Frequently Asked Questions
Can I drive with code U0158?
Yes. The head-up display is a convenience feature only. All driving information is still available on the main instrument cluster.
Can windshield replacement cause U0158?
If the windshield was replaced with glass that is not HUD-compatible, the HUD projection may not work correctly. HUD-equipped vehicles require a special laminated windshield with an anti-reflective coating in the HUD projection area.
Is HUD repair expensive?
HUD module replacement can cost $200 to $1500. The projector unit is located on top of the dashboard and requires careful removal. Some vehicles also need programming after replacement.
