There are 1 owner-reported powertrain & transmission complaints for the 2025 Acura MDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The auto start/stop system failed to restart at a stop light. This was an issue on the older MDX and TLX vehicles with the 3.5L V6 which resulted in a large recall. The recall has not been extended to cover the 2025 MDX and the dealership is refusing to fix the issue or acknowledge it despite having a video to prove it occurred. Acura is knowingly selling these vehicles with a dangerous safety defect that will occur at random. Please consider investigating this matter further as I am concerned for my safety and the safety of my passengers.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
