ENGINE
My vehicles motor is internally destroying itself. The rod bearing has gone and the motor is none functional. The car only has 98k miles. I have gotten the oil changed every 3k-4k miles and used 0W-20 oil as the manufacturer desired. It seems as though there has been 1.4million cars with this same issue as mine. I think a recall is in order. OEM new motor is $25.7k.

SERVICE BRAKES
Asymmetrical wear on the front brakes. The outer pad wears out completely while the inner pad( with the brake wear sensor) shows almost no wear. The dealer (Park Place Acura, Plano Texas) brought this to my attention on November 3, 2025 saying only the front pads needed replacing but did not disclose the asymmetrical wear. I took the vehicle back to the Dealer January 15, 2026 for repair after discovering the asymmetrical pad wear and pointed that out to them. The brakes can completely wear to the backing plate on the outer pad while showing no wear issues with the brake sensor on the inner pad. This condition creates an unpredictable and uneven braking response that constitutes a safety defect, as the brake wear indicator system fails to alert the driver to actual brake wear on the outer pad. The brake wear sensor is designed assuming symmetrical pad wear. When wear is asymmetrical, the sensor fails to trigger a warning, leaving the driver unaware of a dangerous condition. The dealer has finally replaced the pads and rotors, symptoms of the problem but, has not addressed the underlying cause of the problem...the calipers. I have received the vehicle back from the dealer but did not sign a release and the issue remains open. The vehicle currently has approximately 29,400 miles. I have taken this issue to Acura corporate(Honda Motor Company) and they have it under review but keep delaying with no confirmed resolution. I sent a certified letter to American Honda Motor Company, Acura client relations on February 3, 2026 and they signed for it on February 11, 2026 and contacted me by email on March 11,2026. Acura took 28 days to respond to my certified letter and has provided no resolution timeline since.The vehicle was under the original manufacturers warranty at the time of this issue and notification.

FUEL/PROPULSION SYSTEM
When I have already started to go in motion, for example when turning left, and I let go of the gas pedal and then press the gas again once I decide its safe to turn, my car doesn't respond to the gas for about a couple of seconds. This has also happened when I am driving on the highway and I am already in motion and I want to go faster to pass another vehicle, my car hesitates for a couple of seconds before it responds to me pushing the gas pedal.

ENGINE
The motor through a misfire code and began making a noise while vehicle was sitting at a red light. Vehicle lost all power and had to be towed. Was quoted my the Acura dealership $9k. Main reason for addressing this concern is because numerous Acura J35 series motors have already been recalled for engine connecting rod issues. While this motor doesn't apparently fall under that recall, odd that it would essentially had the same issue, when it only had 136k miles and has been maintained to factory standards (or better)

EXTERIOR LIGHTING
I saw previous warning when I pulled my credit report on Experian, but I am not seeing any recalls currently. My driver side taillight is malfunctioning. It appears there is a problem with the seal which is allowing water to get inside the assembly, causing it to short out. I realize this vehicle is a 2015 but thought I would mention in case this is still an issue under recall.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING
I am reporting a major safety failure on my 2017 Acura MDX regarding the forward-facing multipurpose camera. Out of nowhere, the camera failed and triggered a cascade of warning lights across my entire dashboard. Because of this hardware defect, all of the critical safety systems—including the Collision Mitigation Braking System (CMBS), Lane Keeping Assist (LKAS), and Adaptive Cruise Control—are now completely disabled. Having these emergency systems shut down while driving in traffic is a serious safety hazard. Furthermore, the constant flashing of 5 or 6 different warning lights on the dash is a massive distraction while trying to operate the vehicle. This is a well-documented hardware failure in these models, and it shouldn't be left to the owners to pay thousands of dollars to fix a primary safety component that failed prematurely. This needs to be investigated as a mandatory safety recall before these failures lead to an accident.

POWER TRAIN
The component that malfunctioned was the transfer case, the vehicle was already repaired so an inspection isn't possible anymore. The vehicle behaved as normal until the accelerator was pressed enough to make the front wheels lose traction, in which the vehicle couldn't send power to the rear, because the transfer case was shredded up. When needing to accelerate quickly in traffic, the vehicle would completely spin up the front tires, not being able to put the power down. The dealer reproduced the problem, but initially stated that it was most likely due to the salt on the road (it was winter). As spring arrived, the problem still persisted, in which the dealer checked the transfer case and found it was shredded. They replaced the transmission and transfer case under warranty. There were no warning lights, but accelerating quickly would cause the car to spin up the front tires uncontrollably. In corners, this meant severe understeer that could be dangerous in the wrong circumstances.

