When the Repair Manual Is the Law

Short answer: A carmaker's repair manual binds nobody by its own force, but other instruments reach out and adopt it. In California a state regulation sets the accepted trade standard for auto body and frame repairs: procedures shall be performed in accordance with OEM service specifications or with service specifications that are nationally distributed, periodically updated and generally accepted by the industry, with no contract and no certification involved. In Texas one jury has already measured a shop's care against the manual after two people were burned, in a verdict that binds no other court. We did not read the negligence or evidence law of any other state. Whether your insurer has to pay for what the manual says is a separate question, answered by insurance regulation.

The manual is a book until an instrument picks it up

Honda publishes a body repair manual. So does every other manufacturer. Publishing it does not make it law, and a position statement announcing that the manufacturer "requires" pre-repair scanning has, standing alone, the legal weight of a manufacturer's opinion about its own product.

What changes that is adoption. A state regulator can write the manual into a licensing standard. A jury can take it as the measure of ordinary care. An insurance statute can make ignoring it an unfair claims practice. A private certification agreement can turn it into a contract term. Those four instruments bind different parties, are enforced by different people, start biting at different moments, and leave different alternatives open.

So the useful question in a repair shop has more than one part. Required of whom? Enforced by whom? Starting when? And with what alternative, if any?

California adopted it as a licensing standard

California Code of Regulations, title 16, section 3365 is headed "Auto Body and Frame Repairs". It defines the accepted trade standard for auto body and frame repair work rather than naming the people it binds. The link to licensed shops is in the citations printed under it: the section is issued under sections 9882 and 9884.19 of the Business and Professions Code and referenced to sections 9884.7, 9889.50 and 9889.52, which is the route by which falling below the standard becomes a disciplinary matter for a licensed automotive repair dealer. It asks nothing about whether the shop has any relationship with the manufacturer. It reads: [STATUTE]

"The accepted trade standards for good and workmanlike auto body and frame repairs shall include, but not be limited to, the following: (a) Repair procedures including but not limited to the sectioning of component parts, shall be performed in accordance with OEM service specifications or nationally distributed and periodically updated service specifications that are generally accepted by the autobody repair industry. (b) All corrosion protection shall be applied in accordance with manufacturers' specifications or nationally distributed and periodically updated service specifications that are generally accepted by the autobody repair industry."

Read the word "or". It carries most of the weight in this regulation and it is the first thing to disappear when the rule gets summarised. Section 3365 is a floor with two doors. One door is the OEM service specification.

The other door is narrower than it looks. It takes a specification that is nationally distributed, periodically updated and generally accepted by the autobody repair industry, and the regulation joins those three conditions rather than offering a choice among them. A specification has to satisfy all three to get through.

A California shop that used a procedure that is nationally distributed, periodically updated and generally accepted by the autobody repair industry, all three of those and not merely written down somewhere, has an argument under this rule; a shop that improvised has none.

That matters directly to your situation. If your shop says the manual requires something, section 3365 obliges it to work to a specification of one of those two kinds. The manufacturer's satisfies the first door outright. Anything else has to clear all three conditions of the second.

We do not claim that section 3365 has ever been enforced against a shop over a procedure deviation. We opened the rule on two independent hosts. We opened no citation and no disciplinary decision under it, and we do not know how often the Bureau of Automotive Repair uses it, if ever.

We also opened one state's rule. If you are not in California, nothing here tells you whether your state has an equivalent. Ask your state's repair licensing board.

A jury adopted it once, expensively, after two people were burned

Seebachan v. John Eagle Collision Center, cause DC-15-09782, 192nd District Court, Dallas County, Texas.

A 2010 Honda Fit had hail damage and the shop replaced its roof. Honda's body repair manual called for the roof to be tack-welded at the corners and then attached with a combination of spot welds and MIG plug welds; the shop panel-bonded it on with adhesive instead. [REPORTED] Years later the car was struck head-on, the roof structure failed, and the car caught fire with two people inside.

The theory pleaded was ordinary negligence: the duty a repairer owes because it undertook the repair. On 2 October 2017 the jury returned roughly $41.97 million and apportioned 75 percent of the responsibility to the shop, about $31.5 million. [ADJUDICATED, trial level]

A jury verdict is not precedent. It is one jury's answer about one roof, and it binds no other court. We found no appellate opinion in this matter, and searches that reliably returned the case returned no appellate decision, which is evidence of absence rather than proof of it.

