I am writing to report a severe manufacturing defect and safety hazard on my vehicle. The interior door panel trim has completely delaminated and peeled away from the door structure, creating an exposed, razor-sharp edge right near the door handle/window switches. This is a major safety hazard ("Safety Hazard") that poses a severe laceration risk ("Severe Laceration Risk") to any passenger or child attempting to open the door or touch the door panel. I have clear photo documentation of this sharp metal/plastic piece protruding dangerously out. I would like to request Acura Client Relations to look into this manufacturing defect immediately and provide a resolution/goodwill repair before a severe injury occurs. Please contact me via email to review the photos. Thank you.

I have experienced the vehicle not unlocking when the key fob is near(in my pocket) the vehicle and my hand is touching the door handles. The vehicle is designed to unlock when the key fob is in close proximity while hands are on the handle. This is a safety/security concern because in an emergency, the vehicle does not function as it is intended to.

The car alarm started going off randomly after the car was locked and armed. This would happen periodically. The car was locked using the indoor lock and then left unlocked and the lights would go off and on periodically. The internal dash periodically would flicker off and on (dash lights/screens). The car eventually drained the battery one night cycling down to 4.25v and had to be replaced (it was too damaged to be jumped). Upon replacing the battery codes were read, cleared and the car driven. The alarm and light issue came back, and the hood latch was disconnected. This stopped the alarm, but after rain events or humid days the lights would still come on (as if someone unlocked the car or walked up with the key) and the dash lights would occasionally flicker. The wireless control unit was removed and inspected and dendritic growth was noticed on one location of the board. This was cleaned with alcohol and this has appeared to solve the issue so far. The part of the board with the growth is not sealed and looks like it is right on the edge of the factory sealing.

The certified pre-owned (cpo) 2017 acura mdx I purchased ion 07/24/20 from davis acura in langhorne, pa should not be classified as a cpo! I paid my automotive repair shop of 20 years that maintained my lexus suvs to do their own 83-point detailed inspection on the acura mdx.I was shocked in their reporting wheel alignment needed - recommended left rear tire edge wear & body ' evidence of previous accident damage to rear bumper, right front door, left side doors, left rear quarter panel & left front fender. I was informed that at least 50% of SUV has been repainted & there was dirt underneath the paint. Was this formerly leased SUV in an accident that went unreported with clean carfax and auto check reports? The left door exterior chrome door handle was also replaced by dealership but no reason is listed as to why replaced. There are now issues with: exposed airbag ' is it the original or was it replaced?; tire pressure varies (+/- 7 or 8 ) in the rear left tire that has been looked at by my local acura dealer two times in one week & the 3rd visit will be to replace the TPMS sensors in a car with only 16,000 miles?; the defroster is not fully working in the left passenger window and the misalignment of the lift gate is a concern because it prevents the A/C or heat from working effectively in the 2nd & 3rd row, there is rain water sitting on the inside of the SUV that remains for hours. Could it mold or cause damage to the rear electric lighting components? How does the lift gate trunk door misalign if it wasn't in an accident? If the lift gate trunk door is misaligned, why was this SUV sold as a cpo & not used? I do not feel comfortable driving the SUV. I have yet to receive a call back by phone from acura dealership owner in 4 weeks and/or from the acura customer care specialist in the last 10 days about my case filed. Can the federal safety agency inspect SUV for damage & repainting?

All door locks, windows, trunk, fuel door, and sunroof does not work

Keyless entry communication issue on 2015 acura mdx for reference, key fob located in purse. Purse draped over right shoulder and resting against the car door, key fob not sitting next to a cell phone. Keyless entry will not unlock when handle pulled or lock when button on door handled pushed with index finger. To solve, key fob must be pulled out of my purse and lock/unlock button pressed. My purse must be placed against the tailgate door locking mechanism for the sensor to acknowledge the signal and unlock. My key is in exactly the same location it was the three years I owned my 2013 audi q5. No problems with keyless entry. This is a safety issue if I need to get into my car quickly (e.g. Due to being followed, feeling unsafe in a particular location, nighttime in a dark parking lot, putting kids and groceries in the car, etc.). I have put items down on ground or in cart, unzip purse and get key fob out. Dealer refusing to fix problem because they cannot replicate. Reference the federal safety agency id number: 10945870; 10759256; 10725514

Our mdx has had numerous infotainment issues. The tailgate will open without being present on several occasions. Doors will not unlock on occasion on drivers side with key fob. Wipers will come on without any moisture on various times. Brake warning light will come on while driving without any traffic in front of the vehicle. Rear brakes will hang up and then release while moving slowly.

Power door locks were all defective, became non-responsive to transmitter and driver master switch in year 4. Locks also began cycling open and closed at highway speeds. All 4 actuators had to be replaced over the course of three trips to dealer. I am reporting only the most recent occurrence date as this happened throughout the course of 2017

Tl* the contact owns a 2015 acura mdx. The contact stated that the keyless entry system failed. The contact was unable to unlock the doors if the cell phone and keyless fob were in the same location. The vehicle was taken to the dealer several times. The technician explained that some cell phones might interfere with the keyless system. The manufacturer was made aware of the failure and stated that this was a known problem with the keyless system. However, they were not able to determine what the proper remedy would be for the failure. The failure mileage was 5,000. Updated 11/09/15*lj the consumer stated the front doors would not open. Only rear doors opened, with the tailgate having little minor issues. Updated 1/25/2015 *js
