Vibration, humming noise while in eco mode. At slower speeds while feather gas, eco can sometimes seems to get confused abruptly turn off causing a jolt like feeling. At times, eco seems confused whether to fire on 2, 4, or 6 cylinders and can become in almost what I call an arrhythmia type feeling, with the vibration jumping around until it finds what it wants to do. Noticed the issue since I drove it off the lot. As expected, dealer says they can't find any issue. Vibration can be so bad that I sometimes think it is the road, but it is not. Would dump car but would loose money. Very unfortunate and will not be buying a Honda again. If you are looking into one, please be sure to test drive at all speeds, especially cruising at slow and faster speeds. Cruising and feathering the gas is when you notice it most.

My Honda Pilot stalled without any warning and without any engine lights appearing while driving on two way side roads and entering a highway. Emergency brake release handle was not working or releasing the brake appropriately same day. Honda can't replicate the issue so they say the car is to go with me. No explanation for incident. Manufacturer had them put something in the computer to read 15 second prior to and after a stall. This is an unsafe vehicle to drive for me, my family and anyone around me if it is undiagnosed and unexpected. Power steering and brakes lost so risks are high. I run the risk of causing an accident, injury, and/or death to anyone in the car or others. I filed a complaint with Honda, [xxx] case # [xxx] without resolution and wastold to pick the car up from the dealership or I be charged a fee. The car was at bernardi Honda in natick and they did all they could to replicate and work with Honda, I was told by them to pick the car up or be charged a fee. They are aware that the manufacturer is involved. I went to pick the car up on Saturday November 2, and discovered the emergency brake release cord is still broken and there were scratches on my car. I left it there so they could order parts and fix scratches. Please assist if able. I read about two recalls by Honda for the Pilot and Odyssey regarding unexpected braking and how you assisted! thanks.

My 2013 Honda Pilot jerks and surges when eco light engages. I have taken the vehicle to the dealer twice, with a third trip scheduled and am told, "we can't recreate the problem." But, it does it all the time when I am driving, and appears to be a very common problem based on other complaints I have read online. This is extremely unacceptable and Honda needs to acknowledge the problem, as well as provide adequate repair. This impacts the value and marketability of the vehicle. I would get rid of it today if it wouldn't have such a negative monetary impact.

I purchased a new 2013 Honda Pilot ex-L on June 15. I noticed on my first trip on the interstate that the car hesitates when driving in eco mode. This is very annoying as it feels like the engine isn't getting enough gas. Had it checked out at the dealership and was told others had complained too, but this was a normal function, nothing could be done. I feel like I'm jerking down the road. I traded a Honda Odyssey, which also had eco drive, and I never had these issues with the van. I hate to drive this car!

The contact owns a 2013 Honda Pilot touring. The contact stated that while driving downhill at 65 mph, the vehicle stalled. The check vehicle stability assist warning light was illuminated and after the failure occurred, the check emission warning light illuminated. The vehicle was taken to the dealer, who stated that the engine had seized and installed a new engine, before even opening the hood. The failure was reported to the manufacturer. The failure mileage was 5,700. The current mileage was 6,000. Updated 08/06/13 updated 08/5/2013

This report is for a new, 2013 Honda Pilot touring model with less than 100 miles on the odometer and has continued since. After the car is warmed up, and when the eco light illuminates, there is a shudder or a low frequency, rumbling vibration throughout the vehicle. This was first noticed while on the highway with cruise control set, but has since been observed at multiple speeds with or without cruise control. The vibration starts when backing off the accelerator after reaching a constant speed and continues until the engine loads down due to a hill or further acceleration. This also coincides with the eco light turning off. It does not appear to be related to a shift point, because when the accelerator pedal is depressed, the vibration stops and the engine rpms stay constant. The level of vibration is not as intense as that of riding over rumble-strips, but the frequency is similar. The level of vibration appears worse at higher engine rpms.

At various speeds there is a very annoying shuddering and vibrating and growling at 45 mph to 68 mph. Just when your ready to have a smooth ride on the highway it begins to shudder in eco...on a straightaway while free wheeling and while I am on cruise control... if you accelerate or decelerate, it will cease for a second and begin again.. I have even stayed at 68 mph to see how long it would last on a straight away while it was shuddering....and it continued...until I decelerated.. I also get these small bucks and surges, . or a feeling of pulling me along but feeling like I am going to fall out of my seat at the same time..in eco. Until the shuddering stops and then it feels smooth again, for a minute....and then the shuddering begins again.... my tires are balanced and I have had an engine mount neutralizing... the Honda Pilot has vcm... it is very uncomfortable to your ears the vibrating...on top of your peace of mind on your way home from a day at work....looking forward to relaxing listening to the radio to ease yourself before you get home to your family life...wow...not relaxing at all !!! something is definitely wrong with my vehicle....

I purchased this vehicle (2013 Honda Pilot ex-L) on 11/26/12 and almost immediately began to feel an annoying vibration when the vehicle was in eco mode. This vibration can be felt in the steering wheel, console. Seats and throughout the cabin. It is most noticeable on level stretches of roadway when applying light pressure on the fuel pedal. The vibration or "flutter" diminishes when more pressure is applied to the fuel pedal. When taken in to the dealership I was told this was a normal characteristic of the vehicle. After contacting Honda customer care I was told it would be checked into and have heard nothing further.....

2013 Honda Pilot touring 4WD purchased on 2/2. brand new, only 5 miles. After 3 days of owning, my wife was driving to work in it, and the check engine light started flashing and the engine ran very rough. She pulled over, turned the car off and restarted it after a min or 2 of waiting and it ran normal. She then continued her drive to work without issue. A few days after that, I had the same issue. After about a week, I determined that after a cold start, if you went up to around 2800-3000 RPM, then engine would run very rough and check engine would flash until you shut the car down. Since I could replicate the issue, I called for a service appointment. Before we were able to get to the service appointment, the check emissions system light also triggered. On Monday 2/18, we took the vehicle in for service and got a loaner Accord. On Monday, the call from the dealer was, nothing is wrong. I asked if they did it after a cold start since my wife said that when dropping the car off. Uh, no, so they kept the car. Tuesday morning they said there was an issue. They told me that the oil pump in the vehicle was turning out too much oil pressure which was triggering some sensors in the vcm system. This was causing it to not work properly. They said they would order a replacement oil pump and I'd be on my way. Later on Wednesday, they called back to say they were on backorder and I'd have to wait a few more days. On Thursday, they called back to say they won't have a replacement oil pump until April. The Honda factory rep said to order a new shortblock as a replacement as it has an installed oil pump.

While slowly backing out of parking place into the street, the engine suddenly and unexpectedly accelerated out-of-control to very high rate. Caught off guard, the engine RPM was not noted, but driver quickly decided that the only solution was to turn off ignition. There was no mat on pedal, and driver does not operate brake and accelerator pedals with two feet. Engine re-started and functioned normally.
