"Tesla identified an issue with the light bar's adhesion to glass back in February and worked for months to find a solution. In October, the company performed chemical testing as a part of an engineering study and determined the root cause as the BetaPrime primer it utilized, figuring out that it was not the right surface priming material to use for this specific application."
"At no charge to customers, Tesla will inspect the service-installed optional off-road light bar accessory for delamination or damage and if either is present, replace the light bar with a new light bar adhered with tape and a positive mechanical attachment. If no delamination or damage is present, Tesla will retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment."
Tesla recalled 6,197 Cybertrucks for a service-installed aftermarket off-road light bar that may have been attached with the incorrect surface primer, causing adhesion problems to the windshield. The company identified adhesion issues in February, conducted chemical testing in October, and determined the BetaPrime primer was not suitable for this application. The component is manufactured by Hella Romania S.R.L., and the problem is the primer choice rather than primer quality. Tesla reported 619 warranty claims and one field report, with no injuries or deaths. Tesla will inspect affected light bars at no charge, replace damaged units, or retrofit them with a positive mechanical attachment.
