What Happened
Your vehicle's air suspension system is controlled by a computer called the PCM. Sometimes, this system can send a brief electrical surge while you're driving, which could mess with the PCM's signals.
Risk if Unfixed
If this surge damages the PCM, your vehicle might not restart, and if this happens while you're moving, you won't get any warning before a potential crash.
Free Fix
Your authorized Oldsmobile or GMC dealer will install a special wiring harness to prevent this issue, and the repair is free. You should contact them at 1-800-630-6537 or 1-866-996-9463 to schedule the repair when it's time.
