Overview

If your 2023 GMC Yukon has repeating or unfixable problems in New Jersey, you may qualify for relief under NJ’s New Car Lemon Law. The law can force the manufacturer to repurchase or replace a defective vehicle when certain conditions are met.

The key is consistent documentation and following NJ’s specific process, including giving General Motors a final chance to repair after written notice.

Do You Qualify?

  • Covered vehicle: A new (or leased new) 2023 GMC Yukon purchased or leased in NJ for personal, family, or household use.
  • Defect covered by warranty: A problem that substantially impairs use, value, or safety and is not caused by abuse, neglect, or unauthorized modifications.
  • Repair attempts: The same defect has been repaired 3 or more times by an authorized GMC dealer and continues, or the Yukon has been out of service 20+ cumulative days for warranty repairs.
  • Timing window: The repair attempts or days out of service happened within the first 24 months or 24,000 miles from delivery (whichever comes first).
  • Final chance to repair: You sent the manufacturer a certified letter demanding a last repair opportunity and allowed a reasonable time (up to about 10 days) for that final attempt.
  • Proper documentation: You have repair orders, dates, mileage, and descriptions showing the repeated defect or total days out of service.

How NJ Law Applies

New Jersey’s New Car Lemon Law (N.J.S.A. 56:12-29 to 56:12-49) presumes a lemon if the vehicle meets the repair-attempt or days-out-of-service thresholds within the 24 months/24,000 miles window. You must also give the manufacturer direct written notice and a final opportunity to fix the issue.

If you qualify, the manufacturer must provide a refund or a comparable replacement . A refund typically includes the purchase price, taxes, and certain fees, minus a use deduction based on miles driven before the first repair attempt for the defect.

If GM has a state-certified informal dispute program (for GM, usually BBB Auto Line) you may be required to use it before filing a Lemon Law case with the NJ Division of Consumer Affairs or in court.

Step-by-Step: What to Do

  1. Step 1: Document everything. Keep all repair orders, note dates the Yukon is at the dealer, mileage at each visit, and detailed descriptions of the issue. Photos/videos help.
  2. Step 2: Use an authorized GMC dealer. Clearly describe the same problem each visit so records show a repeated defect. Ask that all diagnostics and fault codes be listed on the repair order.
  3. Step 3: Send certified notice to GM. After multiple unsuccessful repairs (or significant days out of service), send a certified letter, return receipt requested , to GM (address in your warranty booklet) invoking NJ Lemon Law and requesting a final repair opportunity . Keep copies and the green card.
  4. Step 4: Allow the final repair attempt. Provide the vehicle and a reasonable time (generally up to 10 days). Keep the final repair order.
  5. Step 5: Open a claim. If not fixed, file with GM’s BBB Auto Line if required, and/or the NJ Lemon Law Unit . Request a repurchase or replacement . Include all documents (purchase/lease, registration, repair orders, loan/lease statements, correspondence).
  6. Step 6: Calculate your ask. For repurchase, prepare a mileage offset based on miles at the first repair attempt for the defect. Include incidental costs allowed by law (e.g., towing) with receipts.
  7. Step 7: Consider other claims. If you’re outside the 24 months/24,000 miles window but still under warranty, you may have rights under the Magnuson-Moss Warranty Act or state warranty law.

Common Mistakes to Avoid

  • Not sending certified notice: Skipping the written “final repair” letter to GM can sink an otherwise strong NJ claim.
  • Thin paperwork: Verbal complaints don’t count. Ensure each repair order states the same recurring defect and includes dates and mileage.
  • Using non-authorized shops: Warranty and Lemon Law claims require repairs through authorized GMC dealers .
  • Missing the window: Waiting past 24 months/24,000 miles for qualifying attempts can defeat the NJ presumption.
  • Changing the complaint description: Keep the problem description consistent so it’s clearly the same defect across visits.
  • Aftermarket modifications: Avoid mods GM could blame for the defect (tunes, suspension changes, etc.).
