My fiancé is 8 months pregnant and her sunroof literally exploded on her while she was on the freeway yesterday. She was almost in an accident and could have been killed. She has a 2020 MDX and I’m reading online that she isn’t the only person this has happened to. The dealership told her that she’s on her own and this defect isn’t covered under warranty when she called. It has not been inspected, but I have taken many pictures. There were no warnings or indications anything was wrong.

Car will not restart from the Auto Idle Stop when at a stop light. The dash goes blank then flashes everything and it takes a minute or so to restart. It has happened 3-4 times in the last 6 months. Once on a 55 mph highway. Very dangerous safety issue. I have take it to the Acura dealership service department and they say diagnostics does not show why. However, They said it has happened to their TXL model and a software update was the solution and they are hopeful they will get on update soon. Service associate did say others have been calling in about the same issue. But do not know if Acura is working on a fix. I did report the incidents to the national Acura customer service department and have a case number.

Periodically when accelerating the car (2020 Acura MDX) looses power. The car does not stall it just looses power. There have been times when we have had to pull over to avoid causing an accident. When it does occur there are no warning or signal displayed on the dash boards pre or post the incident. We have reported the issue to Acura but there has be no resolution to the issue.

Starting around 20,000 miles, my car started to majorly hesitate when I would step on the pedal trying to accelerate. Over time the problem became increasingly worse to the point where the car would slip into neutral causing a major hazard driving on the tollway when my car would decelerate when stepping on the gas pedal. This has caused me to have several very close near accidents. The dealership would keep saying that they could not replicate the problem. I have taken my car in on 8 separate occasions for this safety concern (4 different Honda/Acura dealerships trying to get help since the place I bought the car wouldn’t not help with a solution.) My car has also begun back rolling (15+ feet) when in drive. And yesterday, suddenly accelerated from 0 to 35 when waiting for our driveway gate to open. There are major issues with sudden acceleration when driving a speeds under 20mph and deceleration issue when stepping on the gas pedal trying to accelerate. I have opened a report with Honda over a year ago and keep getting the run around.

The contact owns a 2020 Acura MDX. The contact stated while driving approximately 40 MPH, the collision mitigation braking system inadvertently activated. There were no warning lights illuminated.

7/28/2022

On two separate occasions (December 2022 and April 2023), the Collision Mitigation System (CMS) of our 2020 Acura MDX improperly engaged. On the first occasion, the CMS abruptly engaged the braking system without warning. There was no car in front of the car, but there was a car in a turn lane to the right of the car. There was no reason for the system to engage. Both the driver (my wife) and the passenger (daughter) reported back pain from the incident. The driver received physical therapy for the event. The dealer (Gary Force Acura) and Honda America were notified. The dealer examined the car and found no issues or failures. On the second occasion, the car was changing lanes at a slow rate of speed while approaching an intersection and a stopped car well in front of the Acura. The CMS again abruptly slammed on the brakes in a manner not corresponding with the risk or danger of the situation. A collision with the car behind our car was fortunately avoided by the driver of the other car. The violence of the braking system caused damage to the braking system. No injuries were incurred. Again, the dealer and Honda America were notified, and the car was again examined. No issues or failures were identified outside of the brake repair. On both occasions, individuals were put at risk. The dealer was not able to reproduce the problem. The dealer said a CMS warning to brake should have come on before the CMS engaged. On both occasions, no warnings were observed until the actual braking event started. We are not comfortable driving the car, particularly with a student driver in the family. In most cases, we turn the CMS off before driving the car. The intent is to dispose of the car due to concern associated with the CMS.

LANE DEPARTURE: WARNING

7 Reports3% of total

Previewing the first 2 complaint summaries.

While at a stoplight, my car notified me of many sensors having "problems" From my understanding, it relates to the front camera located on the windshield. I am unable to use these additional safety features since the problem arose earlier this week. Had this gone out while I was driving, my family and I could have been fatally affected. My cursory research online shows this is a recurring problem that customers need to address independently. All expenses are paid from their own pockets. There were no warnings prior to the system's failure. I have not taken my car in yet for this to be addressed. I am frustrated that this is a known issue with no proactive solution by a brand I had trusted.

