Noises During Shifting problems of the 2016 Acura MDX

Zf9 transmission went out at about 10,000 miles with metal particles found in atf fluid. Replaced by Acura with a new transmission apparatus. Apparently this is a rampant and dangerous problem with this model year transmission. Now at 38,000 miles (28,000 miles on the new transmission) this one is failing, slipping on shifts and making a squeaking/chirping noise between gears. Can result in failure to engage/accelerate in an emergency situation. Acura people won't take it seriously so NHTSA should get involved. A quick survey will demonstrate this is a common problem in this car. Acura has a TSB but this should be a recall item. They're trying to get beyond everyone's 6 year powertrain warranty without having to take action.

Uncontrollable acceleration, surging and bucking during braking or decreasing speed the vehicle hesitates to stop in all gears - uncontrollably dangerous acceleration also stresses additional vehicle functions - tires and brakes - suspension (inertia that causes imbalance) - steering - vehicle steering is now somewhat unbinding and veers right or left when attempts to control anomalous accelerations while braking or slowing the vehicle poor acceleration at lower city speeds and remains in erratic gears for unspecified times this is most dangerous when driving in rougher traffic and especially when there are additional demands to drive at elevating speeds transmission disengages briefly at higher speeds recently, as the vehicle increases velocity and consistency, the drive gear disengages to neutral for a few milliseconds and changes back to the drive gear and regains momentum transmission is noisy 1. Thuds and clicks while shift at various times 2. �cricket sounds� gurgling, creaks, grinds and mild knocking is present when idling and engaging after vehicle startup e. Manual transmission functions 1. Vehicle continues to move once parking gear is engaged and foot brake is released 2. Once vehicle starts, reverse and drive gear is "sticky� and makes noise (thud) when engaged.

My 2016 Mdx has had its transmission replaced twice. The symptoms are usually "chirping" noises and/or rough/violent shifting behavior. On the very day that I picked the vehicle up from the Acura service shop after its 2nd transmission replacement, the vehicle still wildly exhibited "chirping" noises, all of which are documented in a youtube video that we took while driving the vehicle home that day. Even after 2 transmission replacements, the transmission is beginning to exhibit the same symptoms yet again. This is a lemon transmission. This week, I had an independent mechanic who specializes only in Acura/Honda vehicles inspect the transmission. He documented the "chirp" noise as well as "harsh" and "erratic" shifting. This is all documented in writing on his work order receipt, which I can provide upon request. This mechanic also suggested that if the transmission fails, it could cause a catastrophic crash and potential injury or death to occupants depending on the situation. Prior to the independent mechanic examining the vehicle, my local Acura service shop gave me the "run-around" song-and-dance by saying they can't fix anything because they were "unable to recreate the symptoms". They stated this despite the fact that I have extensive video/audio evidence of the symptoms on youtube of my specific vehicle.

When driving the SUV after the second gear kicks in the transmission has a jolt and it feels like a lag in the shift but then pulls very hard. This shift pull happens when you are going 15-20 mph. Engine timing belt has a loud chirping noise.

Un intended non acceleration. Due to severe lag, delay, and sluggish transmission response. Acura has replaced my transmission under warranty at 11,000 miles and did not admit fault and say there was a problem. Here's more on my experience. . In my 1 year of ownership. . To whom it may concern: 2016� Acura Mdx 13,000 miles , purchase new from sierra Acura , alhambra, CA I am writing to request buy back of my vehicle this car is a lemon. Since taking ownership a year ago, my 2016 Mdx purchased new has experienced nothing but one problem after problem. Acura replaced transmission a month ago but the problem is still there. Is it engineered and designed to perform in a not safe manner ? many times I experience shifting and accelerating hesitation and jerky/jolting. My family and I do not feel safe operating and riding in this vehicle. Several times gas pedal depressed and vehicle lagged at 20 mph for more than 10 seconds before accelerating. A few of the latest new and ongoing problems are below. Driver door now appears off set and at different angle protruding out now. Appears that the door is not closing properly and therefore not sealed at closing. Furthermore every single window has experienced faulty mechanisms with motors, actuators, and seals. When closing the doors it feels like the windows are loose. There are also squeaks and rattles eminating throughout the cabin area. I secured and collected all loose items and the sound is still there. At engine start up each time, there is a high pitch whining noise for a few seconds before engine starts (perhaps something else faulty?) I have video / sound documentation of this with 2 seperate recording dates . With regard to the navigation, multimedia unit, it has been lagging, slow (er) to function, and severe delay in backup camera actuating, and audio functions delay in response sometimes.

We purchased a 2016 Acura Mdx with sh-awd. Within the first few weeks we noticed the transmission shifts were jerky and erratic. Most of the problems occurred when driving blow 40 mph. The vehicle also lunges forward unexpectedly when decelerating while your foot is off the gas pedal. It feels as if the car downshifts and you get some unexpected accelerating. We had issues with the transmission since the first few weeks, the dealership kept saying that it is an ¿adaptive transmission¿ and will get better after time. After a few months, things only got worse. The transmission would make a loud metal on metal noise when starting the car up. The vehicle was in the dealership for almost 3 weeks before they could identify and fix the problem. They ended up replacing the entire transmission December 2015 and we had to go back to have the transmission adjusted as it was shifting so hard that you would hear a clunk. The vehicle has never been the same and it does not feel safe to drive, especially in the winter. We are very careful when coming to a stop because you never know if it will suddenly lunge forward. Now 8 months after having the transmission replaced, the same noise is coming back. The car is back in the dealership and they were able to replicate the sound again. However, now they are telling us that it¿s a characteristic of the transmission and that 40-50% of all Mdx¿s with the 9 speed auto will develop this noise! they say it is due to the fluid building up at the bottom of the transmission and when it starts up the fluid gets pushed through all the gears. It sounds more like metal on metal to me and why was the noise not there prior and always develops after 6-8 months? I have not seen anything online regarding this noise that supposedly occurs to 40-50% of Mdxs.

Transmission failed. This 9 speed transmission has a fluid heater in it that has radiator water supplied to it. Car was not shifting correctly and making a beeping noise at 20 to 25 mph. Car was taken to dealer on 06/11/16 with 8,800 miles on it. They called to tell me that the 2 way valve between the coolant and transmission was faulty and coolant got into the transmission. Acura told them to replace the transmission entirely. Will take 2-3 weeks. Have been having issues the entire time we have had the car. When taking off the car does not accelerate quick, in fact, tends to stall then lurch. Have had issues with the sensors coming on, not sure if this is related to the transmission, but is a continuous issue.
