2017 ACURA MDX Safety Overview

Component: SEAT BELTS

"The contact owns a 2017 Acura MDX. The contact stated that the second-row passenger’s side seat belt became stuck and failed to retract as needed, causing the seat belt to become inoperable. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was provided. The failure mileage was approximately 200,000."

Component: ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE

"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 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."

"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."

"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."

"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."

"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."

Component: 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."

"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."

"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."

"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."

"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."

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.

"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."

"My 2017 Acura MDX has an engine failure due to connecting rod bearing seizure in the 3.5L V6 engine. Recall 23V-751 covered model year 2016-2020 Acura MDX vehicles and mine is a 2017. But, my VIN is not in Honda's recall range. The ODI had apparently received 414 reports of connecting rod bearing failures in the 3.5L V6 engine that are outside of 23V-751. There is now an ODI Resume with number PE25008. See the two linked PDF documents below. [XXX] [XXX] The Acura dealer said that this is definitely the same problem they have seen on vehicles under the recall range. In their computer system where it says "Cause" they wrote "Cylinder 6 spun causing the knocking noise. excessive material in oil pan. if under the rod recall, it would need a long block." I have a screenshot of this if you would like it. My service representative at the dealership texted me the following "The engineer from Acura was here today and our District Manager - the engineer said they will not be expanding the recall on the Acura side. Just thought I'd let you know." I have this text message if you would like a screenshot of it. So, it sounds like Acura will not voluntarily expand the recall. This is going to cost me about $12K to fix. Is the NHTSA ODI investigation still ongoing? When will I know if the VIN range will be expanded as I would like to get reimbursed by Acura for these repairs.

My brake would not work, I tried putting car in park to stop it moving. It proceeded to ram into the semi in front of me and keep trying to go forward until the light turned green and the semi drove away at that point I was able to drive my car and pull off the road and my brake began to work when I pulled off. It completely stopped working when I was on a busy road and caused the accident. It could have been much worse if I was not stopped already."

"The contact owns a 2017 Acura MDX. The contact stated that the dealer recommended that the timing belt be replaced. After the timing belt was replaced, there was a ticking sound coming from the vehicle while being started. The sound occurred while driving at various speeds or while the vehicle was idling. The check engine warning light was illuminated while driving approximately 60 MPH. The contact pulled over, turned off, and restarted the vehicle, and the warning light was no longer illuminated. The vehicle was returned to the dealer, who diagnosed that the short block, bearings, and the oil pan needed to be replaced. The dealer recommended that the engine needed to be replaced. The vehicle was not repaired. The contact learned of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling); however, the VIN was not included.

"I was driving my vehicle on the highway at 65 MPH when the engine light came on and began blinking- no other issues. I tried to pass a vehicle, and my vehicle would not accelerate, I was less than a mile from work. I called the dealership the same day and was able to take it in. When I called, I explained everything the dealership told me I could either tow it or try to drive it in. I went out to the car later and moved it from one parking lot to another and had no issues and no lights came on alerting something was wrong. Later in the day as I was driving 65 mph again on interstate, just as I was slowing down to get off all of the lights for everything came on and the engine was making a terrible knocking sound. I slowly pulled over and put my hazards on while driving 15/20 mph. I was near the dealership and was able to coast into the repair shop. Was informed the engine needed to be replaced due to a misfire on cylinder 2 and rod knock- most likely rod bearings and crank shaft issue with broken rod. We have an extended warranty so for a used engine found at a salvage yard won't cost much out of pocket with a similar amount of miles. Used engine will have 12K mile warranty/12months.

"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,"

"On my way home from work one evening, the car started making a loud knocking noise, then the car started losing power, the rpms jumping up and down and the dashboard lit up with warnings of all kinds. The traffic was somewhat heavy and and cars were speeding pass me, brakes screeching, horns blowing and my car steadily losing power. I was afraid, I didn't know what to do. I was trying to find a safe place to pull off the road. It was a traumatic experience as a large truck swerved into the other lane of traffic to avoid hitting me, almost causing an accident. Luckily I made it home safely. I had a mechanic look at it the next day and he said the engine needed to be replaced. Not convinced of the diagnosis, I had the car towed to another mechanic who confirmed the engine would have to be replaced. I had no issues with the car or the mechanics of the car prior to this. I could not for the life of me understand how my 2017 Acura MDX with only 74,000 miles on it, could possibly need a new engine unless it was defective. So I then towed the car to the Acura dealership where they confirmed, the engine needed to be replaced. However, when I asked about the engine recall, I was told my VIN is not included in the recall although it is the same exact issue. Acura did offer a one time goodwill assistance for 25% of the repair costs if performed at Acura. Admission of guilt knowing my car has a defective engine is what that says to me about Acura's offer of 25%! Since the car was useless without a engine, I have since had it repaired by an independent mechanic. I'm very disappointed in Acura."

"My 2017 Acura MDX with only 87,000 miles has suffered catastrophic engine failure. The vehicle has been properly maintained and all repairs recommended by the dealership where the performed since it was purchased new. While the dealership has confirmed the engine failure cause is exactly what is feared by the Recall Report 23V-751, Honda has refused to acknowledge their responsibility since my VIN does not fall within their "identified" inventory. The engine is currently at the dealership and will be maintained as evidence for the "to-be-filed" lawsuit that will be required to recover the repair costs. The engine seized while driving and had to maneuver the vehicle to a safe location. Had I been travelling on the highway at the time. the outcome would have been disastrous. The problem is described in detail in Recall Report 23V-251. There were no warning lights or issues other than a clunking sound the night before. I was driving to the dealership at the time the engine failure occurred."
