My 2021 Honda Pilot se fwd would not restart after the auto off/on turned my engine off at a stop light. Of course this happened at a busy intersection causing backup and an unsafe environment to get out and inspect the vehicle. The car had to be jump started by a kind individual.
The contact owns a 2021 Honda Pilot. The contact stated that while at a complete stop with the start/stop feature activated, the engine shut off while depressing the accelerator pedal. There was no warning light illuminated. After waiting for several minutes, the contact had to perform several procedures to restart the vehicle. The vehicle was initially taken to a dealer where a software update was performed; however, the failure returned weekly. Recently, the contact stated that upon restarting the vehicle after the failure, the vehicle began to jerk while accelerating, with an abnormal tapping sound coming from the engine. The vehicle was taken to a dealer and was diagnosed with a defective engine rod bearing. The contact was informed by the mechanic that the repair could not be warranted. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 15,000.
All I did was simply change my battery. Up until this point the car had run perfect and no issues or warnings. Now after placing the correct agm battery the dash has lit up like christmas. I am getting acc, lkas, auto head light, forward collision and brake system warning lights. I was informed that this is a very costly repair, a camera needs to be replaced and recalibrated, $2000 estimate. This should be a recall based on the other numerous complaints I'm seeing. I reached out to Honda with no response as of yet.
The auto idle stop (ais) feature on my 2021 Honda Pilot intermittently causes the engine to shut off at a stop and fail to restart. When this happens the vehicle remains completely unresponsive until I shift into park and manually restart the engine. This has happened multiple times in traffic and at intersections, creating a huge safety risk. I have already replaced the battery and had the latest software update installed at my local Honda dealership, but the issue persists. The problem is intermittent and difficult for the dealership to replicate. The auto idle stop issue is a known problem with Honda even extending a warranty coverage for the starter assembly and starter relays. The NHTSA number ea25004 addresses this yet the local dealership will only update the software and change the battery. They are failing to honor the second stage of the repair calling out specifically replacing the starter assembly, starter relays and adjusting the valves.
The following warning lights: adaptive cruise control problem, lane keeping assist, collision mitigation system, road departure mitigation problem, auto high beam problem.
My 2021 Honda Pilot has a recurring electrical/network communication failure that causes “network communication lost” and “most net off” messages to appear on the infotainment screen. When this occurs, the infotainment system malfunctions, audio becomes unavailable, and the backup camera display is lost without warning. The problem is intermittent, unpredictable, and has occurred numerous times. The loss of the backup camera is a serious safety concern because it occurs while the vehicle is otherwise operating normally. During reversing, rear visibility is reduced, increasing the risk of striking another vehicle, pedestrian, child, cyclist, or object. The error messages and loss of infotainment functions also create driver distraction and raise concerns about the reliability of the vehicle’s electronic systems. I reported the issue to an authorized Honda dealership multiple times. They recommended replacement of the audio/display unit, and I paid for the repair. However, the same failure returned. The dealer later advised that the root cause may involve wiring, most network components, or another electrical defect and estimated approximately $3,000 in additional repairs. Despite multiple visits and approximately $983. 29 in diagnostic and repair costs, the defect remains unresolved. Honda service bulletin 20-058 describes similar most bus symptoms, including communication errors, loss of audio, infotainment malfunctions, and multimedia network failures. My vehicle exhibits the same symptoms. Because the dealer-recommended repair failed, the problem appears to involve the vehicle’s electrical communication network rather than a single component. This recurring defect affects the backup camera, infotainment system, and other electronics relied upon for safe operation. I believe it may affect other 2019–2021 Honda Pilot vehicles and may represent a widespread safety defect. I request NHTSA investigate to determine whether a recall / other corrective action is warranted.
Auto start/stop feature turned off the engine at a stoplight. When the light turned green and the brake pedal was released, the engine did not restart. There also appeared to be some sort of electrical malfunction since the start stop button would not turn off the ignition system in an attempt to reset the vehicle. This happened on a light regulated highway with a posted speed limit of 55 mph.
