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

| 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, | |||

| My mechanic determined my front and side motor mounts need replacing, and mentioned it being common in my vehicle. i've since found others with acura mdxs with the same problem. never needed mounts replaced in any other vehicles owned. i believe it to be an inherent defect acura must address. | |||

| Took car in for inspection and the dealer told us our front engine mount needs replacing. never had to deal with this with our previous cars. shouldn't acura take responsibility for their mistakes. *tr | |||

| 1. the front and side motor mounts on my '04 acura mdx are broken as well as the rear a/c blower. problem was first diagnosed by a private mechanic who was replacing the brakes for us. aside from the brakes, the auto has been dealer maintained incl. oil changes. acura confirmed the diagnosis and refused to offer any good will discount for the repairs. 2. front mount broke first, followed by the side (within 2-3 wks.) due to the additional strain placed on it by the front mount not functioning. 3. nothing as of yet. still attempting to appeal the decision regarding good will assistance. i am in contact with the dealership trying to resolve, but not very optimistic. both motor mounts need to be replaced along with the rear a/c blower. *tr | |||

| On a trip to a car wash, my acura mdx got locked with the engine running which caused a back up on the line and loss of business for the car wash. i had to hail a cab to go home and get the spare key and compensated the owner for the loss. when i got home and read the owner's manual i was very surprised to find out that the vehicle can be locked using the master lock button in an open passenger door even with the key in the ignition and the engine running. it was then that i realized that the car wash attendant on the passenger side must have locked the vehicle. this is a flawed design and can potentially cause safety problems. i now have to carry a spare key when i go to a car wash. i brought this to the attention of the manufacturer and got no response. *ak | |||

| The check engine light frequently blinks and the car occasionally misfires while the car is accelerating or under heavy engine load (e.g., accelerating onto the freeway or driving on interstate through the mountains). these conditions appear to happen more frequently the whether is cool and damp. when the vehicle misfires, the engine hesitates and various dashboard warning indicators light. the engine hesitation and distraction from the warning lights makes it difficult to complete merger into traffic. | |||

| I bought a new acura mdx 2004 and in two days the engine malfunctioned, light appeared. i went to the dealer, who said that i need to make an appointment to fix the problem, eventhough as a new customer i was not satisfied with the car, indicating a problem within two days of driving less than 100 miles. i did some research on the problem and found that the issue i am facing is a known issue within the range of my vin number. but acura dealer and the customer relationship office in la denied that they know about the problem. i also found a similar the issue documented on your website. as a consumer what are my rights here ? a) can i get acura to provide me the level of quality and service i am expecting b) reject the product if they failed to notify me about the problem before i bought the product(fair disclosure) about the recall c) they didn't fix the problem before i bought the car, even though they were aware of the problem. i know someone who bought the *same* model car from the *same* dealership and their car also falls in the *same* vin range which is documented to have the problem. they told them that its a known issue when they called the acura dealer service, and ask them to come down for service. but when i ask the same question they deny knowing any issue with the car, they even showed me a print out which says nothing is flagged against my vin number. i have currently given my car for service, and i am on a loaner car from the dealer. still waiting for the car to be serviced. also i am concerned that if the problem reappears, it will further erode my confidence in the car and the dealiership. i am also extremely dissatisfied as a consumer and would like to know what should i do so that other acura consumers don't have to go through the pain like i am going throguh and also get compensated for the damages and inconvinience caused by this incident.*ak | |||

| The acuramdx that i bought is for model year 2004, there is kind of a loud droning noise from the exhaust system, that was identified by the reading honda dealer and furthur confirmed by the mfg's rep, but the problem did not get fixed since the mfg. has no fix for the problem and the mfg. is not willing to adress the problem or solve it or refund the money.*ak | |||

| A loud droning sound comes out at 2,000-2,200 mph, especially loud at approximately 40-45 mph. dealership and manufacturer say that this is a natural sound of the 2004 mdx. i do not buy this explanation it is hard to believe that an expensive suv such as this would have a natural sound like this loud droning sound. it is very loud especially during cold weather. they insist that this is related to the new dual exhaust system of the 2004 mdx. what if it is engine or transmission related? *ak | |||
