2016 Honda Odyssey Power Train

Spark plug fouling, Piston seal leak on 60,000 miles car

Vehicle shudders on acceleration

The transmission shifts hard in first and second gear, It happens at different time sometimes when it is cold and a lot of times when it is at driving temp. Yes it is available for inspection upon request. This has been happening for over a year. We could be rear ended because it happens after a stop at a red light or stop sign, which could cause someone to hit me in the rear and could injure both us and them. It bucks so bad that it hurts me as a driver and my passengers. There is a class action law suit in California for this problem. No warning lamps or messages or other symptoms of problem prior to the failure. It just happens and every service center says it just happens which is not right.

At highway speeds (50-65mph), the transmission would jutter/shudder when trying to either accelerate or decelerate from constant speed. The issue incrementally got worse and got to the point where the van was undrivable on the highway. I found the service bulletin 14-043 and brought the van into my Honda Dealer with a copy of the service bulletin. They test drove my vehicle and agreed this was the issue. The software was updated and ATF was flushed at no cost.

While accelerating, especially up an incline, the vehicle (2016 Honda Odyssey) shudders as if the transmission is repeatedly slipping. Instead of rising smoothly, the tachometer bounces up and down as it is increasing. If you plotted the rpms as a function of time, it would look something like a "sawtooth" pattern. The issue seems to go away once a cruising speed is reached. This jerking makes me worried that the transmission could fail at any time and result in an emergency situation and/or accident. The vehicle is currently at the dealership but they seem uncertain as to what will fix the issue. They want to start with a $600 transmission flush. Then if that doesn't fix it, they want an additional transmission flush. And if that still doesn't fix the issue, then they want to try replacing the torque converter. This appears to be an issue known to Honda but of which owners have not been made aware. It appears to be a flaw in Honda's software resulting in an inability to maintain the transmission fluid in an safe and appropriate range. Honda should be required to notify all owners and issue a recall to fix this issue.

2016 Honda Odyssey developed torque converter judder as shown in Honda TSB 17-043 dated 2/27/2018. This lead to problems accelerating and maintaining speed which is a safety issue. No warning lamps or messages appeared. The problem was confirmed by a local transmission repair service. We are awaiting warranty information for the repair as there has been no campaign or recall for this well known issue.

Van is stuttering at a low rate of speed 25 mph. Car shakes and rattles. Disappears with higher acceleration. Took it to local car repair shop who suggested Honda as it should be under warranty or recall. Spoke with Honda dealer who states no recall, but there was a TSB 17-044 service bulletin extending the warranty to 8 years or 80,000 miles whichever comes first. We were never notified of this extension and are now at 82,000 miles. Honda Customer Care said there is nothing they can do, but will assign a case manager who should contact us in a week. In the meantime I am adding more miles to the car.

The torque converter is failing. When accelerating, the van will shudder and shake, usually between 25-30 mph and sometimes at 45mph. My vehicle is available for inspection. When merging onto the highway, this problem occurred, slowing my acceration which almost caused me to be hit from behind. I reported the problem to Honda. They are aware of the problem. Said I needed to bring my van in to have conputer reflashed and transmission flushed three times. The price to have complete is $481. I have 64k miles on my vehicle. Honda's warranty was to 50k, and there are no recalls. No warning lights or messages came on prior to this happening. It began around 60k miles.

Problems accelerating, the transmission slipping while accelerating. Possible torque converter locking up. Taking to dealer soon. No warning lamps, messages yet.

The transmission keeps slipping between 20 to 65 mph. The Dealer (Price Honda - Dover, DE) flushed the ATF system like the Service Bulletin 17-043 & 17-044. The issue still keeps happening. They said the Torque converted needs to be replaced but it is national backorder. But since it is on backorder, They can not do anything about it. They are saying the car is safe to drive and that driving it will not cause damage the transmission. This seems very unlikely.

TRANSMISSION KEEPS SLIPPING. NOT TYPICAL FOR A CAR SO NEW. EVERYTIME WE ACCELERATE, IT SLIPS.

