The 2027 Chevrolet Bolt is facing another quality concern, this time involving a rattling sound near the windshield. General Motors has issued a service bulletin outlining a simple fix for the all-electric subcompact crossover, while NHTSA has not issued a recall for the problem.
What Causes the Chevrolet Bolt Rattle?
GM Service Bulletin #26-NA-201, reported by GM Authority, instructs dealerships and technicians on how to address the issue.
The rattle comes from an insert inside the windshield multifunction sensor mount bracket cover located behind the rearview mirror. The sound can occur when the Bolt travels over bumps and is not limited to a particular speed.
The issue appears to be a fit-and-finish or NVH concern rather than a mechanical or electrical failure.
How GM Plans to Fix the Problem
The repair does not require a complicated procedure. Technicians will first inspect the insert and the area around the rearview mirror for loose parts.
If the insert is loose, it will be removed. Technicians will then add two small pieces of felt/flocking tape to the forward tabs.
Each piece measures 6.5 mm by 6.5 mm (0.25 inches by 0.25 inches) and is 1 mm (0.04 inches) thick. After installing the tape, technicians will reinstall the components and verify that the rattling sound is gone.
Chevrolet Bolt Has One Recall So Far
The latest issue follows a recent concern involving a taillight leak, but the new rattling problem has not resulted in a recall from NHTSA.
The returning Bolt nameplate currently has one recall. Under NHTSA recall 26V114, the radios in 117 affected Bolts may not have been configured correctly to download the electronic owner’s manual.
That issue could cause the affected vehicles to fail to comply with FMVSS No. 208 (Occupant Crash Protection).
2027 Chevrolet Bolt Production Is Expected to End Soon
Production of the 2027 Chevrolet Bolt began in late 2025 at Fairfax Assembly in Kansas. GM plans a relatively short production run, with Bolt production expected to end in the first quarter of 2027 as the plant prepares for other vehicles.
Those vehicles include the combustion-powered Equinox, which is currently built in Mexico, as well as a next-generation Buick compact SUV.
2027 Bolt Starts Below $30,000
The limited production run comes as the U.S. market needs more affordable EVs. The 2027 Chevrolet Bolt starts at $27,600 before destination charges, putting it in the same sub-$30,000 EV category as the Nissan Leaf based on MSRP.
The Bolt has long been considered a temporary product, but its short production run does not make manufacturing quality any less important. Even a minor issue such as a rattling component can create an inconvenience for owners.
