Problems with 2004 Acura MDX POWER TRAIN

My 2004 acura mdx - has safety concerns around shuddering - grinding and vibrating within the vehicle when accelerating beyond 35 mph. there are several forums with hundreds of complaints listed from other various owners of the same model vehicle manufactured in model years 2003 - 2004. this safety issue appears to be an absolute defect that affects the driving performance of the vehicle. the stated repair cost range between $2,500 and $3,000. the dealer is not open to covering any o f the cost of the defect. *tr

My 2004 acura mdx has been diagnosed with a torque converter problem at 71,000 miles. when we are at low speeds, 35 - 45 mph the transmission starts to vibrate as if we are going over railroad tracks. over the past few months the gas mileage has dropped significantly to the point that we are have to fill up twice a week to drive roughly 150 miles. i have read hundreds of complaints from other 2004-2006 mdx owners with this same complaint. some 2004 models have been recalled but not mine. how can they only recall specific vin's and not the entire model year. this is a financial and safety concern, one because the vehicles gas mileage has dropped significantly and the transmission could lock-up or overheat at anytime. *tr

2004 acura mdx torque converter issue. i can feel/hear the vibration/shudder/grinding between 20-50 mph while maintaining the steady speed with light load. the same issue happened once when the vehicle was at around 45000 miles. the dealer replaced the torque converter under warranty. however, the same issue came back at around 75000 miles until now at 93000 miles. it was only noticeable at around 30 mph, but now can be noticed between 20 and 50 mph. *tr

2004 acura mdx failed torque converter, grinding at low speed 10mph-20mph. repairs ongoing car has been at dealer for two weeks. purchased extended warranty from acura and is supposed to be covered but warranty company dragging their feet. current mileage 90k no warning or previous problem. also rear main seal on engine being replaced which is immediately adjacent to converter. estimated cost to repair $3,500. *tr

Transmission growling noise and vibration between 35-40mph when accelerating moderately. *tr

When in d5 driving between 30-45 mph at 1500 rpms the transmission makes a vibration/dull-grinding noise intermittently. it seems to force itself into 5th gear at low-speeds, and then lugs the engine and returns to 3rd or 4th gear after a few seconds. its affects the performance of the engine, and is wearing out the auto-transmission quickly. why isn't there a recall for this issue if its as prevalent as it seems? i wouldn't have purchased the car if i noticed this problem before-hand. *tr

I bought an used acura from a dealer almost two years ago but 3 month ago the vehicle shudders or vibrates between 35 and 40 mph, as per diagnose of acura, they stated torque converter is faulty. however because car is not under warranty they don't want to cover problem no matter of the number of complaints of several people on several websites. *tr

2004 acura mdx transmission failure . 81000 miles with jerky action, smoke in the hood. smell of burnt oil. metal part under the part burnt as liquid. no coverage and 7000 dollar costly replacement. no warranty. *tr

After backing out of my driveway and shifting the car into d5 the transmission would not engage and was completely slipping. after shifting to a lower gear i was able to get the car to drive and then shifted back into d5. upon slowing and then trying to accelerate again the transmission again completely failed to engage and hat to be shifted into the lowest gear to re-engage the transmission. also, on several occasions while trying to pass other vehicles the transmission would again completely slip. also at points where i would enter traffic from a side street or parking lot as i have tried to enter traffic at an opening the transmission would fail to engage which has created very dangerous situations where we have almost been in a very bad accident. *tr

Transmission/torque converter vibration at 35-45mph. started at 70,000 miles. forced to replace transmission, acura should be responsible for this failure. *tr

Acura 2004 mdx torque converter shudder or vibration. *tr

My 2004 acura mdx has been making a grinding noise (as if going over rumble strips) when driving above 35 mph especially when driving on a curve. the pohanka acura dealership states that the torque converter is faulty. this particular problem is listed numerous times online for the 2004 mdx. acura has not placed a recall apparently because they do not see it as a safety issue. they will not admit to have used a faulty part in building this particular model. highly disappointed with this type of business practice. where is the customer service they rave about? they are asking for over $3k to replace the faulty part. i am going to research some other avenues before i make my final decision. *tr

Sudden transmission failure on the highway. lose all power from the engine to the wheels. has to pull over suddenly in traffic to avoid being hit by other cars traveling at normal speed. the transmissions on honda/acura v6s apparently have systematic problems. *tr

Tl* the contact owns a 2004 acura mdx. while traveling at 15 mph, there was an abnormal grinding coming from the transmission. in addition, when accelerating at 15-40 mph, the grinding would stop. the vehicle was taken to a local mechanic where he was informed that the transmission would need to be replaced. there were no prior warnings of the failure. the vehicle was not repaired. the failure mileage was 91,000 and the current mileage was 105,000.

2004 acura mdx with following issues: horn, cruise,audio not working. transmission bad motor mount bad. *tr

I went to drug a store and was in a hurry when i parked the vehicle. i left the car in "drive" as i was in a hurry and didn't notice. i was able to turn off the ignition and remove the key, which didn't register to me as a problem at the time. when i came out of the store, i found the vehicle had rolled backwards and struck another parked vehicle, causing approximately $2200 in damage to the other vehicle. minimal to no damage to my vehicle. when i got home i was able to duplicate this situation. *tr

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: http://www.aboutautomobile.com/complaint/2005/acura/mdx/automatic+transmission http://repairpal.com/debris-in-transmission-due-to-failed-torque-converter-clutch-006 http://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! *tr

All acura mdx have the following problems- and all are very expensive to fix. acura dealers and corporate does not care to listen- because we fools keep buying there cars. - all transmissions will fail very early. cost (4,800) - all motor mounts will fail (1000) - horn, cruise, audio controls will fail. ( 400). plus lots of other issues. *tr

My complaint is about my 2004 acura mdx the torque converter makes the grinding noise that most owners are dealing with i feel that acura has not accept responsibility for this defect. *tr

2004 acura mdx, started to shudder/vibrate/grinding noise noticed just after 50k miles. the problem occurs when driving between 25 to 45 miles, trying to coast or decelerate. also observed the sudden hesitation of the vehicle when the shudder occurs. if i put it in d4 (instead of d5) then it doesn't seem to be making the grinding noise/vibration. i have reported the issue around 50k+ mileage to the dealer but dealer said they can't reproduce/identify it. i have complained about the same problem in 2 other visits to the acura dealership, every time they denied the problem. now, at 90k miles i complained about the problem and this time they were able to hear and observe the sound, exactly the same as i have been reporting since it had 50k+ mileage. acura dealer is saying the whole transmission (torque converter) has to be replaced. for a vehicle that costs $40k having transmission issues at 50k mileage is unacceptable. i don't drive it rough and don't neglect the maintenance. there are so many complaints in the online forums on this exact transmission problems. acura/honda customer service is very poor or non-existing, they should be ashamed of such a problematic component in a luxury vehicle. *tr

Torque converter failed, causing a total need for transmission replacement. *ak

Our 2004 acura appears to be very sluggish and slow to accelerate in 35-40 miles range and was pulling to the right. so, we took it to acura dealership in los gatos, california on 1/27/2009 for further investigation. that's when the dealer recommended a new transmission without any mention of the existing recalls on the 2004 acura mdx transmission problems. *tr

After shifting out of reverse into drive, the vehicle continued in reverse until the consumer turned off the vehicle and restarted it. dealer was notified. *jb

There is a consistent metallic clanging/rumbling at 2,000 rpm in any gear, particularly under part throttle/light load operation. *jb
