The 2003 GMC Envoy has 5 recalls, the most serious involving a scored left-front brake pipe that can fracture and cause an immediate drop in braking power, raising the risk of a crash.
Two recalls address turn signal malfunctions: in one, the turn signals or hazard lights illuminate but stay solid instead of flashing, and in another, activating a turn signal causes all four corners to flash like hazard lights rather than indicating only one side. Both conditions can make it difficult for other drivers to read your intentions on the road. The windshield wiper system can also fail due to water getting into the wiper module, causing the wipers to stop working, refuse to turn off, or run the washer pump continuously, which can leave the driver with reduced visibility in wet conditions. The final recall is a compliance issue with the transmission: a mechanical override can allow the ignition key to be removed while the shifter is not in Park, which can leave the vehicle able to roll.

What can fail
Water enters the windshield wiper module and causes short circuits or corroded components, preventing wipers from turning on, stopping unexpectedly, failing to respond to controls, or running the washer pump continuously.
What the fix does
Dealers will seal the wiper module vent hole and inspect the wiper motor, circuit board, and connector for water damage or corrosion, replacing parts as needed.

What can fail
The left-front brake pipe has a groove scored into it during manufacturing. If this pipe cracks or breaks, the brake pedal will travel farther and front braking power will decrease.
What the fix does
Dealers will replace the left-front brake pipe at no charge. Contact your brand's customer service if service is not completed within a reasonable time.

What can fail
The ignition key can be removed when the shift lever is not in Park, and the transmission can be shifted out of Park when the ignition is off. These mechanical overrides bypass theft protection.
What the fix does
Dealers will disable both overrides to restore proper ignition and transmission controls.
