2019 Honda Accord Speed Control & Cruise Problems

The contact owns a 2019 Honda Accord. The contact stated that while at the stop sign to access the feeder road, while accelerating, the lights started flashing on the instrument cluster. The vehicle failed to accelerate above 5 MPH. The driver turned on the hazard lights, made a U-turn, and pulled over a block away at a stadium. The vehicle was turned off. The contact retrieved DTC: P0301, P0302, P0304, and P0300. A code reader was used to erase the codes. The vehicle was restarted and driven as designed. While the contact’s wife was driving, the vehicle failed to exceed 5 MPH. The vehicle was taken to the dealer for a routine recall repair on the fuel pump and software. The dealer informed the contact that the failure was not related to a recall. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 85,000.

In the past 2 months my car starting having rough idle issues. As recommended by the dealership, I replaced the head gasket as they said it was leaking coolant into the cylinder causing the rough idle. Almost immediately after paying for this, the dashboard lit up like a Christmas tree with multiple warnings and the car went into limp mode, lost acceleration and would have been extremely dangerous had we been on the interstate or multi lane road. Took it back to the dealership, ran another diagnostic and determined the fuel injectors needed to be replaced. These repairs cost over $5,000. Recalls have already been put in place for models around this one and Honda should acknowledge these problems as it is wide spread.

I have taken my car to the Honda dealership on multiple occasions because my car has stopped accelerating while driving on the interstate. The car will flash the check engine light and completely stop accelerating while driving. I was first told it was the fuel pump that was recalled and waiting over a year on the recalled part and multiple times breaking down while driving they finally replaced the part. After the dealership replaced fuel pump I continued to have problems unfortunately happening more often and worse than before replacing the fuel pump. I was then told my car was misfiring and needing a tune up which would involve replacing all four coil packs and spark plugs. I replaced all of these recommended parts with no resolution to my problem. I have since be told by the dealership my car needs all four fuel injectors replaced after running the diagnostic tests. After doing research it seems to be a common problem with this make and model car. I can’t believe with as many cars with this same issue and the safety issues with completely stalling in the middle of traffic there are no recalls on these cars.

ON THREE OCCAISIONS, THE DRIVER SAFETY ASSIST SYSTEM SHUT OFF. EACH TIME THERE WERE NO OBSTRUCTION IN RADAR AND THE DAY WAS NOT A HOT DAY. THE AUTO ASSIT CRUISE CONTROL SHUT DOWN TO. SHUTTING THE CAR OFF SEEMED TO RESET. I WAS UNAWARE BY PRESSING THE MAIN SWITH ON STEERING WHEEL WILL RESET THE SYSTEM. BUT AS I SAID TURNING OFF THE VEHILCE SEEMS TO RESET. I CHECKED LANE DEPARTURE BUT IT AFFECTED ALL SAFE DRIVING SYSTEMS. YOUR SYSTEM WOULD ONLY ALLOW ME TO CHECK ONE BOX IT WOULD NOT LET ME CHECK.

I received a letter in the mail stating that my fuel injections had a recall. 2024 Feb-Mar. Letter stated that I would not be able to get it fit until the fall because Honda Parts were backed up. At about May all my dash board lights were on, check engine, TPS, tire pressure. I assumed it was from the recall. At that time I had about 120,000 or 130,000 on my car, I'll have to check my oil change reports. Nov 2024 I was finally about to get my fuel injection fix, per the dealership. Lights were still on afterwards. Now February 2025, I get it check out, I need a new Turbo and an Engine because my gasket has blown. About December of 2024 I noticed I had issues with accelerating. My car jerks causing me some safety issues. This is my only car. I am afraid to drive it.

The contact’s mother owns a 2019 Honda Accord. The contact stated on multiple occasions while the accelerator pedal was depressed, the vehicle jolted back and forth. The check engine warning light also illuminated while accelerating. The vehicle was taken to an independent mechanic where it was diagnosed that the brake booster assembly needed to be replaced. The vehicle was not repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 55,000.

