There are 6 owner-reported electrical system complaints for the 2015 Acura RDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Common problem with this year and model is the low beam projector headlight assembly dims. This is a huge hazard and makes it impossible to see at night with low beam lights. I cannot see more than 30 feet in front of the vehicle at night making the reaction time to any potential threat non-existent at freeway speed and severely reduced in neighborhoods. All options investigated are to replace assembly, not lightbulb. This is a manufacturer fault and cost should be bourn by the manufacturer. Same problem with the RLX and Acura voluntarily recalled those headlights for replacement. They should be required to do the same for these.
Headlights Due to the lack of brightness and deterioration over time, the driver is left with a lack of visibility. UNKNOWN if reproduced. No inspections. No warnings or messages.
Drove vehicle home during daylight. At nite the low-beam lights are useless high-beam needed to be able to see. Carfax was unaware of a "safety recall" for this problem. I found numerous complaints about this on the web. There needs to be a "recall" to get this corrected. Should be addressed by mfg and not consumer.
The Keyless Entry TPMS controller in the car, part #38320-TX4-Ao1 malfunctions, and the care does not turn itself off. The engine normally stops, but electrical systems continue operating and the car will drain its battery with a few hours. This is not an isolated occurance, while dealership personnel have not given firm #s, I beleive this may be effecting as high as 20% of the vehicles with this part. We have had a replacement part on back order since August 30th of 2023, today the dealship told me we are elevated to Urgent Backorder with not estimated fulfillment. On service tech told me the issue is that Acura suspended manufacture of the part as they try to solve this issue.
An electrical keyless part in the vehicle drains the battery causing it to stall wherever or whenever you are on the road. It has been confirmed by the dealer(Courtesy Acura) that the vehicle needs a new part that they are unable to manufacture in a timely manner. It has been almost a year since the incident, and Honda is still not supporting a product that was faulty the day the car rolled off the assembly line. I was told by a representative of Honda that my car, 2015 Acura RDX, is the only vehicle with that VIN number to have this problem, and I know that not to be true.
SOMETHING IS DRAINING THE BATTERY, KEEP HAVING TO JUMPSTART IT AND STALLS SOMETIMES WHEN DRIVING. BATTERY PASS AS GOOD. I DID RESEARCH ON IT AND A LOT OF COMPLAINTS ABOUT IT.
