FUEL/PROPULSION SYSTEM
My 2020 Acura RDX is currently non-operational due to a failure of the fuel pump, which is the subject of NHTSA Recall 23V-858. The vehicle suffered a complete loss of power and will not start, posing a significant safety risk should this have occurred while in motion. Despite contacting Acura Client Relations over 30 days ago, no remedy has been provided. My Case Manager states they are unable to offer a solution other than waiting for a "Territory Manager" to make contact—an event that has yet to occur. My vehicle has now been completely disabled for over two weeks. Because I reside in the [XXX] , the manufacturer claims they cannot service the vehicle due to a lack of a local franchise dealership. However, as a [XXX] territory, federal safety mandates apply. Acura has refused to authorize a local certified mechanic to perform the repair or ship the necessary parts to rectify this safety defect in a reasonable timeframe. The manufacturer is effectively denying a federally mandated safety remedy based on geographic location, leaving me with a non-operational, hazardous vehicle and no timeline for repair.

VISIBILITY/WIPER
My car was parked and off at a local park, I loaded my [XXX] son in the backseat of the car and then I got into my car. Before even turning car on I heard a loud pop sound and got out to look around and then realized it was the back windshield shattering. Apparently this is a known issue with Acura where the rear windshield will spontaneously shattered for no reason. Safety wise this is a concern since I have a child in the back seat and glass is shattering into the car as well as outside on pavement .

UNKNOWN OR OTHER, VISIBILITY/WIPER
The rear glass in my 2020 Acura RDX Aspec randomly shattered when I closed my rear driver side door. My car was not running and hadn’t been running for over a hour and there were no signs of impact to the glass. There is a TSB from Honda about this being an issue already. I bought the car used and have owned it for a year. My extended warranty doesn’t cover the rear glass. It was going to cost over $1000 to fix as the dealership would not cover the cost and my car is out of its factory warranty. Didn’t have much choice but to use Safelite. Now there are glass shards stuck in my tailgate and apparently no way to remove them without removing the glass from the tailgate and removing the tailgate from the vehicle. Other complaints show that this can also happen while the car is running and in motion which seems like a major safety concern. With the glass shards stuck in the tailgate my car has been devalued by no fault of own. Honda knows this is an issue but will not issue a recall and it could also be a safety issue.

Powertrain failed in 2020 Acura RDX Tech Pkg AWD. Only 2 weeks after the 6 year warranty expired on the vehicle the powertrain failed and set off the check engine light. Dealer service department found an excessive amount of shavings in the plug. The vehicle only had 41,345 miles on it before transmission/powertrain failed and there was only 1 owner for the vehicle. It was purchased brand new from the dealer and vehicle was well-maintained.

SUSPENSION
2020 Acura RDX Rear Coil Spring snapped in half on left side. Safety concern drove to nearest independent service center to be accessed within 5 miles of incident. Advised not to drive it. Called Acura Dealership. Advised to replace both Left and Right side and have new alignment. No warning lights or other symptoms, just an extremely loud bang to left side while driving. Estimated out-of-pocket expenses: Rear coil springs (both) $600 parts/labor Alignment required $100 Total $700 unless goodwill applies (Acura quoted and independent matched prices (allowing me not to have it towed 15 miles to dealership) This is a corrosion related rear coil spring failure at 72,000 miles in Ohio. I’m asking Acura to consider goodwill assistance because this appears premature for a critical suspension component.” Please open a good will case with Acura Tech Line/Client Relations based on: ✅ Safety-related failure (suspension spring) ✅ Salt-belt state (Ohio — well known for corrosion issues) ✅ Reasonable mileage (72,000 miles is not excessive for a structural suspension part) ✅ Dealer acknowledged the issue (they quoted it and advised not to drive) ✅ No abuse or impact damage (no tire damage, single spring corrosion failure)

ENGINE
My 2020 vehicle lost all power when I was attempting to pass an 18-wheel trailer on the expressway. I took it to the dealership which was less than a mile away. They told me I needed a head gasket replacement @$6500. They replaced the HG and it ran great for 5-6 months. Then exact same thing happened again on expressway. It was another head gasket. After searching online I found a lot of history on my vehicle where the 2.0L turbo engine was failing prematurely.

The rear window has shattered twice (2023, 2026). Both times, the vehicle has been parked in a lot with cameras. After reviewing the cameras no one was near the vehicle. After the first time, I became aware that this was an issue with my model. I contacted the manufacturer and they expressed that my year was not affected by the defect. It just happened again. I contacted the manufacturer again, they expressed, that in order for them to do anything a recall has to be put in place and to report it to you. In addition, I do not put on the rear defrost. I have been driving around with shards of glass in the rear door. Safelite has expressed, due to how the manufacturer built the door, they can not remove all the glass. Also, every time the door is lifted pieces of glass fall out.

To Whom It May Concern, I am submitting a vehicle safety defect complaint regarding my 2020 Acura RDX. The rear window of my vehicle suddenly shattered without any impact, collision, road debris, or external force. At the time of the incident, the vehicle was stationary. There was no warning or visible damage prior to failure. The glass shattered unexpectedly, creating a dangerous condition and risk of injury. I was required to file an insurance claim and have the rear window replaced. I am concerned this may indicate a defect in the glass, manufacturing process, or vehicle structure. I request that NHTSA review this incident, determine whether similar failures have been reported, and evaluate whether this represents a safety-related defect requiring investigation or recall. I can provide photographs, repair invoices, VIN, mileage, and additional documentation upon request. Sincerely, Joyce Burnett Phone: 757-636-6167 (Mobile) VIN: 5J8TC1H57LL013150
