How to Improve Dealership Service Retention, Backed by Data

Last updated: October 16, 2026

Quick answer: To improve service retention, give customers a reason to come back and make the visit easy. Across 871 dealerships in our Cost of Silence report, strict 12-month retention was 65.8%, below NADA's 72% target. Customers with a text conversation on their RO came back about 6 points more often. Campaign recipients came back 9 to 10 points more often, and customers given a loaner about 7 points more.

What is a good service retention rate for a dealership?

NADA's target is 72% year over year. Most stores sit below it.

In our Cost of Silence report, we looked at 871 dealerships and 16.8 million repair orders over 12 months. On a strict cohort basis, retention was 65.8%. Counting reactivated customers, the ones who came back after a long gap, it rose to 73.9%.²

Brand averages are lower. The report puts domestic brands at about 55% and imports at about 60%.² So if your store is at 60%, you're normal. Normal isn't the goal.

That 8-point spread between 65.8% and 73.9% is customers who lapsed and then came back. Outreach is how you get more of them.

How do you calculate your service retention rate?

Take the customers who had a paid service visit in one 12-month period. Count how many came back for service in the next 12 months. Divide the second number by the first.

Service retention rate = customers who came back ÷ customers from the earlier period × 100

Say 2,000 customers came in last year and 1,300 of them came back this year. Your retention is 65%.

A few things will change your number, so pick a method and stick with it:

• Count unique customers or unique VINs, not ROs
• Decide whether warranty-only and internal ROs count
• Track a strict number and a number that includes reactivated customers, separately
• Use the same window every time you compare, or your trend means nothing

Your OEM may calculate it differently. That's fine. Just know which number you're looking at before you set a goal.

Why does service, not sales, keep customers coming back?

Because that's where you see the customer. You might sell someone a car every few years. You'll see them in your service lane a couple of times a year.

Every one of those visits is a vote. A fixed car with poor communication can still lose you the customer. A small job handled with care and a clear price can keep them for years, and keep them in mind when it's time to trade in.

So the question isn't whether your techs do good work. It's whether the customer felt informed and respected while they did it.

What actually moves service retention?

Three things showed up clearly in our data. Customers with a digital conversation on their RO had retention about 6 points higher. Customers who received a campaign came back 9 to 10 points more often. Customers given a loaner came back about 7 points more often. Each group had more than 20,000 customers.²

Is all of that caused by the texts and the loaners? Probably not. Customers who reply to texts may already be more engaged with your store. These are correlations, not controlled tests. But the direction is the same across all three, and most stores aren't doing them consistently.

Talk to customers in the channel they want

76.3% of repair orders still close with no digital conversation.² That's a lot of customers who only hear from you by phone, if at all.

Ask every customer how they want to be reached at write-up. Then use that channel. If they asked for a text, don't call them at 5 PM to say the car is ready. Keep it all in one thread. Your advisor and techs can talk inside it without the customer seeing the back-and-forth.

Reach out between visits

Campaigns had the biggest lift in our data. Maintenance reminders, recalls, declined work and seasonal work all give the customer a reason to book. Across the platform, campaigns booked 154,003 appointments and drove $50.5 million in attributed service revenue.²

Appointment confirmations count too. They cut no-shows and save your BDC a lot of dialing. Honda & Toyota of Seattle saves 160 hours a month on appointment confirmations alone.

Hand them a loaner when the job is long

A customer without a car for two days remembers it. A loaner takes that pain away, and customers given one came back about 7 points more often.²

The catch is the fleet itself. Paper contracts and missed fees make loaners expensive. With Kimoby Go, contracts and fees are digital. Policaro BMW recovered $688.75 in loaner fees in the first week.

How do you win back customers who stopped coming in?

Find them in your DMS, then give them one specific reason to come back. Customers with no visit in 12 months or more are your list.

They're worth the effort. A customer returning after 13 months or more spent $549.28 on that visit, against $320.76 on every other RO.² Reactivated customers made up 1% to 7% of RO volume, depending on the store. A typical store sits around 4%.

A specific reason works better than a generic "we miss you." The brake job they passed on last time is a good one. Here's how to follow up on declined service without sounding pushy. If you want the full numbers behind lost customers, read Your Service Customers Are Already Leaving.

What else keeps service customers coming back?

The basics, done every time. Here's where we'd look next.

Show the work and the price up front

Fear of being overcharged keeps people away from dealer service. Show them the problem. 64% of service customers want a photo or video with their inspection, but only 26% of mass-market customers get one (J.D. Power, 2026).¹ Send the estimate to their phone with the video. The median digital approval in our data was 6 minutes.² Our video MPI guide covers the workflow.

Consider posting prices for common jobs on your website, like oil changes and tire swaps. No surprises at the counter.

Fix it right the first time

A comeback for the same problem undoes every good text you sent. Good diagnostics and parts on hand before the car hits the bay matter more here than any retention software.

Check in after the visit

A short text after pickup asks how it went. Unhappy replies get flagged, so your manager can call before the OEM survey arrives. More on CSI surveys.

Make paying easy

Only 4.7% of repair orders get a digital payment request today.² That's why there's a line at the cashier at 5 PM. Let the customer pay by text before they arrive, and the last thing they remember is a quick pickup.

Where does Kimoby fit, and where doesn't it?

We make Kimoby, so take this with the right amount of salt.

With Kimoby, your advisors text customers from your dealership's number, send video inspections and estimates, and take payment in the same thread. Your team builds campaigns from DMS data, and your loaner fleet runs on Kimoby Go. It sits on top of the DMS you already have, and more than 1,000 dealerships across North America have used it.

What it doesn't do yet. There's no native online scheduler, so most stores keep the one they have. Kimoby Voice catches missed calls and lets callers switch to text, but it doesn't book appointments yet. Payment write-back to the RO works on CDK only for now.

If that works for your store, book a demo. Bring your current retention number and we'll show you where the campaigns would start.