For more than the past two years I have been experiencing unexpected braking while driving my 19 Accord. There have been probably 20-30 random incidents....generally when I am changing lanes..I think? The braking lasts for 2-3 seconds and then all returns to normal. This has happened when other cars are near and when there is no other car ahead or behind. On at least a couple occasions I received a nasty horn from the car behind me due to my unexpected braking and more than once an uncomplimentary comment from my wife about my driving skill. Several times I feared being rear ended. I explained this braking action as my failure to use the turn signal when changing lanes. Upon reconsidering and after reading the recent NHTSA alert, this is a sensor/software problem in the ESC/Emergency Braking system. Please give this issue your prompt attention. I am the retired engineering manager of the braking system subsidiary of HONDA MOTORS.

NOT ONLY DOES THE INFOTAINMENT SCREEN SOMETIMES BLACK OUT WHEN I AM NAVIGATING, BUT THE EMERGENCY BRAKING SOMETIMES KICKS IN ON THE INTERSTATE HIGHWAY WHEN THERE IS NO CAR IN FRONT OF ME OR NONE ON EITHER SIDE. I ALSO GET OCCASIONAL COFFEE CUP ICONS WITH A DRIVER ALERT SIGNAL EVEN WHEN I AM DRIVING IN A STRAIGHT LINE, YET CONSCIOUS OF THE NEED TO STEER A BIT TO TELL THE SYSTEM I AM ALERT. THE ALERTS HAPPEN AT HIGHWAY SPEEDS. THIS HAS HAPPENED QUITE A FEW TIMES. THE DEALER'S ONLY RESPONSE WAS THAT HONDA IS AWARE AND BLAMES THE PROBLEM ON USING THE CORD THAT MUST BE USED TO ACTIVATE CARPLAY AND THE NAVIGATION SYSTEM!

WHILE DRIVING A NEW 2019 HONDA ACCORD SPORT WITH ACTIVE CRUISE CONTROL (ACC) AND LANE ASSIST AT NIGHT, THE CAR HAS ON THREE SEPARATE OCCASIONS OVER 10 MONTHS MALFUNCTIONED. BOTH THE ACC AND LANE ASSIST STOPPED WORKING. THE DASH SAID "COLLISION MITIGATION BRAKING SYSTEM PROBLEM" AND "ROAD DEPARTURE MITIGATION SYSTEM PROBLEM". IF THE CAR IS RESTARTED THE MALFUNCTION AND WARNING MESSAGES CLEAR. THE DEALER HAS LOOKED AT THE CAR THREE TIMES, BUT THEY HAVE NOT BEEN ABLE TO IDENTIFY THE PROBLEM.

COLLISION MITIGATION SYSTEM PROBLEM FOR ABOUT 45 MILES IN USE

DRIVING IN INCLEMENT WEATHER SNOW/FREEZING RAIN. THE HONDA SENSE RADAR WILL BECOME COVERED IN SNOW AND OR ICE CAUSING IT TO LIGHT UP THE DASHBOARD WITH WARNING LIGHTS. NONE OF THE HONDA SAFETY FEATURES WORK (ADAPTIVE CRUISE, LANE ASSIST, AUTOMATIC BRAKING) EVEN IF YOU ARE NOT USING THEM AT THE TIME THEY ALL SHUT DOWN. THE WORST BEING THE AUTOMATIC BRAKING COULD CAUSE WRECKS IF IT HASN'T ALREADY. WHEN THE DASH LIGHTS UP IT STARTS BEEPING CONSTANTLY AND YOU HAVE TO CLOSE OUT 3-4 NOTIFICATIONS BEFORE IT WILL STOP BLINKING. HAS HAPPENED ON HIGHWAY AS WELL AS JUST NORMAL DRIVING STATE ROADS. HAS HAPPENED TO ME 3 DIFFERENT TIMES. CAR HAS 12000 MILES

