2019 HONDA PILOT Engine Problems

When stopped at a stoplight or stop sign, the car has an auto start/stop feature where instead of the car idling, it shuts off and then starts back up when the brake is released. The car stalls and displays several dashboard warning lights and will not start back up after it auto stops. After several minutes, I can usually get it to start back up, but it typically happens in heavy traffic causing a substantial safety issue.

No Restart After Auto Start/Stop Engages. On several occasions when coming to a full stop at a red light/stop sign or heavy traffic, the auto start/stop feature turns of the engine. However, when releasing the brake, which is supposed to turn the engine back on, the engine stalls and takes several attempts to restart the engine via the push button starter. Have taken the vehicle to our local Honda dealership several times. First couple of times they said it was a weak battery and they replaced it twice under the vehicles warranty. The third time they said it was our aftermarket forward camera that was causing interference and was charge by the dealer to remove and reprogram the "system". Fourth time they said it was a dirty throttle body and also had to pay to have it cleaned. Eventually found article on the internet from June '22 that there is...

The automatic start/stop system turns the car off at red lights, as it it supposed to. However, several times the car will not start when I push the gas pedal but instead the whole car turns off. It takes opening and closing the door while pushing the park button and the engine start button to turn the car back on. This usually occurs at red lights which is very dangerous.

Our 2019 Honda Pilot has issues when the start-stop is active. When we come to a stop at a traffic light, gate, etc. it often will not restart on brake release. This creates serious concern in heavy traffic and we have been close to being rear-ended at stop lights. To restart the car we often have issues if it stalls during this brake press and release. It seems to electronically show in park, but not able to restart since it is not in park. We also see the issue when brake is pressed and tries to restart based on time. There are various lights on when this occurs. If we don’t activate the start-stop we don’t see the issue. If we manually turn the start-stop we don’t see the issue. However we need remember to turn this off manually defeating the fuel savings. I believe we can replicate this.

In AUg 2021 when the auto stop engaged the car would fail to turn on. Errors would come on on the dash and while car would die at stoplight. Took to dealer and they could not replicate so nothing was done. This happened randomly and we would need to put in park, wait a while and turn back on. Then in Oct 2021 the battery died and they replaced under warranty. There was no issues until Nov. 2022. The same started happening. Again dealer could not replicate and nothing was done. They did note the 1 year old advanced battery was low and charge and have charged it.

Engine will not restart after idle stop engaged. Vehicle must be put in park, shut off, and turned back on for engine to restart.

All the lights on my dashboard were flickering and vehicle would not start. I was getting error messages on vehicle display that all my vehicle systems were offline. Vehicle started the next day, however at a red light my vehicle shut off and was no longer drivable. My vehicle died on the road and I was able to put my hazards on for other vehicles to go around me. We shut the vehicle down and approximately 20 minutes later the vehicle was drivable again. We took the vehicle in the next day for a full diagnostic. Everything came back normal and we read online that the battery may need to be replaced. Diagnostic said battery was OK, but we had it replaced anyway. I drove my vehicle that evening and while driving all my lights came up on my dashboard again. I pulled over, worrying that my vehicle would shut...

Our 2019 Honda Pilot will flash the brake for the front collision warning system when there is no oncoming traffic or even when the oncoming traffic is in its lane. It does not always happen, but enough to be an annoyance. It also tends, when stopped at a light, and the auto stop engages not to restart. The entire electrical system goes haywire and then dies. This includes the ability to use your 4way or emergency flashers. The car then has to be jumped or towed to restart the vehicle.

The vehicle is equipped with the Automatic Start/Stop feature. Three times in the past few months, the car has unexpectedly stalled at a red light in the middle of traffic, creating a hazard for us and drivers around us. The electric power steering system warning light came on momentarily, and the display screen said ‘Radio not available”. We were able to turn the car back on after a slight hesitation, but the radio and controls on the steering wheel stopped working. All controls, and the radio, were working again after leaving the car off for a few hours. The car was taken to our local Honda dealer, who did not find any diagnostic codes and was unable to duplicate the problem.

