You dropped the car off on Monday. The shop said five to seven days. Now it is day nine and they are talking about parts that have not arrived yet. This is frustrating, and you have every right to want clear answers. Here is what actually causes delays, how a good shop should be handling it, and what you can do if the situation drags longer than it should.
The most common reasons a repair runs long
Most delays in body repair fall into a few categories. Knowing which one you are dealing with makes it easier to know what to expect next.
Parts delays. Supply chain issues affect body shops the same way they affect everything else. Some parts are backordered for days or weeks. If your car needs a specific trim piece, a specialty sensor, or a panel from a less common model, the wait can push the whole timeline. We cover how parts decisions affect a repair in our article on OEM vs aftermarket parts in collision repair.
Hidden damage discovered during the repair. When a shop opens up a car, they often find damage that was not visible from the outside. A bent bracket behind a bumper. Damage to a suspension component hidden under a fender. This is called a supplement, and it requires going back to your insurance company for additional approval. That process adds time. We explain how supplements work in our guide on collision repair supplement claims.
Insurance approval delays. Even after a supplement is submitted, the insurer may take time to review and approve the additional work. The shop generally cannot proceed on that section until approval comes through. This is not the shop holding the repair. It is the insurance company's review process adding a step in the middle.
Scheduling and workflow. Body shops run multiple vehicles through a paint booth, a frame rack, and finishing stations in a coordinated sequence. If one car in the sequence takes longer than expected, it can push others. A shop running at full capacity has less room to absorb unexpected delays without affecting other cars in the lineup.
What a good shop should be doing while you wait
A good shop keeps you updated without you having to chase them. If there is a parts delay, they should tell you before the original pickup date, not after it passes. If a supplement is going to the insurer, you should know why, what the timeline looks like, and who is following up.
You should not have to call to find out your car is two days behind. If you are the one making the calls and the updates are vague, that is worth naming directly. Ask three questions: what specifically is holding this up, what is the expected date now, and what has to happen before the car is ready. A shop that handles repairs well can answer all three clearly.
What happens to your rental car coverage
This is where a delay gets expensive if you are not paying attention. Most insurance policies cover a rental car during the repair, but the daily limit and the total covered period are capped. If your policy covers rental for a certain number of days and the repair runs past that, you pay out of pocket for the extra time.
If the delay is caused by the insurer's own slow processing of a supplement, there is sometimes a case to be made that the rental coverage period should be extended. This is worth discussing with your claims adjuster directly. The shop can document the timeline, but you usually need to make that call yourself.
Your rights as a customer
You are allowed to ask for a status update at any time. You are allowed to ask for documentation of why the repair is taking longer. You are allowed to ask what the new expected completion date is. None of these are unreasonable requests.
If the repair has gone significantly past the estimated date and you are not getting clear answers, ask to speak with a manager or owner. A family owned shop like ours takes that conversation seriously because our reputation is personal, not corporate.
In a situation where a repair has genuinely gone wrong rather than just delayed, you have additional options including a formal complaint to the Bureau of Automotive Repair, which licenses body shops in California.
How delays affect the work itself
A delay is frustrating, but a shop taking a few extra days to do the job right is almost always preferable to one that rushes to meet an artificial deadline. Paint jobs rushed before primer is fully cured, or panels installed before the right supplemental part arrives, create problems later that cost more to fix. A few extra days for a part to arrive is better than a repair that needs to be redone.
That said, a delay should always come with communication. The wait is manageable. The silence is not.
What to do right now
If your car is past the original estimate, start with a direct call to the shop. Ask the three questions: what is holding it up, what is the new date, and what needs to happen next. Write down what they tell you so you have a record of the conversation.
If the delay involves your rental coverage running short, call your insurance adjuster the same day and document that conversation too. Ask whether the rental period can be extended given the actual repair timeline.
If communication has broken down completely, the Bureau of Automotive Repair handles California body shop complaints and can offer guidance. Their website is bar.ca.gov.
What our process is designed to prevent
Every repair at Mashore Autobody runs through The Painless Collision Process. We tell you what we see up front, keep you updated at each step, and if something changes the timeline, we call you before the original date, not after. That is what The Painless Collision Process means in practice. The work falls on us, not on you.
If your car is somewhere else right now and the communication has stopped, we are happy to give you a second opinion on what is happening. Call us at 925-516-1930.
Frequently asked questions
What should I do if my car is taking longer than the body shop estimated?
Call the shop and ask three specific questions: what is causing the delay, what is the new expected completion date, and what needs to happen before the car is ready. Write down the answers. If you are not getting clear responses, ask to speak with the owner.
Can a supplement delay hold up my entire repair?
Yes. When a shop discovers damage that was not in the original estimate, they submit a supplement to your insurer for approval. The shop generally cannot complete that portion of the repair until the additional cost is approved. That review process can take several days.
What happens to my rental car coverage if the repair runs longer than expected?
Most insurance policies cap rental coverage at a daily limit and a total number of covered days. If the repair runs past that period, you typically pay out of pocket for the extra time. If the insurer's own delays caused the overrun, ask your claims adjuster whether the coverage can be extended.
Is a repair delay always the body shop's fault?
Not always. Parts backordered through suppliers, insurance supplement approvals, and hidden damage discovered during the repair can all extend a timeline in ways that are not the shop's doing. What is the shop's responsibility is keeping you informed about each of those things as they happen.
Who do I contact if a California body shop is not handling my repair properly?
The Bureau of Automotive Repair licenses and regulates body shops in California. You can file a complaint or get guidance at bar.ca.gov. For delays specifically, start with a direct conversation with the shop owner before escalating.