AFTER PUCHASING MY CAR, THE TRANSMISSION STARTED SLIPPING ON A REGULAR BASIS. BETWEEN 5-40 MPH IT'S LIKE THE CAR DOESN'T KNOW HOW TO SHIFT GEARS AUTOMATICALLY AND JOLTS EVERY ADDITIONAL 5MPH OR SO. SEEMS VERY UNSTABLE. IT HAS BEEN A PROBLEM SINCE ABOUT 28K MILES. WE'RE AT 51K AND IT STILL DOES IT EVERY TIME WE DRIVE. THERE ARE NO DIAGNOSTIC CODES THAT SHOW UP (WE WENT TO SEVERAL DIFFERENT REPAIR PLACES) AND ARE TOLD IT'S IMPOSSIBLE TO DO ANYTHING ABOUT OTHER THAN REBUILD THE TRANSMISSION. THIS IS ABSOLUTELY NOT WHAT SHOULD HAPPEN ON A CAR AT LESS THAN 30K MILES.

TL* THE CONTACT OWNS A 2016 HONDA ODYSSEY. THE CONTACT STATED THAT WHILE COMING TO A STOP AT A STOP SIGN, THE ENGINE REVVED UP DESPITE THE CONTACT'S FOOT BEING ON THE BRAKE PEDAL. THE CONTACT HAD TO PLACE THE VEHICLE INTO PARK AND TURNED OFF THE VEHICLE. THE CONTACT TOOK THE VEHICLE TO GERALD JONES HONDA LOCATED AT (4022 WASHINGTON RD MARTINEZ GA 30907, (706)228-7000). THE MECHANIC WAS UNABLE TO DIAGNOSE OR PROVIDE THE CAUSE OF THE FAILURE. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC ON 3-11-20 WHO STATED THAT THE FAILURE MAY BE DUE TO A DEFECTIVE TRANSMISSION SENSOR. THE ECU WAS REPROGRAMMED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 200. *LN*JB

STARTED WITH TRANSMISSION JUDDERING AT 45,000 MILES. TOOK IT IN FOR A FIX AND IT GOT FLUSHED AND REPROGRAMMED UNDER WARRANTY. NOW AT 77,000 IT SLIPS IN AND OUT OF GEAR WITH A BANG AND A BIG JOLT. I WAS DRIVING AT A LOW RATE OF SPEED IN MY NEIGHBORHOOD. TURNED ONTO MAIN ROAD AND TRIED TO ACCELERATE AND IT JUST SLIPPED INTO A LOWER GEAR WITH A BANG. NOT GOOD ACCELERATION. TURNED AROUND AND WENT HOME. SLIPPED IN AND OUT OF GEAR A LOW RATE OF SPEED. NOT SAFE TO DRIVE ON THE ROAD.

TL* THE CONTACT OWNS A 2016 HONDA ODYSSEY. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE HAD EXPERIENCED HARD SHIFTING WHEN SWITCH GEARS. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER (GERMAIN HONDA LOCATED AT 2601 S STATE ST, ANN ARBOR, MI 48104) WHO PERFORMED A TRANSMISSION SOFTWARE UPDATE BUT THE FAILURE CONTINUED TO OCCUR. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 30,000.

THE CAR SHAKES WHEN YOU PUSH ON THE GAS PEDAL

THE VAN JUDDERS PERIODICALLY AT SPEEDS BELOW 50MPH. THE JUDDERING IS BAD ENOUGH TO BE A SAFETY ISSUE. THE TORQUE CONVERTER SOFTWARE HAS BEEN UPDATED AND TRANSMISSION FLUID FLUSHED MULTIPLE TIMES WITHOUT SOLVING THE ISSUE. THE TRANSMISSION SHIFTS ERRATICALLY AND JERKS THE VAN RENDERING IT UNSTABLE. MULTIPLE CUSTOMERS HAVE REPORTED THE SAME ISSUE WITH THIS MODEL.

