Think of the most unpleasant waiting room situations you can imagine: the DMV, an after-hours urgent care clinic, or the head-shrinking purgatory in the original Beetlejuice movie.

A viral social media post makes a strong case that an auto dealership service department should join that list, thanks to the frustrating process of updating software on most modern cars.

The TikTok from EliteVoiceTV (@elitevoicetv) starts with the reasonable assumption that downloading some files, drivers, and apps should take about 30 minutes and can be completed during lunch hour. We’re quickly disabused of that notion and warned that an update can take hours—or even the better part of a day.

"All these new updates, all this new software, all this stuff is not a quick thing. We're not downloading music. This ain't Limewire," the narrator informs us with legit outrage and disbelief. "Make sure you bring breakfast, lunch, and dinner, and snack, 'cause you're gonna be sitting there. It's not that quick. I'm sorry."

It is true that a software update could take half a day or more. But the reality is that modern cars contain a complex patchwork of computers and software systems, with dozens of control modules handling everything from the infotainment system and driver assistance to battery health, transmissions, and climate controls.

And updating to a single system often means updating several other connected systems in a precise sequence, all of which require checks along the way to ensure no disruptions occur. Over-the-air updates are becoming more common, but most in-house software updates still require the car to be connected to a dealer's diagnostic equipment and kept undisturbed until the process is complete.

The comment section of the clip quickly filled up with waiting room war stories. One viewer said that a four-hour update escalated into a multi-day problem: "Yep 0.3 (hours) to do a 4-hour update that then bricks the control unit. Now car is stuck in the bay for 2 days for new control unit to come in."

One frustrated technician shared an especially brutal example, writing, "Transmission update took overnight for one of the cars we did. 12+ hours over the internet. It didn't even give us a time frame. Thing kept jumping around."

Why Do Updates Take So Long?

The frustrated narrator offers a brief explanation for why these updates are so maddening and hard to predict. They say the seemingly simple update process actually involves a series of steps that start with downloading the software from the manufacturer's servers, unpacking and installing it, and running validation checks.

And any improper installation glitches can mean repeating parts of that cycle, sometimes more than once.

There's also the plain problem of network conditions and bandwidth. Speeds can fluctuate wildly at a busy dealership, pulling multiple updates on multiple vehicles at once. Some systems pause or restart if the connection hiccups or glitches, which is why progress indicators can stall or even move backwards.

Add in the wrinkle that vehicles that look identical on paper can behave very differently in practice depending on their existing software versions and hardware combinations.

How Do Technicians Feel About Updates?

It's also worth remembering that, unlike a phone or tablet, a software glitch in an automobile can have serious side effects.

If a critical module stops responding, a car might be unable to start, shift, charge, or communicate with other onboard systems. At that point, the fix often isn't a simple retry, and some modules can't be rolled back once an update begins since recovery may require hardware replacement rather than just more software.

The video also presents the no-win situation service departments can face when handling software updates and why technicians approach them with a mix of veteran patience and quiet dread. A car stuck in update limbo doesn't just inconvenience its owner; it also occupies a service bay for an indeterminate period, tying up diagnostic equipment and slowing down workflow that depends on steady turnover.

In flat-rate shops, it also creates a painful misalignment between the actual time used versus the standard paid time from manufacturers, since warranty labor allowances often don't reflect how long procedures actually take. If you're a technician, think of it as being stuck staring at a progress screen, waiting and silently begging for progress while the music from Final Jeopardy plays in your head over and over and over.

Given all this, drivers can reduce their potential pain by not waiting at the shop for major software updates unless explicitly told it'll be a short process. You can also ask whether an update is safety critical or optional, and whether it can be scheduled overnight. Make sure your battery is healthy before taking the vehicle in for an update, as low voltage can disrupt the update and add to wait time.
