2022 Acura MDX: grinding or squealing brakes

Filed Aug 31, 2026 · Transmission · IN

While driving home on a Sunday afternoon, out of nowhere, a very loud pop sound happened followed by grinding. We were so worried that my husband pulled over thinking we had done major damage to the car somehow. Visual inspection under the car yielded nothing leaving us puzzled. No warning lights came on before, during, or after. We had it taken to the Acura dealership in Fairfield, Ohio. The car was still within warranty at this time, and they found nothing nor could they replicate the sound. My husband explained that it sounded to be transmission related. They chalked it up to a loose tie rod end which they “tightened” to solve all of our problems. We left the dealership and took the car home experiencing no further problems. Fast forward to the winter of that same year we realized that no matter what mode we put the car in we didn’t have AWD. Still no warning lights. The following spring, approximately 20,000 miles after experiencing the first loud pop and grind, we started getting error messages on our user dashboard. “All wheel drive system problem. Only front wheels may be powered. See your dealer”. We immediately scheduled a service appointment with the same Acura dealership. Within minutes of having the car examined on the lift the Acura certified technician found the problem to be the AWD transfer case and additionally the transmission. Stating we would need to replace both. They came back with a quote of approximately $18,000 for a new transmission, transfer case, labor, and all associated materials, for which we declined. Currently seeking help for recall as we do not believe a transmission/ transfer case should fail so quickly under normal driving circumstances.

Brake system warning light comes on and says reduced braking take to dealer. Auto hold brakes don't always hold. Rear brakes non stop squeal and grab un predictably. I am unsure when and if the brakes will work in the rear. The loud noise from the rear squeal has caused others in traffic to flag me down and warn me something is wrong. The noise is also made it impossible to have my Autistic nephew in the vehicle with me as it triggers episodes and scares him. I have asked the dealer to please repair the rear brakes several times. They refused and instead replaced the front brakes, then admitted it is the rear brakes but refused to repair them. Honda of America also refuses to repair rear brakes. Based upon false statements on the work order the statement from the dealer is the rear brakes on the MDX are supposed to be like this. This vehicle has issues with the warning light while stopped and moving, and the noise and unsafe braking is at all speeding from 1-60 mph. Forward and reverse is malfunctions. I asked Honda America to repair which they won't then I ask them is the official statement these brakes are okay and safe as is and they will not say that either. I have driven similar models of this vehicle and it does not do the same thing, no noise, or warning lights, and the brakes preform safely and consistently. Mine do not. Honda of America does not want to repair the brakes under the warranty. They also incorrectly stated on repair statement that humidity and car washes can make the brakes do this. I have been in northern non humid states during winter and never use a car wash. They just use this as an attempt to not repair the brakes.