The bcm body control module is not working. My wife is scared to drive thinking it can turn on lights wipers and other components. For being a farley new car it’s crazy to think it’s defected. I had no warning prior to the incident. Honda dealer says they don’t know what caused it the alarm goes off all the time so I have to have it in the driveway with the battery unplugged Honda charges me $2,100 to fix it which is absurd.
The contact owns a 2021 Honda Pilot. The contact stated that while temporarily stopped at a traffic light or a stop sign, the vehicle occasionally shifted into neutral, or the vehicle shut off unintendedly. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 68,000.
No fireno injuries0 deaths0 the collision mitigation braking system problem, adaptive cruise control problem, lane keeping assist problem, road departure mitigation system problem and auto high-beam problem. All these are keep showing on my dashboard. It is stated that this is the multi point camera radar avg cost repair 2000. Oo.
Vehicle when trying to start locks up, have had the battery alternator starter checked, changed the brake switch and still having issues with hard start to my 2021 Honda Pilot. When this happens all the lights come on. I push the idle/start switch when I do get it started so that it does shut off when I’m at a red light or stop sign. Because I’m afraid it will not start. Dealership could not find any issues with the vehicle, I’ve taken it to another mechanic and they could not. It has been put on diagnostics several times. I keep putting money into trying to find out what the issue is!!!.
This seems to be an on going problem for many Honda owners according to the forums. My adaptive cruise control, lane keeping assistant, collision mitigation, road departure mitigation, and auto high beams have all gone out after going to the car wash. I have cleaned the windshield but I find it crazy that this is a common problem and there is no recall.
The camera in the windshield used for collision mitigation, cruise control, lane keep assist, auto high beams, etc. Has been found to have gone bad and need replaced by the Honda service center near me. The dashboard indicates all of these issues and disables the use of these safety features. The cost to repair is $1900 which includes camera, installation, and calibration.
The car on multiple occasions (4 separate incidents) after stopping at a red light or stop sign and the auto stop system stopped the engine, once the brake pressure is released, the car would auto start then immediately shift into neutral and completely shut off (engine, electrical, etc). Driver would have to coast/stop at side of road and turn car off and on again. In 2 of the incidents, this happened on a two lane road and completely blocked traffic until the driver could figure out what was happening and restart the car.
The side curtain airbags deployed while I was sitting in the passenger's side of the car looking into the glove compartment for about ten minutes with the car being completely off and parked in the driveway. The ignition was off and there was glitching and clicking sounds seconds before the airbags deployed. This could have happened at any point while driving on the street or the freeway. It could have caused an accident and could have killed me if it happened elsewhere. It could have been the passenger's side airbag that deployed and I could have been seriously injured. This incident happened on a Sunday, so I had the car towed to Honda the following day. Honda's response after investigating: "we contacted american Honda technical support. Our american Honda district rep informed us to have the customer contact her insurance provider for repairs. " aside from this official response, I was told that they investigated what they could and found no reason as to why the airbags would have deployed. I was told I had two options. Pay for repair with them or report it to the insurance. I stated that the release of the vehicle was a liability if I decided to not pay for repairs with Honda. After some dialogue, they helped with a loaner car and did not release the car to me. There were no warning lights or messages on the dash whatsoever. About a month prior to this incident, the car started alarming randomly. The random alarming would stop when disconnecting the hood latch sensor. I took the car in for a diagnosis and Honda reported that the cause of the alarm was the keyless access unit. The car (screen and dash) would still glitch after the hood latch sensor was disconnected. My hope is that Honda & american Honda admit responsibility & provide a solution not only for me but for all Honda Pilot owners that may be in danger. Investigating should be a priority, but even if repairs are done to my vehicle, I no longer feel safe driving a my vehicle.
Engines sometimes fails to start again after being turned off briefly. Will have so turn off all electrical and push button to start multiple times before it engine starts again.
I have had numerous issues with the car stalling while in idle- it will shut off but still display all the warning lights on the dash. It would require the car engine to be restarted. Has happened at stop signs, stop lights, carpool lights. This has happened at least 10 times over 3. 5 years. Last week I had a similar issue but this time it was much scarier- it did that same shut off but completely shut off the engine. All systems were black and the start button did not trigger a response for at least a minute. Once it finally restarted it displayed a “lost power” message on the screen. More similar issues to report.
