2017 Acura MDX driver assistance complaints
Page 2 of 3: complaints 11 to 40 of 44, newest first, as owners wrote them.
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 the federal safety agency 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.
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,
Automatic transmission. The car does not go to park when selecting park, it goes into neutral mode. It does not park at all.
Blind spot warning, forward collision warning, lane departure warning, lane keep assistance, and high beam lights keep flashing on dash giving a code of: U3000-49. The dealership quoted me $2000 to fix a faulty front facing camera. Research shows this is happening to thousands of people.
The LKAS and Parking systems will randomly decide to cease functioning and express error messages. The car has not been in an accident.
the camera keep going online/offline in a middle of a highway while I'm on cruise control LKAS, ACC, Camera, and ect warning lights keep coming on.
The front lane assist camera has failed internally and now the lane assist, forward collision and adaptive cruise control no longer work. This has been a known issue and has happened to other Acura MDXs. The warning lights are now coming on saying the vehicle had a brake system error. It also states that all systems related to this camera are inoperable.
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
There are warning lights for all safety modules, The LKAS, Headlight warning system accident prevention system, collision avoidance system etc..
There is an active recall on the brake calipers and fuel pump for Acura Mdx 2017, and Hondas. My Acura Mdx 2017 has the same issues with a code of p07e4, which is the brake calipers. When looking up the recall of my car, there is no recall on it when inserting the VIN. My car is an Acura Mdx 2017; I do not understand why it is not included in the recall when it should.
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.

I bought the vehicle in february 2024 from a certified acuara dealer. On december 26th the vehcile suddenly went into neutral mode and would not change into any other gear. The car was shutdown and restarted about 5 minutes later with the dashboard full of warning lamps at start up. I attempted to move the car from the roadway but the gear shift control would not work in any gear. Transmission warning lamp came on. The car was towed back to my home address. This car was acura certied used. It has been maintaind by a honda service center. Acura, honda and the acura dealer locally all have stated there are no issues with the car or warranties for the issues. The car has 74582 miles. Based on online forums this seems to be an issue with many acura mdx owners. Acura and honda america are not acepting their product is defective. Lastly, we nearly avoided being in a severe accident due to the sudden stop on the roadway
On highway and switching lanes. All of a sudden ELECTRIC PARKING BRAKE AND ALL DRIVER ASSIST LIGHTS CAME ON. Pull over light came on as well. HIT ON LEFT REAR SYMBOL CAME ON. Was never hit just a close car on driver left rear side when switching lanes. Made it home and vehicle wouldn’t switch back into drive mode. Acura didn’t do its due process and assumed a new transmission was needed. Replaced and a month later ELECTRIC PARKING BRAKE sign starts flashing again. Now dealership is saying I need a new catalytic converter. Refused as I believe Acura has been incorrect about the diagnostic. They also stated my vehicle was in a collision and it wasn’t. They refused to check electrical issues and update software as these things are not in my control. It is my belief the car had a faulty collision warning which is causing other issues as well as Acura refusing to probably assist and diagnose without me continuing to be falsely diagnosed
I have a 2017 Acura MDX that had around 98k while I was driving down the highway at 65 mph all lights came on the dash and lost acceleration would not go over 45 MPH on a very busy highway. Had to have the vehicle towed per dealership- towed to Jay Wolfe Acura, Overland Park, KS. They said engine needed to be replaced due to the miss fire of rod knocking. There was no other option for replacing the rods had to replace the engine. In addition they replaced with an used engine that is a 2016 not even the same year. Dealer made us aware of the recall for this issue but advised us the Vin# is not under the recall so we had to pay out of pocket. I have tried to work with Honda and the dealership for reimbursement since there have been numerous vehicles with this exact issue but the Vin#'s not under the recall but with no help at all. I have provided documentation and explained the issues and the repairs. I have documentation but was not able to add it to the document listing below
Driving in rain and multiple systems failed at once without any reason. Car indicates brake systems, lane assistance, power steering, collision mitigation, stability control, etc all indicate problems. No reason for it to all go out at once.
