The 2020 Acura MDX is a luxury model that is supposed to offer more than the comparable Honda. It’s known as a “Premium Performance SUV” by the automaker, but this model has a hard time performing at all. With a faulty electrical system, defective engine and malfunctioning equipment, customers are already filing class action lawsuits against the company.

As a luxury model, this vehicle should have every bell and whistle, plus it should all work seamlessly. However, that’s not the case.
Here’s one Edmunds review. “Issues with Apple CarPlay from day one still not fixed it only connects to my Apple IPhone when it wants to even after being swapped out w a loaner car. Acura has no fix. The ac is not near as cold as my old Murano or Toyota’s and just adjusting the heat and ac on the screen is bizarre reds normal heat and ac buttons/controls.”
Acura isn’t attempting to hide any electrical system issues. The company even issued Service Bulletin #BBTS210102 that discusses an inoperable center display. It turns out that the problems are caused by a software bug that needs to be repaired. So far, this performance SUV lacks passion and functionality, making owners wonder why they didn’t buy a Honda and save a little money.
The engine is undoubtedly one of the most important components of any vehicle, but this Acura seems to have some major malfunctions.
Another Edmunds review states, “The start stop feature on this and all other makes of vehicles needs to go away! It interferes with climate control comfort and will be a maintenance issue down the road. The gas savings is minimal and doesn’t justify the inconvenience.”
Acura doesn’t have a lot of information regarding engine problems. However, Service Bulletin #BPaS02102021902 does show that customers are complaining. This communication illustrates how DTCs are being set, but Acura doesn’t know how to resolve the issues. Maybe it’s time to get rid of those designers that simply can’t perform.
With so much equipment on-board, there’s a lot that can go wrong, but it shouldn’t. Customers spend extra on the MDX to ensure a seamless operation.
Yet, this Edmunds review shows they are receiving something else. “Negative I’ve seen is the well reported delay in cruise control response, reference the time it takes the vehicle to move into a new speed when the cruise control is already engaged.”
It shouldn’t surprise anyone to know that there is a pending class action lawsuit against the company, but for something much more dangerous. It turns out that 2016-2020 models have a dangerous issue that hasn’t been resolved. Owners stated that the vehicle does not accelerate as it should after pressing the pedal. They can also decelerate rapidly, shut down without warning and stall, leaving people in a lot of danger. Then, the systems regain power as if it never missed a beat. Maybe this Acura is a “Performance” option, but it can only be the leader at the junkyard. It will win Best in Show.
Think you have a lemon? Sit back and let the experts work out your lemon case at no cost to you. The law makes Acura pay legal fees. You may be able to get your lemon out of your life. Every year, auto manufacturers buy back, replace or pay cash settlements to thousands of ‘lemon’ owners like you.

Description | My 2020 acura mdx shuts down and shifts to neutral while stopped with the auto shut off feature engaged. This happens intermittently and the only remedy is to shut the car off and restart. It only seems to occur when the auto shutoff feature is engaged. |

Description | Twice at a stop light the car went into neutral by itself which then required me to go put in park then drive. One time a police officer was nearby and pulled me over after, asking if everything was ok since I was stopped at the light for a prolonged period of time. I took it to the dealership and they said it was the battery and replaced under warranty. Battery should not go when car has less than 30k miles. I checked forums and many people have experienced this issue. There are too many other complaints on line not to bring this to your attention. It has happened already. It is very nerve racking to be at a stop, hit the gas and go nowhere when traffic is quickly approaching from behind. This will eventually lead to someone getting rear ended. |

Description | When the brake is suppressed at a stop sign or stop light, the vehicle has an auto idle stop feature which shuts off the engine completely to preserve fuel. The vehicle is supposed to restart once the brake is released. In my case, there have been multiple times when the brake is released but fails to restart and go. I have encountered the issue in the following scenarios: 1. Getting off the freeway, if there is a line getting off the freeway, then the vehicle will potentially shut off and fail to restart. This is a safety hazard as the driver behind me or others behind at a distance can potentially hit the vehicle. 2. At a stoplight, especially when making a left turn, the vehicle will shut off and fail to restart. It takes more than 8 secs to restart/reengage by restarting manually. If there are any vehicles attempting to go behind me or at a distance, then they can potentially hit my vehicle. This is a huge risk to my family and I, to assist in our safety, we end up having to turn on our hazard lights. This is unacceptable especially since this is a 2020 vehicle with under 45k miles. I have attempted to reach out to the acura service team, customer relations team and even called the warranty department. However, they were not taking ownership on the issue and responded as it has not been reported before. Based on forums, the issue is being encountered by other owners as well. Hopefully, this can be sorted in the near future for safety of my family. |

