2015 Acura RDX

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

headlights are not illuminating. i took it back to the dealer. they changed my bulbs cost me over $200. and the problem is not fixed. i googled an found im not the only owner who has this problem.

The headlights that came with my car are very dim, which has become a safety issue while driving at night. When I spoke with the dealership, they informed me that this is a known issue with the 2015 RDX; however, there is no factory recall. The dimness is due to the premature burnout of the inside reflective coating in the reflector bowl. The only solution is to purchase a new headlight assembly. I ended up spending $1,500 yesterday to install new headlights. I believe this is a manufacturing defect, and Acura should be responsible for the repair. I expect to be reimbursed by Acura.

Low beam headlights becoming more and more dim over time. The cause is alleged to be degradation of the bulb reflector surface.

While driving normally on Veterans Pkwy, my moonroof exploded. I thought sometime must have thrown something at my car while driving, or I got hit by a meteorite. My shade was open so I could see that the glass was shattered and had a hole in the middle about the size of a large potato. It was 11/3/26 at 3:45 pm cst. It has been raining for a few days.

The HID headlights have had the reflector coating fail and the debris has deposited on the back side of the lens where it is inaccessible so can not be removed and has effetely blocked most of the light from exiting the lens. This is a known issue and Honda/Acura has chosen to ignore a fix to the problem. This has been progressively getting worse and new bulbs have not corrected the situation.

I have experienced the following situations while driving: •At night, drivers approaching from the opposite direction signal me to turn on my headlights, even though my headlights are already on. •In rainy conditions, I often have to pull over because I cannot adequately see the road markings. •Recently, while driving on neighborhood streets lined with mature trees, I failed to see a curb and struck it because of the limited visibility. My vehicle's history shows that an Acura dealership replaced the headlight bulbs in 2020, at approximately 77,000 miles, slightly beyond the basic warranty period. Since then, I have replaced both low-beam bulbs again in 2026. My exterior headlight lenses are clear, and replacing both bulbs has not resolved the problem. In October 2026, Acura dealership inspected my vehicle. The dealership documented that both headlight bulbs were operating properly and that the electrical output was proper at 12V. The dealership recommended replacing both headlight assemblies due to cloudiness inside the headlight lenses resulting from moisture/oxidation. The dealership also documented that it could not perform photometric output testing because it lacked the appropriate equipment. The dealership quoted $4,652 for the replacement of headlight assemblies. A vehicle should not develop severely inadequate headlight illumination to the point that it becomes dangerous to drive at night simply because of its age or mileage. As a family vehicle, I regularly drive with my child as a passenger. At this point, this is a severe safety hazard to my family and other people on the road.

My 2015 Acura RDX Technology package has been having very dim headlights. I have replaced the bulbs in the car which provided no remedy. I then had the bulbs replaced with LED lights which are more bright than the original lights with no remedy. The danger is to me and the occupants of the vehicle as you can not see more than 5-10 feet in front of the car. In addition, other cars or pedestrians on the road, I can not see them because of these issues will pose a serious safety risk to not my occupants but to others on the road. I have had the car inspected by my mechanic and we tried the different lights to improve the vision of the lights. The car has not provided any errors on the dashboard, or "engine warning light". I would like to lodge this complaint against Honda, Parent Company of Acura, to see if there is a resolution to the problem. This is currently still happening on my vehicle.

The low beam headlights are very dim at night time. An extreme safety issue. I had to occasionally use the high beam headlamps for proper visibility. I had the bulbs replaced and the brightness did not improve at all. I spoke with the service department at the dealership where I purchased the vehicle and was advised that the headlamp assemblies need replacing. I replaced them at a significant cost.
