2017 Acura MDX Driver assistance Problems

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 Acura has superseded this part several times (A63, A64, A65, A66), indicating an ongoing design or reliability issue.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.

Problem Description: I am reporting a safety-related issue affecting multiple driver assistance systems on my 2017 Acura MDX. While driving, the vehicle displays several warning messages at the same time, including: Adaptive Cruise Control (ACC) Problem Lane Keeping Assist System (LKAS) Problem Road Departure Mitigation (RDM) System Problem Collision Mitigation Braking System (CMBS) Problem When these warnings appear, all of these safety systems become unavailable. The warning indicators remain on, and the systems do not function even after restarting the vehicle. The 12-volt battery was replaced approximately one month before this issue began, and the engine starts and runs normally. Despite the new battery, the warnings continue to appear, making the vehicle's advanced safety features unusable. This appears to be a widespread issue reported by many owners of the 2017 Acura MDX. Since multiple critical safety systems fail simultaneously, I believe this may be related to a defect in the vehicle's electrical system, charging system, control modules, wiring, or communication network. Because these features are designed to help prevent accidents, their sudden loss creates a significant safety concern. I respectfully request that Acura investigate this issue and consider issuing a recall or extending warranty coverage if a common manufacturing defect is identified.

I am reporting a severe safety defect regarding the sudden, unprovoked failure of the AcuraWatch driver-assist camera system (affecting LKAS, ADAS, and the Collision Mitigation Braking System), which directly and unexpectedly alters the vehicle’s powertrain and driving dynamics without driver input. While driving, the front windshield monocular camera module experienced an internal electronic failure, immediately lighting up multiple critical safety warning indicators on the dashboard and permanently disabling all forward collision prevention and lane-keep capabilities. I urge NHTSA to open a safety defect investigation into 2016–2019 Acura MDX models regarding camera system degradation and its hazardous, cascading impact on transmission shift timing and vehicle deceleration behavior.

Various warning lights appear randomly for collision system, lane departure system and brake system and the radio power glitches on/off while driving on highway. I tested the battery and it's good. At one point I was just about to enter a car wash and the radio power glitched off and then a transmission warning appeared and the car shifted to N and I couldn't shift to Drive. I pushed the P button and the dash just showed a blinking P with the transmission warning. With a whole line of cars behind me for the car wash I was in a panic of course. I turned the car off for about a minute and restarted and was able to get it back to normal but had this issue happened while driving then It would've been dangerous.

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.

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.

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

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.

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.

There were several instances where my vehicle either accelerated or decelerated while I was driving. I first noticed the issue about a week after I purchased the car in May 2022. I took it back to Acura of Brookfield, and they said they couldn’t replicate the issue. I also took my car to Acura of Brookfield in September 2023 for the same jerking issue. They charged me for an update, but the issue did not change. I continued noticing the problem over the years, but it happened more frequently in 2025. In May 2025, I was driving down a hill in Brookfield, Wisconsin, when my car jerked aggressively and then accelerated on its own. Throughout the rest of the year, it would either accelerate or decelerate while I was on the highway. On January 20, while I was on my way to the gym, my car jerked and decelerated while I was on the highway. I was able to pick up speed again and continue driving to the gym. When I came back out, my car started, but it would not shift out of park. I had the car towed to Acura of Brookfield, and they said something about the hydraulics inside the transmission being bad, and that they had to replace the entire transmission.

Hello, I am writing to report that my 2017 vehicle is experiencing the same issue that was subject to a recall on the 2016 models. Despite the recall being associated with the 2016 year, my 2017 vehicle is showing identical symptoms and concerns. This raises serious questions about safety, reliability, and whether this issue extends beyond the originally recalled model year. I would like this concern formally documented and request a review of my vehicle to determine whether it qualifies for repair, inspection, or coverage related to the prior recall. Please advise on the next steps and whether this issue has been reported or addressed for 2017 models. Vehicle details: Year: 2017 I appreciate your prompt attention to this matter and look forward to your response. Sincerely, [XXX] If I get killed me or my [XXX] son, you all will be responsible. You made these faulty vehicles. [XXX] I'm have to get a lawyer involved if issues are not addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dear Acura, My MDX is showing many lights on the dashboard (LKAS, ACC, Break System, CMBS, RDM) associates with the code U3000-49 and all those features are deactivated due to the failure mentioned. I was searching on the website for this error and found many Acura MDX oweners experiencing the same issue which apparently the Windshield Lane Departure Camera. Honestly, Acura should take a look into this since this issue is getting worse and those are safety features on the vehicle. Regards,

My Vehicle intermittently fails to go into "Drive" when pressing the gear shift button. Additionally, various warning messages appear at random, including: Lane Keeping Assist Problem, & Road Departure Mitigation System Problem. I have brought my vehicle to DCH Montclair Acura#709, located at 100 Bloomfield Ave, Verona, NJ 07044, on January 10, 2025, February 18, 2025, and March 13, 2025. Despite these visits and an inspection conducted by my extended warranty provider, the problem continues. On [XXX], while my daughter was a passenger, the vehicle once again failed to shift into drive when pressing the "D" button. This incident, like others before it, occurred without warning and reinforces my growing concern about the safety and reliability of the vehicle. I am now afraid to drive the car, unsure when it might fail again. I respectfully request that Acura take immediate and decisive action to investigate and resolve this issue. If a reliable repair cannot be made, I would like to discuss alternative remedies such as vehicle replacement of buyback under applicable warranties and safety protections

I reported these issues to Acura corporate and to Jackson Acura, dealership I purchased the vehicle from in February 2024. Beginning in July 2024 the vehicle would stall, de-accelerate then the automatic brake would engage, and the vehicle would go into "N" mode, Neutral and lock up. I was able to press the gas pedal a few times, and the vehicle would come back online and drive. This issue happens about every 100 miles driven. On [XXX] the vehicle suddenly de-accelerated, went into auto brake mode and then shifted into neutral. On this date the vehicle locked up suddenly to an abrupt stop, we were almost impacted in the rear with two other vehicles having to take evasive action to avoid hitting us. My wife and I were lucky not to injured by the sudden brake, or transmission lock up. There were no other issues with the vehicle until this date, other than the stall issue. It seems the system had a sudden catastrophic failure. the car has been maintained with oil changes, new battery and transmission service. The car was shutdown then restarted. All the lights on the dash were on and the vehicle was unable to shift to any gear. The vehicle had to be towed to my home address. I was advised to have the vehicle towed to a dealer for diagnostics at my expense. It is currently at Nalley Acura, Marietta, Ga being diagnosed for the issues. The vehicle has 74,000 miles currently. It was purchased with 57,700 miles from Jacson Acura as a certified Acura used vehicle. The Acura dealer and Acura corporate both stated my VIN # was not included in the recalls. It should be included in the recalls as it has the same issues as other Acura models.
