Over-the-air updates help manufacturers fix bugs quickly, but they can also create temporary issues.

Possible OTA update concerns include:

• Failed software installations
• Temporary feature loss
• Battery drain during updates
• Sensor recalibration problems
• Connectivity interruptions

The automotive industry still treats software updates like a balancing act on a tightrope. One small mistake can create unexpected chaos.
