What component or system failed or malfunctioned, and is it available for inspection upon request? The turbo charger and the fuel pump How was your safety or the safety of others put at risk? Both instances I was driving and car automatically started to decelerate while I was on the busy interstate. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes by a dealer Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No but Honda has been notified because there is currently a recall out for these issues that includes my year of vehicle but not my vin. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes every system in the vehicle stated it was failing and engine light came on.

2020 Honda Accord Sport 1.5. Routine maintenance always done on time. At 108K turn my car on after a routine 45 minute drive an hour or so previous and all warning lights come on. TPMS, Brake System Problem, road dept system, emissions system. Dealer reports Head Gasket needs replaced and 3rd cylinder misfire, coolant leak etc. Quoted $5K to repair. Only 108K miles. Honda isn’t what it used to be. Quick search reveals the 10th Gen accords and civics suffer from early failure of this product routinely. Surely a known defect worthy of recall.

Was operating the vehicle at about 30mph and the braking system started malfunctioning by giving me limited braking power and throwing a bunch of lights on the dash along with sudden loss of acceleration. Tried to press the pedal again and it didn’t respond I drifted to a stop in the middle a lane in the road. Had to shut vehicle off then restart to regain function. All conditions were clear outside. The dealer I bought it from has been very suspicious since the purchase. Bought as a “certified pre-owned” but have had nothing but problems in the couple weeks of owning. Such as the TPMS system continuously going off saying “low tire pressure” the dealer has seen it multiple times and still can’t figure out the problem. They said they’re gonna start “throwing random parts at it” Issues just continue to get worse with little to no cooperation with the dealership. Will be inspected in the morning once it’s towed in. No longer feel safe operating vehicle. Warning lamps came on after the malfunction. Then flickered on and off a few times then stayed on when I restarted the vehicle.

Complete loss of power on acceleration. Car goes limp while driving on highway or a 50 mph street - very dangerous to have loss of power when other cars are driving fast too. We have replaced the spark plugs, coils, and fuel injectors. That was a waste of time and money bc the same problem existing- loss of power again! Turns out, it’s bc the Head gasket has a design flaw - deep grooves between the cylinder heads and head bolts that are not strong or tight enough. I have lost all trust for Honda bc this has not been issued as a recall. After quick online research- Everyone is having the same issue who has these models, this needs to be a safety recall bc Honda created a faulty head gasket design. This car is not safe bc the head gasket design, and I’m making payments on a car that I can’t even drive. Unethical for Honda to not take accountability for this! I’m driving my 03 Toyota that has over 300k miles is more reliable than this 2020 Honda - paying for a car I can’t drive makes me despise Honda for not issuing this recall.

While driving my 2020 Honda Accord Hybrid, VIN [XXX] , the car would start exhibiting rough engine feels, and all of the dashboard lights would come on. The car would lose power at highway speeds, and I’d have to pull over to turn the car off and on. When checking on OBDII meter, getting P0301 codes. I have replaced the coils and plugs twice and still not better. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on I70 mm152.2 my transmission went out and I was left quickly slowing on the interstate. I was in left line and cars were passing on the right. I needed to get over because I could not pull over to the left. Thought I might get stuck stopped on the interstate but was able to get over safely. Car only had 88000 miles on it and was less than 5 years old
