| Hello, i am a very unhappy frustrated 2005 acura mdx owner. my car 2005acura mdx at 82k miles, i noticed car shifting gear was not shifting smoothly. having difficulty while shifting gear & which went worse & very stiff. also, a grinding noise coming, while accelerating at low speeds ( 25-40mph). it started to happen almost every time i accelerate the car or holding this speed on a slight incline level. i have had my mechanic to look at it & was told this noise is a transmission/torque converter problem. it's common to acura mdxs. & also, advised to take it to acura dealer. on oct-2009 car was placed for service @ authorized acura dealer. where dealer state that it's out of company warranty. the gear shift cable as well as transmission was replaced with 3-year warranty acura dealer at my (owner) expense 5k. again, in june-2012 @ 89k mileages, same problem started. my car shift gear was not shifting smoothly. my car needed excessive force in order to shift gears. again, car was taken to an authorized acura dealer and the gear shift cable was replaced. dealer state that the gear shift cable was covered with rust. which i believe the failure was a acura design flaw. the vehicle was repaired second time at my expense($400.00) for the same problem or cause. recently, again (sept-2012) same strange vibration/grinding noise started. it sounds identical to the issue i was having previously. however, this types of failure recurring every few months later. unfortunately, i found the same problem still exists. it is very frustrating and feel very nervous while driving with my family. i even get scared to drive this acura suv in case it will stop on the middle of the way, while driving. i'm requesting you( nhtsa) to take this serious and possible life threatening matter with acura and make them accountable and responsible for it. *tr | |||

| While driving the suv in a busy street 30-45mph felt the vibration, grinding, the triangle distress sign came on and felt the vehicle is going to stall. managed to get the suv to the parking lot on the right side. the suv completely stalled there and we got it towed to the acura dealer. they looked at it and the technician gave us the initial diagnosis as radiator has blown coolant line , fluids have cross contaminated and will take a lot of time to bleed out, also possible transmission failure in the process would need to retest drive after radiator replacement to see if transmission works. *tr | |||

| Engine mounts on the acura mdx from 2003-2006 seem to fail regularly resulting in excessive torque on the transmission and potential steering input shimming. honda/acura is well aware of the early failure of these mounts per referencing tsb 06-014. further evidenced by numerous inputs of multiple mount failure within a year. this is a significant defect that honda/acura should address with either enhanced design or warranty. http://www.mdxers.org/forums/14-problems/29355-broken-engine-mounts-send-me-your-information.html | |||

| Grinding noise on acura mdx 2005 model. had the car for two years when problem started. the dealer could never identify the problem. only when the car was out of warranty did they finally say that the transmission had to be replaced. i am the original owner and my car has 75k plus, but this problem started way before. this repair will cost me at least $5000. i'm sure honda knew about this problem and decided to ignore it. i feel cheated! honda must take responsibility for selling faulty cars and not owning up to it. i'm a million percent sure the dealers also knew it and didn't say anything about it. they are negligent as well. i am sure i am not the only one with this complaint. | |||

| Dt*: the contact stated while driving 20mph the airbag light illuminated without warning and the engine stalled. the engine would not restart and the battery was discharged. afterwards, the airbag and tire mounting light illuminated. the vehicle was seen by the dealer and the battery was replaced. the dealer determined the navigation unit was draining the battery. the engine stalling persisted and the vehicle lost all power. the engine was restarted but continued to stall. the vehicle was towed to the dealer who determined there was a short within the airbag srs module wiring. although the airbag problem was corrected, the stalling continued. the vehicle was taken to the dealer for further inspection, but the dealer was unable to duplicate the stalling problem. | |||

| It's unfortunate that honda motor co has not takenany corrective action to address the numerous probles with its acura mdx transmission problem and i am calling for a full federal investigation along with a potential class action suit against honda. a vehicle of this calibre on a luxury line, costing thousands of dollars is supposed to live up to its repuatation. to be further proactive, i ask all the mdxers for us to start a chain blog for acura and the other car manufacturers to see how extensive these problems are. acura has been less trhan cooperative during my interactions with them. so first let me talk about the problems and issues on my mdx. it started with grinding and whining noises coming from my 2005 mdx while still under warranty. i brought it in to open road acura of wayne, nj several times to fix the problem but issue still remain today. finally, i was told that the transmission would need to be replaced at my expense to correct this problem. when driving 50-60 mph, whining noise from engine area develops. it can be unbearable sometimes, sort of what you experience with earaches on a plane. the engine idles rough, in a grunting way. initially, constant noise came from the tensioner pulley. i paid and got that fixed even though this was a recall issue. two weeks into buying the car brand new, something in the drop dowm dvd screen was rattling and i got that fixed. then, the dvd/nav frooze on me causing yet another repair and time lost. so, now back to this transmission problem. i contacted acura hq and they asked me to contact the dealer. i asked for them to initate call to dealer but said they were't allowed to do so and all repairs is at discretion of dealer. now what happens if car seizes while i'm driving causing serious injury or death? acura has refused to even call me back as a courtesy and has never done so with its customer. this issue should be covered under warranty but dealer claims its at their cost. dealer service is good, policy is bad | |||

| 2005 acura mdx rear main seal failure around 70000 miles. most of the maintenace is conducted by owner with genuine acura parts purchased on-line at bernardi acura, massachusetts. notice oil stain in garage around 70000 miles, now at 76000 in dripping so i took it to dealer in fayetteville, nc for inspection and repair. asked for help from manufacturer to mitigate cost but was denied base on dealer service history. have read more complaints in forums. to me this is a defective part. to replace a $10.00 seal cost over $1000.00. | |||