I was stopped at a stop light and the engine went into "idle" mode and then cut off completely and all power was lost. I put the vehicle in park and attempted to restart unsuccessfully. I was unable to restart the vehicle for several minutes.

The auto -stop feature is now completely defective. Since I hit 30,000 miles I have had issues with it infrequently completely shutting off the engine. Now the mileage is higher, the vehicle shuts off every time I stop at light or stop sign. I have approximately 56,000 miles on the vehicle. It has been regularly serviced at the dealership. I feel this is a major safety issue since other vehicles expect me to be moving one the light etc., changes. There are no warning lights or other symptoms prior to the failure.

NUMEROUS RESTART ISSUES WHEN CAR IN IN IDLE MODE STOPPED AT A TRAFFIC LIGHT OR STOP SIGN. APPROXIMATELY 6 TIMES, MY CAR HAS BEEN STOPPED, IN IDLE MODE, AND SHIFTED INTO "NEUTRAL" & STALLING. I'M REQUIRED TO PLACE CAR INTO "PARK", TURN ON POWER, SHIFT TO DRIVE IN ORDER TO ACCELERATE. MESSAGES REGARDING "COLLISION MITIGATION SYSTEM" AND ALMOST STALLING ALSO OCCURS WHEN CAR IS STOPPED IN IDLE MODE. MY BATTERY (OF LESS THAN 3YRS) HAS BEEN REPLACED AS NOTHING ELSE HAS BEEN "DIAGNOSED" BY HONDA. ALTHOUGH THESE ISSUES HAVE SINCE OCCURRED SINCE REPLACING MY BATTERY.

My 2019 Pilot continues to randomly turn off. This happens at stop lights mostly, but did happen while driving as well. Latest was at a gas station where it would not restart. Had it to a mechanic and auto zone and both said that nothing is wrong with the car.

The contact owns a 2019 Honda Pilot. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. There was no warning light illuminated. The vehicle was taken to the dealer on several occasions, and the dealer replaced the starter, the injector, the transmission fluid, and the transmission plug. However, the failure persisted. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 42,000.

The owns a 2019 Honda Pilot. The contact stated that on multiple occasions while at a stop, he released the brake pedal, but the engine failed to re-engage. Additionally, the contact stated that the transmission inadvertently shifted into neutral while driving. The contact stated that he was able to restart the vehicle after multiple attempts. No warning lights were illuminated. The first time the vehicle was taken to the dealer however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 52,000.

The car is equipped with a stop-start system that is supposed to shut off the engine when you stop (eg at a red light) and restart almost instantly when you lift the foot off the brake. The restart feature fails somewhat regularly, maybe about 5% of the time. It has happened for many years, and with increasing frequency as the car is getting older. Sometimes the restart has trouble, the car misfires a moment, but then the engine restarts, sometimes a bunch of unrelated warnings sound when this happens, the car reporting that the collision avoidance systems are now offline or similar. Sometimes the engine completely stalls and does not come back online at all; when this happens, getting it restarted generally means putting it in park, turning the car completely off, then starting it again, a process that takes 10-15 seconds. When this happens at an isolated stop sign...

Start/Stop (auto Idle stope system) function issue. I have several incidents where the start/stop malfunctions. The other day I was on a red light and when I pressed the gas pedal to start driving the vehicle hesitate to start and begun to move backward. This happened several time already.

Check engine light Code p219b “Check emissions system” Fuel injectors needed to be replaced at only 32,000 miles. Vehicle was out of standard factory warranty by 6 months but under 36k. Honda did replace them under the service bulletin. Just wanted to report so they hopefully keep covering for others as this is an expensive repair.

"Check Engine" light comes on, followed by "Emissions System" problem, then "AWD" problem, and also "Transmission" light with a message to pull over and find a safe location. Have brought in for the "Emissions Systems" problem and AWD multiple times, but problem re-appears within a day. Uploading one invoice of many.

