2017 Acura MDX

As I was driving in a stop and go traffic jam, the vehicle would not go forward although I was pressing on the gas pedal, the engine stall and when it finally reacted after pressing it for the second time it went too fast that I couldn’t stop in time to avoid rear ending the other vehicle, the emergency braking system did not function properly either. This has happened multiple times even when I driven on highways and there’s incoming traffic and the engine goes on stall. But this time it led to an unavoidable accident. I have been concerned for a long time about this issue but I have never received a recall to remedy this problem.

Brake system, Cruise control, lane keeping system get malfunction erratically (ever since 2022, and has been like this), and one of the two sets of brakes never wears off (More than 100 K mileage now (Oct. 2026) , one set of brake pads still is still have sufficient life and does not seem to require replacement. Additiionally, recently (August 2026) the electronic system has gone very bad, the dashboard automatically restarts, headlight turns on, and trying to engaging something, then turned off automatically, then a new cycle starts, and even I turned off again, the cycle will restart until battery is drained and dead, if I do not lock the car (and I had to replace a new battery that was used for less than 1.5 year. If I lock the car, the car will start the same cycle and will honk, and honk, until the surrounding people had to remove the car.

The contact owns a 2017 Acura MDX. The contact stated that while driving, the Adaptive Cruise Control (ACC), brake, and Lane Keeping Assist System (LKAS) warning lights were intermittently illuminated. The contact associated the failure with the brake pads, which had not been replaced since the vehicle was purchased brand new; however, the dealer confirmed that the brake pads were in good condition. Additionally, the contact stated that there were electrical failures after the vehicle was parked. The steering wheel was raised, and the warning light was illuminated while making a continuous clicking sound, and the horn was honking continuously while the vehicle was parked and locked. The electrical failures caused the battery drain and the battery was replaced. The contact stated that several attempts were needed to jumpstart the vehicle. The contact stated that there was an abnormal sound coming from under the hood. The vehicle was taken to the dealer on several occasions; however, the cause of the failures could not be determined. The manufacturer was notified of the failure by phone. The failure mileage was approximately 60,000.

The on board camera mounted on windshield above rear view mirror has failed and now none of the safety feature function (lane keep assist, adaptive cruise, etc).

A lot of lights came on dash, multiple failures of systems listed. Had vehicle scanned, found code U3000-49, forward facing camera issues. Code is hard fault, will not clear. When inspecting camera, found it to be extremely hot(couldn't hold it without getting blistered)

The paint on my roof at the sunroof is peeling in the same exact manner the the already existing Warranty Extension: White Diamond Pearl Paint in Service Bulletin 19-029 or Models 2014-2016, I am aware that this Acura MDX is a 2017 02/17 to be exact and from the same MFG of Alabama that these issues are reported. if you look at the example pictures on the service warranty that are EXACT to the issues with the paint on mine. I have the same paint Color listed as NH603-P and I would like this covered as the year previous model.

When making a slow turn or rolling stop, the vehicle hesitates on light throttle and then experiences a sudden, jerky surge when the pedal is pressed further. This is very unsafe and scary for people around at school crossing and highway crossings

Moisture accumulating within the driver side headlight is limiting illumination and safe night driving. Photos compare driver side to passenger side.

On my 2017 Acura MDX SH-AWD with approximately 112,000 miles, the engine experienced a sudden catastrophic failure while I was traveling at highway speed. The vehicle abruptly lost power, the accelerator became unresponsive, smoke came from the vehicle hood and exhaust area, and multiple warning lights illuminated. The failure occurred with no advance warning and created a serious safety risk because I suddenly lost propulsion while traveling approximately 75 mph in highway traffic. An independent repair facility inspected the vehicle and reported that connecting rod/bearing failure resulted in catastrophic engine damage. I was advised that two connecting rods/bearings failed and caused holes in the engine block, with a rod/component also damaging the A/C compressor. Oil subsequently leaked from the damaged engine. Prior to the sudden failure, I did not have warning lights or other indications suggesting an imminent engine failure. The warning lights appeared during or immediately after the loss of power. The vehicle has been inspected by a repair facility and the engine requires replacement. The vehicle/failed components can be made available for inspection upon request. I am particularly concerned because Acura has previously recalled certain vehicles for connecting rod bearing failures that can result in engine damage, stalling, or loss of motive power. My vehicle is the same model year and has experienced an apparently similar catastrophic connecting rod/bearing failure, but my VIN is not currently included in the recall 23V-751. I am submitting this complaint so NHTSA can evaluate whether the affected population may extend beyond the VINs currently covered in that recall. This is also linked to NHTSA’s new investigation PE25008.

