Shudder or vibration when accelerating by model year
What owners say
I have code p0740 which is tcc function. My trans is operating erratically and undriveable. After faithful service intervals the trans died in my car. Acura denies knowledge of the problem even though there are thousands of people their torque converter failed due to a design flaw. I was almost killed when the trans shuddered and stalled in the middle of the road. I am furious this car is expensive and no need for transmission failure at such low mileage. Please recall and help.
Shuddering and wash-boarding, due to defective torque converter. Acura mailed out transmission software updates december 2009 and november 2010 to address this on-going issue. I have kept mine and can send you the documentation on it if you would like to receive it. Neither software updates fixed the issue. Now they are saying we need to replace the torque converter. This is a well-known safety hazard (check out the internet forums on it) and can cause fatal accidents. Please consider a recall, especially in light of acura's knowledge of the issue and unwillingness to fix it the proper way by replacing the part. This cannot be fixed by a mere software update. This issue is just as big and on-going as the toyota issue. Please issue a recall on this issue. I understand that some of the acura sedans (tl's) also have this same transmission problem!!
My 2005 acura mdx drive train will make a "judder" sound and can be felt in the vehicle all while loosing acceleration at around 30 to 40 MPH. The resulting loss of acceleration leads to serious safety concerns while trying to merge into traffic on ramps. There was a recall regarding this problem from acura. I took the mdx into the dealer and they did a PCM program update. This seemed to fix the problem for about two months but now the problem is back again.
Hello, I am a very frustrated acura mdx owner. I hd purchased 2005 acura mdx brand new. I usd the SUV for 3 years when I started hearing a "vibration" or "judder"noise while cruising between 20-45 miles per hour. In december 2010, I received a recall and was very happy that the issue will be resolved. I took the recall notice sent by honda motors and went to the alhambra, ca acura dealership. The dealership updated the PCM a/t software . The cause in the work order was mentioned as product update - pm update for lock-up clutch function. Software update s/b# 09-037. I got it update within 3 hours and finally felt happy that my SUV will be running fine. To my utter dismay, 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 thesuv in case it will stop on freeway. The federal safety agency is a governing body to help such situation. I am pretty sure, this issue has been reported before in the federal safety agency web site. I earnestly request the federal safety agency to take this serious and possible life threatening matter with acura and make them accountable and responsible [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
My transmission failed . I drive an average of 80 miles to and from work. Most of it was highway driving. I would notice some hesitation at low speeds in about 50,000 miles but would go away. At approximately 100,000 miles the problems started getting more noticeable.the time leading to the eventual failure of my transmission was a shudder during low speeds between 20 to 40 miles per hour. Then hesitation during acceleration and then eventual slippage of the gears which almost cost me an accident because it happened when I was driving in the highway. Luckily I was able to exit right away and avert any difficulties getting help at the side of the road. I brought it to a dealership which recommended the replacement of the transmission.
Just purchased a pre-owned 2005 acura mdx on nov 3, 2010 with 67,500 miles. After 3 weeks of driving the vehicle, I started experiencing the same problem as many owners have reported - engine / transmission makes shuddering noise when accelerating between 30 - 45 MPH. The same noise occurs when the vehicle down-shifts or cruise at the same speed. The odometer was at approximately 68,000 miles when the noise started to surface. It's been only about 6 days since the problem started and the noise is becoming more frequent. Seems to be a common problem reported by many acura mdx owners, but after doing some research online I did not find a permanent solution. Seems that acura / honda manufacturer chooses to not be accountable and remains silent in offering a real solution or recalling the faulty components - very disappointing from a long time customer of honda products.
At speeds between 30-50mph when the engine is under a slight load and the rpms are attempting to hold between 1100-1400, there is a loud vibration and shudder. The rpms jitter back and forth jumping by about 100 rpms or so as it tries to hold a steady speed. I had it checked at a local transmission shop and they recommend that I replace the transmission because the problem will just continue to get worse until the transmission completely fails. The problem I'm facing with my 2005 sounds exactly like the problem described in the acura service bulletin for 03-04 models: http://ww2.justanswer.com/uploads/thebesthonda/2010-02-04_181956_b06-003.pdf.
My 2005 acura mdx is making a shudder or grinding sound between 25 and 40 MPH while accelerating. I have found that this is a common issue and is related to a faulty torque converter. The federal safety agency has issued a "service bulletin" for this exact same problem for all acura's for model years 2003-2004. This bulletin has not been issued for 2005. All should be recalled and corrected at acura expense. The federal safety agency item# ch.cfm 10022468 "torque converter shudder or vibration between 35-40 MPH" .
2005 acura mdx. A shuddering noise is heard between 35 and 45 miles per hour and the engine speed increases by a few hundred RPM. Most often occurs while holding this speed on a slight incline or level. Torque converter was replaced at 78,209 miles on 11/18/2009. This temporarily resolved the issue, but the problem recurred and the torque converter was again replaced at 89,370 miles. This failure rate is excessive.
Since my purchase of a brand new 2005 acura mdx from the dealer, I have performed all of the scheduled maintenance and over the last year the car has started to shudder or vibrate when it reaches @40mph. The car has @57k miles.