While driving, a light came on for Emissions Systems Failure. The vehicle seemed to not accelerate properly like it was pulling. I feared for the safety of my children. This is our only vehicle. My husband took it to the Honda Dealership. He got told that there is an issue with the fuel injector and timing belt. After research, we discovered both these issues have been added to a Honda recall list for our year and model vehicle. When my husband asked the Honda Service team about it, they said yes, but our VIN isn't covered. We are having the exact same issues as the recall.

Auto start feature not starting engine once brake pedal is released after engine is turned off at traffic stops due to this feature. It takes 6 to 7 tries when this happens to get the engine started while all this time putting the occupants of the car in anxiety and putting our lives at risk to push the car to the side. This has happened repeatedly in the last few days. It has happened few times couple of years ago and I wasn't aware it was due to this feature unless it started happening last week.

In the past I have reported an issue with the auto stop to Price Honda. They sent me away saying nothing was wrong. Last night my car died while coming to a stop. No warning. No engine check lights. The emergency flashers wouldn't work nor doors or windows and I was stuck in the middle of the road with my children without Hazzard lights. No way to put car into neutral unless you have a special tool which even the Honda dealership couldn't help me with. This was not disclosed when we bought the car and was stuck in high traffic for over 2 hours until a mechanic came and finally got my car to start and move to side by switching the battery along with other stuff. He stated the battery should not have died in Drive and something is wrong. I see this is a known issue when...

On multiple occasions the auto start/stop has failed when releasing brake pedal vehicle will completely shut off and takes multiple attempts to turn back on. This is a hazard due to the fact that it has occured on busy streets and state highways. At this time vehicle has not been inspected by dealer we do plan on taking it in asap.

The contact owns a 2019 Honda Pilot. The contact stated that while at a red traffic light, the vehicle lost automotive power on several occasions. The vehicle was able to restart. The contact stated that while she was driving uphill and was stopped at a light waiting to make a left, the instrument panel displayed various unknown warning lights illuminated and the vehicle stalled. The contact stated that the vehicle was able to restart after attempting to restart for 5 minutes. The vehicle was taken to a local dealer and the contact was informed that the diagnosis was that her battery needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that as she was driving uphill and waiting at a red light the gear shifted independently into neutral(N) without warning lights that illuminated and the vehicle then lost motive power. The contact stated that...

Vehicle is equipped with auto engine shutoff when vehicle stops. It started failing and has caused the car to stall at red light. Purchased vehicle 4 months ago

When stopped at an intersection, the auto engine idle stop activated in my vehicle. When I let off the brake pedal, the engine of the vehicle did not start back up. Alerts on my dash came up instructing me to place the vehicle in park and restart the vehicle. It took two attempts to get the vehicle restarted. The battery light turned on when trying to restart the vehicle. There was traffic behind me and I had to turn on my hazards to alert them of me having troubles.

The auto stop start function is malfunctioning. When I start to go after being stopped at a red light, the engine often does not restart back up. The car shuts down and I need to put it in park and restart the car. This just started happening about a month ago and it is happening more frequently now.

The problem, I believe, it with the auto start/stop feature of the car. At least 10 times (starting in mid 2021), while stopped at a traffic stop, the auto stop feature enables causing the engine to stop when the brake pedal is pressed down. Upon taking my foot off the brake pedal, the car stalls and does not start up right away. This always seems to happen at a busy intersection, and I have to put on my hazards until I can get the car to start up again which takes up to 2 minutes. This happens in both hot and cold weather. The danger here is that I can be hit by another car expecting me to move and also causes me to block traffic in dangerously busy areas. The problem cannot be reproduced at the dealership as per the dealership. There are never any symptoms prior to the...

With the auto engine idle stop enabled, stopped at a traffic light and engine shutoff. When releasing the brake engine did not start and dashboard display said to put car in park and press start button. Followed directions and car did not restart until completing the park/start button sequence three times.

