2019 Acura MDX Electrical System Problems

My car has stalled while driving on the highway multiple times now. The first time it happened, it lost power, stopped accelerating, and cycled through multiple warning lights, causing a significant safety risk. I pulled over and it restarted within minutes. I took it to a repair shop and they could not find a problem with it, even with the codes provided. Nothing pointed to a solution. It happened two other times while I was driving my child on a highway where it lost acceleration and then kicked back in. Again, this post, a significant safety risk as always in a fast lane on a highway with my child cars behind me had to hit their brakes to avoid me after this incident. Other times it doesn’t lose power, yet it cycles through warning lights randomly. I took it to the dealer instead of a local shop. They texted me about items that should be fixed per an inspection, including struts and a battery replacement. Complete with a large bill just for diagnostics. Yet, nothing was found having to do with the main problem at hand. Losing power while driving. . My battery is less than six months old. I had it tested and it is fine. My vin is not listed in the recall, but, all of the symptoms match the other recalls of the same year make and model.

Since the purchase of my Acura MDX 2019, the following problems have been reported to the dealership and to Honda Manufacturing Inc. without any resolution. The dealer shop has replaced recall parts, but the problems persist and have not gone away. The vehicle stalls and stops working while driving. The engine makes knocking/rattling noises upon becoming disabled while driving.The engine would randomly not start when turning it on. When car becomes disabled the dashboard lights up warning lights displaying messages intermittently of the following problems: Anti-Lock Brake System Problem (ABS), Vehicle Stability Assist (VSA), Hill Start Assist, Trailer Stability Assist, Collision Mitigation System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist, Brake System, Brake Hold System, Electric Parking Brake, SH-AWD, Keyless Start System and Power Steering System (EPS) Problems, while displaying ACC and LWKS codes. Additionally, the vehicle runs improperly and shuts down completely making the window, doors, etc, inoperable while passengers are inside locking me in and my entire family for long periods of time. A few times has left me either myself or with my children and dog inside. The only place where I take my car for services is where I purchased it (Chevy Chase Acura). The issues noted are the same reported by the recalls I have received, and I have not taken it somewhere else because of that reason. Nobody can fix them as the problems are manufacturing issues that even Acura/Honda cannot repair. This safety defect can kill or seriously injure me, my passengers, and other drivers on the road. As noted in one of the many recalls the fuel pump defect can cause the vehicle to stop in the highway and could prevent an engine from starting or cause a vehicle to stall while being driven, it potentially increases the risk of a fire, crash, or injury. My car continues to have these issues and nobody is helping me. Please help!

Turned on my car last night and many lights appeared including emissions system problem, electronic brake problem and SH-AWD malfunctioning. All the lights came on at once. According to forums, this is happening with many Acura RDX, MDX models and manufacturer does not have a clear way to repair or resolve the issue. My car has had all the routine maintenance and is scheduled for the 2 recalls to be repaired next week.

Vehicle is getting errors for Emssions controls, parking brake, and sh-awd system faults all at the same time. Car will still function normally and codes will go off and come back intermittently. Also while reading the codes it will get a U3006-16 code for low voltage on the ecm. Confirmed battery is good under load test and alternator is charging at 14.2 volts.

Electric Parking Brake Problem and Emission System Problem lights came on spontaneously

I was driving down the highway today at 70 mph and all the lights illuminated on my MDX. It began to struggle to keep speed and eventually shut down once I was on the service road. I was extremely scared and nervous that I was going to be involved in an accident or the car was going to blow up as it started bouncing up and down while I was still on the highway.

Infotainment system randomly becomes unresponsive and the screens will go black. The dealership stated that my phone was causing the issue. This is not true as the issue has happened when my phone is not in the car, phone is in the car/connected via bluetooth, in the car/connected via apple carplay (wired connection). This could be dangerous during the summer as these screens control the temperature controls and some of the safety systems.

I was yielding to make a left hand turn , in the middle of the intersection, and my car turned off and wouldn’t turn back on. In addition the car occasionally jerks as I’m driving almost like if it changes gear. Sometimes I can’t get the car in park position I have to press the button multiple times. The recall going on right now can cause a fire crash or injury and they cannot replace the parts until April 2024 and I don’t feel safe driving my car.

The back inner tail light on my car is not working, which is the following recall, however, according to acura, my vin does not apply and does not show a recall. I believe this is an error since I am having the exact issue and my vin should be included in this recall. NHTSA RECALL NUMBER:19V-256 MFR CAMPAIGN ID:M49 CAMPAIGN DESCRIPTION:2014-19 MDX Tailgate Inner Taillight Safety Recall RECALL DATE:03/28/2019 RECALL STATUS:17 Character VIN Required

During normal driving transmission will shift to Neutral, locks the system, and engine does not start when automatic idle stop had been engaged at stoplight or stop sign. Instead of restarting the engine, the feature causes the transmission and electrical system to lockup taking quite a bit of time to convince the car to restart.

