If you were to look through the recall notices on the National Highway Traffic Safety Administration website about the 2014-2015 Chevrolet Equinox and GMC Terrain, you would come across a pretty normal looking recall. A new report, though, suggests that although the repair for this problem should be simple, some vehicles are going unfixed because of parts shortages.

Speaking to WAVY.com, Smithfield, Virginia’s John Wayne Warren said that he received a letter about his 2015 GMC Terrain telling him that, although it and 681,508 other vehicles were under recall over faulty windscreen wipers, it will not be fixed for the time being.

“Parts to repair your vehicle are not currently available, but when parts are available, your GMC dealer will inspect the wiper module and repair or replace it as necessary,” the recall notice stated. “This service will be performed for you at no charge.”

That’s a problem for Warren, whose car became afflicted by the problem shortly after receiving his letter. Like others, his Terrain’s windshield wiper module ball joints experienced corrosion that caused the wipers to fail.

“My fiancée was going down the road in heavy rain, and the wipers stopped working. She had to pull over and wait for the rain to stop,” said Warren, adding that he now has to keep an eye on the weather whenever he goes for a drive.

He said that he has corresponded over email, text, and the phone about his GMC dealership, but no solution has been offered. Warren’s other option is to pay for the repair himself, likely from a third-party garage, but that would cost about $1,000, making it unappealing when it should be done for free.

GMC maintains, though, that it simply doesn’t have the parts to complete the repairs: “We have announced the recall, but we are not executing it because we need to have our suppliers build the parts to begin repairs. We apologize for any inconvenience. We understand concerns and frustration.”

Time is ticking for Warren, though, whose car has an annual inspection to complete in August that he expects to fail without working windshield wipers. That is, understandably, frustrating to him.

“This is total insanity in my opinion,” he said.
