On three different occasions, I have brought three different Honda vehicles in for service with horrible experiences each time.
1st time I took in my 06 Pilot. They had it for three days, charged me over $100 for a diagnostic fee and a shop fee and had no clue what was wrong with it. Gave me back my car in the same condition. After thinking about the issue more on my way home, I took it by an Advance Auto Parts store and they diagnosed a bad battery in less than 5 minutes.
2nd time I took in a 2007 Odyssey for a problem with the automatic door on the passenger side. They changed the mid roller and that didn't fix the problem. Charged me over $250 for that unnecessary repair. Then they wanted to change another part in the door for $350. I asked them if they were sure that this part was the problem. They said they "think so". They thought the first part was the problem too. I purchased the part from an online Honda parts store and replaced it myself. It was not the problem. I then googled the door issue and found dozens of repairs pointing to a $25 part that is probably the easiest part to replace in the door. I purchased it and replaced it in 30 minutes. It fixed my problem. I refuse to pay for the service department to "shotgun" repairs and expect me to keep paying for their guesses.
3rd time I took in a 2012 Odyssey for front brakes. I specifically asked for them to turn the rotors because they were very warped. The vehicle shakes violently when you step on the brakes. They changed the brake pads but did not turn the rotors even though I specifically asked for them to be turned. I called back and asked about it and they said they only turn the rotors if they are bad. I told them again that they were very bad, maybe need to be replaced. They told me I could bring the car back and pay another $159 to have the rotors turned. I went to Firestone and had them turned for $65.
It is irritating to me that I can find more information on the repair of my Honda's online than their Service Department knows and is capable of. I have been using the local Nissan dealer and they are much more knowledgeable about my Honda's than Honda is.
