Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

There is a grind/ roaring sound when I am going about 40 mph. It definitely sounds like the transmission. I researched it on line and have determined that thousand of people like my self are experiencing the same issues, but Honda has not recalled these cars. My question is does someone's transmission have to cause an accident and possibly a fatality before this issue is handled. Most people have had to have the torque converter replaced at their own expense, some after threatening lawsuits have received some assistance. What can we do?

Reproducibly at automatic transmission shifting speeds between 20-25mph, 30-35mph and 40-45mph there is an audible and palpable shudder as the transmission hesitates prior to shifting. Have brought vehicle to Acura dealer 3 times over the past 5 years, every time stating the same complaint, and every time referencing a convincing multitude of Acura MDX owners noting a similar problem. Every time Acura service states they could not reproduce the problem and nothing is wrong with the vehicle. The last time I even drove the car with their chief mechanic, who verified the problem and stated it must be the torque converter, but Acura only performed an automatic transmission flush and reset the transmission computer settings that they charged me for, and neither solved the problem. This is a serious dangerous problem and eventually someone is going to get seriously hurt. Links with multiple owners experiencing the same problem and frustration: www.aboutautomobile.com/complaint/2005/Acura/MDX/automatic+transmission repairpal.com/debris-in-transmission-due-to-failed-torque-converter-clutch-006 forums.edmunds.com/discussion/12576/Acura/MDX/Acura-MDX-torque-converter-scam/P3 I also have in my possession an internal Acura memo detailing this problem. Many thanks in advance for what I am certain will be a thorough investigation!

I was pulling into drive way when I shut off truck took keys out, shut door, as garage door was opening. Car started rolling back... I opened door tried to press on emerg. Brake with hand as im running with vehicle as it is rolling back, wouldn't stop. I realized the gear wasn't in park, it was in reverse, but with no keys I tried to put gear into park, wouldn't move without keys, I hopped in, put keys in ignition and turned car on, as I was putting the gear in park, the vehicle reared forward and I pressed on breaks but it wouldn't stop. The car was moving forward as I was pressing on the breaks, needless to say, it did not stop until I ran into the garage door as it was coming back down, and both myself were half way into my son's garage door, wall, and shelving, items, all damaged by my rolling backward Acura......because the car was in a fast speed, I tried to avoid going straight into the garage, to avoid going into the bedroom, so I swerved inward toward the wall... the garage door would not lift up off the truck, so I asked my grandson to push on the switch on wall while I lift on the garage door, as we worked together with no keys in ignition, motor off, on the count of 5,4,3,2,1.....I lift, he pushes, and guess what......there goes M car.....starts rolling back...right into my son's [parked...vehicle....damage...3 claims in one day.....3 deductibles in one day......when I called insur...I was asked if vehicle was drivable?... when I started it. It made a loud roaring sound and would not go into reverse.......then I found out a recall was out on my vehicle.... and I hate to think that all the times I drove in the vehicle with my grandson.....I just had 2 back surgeries and 2 knee replacements, ... as I was running with my vehicle, I injured my back and knee and I cannot work for a while.. all thanks to Acura...

I had noticed a shuddering at 1200-1400 RPM. Dealer said it was likely the torque converter. Recommended not doing anything at this time. In the past month, I've had two occasions while in drive from a stop, when I stepped on the gas the car did not move; the engine just revved. The first time I put the car into park, shut off the car. I restarted and all was well. This next time I was going around a curve at about 10-15 mph, when the car revving response to my pressing the gas pedal, but did not accelerate. As if it had shifted into neutral. I switched into neutral and back into drive, and it re-engaged. Lots of similar concerns on my investigation on the internet. If this is a known problem to Acura/Honda, why has there not been a recall or a fix?

On 11.11.11, our Acura lost power coinciding with the dashboard warning lights not functioning properly to warn of the sudden loss of control, heavy smoke emission, transmission failure, engine damage & inability to drive our vehicle, creating the possibility of a crash, injury or fatality. Despite Acura's knowledge of transmission failures based on an Acura service bulletin alert, we incurred $5500 in expenses/damage to our vehicle.we had not been notified of the faulty torque converter/transmission parts previously&Acura has avoided taking full responsibility for a known problem in which many consumers have been fully reimbursed for this damage. We are issuing this complaint&requesting reimbursement for our expenses due to Acura's full knowledge of this recurring situation, their negligence in alerting consumers&their neglect in resolving the repair in accordance with their responsibilities.we would request that Acura be held responsible in notifying all Acura owners of the service bulletin/recall pertaining to this faulty transmission. We also feel strongly about the electronic/computer dashboard warnings that gave no indication of damaged or faulty parts creating the dangerous&unsafe situation we had experienced while driving our vehicle in traffic when this incident occurred&are filing a complaint according to the seriousness of this portion of the incident as well. We have much documentation&would be more than willing to provide whatever would be necessary to ensure that this complaint is productive in enforcing Acura's responsibility of these two incidents, to further make aware&avoid such incidents&in hopes of being reimbursed for our unexpected expenses as well. In purchasing an Acura, we had done so with the peace of mind that we had purchased a well made, safe vehicle from a company that stands behind it's product.we are saddened that this has not been the case.

I was told my radiator bladder exploded causing all fluids to mix, thus I now need a new radiator and a new transmission, cost of repair is $4600. My 04 MDX has 137K this should not happen, there are numerous cases of this same issue all over the internet Acura forums, why has there not been a recall on this issue, there is clearly an issue with the radiators. I need to have the radiator replaced, all fluids drained and then flushed 5-8 times to ensure all the contamination is gone, then new fluids put back in along with a replacement transmission. There has to be numerous complaints about this, please help!
