I had to replace a battery in my 2015 RLX this seemed expensive and excessive given what I paid for this vehicle I was just over the warranty mileage at 87000 km. I have an Acura extended warranty but the battery not covered. The warning I got from the car was that keyless system my not work contact your dealer ASP. They replaced the battery and still getting the warning. The vehicle did sit prior to this in cold weather and had to be jump started because the battery did go dead still seem a bit much fo a 2015 RLX. I was also charged for the diagnostic even though replacing the battery did not solove the warning being sent by the car. Any comments?