### 1. **What component or system failed or malfunctioned, and is it available for inspection upon request?** The rearview camera system in my 2020 Acura MDX has malfunctioned. The camera, which is integral to several safety systems in the vehicle, has failed, causing significant safety concerns. The vehicle is available for inspection by an Acura dealership or independent service center upon request. ### 2. **How was your safety or the safety of others put at risk?** The malfunction of the rearview camera directly impacts the **Collision Mitigation Braking System (CMBS)**, **Adaptive Cruise Control (ACC)**, and **Lane Departure Warning (LDW)** systems. These systems rely on cameras and sensors to detect obstacles, maintain a safe following distance, and alert the driver when switching lanes. Without the proper function of the rearview camera, these safety systems become unreliable, increasing the risk of head-on collisions, rear-end accidents, or unintended lane changes, which could lead to a serious crash. Furthermore, the area surrounding the malfunctioning camera becomes dangerously hot, posing a burn risk when touched, which adds another safety hazard. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes I have taken the vehicle to a dealership for a formal inspection, I have confirmed the issue through the consistent malfunctioning of the camera. The overheating and failure of the camera have been present since the issue began, and I have communicated this to Acura's customer service. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the manufacturer beyond the initial communication with Acura’s customer service. No inspection has been conducted by the police or insurance representatives. However, I have made Acura aware of the problem, and the customer service team, led by Account Manager Monica

FORWARD COLLISION AVOIDANCE: WARNINGS

I'm not sure if there is a problem with any of the components, but the radar sensor malfunction impacted the vehicle's braking system. Situation: On [XXX], I was driving with my wife and her nephew from my home (Ankeny, IA) to Indiana on [XXX] [XXX] and [XXX] [XXX] . It was snowing that day. As usual, there were other vehicles on the highway, semi-trucks, pickup trucks, cars. The snow was splashing on to my front bumper, lights, radar sensor and windshield. As it was snowing, I did not engage the cruise control feature. We were around 30 miles from Iowa City, I was passing a semi-truck, a message was displayed on the dash to clean the radar sensor. I thought of pulling over in a safe spot to clean it up. At the same time, "front collision off" and "brake system" icon lite up. The road also changed from downhill to uphill. Suddenly, the vehicle started swaying in my lane, towards the semi-truck wheels and towards the guard rails. I was able to control the steering and come to a stop. That was a near death experience. I got my breath for a minute and cleared the radar sensor. After cleaning the radar sensor, the vehicle was driving fine going up and down the rolling hills of Iowa. Concern: Why a blocked radar sensor should impact the braking system? I understood the impact to adaptive cruise control and front collision features. Are the traction control, ABS, or some other system disabled due to malfunction of the radar sensor? Can the radar sensor wires being bad disables the braking ability?

On my 2020 MDX the rear tail light is filling with moisture and water causing the tail light to fail. There is already a recall from Acura for 2014-2019 MDX for the same issue. Apparently Acura did not correct the issue for the 2020 models which uses the same part and did not address the issue. Acura needs to include the 2020 MDX as part of this recall as well. This is a safety as if the light fail can cause a serious accident.

Left rear inner tail light is inoperative. There is evidence of water intrusion in the lower left corner of the tail light assembly. Called dealer, was told by service manager that the concern was not covered under warranty as the vehicle has just over 51,000 miles. Called Acura Care and was told same. 2014-2019 models of this vehicle were recalled for this issue, but not the 2020 models, although they are the same body style and share same tail light part number. The lights are LED and have no replaceable bulbs; entire assembly must be replaced.