There is also something the repetition of "$31.5 million" across seven years of trade coverage leaves out. The Texas firm Colvin, Saenz, Rodriguez & Kennamer lists this cause in its own trial activity page, records that one of its partners defended John Eagle Collision CTR, records the verdict and the apportionment, and then records this: [REPORTED]

"Before the jury verdict, the Parties agreed to a confidential high low settlement agreement."

A high-low agreement fixes a floor and a ceiling on what will actually be paid, whatever number the jury returns, and it is struck before the verdict comes back. If one was in place here, then $31.5 million is the jury's figure and not necessarily anyone's cheque. We are not saying the Seebachans went uncompensated or that the shop escaped consequences. We do not know the terms of a confidential agreement, and the firm that published that sentence was John Eagle's own counsel in this case, which is a stronger reason to hold it at arm's length rather than to throw it away. No other source we opened mentions it.

What survives all of that is the part that should interest a shop owner. On the theory pleaded in this Texas case, the exposure for departing from the manual ran to the people in the car, and it did not depend on the shop having signed anything with the manufacturer. Honda was not a party to the case and recovered nothing.

Whether a court in your state would let a jury use a manufacturer's manual the same way is a question we did not read.

Your insurer is a different instrument

Now the thing you actually asked about.

Nothing in a repair manual obliges an insurance company to pay for what it says, and the instruments that can make your shop follow the manual are not the instruments that can make your insurer fund it.

Rhode Island is one state that has pointed an instrument at the payer. Its Unfair Claims Settlement Practices Act, R.I. Gen. Laws section 27-9.1-4, lists at subsection (a)(23) an unfair claims practice by an insurer: [STATUTE]

"Refusing to acknowledge and compensate an auto body repairer for documented procedures identified as required or recommend"

That is where the Rhode Island General Assembly's own server stopped, at 125 characters, mid-word. On Justia's copy the sentence continues, naming the original equipment manufacturer and the manufacturer's program alongside industry programs it lists as Alldata, Repairlogic, CCC Repair Methods, I-Car and paint manufacturers. We confirmed the subsection number and the opening words on both hosts and the remainder on one, so we quote only as far as two hosts agree.

Two features of that provision matter more than its existence. The insurer bears the duty. And the enforcement route runs through the insurance regulator, which puts the provision in the hands of a repairer complaining about a claims practice; a car owner complaining about a repair sits outside it.

New York Assembly Bill A245 would go further and require written authorization from the vehicle owner before a shop deviates from collision repair guidelines. It has been reintroduced across sessions and sat in committee at our last check. [carried from our earlier research and not re-opened for this article] A bill repeatedly introduced to create a duty is some evidence that the duty is not already there in that state, which is reasoning rather than a reading, and it is marked as reasoning.

Beyond those, this page makes no claim about how any particular insurer will treat any particular line on your estimate.

The certification plaque on the wall

If your shop is manufacturer-certified, its agreement with the manufacturer will typically pull the manufacturer's position statements and procedures inside the contract as terms the manufacturer itself enforces, at its discretion, against the shop. Our earlier research opened American Honda's program terms and found that structure, including termination in the manufacturer's sole discretion and a cap on the manufacturer's own liability to the shop. We could not re-open that document within this page's budget, so nothing from it is quoted verbatim here. [COMPANY]

The point for a car owner is narrow and worth stating anyway. That agreement runs between the shop and the manufacturer. It gives you no remedy against the manufacturer, and of the four instruments on this page it is the one that most clearly does not run to you.

What you can actually do

Ask the shop to put the specific procedure in writing with its source, meaning the manual section or the bulletin number. Ask the insurer in writing to state which line it is declining and why. Those two pieces of paper are worth having whether or not anything comes of them, because the gap between them is the entire dispute and neither side usually writes it down.

In California you can complain to the Bureau of Automotive Repair about workmanship measured against the section 3365 standard, though we opened no record of how such complaints are handled, so treat that as a channel and expect nothing from this page about what it produces. If you are elsewhere, ask your state's repair licensing board whether it has an equivalent standard.

And if the shop is willing to do the repair correctly while the insurer will not fund it, understand where that leaves the shop: the exposure for a wrong method sits with the repairer, which is why some shops will decline work that an insurer will only partly cover.