The auto start-stop system is not working properly. We have had several incidences when the idle-stop feature is on and we stop in traffic or at a stop sign or light and the engine will not start back up automatically. I have to go back through the whole process of restarting my car and there are times when it wouldn't start back up on the first try. This has almost caused a couple of accidents with the cars behind us almost hitting us as we are not able to move initially causing more traffic and opportunities for accidents. I took it to a Honda dealership and there only suggestion was to get a new battery. They said that my battery when tested was borderline, but there battery testing machine did not say that it needed replaced. It said to charge and retest. I pressed them for the details and said...

Fuel-saving stop-start system fails to restart. Car goes into neutral and has to be turned off and back on to restart. This happens when stopped at a traffic light. Low battery light ignites, seems engine doesn’t have enough power to restart when gas is pressed.

I was stopped at a stop light in traffic. The light turned green and I tried to hit the gas to go, but my vehicle turned off. I tried to depress the brake and push the start button, lights flashed on my dash but did not start my car. I tried again and nothing happened. Then, all lights on dash turned off when I tried again to start the engine. I waited a few more seconds and tried to start the car and the dash lights came on but still my car would not start. I continued to wait a few seconds and tried to start my car and it finally turned on after 15-20 attempts. I called the dealer and they said it's probably the battery. The car just had a new battery put in so it's not the battery. The car just passed inspection at the dealer's last...

On my drive home this afternoon the auto idle stop feature on my 2019 Pilot touring began to hesitate to restart after releasing my foot from the brake. The result was an orange warning light telling me that there is a problem with the collision mitigation system and a shudder before the engine would resume running. I had to turn off the auto-start feature to avoid stalling in rush hour traffic.

Car fails to start after a short drive and parked and always requires a jump start. Car also fails to restart after a stop/start at a complete stop! Has happened multiple times in busy intersections where you’re a sitting target for moving traffic. Always requires a jump start. Have checked battery many times and the battery checks out fine. Maybe electrical or charging system issue. Dealer can’t reproduce the problem as it happens sporadically. Can’t figure out problem and a hazard to drive with kids in car.

When coming to a stop, vehicle shuts off with brakes. Once brake is released the automatic restart will not engage. You are stuck in traffic and unable to start the car for at least a minute. Honda replaced the starter and the battery. With the extended warranty, the starter was covered after deductable but the batt cost almost 300.00. I have since been using the battery they said was no good to power my camper with no problem.

Auto engine shut off will turn off engine at stoplight but fail to restart engine when brake is released. Extremely unsafe. It has happened multiple times and each time we are afraid there will be an accident because we are sitting ducks and not accelerating when traffic expects us to.

this is my second complaint as the auto start stop has failed again. This morning on the way to work, the auto start/stop engaged at an intersection. When the light turned green and i tried to go, the car wouldn't turn over. Stranded yet again at another intersection. Have to go through the whole process of putting the car in park, restarting the engine manually, then putting back into drive. The process isnt as quick as you'd think. There is a delay in all of this. Honda refuses to acknowledge the issue and has left me with an extremely unsafe vehicle.

Experiencing auto start/stop failures with car. it engages so quickly even at a quick stop sign the car is shuts off (i think timing should be extended). The problem is when it comes time to start back up there is often several turns before the engine starts. This itself is a safety concern, as i am often not able to move when i need to. Two other separate incidents where the system failed completely: the car did not turn over after several times and just stopped. This happened on interstate 95 in traffic. I was unable to move for 30 seconds while tried to get the car started again. Honda refuses to do anything about it; their solution is to have me try to video tape it occurring, since there are no faults. i am not doing this every time i come to a stop with my 1 year old...

The vehicle in question has the idle stop function, which turns off the vehicle when certain conditions are met. Randomly, the vehicle does not restart on its own which forces me to power cycle the vehicle in order for it to start back up. This is a safety issue because the vehicle has been stuck in the middle of an intersection while I am trying to get it restarted. If the vehicle were to be completely disabled, I could be stuck causing a hazard at any given intersection. I have had the vehicle inspected and the battery tested, but everything checks out OK. I don't feel very safe when the vehicle can just shut off randomly and not restart. I have noticed sometimes, when the vehicle does restart, the dash flashes a warning that says, "Collision Mitigation Braking System Problem" for a split second and then it clears.

