2016 Honda Accord Engine Problems

My Accord V6 suffered catastrophic engine failure due to a bent connecting rod/seized bearing while driving at highway speeds. This is the exact same failure described in Recall 23V-751 for other Honda V6 models.

Valve cover leaking at 35000 miles. Gasket faulty.

On several occasions, as I’ve traveled down the interstate, getting off of an exit the car engine completely shuts off and dies before coming to a complete stop

Rattles during cold start.

My 2016 Honda Accord has approximately 137,000 miles. I change the oil, filters, etc. at regular intervals. One night I noticed a ticking when going uphill. I thought it might be a belt.(no warning lights) The next day I had to go somewhere, and on my way back the ticking got noticeably worse and then the engine started screeching. Massive loss of power. Shortly after, a loud bang/thump noise and the car stopped running. I pulled into a school parking lot, got the car towed. Next day the mechanic where the car was towed said I threw a rod, and it went through the engine block and the oil pan; and my engine would have to be replaced. I have not (yet) replaced the engine (waiting for estimate). Spoke to Honda corporate (case #XXXX) to see if they could help me out (financially) with the replacement, because everyone I talked to said it's highly unusual for a Honda to throw a rod with mileage this low (anecdotal I know, but still). I spoke to local Honda dealer (Honda corporate said it would have to be inspected by Honda) but have not had it towed there yet.

The contact owns a 2016 Honda Accord. The contact stated while driving approximately 70 MPH, the vehicle lost automotive power. The vehicle failed to accelerate with the check engine warning light was flashing off and on. After turning off and restarting the vehicle the check engine warning light was flashing and remained with the traction control warning light was illuminated. The vehicle was later towed to the local dealer who diagnosed that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was contacted but no assistance was offered. The failure mileage was 80,000.

My 2016 Honda Accord with 2.4 engine failed due to rod bearing failing at 100K mileage. Knocking from engine bay is what brought my attention to it and from there i brought it into mechanic. I change oil religiously at 5K intervals. I own 4 different accords and never seen this happen before.

The contact owns a 2016 Honda Accord. The contact stated that while his friend was driving at an undisclosed speed, the vehicle inadvertently lost motive power. The driver was able to coast to the shoulder of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the engine connecting rod bearings, requiring that the engine be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 37,000.

The contact owns a 2016 Honda Accord. The contact stated after driving 35 MPH and arriving at her destination, the check engine warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The mechanic determined there was a failure with the rear main seal, causing fluid to slowly leak out from the rear main seal. The vehicle was then taken to a second independent mechanic who confirmed the diagnostic test result. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 93,500.

Engine harness, sensor and gasket needed to be replaced. FAULTY WIRING!!! Bulletin Honda initiated indicated to replace all parts. This is a defect on this vehicle that has been in a very dry climate and has been stored in a garage since purchase. The cost to repair was over $3,100. Honda knows about this issue and has has yet to recall the Accord Sedans for repair. I would like Honda to reimburse me for the cost to replace all parts and labor. This vehicle only has 59,576 miles on it and the original harness should have lasted the lifetime of the vehicle. This is a safety issue.

The car had a problem where it will not start because the stater grinds. Honda knows about the problem and won’t do a recall instead they charged me to have the remove the engine. Install a new torque converter and starter. They said the factory had a bad batch of torque converters. And quite a few cars were affected by this problem. Seems ridicules that a problem they k ow about with a part quality is the problem of the consumer. It’s about $3400 for each person that has to deal with this. The way the starter stays engaged and just grinds it could easily cause a fire.

Car burns 1 qt of oil every 3k miles. More oil needs to be added between regular service intervals or the engine will become damaged from lack of oil.

my 2016 Honda Accord EX-L V6 is on it's 4th starter.A service Bulletin has been issued 16-002 to fix the problem ,but it has not made a difference.I have contacted Honda Corp(Case 13172338) i August 2022 and they did not want to help even though they knew it was a on going problem with V6 owners.The internet has plenty of V6 owners that have the same problem and are left with cars that can't be fixed properly. I believe that since Honda does not have that engine since 2017 they are wishing the customers will just go away.

Burns oil. Have to add a quart every 1000 miles.

The contact owns a 2016 Honda Accord. The contact stated that while turning on the vehicle, the engine started but then turned off by itself however, the radio and AC remained on. The vehicle was not diagnosed nor repaired. The dealer and manufacturer were not made aware of the failure. The failure mileage was 75,000.

Engine ratlles for about 1-2 sec during cold startup. Car has 94000 miles.

I have a 2016 Honda Accord EX -L. V6 .it has 100500 miles .In that time it has gone through 3 starters.Honda has issued a service bulletin( 16-002) but never a recall.Checking the internet there a lot of people having the same problem.I have filed a complaint with Honda motor and they want to split the cost of repair. I don’t think that’s fair because it is a known problem because of a design flaw

I HAVE A TOURING TRIM OF THE HONDA ACCORD 2016, MEANING IT HAS A V6 ENGINE. AT AROUND 38,000 MILES, THE STARTER STARTED ACTING UP. WHEN I TRY TO START IT, IT MAKES A GRINDING NOISE AND WON'T START. I LIVED WITH IT FOR A LITTLE BIT BECAUSE I'M USUALLY ABLE TO GET IT TO START AFTER A COUPLE OF ATTEMPTS. I BOUGHT A BRAND NEW STARTER FROM HONDA, INSTALLED IT, AND THE CAR WORKED PERFECTLY AGAIN. IT STARTED EVERY TIME. 1 WEEK LATER AND THE ISSUE STARTED HAPPENING AGAIN. IT DOESN'T HAPPEN AS OFTEN, BUT IT SHOULDN'T BE HAPPENING AT ALL. IT'S A BRAND NEW STARTER AND I'M HAVING THE SAME EXACT ISSUE AS BEFORE. IT HAPPENS LIKE ONCE A DAY NOW. THE OLD STARTER WAS GIVING ME ISSUES EVERY OTHER TIME I TRIED TO START THE CAR. WON'T BE LONG BEFORE THE SAME HAPPENS WITH THIS BRAND NEW ONE.

TL* THE CONTACT OWNS A 2016 HONDA ACCORD. WHILE MERGING INTO TRAFFIC AT APPROXIMATELY 50 MPH, THE CONTACT CRASHED INTO THE REAR DRIVER SIDE OF ANOTHER VEHICLE. WITHIN SECONDS OF STOPPING, FLAMES EMITTED UNDER THE HOOD AND EVENTUALLY SPREAD THROUGHOUT THE WHOLE VEHICLE. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. A POLICE REPORT WAS FILED. NO INJURIES WERE SUSTAINED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 10,000. THE VIN WAS NOT AVAILABLE.

VOLATILE ORGANIC COMPOUNDS ,INCLUDING "METHYL ISOBUTYL KETONE" ARE ENTERING THE VEHICLE CABIN WHILE THE ENGINE IS ON. THIS IS CAUSING SERIOUS EYE IRRITATION AND BREATHING IRRITATION. THIS DESPITE THE AIR CONDITIONING BEING ON, ALL VENTS CLOSED, ALL WINDOWS UP. I'VE ATTACHED THE RESULTS OF A "PASSIVE DIFFUSE MONITOR" THAT WAS USED IN THE CABIN TO MONITOR THE AIR QUALITY FOR APPROXIMATELY ONE WEEK IN DECEMBER 2016.
