A Little Shaken
After recently dealing with a taillight leak concern, the 2027 Chevrolet Bolt is back in the news with another issue. This time, the all-electric subcompact crossover may develop a rattling sound near the windshield, though it appears to be a minor quality concern, especially since NHTSA has not issued a recall.
Instead, General Motors has issued Service Bulletin #26-NA-201, as reported by GM Authority, which essentially instructs dealerships and technicians on how to fix the problem. The rattling sound stems from an insert inside the windshield multifunction sensor mount bracket cover located behind the rearview mirror. It can occur when the EV drives over bumps and isn’t limited to a particular speed.

No Wrench Required
The fix is simple. Technicians will inspect the insert and the area around the rearview mirror for loose parts. If the insert is loose, it will be removed before two tiny pieces of felt/flocking tape – each measuring 6.5 mm x 6.5 mm (0.25 inches x 0.25 inches) and 1 mm (0.04 inches) thick – are added to the forward tabs.
Once that is done, technicians will reinstall everything and verify the rattle is gone.
This appears to be a fit-and-finish or NVH issue rather than a mechanical or electrical failure. So far, the returning nameplate shows a recall count of just one. Under NHTSA recall 26V114, the radios in 117 affected Bolts may not have been configured correctly to download the electronic owner’s manual, causing the vehicles to fail to comply with FMVSS No. 208 (Occupant Crash Protection).

A Short Run With Loose Ends
Production began in late 2025 at Fairfax Assembly in Kansas. However, GM plans only a relatively short production run, with Bolt production expected to end in the first quarter of 2027 as the plant prepares for other vehicles, including the combustion-powered Equinox – currently built in Mexico – and a next-generation Buick compact SUV.
Such a short-lived run is debatable, given that the U.S. market needs more affordable EVs. The 2027 Bolt starts at $27,600, excluding destination charges, putting it in the same sub-$30,000 EV category as the Nissan Leaf MSRP-wise. It has always been considered a temporary product, but that doesn’t make manufacturing quality any less important, especially since even minor issues can be a hassle to deal with.