VEHICLE IS HESITANT WHEN ACCELERATING AND JOLTS WHEN SHIFTING AND DOWN SHIFTING. I HAD MY VEHICLE SERVICED FOR A SERPENTINE BELT AND I WAS TOLD THE TIMING BELT TENSIONER WAS LEAKING SO THAT HAD TO BE CHANGED ALSO. EVERYTHING WAS 'CHECKED OUT' BY A CERTIFIED HONDA SPECIALIST AND THEY DIDN'T FEEL THE ISSUE. IT'S BECOMING WORSE.

TRANSMISSION IS RANDOMLY SLIPPING GOING 30 TO 40 MILES IN TRAFFIC. ISSUE STARTED AROUND 15K MILES, CURRENT MILES IS 30K MILES. SINCE THEN, WE HAVE HAD THIS EVENT FOR ABOUT 12 TIMES IN THE LIFETIME WE HAVE OWNED THIS NEW VEHICLE. WE HAVE TAKE OUR VEHICLE TO SURPRISE HONDA DEALER BUT UNABLE TO DUPLICATE ISSUE AND DO ANYTHING. DURING THIS EVENT, VEHICLE WILL SHAKE, MAKE NOISE AND STALL. WE HAVE TO GO TO THE SIDE OF THE ROAD AND RESTART ENGINE. LATELY, WE HAVE TO RESTART ENGINE 3 TIMES IN ORDER TO RESET ISSUE. WE FEEL THERE IS A HIGHLY SAFETY CONCERN WITH OUR VEHICLE ISSUE SINCE IT STALL BETWEEN TRAFFIC.

THE PROBLEM STARTS WHEN SHIFTING FROM FIRST GEAR TO SECOND GEAR WHILE DRIVING AND WHILE SLOWING DOWN TO A FULL STOP. THE VAN JOLTS/ JERK. I WENT TO KUNI HONDA CENTENNIAL, CO. WHERE THEY VISUALLY INSPECTED AND TWO DIFFERENT TECHS TEST DROVE WITHOUT EXPERIENCING THE JOLTING. THE DRIVE HOME WAS WITHOUT INCIDENT. THE NEXT MORNING MY WIFE EXPERIENCED THE SAME JOLTING / JERKING ON UPSHIFT AND DOWNSHIFT. THIS PROBLEM IS SCARY SPECIALLY WHEN YOUR DRIVING ALONG THE FREEWAY AND STARTS JERKING. THE SAFETY OF THE PEOPLE INSIDE THE VAN IS NOW UNSAFE AND IN QUESTION. HELP!!! THE DEALERSHIPS DON'T KNOW THE SOLUTION SO WE'RE ALL DEPENDENT ON HONDA MANUFACTURING ENGINEERS TO CREATE AND DISTRIBUTE A SERVICE BULLETIN NOW BEFORE SOMEONE GETS HURT! MILEAGE OF FIRST INCIDENT: 25,440

THE PROBLEM STARTS WHEN I'M SHIFTING FROM FIRST GEAR TO SECOND GEAR WHILE DRIVING AND WHILE SLOWING DOWN TO A FULL STOP. THE VAN STARTS JERKING, SPECIALLY IN UPHILL. I WENT TO HONDA BUENA PARK AND THEY REPLACE THE PRESSURE SWITCH UNDER WARRANTY. I PICKED UP THE VAN AND AFTER 1 DAY THE PROBLEM STARTS AGAIN. THIS PROBLEM IS SCARY SPECIALLY WHEN YOUR DRIVING ALONG THE FREEWAY AND STARTS JERKING. THE SAFETY OF THE PEOPLE INSIDE THE VAN IS NOW UNSAFE.

