Won't start

Honda Accord 2015 4.3 138000 miles
My 2015 accord sport was running fine then the next day I went to start it and it crank up then spit and sputtered before dying and wouldn't crank back up. I had water in my gas tank so drained it and added new gas still nothing... The main chip in my ECU turned out to be damaged so got a new one but the car won't communicate with it. The honda dealership says it's acting like it's been struck by lighting which it hasn't... any suggestions??

From time to time when i press the accelerator, there is no immediate response. It may take another try to get the engine to respond. This mainly occurs when i need rapid acceleration from a stop to quickly get into traffic. I was told that the computer that controls the fly-by-wire accelerator takes time to coordinate with the computer that controls the cvt transmission. I have a safety concern with this. *tr

Supplemental restraint system indicator was blinking on and off, now it stays on all the time. Dealer said that the srs computer was not communication with the resistant system and the first step is to change the srs computer. If that doesn't work, the next steps are to replace the airbag senors in the seat or any sensor in that supplemental restraint system. The initial cost to replace the srs computer is $746.28. Dealer said this is a safety issue. Repair scheduled for 21-oct-2015. The problem started on 10-oct-2015.

I pulled up to park at a bike trailhead and as i touched the brake the accelerator went to the floor, lurching the car forward and forcing the left front tire over the railroad tie parking marker. The car high centered and i pressed on the brake pedal but the engine kept racing. I finally got the car in park with engine still racing and shut the car off. When i turned the car on again, it responded normally. I took it to my local dealer and there were no error codes in the car electronic system.

I was driving my 2009 accord on my snow covered street and the vehicle stability (vsa) light flashed on, as it should, when the vehicle loses traction. However, the light stayed on and the abs and brake lights both appeared as well and all 3 stayed lit. At first, i thought they would reset, but after a few days, they did not. The vsa and anti-lock brake functions were no longer working. My car was brought to a local dealership where they performed a diagnostic test and based on the computer codes, determined that the abs modulator needed to be replaced.

On two occasions in the last six months, my 2009 honda accord experienced what i would describe as unintended acceleration while operating the vehicle at a low speed (first time turning on to a road; second time accelerating while attempting to park the vehicle). The engine surged with power and nearly redlined the tachometer. Each case i shifted to neutral to disable the drive train and then shut down the car; waited five minutes and restarted the car. I scanned the ntsb data base to look for similar reporting but found none. I bought this car used, in 2014, from a honda dealership, with only… Read complete

My acceleration conditions/problems are identical to nhtsa id #10607907 & several others. Upon acceleration there is a severe hesitation to the point of almost stalling before it accelerates. At 15000 miles it appears to be getting worse. I was also told by a service rep this was computer controlled and not cable controlled as in the past. There definitely needs to be a fix to this as it is extremely dangerous pulling out in traffic. *tr

Honda Accord 2014 LX Sedan 2.4L CVT
I drove the brand new honda accord with my 9 year old son on high way 93 south in the middle of the lane. It was friday noon time, busy in high way. I felt something wrong with the car and tried to changed to slow lane. The engine stopped working with error code instead of "d" in the panel. There was big truck behind me. I pulled it over. It was within 24 hour after we picked up the car. It was scary experience! luckily, we are safe! even luckier, it happened when i drove it, not my 20 year old, inexperienced child drove. I could not imagine what would happen it occurred while he drove. Dealer told us it was regulator in the transmission system broken. They replaced the transmission as a solution. *tr

Problem 2013 Accord

Honda Accord 2013
I have had 3 (or 4) false low tire pressure warnings. The first 3 tines the dealer refused to do anythig other than check the pressure and reset the light. The last time i had an alarm i drove another 25 miles and then looked at the tires. I could see nothing wrong so i assumed it was another false alarm. This incident occurred on a saturday so the dealer was closed and i continued the trip we had planned. When i finally went to the dealer, it was 5 days and 300 miles later, the dealer did find a nail and the pressure was 24 psi. Now the dealer is telling me that he has researched the honda data base and/or talked to honda and there is nothing else they can do until i bring it in again with a false alarm. They will then connect the computer and begin a procedure.