I had the transmission system failure error came on the dash and the car wouldn’t drive to D or reverse then blind spot and adaptive cruise control error propped up
Driving down the freeway cruising around 70 miles per hour when the multiple sensors tripped and car started to slow down to 50 mph. Took the exit and when I came to a stop the car was moving very slow. Had to go over an overpass and it barely made it over. Close to home so drove the car slowly. The car at times would stop moving and took a little time for it to pick up and started moving slowly again. The sensors that showed were the electric parking brake problem, emissions system problem, transmission system problem, blind spot info system problem. Had I not been close to home or no exit near, my car would have kept slowing down on the freeway. Family car and I also had my kids with me.
My car routinely sends a warning alert that there is an approaching object. It happens more frequently, when the temperature is hot, and it happens mostly when I am stopped at a traffic light. Occasionally, the alerts continue as I'm moving, which is really distracting, but even sitting at a traffic light is distracting and creating a safety issue. I listed yesterday's date, but this happens nearly every day that I drive this vehicle.
This morning I read that you were investigating the automatic braking for certain Honda models. I have had this same thing happen with my 2017 Acura MDX several times over the past few years. I would be driving (not following another car), and my car would suddenly brake and flash "Brake" on the screen, without my doing anything. Both times, I attributed the issue to driving into a bright sun, but I am not sure. It did not cause an accident and it was not a big deal, but the last time (about 3 months ago) I remember braking and being nervous about someone else read ending me...when I tried to accelerate I was unable to do so.
Cruise control set to 37 mph, vehicle accelerates to almost 50 mph on downhill without braking.
On multiple occasions (6 times within a week) the powertrain loses power. While traveling 60 mph in 4 lane Interstate traffic engine loses all power and accelerator ceases to respond. Passengers were at risk due to no power. Acura Dealer has not been able reproduce. Some dealers have affirmed that they've had customers with the issue but can't reproduce. The issue seems to occur more frequently after cruise control has been dis-engaged. I have spoken with another a 2018 Acura owner directly and they have experienced the same issue. It does seem the engine/powertrain resolves when the transmission is switched from "Normal" to "Sport" mode. The amount of time with loss of power seems to span about 5-10 seconds.
Driving East on Interstate 20/59 10 miles East of Meridian, MS November 17, 2021 around 2:00 PM. A lot of trucks on the road. Had speed control set at 69 MPH. Came up behind a semi doing about 65, pulled over to the left lane to go around him. When I got about half way all of a sudden all hell breaks loose. Vehicle goes in into emergency stop with lights flashing all over the dash. Vehicle brakes to around 30 MPH within a couple of hundred feet with semi's and cars beside and behind me. Finally got the vehicle over to the side of the rode without and accident. (A miracle inself). Code DTC P0716. After about an hour of shutdown, started engine and all messages were gone. Took it to the Acura dealer and they, evidently, updated the TCM software. I had not been notified that it needed and update which is negligence on Acura. This incidence could have been a catastrophe with possible deaths. Now my wife is really afraid to drive this vehicle.
2017 Acura MDX purchased May 2020. Incidences has happened 5 times. Twice this month in July 2021 the brakes engaged! Anxiety and fear of being hit by cars behind. 1st incident:location back road When the brakes engaged the vehicle in front had taken a right turn. The vehicle was cleared from mine so it came as a scare as it stopped in the middle of the road with others behind me honking….. The brakes released and i proceeded driving. 2nd:location back road Again In front a vehicle turned right and the brakes engaged. I hit the gas gently i dont know if that helped to disengage the brakes or not. 3rd: location highway Brakes engaged and immediately released. I was in passing lane and a truck in middle lane ….. this made no sense. 4th: location at intersection Truck turned left across and in front of me, brakes engaged and stopped my car, only to find out a low trailer was being towed. Brakes did help prevent an accident. KUDOS earned here!!!! 5th: location back road speed less than 40mph Vehicle in front of me turning right Again my brakes engaged! Again I used the gas hoping the brakes would disengage. I dont know if it helped or not. Now I ONLY use the cruise control on highways.
While driving on normal road with no other cars around, the emergency braking system/forward collision activated and immediately stopped my car with no danger present. This resulted in the car behind me swerve to avoid hitting me in the rear. No warning lights were on the dash or no audible warning either. This seems to be a malfunction in the system.