1ST TIME: ADAPTIVE CRUISE CONTROL ON, VEHICLE DRIVING UNDER 25MPH IN TRAFFIC. THE SYSTEM WORKS FINE UNDER A TIME LAPSE OF 1-2 MINUTES AFTER THAT THE SYSTEM TURNS OFF AUTOMATICALLY & WARNING INDICATION POPS UP ON DASH. "COLLISION MITIGATION BRAKING SYSTEM PROBLEM SEE YOUR DEALER" NORMAL CONDITIONS ON THE ROAD & TRAFFIC WHEN THE PROBLEM HAPPENS. THE WARNING LIGHT RESETS AFTER THE CAR IS TURNED OFF. TOOK THE CAR TO THE DEALER & NOTHING WAS FOUND IN THE SYSTEM. THEY RECOMMENDED REMOVING TOLL STICKER FROM THE WINDSHIELD. I REMOVED THE STICKER & LEAVE THE DEALER TO TEST THE SYSTEM. 2ND TIME: ADAPTIVE CRUISE CONTROL ON, SPEED SET TO 60MPH ON HIGHWAY. NORMAL CONDITIONS ON THE ROAD & TRAFFIC. SAME PROBLEM, THE SYSTEM WORKS FINE UNDER A TIME LAPSE OF 1-2 MINUTES AFTER THAT THE SYSTEM TURNS OFF AUTOMATICALLY & WARNING INDICATION POPS UP ON DASH.

WE BOUGHT A BRAND NEW HONDA ACCORD 2019(LX) ON JUNE 29, 2019. NOT EVEN A MONTH LATER I.E. ON SATURDAY, JULY 27, 2019 AT 7:49 PM MY HONDA ACCORD STOPPED IN THE MIDDLE OF THE HIGHWAY DUE TO UNKNOWN REASON. BEHIND US WAS A TRUCK AND WE WERE AT 70 MPH HIGHWAY, WE WERE ABOUT TO BE HIT EITHER BY THE TRUCK OR BY THE CAR ON THE RIGHT LANE. THANKS TO THE TRUCK DRIVER AND THE PERSON DRIVING THAT SUV WHO STOPPED IN TIME. WE MERELY ESCAPED DEATH LIKE SITUATION. POST THAT I CALLED HONDA ROAD SIDE ASSISTANCE AND THEY ASKED ME TO MOVE TO A SAFE LOCATION AND CALL THEM AGAIN. I TRIED TO DRIVE THE CAR AGAIN AND DROVE COUPLE OF MILES WHERE MY CAR FINALLY STOPPED MOVING AND SMOKE STARTED COMING FROM THE EXHAUST. SCARED WE QUICKLY EVACUATED THE CAR AND MOVED TO A SAFE LOCATION AT 8:23 PM. POST THAT COPS CAME TO ASK WHY WE STOPPED THERE, WE EXPLAINED THEM THE SITUATION. WE WERE TOLD TO STOP THE ENGINE AND WAIT THERE TILL THE TOWING CAR ARRIVED. I HAD SO MUCH TRUST IN HONDA AND WE ARE SO TRAUMATIZED WITH THIS SITUATION AND I STILL CAN'T BELIEVE HOW THIS HAPPENED. THIS IS A BRAND NEW CAR WITH TOTAL MILES OF 657 MILES. I DIDN'T EXPECT THIS FROM A BRAND-NEW CAR. WE WERE LUCKY ENOUGH TO ESCAPE DEATH ON THE HIGHWAY. WE WERE EXHAUSTED AND TERRIFIED WITH THIS EVENT. YESTERDAY HONDA SERVICE CENTER COMPANY CALLED AND TOLD THAT THE THE TURBO CHARGER FAILED INTERNALLY, CAUSING OIL TO GO INTO THE EXHAUST SYSTEM. THIS CAUSED CONTAMINATION OF THE CATALYTIC CONVERTER AND DAMAGED THE OXYGEN SENSORS. I AM NOT SURE IF I CAN OR ANYONE CAN TRUST HONDA EVER AGAIN. IF SOMETHING WOULD HAVE HAPPENED TO ME OR MY FAMILY WILL HONDA BE RESPONSIBLE FOR THIS. QUESTION IS DO YOU STILL TRUST HONDA ?

