The national estimate is adjusted by your state's overall price level (BEA Regional Price Parities, 2022, U.S.=100). This is a cost-of-living proxy applied to the national serpentine belt repair price — not a per-state serpentine belt repair quote.
Check your estimate against 182 NHTSA owner complaints

This page is for owners pricing a serpentine belt job or deciding whether a squeal can wait. Below the calculator, 182 NHTSA owner complaints show which models reported belt failures, at what mileage and speed, and which parts failed with the belt: the alternator in 39 reports and power steering in 38.
A serpentine belt replacement costs $85–$173 at a shop with an aftermarket belt ($15–$80 plus labor), or $40–$100 in parts if you do it yourself. Adding a tensioner kit raises the estimate to $145–$323, and the largest vehicle types reach $125–$273.
Low mileage does not mean the belt is safe. In 182 NHTSA owner complaints, 49% of failures happened under 50,000 miles, and 21% of the reports also named the alternator.
What owners reported to NHTSA about the serpentine belt
“Took to dealer and was advised the car requires CVVTS (which is essentially a new engine), serpentine belt and spark plugs (approx $3600).”
“The serpentine belt was busted, info on it says it should 5 years or 100k miles.”
“About 70,000 miles, bearings on the idler pulley and tensioner on serpentine belt failed.”
Owners also checked on the NHTSA form: 2 crashes, 5 fires and 2injuries. A report does not always say the serpentine belt caused it.

Everything owners described with the serpentine belt
5 manufacturer service bulletins mention the serpentine belt
Service bulletins (TSBs) are the automaker's repair instructions for a known issue, filed with NHTSA. A bulletin is not a recall and does not mean every vehicle has the problem; it can mean a known fix, updated part or extended coverage. Ask the shop whether one applies to your VIN.
| Bulletin | Vehicles | What it covers |
|---|---|---|

Odometer spread across 55 serpentine belt complaints
Median odometer by model year: 2015: 57,505 mi (16 reports) · 2017: 42,000 mi (11 reports). Newer model years have had less time to rack up miles, so their medians run lower.
This is the mileage owners reported when they filed, not a failure probability.

What this page's numbers are based on, and what they leave out
- 182 NHTSA owner complaints naming the serpentine belt (2015–2025 models).
- 0 NHTSA recall campaigns and 5 manufacturer service bulletins that mention this part.
- The calculator's estimate: typical labor hours and parts ranges for this job, adjusted by state using government wage and price-level data.
- 111 complaints mention a dealer and 20 an independent shop.
- Not included: a quote for your exact vehicle, diagnostic fees, taxes, dealer markup, or secondary damage (for example engine damage after overheating). Owner-reported amounts often include those extras, which is why they run higher than the calculator.
More of what owners told NHTSA
“July 21, 2024 On June 1, 2024, while driving at normal speed under normal conditions, 2020 Chrysler Pacifica (with 14,600 miles) engine seized up, serpentine belt tore, power steering lost, and all lights went on within seconds.”
“Vehicle is a 2023 Mazda CX-5 Signature Turbo model that had a leaking hydraulic tensioner for the serpentine belt at 15,759 miles.”
“While driving at highway speed, the factory-installed serpentine belt on my 2023 Chevrolet Express 3500 (6.6L V8, approximately 24,000 miles, purchased new, factory-maintained per schedule) failed suddenly and without warning.”

Infiniti Q50 and Honda CR-V owners report serpentine belt failures well before typical replacement mileage
On the Infiniti Q50, owner complaints put the median failure at 23,000 miles, with most reports on 2017 and 2018 models. On the Honda CR-V, the median is 38,000 miles, with reports peaking on 2015–2017 models. A 2015 CR-V owner told NHTSA: "The serpentine belt was busted, info on it says it should 5 years or 100K miles."
For owners of either car, the service schedule will not flag the belt this early. If you hear squealing or see a charging warning at these mileages, have the belt checked. The belt alone is the lowest line on the calculator: $70–$133 for the smallest vehicle class.
Serpentine belt complaints list engine damage 20 times: a snapped belt can cost more than the belt
Owners describe what happened after the belt failed: loss of power in 23 reports, engine damage in 20, and lost steering or braking assist in 6. Overheating appears in 13% of complaints and a coolant or fluid leak in 17%. On many engines the serpentine belt drives the water pump, which is why a broken belt shows up as overheating. The water pump is also named in 18 of these complaints.
So a squealing or cracked belt is cheap to fix: the calculator's default estimate is $85–$173. A belt that snaps at speed can lead to a separate engine bill that no belt estimate covers.
Ram 2500 and 3500 serpentine belt chirp is covered by a Ram service bulletin for 2019–2023 trucks
Ram bulletin S2109000011 covers a squeak, chirp or tick noise from the serpentine belt area on 2019–2023 Ram 2500 and 3500 trucks and calls for additional diagnostics. Jeep bulletin 09-005-14 covers replacing the engine drive belt on the 2015 Cherokee because of belt noise.
If you own one of these trucks and a shop quotes a belt for a noise, ask for the bulletin's diagnostic procedure by number first. The noise may not come from the belt itself, and replacing the belt without that check can mean paying twice.
Serpentine belt owners went to the dealer in 111 reports, and 19% say the repair did not hold
Dealers were named in 111 complaints and independent shops in 20. Across all reports, 19% describe a dealer who could not fix the problem or a repair that had to be repeated. The pattern fits the tensioner findings: a new belt on a worn tensioner or pulley can bring the noise or slipping back.
A 2019 Toyota Tacoma owner told NHTSA: "About 70,000 miles, bearings on the idler pulley and tensioner on serpentine belt failed." At the dealer rate, the calculator's belt-only estimate is $133–$251. A repeat visit for the tensioner adds to that.
Frequently Asked Questions
My Ram 2500 chirps from the belt area. Is there a manufacturer procedure for it?
Yes. Ram bulletin S2109000011 covers a squeak, chirp or tick from the serpentine belt area on 2019–2023 Ram 2500 and 3500 trucks and calls for additional diagnostics. Give the bulletin number to the shop before you approve a new belt.
My Infiniti Q50 serpentine belt failed with low miles. Is that something other owners report?
Yes. The median mileage in Q50 owner complaints is 23,000 miles, with reports concentrated on 2017 and 2018 models. That is well below the overall median of 53,200 miles.
Why did my car overheat after the serpentine belt broke?
Overheating is described in 13% of serpentine belt complaints, and the water pump is named in 18 of them. When the belt drives the water pump, a broken belt stops the coolant from circulating. Owners linked this to engine damage in 20 reports.
