Default 2012 Honda Odyssey compression breaking?

My new 2012 Honda Odyssey feels like the breaks are catching (slows in jerking motions) when I remove my foot from the accelerator when going between 15 and 35 mph. I had it checked out under a 30 day service warranty. The technician statement was "No problems found with front and rear breaks. Upon test drive experienced what felt like "compression braking," MAY be normal condition. No trouble codes or TSB's found relating to concern." Is this actually normal or is he just guessing?

The vehicle was bought from CarMax with 60 miles on it. Thus the service tech is most likely does not have any special knowledge of Hondas.

The reason we were given to get a new car from CarMax was that it was excess inventory from a dealership that was sold at auction to make room for new inventory.

The "jerking" is not severe, just rougher than I've experienced in any other vehicle I've driven. It's hard to describe, but it kind of feels like someone is lightly pumping the brake.

It's a Touring, but not an Elite. Are updates covered under warranties?

Well first I would say that a CarMax technician is probably not the most skilled in the world and unlike a dealership tech who focuses on only a few models, he sees dozens of makes and models. If he isn't familiar with the model he won't admit it.

To that end the whole scenario makes me a bit skeptical. A basically brand new car being sold by CarMax? A major shudder while driving? I suspect it may have a history. An accident, a lemon buyback, or just one that someone beat the snot out of. In any case I wouldn't underestimate how serious this could be. In fact in a best case scenario it may need major transmission work. Wost case it could have major chassis issues. In any case I would take it to a Honda dealership. If any of these scenarios are true then you may be able to return the vehicle or even have grounds for legal action.

Hello Angie,

When you remove your foot from the gas, and feel a jerking sensation= TCM's (transmission control module/ computer) programming kept it at 2nd gear.. The computer is more prone to keep you in a lower gear during deceleration or light throttle. It probably felt like you're in a stick shift car in 2nd gear when you decelerate. It is normal. However, you can talk to a Honda service advisor and he can have a tech re-flash the TCM with its latest update software. There were numerous complaints in 2011 on the 5 speed autos, so they remapped the shift parameters. You did not mention if you have a touring elite with a 6 speed. ???

Also, you have to get used to the cylinder deactivation mode. It will "hesitate" at times when you are at light throttle and accelerating slowly at highway speed.

I recommend an automatic transmission cooler. It will save you from headaches such as torque converter shudder and premature transmission symtoms.


TCM flash updates are covered for 3yr 36000 miles at ANY Honda dealer. Just call to schedule.

Good luck.

I hesitate to askI have recently developed a severe hesitation problem. Cyl 1 shows compression of 120. Other 3 have 150. If I squirt oil into 1, it also shows 150. There has been no change in compression or vacuum (18), but the hesitation and tom Honda 2 4 16 Apr 2005 04:42 pm
