Oct 18, 2024Visibility & wipers

The windshield wipers do not work. When the wipers are turned on, the spray comes on and does not turn off. You are unable to see as the spray keeps spraying the entire time the wipers are on. I took the dealer twice and they have been unable to repair. They now say are waiting for parts. I can't be the only one. This is very concerning. Luckily I live in Las Vegas and we have little rain. What component or system failed or malfunctioned, and is it available for inspection upon request? wipers and yes How was your safety or the safety of others put at risk? You literally can't see if you use the wipers. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes been to service twice. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The Dealer only. GM does not seem to care. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning. I turned on wipers when it was raining. Luckily I was close to home. You cant see. Super dangerous.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 GMC Hummer EV SUV verdict →
