I was driving at about 65mph on the NJ Turnpike at 7:45pm on 8/28/25 when suddenly the accelerator pedal was non-responsive over a period of about 3-5 seconds. The RPMs dropped (engine did not stall) and the vehicle speed began to diminish. No warning lights showed and the dashboard remained lit as usual. The road was wet from a recent downpour. This was a very scary moment as my vehicle was surrounded by trucks. I further depressed the accelerator pedal and was able to regain control of the vehicle. This is the one and only time this happened with this vehicle as far as I am aware. I have scheduled to bring it to Acura service next week regarding this issue. A Google search has revealed several class action lawsuits regarding this issue.

My 2019 Acura MDX which was owned for less than two years, broke down due to a transmission failure. The vehicle had an open recall (one of many recent) delayed by Acura for months, which research shows can cause engine and transmission damage. Acura of Reno denied the recall link and misattributed the failure to “incorrect fluid,” despite admitting the fluid was correct to myself and other businesses. I believe this breakdown was directly related to the open recall and request an investigation into Acura’s handling of these failures. There have been many legal cases against acura regarding this matter previously.

LANE DEPARTURE: WARNING

The windshield camera suddenly failed one day while driving and it ended up disabling all the driver assist systems including the emergency braking, lane keep assist, forward collision, auto high beam, cruise control etc. Over the next few weeks the system kept randomly working and failing during driving every few hours or minutes. The discussion forums are filled with people complaining about the same issue with ALL Honda and Acura vehicles starting 2013 where they camera suddenly fails and then start working intermittently until it eventually fails. It seems Honda is using the same defective camera across all it's Honda and Acura models which is a big safety hazard and they refuse to acknowledge the issue.

FUEL/PROPULSION SYSTEM

My vehicle is showing identical symptoms to those described in recall 21V-215/23V-858 related to the fuel pump. Although my VIN is not listed in the recall, I would like to verify whether my fuel pump is part of the defective batch, as it is failing in the same way (e.g., loss of power, engine shutting off, hard starting when cold, etc.). Or please confirm if my car symptoms are related to different campaigns.

At only 44,318 miles, my 2019 Acura MDX began showing clear transmission problems in the lower gears — including delayed acceleration, gear slipping, and jerky movement when starting or turning at low speed. These symptoms posed an immediate safety risk, especially when merging into traffic or making turns across oncoming vehicles. I first brought the car to Oakland Acura, which incorrectly diagnosed it as a transfer case issue. Their misdiagnosis delayed the repair process and added unnecessary cost and time. I then had the vehicle evaluated at Acura Concord, where it was correctly diagnosed as transmission failure in the lower gears. An independent, certified mechanic also confirmed the same diagnosis. Despite multiple confirmations of premature transmission failure — and a full maintenance history — American Honda offered only a $900 discount on a $9,600 repair, citing the vehicle being just outside the time warranty (but with low mileage well under 50K). I believe this is a manufacturer defect, not a wear-and-tear issue. Safety Concern: This transmission failure is not just inconvenient — it is dangerous. The vehicle hesitates when accelerating from stops or low speeds, which can lead to accidents at intersections, highway merges, or left turns. The misdiagnosis further delayed identifying and addressing this issue. I am filing this complaint to urge NHTSA to investigate whether this is part of a broader pattern with Acura MDX transmissions, and to help prevent similar risks for other drivers and families.

Rear differential SWD light came on was told it was my tires but in fact it is water corrosion in the rear differential oil pump and subframe wiring harness. Acura is aware of the issue but will not warranty the work. This should be a recall

LANE DEPARTURE: WARNING

Vehicle Make/Model/Year: 2019 Acura MDX Component Affected: Forward Collision Avoidance / Lane Departure / ADAS (Front Camera System) Summary of Issue: I am filing this complaint regarding a recurring and dangerous issue involving the front windshield-mounted camera on our 2019 Acura MDX. After purchasing this vehicle and driving approximately 5500 miles in Las Vegas, multiple critical safety warnings began appearing on the dashboard, including: •“Collision Mitigation System Problem” •“Road Departure Mitigation System Problem” •“Lane Keeping Assist Problem” •“Adaptive Cruise Control Problem” These warnings occur continuosly. The warning lights won’t turn off, resulting in the complete shutdown of essential Advanced Driver Assistance Systems (ADAS). Safety Concerns: This camera-related failure disables major safety features designed to prevent accidents. The driver is left without automatic emergency braking, lane keeping, or adaptive cruise control. This is especially dangerous at highway speeds. Acura has not issued a recall, despite the widespread nature of this problem and documented cases in other hot-weather regions. Service Experience: We purchased the vehicle used from a Cadillac dealership. The issue began approximately 3 months after purchase. A mechanic confirmed that the front camera system is likely malfunctioning due to heat exposure—a known problem with this model. Why I’m Reporting: I believe this is a safety defect that should prompt investigation. Acura appears to have issued Technical Service Bulletins (TSBs) but has not taken action to proactively notify owners or issue a recall. This defect compromises driver and passenger safety and puts others at risk.

The passenger windshield behind the driver's seat smelled of smoke and exploded the car while driving. This model has had multiple of the same problem with other cars and refused to identify and fix the problem. I have been informed by Acura that it's an out-of-pocket expense and not covered by warranty because it's not yet under recall despite several occurrences.

EXTERIOR LIGHTING

The headlight assemblies to my vehicle have become defective. The headlight assembly, both right and left, has moisture intrusion within the headlight assembly, creating condensation build-up inside the housing. This issue also caused the headlights to become white and hazy in appearance. I was advised by the dealer that this would lead to failure with the lighting and would have to be replaced. I purchased a certified used vehicle with Tustin Acura in August of 2022 and also purchased an extended warranty for piece of mind. In the 2 1/2 years that I have owned the vehicle, I have added about 25k miles and have always garaged the vehicle. When the issue was reviewed by the dealer, they refused to cover the problem under warranty and requested that I reach out to American Honda for further assistance. I did that but was denied and told the issue was caused by "outside influence," but provided no explanation as to what this meant. To me it felt like I was being blamed for clearly a defective issue. A Google search of this issues revealed to me that this was a common issue with 2019 Acura MDX vehicles. To replace the headlights would be a cost to me of nearly $3,000. it seems almost ridiculous to pay for clearly defective equipment. I fear that my inability to afford this great expense with lead to headlight failure that could result in a collision if this failure were to occur at night.

My 2019 Acura MDX with 100K miles stalled on the road with several alerts on the dashboard and went into Parking mode with no further movement. Had several alerts stating Transmission failure, Blind Spot monitoring failure, Auto break system failure and vehicle stalled on the road. Had similar issues previously where the steering jammed and vehicle was stalled on the signal, took it to Acura dealer and they had to fix some circuit / reset the circuit board. Was ok for few months and last week the car stalled with Parking sign on. Towed the car to the Dealer service center, they diagnosed and identified there is a failure with transmission. They quoted around 10000 dollars for replace new and 7000 for used transmission. This is huge money, hence called Acura customer care for any review/support but they claimed this issue is not in their current recalls or claims, so cannot support. had to pay out of the pocket. Per google there seemed to be a lawsuit with Transmission failures with Acura 2019 mdx vehicle. Acura customer relations is asking to get into the law suit group and Acura as such cannot help the customers with these problems. Had Lexus for several years with no issues and very upset/annoyed with these type of repairs within 100K / 5year old.
