When driving the car at a speed 30-40 miles, it causes a whooshe sound that you feel the engine vibrates and rattles ( after many months I found out it's a torque converter issue with manufacturing of the automobile.

I was moving out of a parking space and bam!...the drop of tranny fluid and radiator fluid on the spot. When I took it to a mechanic, they told me this was the 4th Honda car they have had with same problem, they found out in all cases it was the pressurized hose connecting these two important parts had corroded to the point of failure. I have been hearing more about this and it is now disturbing to me. In my case my tranny is fine and all I needed was a new radiator and all new fluids. The car was not able to move and that may have saved the tranny. Got it towed and fixed the next day by trusted shop even though it was almost 800 dollars.

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?

- Owings Mills, MD, USA

I have had to replace the torque converter twice on my 2004 MDX, with a third time being needed now. The replacement failed within 2500 miles and the new replacement is failing as well. I have also had to replace the engine mounts when the torque converter failed the first time. Three times is entirely too many. I am not replacing due to dealer requiring me pay. All service performed as required at the same dealer that I purchased the vehicle from as new. The current milage is 132,000.

I pulled up my driveway which has uphill grade then a flat area and was in my garage when I noticed that I had the keys in my hand. I turned around and noticed my car was drifting back down the driveway. I tried to jump back in the car to hit the brakes but thought better of it as it was gaining more speed. I let go F the front door and watched as it veered off the driveway and hit a tree and landscaping rock and end of driveway. What it. So I was able to take the key out of the ignition while the car while still in the drive position. I did not receive a recall notice until February. Acura has not been judicious in their effort to fix the damage that occurred to my vehicle due to a defective part.

Vehicle develops vibration and shutter in transmission/drivetrain at approximately 30mph along with fluctuations in rpms. Also, torque converter feels semi-locked at idle when in drive shortly after starting causing rough idle and stalls, and hesitation upon initial acceleration.

- Oak Park, IL, USA

I was driving my car about 35 mph and the transmission started slipping. I pulled over to the side of the road and had the car towed. The radiator fluid had leaked into the transmission, initially I had the radiator replaced and had the contaminated fluid flushed and replaced several times. I drove the car for several days thinking that had taken care of the problem- it did not!! I had to have the transmission replaced at 103,764 miles. The total cost to me for both repairs was $4519.09. Now I am finding out that has been a problem and I feel that Acura should have recalled all of the 2004 Acura and should pay or in the very least help with the cost of the repairs.

Internal leak in radiator causing a leak of coolant to transmission fluid and vice versa, damaging transmission and rendering car not drivable within moments.

- Weston, MA, USA

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!
