  • Automatic transmission
  • 90,000 miles
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"

Safety recall on 2001 Acura MDX customer states that the transmission problem started in 07 and feels like Acura should pay for it because it falls under the recall from 04* the consumer stated when the recall was first issued, he took the vehicle to the dealer who determined that the transmission was not in serious enough condition to warrant replacement, but instead an oil kit was installed. On May 25, 2007 the transmission developed a problem with shifting. The vehicle would rev more off a start and switch hard into second gear, making pulling in front of a vehicle hard. The dealer installed a transmission at an estimated cost of $3000.

MDX 6-cyl

  • Automatic transmission
  • 132,221 miles
The 2001 Acura MDX started to have major transmission problems. Seemed like when I first start driving the transmission only went to second gear and didn't go higher. If I pushed the gas pedal the rpms went over 5000 at speeds of only 40 to 50 mph. Sometimes, it felt that the car was in neutral, and when there was a shift in gear the car jumped as when skip ping a gear while driving a vehicle with manual transmission. The whole experience felt like when I drove a manual transmission car for the first time and didn't know how to work the shifts.

MDX 6-cyl

  • Automatic transmission
  • 71,000 miles
Noticed transmission slippage in 4/06 on my '01 Acura MDX. Dealer not able to duplicate problem. Yesterday, 2/22/07 with 71000 miles, the transmission, will without warning, appear to suddenly down shift and engine will spike in RPM's as if thrown into neutral. This occurs while driving at 40-40 mpg and causing sudden lost of control due to the forward thrust of the down shift and loss of throttle control. Engine light comes on along with a flashing and D5 indicator light. Very dangerous transmission problem that needs to be addressed.

MDX 6-cyl

  • Automatic transmission
  • 105,000 miles
Transmission failure: Apr 15, 2004: My 2001 Acura MDX recall on the transmission campaign #04V176000. July 20, 2004: My Acura has 65,809 miles - lewis Acura in shelburne vt inspected transmission - and instead of replacing it they installed a "jet kit" to lube the gears and keep the transmission from heating up too much. I believe the transmission should have been replaced. July 16, 2006: Transmission is slipping and I have read many reports on line of other people who are having the same problem with their 2001 Acura MDX transmissions. These people too only received the "jet kit" and their transmissions failed. I have had cars for a lot longer and the transmission has not failed like this. There needs to be a better look into how Acura handled this problem and really fix the problem rather than putting a band-aid (jet kit) on it.

May 182006

MDX 6-cyl

  • Automatic transmission
  • 94,378 miles
2001 MDX transmission failed and was replaced with rebuilt transmission by dealer. This was after 4 visits over 9 months complaining about a shudder between 40 - 45 mph. Another repair shop (non-dealer) had diagnosed a faulty transmission on the first visit. Transmission fluid was burnt. Dealer refused to accept that diagnosis and replaced egr valve (had already been replaced once), 4th gear pressure switch, and one time claimed not to be able to reproduce the problem. Dealer denied knowledge of any history of transmission failures in this model, despite many documented cases which I discovered after the transmission failed. In retrospect, the car was obviously dangerous to drive the entire period from the first occurrence till the replacement. Acura cs has refused any sort of good will reimbursement, partial or otherwise, due to the fact that all service was not exclusively done at a dealer. Honda/Acura is stone walling the public about these transmission problems, and a dangerous and defective product remains on the market for each consumer to discover for him/herself. It is only good luck that none of my family was killed or injured, and it is just a matter of time before some unsuspecting person is. Please investigate and force Honda/Acura to do the right thing and recall these transmissions and replace them at their cost.

MDX 4WD 6-cyl

  • Automatic transmission
  • 88,000 miles
Transmission would repeatedly rev as if in neutral gear while driving in 4th or 5th gear at or above 30-50 mph. Luckily no accidents/injuries. Had complained to dealer twice previously about a burning smell coming from the transmission but no problems found and car was still drivable at that time. Failure occurred at around 88,000 miles. Entire transmission needed to be replaced. Seems to be a problem common with other Acura MDX 2001-2002 model years once the car is above 75,000 miles but Acura does not acknowledge it.

Acura MDX 2001 automatic transmission failure. Transmission seems to always get stuck in neutral while driving. Engine will rev very high until the transmission shifts gear. Each time the transmission fails the car is brought to sudden stop and then shifts gears then continues on moving. The transmission problem causes sudden stop when driving in both freeway and when go at lows speeds of 30 mph. The engine light warning lights up, the D5 gears starts to blink.
