2005 Acura MDX Problems

What owners report

Owners of the 2005 Acura MDX most often describe transmission problems, particularly a shudder or grinding sensation at low speed and, in some cases, transmission replacement. Air bag concerns make up the second-largest group, largely tied to inflator recall notices and warning lights. Many complaints were filed between roughly 50,000 and 130,000 miles.

1. 1
   Transmission and drivetrain

   Transmission shudder, grinding or vibration at low speed

   • 67 complaints (37%)
   • median 76,000 mi at 5.9 yrs old (62 state mileage)
   • owner-quoted repair $3,000 (median of 11 quotes)
   • filed 2008–2021

   Owners describe a shudder, judder or grinding sensation that appears while accelerating lightly, most often somewhere between 30 and 45 mph, and sometimes a vibration at highway speed. Several say the dealer identified the torque converter as the source and replaced the torque converter or the whole transmission; a few report the symptom returned after the repair. Some complaints also describe hesitation, hard shifting or D4/D5 indicator lights blinking. Mostly reported between roughly 50,000 and 130,000 miles, often on light acceleration or a slight incline.

   What to check: Test drive at light throttle between 25 and 45 mph and listen for a shudder or groan; ask whether the transmission fluid has been serviced and whether the torque converter or transmission has been replaced.

   “2005 Acura MDX. Transmission problem. Seems others on the forums have complained of an intermittent vibration in the car, the diagnosis was the torque converter the other cars. I am having the same experiences these other people have had. ,however since I cant replicate the problem at the dealer no one is doing anything.”

   NHTSA complaint #10244368, filed 2008-10, 50,000 miles

   “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. …”

   Air bags

   Air bag warning light on or air bag deployment complaints

   • 34 complaints (19%)
   • median 131,673 mi at 11.0 yrs old (16 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2006–2023

   Owners report the air bag warning light staying on or flashing with someone seated, and some describe the passenger or side curtain air bags deploying without a collision or deploying during an impact in a way they found unexpected. In several cases owners say the dealer could not duplicate the light or told them the system was fine, while others mention inflator recall notices and warranty extension programs. Typically reported on higher-mileage vehicles, from around 85,000 miles into the 200,000s.

   “I called my Acura dealer service department (new york) on 10/23/14, and was told that there is no recall for my 2005 Acura MDX although the NHTSA lists that car in the takata airbag recall pages concerning exploding airbags. Why does the Acura service department refuse to fix the problem? Is it dangerous to drive, and, if so, what can be done to make Acura responsive? Thank you.”

   NHTSA complaint #10649473, filed 2014-10, 50,000 miles

   “Upon entering intersection after being at a complete stop, the vehicles driver side airbag randomly deployed. Vehicle was towed to Acura of ocean in nj at which point Acura regional service manager claimed I hit a stationary object (which was not the case). I would welcome an opportunity to speak with someone who specializes in the recent airbag issues with honda and the other car mfgs.”

   Electronic stability control

   Stability assist (VSA) braking on its own or pulling

   Mentioned in 7 of 60 sampled complaints

   Complaints describe the vehicle braking one wheel by itself, pulling to one side, or briefly losing control, sometimes with a grinding noise and the VSA light on. Owners often connect it to the stability assist control module or the yaw rate sensor, and some say the condition persisted after a recall repair was performed. Mostly reported between roughly 60,000 and 155,000 miles, at highway and low speeds alike.

   Recall 13V092000

   What to check: Ask whether the stability assist recall (13V092000) was completed and whether the control module or yaw rate sensor has been replaced; watch for a VSA light or unexpected single-wheel braking on a test drive.

   “I purchased this vehicle from a private auction in hesperia, ca around august of 2020 and I am currently the registered owner as of today. About a month into the purchase I notice the car jerk and brake unusually while in motion. I didn't know what exactly happened at the time so I ignored it for the moment. …”

   NHTSA complaint #11389579, filed 2021-01, 197,000 miles

   “The driver side front brake randomly applies even if you don't touch the brakes. It pulls into oncoming traffic. The vsa! Light comes on every time signaling an issue with the traffic control. There was recall that was supposed to fix the issue however it did not. It can occur at 70 MPH or 5 MPH, there is no rhyme to why it occurs however I fear for my wife and my children when it is driven.”

   Steering

   Steering loses assist or feels inconsistent

   • 22 complaints (12%)
   • median 122,318 mi at 11.3 yrs old (18 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2008–2025

   Owners describe the steering losing power assist without warning, and some report hoses or fittings being replaced with the problem returning. A few report the wheel seizing or vibrating, with the dealer unable to reproduce the fault or attributing it to tires. Generally reported from about 25,000 miles upward, most often well past 100,000 miles.

   What to check: Check power steering fluid level and look for weeping at the reservoir and hose connections; ask whether any steering hoses or the pump have been replaced.

   “The issue at hand regarding the vsa (vehicle stability) for which a recall had already been issued. My vehicle was taken in and received the recall. This however did not resolve the issue which is a serious issue many others I have spoken with face. The yaw rate sensor malfunctions causing similar but more dangerous situations than the wiring harness Acura claims to have resolved the vsa issue. …”

   NHTSA complaint #10744513, filed 2015-07, 108,000 miles

   “The contact owns a 2005 Acura MDX. While driving 55-60 MPH and when the brake pedal is depressed, the steering wheel shakes and vibrates. The dealer has had the vehicle five out of the eight weeks that the contact has owned the vehicle. After being diagnosed several different times, she was finally informed that the brand new tires were cupping and causing the failure. The current mileage was 31,000 and failure mileage was 25,395.”

   Transmission and drivetrain

   Hard shifting or seized gear shift linkage

   Mentioned in 4 of 60 sampled complaints

   Several owners report the shift lever becoming progressively harder to move until it seizes, with corrosion found on the shift cable or linkage at the transmission end. Others mention the shifter not operating as designed. Dealers in some cases lubricated the cable and the problem came back. Reported from roughly 65,000 to 155,000 miles, often in vehicles exposed to road salt and weather.

   Recall 12V573000

   What to check: Cycle the shifter through all positions with the engine off and on, and ask whether the shift cable and linkage have been cleaned or replaced.

   2 excerpts from owner complaints in NHTSA records

   “Gear shift lever became harder and harder to shift over the time and then seized. Noticed heavily corroded shift lever linkage at the transmission end. The linkage design seems to be a poor. Exposure to elements makes it to corrode and seize. I had to apply wd40 to loosen the linkage and then coat it heavily with anti-seize compound.”

   NHTSA complaint #10626482, filed 2014-08, 105,000 miles

   “The transmission gear shifts not smoothly, d4/d5 light blinking, won't excel when gas is applied, had to cut the car off, wait 5min, to drive for two blocks before having to repeat this process to get it home 12 blocks away, only would excel 20mph (bought it on wednesday, on tuesday of the next week, the problem began). The car has 127,000 miles and history of oil change/transmission services. …”

   NHTSA complaint #11098851, filed 2018-05, 127,000 miles

Buying note. A pre-purchase inspection focused on the transmission is worthwhile on this model year, given how often the shudder and torque converter repairs come up. Ask for service records showing transmission fluid changes and any torque converter or transmission replacement, and confirm by VIN which open air bag and stability assist recalls have been completed.
