New 2025-2026 call tracking and shopper research puts real numbers on service-call miss rates. Here is how to turn those benchmarks into your own store's number.
Most dealership leaders have a rough sense that missed calls cost money. Few have a number. That gap matters, because "we probably miss some calls" doesn't get budget approved and doesn't change staffing decisions. A number does.
2025 and early 2026 brought enough call-tracking and shopper-research data to build that number honestly, without guessing. Here is what the data actually says, and how to turn it into a figure specific to your store.
Car Wars, which tracks call activity across dealership phone lines nationally, analyzed roughly 53 million inbound service calls in 2025 and found that the average dealership connected a live person on about 65% of them. Put differently, close to one in three service callers never reached anyone (CBT News).
Of the calls that didn't connect, 53% ended up in voicemail and another 29% were abandoned after the caller sat on hold too long (CBT News). Most service drive reporting doesn't count either one as a lost customer, so nobody notices the pattern unless they go looking for it.
That miss rate isn't evenly distributed. Call volume peaks between 10 a.m. and noon, the same stretch when advisors are heads-down writing up the customers already standing at the counter (CBT News). The calls a store is least equipped to answer are, structurally, the busiest ones.
The miss rate matters more once you account for how much service revenue still moves through the phone rather than a website form or app.
CDK's Service Shopper research found that 64% of service customers call ahead to book an appointment, compared with 19% who book online (CDK Global). That's the primary front door for fixed ops, not a legacy habit customers are abandoning for apps and web forms.
The same research found that 40% of those callers ran into friction while trying to book: long hold times, transfers, or navigating a phone menu, with average hold time sitting at 8.2 minutes for service calls (CDK Global). CDK also found that hold time alone has a measurable effect on Net Promoter Score, a 19-point swing between customers who waited and customers who didn't (CDK Global).
So the two numbers stack: most service business still comes in by phone, and a third of that inbound volume either doesn't connect at all or connects only after enough friction to move the customer's opinion of the store.
Harvard Business Review's research on speed to lead found that companies contacting a prospect quickly were far more likely to have a substantive conversation than companies that took longer (Harvard Business Review). That research covered digital sales leads, but the underlying mechanic applies to any inbound call: intent decays the longer it sits unanswered.
A missed service call rarely disappears. It usually turns into one of three outcomes: the customer calls back later and the store gets a second chance, the customer calls a competing shop, or the customer defers the visit and the vehicle goes longer without service. None of those are neutral for the dealership. Cox Automotive's Fixed Operations and Ownership Study has tracked declining rates of owners returning to their selling dealership for service, with friction around access and responsiveness cited as a factor (Cox Automotive). A missed call is one of the more avoidable forms of that friction.
Industry averages are a useful starting point, but the number that actually justifies a decision is your own. The math only needs three inputs, and most stores already have all three or can pull them from a week of call logs.
First, your inbound service call volume, pulled from your phone system or call-tracking platform for a typical month. Second, your connect rate: what share of those calls reach a live person versus voicemail, abandonment, or a dropped transfer. If you don't already track this, a week of manually reviewing call logs will get you close enough to start. Third, your average repair order value. NADA's mid-year 2025 data puts the industry average customer-pay repair order at $470 (NADA), but your own number, pulled straight from your DMS, will beat any industry average.
The formula: missed calls per month times the share of missed callers who would have booked, times average repair order value, times 12. Even a conservative booking-rate assumption, run against a 25-35% miss rate on real call volume, tends to land in the low six figures annually for a single-rooftop store. Run it with your own inputs before deciding whether that number is worth acting on.
Do the math even if your own figure comes in lower than the industry range. A store that knows its connect rate has something to improve against. A store that doesn't is just guessing.
None of this is an argument that dealerships are badly run. Service departments are staffed for the customers standing in front of advisors, which is the correct priority. The problem is structural: the same 10 a.m. to noon window that fills the drive is the window that generates the most inbound calls, and there's no way to staff a phone desk for a peak that overlaps with peak in-person volume without adding headcount that sits idle the rest of the day.
That's the actual decision in front of most GMs and fixed ops directors right now: add phone coverage that scales with call volume without adding a body to the schedule, or keep absorbing a miss rate that industry data puts at roughly one in three. One dealership's 30-day numbers after closing that gap are a useful reference point once you've run your own math.
