2020 Honda Accord Powertrain & Transmission Problems

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

Starting sconce July the car will vibrate at random times and will hesitate and buck while car will vibrate and not want to move have brought the car back to the dealership over 4 times now and they can not find any issues despite me having videos and any information I can gather since July if 2024

CVT belt prematurely broke causing transmission failure on 2020 honda accord. Car has 93000 mile.

The vehicle's transmission stalls when trying to accelerate, causing unnecessary RPM fluctuations. While going downhill with the brakes applied, the RPM gauge spikes pass 4000 RPM causing the car to accelerate rather than slow down. when this occurs, extra pressure has to be applied onto the breaks to slow vehicle down. If enough space isn't given to the car Infront, pressing the break will cause a crash. Accelerating too fast on the highway will cause blown head gasket if transmission is stalling. This seems like a common issue with 1.5L engine & Honda's CVT transmission as other owners has been through similar issue & proven by independent service center. I've taken the vehicle to different dealer for inspection. only recommendation is transmission fluid change. Dealers refuse to do anything regarding the actual issue at hand.

FROM OCT 10 TO OCT 14, I PARKED MY CAR AT OFF AIRPORT PARKING LOT FOR 5DAYS. WHEN I CAME BACK, MY CAR DIDN'T START. MY CAR WAS TOWED TO THE CLOSEST HONDA DEALERSHIP. I GOT THE INSPECTION REPORT FROM THE DEALERSHIP STATING THAT THE REASON WHY MY CAR DIDN'T START IS DUE TO BAD GAS. I WENT TO THE GAS STATION, WHERE I PUMPED MY GAS LAST TIME BEFORE I FLEW OUT OF ATL, TO CHECK WITH THEM. THEY PROVIDED ME A COPY OF THE SYSTEM STATUS REPORT OF 10/9/20 SHOWING THAT THERE WERE NO ISSUES. SO I WENT BACK TO THE DEALERSHIP AND THEY TOLD ME THEY HAVE CONFIRMED THAT #3 CYLINDER IS FULL OF WATER; THEY SAID THEY COULD GET A FUEL SAMPLE ONCE I AUTHORIZED THEM TO WORK ON THE FUEL TANK REMOVAL AND CLEANING. ONCE THEY PROCEEDED, THEY STATED THEY FOCUSED ON CLEANING THE SPARK PLUGS AND PERFORMING AN OIL CHANGE WHICH LED THEM TO FIND OUT THERE IS INTERNAL DAMAGE TO THE ENGINE. SO THEY TOLD ME THEY WOULD STOP UNTIL MY INSURANCE COMPANY CHECKS THE CAR. THEY SAID THEY TOOK MULTIPLE FUEL SAMPLES AND DID NOT SEE WATER BUT THERE WAS WATER FILLED IN THE ENGINE CYLINDERS. THEY HAVE ASKED ME IF THE CAR WAS IN A FLOOD, BUT THERE WAS NO MASSIVE RAIN OR STORM WHICH FLOODED THE AREA. THEY EMPHASIZED THAT IT IS NOT A WARRANTABLE REPAIR AS IT IS NOT A PROBLEM CAUSED BY THE MANUFACTURER, WHICH SOUNDED QUESTIONING. THE TECHNICIAN TOLD ME IF THERE IS NOTHING WRONG WITH THE OIL AND FUEL TANK, THEN THE ONLY WAY THAT WATER CAN GET INTO THE ENGINE IS MANUALLY POURING LOTS OF WATER THROUGH AIR INTAKE, WHICH ALSO SOUNDS RIDICULOUS AS I HAVE NEVER TOUCHED IT NOR THERE WAS NO TRACE OF SOMEONE TRYING TO OPEN MY HOOD FROM INSIDE AND PUTTING WATER. AFTER I EXPLAINED TO THEM, THEY SAID THEY STILL CANNOT PROVIDE AN ANSWER AS TO WHY THERE IS WATER, BUT IT CANNOT BE WARRANTABLE REPAIR. IF THEY DO NOT KNOW THE CLEAR CAUSE OF THE ISSUES, HOW CAN THEY STRONGLY CONFIRM IT IS NOT DUE TO MANUFACTURER ISSUES?

THE CAR WAS IN MOTION ON THE HIGHWAY WHEN ALL OF A SUDDEN THE CHECK ENGINE LIGHT CAME ON AND IT STOPPED ACCELERATING. I PULLED OVER AND COULD NOT GET THE CAR TO ACCELERATE MORE THAN A COUPLE MPH.

WE RECENTLY PURCHASED A 2020 HONDA ACCORD EX. WE HAVE DRIVEN IT ABOUT 3200 MILES IN THE 3 MONTHS WE OWNED IT. DURING THAT TIME IT HAS SHIFTED FROM DRIVE TO NEUTRAL 3 TIMES WHEN MY WIFE, WHILE DRIVING FORWARD AT NORMAL SPEEDS, LIGHTLY BRUSHED THE SHIFTER WHILE ADJUSTING A CONTROL ON THE DASH OR ON THE STEERING WHEEL. THE THIRD TIME SHE ATTEMPTED TO QUICKLY SHIFT BACK TO DRIVE AND BECAUSE THE LOCK IS ON THE FRONT SIDE OF THE SHIFT KNOB IT WAS DEPRESSED AND SHE WENT PAST DRIVE INTO SUPER (LOW GEAR); THE LOWER GEAR SLOWED THE CAR VERY ABRUPTLY (AND, OF COURSE DID SO WITHOUT ACTIVATING THE BRAKE LIGHTS) AND SHE WAS NEARLY REAR ENDED. THIS IS A VERY DANGEROUS SITUATION AND WE ARE CONSIDERING SELLING THE VEHICLE.
