2004 Acura MDX: grinding or squealing brakes

Filed Aug 23, 2016 · Transmission · CT

Torque converter issues. Looks like the widely known complaint about the torque converter and transmission issue in honda pilots and acura mdx. My acura mdx 2004 clearly has the grinding sound (intermittent) when driving 35-40 MPH. The issue was known by acura in apr 2004 (recall), we bought the car new in may 2004 and were never told. We now have 150k miles on it but we have had the issue for a while - when asking the dealer they said they could not hear it (it is intermittent) and ignored it - yes, it is commonly known to car owners but not the dealerships. I now have my kids driving this car but as of today I will take it back and give them my other car. Not safe for them to drive it. I know I have a lot of miles on mine, but the issue has been known by acura officially since 2004. It is all about the money. What to do - recall is closed, class action in ca is closed, dealers and acura/honda ignoring it. Help please.

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?

When driving at speeds about 30-50 MPH. The car shudders, rumbles, and makes a grinding noise when I accelerate. I need to take my foot off the accelerator to make it stop. It happen all the time and has been happening for a couple of years now and has gotten worse. Acura/honda are aware of the issue which is caused by torque converter, PCM and sometimes the whole transmission needs to be replaced. There are numerous complaints about this and it's odd that it has not been recalled yet, which can be fatal if the transmission fails on the road.

My car makes a grinding noise while accelerating at around 30 - 40 MPH. I showed to the acura dealer and they said that this is due to a bad torque converter. They also said that this has to repaired with my on my expense as I am out of warranty. I noticed that this is a common issue with most of the mdxs and various online forums have mentioned this.

Tl* the contact owns a 2004 acura mdx. The contact was traveling 50 MPH when the transmission exhibited a grinding sound as the vehicle independently decelerated and came to a stop. The contact did not have the vehicle inspected. The failure and the current mileages were 90,000.

Driving home after purchasing used 2004 acura mdx the vehicle was making a noticeable shutter/grinding noise between 30-45 MPH under light acceleration. Dealership diagnosed faulty torque converter and replaced at no cost. No approximately 11,000 miles later, the problem has came back with bad torque converter. Internet search reveals this problem is common with these vehicles. Would not have purchased if known issues before. These is an obvious design flaw in the power train.

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.

A rattling/shuddering/grinding is occuring when accelerating, and only when accelerating, between 30 and 42 MPH. It is a result of a failing torque converter. Problem only occurs while in d5.

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.

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.
