Example complaints

“The air conditioner blows out only warm air. I have taken it to the dealership and they have diagnosed the problem as a faulty compressor and have ordered a new part but it is on a national backorder with no eta for the part. It is unacceptable that Acura is ignoring a wide spread problem and not issuing a recall or product update for the affected models.”
