The malfunction was both rear drains from the sunroof were clogged and possibly kinked. The dealership might still have the components but did not give us access to them. The clog caused the water to enter the vehicle and accumulate. In addition to wet carpeting, an electrical component shorted and failed damaging the Infotainment system. If this had happened during vehicle operation with water moving around, electrical systems could suddenly fail while driving. The vehicle was inspected by the insurance adjustor but was deemed a maintenance issue even though there exist no maintenance instructions or dealership directives for maintenance or inspections. Owner maintenance would not be possible as special tools would be needed without which damage to the drain lines might occur. There was no warning, messaging, or instructions that maintenance was necessary for this item or that it could fail. The first sign was the sound of sloshing water in the vehicle during driving and the failure of the infotainment system. As a remedy, the dealership insisted on replacing the drain lines rather than cleaning them out, which implies that either the dealership was creating extra work for themselves or the drain line could not easily be cleaned.

My 2022 Acura MDX A-Spec developed an electrical problem where I heard an extremely loud pop come from the stereo system before it stopped working and then the infotainment screen stopped working as well. I took it to the dealer who determined that a water leak in the sunroof drain plug caused the interior of the vehicle to become saturated with water and cause corrosion to electrical bundles. By searching the internet, I found that this was a known manufacturer’s defect with this specific model that had been made known to the dealership and they did nothing about it. Having an electrical problem could have put us at risk had things stopped working at an inopportune time on the highway or caused a malfunction at a critical time while driving. I submitted a request to Acura for an extended warranty of this problem, but that request was denied. They said that there had been an extended warranty for this issue, but that it had expired somewhere between March 2025 (when my normal warranty expired) and October 2025 (when I took it to the dealership for an evaluation of this problem). Acura wouldn’t say when that was, but I was surprised that they were of no help. As I mentioned, this is a known manufacturer’s defect that should have been checked per my normal maintenance visits, but it was ignored until it became an actual problem. They certainly could have been more proactive and it would have saved us a lot of time and expense.

May the water leak causes fire . I have many issues going on on my new 22 MDX 7k miles on it , the car is acting crazy no keyless entry working, remote is not working, I called many dealers after they checked it they said we have to keep the car for few days because there's water leaking on the driver side, it was a shocking for me that a brand new car having that, I called the worst company ever Acura and i told them i need a replacement or buy back I'm not agree to fix a brand new car and go through this hassle for years, they was very aggressive and not professional or fair and the case manager hange up on me (Jassica) she refused to let me speake to her manager or supervisor, she said just have to leave the car at the dealer for few days without loaner or reimbursement!! Is it fair ?! And she started to give reasons for the problem which is not true, now I need help to get it done.The worst after sale service ever It was one of my big mistakes that happened to my life to buy Acura !
