What Does a CSI Score Actually Measure?
CSI stands for Customer Satisfaction Index. OEMs use it to measure how satisfied customers are with their sales or service experience at a specific dealership. Scores are typically compiled from post-visit surveys - sent by the OEM, not the dealership - and they directly affect dealer bonus payments, incentive eligibility, and in some cases, vehicle allocation.
The scoring scale varies by manufacturer. Ford uses a 0–10 scale. GM uses a percentage satisfaction format. Toyota and Lexus use a 'completely satisfied' measure as a binary outcome. Honda and Acura track 'top box' scores - the percentage of customers who give the highest possible rating. Comparing raw scores across brands without knowing the methodology will give you the wrong picture.
What Is a Good CSI Score by OEM?
Rather than fixed numbers, OEMs benchmark dealers against their regional or national average. Here's what 'good' looks like across the major brands: For Toyota and Lexus, a 'completely satisfied' rate above 92% typically places you in the top performance tier. For Ford, a score of 8.5/10 or above on service satisfaction is generally competitive. For GM, a 'satisfied or completely satisfied' rate of 90%+ is the target for bonus eligibility. For Honda and Acura, top-box scores above 85% are competitive in most regions.
The key insight: OEMs don't reward you for being average. Bonus structures are typically tiered - the top 25% of dealers get the full incentive, and scores below the regional median can trigger performance improvement requirements. 'Good' means above the 75th percentile in your region, whatever number that corresponds to in a given quarter.

What Is the Relationship Between CSI Score and Google Rating?
Your OEM CSI score and your Google rating measure related but different things. OEM CSI surveys reach customers who completed a transaction - a service visit or vehicle purchase. Google reviews capture anyone who had an experience, positive or negative, including customers who felt strongly enough about a bad experience to post publicly without being asked.
In practice, dealerships with CSI scores in the top quartile tend to have Google ratings above 4.6. Dealerships with CSI scores in the bottom quartile tend to cluster around 4.0–4.3. The correlation exists because the underlying driver is the same: whether customers leave feeling resolved or unresolved. Dealers who catch and address dissatisfied customers before the survey - through proactive follow-up - see improvement in both metrics simultaneously.
What Is the Financial Impact of a CSI Score Drop?
The most concrete number: a 1-point drop in your OEM CSI ranking - moving from the 75th percentile to the 50th, for example - can cost $15,000–$40,000 in annual OEM bonus payments, depending on your brand and volume. For high-volume dealers running 1,000+ repair orders per month, the impact can be higher.
There's also a compounding effect. A lower CSI score reduces eligibility for floor plan incentives, vehicle allocation priority, and co-op advertising support at some OEMs. It also makes recruitment harder - high-performing employees prefer stores with good ratings, and your Google score is often the first thing a candidate checks.
How Do You Improve CSI Score Consistently?
The single most reliable lever for CSI improvement is contact rate - the percentage of service customers you actually reach for feedback before the OEM survey arrives. A customer who felt their wait was too long, their invoice was confusing, or their advisor was dismissive will file a negative survey if nobody calls. The same customer, reached within 24 hours by someone who acknowledges their concern and offers resolution, frequently gives a higher rating or withdraws the negative response entirely.
Manual BDC follow-up rarely achieves above 30% contact rate at any sustainable volume. Dealers using automated post-service follow-up - calling every repair order customer within 24 hours - consistently achieve 65–75% contact rates, and see CSI score improvements of 15–20 points within 90 days. World Hyundai Matteson went from a 4.0 to a 4.8 Google rating in 8 weeks using this approach.
Bottom Line
A good CSI score is one that keeps you in the top quartile of your OEM's regional ranking - which typically means a 'completely satisfied' or 'top box' rate of 88–93% depending on your brand. The number matters less than the percentile. And the most direct path to improving that percentile is ensuring every service customer hears from you before the OEM survey does.
