How Long Do I Have to Reject a Faulty Car? The Complete Timeline

30 days, 6 months, 6 years – the time limits for rejecting a car can be confusing. Here's a clear breakdown of your rights at each stage.

"Am I too late to reject?" It's one of the most common questions we hear. The time limits under the Consumer Rights Act 2015 can seem complicated, but they're actually quite logical once you understand them.

The Three Time Periods

Days 1-30: The "Short-Term Right to Reject"

This is your golden window.

Your Rights:

  • Reject the car for ANY fault that makes it unsatisfactory
  • Get a FULL refund – no deductions
  • Dealer CANNOT insist on repairing it first
  • You choose whether to accept repair or reject

What Counts:

  • Any defect present at delivery
  • Anything making the car not satisfactory quality
  • Anything making it not fit for purpose
  • Anything meaning it's not as described

Key Points:

Days 31-180: The "Repair or Replace" Period

Still strong rights, but the process changes.

Your Rights:

  • Request repair OR replacement (your choice initially)
  • If repair fails, you can THEN reject
  • Refund may have a small deduction for use
  • Burden of proof is still on the dealer

The Process:

  1. Report the fault to the dealer
  2. Request repair or replacement
  3. Give them ONE reasonable chance to fix it
  4. If repair fails or they refuse, you can reject

Key Points:

  • "One chance" means one proper attempt, not multiple
  • If the same fault recurs, the repair has failed
  • If new faults appear, they're treated separately
  • Dealer must prove fault wasn't present at sale

6 Months to 6 Years: Long-Term Rights

You still have rights, but you need to prove more.

Your Rights:

  • Request repair, replacement, or partial refund
  • Can reject if repair/replacement fails
  • Refund will likely have deduction for use

The Catch:

  • YOU must prove the fault existed at sale
  • Usually requires independent inspection
  • Dealer can argue it developed after purchase

What Helps:

  • Known issues with that model
  • Technical service bulletins
  • Expert inspection reports
  • Evidence of how the fault developed

When Does the Clock Start?

Delivery Date, Not Purchase Date

The 30 days begins when you take physical delivery of the car, not when you pay or sign papers.

Example:

  • You pay a deposit on 1st March
  • You sign finance documents on 5th March
  • The car is delivered on 10th March
  • Your 30-day window runs until 9th April

What If Delivery Is Delayed?

If the dealer holds the car for prep work, the clock doesn't start until you actually receive it.

Collection vs Delivery

Whether you collect or they deliver, the clock starts when you take possession.

What Pauses or Extends the Time?

Time for Diagnosis

If the car is with the dealer being diagnosed, some argue this pauses the clock. It's not settled law, but:

  • Document when you handed it over
  • Note when you got it back
  • The 30 days should reflect time YOU had the car

Attempted Repairs

If you agree to a repair attempt within 30 days:

  • You LOSE your short-term right to reject
  • You move to the "repair or replace" stage
  • This is why saying no to repairs within 30 days is often wise

Disputes and Negotiation

Ongoing discussions don't pause the clock. If you're negotiating while the 30 days tick by, you may lose your strongest position.

Calculating Your Deadline

The 30-Day Deadline

Delivery date: The day you take possession (day 1) Last day to reject: 30 days later

Example: Delivery on 15th January = deadline 14th February

Tips for Timing

  • Act immediately when you discover a fault
  • Put your rejection in writing ASAP
  • Email creates an instant timestamp
  • Don't wait to see if it gets worse

What If You're Close to a Deadline?

Near Day 30

If you're approaching day 30:

  1. Send a rejection email immediately
  2. State the fault clearly
  3. Reference the Consumer Rights Act 2015
  4. Request a full refund
  5. Follow up with a posted letter

Even if you send it on day 29, you've exercised your right in time.

Near 6 Months

If you're approaching 6 months:

  1. Report the fault in writing NOW
  2. Request repair under CRA 2015
  3. The clock effectively resets for the repair attempt
  4. Document everything

Common Timing Mistakes

Waiting Too Long to Complain

Some people:

  • Hope the problem goes away
  • Keep driving despite issues
  • Wait for it to get worse
  • Miss the 30-day window

Act fast. You can always accept a repair later – you can't recover the right to reject.

Accepting a Repair Within 30 Days

Dealers often say "let us look at it" or "we'll fix it for you". Within 30 days:

  • You don't have to accept this
  • Accepting repair loses your rejection right
  • Say no if you want to keep your options open

Not Putting It in Writing

Verbal complaints don't prove timing. Always:

  • Email your rejection
  • Keep sent messages
  • Use recorded delivery for letters
  • Screenshot everything

Assuming You're Out of Time

People often think they've missed the window when they haven't. Even after 30 days or 6 months, you still have rights – they just work differently.

Quick Reference Table

| Time Period | What You Can Do | Burden of Proof | Refund | | ---------------- | --------------------------- | --------------- | ------------------- | | 0-30 days | Reject outright | Dealer | Full | | 31-180 days | Repair/replace, then reject | Dealer | May deduct for use | | 6 months-6 years | Repair/replace, then reject | You | Will deduct for use |

Real Scenarios

Scenario 1: Fault on Day 7

You notice an engine warning light a week after delivery. Action: Reject immediately for full refund. Do NOT accept repair.

Scenario 2: Fault on Day 45

Gearbox starts making noise 6 weeks in. Action: Request repair in writing. If it fails, reject. Small deduction possible.

Scenario 3: Fault on Month 8

Suspension fails 8 months after purchase. Action: Get independent inspection proving fault existed at sale. Request repair, then reject if it fails.

The Bottom Line

Time matters, but it's not as restrictive as dealers want you to think.

  • Within 30 days: Act fast, reject outright, don't accept repairs
  • Within 6 months: Still strong position, one repair attempt then reject
  • After 6 months: Rights continue, but get evidence first

Whatever stage you're at, the key is acting promptly and putting everything in writing.
