Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I discovered severe frame rust under my rear bumper cover. Large chunks of rusted metal are easily pulled off by hand. I'm concerned about the ability of the bumper/frame to prevent serious injury to my family in the event of a rear collision. The pictures I've submitted are at least three years old. I suspect the situation has deteriorated since then. These were the pics I submitted to Acura at that time, when they informed me they could do nothing as my vehicle was out of warranty. …”

“Purchased new in 2004. During maintenance I found the rear frame behind the bumper covering to be severely rusted. Not surface rust but chunks that I can easily pull off by hand. Concerned about the structural integrity of the vehicle and my safety I contacted Acura consumer relations. Spoke with someone who just said they can't help because my vehicle is out of warranty. I feel that something is probably wrong with their materials used to allow such severe rust to occur and eat away at the frame.”

“My Acura MDX 2004 has had the window regulators replaced three times and now both windows are broken again. When the window slams down into the door frame it makes a terrifying noise which has caused me to nearly wreck twice. The worst incident was when a regulator failed and I caught a piece of plastic road debris in the face (couldn't close the window) going approx 70mph on the freeway. I have a scar on my forehead and was covered in blood. I thought that I had bad luck for a while, but have researched it, and this is not just me. Thousands of honda and Acura drivers have the same problem. …”

“The airbag light warning continues to come on and stay on. Sometimes is goes off, but comes back on later. This was reported to the dealer in charge of airbag recall and the only solution offered was paying a hefty fee to diagnose the issue without guarantee. This was reported in 2014 and has been an ongoing problem before this and currently, 2019.”

NHTSA complaint #11205617, filed 2019-05, 90,000 miles

“Reproducibly at automatic transmission shifting speeds between 20-25mph, 30-35mph and 40-45mph there is an audible and palpable shudder as the transmission hesitates prior to shifting. Have brought vehicle to Acura dealer 3 times over the past 5 years, every time stating the same complaint, and every time referencing a convincing multitude of Acura MDX owners noting a similar problem. Every time Acura service states they could not reproduce the problem and nothing is wrong with the vehicle. …”