After contacting the dealer several times, I’ve been told the parts for the recall are unavailable and it has been more than 6 months. The recall is over air bags that may not deploy correctly. Additionally, the electrical panel is periodically going out, the electrical on the seat isn’t working, and the car charger isn’t working. Finally, the car hesitates when going from reverse to drive. It won’t go and then I have to press the accelerator hard and then the car jumps. This is after I’ve had the radio fixed for incessant crackling from a different recall. The car seems unsafe.
Autostart failed several times then starter ultimately failed. Taken to dealer and repaired at my cost.
None of the safety sensors were working.
The sensors stopped working when the infotainment screen went out. It goes out all the time. Honda knows of this issue but does nothing to repair.
Screen stopped working suddenly. Will randomly flash bright blue or a gray static, then go back to black.
Audio and backup camera panel popping noise and disconnects whole panel causing it to go black , which includes the backup camera. Extreme safety issue with no backup camera .
While driving at freeway speed the gauge cluster including speedometer, gear selection, and navigation system shut off. The speedometer area was blank and the navigation screen said "network connection lost" no most network. It began to come back on a minute or 2 later. The most cable recall work has been done.
Brake system light on, adaptive cruise control problem and road departure mitigation system problem error messages. Brakes light turn on randomly, even when car is off. This intermittently causes issues with acceleration pedal not responding while driving as well as being able to start vehicle without depressing brake pedal which is a major danger if kids are inside and pushes the button. Unable to accelerate when needed also causes problem that can lead to a crash.
Our vehicle continues to randomly turn off and not go while driving. Whenever the idle start/stop is engaged, the vehicle will randomly not restart when traffic is moving. When this occurs you must completely turn off the vehicle, wait a few seconds, restart the vehicle, wait a few seconds, then attempt to place back into drive before being able to move. We have been having this same issue many times now. We have taken our vehicle in to the dealer service department multiple times with this issue. We have replaced the battery ($400) and it still happens. They act like they have never heard of this happening to anyone before and we must be "making it up". They then proceed to tell us that we need to let it keep happening until it is much more common. Then bring it back in again so they can see it happen. I complained to Honda USA with the same story, being that it keeps happening over and over, and they gave us the same answer. . . "wait until it happens so the mechanic can see it" as if it has never happened to anyone else before. This is going to end up causing people serious harm or worse. Honda is obviously trying to play down the issue to avoid cost at the expense of consumers.
Infotainment screen goes blank all the time. Nothing at all on the screen including back up camera. Now it is causing the other sensors not to work so you don't know if you are close to hitting something. Honda has had this issue now for years.
The infotainment screen was black and not working at all so no back up camera. Also all the sensors warning you that you are getting to close to hitting something stopped working.
While driving the cmbs (crash mitigation braking system) turns on at random timed intervals causing sudden breaking and jerking of the steering wheel towards center. This causes severe safety issues including increasing the chances of a wreck due to wheel jerk movements during turning and sudden breaking. The cmbs error message pops up on the touchscreen and during the episodes of sudden onset the entire digital display both on the gage cluster and entertainment center go black and an audible clicking is heard in the steering column.
Center infotainment system screen shorts out and goes dark. Back up camera will not work and it is unsafe to back up as you can't see below the rear window.
Infotainment system is crackling through the speakers and then the whole screen goes black and nothing works including the back up camera.
The infotainment system has some major wiring issues that cause the screen to go black and disconnect which then renders the back up camera useless. There is a potential class action lawsuit over this issue. Lots of Honda Pilot owners have this same issue.
Auto start-stop system failed. The car completely shutoff when the engine idle was engaged in the middle of traffic.
The truck lights came on, with no reason, acc and lkas dealer wants to charge 200 just to diagnose, I keep hearing many have thir problem, Honda needs to fix this problem that they know they have.
Infotainment systems makes a crackling sound then the whole system will shut down and screen goes black. Nothing with the system will work including the back up camera.