Hello… this has happened at least four times.. the car goes to stand by/idle mode when the auto shut off is engaged. I was at a light and car went to idle and when it goes to green. Car just goes to idle mode. I had to put hazards on and restart car. People honking while I’m trying to restart car from this state. It’s like the car does not return on after the gas is engaged.

When the auto start stop engages my car will shut down and then it takes a minute or two for it to restart. This has happened several times. I reported it to Acura previously and no action was taken. It’s difficult to replicate because it doesn’t happen every time. It’s unsafe and scary because it will happen at stop signs, or in traffic and with my children in the car. It just happened about 5 mins ago while in traffic and I remembered to report this.

Auto start/stop system - yes, it is available for inspection. The vehicle turned off at a buy intersection and it was a couple of minutes before it would restart. The vehicle will be inspected my a dealer on Monday. No manufacturer, police, insurance representative has inspected the vehicle. There was a message when the vehicle turned off but I can't recall what it said as other drivers were blowing horns and I was focused on my safety at the time.

My vehicle stopped handling as it usually had and I at a significant decrease in traction and slid off the road and slammed into a road sign. No injuries but significant damage to the vehicle. It seemed as though the all-wheel drive was not working. No warning lamps and computer system indicated that all four wheels were getting power. Took it to dealer and they confirmed that the all-wheel drive system has failed. Splines in the transfer case stripped and transmission needs to be replaced

Customer reports: - vehicle will not start - died while backing up and wouldn't restart - no warning in car and safety at risk as a result - towed car to auto mechanic who provided this information below Check and advise: - Found starter motor tries to crank the engine over but never completes more than a partial engine revolution during each starting attempt, using jumper packs do not help, fully charged and tested battery and found battery tests bad, installed tester battery for diagnostic purposes and found engine still wont crank, attempted to rotate engine via crank pulley bolt and pry bar and found engine will not rotate indicating engine is seized due to some sort of internal engine issue, suspect possible connecting rod bearing failure but cannot confirm without significant engine disassembly. - This issue (apparently its a widely known problem on this engine and there is an active recall campaign developing): Acura MDX 2016 has a recall but my VIN # is not showing up in it. However, I strongly believe it is the same issue and Acura should expand their recall to include more vehicles, including my own.

SUSPENSION, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. There was no prior warning of water intrusion or external damage that would reasonably explain this level of corrosion. This appears to be a premature failure of a critical electrical component. Acura has only offered minimal goodwill assistance, leaving the majority of this extremely costly repair as the responsibility of the owner. I am concerned that this may be a broader issue affecting other vehicles and that it could pose a safety risk if not addressed. I am requesting that this issue be investigated. Thank you.

SUSPENSION
A little over one year after purchase, I began receiving dashboard warnings related to the air suspension and braking systems. I scheduled service with the selling dealer (located over two hours from my home). By the time of my appointment, the rear of the vehicle was visibly unstable and bouncing during operation. Upon arrival at the dealership, while the technician was driving the vehicle into the service bay, the rear air suspension bag exploded. Once the vehicle was raised on the lift, the opposite rear suspension bag also exploded. I was informed by dealership personnel that had this occurred while I was driving – regardless of speed – it could likely have resulted in a crash. The stated cause of failure was severely corroded rear stroke sensors. Including that incident, I have had a total of 5 corroded stroke sensors replaced within an approximately one-year time frame. This appears to be a recurring and systemic defect rather than isolated component failure. The repeated corrosion of critical suspension components in a nearly new vehicle raises serious concerns about moisture intrusion, improper sealing, or design defect affecting safety-critical systems. This issue creates a significant risk of sudden suspension failure, loss of vehicle control, and potential crash. I am concerned that other owners may experience similar dangerous failures without warning.The vehicle has been serviced only at an authorized Acura dealership, and all repairs are documented. Exact dates of each repair: 4/10/25 – Both rear stroke sensors (mileage: 13,632), 9/24/25 – Left rear, 2/6/26 – Right front, 3/20/26 – Left rear, Current mileage: 25,160

SUSPENSION, UNKNOWN OR OTHER
MDX Type S with 63k miles. After performing diagnostic check there were several fault codes related to the vehicle's suspension system. Upon inspection, they identified issues with the ride height (stroke) sensors and wiring. The right rear, left rear, and right front sensors are affected. The right rear sensor has a broken pin, and part of that pin is stuck in the wiring connector. The left rear sensor also has a pin that is corroded. Additionally, the main wiring harness along the floor is corroded. This is due to poor location of wire harness in the Type S, and corrosion was due to salt exposure from icy roads. Dealership confirmed this was a known issue and had about a dozen of these replacements in the last few months.
