car begins jerking and the A/C and heat stopped working correctly at almost the same time within a day or two. I can turn the air on and it will blow for maybe 20 seconds then just completely stop blowing which being it all happened at practically the same time is fishy to me. The car only has 156k miles and I can't afford to continue making payment and pay a couple thousand to get it fixed. This is crazy I thought honda was supposed to be a great car.
