I was driving on the highway at 65 mph and all of a sudden the engine cut off. I lost engine power and the car began to slow down. After pulling to the side of the highway, I was not able to put the car in park nor remove the key. After several minutes, I was able to put the transmission in park and remove the key. The car started again after 10 minutes and drove it to the repair shop. The shop could not replicate the problem and said my car is fine. I know the car is not fine because it cut off on me while driving on the highway. This car is an accident trap waiting to happen.

I have 2001 Acura MDX with 80,000 miles. While the dealer was doing a routine oil change I was told the front and right side motor mount need to be replaced and cost about $700. I could not believe it! then I went online to research the issue, I found many people purchased this model car have the same issue (see this link: www.topix.com/forum/autos/Acura-MDX/T54qbspdkrmccnv0A/P8).

2001 Acura MDX with about 80,000 miles has cracked front engine block and bad side engine block. Dealer wants about $800 to fix. Numerous complaints on the internet of the same problem. This is a design flaw that Acura should fix.

Motor mounts going bad and breaking in MDX Acura 01-current. Replacing between 40K-80K. Intake system clogged (airport) gives bad gas mileage and to unclogg runs $200 at dealership. Makes vibration and noise as if you are going over a speed bump heading towards a toll booth.

Engine mounts failed. Car has 71,000 miles, and the engine mounts failed. This has been a serious problem well documented across the internet by hundreds if not thousands of 01 MDX owners. I believe it to be a design flaw.

2001 Acura MDX vibrations lead to dealer/ manufacturer to Focus on other components then the true issue. Were different finds stated to divert attention of know problems, to minimize financial and reputation" (lemon laws or poor design run around") I'm not the primary driver and then when I drove it (my wife is the primary driver), same problems were felt and it only had dealer service since purchasing it in 2001. I investigated the noise myself on 7/15 /2007 and noticed the motor mounts were broke. How long were they like this, who knows, but a noticeable engine vibration is gone after I pointed this out to the dealer/ manufacturer and had it repaired. I asked for reimbursement for the motor mounts from the manufacturer since it is a documented problem. The manufacture, Acura/ Honda, would not reimburse due to the age and mileage. I paid for the replacement of the motor mounts. A vibration was occurring around 30 - 40 mph, dealers/ manufacturer state it was a egr valve not allowing transmission to shift smoothly, and it was due to running below grade gas. Premium has and was ran, yet the transmission was 1.5 quarts low of transmission fluid, where is it going" is it heating up and pushing back through the egr valve in gaseous state and then cooling, clogging the intake, thence effecting the shifting? there is known issues with the transmissions and the dealer/ manufacturer should replace it and step up to the know issue. Lastly, the sway bar has been lose and I've been told it was the A/C compressor to a strut. I got under the vehicle and was able to identify it the first time. Is the manufacturer hiding know issues on these items stated above"