Auto Start/Stop capability not working effectively and causes safety concerns with my children in the car. There has been numerous times where the car will NOT start back up leaving me stranded in intersections/traffic. Sometimes I cannot get the car to start back up for a few minutes while I am scrambling to figure out what combination I need to get it to power back up. I hate this feature and makes me extremely nervous while having the little ones in the backseat. We have asked the dealership to disable this feature all together and they refuse, I know there is the button to press but it is not convenient to press that every time I start the car back up. Easy to forget, I hope no one is seriously hurt due to this issue.

The automatic start-stop system doesn’t turn back on after a complete stop.

The auto stop/start gas saving feature often results with the car being unable to automatically restart. When this happens, in traffic, I am forced to put the car in park, and hopefully, manually restart the vehicle. This has resulted in the need for roadside assistance, several times (the car requires a jump). I have sent the vehicle to the dealer multiple times, but they say they cannot find the problem or are unable to duplicate it. Once they tested for battery and electrical system for power leaks and such, and though the car is only 3 years old, it is on it's third battery. I have had to regiment myself to disabling the feature, before driving, to ensure the issue doesn't happen in traffic again, as it could result in an accident. The last time this happened was the first week of August 2022, but it has occurred NUMEROUS times,...

Today and yesterday, the engine cut off when the car came to a complete stop. I tried to recreate the situation coming to a stop randomly, but found the cutting out was intermittent. Upon reading the forums, I discovered others are having the same problem and that you are investigating whether it has something to do with the auto start/stop feature, so I am reporting my issue with you. Where the engine cut off, I was either at a stop sign or at a red light with passengers including small children, and it took time to restart.

At a stop light the my car turned off and did not come back on for 5 mins. I am aware of the auto stop feature for fuel efficiency but I was in a turning lane. I literally could have been in an accident. The car brakes were locked in could not even put the car in neutral or park the car was just off completely. No signs of over heating, battery failure, etc.

The contact owns a 2019 Honda Pilot. The contact stated while stopped at a traffic light, the vehicle lost motive power and stalled without warning. The contact was able to restart the vehicle and the vehicle was operated normally. The dealer was contacted and stated that the vehicle needed to be diagnosed. The manufacturer was not contacted. The failure mileage was 44,298.

The engine fails to restart on its own from a complete stop at a traffic light or road intersection with the Auto Start/Stop function engaged. I fear I will get rear ended due to this. Or shot b/c of crazy road rage people. We took it to the dealer and it could not be replicated so they could not fix it. no warnings prior It has happened multiple times.

Vehicle has auto idle feature that activates when car comes to complete stop. Typically, the engine restarts when you take your foot off the brake, however, there have now been three occasions that the system did not restart the engine and the car stalled. I have contacted several Honda dealers and they are all aware of this issue but do not have a way to fix the issue.

When the auto engine idle kicks in more and more often the car struggles to restart. A message quickly flashes about a malfunction but too quickly to read it. I disable the feature very often as I fear the car will not restart.

Stop/Start function for the engine is garbage. It happened 5 times already that the engine shuts down and the car wouldn't go at the red light or even stop sign. Every time it's scary, especially with cars behind me honking for me to go. Luckily, every time I was able to turn off the car, then restart it. I noticed that 4/5 times this happened was after I was driving for at least an hour, on a hot day, with AC on. Miniscule savings of gas are not worth the safety risks of this useless feature. And it seems that I am not able to deactivate the feature completely.

When the idle stop system is engaged and the brake is depressed to activate the vehicle engine to shut off (at a red light for example), sometimes when lifting your foot off the gas the vehicle does not restart as it is designed to. This leaves the driver stranded at a green light panicking to find a way to get the car started and other vehicles stuck behind the stalled car stopping the normal flow of traffic and causing a potential accident.
