Honda Odyssey: 1 second noise at 5 mph when started (started engine as well).
Hi.
I'm not a mechanic and havent done anything more complicated than oil change, but need to understand this: Two kinds of noises: First: 1) metallic trembling noise (guaranteed!) moving from parking spot at about 5-10 mph, going backward or forward , going straight ,noise - for less than a second ; this happens in the morning (car was left overnight), in the evening when moving from work parking; any other time I come to complete stop with gear in parking and engine stopped; noise is there, if going downhill in neutral (my parking spont is nex to the hill) with engine running or not running (here, after engine was running for a while and brakes work easy, couldns say the same about steering wheel); Second: 2) another kind of noise, but much quiter noise at 50-60 mph (constant) as soon as I stop accelerating and RPM drops to 1600-1900 from 2500; in this case noise is only heard when slightly pressing gas pedal (accelerating or maintaining speed going uphill), but RPM doesnt change; going to higher RPM gets rid of the noise (like if I have to pass noise speed range 50-60 mph, accelerating more intense - at 2500 rpm for instance - no such noise); Other info: 3) no infuence on noise when turning; 4) when pressing brakes hard - steering wheel is trembling, so looks like worn rotors; 5) left front tire worn much more than others; 6) Honda Service says it's not transmission (since I have extended warranty on transmission, I asked them to check it specifically) after 15- 20 mins road test; Thanks for your feedback. vj |

This sounds like an ABS self-test; my '95 Subaru does the same. Perfectly normal; it's *supposed* to do that. <snip> -- -Stephen H.

Some suggestions: - Check the heat shields around the exhaust pipe for looseness or damage. A noise at a specific RPM can sometimes be a heat shield vibrating. - Worn brakes. If the noise sounds like metal gently scraping, it might be the wear bar on one of more of your brakes scraping the rotor. - Belts. The ribbed accessory belts can make a metallic sounding noise when they get old and stiff. It sounds similar to a bad timing chain. The little ribs on the inside of the belt develop little cracks and they start making a "zing" sort of noise as the cracks move through the ribs on the pulleys. This noise tends to come and go at different RPMs. If your belts are old and you see cracking on the inside ribs, try new belts, they are ready to be changed anyway if they are starting to crack. > > Other info: > 3) no infuence on noise when turning; > 4) when pressing brakes hard - steering wheel is trembling, so looks > like worn rotors; > 5) left front tire worn much more than others; Have the alignment checked and the suspension checked for wear. Look especially for a sagging spring or worn ball joint at that wheel. I had a similar experience on my Acura TL that was caused by a failing upper ball joint, which in turn was caused by a weak spring (that corner of the car was an inch lower than the other side). The symptom was as you describe here - brakes chattering when stopping from highway speed with shaking in the wheel. After stopping from highway speed, get out and feel the wheels. If that one is significantly warmer to the touch than the others, you probably have a failing suspension part or sticking brake caliper at that wheel. > 6) Honda Service says it's not transmission (since I have extended > warranty on transmission, I asked them to check it specifically) after > 15- 20 mins road test; > > Thanks for your feedback. > vj |

According to some, it's caused by the torque converter lockup. Hasn't affected our Ody (yet). In fact, it's not even a problem. Bearman |

Don't have an Odyssey, but wife has MDX...
I haven't figured out WHO TOLD PEOPLE that whines, hums, etc. aren't NORMAL. Unless it is pretty loud. But there are sure a lot of whiners on this board. JM |

Any ideas if new rotors/drums can help? Second: There is some form of resonance happening in the engine compartment at 48-55mph on 4 and 5 speed Odysseys in top gear when Torque Converes lockup happens and thats a low pitch noise conducted to cabin through the shift cable. Two major findings - one dealer according to odyclub.com, tried to install a new "dynamic damper" - from Accord to tacke resonance, and another finding is here : http://www.hondalac.com/service/Bulletins/x02-048e.pdf Regards, vj |

Earplugs. Are you really that bothered by a slight noise that lasts for less than a second? Start worrying when you *don't* hear the noise after you start. > Any > ideas if new rotors/drums can help?
