NHTSA Complaints · Active Recalls · California Lemon Law Data
The NHTSA tracks consumer complaints, manufacturer recalls, and safety investigations for every vehicle sold in the United States. These publicly available records are a critical resource for California lemon law cases because they establish patterns of recurring defects.
As of June 2026, the NHTSA has not yet received complaints specific to the 2024 Acura MDX. However, this does not mean the vehicle is free from defects. Complaint data often lags behind real-world issues, and many vehicle owners experience problems before they are widely reported. If you are experiencing recurring issues with your 2024 Acura MDX, you may still have a valid lemon law claim. You can file your own complaint at SaferCar.gov and check for updates on the NHTSA database.
The 2024 Acura MDX has generated 62 NHTSA complaints and has 1 active recall. If your 2024 Acura MDX has experienced a defect that the dealer has been unable to repair after multiple visits, you may qualify for a full repurchase or replacement under California lemon law. Acura pays all attorney fees when we prevail. You pay nothing.
The 2024 Acura MDX has generated 12 NHTSA complaints for this defect category. If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “AC / DEFROSTER / HVAC I am reporting a potential safety and health defect involving the HVAC system in my 2024 Acura MDX. When operating the air conditioning or the front windshield defroster, a strong musty odor enters the cabin. The dealer informed me that resolving the odor requires an EVAP core cleaning, replacement of the cabin filter, and the use of a disinfectant that will be circulated throughout the ventilation system to kill mold, mildew, and other contaminants. I was told this is the “first step” in addressing the issue and that the estimated cost is $440 out of pocket. This is extremely concerning because the presence of mold or bacterial contamination inside the HVAC evaporator and ventilation system affects the air my children and I breathe inside the vehicle. Mold exposure can cause respiratory irritation, allergic reactions, headaches, and other symptoms, especially in enclosed spaces. The HVAC system in this vehicle is a sealed, manufacturer-controlled system which the owner cannot access or service, so this type of contamination should not be considered routine maintenance. I have researched this issue and found that Honda/Acura vehicles have a documented history of HVAC mold and mildew odors, and Honda has previously issued internal investigative bulletins requesting dealers to collect parts from vehicles with musty HVAC smells. There are also mold-related complaints already filed with NHTSA for the 2024 MDX model year. This suggests the possibility of a broader engineering or design issue. I need this issue addressed immediately for health reasons, and I may have to initially pay out of pocket to ensure my family’s safety. However, I believe this is a safety-related defect that Acura should be responsible for correcting, not the customer, especially on a relatively new vehicle still under warranty. I am requesting that NHTSA document this case and consider evaluating whether a pattern of HVAC mold contamination exists in newer Acura vehicles.” (NHTSA Complaint #11700100)
Brake defects affecting safety may qualify for California’s two-repair threshold under Cal. Civ. Code § 1793.22, which applies to defects likely to cause death or serious bodily injury. The 2024 Acura MDX has generated 8 NHTSA complaints related to braking, including ABS failures, grinding, reduced stopping power, and warning lights. Owner reports include: “To: Consumer Financial Protection Bureau (CFPB) Subject: Urgent Complaint – Illegal Repossession, Lemon Law Obstruction, and Compensation Claim Against Honda Financial Services Dear Sir or Madam, I am filing a formal complaint regarding the illegal repossession of my leased 2024 Acura MDX, VIN [XXX] , account number [INSERT ACCOUNT NUMBER], by Honda Financial Services. This repossession was conducted without any prior notice, without communication of the date, time, or location, and without any legal authorization or court order. 1. No opportunity to respond or act • I was outside the country at the time of repossession and had no chance to respond or protect my rights. • The vehicle was removed one day before my arrival, despite my sister attempting to coordinate that the vehicle be held because my mother is seriously ill and could not make payments. • The vehicle had been immobilized for 4 months due to brake and acceleration defects, which were part of a manufacturer recall affecting all MDX vehicles. 2. Illegal and premeditated removal • My vehicle was removed from a private garage using a towing company, without a court order, without my consent, and without legal authorization. • Video evidence clearly shows the doors were closed; the individual opened them himself, deliberately removed the license plates, and covered his face to avoid surveillance cameras. • These actions constitute intentional concealment, unlawful seizure, and theft, not a lawful repossession. 3. Obstruction of Lemon Law claim • Honda Financial never took the vehicle for inspection or repairs, deliberately preventing evidence of factory defects that rendered the vehicle unusable for over a year. • After multiple attempts to resolve the issue, Honda Financial claimed they have no record, effectively denying rightful compensation and acting in bad faith to sabotage my Lemon Law claim. 4. Violation of federal and state laws • Uniform Commercial Code (UCC) § 9-609: Prohibits reposses INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)” (NHTSA Complaint #11696964)

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2024 Acura MDX:
Once the presumption is triggered, the burden shifts to Acura to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Acura must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2024 Acura MDX qualifies as a lemon under California law, Acura may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Acura a reasonable opportunity to fix the defect. Visit different authorized Acura dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Acura pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Acura a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Acura is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
