ENGINE
My 2017 Acura MDX had a complete engine failure because of know critical rod bearing issue which hasn’t been extended to all 2017 models of the MDX. My engine completely failed when I was entering a roundabout and nearly caused the car behind me to rear end me then left me dangerously stranded in the roundabout. Even though this is a known issue for this year, make and model of my vehicle Acura said it was my fault without asking for detailed maintenance records and said this recall only applies to certain vehicles produced. I had to pay $7995.71 for a new engine and this issue needs to be addressed before someone is killed. Thank you

FUEL/PROPULSION SYSTEM
When accelerating into traffic (usually merging onto highway or changing lanes on the highway) my car will loose all power and fail to accelerate. This is extremely dangerous and has happened on several occasions. I have taken this into Acura as well as other automotive dealers and no one can seem to diagnose or recreate the problem. The only support I received from Acura has been a “software update & idle relearn”, which has never fixed the problem. I saw an NHTSA ID#23V85800 recall alert for Fuel Pump Failure, which perfectly describes the issues I’m having. Unfortunately, my VIN is not included in this recall. I respectfully request that you add my VIN to this recall so I can get my fuel pump replaced and hopefully resolve this very dangerous issue.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving my LKAS, ABS, and Lane assist lights will come on intermittently. When this happens I am not able to use cruise control. I have noticed that my vehicle has an issue accelerating before the lights come on. This is putting the safety of me and passengers at risk. The dealership has not been able to replicate the issue. The dealership and independent mechanics are not able to figure out what is causing the issue. I have spent close to $4,000 trying to figure out what the cause is, and nothing is showing up.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving on the interstate over 2 hours from home the car put itself into neutral and almost caused us to get into a collision. While accelerating after a construction zone, the lights on the dash of the vehicle lit up with transmission, emissions, electronic parking brake, and more codes. The car shifted itself into neutral while running between 65-70 mph on the interstate. Multiple vehicles were accelerating after the 55 mph work zone area was over, and we had to swerve between cars to get to the shoulder of the road because the vehicle lost all acceleration capabilities. We have taken the vehicle to the dealer for past recalls and software updates and mentioned this issue happening before and were told that the vehicle showed no codes concerning the electronic parking brake issue. Upon further investigation, there are multiple reports and forums of this particular vehicle having the same issue. Its a miracle we didn't get involved in a massive collision with semi trucks and other vehicles amongst us when the vehicle lost all ability to accelerate. This could cause a huge problem if it were to happen again in a more populated area or at increased speeds. We were stuck on the side of the road for 4 hours waiting on a flatbed to tow it because it locks up the AWD system with the electronic parking brake and doesn't allow the wheels to move. This is the second time we've had it towed for this same issue only to be told that it's not a problem. I'm willing to bet that the company knows exactly what the issue is but won't issue a recall because they don't classify it as a safety recall until people start losing their lives or cost the company stockholders money. This problem has the ability to cause major harm or death to people with this vehicle if it were to shift itself into neutral or lock up the electronic parking brake while in a heavy populated area. I hope they issue a safety recall and hold the company accountable before people lose their life.

STRUCTURE:BODY
The paint on the roof between the sunroof and front windshield is peeling. I took it to local dealership and was told paint is covered under Acura's Rust Perforation Limited warranty which is 5 years from the of original purchase. I do not have an extended warranty so I would need to pay out of pocket. I believe the classification of this issue under the "Rust Perforation Limited Warranty" is incorrect. The issue is not corrosion originating from the inside out. This is a premature failure of the paint adhesion to the primer, which is a manufacturing defect. This is a known, widespread issue affecting Acura's White Diamond Pearl paint, which is the subject of a pending class action lawsuit (Case 2:24-cv-09728) alleging these paint defects exist in 2013-present models.

TIRES:TREAD/BELT
Continental Cross Contact LX Sport 245 / 50 R 20 102 H tires. We had them installed at the Acura dealership on 7/14/2023. We noticed recently the tire tread on the front driver side in an area was peeling up in a small spot. At our oil change and tire rotation with Acura on 4/24/26, I notified them and they stated tire was okay. The tires currently only have about 15;389 miles on them. I contacted Continental Tire because I noticed the tread peeling or pitting on both tires that were rotated to the rear getting worse. Continental told me I could take to a tire center that sells Continental tires to have them inspected. Took to Discount Tire and they submitted information to Continental Tire. They responded with a prorated amount of $230.00 total for the 2 rear tires only. The rep with Discount Tires informed me that all 4 of my tires came from the same manufacturing plant and same lot. I am concerned that my front tires will start to peel or pit like the other 2 tires. We have maintained regular tire rotations and maintenance on our vehicle. We also do not drive on gravel or dirt roads or aggressively and the vehicle is kept in our garage. I am now looking at having to replace all the tires because I am concerned about driving with the tires in their current condition. This is concerning to me because tires should last longer than 15, 389 miles.

