Has the dealership told you “No Problem Found” even though your vehicle keeps acting up? Learn how to protect your warranty, document the defect, and preserve your Lemon Law rights.
Few things are more frustrating than taking your vehicle to the dealership for a problem you’ve experienced repeatedly—only to receive a repair order that says:
- “No Problem Found.”
- “Could Not Duplicate Customer Concern.”
- “Operating as Designed.”
- “Vehicle Operating Normally.”
- “No Codes Present.”
You know something is wrong.
The engine stalled.
The transmission jerked.
The brakes vibrated.
The infotainment screen went black.
The check engine light came on—until you arrived at the dealership.
So why can’t the dealer find the problem?
The reality is that many modern vehicle defects are intermittent. They don’t happen every time the vehicle is driven, and they may not occur during a technician’s short test drive. That does not necessarily mean the problem doesn’t exist.
If you’re repeatedly hearing “No Problem Found,” don’t ignore it. There are important steps you can take to protect your warranty rights and, if necessary, preserve a future Lemon Law claim.
“No Problem Found” Doesn’t Mean You’re Imagining It
Modern vehicles contain dozens of computers, hundreds of sensors, and thousands of electronic components.
Some defects occur only under very specific conditions, such as:
- After the engine reaches operating temperature
- During heavy rain
- At highway speeds
- After driving for an hour
- While towing
- During cold starts
- When using adaptive cruise control
- While charging an electric vehicle
- After sitting overnight
If the dealership cannot recreate those exact conditions, the defect may not appear during the inspection.
Why Dealers Sometimes Can’t Duplicate a Problem
There are many legitimate reasons a technician may be unable to reproduce your concern.
For example:
- The issue is intermittent.
- The failure only occurs under specific driving conditions.
- The computer did not store a diagnostic code.
- The problem has temporarily resolved itself.
- The technician did not experience the same conditions you did.
- The defect is still developing and has not completely failed.
Sometimes, however, the dealership may not spend enough time investigating an intermittent issue, especially when reproducing it requires extended driving or unusual conditions.
Step 1: Don’t Leave Without a Repair Order
Even if the dealer says nothing is wrong, always request a copy of the repair order before leaving.
This document may become one of the most important pieces of evidence if the problem continues.
Review it carefully.
Make sure it accurately describes your complaint, not just the technician’s conclusion.
For example, instead of:
Customer states vehicle has issue.
You want something closer to:
Customer states transmission jerks between second and third gear after driving approximately 20 minutes at highway speeds.
Even if the technician writes “Could Not Duplicate Concern,” your complaint should still be documented in detail.
Step 2: Be Extremely Specific When Reporting the Problem
Vague complaints are harder to diagnose.
Instead of saying:
“It makes a weird noise.”
Try describing:
- When it happens
- How often it happens
- Engine temperature
- Vehicle speed
- Outside temperature
- Weather conditions
- Road conditions
- Warning lights
- Sounds
- Smells
- Vibrations
- Whether passengers noticed it too
The more information you provide, the easier it is for the technician to recreate the issue.
Step 3: Take Photos and Videos (When Safe)
Technology can be your best witness.
If it is safe and legal to do so, consider documenting:
- Warning lights
- Dashboard messages
- Screen freezes
- Strange noises
- Excessive smoke
- Rough idling
- Engine stalling
- Transmission behavior
- Water leaks
- Electrical malfunctions
Videos showing the defect as it occurs can be extremely helpful during future repair visits.
Never attempt to film while driving if it would distract you or create an unsafe situation. If possible, have a passenger record the issue or pull over safely before documenting it.
Step 4: Keep a Vehicle Problem Journal
One of the best things you can do is maintain a written log.
Include:
- Date
- Mileage
- Time
- Weather
- Speed
- Road conditions
- What happened
- How long it lasted
- Whether warning lights appeared
- Whether the dealership has previously inspected the issue
Patterns often emerge over time.
For example, you may notice the problem always occurs after driving for thirty minutes or only during wet weather.
That information may help technicians identify the cause.
Step 5: Return if the Problem Happens Again
Many consumers become discouraged after one unsuccessful repair visit.
Don’t.
If the problem returns, schedule another appointment.
Each documented visit demonstrates that:
- The problem continues.
- You promptly reported it.
- The manufacturer had another opportunity to repair it.
Repeated repair orders may become valuable evidence in a warranty or Lemon Law claim—even if several state “No Problem Found.”
Step 6: Use an Authorized Dealership
If your vehicle is still under the manufacturer’s warranty, warranty-related defects should generally be addressed by an authorized dealership.
Authorized dealers can:
- Submit warranty claims
- Access factory diagnostic procedures
- Review Technical Service Bulletins (TSBs)
- Install manufacturer software updates
- Create official warranty repair records
Those records often become critical if the defect persists.
Step 7: Ask Whether There Are Technical Service Bulletins (TSBs)
A Technical Service Bulletin is not a recall.
Instead, it is guidance issued by the manufacturer describing known issues and approved repair procedures.
