2020 Acura MDX Engine Problems

Drivers of the 2020 Acura MDX have reported various engine issues, including sudden shutdowns, stalling, hesitation, and complete engine failure. Many complaints filed with the NHTSA describe instances where the engine stalls unexpectedly during use, often without any prior warning lights.

The 2020 Acura MDX has been subject to two recalls related to fuel pump issues, identified under NHTSA recall numbers 21V215 and 23V858.

Additionally, this vehicle faced a significant engine system issue that prompted a recall in 2023. Specifically, the problem involved damage to the engine from wearing and seizing of the connecting rod bearing.

This defect could cause the engine to malfunction or stall while the vehicle is in operation, posing potential risks of fire, accidents, or personal injury.

The engine recall, identified by NHTSA Campaign Number 23V751 and conducted by Honda, affected approximately 248,999 vehicles.

2020 Acura MDX Electrical System Problems

The 2020 Acura MDX has been associated with several electrical issues reported by drivers. Common problems include frequent occurrences of dead batteries, malfunctioning door locks, issues with the rear hatch failing to lock or unlock properly, windshield wipers that intermittently fail to operate, and turn signals that do not activate reliably. Users may also encounter glitches with the vehicle’s Apple CarPlay and Bluetooth systems.

Acura drivers have also noted problems with the vehicle’s start/stop functionality, experiencing instances where the vehicle unexpectedly loses power while in motion or refuses to start altogether using the start/stop button.

Various reviews on NHTSA’s ratings website mention issues with the 2020 MDX’s forward collision avoidance system such as “phantom braking,” or sudden braking without an apparent cause. Emergency braking warning lights may accompany this problem.

2020 Acura MDX Structural Problems

Structural issues in the 2020 Acura MDX have raised concerns, as it was recalled due to a loose fastener on the brake booster assembly, which can lead to the separation of the brake master cylinder.

This separation poses a serious risk as it could result in a loss of brake function, significantly increasing the potential for a crash. Honda initiated a recall identified by NHTSA Campaign Number 23V458, affecting approximately 124,077.

Additionally, another critical concern involves the air bag system, specifically regarding the potential for unintentional deployment during a crash. This issue, covered under NHTSA Campaign Number 24V064, affects certain 2020 Acura MDX vehicles. It stems from a front passenger seat weight sensor issue that may crack and short circuit, potentially causing the air bag to deploy incorrectly.

    2020 Acura MDX Owner Complaints

     

    1. NHTSA Complaint

    “I was on a bridge heading into a tunnel stopped due to traffic and the car shut off completely. The screen said to put the car in park and restart it. I tried several times and after a few attempts it started back up. This is the third time this happened. I had a recall when I purchased it and had the recall addressed for the same issue. Now I am back at Acura again. And being told I may have to pay for diagnostics. The car is still under warranty.”

    1. NHTSA Complaint

    “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.”

    What the Lemon Law Can Do for You

    The lemon law provides legal recourse for consumers who own or lease defective vehicles that require repeated repairs within the manufacturer’s warranty period.

    This is particularly pertinent to owners of the 2020 Acura MDX facing persistent issues. In California, the lemon law mandates that a vehicle undergo a “reasonable number of repair attempts” for the same issue before it qualifies as a lemon.

    Typically, this ranges from two to four attempts, adjusted if the defect poses significant safety risks. If the issue persists, repairs must continue until the vehicle meets the statutory repair attempts.

    For 2020 Acura MDX owners, issues such as transmission problems, brake failures, and other defects can qualify the vehicle for a lemon law claim if they persist after multiple repair attempts.

    Once owners suspect their vehicle may qualify as a lemon, they should consider filing a claim against the manufacturer. Consulting with an experienced lemon law attorney can streamline the process and enhance the chances of achieving favorable outcomes.

    Remedies under California’s lemon law include either a full refund or a replacement vehicle. A refund covers the purchase price and any associated costs, while a replacement typically involves a similar make and model vehicle, often from the current model year.

    Manufacturers may deduct a usage fee to account for the trouble-free miles the vehicle has been driven. In most cases, the consumer is responsible for any price difference if they receive a replacement vehicle.