I am filing an official complaint against American Honda Motor Co., Inc. and the local dealership regarding their handling of a mandatory safety recall on my 2017 Acura MDX (VIN: [XXX] / Manufacturer Case # XXX). The manufacturer and dealership are failing to provide a $0-cost remedy for this safety recall by attempting to impose conditional out-of-pocket charges on me: 1. Conditioning Recall Completion on Paid Repairs: The dealership/manufacturer verbally informed me that while the recall procedure itself is covered, I will be required to pay out-of-pocket for any corroded, rusted, or damaged hardware/parts that must be removed or replaced during the disassembly process to complete the recall. They stated that if the vehicle fails their post-repair safety inspection due to these rusted components, I must pay for the new parts before the vehicle is deemed complete/safe. 2. Refusal to Provide Written Estimates: I have repeatedly requested an itemized written estimate detailing these potential charges via email for several weeks, but the manufacturer and dealer have failed to provide one, insisting instead that I bring the vehicle back to the dealership without written terms. 3. Denial of Safe Transportation: The dealership has demanded that I return the vehicle for inspection/repair without guaranteeing a loaner vehicle, while simultaneously stating the vehicle may not pass safety inspection unless I agree to pay for non-covered rusted parts. A safety recall repair mandated by federal law must return the vehicle to a safe condition at zero cost to the owner. Requiring the consumer to pay for rusted components that must be removed solely to execute the recall repair defeats the purpose of the recall remedy. I request that the NHTSA intervene to ensure American Honda Motor Co., Inc. completes the recall repair in full at $0 cost and provides appropriate replacement transportation during the service.

The forward facing camera or monocular attached to the windshield has malfunctioned and is a wide spread issue across multiple models and years. When this item fails due to high heat which causes the camera (CMOS Image sensor) to degrade, the owner is given a slew of warnings and loses a lot of functionality. The dealership quotes an enormous amount of money to replace/calibrate the camera typically between $1500-2500 depending on location. Functionality that is lost includes cruise control, adaptive cruise control, lane departure warning, lane keeping assistance and most importantly adaptive braking. There are also numerous dash lights and repetitive warnings that pop up for each bit of functionality that is broken. So while driving the user will see changing text and hear beeps to inform the driver of these deactivated features which is a major distraction and takes away from the drivers concentration on safe driving. Looking online this issue has been reported by drivers of multiple models and years of both Honda and Acura which means it is wide spread and should be classified as a recall. Just some of the models mentioned are Acura MDX, RDX, TLX, Honda Civic, Accord, CR-V, Ridgeline, Odyssey and potentially others. There is no reason that a camera should fail across all these models spanning over a decade at such high numbers outside of an engineering failure that Honda does not want fork out money for to keep their drivers safe. A couple example part numbers would be 36160-TYS-A02-M1 and 36160-TJB-A040-M1.

I am reporting repeated failures of the front safety camera / Collision Mitigation Braking System (CMBS) on my 2017 Acura MDX Tech (FWD). The vehicle has experienced intermittent and sudden loss of all ADAS safety functions, including CMBS, Lane Keeping Assist, Adaptive Cruise Control, and Road Departure Mitigation. The failures occur without warning, while driving at normal speeds. The dash displays “Safety Support System Problem,” “Collision Mitigation System Problem,” “Lane Keeping Assist Problem,” and related alerts. When this happens, all forward‑facing safety systems shut down, increasing the risk of collision. The issue is persistent and unpredictable. It has occurred in clear weather, dry roads, and normal driving conditions. The vehicle does not have the Advance package or surround‑view system; this is the standard Tech‑package front camera. Multiple Acura service departments have confirmed the problem is caused by a faulty front monocular camera module (part number 36160‑TZ5‑A36). Acura has superseded this part several times (A63, A64, A65, A66), indicating an ongoing design or reliability issue. Replacement cost is extremely high, and the failure disables federally‑relevant safety systems. This is a safety‑critical component. When the camera fails, the vehicle loses collision‑avoidance capability, lane‑keeping assistance, and adaptive cruise control. The failure happens while the vehicle is in motion, creating a risk of rear‑end collisions or lane‑departure accidents. I am requesting NHTSA review this issue for potential defects in the Acura MDX front safety camera system.