UNKNOWN Over the course of a couple weeks, engine has intermittently stalled while driving, forcing me to turn off the car in the middle of the road. Progressively, other electronics have also intermittent failed including power steering and infotainment system. All dashboard warning lights are on and do not resolve by turning car on/off. Generally, car is driveable until the random intermittent stall, which is obviously dangerous. 2 weeks ago, car had gone through state inspection and 30k mile maintenance without issue. Service station checked battery and alternator and no issues.

The Car shut down in engine idle and would not restart. It was unresponsive and took 5 minutes for the start button to function. This occurred in the middle of a busy intersection. 2 weeks ago Acura performed an update to the software that was supposed to resolve the engine restart issue, but clearly it has not.

The contact owns a 2019 Acura MDX. The contact stated that upon locking the doors with the key fob, the vehicle would remain unlocked. Due to the failure, the contact believed that someone entered the vehicle and changed certain setting from the original setting. The contact was informed by the dealer that the setting change should not have shown on the multi-information display (MID) screen. The manufacturer was notified of the failure. The vehicle was not diagnosed or repaired for the failure. The failure mileage was approximately 40,400.

When stopped at a light or in traffic the vehicle engages the auto idle feature. (turns off the engine to save gas). Upon releasing the brake, the car should re-start, instead the car does not start. The car jumps out of the drive gear into neutral on the transmission. The electrical system goes crazy and does not allow you to either turn off the car's electrical system or re-restart the car using the car's on/off button. This has happened to me at least 5-10 times over the last year. Each time the car becomes immobile in the middle of the road or highway for up to 2 minutes, until the electrical system resets and allows you to turn off all the power and re-start the car. It's a very scary and dangerous situation, when my vehicle is stranded in the middle of a highway or a road for up to 2 minutes, as traffic tries to avoid crashing into my vehicle. Searching online, I was able to see that this same condition has affected many MDX owners but Honda does not seem to have recall or fix for this issue.

The contact owns a 2019 Acura MDX. The contact referenced NHTSA Campaign Number: 21V215000 (Fuel System, Gasoline). The contact stated that after refueling the vehicle and driving several miles, the fuel gauge fluctuated to empty. The contact stated that the fuel gauge would indicate the incorrect amount of the fuel in t fuel tank. No warning light was illuminated. The vehicle was taken to the dealer where the failure could not be duplicated. The manufacturer was notified of the failure and the contact was informed that there was no recall on the VIN, and transferred the contact to the NHTSA Hotline. The failure mileage was approximately 44,000.

While in traffic the auto start sometimes fails to engage and the car stalls. Battery lights come on and the car goes into neutral on its own. I have to sit there and wait about 5 minutes in traffic before it restarts. Battery checked out fine. It has happened 3 times now. This is dangerous, and can/will cause a collision.

The contact owns a 2019 Acura MDX. The contact stated while at a stop light and attempting to make a left turn, the vehicle lost motive power and stalled. The contact stated that a warning message to "Park and Restart” the vehicle was displayed. The contact shifted the vehicle into park(P) and attempted to restart the vehicle however, the vehicle would not start immediately. The contact stated that after several attempts the vehicle restarted. The vehicle was taken to the dealer and the contact was informed that the brake assist feature had drained the battery. The contact was informed that the battery needed to be replaced. The manufacturer was not contacted. The failure mileage was 32,000.

When the idle stop comes on it shifts the car to neutral and I must shut off the car to get it to start again. This happens while on the highway and is unsafe.

On a few occasions, while at a stop light the auto idle engaged. When I lifted my foot from the brake pedal, which should restart the engine, the car Shifts automatically into neutral and cannot restart the engine. The dash shows a message saying that I must now shift to park. I have to then turn the car off, while in traffic, and then restart. This happens while in traffic, causing everyone behind me to wait or drive around. I have taken this to Acura of Stamford twice already, and they cannot recreate it. I have pictures of the car when it was in neutral. Other people have reported this occurring on a 2019 mdx as well.

I was driving my car with my infant daughter in the backseat. We were stopped at a red light in the middle of a busy intersection. The car was in idle mode. When I went to turn left the car shifted into neutral. I could not go into drive. I had to turn the car off and turn it back on again to get it to move out of the intersection. We almost got rear ended. When my husband brought the car in the shop they ran diagnostic testing and said nothing was wrong. Only that the problem may be caused by a low battery. They replaced the battery and let my husband drive home. I want to know why there was no low battery warning light? Also why do I have to almost have a collision to find out the battery doesn’t work?
