I have a 2017 Honda ridgeline. Up until a few months ago, it had been perfect. Have always taken it in for scheduled maintenance, etc. 45,000 miles on it. About a month ago, it started jerking pretty violently occasionally when it shifted from around 2nd to 3rd gear (it’s an automatic). The weird part is, it wouldn’t consistently do it once the car was turned off and on again. I feel like driving up hills would often “set it off,” and then it would continue to jerk for the rest of that ride. But if I turned it off and turned it back on, it seemed to work perfectly until a ride or two later. Around this time it was due for service, which included change and transmission fluid, and as I was driving it in to get serviced, the “D” on The dashboard had an X through it, and it told me there was an omissions system failure and transmission system failure. I brought it into the Honda people, they reset the computer, said it was a computer update issue and told me everything was fixed. It did the same thing a week later with the system failure message. Brought it back in, they updated it again and said that they missed an update the last time. It had been working well for a week, but then again tonight it started doing the jerking again. It is still under warranty, so I’m not worried about whatever the ultimate cost of fixing it will be, but I am getting frustrated that they have never fixed the problem and I am wondering if it needs a transmission rebuild/replace. Anyone ever dealt with anything like this, or have any idea what the problem might be so I don’t sound like a dumbass at the service department? TLDR: Honda ridgeline with transmission issues, dealer hasn’t fixed the problem. Wanting alternative ideas.
