Halloween is the single worst night of the year for pedestrian visibility, and most of it happens at dusk in residential streets. Here is what to actually look at, using a 2022-2024 GMC Hummer EV as the example.
Body and Exterior
Watch for a mirror that shakes at highway speed after a folding motor fails. Not a scheduled item. These are damage and failure replacements.
Mirrors carry cameras, heaters, turn signals, blind zone modules and puddle lamps, and the wiring connector varies by content level.
Glass and Wipers
Watch for wipers that park in the wrong position. Blades every six to twelve months. In North Texas, summer heat kills blades faster than winter does.
Windshields with acoustic interlayer, HUD or camera brackets are not interchangeable with base glass.
Sensors, Cameras and Driver Assistance
Watch for a backup camera image that flickers, goes blue, or shows lines. TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.
TPMS sensors have to match the protocol and frequency the receiver expects.
The Short Checklist
- Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
- Wiper blades: Driver and passenger blades are frequently different lengths on the same vehicle.
- Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
We are a factory GM dealer, not a reseller, so what you order is the same part the service drive installs. Browse our GMC OEM parts catalog or search for Hummer EV parts.
