Ask for the complete service file before you price a second-generation Acura NSX. The car pairs a twin-turbo V6 with three electric motors and a nine-speed dual-clutch transmission. Low mileage does not show whether its scheduled work, warnings, or recall work are current. Match every record to the VIN, date, and mileage. Then let an NSX specialist inspect what the file cannot prove.

What does the hybrid system change?
The second-generation NSX has more than an engine service history. Acura's 2017 power-unit description identifies three electric motors, a twin-turbo V6, and a nine-speed dual-clutch transmission. Two motors operate at the front wheels. Those are separate systems with records worth finding.
Start with identity. Ask the seller for the VIN, the model year, and every service invoice before you travel or send a deposit. Then ask an Acura or NSX specialist which records should exist for that exact year and use pattern.
An invoice that says only "service completed" is thin evidence. It does not say what the shop checked, what it found, or which fluids and parts it used.
Build the file in date order
Put the invoices in date order. Each entry needs a date and mileage.
Ask the seller for these five groups:
- Maintenance Minder records and the codes shown when the work was due.
- Engine, transmission, brake, tire, and coolant service invoices.
- Diagnostic reports for warning lights, stored faults, or hybrid-system messages.
- Repair orders for the high-voltage system, electric motors, hybrid battery and power electronics, or control units.
- Recall and warranty work, with the VIN and completion date.
Acura's 2020 Maintenance Minder material lists the system's maintenance messages and codes. Use the correct model-year document. A code can prompt a useful seller question, but it cannot prove the work was completed without an invoice.
Keep the original documents where possible. A spreadsheet made for the sale can help you read the sequence. It cannot replace workshop records.
Match each code to completed work
A Maintenance Minder code tells you what Acura called for at that point. It does not show that a shop completed the job. Put the code beside the dated invoice, the mileage, and the actual work description. If the invoice says only “annual service,” ask for its itemized work order. The correct answer can be a missing scan, a missing document, or a job still due. Keep those outcomes separate.
The 2020 Acura Maintenance Minder document gives code meanings for that model year. It does not give a universal service history for every NSX. Ask the specialist to use the schedule for the car's own model year and market. A code from a 2020 reference cannot settle a question about another year without that check.
Read large jobs in both directions. What warning or condition led to the repair? What did the shop replace or update? What later record shows the car returned without the same warning? A paid invoice can document the middle step while leaving the cause and result unclear. Ask for the diagnostic report and the follow-up order when either end is missing.
Ask what happened after every warning
A cleared warning is not a repair record. Ask what message appeared, when it appeared, which shop read the car, and what the final repair order says.
Acura's owner material identifies high-voltage components and gives safety guidance for the NSX. That is a reason to keep hybrid-system work with a qualified specialist. It is not a reason to diagnose a high-voltage fault from a listing or a photo. Acura's 2019 safety document applies to its named model year. Confirm the procedure for the car in front of you.
Ask the inspector to report three things separately:
- what the records verify;
- what the diagnostic read shows now; and
- what remains unknown.
That last list matters. Missing scans, missing invoices, or a warning with no explanation all belong in the price discussion. A clean dash on one viewing is not the same evidence.
A warning in a hypothetical service file
Consider a hypothetical 2019 NSX listing. Its seller supplies routine invoices and a later order that says a hybrid warning was cleared. The order does not state why the warning appeared. You cannot treat “cleared” as a completed repair. Ask for the stored fault report, the technician's diagnosis, and any later test that checked the affected system.
Suppose the seller then sends a second order that names a component and a completed repair. Match its VIN and date to the first order. Send both to an NSX specialist. Ask the specialist whether the present diagnostic read shows a related fault and which checks are still possible. A clean current read is helpful, but it cannot recreate every event that happened before the repair.
If the seller cannot obtain the diagnosis, keep the warning at Check. Ask the specialist whether it can define the present condition and estimate any work it finds. If the shop cannot test the relevant high-voltage system safely, record that limit. Do not treat the missing diagnosis as proof of a failed hybrid battery or invent a repair price. The decision is whether this file supports the risk you would take.
Check recalls by VIN
Run the VIN through the NHTSA recall lookup and save the result with the service file. NHTSA says its tool shows unrepaired safety recalls. It does not show all maintenance, accident, warranty, or repair history.
If the lookup shows an open recall, ask an authorized Acura dealer whether the VIN is eligible and what work remains. If the result shows none, keep going. A recall result is one safety check. It is not a service history.
NHTSA's VIN lookup may omit recalls more than 15 years old unless a manufacturer offers more coverage. It also omits international vehicles and some small manufacturers. Ask an Acura dealer to check the VIN record and completed campaigns. Follow any interim safety instructions, including a do-not-drive warning, before transport or a test drive. Save the dealer's answer with the invoice sequence.
What should a specialist inspect?
The service file can show that a shop recorded work. It cannot confirm present condition. A pre-purchase inspection, or PPI, is a paid check by a shop the seller does not choose.
For this NSX, ask whether the specialist can inspect the hybrid system, run an appropriate diagnostic read, and explain any active or stored faults. Ask for a written report on the powertrain, transmission, cooling, brakes, tires, body, underside, and road test when conditions allow.
The specialist should also identify gaps in the file. That is where a low-mileage car can get expensive. Mileage measures distance. It does not document storage, warning history, missed maintenance, or the cause of a prior repair.
Give the shop a single brief with the VIN, model year, current mileage, Maintenance Minder records, and every warning or repair order. Ask for the systems it can check, the test method, and any condition that prevents a safe road test. The written result should distinguish a current fault from an old record gap. Those lead to different questions for the seller.
Do not ask the shop to promise that the hybrid system will have no future fault. Ask it to report present findings and the work it recommends now. If it identifies work, get a written quote before setting a walk price. A low asking price is only useful after the unknown work has a documented basis.
Our NSX Gen 2 pre-purchase inspection checklist covers the wider inspection request. Use it with this record checklist, not instead of it.
Deal, Check, or Walk
| Verdict | When it fits |
|---|---|
| Deal | The VIN, dates, mileage, and invoices form a consistent service sequence. The specialist can read the car and finds no material unanswered issue. |
| Check | A warning, recall answer, record gap, or diagnostic result needs explanation or a written repair estimate. |
| Walk | The seller will not provide the VIN, the full service file, or an independent NSX specialist inspection path. |
Resolve missing service records before relying on a low asking price.
If the records hold up, compare the asking price with the right evidence in Value Check. Then review the NSX market page and how exotic-car price charts work before you treat any advertised number as a complete answer.
Do not rely on Exotic Index alone. Always review title, service history, accident history, ownership records, seller documentation, and obtain an independent pre-purchase inspection before buying.
