“My wife tried to open the (powered) liftgate via the handle. The liftgate would not open this way. When she tried the remote, it opened it apx 90 percent of the way. When it reached the apx 90 percent mark, it seemed that the motor opening it jammed and the gate came down quite quickly, falling unexpectedly on my wife's back. I researched this problem and saw that there is an open investigation on this same matter (NHTSA campaign id number: pe11034).”

“While driving on the highway at approximately 70 MPH my wife's 2009 Honda Odyssey began to shake as I stepped on the gas the engine light came on and the vehicle lost engine power and I had to manually steer to the side of the highway.. Upon opening the hood I could smell that something was burning. The vehicle was towed 79 miles to my mechanic. I was informed that a spark plug blew out completely and a portion of that plug entered the cylinder and damaged the engine. The entire threading of the spark plug was damaged and melted into the engine. …”

“We owned a 2009 Honda Odyssey . This vehicle has been maintained well for years at Honda dealerships. I have purchased extended warranty for 120k miles on this vehicle since we were planning to use this vehicle for a long time. Last time I had any work done on this car was in 12/31/13 at a Honda dealership. It was a major service. We did not have any issue with the vehicle until the event that LED to the fire on the vehicle. As my wife was driving her Odyssey on I-280/ca-85, she stated that all the warning lights/gauge on the dashboard came on. …”

“The air conditioning (A/C) control relay on my 2009 Honda Odyssey failed less than 3 years after purchase, causing intermittent electrical problems that would prevent the car from starting. When the car's ignition switch is placed in the accessory I position, only the audio system and accessory power sockets should be engaged and able to operate. My A/C control relay failed in the closed position, causing the A/C compressor in my car to run continuously, even when the ignition switch was in the accessory I position. …”

NHTSA complaint #10488006, filed 2012-12, 46,000 miles

“On may 12, 2012, I was driving about 50 MPH when the van started to sputter. I came to a red light and the car acted as if it were about to cut off. The check engine light started blinking along with the vsa light. It rode very rough all the way to the closest Honda dealership as I was not in my hometown. They informed me that one of the spark plugs needed to be replaced. I went ahead and replaced all of them to the tune of $308.23. On november 23, 2012, I was driving about 60 MPH when the same thing happened. The mileage was 105,001. …”