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
The multipurpose front camera on my 2017 Acura MDX failed with DTC U3000‑49, disabling LKAS, ACC, CMBS, and FCW. Acura issued Service Bulletin 23‑008 acknowledging a software defect, but my VIN was denied eligibility despite matching the bulletin’s criteria. This is a safety‑critical failure affecting many owners, and Acura is forcing consumers to pay for camera replacement instead of providing the software fix. My 2017 Acura MDX (VIN [XXX] ) is experiencing a failure of the multipurpose front camera, which controls several collision‑avoidance systems including: Lane Keeping Assist System (LKAS) Adaptive Cruise Control (ACC) Collision Mitigation Braking System (CMBS) Forward Collision Warning (FCW) All of these systems became disabled, and the vehicle displays multiple warning lights. The diagnostic code stored is U3000‑49 (FCW/LDW Camera Unit Malfunction). Acura issued Service Bulletin 23‑008, which states that: “A problem exists with the detection logic in the multipurpose camera software.” The bulletin applies to all 2017–2018 Acura MDX trims, and the corrective action is a software update to the camera module. My vehicle matches the exact symptoms described in the bulletin. However, Acura and the dealership informed me that my VIN is “not eligible” for the update, even though the bulletin explicitly lists my model year and trim. Instead, I was told I must pay for a full camera replacement, costing over $1,200, despite Acura acknowledging the issue is software‑related. This leaves me with a disabled safety system and no manufacturer‑supported remedy. The failure is widespread among 2017 MDX owners, and many report identical symptoms and identical denials of coverage. Because this defect disables multiple federally relevant safety systems simultaneously, I believe this should be treated as a safety recall, not a customer‑paid repair. I am requesting that NHTSA investigate this issue and require Acura to provide the software update.Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

ENGINE
A rod bearing inside the engine failed and created metal shavings inside the engine. The vehicle has not been fixed yet, so it is available for inspection currently, but I will be having the engine replaced in the next 2 weeks. With the metal shavings inside the engine it could cause a catastrophic failure of the engine while driving at any point The dealer has inspected and diagnose it as a rod bearing failure I reached out to Acura customer service to make them aware and ask for assistance in reviewing for coverage in the ongoing recall, but since my vehicle was not manufactured in the plant covered under the recall, they are unable to help. I asked for a good will credit and after they conferred with the dealer they stated the failure was not due to a manufacturing defect, therefore they cannot help. There were no warning lamps or messages from the vehicle. The only symptom was a ticking sound, that got louder at higher RPMs, coming from the front of the engine on the passenger side. I’ll also add that based on CARFAX report and our service records since we bought the vehicle, all recommended maintenance has been performed as recommended by the manufacturer.

UNKNOWN OR OTHER, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My 2017 Acura MDX unexpectedly shifts into neutral while I am driving, specifically when slowing down approaching stop signs. When this happens, the vehicle loses power and will not accelerate, creating a dangerous situation in traffic. I have to manually press the Drive button to put the vehicle back into gear while still on the road. This has happened multiple times without warning and no recall exists for this issue. This is a serious safety hazard because the vehicle can lose power in traffic or intersections.

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.

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.

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.

AIR BAGS, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
On 11.25.25, my MDX was involved in a multi-car hit and run on highway 101 SB at the Laurel Drive off ramp. The vehicle sustained two points of impact: (1) substantial front/driver side impact (2) rear-passenger side impact. Despite the severity, location of impact and speed of travel at the time of the collision, all airbags deployed except for the driver side curtain airbag. Importantly, at the time of the crash, the Lane Keeping Assist System (LKAS) and associated AcuraWatch driver assist systems were activated. The vehicle’s safety assistance technology was engaged and functioning immediately prior to impact. Considering the above mentioned facts, driver side airbag failing to deploy, raises serious concerns regarding Possible software or signal-processing malfunction or electronic communication between radar/camera systems and the SRS module. The nature and severity of the impact clearly met deployment criteria for the driver side airbag. This failure raises concern that there may be a defect in the SRS system, including but not limited to: Airbag inflator component or propellant issue. Supplemental Restraint System (SRS) crash sensor calibration. SRS control module deployment logic. Crash signal sensors. Event-trigger logic or interconnnect failure. Wiring harness or inflator defect. Whether the system registered steering correction or impact prediction, the failure to deploy increased my risk and resulting injury, as well as compromised the fundamental safety system designed to protect drivers in front-impact crashes.
