Transmission slips, and hesitates to shift normally and then goes normal again. Vehicle is in motion when this occured, it happened while crusing at 35 mph, and at 50 mph, street, and highway. I have taken it into the dealer multiple times to find the issue and anyways end up with no answers, I have been able to find multiple people with the same make and model that have the same issues with their vehicle. I bought this car with 25,000 miles and it now has 125,000 problem has not gotten better or worse has been the same. The brake warning also pops up randomly when no other cars are near.

Torque converter shutter at speeds of 30mph - 45mph causing erratic acceleration fluctuations. I addressed the concern with the dealership at around 72,000 miles (just out of manufacturers warranty). I told there was a fluid recall. They changed the fluid which remedies the issue. The transmission fluid has to be changed every 5,000-10,000 for the vehicle to perform with a less noticeable transmission shudder. Manufacturers recommends changing every 30,000 miles to prevent transmission slipping. I did contact Acura and they dismissed my concerns, stating I drove the vehicle too much. After researching online this seems to be a common concern/problem other Acura MDX owners are experiencing.

While car is shifting idle hangs and shutters around 1600-2000 RPM. Left front and rear shocks have loud noises when traveling over bumps.

Appears to have issues shifting from D4 to D5 or while in D5. Roughly around 1.6K RPM the vehicle sounds like it is driving over rumble strips. I think it might be a torque converter problem.

Vehicle shudders at 35-40 mph, the shuddering is harder when going up a slight incline. It seems that the vehicle doesn't want to shift down a gear. I have to either let go of the gas or give it more gas for the shuddering to stop.

Bought our 2015 Acura MDX less then 6 months ago from a certified used Acura dealer. Last week, the ems, power steering and transmission light came on. Car stays in first gear and jerks while driving. Speedometer is weird. Brought to Acura dealer, of course the lights were off by then. Was told we need to do special transmission flush. A week later lights are lol back on! I drive my kids to and from school and don't feel safe anymore with my car

Car started to drive 'jumpy', the local shop did diagnose a transmission issue about which Acura had a service bulletin- at low speed or at sudden acceleration car would drive uneven, interrupted; at constant hwy speed there would not be a problem; check engine light turned on emission system problem. Local shop did regular maintainence as the service light had turned on, diagnosed the fault in concordance to Acura's own service bulletin however upon travel to Acura dealership this was 'not reproducible'. upon returning home car started again to interrupt without check engine light on. Dial of RPM jumps up and down without remaining even ata constant speed. Car has new spark plugs, oil, filters, however the local shop has deferred the rest for the dealership. Acura dealer in savannah explained that the issue is in fact not a 'recall' and I should bring the car back if it does the same. However per bulletin the coverage lasts for cars up to 80K miles and mine started this at 79+ and by the time I would drive back to the nearest dealership it would probably exceed 80K miles, which they said they would take into consideration should this recur. Obviously the issue is known but because it is not a official 'recall' they would do nothing.

When opening the automatic trunk it starts coming and falling down rapidly as to almost have our heads trapped. It's a death and injury awaiting to happen. I have contacted both Acura dealership and Acura customer care and they refuse to notate this safety issue and resolve. They want me to pay for a new part when in no way did we cause this malfunction to ocurr.

The contact owns a 2015 Acura MDX. After parking on an incline, the vehicle started to roll forward and crashed into a garage wall. The contact sustained two fractured ribs and contusions that required medical attention. A police report was not filed. The vehicle was taken to the dealer. The technician was unable to diagnose the failure. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 24,000. Updated 09/20/16 updated 09/26/16.8jb

Transmission jerks (badly) around 3rd gear, in low speed.

The Acura MDX 2015 can be turned off while in drive and the car rolls backwards as if in the neutral position. Pull into a parking space and forget to put the car in park, but push the engine start button to turn off the car. The car will roll backwards. The car does not lock into place. This is a serious safety concern if a person was behind the car they would get run over. The Acura corporate office took the information and told me to call the dealer. The dealer said that this is a known feature of the new car.