TIRES

Safety issue for Continental Cross Contact LX Sport tires that were OEM tires on 2020 Acura MDX. I've had to have 3 nails removed from tires in just over 2 years of owning this car. So I've had tires inspected quite a bit. Also, every time I had oil changed (at Acura), they would rotate the tires and also inspected them. Every trip to Discount Tire, I was asked if I was rotating the tires because they noticed uneven wear. Now at 29K miles, the current rear tires are at 4/32 and front at 6/32. Latest nail removal visit, the discount tire rep mentioned he was going to research these tires and why they would be wearing this prematurely. He noted the rear tires had exceptional wear on the outer tread and noted this could cause the tread to separate. This concerned me so I researched myself and found many instances of complaints where this line of tire has failed due to that exact issue, the tread separated and their tire immediately went flat. The driver had to get off the road quickly and safely to avoid a wreck. Further research revealed that this tire HAS been recalled, but only for 3 specific sizes, which does not include the size of tire on my Acura. The complaints covered a multitude of vehicle brands that most likely use these as OEM and a wide range of sizes of this tire line. Including Acura, Audi, Tesla, Chevy blazer, VW, and Jaguar. I believe the whole tire line needs to be recalled, not just 3 sizes, for everyone's safety.

My 2020 MDX with less than 52,000 miles (VIN [XXX] ) has a transmission problem. I serviced the SUV as recommended by the dealer regularly and I take very good care . The transmission jerks several times when taking my foot off the gas to slow down within my short drive to and from work. If I parked on a little uphill or downhill roads and switch gear (either forward or reverse), the car jerks and jumps. I mentioned the issue to the dealer 3 weeks ago but of course couldn’t find any issues. Please advise. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Acura has failed to repair my vehicle with a known recall for a year. I am told they're prioritizing symptomatic vehicles and have no ETA on all others. Why have a recall of a safety feature and not actually handle the recall timely. I prefer not to wait for an injury or incident before this is given the proper attention.

Just recently purchased an 2020 Acura MDX AWD with Tech package. Noticed that the windshields have distortions near the A pillars, which happens from both driver side and passenger side. I feel nausea when looking through the window corner as objects are curved. I did a lot of research and found this issue has been there for a while. Distortion in windshield has safety issues that should be address by Acura.

SEAT BELTS

On May 30, 2024, the vehicle associated with the VIN associated with the report was involved in an accident. The vehicle is inoperable due to the seatbelt no longer working since the accident. The vehicle is at the collision center of my choice, and all repairs except for the seatbelt have been made. The collision center and I have reached out to American Honda Motor Company, Inc. and Acura several times. As of date, there has been no resolution and no estimated date of when a seatbelt will be issued by American Honda Motor Company, Inc. and/or Acura. I was told by an employee at American Honda Motor Company, Inc. that the seatbelt will become inoperable whenever the vehicle is in an accident or collision. I feel American Honda Motor Company, Inc. has and continues to produce unsafe vehicles and vehicles where repairs cannot be made promptly. Seatbelts are important, and I honestly believe seatbelts save lives. But, for a company to have a shortage of seatbelts with no estimated time of when one will be issued is unacceptable. And for the company to produce vehicles with seatbelts destined to not function after an accident is a problem. As a consumer, I would like this company to be held accountable for producing vehicles with problems and additional problems if the vehicles are in an accident. I've tried resolving this matter by contacting American Honda Motor Company, Inc., Better Business Bureau, and now NHTSA. I feel this is way beyond what a consumer should have to do.

SUSPENSION

1 Report0% of total

Previewing the first 1 complaint summaries.

I brought my 2020 Acura MDX with 61,086 miles on it for a routine service and was informed that the front suspension control arms were failing and needed to be replaced within weeks otherwise it could break causing a safety issue while driving. I have never had a car including prior MDX's that required this to be replaced and when I asked about it, I was told by the dealer and other dealers that I spoke to that is was unusal for this to happen with this many miles but it can. I feel that this is a manufacturer flaw and could be an issue in other MDX's. Again, if I did not go in for routine service at that time, it could have resulted in a safety incident within weeks according to them without notice and there was no mention of this with my prior routine service back in June 2024.