Description | The engine idle stop function is unreliable and often fails to restart the engine when the brake pedal is released. The vehicle will, suddenly and without notice, become inoperable and undrivable wherever it rests, whether at a red light or stop sign, in the middle of an intersection while making a left-hand turn, or on an entrance ramp to a highway, causing a dangerous situation for myself and other drivers. It takes several minutes to restart the engine and sometimes must be jump-started. The issue has been reported to my local dealership, and they said it is not covered. |

Description | 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. |

Description | (4/2021). While cruising on a 2 lane hwy the power went to zero. All I could do was coast to the shoulder. Restarted and was on the go. If I was passing another car and this happened when there was oncoming traffic I could had a head on collision. This occurred twice on the same 3 day vacation another time (8/2022) while cruising at normal speed and acceleration in the passing lane on the interstate all of a sudden the power went zero. All I could do was coast into the median to get out of traffic. I didn't have time to check for warning lights. Just restored the engine and all was fine. Totally scary and unsafe. Dealer says they've had no similar complaints. Only thing to do is have it checked but if can't duplicate the problem or find a code nothing they can do thinking of selling it due to not knowing what deadly situation I may be in when it reoccurs. Internet chats are saying it happens to others as well. Where is the recall that should exist? |

Description | 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. |

Description | 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. |

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. |

Description | 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. |

Description | Temporarily loss control of my vehicle when I was exiting the parkway and needed to steer around to avoid a stop car my car just took a big rock in motion from side to side. The steering is very unresponsive, vehicle hesitates when accelerating rapidly and when turning they is no stability. Also my breaking doesn't react the way it should it's very delayed. All of the things that the dynamic mode is supposed to enhance appears not to be functioning. I went to the dealer several times they said they couldn't find anything but yet the problem continues. They also said they reset and relearned some parts of the car in an attempt to rectify the issue I was experiencing. The problem still exists. Many times when I come to a stop on a hill the car roll backwards. I was given the same model on one of my visits to the dealership as a loaner. And it ran like a totally different car the way the car should run it was the same year same model. Everything was more responsive the steering the breaking the suspension even when I started the car the start up sound was much more aggressive. Please help! |

Description | I have experienced sudden acceleration problem numerous times( 5 to six times. The latest one was march 1,2021. The vehicle would accelerate (rpm rapidly ) suddenly when driving at low speeds(around 10 to 15mph to a quick almost 30mph without pressing the gas pedal) that always require me to break immediately to avoid any accidents. I had the vehicle checked thoroughly by a company sent expert last year(sometime nov ,2020) and they can't replicate the problem. Acura relations can't help me anymore . It made me google unintended acceleration mdx. The problem is for real. Had I known this problem, I wouldn't have leased this vehicle last oct. 31, 2019. Please help. Many thanks |

State | MO |
Description | While driving at highway speeds with the adaptive cruise control engaged, the vehicle detects vehicles to the right (same direction of travel) or at times vehicles to the left (opposite direction of travel) and abruptly applied backing. No vehicles will actually be in lane of travel of the vehicle to cause action. On a 87 mile drive (one way to work) happens more than eight times on first drive and over ten time on second drive. Vehicle has under 1500 miles on it and was purchased brand new. Taken to acura and told to turn off lane departure system unless in city traffic. System turned off and did not correct issue. The abrupt braking causes drivers behind to abruptly brake, increasing risk of crash, and also angers them because they think you are 'brake checking' them. Weather was cloudy or clear. |

Description | 1. (july 8, 2020) on 1 occasion within a short time after purchasing mdx, I floored the gas pedal on the highway as when passing another car, let off the gas pedal and the engine kept running as though the gas pedal was still floored. Reported it to dealer and they said they could not duplicate the problem and said maybe the floormat caused the problem. Potentially dangerous. 2. (july 8, 2020) on an incline at a stop sign, mdx will roll backwards after releasing brake and then when pressing on the gas pedal it will lurch forward. Reported it to the dealer. Potentially dangerous. 3. When stopped and then trying to backup on an incline, mdx won't move rearward until gas pedal is pressed approximately 1/4 to 1/3 of full gas pedal movement. It acts as though the braking system is partially applied. This only happens on an incline, not on level ground. |