PURCHASED NEW 2016 HONDA ODYSSEY VAN IN MD IN DECEMBER 2016. 150 MILES INTO OUR TRIP HOME TO NC, JUST AFTER WASHINGTON DC, WE HIT STOP AND GO TRAFFIC ON I-95. THE TRANSMISSION STARTED MAKING CLUNKING SOUND AND SHUDDERING WHEN TRYING TO GO FROM 1ST TO 2ND (MULTIPLE TIMES). YOU FELT VAN WAS GOING TO BREAK AND THAT YOU HAD NO ACCELERATION. PULLED OFF TO SIDE OF ROAD AND TURNED OFF CAR ? NOTHING WAS NOTICEABLE. WENT TO NEAREST DEALER THAT WAS 5 MILES AWAY. TOLD THIS CAN BE NORMAL, AS VAN COMPUTER NEEDS TO LEARN DRIVING HABITS. LEFT DEALERSHIP, TRAFFIC WAS AGAIN STOP AND GO. WITHIN 5 MILES HAD SAME NOISE AND SHUDDERING, BUT THIS TIME GOT CHECK ENGINE LIGHT AND FLASHING "D" ON DASH. REPEATED AGAIN FOR 3RD TIME ON RETURN TO SAME DEALER. THEY EXAMINED CAR FOR 2 HOURS. CHECK ENGINE CODE WAS: P0796 - A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE C STUCK OFF. HOWEVER SINCE CODE DID NOT RETURN AFTER RESETTING, THEY COULD NOT FIX IT UNDER WARRANTY. WE CONSIDERED VAN UNSAFE TO DRIVE (REGARDLESS OF 4 HOUR TRIP REMAINING). WITH NO CHOICE OTHER THAN DRIVING UNSAFE CAR, WE TRADED IT IN AND SUFFERED SIGNIFICANT DEPRECIATION FOR CAR WE OWNED APPROXIMATELY 5 HOURS & 157 MILES. SEARCHES ONLINE AND IN THE NHTSA DATABASE REVEAL THIS IS NOT AN ISOLATED ISSUE FOR THIS MODEL, AND HONDA HIDES BEHIND ?NOT ABLE TO REPRODUCE? AFTER TURNING CAR OFF AND RESETTING THE CHECK ENGINE LIGHT. *TR

TL* THE CONTACT OWNS A 2016 HONDA ODYSSEY. WHILE DRIVING BETWEEN 15-20 MPH AND ACCELERATING, THE TRANSMISSION SHIFTED FROM FIRST TO SECOND GEAR. THE VEHICLE ALSO LUNGED FORWARD. THE CONTACT STATED THAT THE FAILURE RECURRED ON SEVERAL OCCASIONS. THE VEHICLE WAS TAKEN TO HONDA MALL OF GEORGIA (3699 BUFORD DR, BUFORD, GA 30519, (678) 805-8003) TO BE DIAGNOSED ON FOUR DIFFERENT OCCASIONS. DURING THE FIRST AND SECOND DIAGNOSTIC TESTS, THE MECHANIC WAS UNABLE TO REPRODUCE THE FAILURE OR RETRIEVE A FAULT CODE. DURING THE THIRD DIAGNOSTIC TEST, THE CONTACT WAS INFORMED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED; HOWEVER, TWO DAYS LATER, THE FAILURE RECURRED. THE VEHICLE WAS THEN TAKEN BACK TO THE DEALER FOR A FOURTH TIME TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE TRANSMISSION FLUID WAS DRAINED AND THERE WAS EVIDENCE OF METAL SHAVINGS IN THE TORQUE CONVERTER AND TRANSMISSION FLUID. ADDITIONALLY, THE CONTACT WAS INFORMED THAT THE TCM MODULE ALSO NEEDED TO BE UPDATED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 34,000.

WE STARTED HEARING A THUNKING NOISE WHILE IN MOTION COMING FROM THE LEFT FRONT WHEEL. WE TOOK IT TO THE DEALERSHIP WHERE IT WAS DISCOVERED THE FACTORY FORGOT OR NEGLECTED TO TIGHTEN THE LEFT FRONT AXLE NUT CAUSING THE AXEL TO COME LOOSE. IF THIS HAD HAPPENED AT HIGHWAY SPEEDS, THE DEALER TOLD US IT COULD EASILY HAVE CAUSED A VERY SERIOUS ACCIDENT. THIS IS A SERIOUS PROBLEM THAT MAY AFFECT OTHER VEHICLES.
