Depends on where it hit. Utilities aren't immune to disruption via indirect hits. A comm center had at least one, usually two entrances into the main. They aggregate via the sub street conduits. Usually they're placed two to four feet below grade.
The cabling is either old lead sheathed copper cables or modern polymer fiber. Old lead can snap open with a shock as lead is malleable but doesn't like to be moved suddenly. Fiber optics in a splice can be severed if snapped hard enough.
An explosion which disrupts some service can cause further disruption as splices and cabling are moved around the facilitate further work.
If everything is done perfectly to spec, catastrophe is minimized by such but there's no guarantee workers properly secured the splice points, left enough slack, or secured cabling in the vault.
This doesn't even get into commercial power issues due to transmission failures.
I'm hardly shocked that a car bomb could cause an issue.
