2002 Honda Odyssey acceleration problems

Filed May 29, 2023 · Acceleration, Engine · CA

I've noticed that while driving the vehicle maintains speed/accelerate (without gas pedal pressed, and with cruise control off). I have to constantly fight the vehicle's constant acceleration with brakes. While idling, it keeps going to high RPM and then reduce and then high RPM.

On 9/10/14 I started noticing transmission slipping/down-shifting at 40mph/2k RPM many times during a less than an hour drive. Rpm would suddenly jump to 4k, and then comes back while the car suddenly jerks/slows as if it's put on engine brake. Vehicle is 2002 odyssey and has 69k miles. Took the car to honda dealer where the car has been serviced for years and they were able to reproduce the issue, and I was told it requires a new transmission which would cost $3700 for a reman transmission with 3-y/36 kmil warranty. Talked honda america and tried to "seek goodwill assistance for transmission" per some recommendations. They took my info, and details, and eventually told me they reviewed their parameters, and decided this is not a case they are willing to assist. Checked my maintenance record and was able to find a recall repair performed many years ago. I searched online and found there are tons of such transmission issues reported on honda odyssey. In some cases, there seems to be require a transmission replacement every 50k miles or so. Apparently honda has been knowingly selling such defective transmissions for many years w/o telling the customers. I'm disappointed to say the least at honda america, and the so called honda quality which is proved to be a costly myth. I have a hyundai with close to 90k miles and so far I don't have any transmission/engine issues. I think I'm done with honda.

When slowing the car (pulling into the garage and pulling into a parking spot) the car has accelerated when I have applied the brake pedal. This has happened multiple times. The incident was reported to our local honda dealer. They said they were not aware of any problem.

I was entering an interstate on a crowded day with construction cones on the side of the road. I had to accelerate quickly to get into a lane, and hit the gas pedal. I let up on the pedal once I was on the highway, but the pedal was stuck. I tried to pull it up, but it would not move. I could not get over, as the shoulder was blocked, so looked for an exit. I tried to shift into neutral, but it did not slow the car when I did. The only success I had at all in slowing the car (I was going 70mph when it stuck) was in holding the brakes, which I did. I finally saw an exit where I could get off, and I did, holding the brakes as hard as I could while throwing the car into park and killing the engine. It was only by turning the car off that I was able to stop it. When we started the van later, there was a horrible smell (probably the brakes), but the pedal came unstuck. My mechanic discovered that the cruise control had gotten stuck, and he disconnected it. It is the most terrifying car experience I have ever had, and I am only thankful that I was alone in the car, and not with my children. I was incredibly lucky, was completely traumatized, but have had to get over it because my job requires a great deal of driving. I don't trust my van, even though I know the cruise control is not connected. What else will it do now!? I have been unhappy with visibility in this van, already, and this confirms that I will never again purchase another one.

When we are going uphill from full stopped it seems the transmission is not picking up and it sounds like slippage of the gear. Then the yellow check engine indicator lights up and when we got home I grabbed my code reader and says p0730 incorrect gear ratio and p0505 idle. There is no crash but almost because the car behind us are really fast going uphill and because im not pressing the brake so most likely he didn't see that were are not moving with the current flow of traffic plus it happened at night at around 11:05 pm after I dropped off my wife to work. My foot is in the gas pedal when I noticed we are not accelerating no matter how much you press the gas pedal. All you can hear is slippage of gear but idle is going up without power.