LEASED THIS CAR BRAND NEW 2 WEEKS AGO. TIRE PRESSURE MONITORING SYSTEM LIGHT HAS ALREADY CAME ON TWICE. CHECK AIR PRESSURE, IT WAS WHERE IT SHOULD'VE BEEN. LIGHT WENT AWAY AFTER I RESET THE SYSTEM. UPON DRIVING ON THE HIGHWAY USING ADAPTIVE CRUISE CONTROL AND LANE KEEP ASSIST, THE 'COLLISION MITIGATION: BRAKING SYSTEM PROBLEM. SEE YOUR DEALER' MESSAGE POPPED UP. HONDA SENSING FUNCTIONS WERE ALL DISABLED AS WELL AS REGULAR CRUISE CONTROL. THIS HAPPENED ON A CLOUDY EVENING AS THE SUN WAS SETTING. NO RAIN OR INCLEMENT WEATHER. MESSAGE WENT AWAY ONLY AFTER PARKING THE CAR, TURNING IT OFF AND RESTARTING IT. TOOK THE CAR TO THE DEALERSHIP TO HAVE IT INSPECTED BUT THE DIAGNOSTICS TEST CAME BACK INCONCLUSIVE AS THE COMPUTER WAS UNABLE TO DETECT ANY CODES. SERVICE GUY SAID THAT IT COULD'VE JUST BEEN A PLASTIC BAG OR FLYING OBJECT THAT HIT THE SENSOR OF THE CAR CAUSING THE MESSAGE TO POP UP.

I STARTED TO NOTICE MONTHS AGO, WHEN STOPPED OR IDLING, MY VEHICLE BEGINS TO MISFIRE OR THE RPM ACCELERATES.TOOK IT IN THE DEALERSHIP MULTIPLE TIMES, THEY CAN'T SEEM TO DIAGNOSE THE ISSUE. THIS IS A MAJOR SAFETY ISSUE, I HAVE ALMOST HIT SEVERAL PEDESTRIANS AND OTHER VEHICLES DUE TO THIS ISSUE.

ON APRIL 13, 2019, MY BRAND NEW, 2019 HONDA ACCORD SPORT 2.0T ON THE HIGHWAY GOING 55 MPH, WITH MERE/MILD RAIN BROUGHT AN ALERT OF COLLISION MITIGATION WARNING ONTO THE DASH. THE CAR HAS SINCE ALERTED ME OF THE SAME PROBLEM ABOUT 5 TIMES, IN BOTH WET AND DRY HIGHWAY CONDITIONS. WHEN TAKEN TO THE DEALER, THEY SAID THE CAR HAD NO RECORDS OF THE ALERT. NOT KNOWING IF THE HONDA SENSING SYSTEM WILL WORK IS VERY ALARMING AND I HAVE BECOME SCARED TO DRIVE THE VEHICLE AS I CAN NOT TRUST THAT THE VEHICLE WILL PERFORM AS ADVERTISED. I AM PAYING FOR A SERVICE THAT IS NOT SAFE TO USE OR NOT SAFE FOR OTHER MOTORISTS AS MANY OTHER ACCORD AND HONDA OWNERS HAVE REPORTED THE SAME ON THEIR CARS.

THE COLLISION MITIGATION BRAKING SYSTEM AND CRUISE CONTROL RANDOMLY STOP WORKING. IT REQUIRES A RESTART TO ACTIVATE THESE IMPORTANT SAFETY FEATURES. THE CAR WAS ON THE HIGHWAY EACH TIME. IT HAS HAPPENED THREE TIMES IN THE LAST WEEK. ATTACHED IS A PICTURE OF THE WARNING OF THE FAILURE.