Ask the service advisor whether:
- A TSB applies to your symptoms.
- There are software updates available.
- The manufacturer has released revised parts.
- Similar complaints have been reported.
Sometimes the solution already exists—it simply hasn’t been applied to your vehicle.
Step 8: Don’t Ignore Warning Lights
If a warning light appears—even if it later turns off—tell the dealership exactly:
- Which light appeared
- When it came on
- How long it stayed on
- Whether the vehicle drove differently
If possible, take a photograph before the light disappears.
Many warning lights contain valuable diagnostic information.
Step 9: Save Every Repair Record
Create a dedicated folder for your vehicle.
Include:
- Purchase documents
- Warranty booklet
- Repair orders
- Invoices
- Tow receipts
- Rental car receipts
- Photos
- Videos
- Emails
- Text messages
- Notes from phone calls
Organization can make a tremendous difference if litigation becomes necessary.
Step 10: Don’t Attempt Major DIY Repairs
When a defect is covered by the manufacturer’s warranty, resist the urge to repair it yourself or have an independent shop perform major warranty-related work.
Doing so may create disputes over:
- Whether the manufacturer had an opportunity to repair the defect.
- Whether another repair caused additional damage.
- Whether factory procedures were followed.
Routine maintenance is different, but warranty defects are generally best handled through the manufacturer’s authorized repair network.
Could “No Problem Found” Still Count as a Repair Attempt?
In many cases, yes.
Whether a particular visit counts under your state’s Lemon Law depends on the specific facts and the applicable law.
If you reported the defect, presented the vehicle for warranty service, and the dealership documented your complaint—even if it concluded that it could not duplicate the problem—that visit may still be relevant when evaluating whether the manufacturer had a reasonable opportunity to repair the vehicle.
An experienced Lemon Law attorney can review your repair history and advise how those visits may be treated under your state’s law.
Common Intermittent Problems Dealers Struggle to Reproduce
Some of the most common examples include:
- Engine stalls occasionally
- Rough idle after cold start
- Random transmission hesitation
- Electrical glitches
- Backup camera failures
- Infotainment screen freezing
- Bluetooth disconnecting
- Battery draining overnight
- Warning lights that come and go
- Adaptive cruise control errors
- Blind spot monitoring failures
- Lane keeping assist malfunctions
- EV charging interruptions
- Hybrid battery warning messages
These issues often require repeated documentation before a permanent diagnosis is made.
Should You Get a Second Opinion?
Sometimes, yes.
If the dealership repeatedly says “No Problem Found,” another authorized dealership may:
- Have more experience with your model.
- Be familiar with a common issue.
- Recognize a recently issued TSB.
- Have a technician with specialized expertise.
Remember to provide the second dealership with copies of your previous repair records.
When Should You Contact a Lemon Law Attorney?
Don’t assume you must wait until the dealership finally identifies the defect.
You should consider speaking with an attorney if:
- The same issue keeps occurring.
- The dealership repeatedly says “No Problem Found.”
- Your vehicle has been in the shop multiple times.
- The defect affects safety.
- The vehicle has spent weeks out of service.
- The manufacturer denies warranty coverage.
- You are concerned about preserving your rights before statutory deadlines expire.
Many Lemon Law attorneys offer free consultations, and in many states the manufacturer may be required to pay the consumer’s reasonable attorney’s fees if the claim is successful.
Frequently Asked Questions
If the dealer says “No Problem Found,” does that mean nothing is wrong?
No. It simply means the technician was unable to confirm or reproduce the problem during that visit. Many legitimate defects are intermittent and occur only under certain conditions.
Can a “Could Not Duplicate” repair order help a Lemon Law case?
Potentially, yes. A repair order showing that you repeatedly reported the same problem may help demonstrate that the manufacturer had multiple opportunities to diagnose and repair the defect, even if the technician could not reproduce it each time.
Should I keep bringing the vehicle back?
If the defect continues, yes. Continued warranty repair visits create additional documentation and give the manufacturer further opportunities to address the problem.
Should I record the problem?
If it can be done safely and legally, photos and videos of warning lights, noises, or other symptoms can be valuable. Never record while driving if it would distract you or create a safety risk.
Can I go to another dealership?
Yes. Another authorized dealership may have different technicians, more experience with your model, or access to updated repair information that could help diagnose the issue.
The Bottom Line
Hearing “No Problem Found” can be incredibly frustrating, but it does not necessarily mean your vehicle is functioning properly—or that you have no legal rights.
Intermittent defects are common in today’s technologically advanced vehicles, and many serious problems take multiple visits before they can be diagnosed. The key is to remain persistent, document every symptom, save every repair order, and continue presenting the vehicle to an authorized dealership when the problem recurs.
If the dealership repeatedly cannot identify or permanently repair a defect that substantially affects your vehicle’s use, value, or safety, you may have rights under your state’s Lemon Law or other warranty laws. An experienced consumer protection attorney can evaluate your repair history, explain your options, and help determine whether the manufacturer has had a reasonable opportunity to correct the problem.
