Acura RDX 2021.Faulty seat weight sensor front passenger seat. My wife is petite, [XXX] " and weighs [XXX]. When she sits in front passenger seat, at times, the seat weight sensor doesn't register that she's sitting in the seat and the air bag is not engaged. intermittently, the SRS light illuminates but many times it doesn't. I've taken the vehicle into the dealer (Chevy Chase Acura, Bethesda, MD) and they say there is nothing they can do when the SRS light is not on. I've brought the vehicle into the dealership several times. They say that parts are limited and not generally available and are expedited only when the SRS light is illuminated. I've called and spoken with American Honda Customer service and they refuse to help stating the same thing the dealer says. But this is definitely a safety issue. NHSTA Recall # 24V-064. Service Bulletin # 24-015. Please help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Windshield washer pump has failed due to washer nozzles being clogged. Washer pump replaced, but still will not work as the nozzles are clogged. Nozzles are on back order, so therefore unable to clean windshield while driving. No idea when the nozzles will be in stock as this item is on critical back-order.

Structure

The panoramic sunroof makes popping sounds when I drive the car up or down ramps or curbs at angles that twists the chassis. This could potentially break and shatter the glass on top of the driver and passengers or worse dislodge from the mounting bracket and fall into the cabin of the car.

I took my 2021 Acura RDX to Pohanka Acura Service, Chantilly, VA 20151 after I noticed broken rear door weather strips on both sides which is very unusual for a new car. Dealer said it is not covered under warranty. Then I got them replaced by paying the full price for this to the dealer. I contacted the corporate HondaUSA for reimbursement for this issue and they said it would not cover under warranty. Even after they replaced the old weather strips with the new ones, I noticed same issue but at other location (weather strips were not attached to the doors at the corner). I took it back to the dealer again to fix and they said they cannot fix it as all RDX have same thing and they showed me some new RDX and I found the same issue in that car also. I am concerned whether these gaps will cause any problem due outside rain, wind, dust etc.

Remedy is available for the recall, but Honda will not fix the recall on my 2 vehicle’s that I own with this open recall. They are saying 2025 maybe. Unacceptable.

My sunroof exploded for no reason while traveling at highway speeds. Fortunately my sunshade was closed preventing shattered glass from entering the cabin which could have injured me. Shattered glass also damaged the paint on top of my vehicle which will require repainting. The noise made by the glass exploding startled me and could have caused an accident in addition to the glass that flew off of the vehicle endangering vehicles behind me.

Panoramic sunroof has made popping noise when pulling into driveways 4/5 times within 3 weeks of owning vehicle. Have taken to dealer twice and they claim they cant replicate issue. I have recorded this noise during driving and shown to dealer but they refuse to fix. They have knowledge of issue and issued technical service bulletin requiring new sunroof and bolts because the current sunroof bolts and frame can not support its weight when vehicle flexes. Glass is at risk of shattering during vehicle operation.
