Dealer visit checklist
2025 GMC Sierra 1500 checklist
Print it or keep it on your phone. Tick each item as you go so nothing gets missed.
Inspect the car
- Check every panel gap and look for mismatched paint (signs of past accident repair)
- Look at the tires: even wear, matching brands, at least 4/32" tread
- Check under the car and engine bay for oil, coolant or other leaks
- Start the engine cold; listen for knocks, ticks or squeals and watch for smoke
- Test every window, lock, seat, light, the A/C, heat and infotainment
- Test drive on city streets and highway: straight braking, smooth shifts, no pulling
- Ask for the service records and a vehicle history report
- Have an independent mechanic do a pre-purchase inspection (about $100–$200)
Known 2025 GMC Sierra 1500 problems to check
- Oil consumption issues have been reported on the 5.3L V8 EcoTec3 engine, particularly in higher-mileage examples — monitor oil levels between changes
- Infotainment connectivity glitches with the 13.4-inch touchscreen, including occasional freezes and Apple CarPlay dropouts, have drawn owner complaints
- Active Fuel Management (AFM) cylinder deactivation on the 5.3L V8 can cause lifter failures over time — a known GM issue across multiple model years
- Tailgate latch and MultiPro tailgate mechanism complaints about rattles and intermittent failure to latch securely
- Rust and corrosion on brake rotors can develop quickly with infrequent driving, though this is common across the segment
Ask: have these recalls been fixed?
- EQUIPMENT ADAPTIVE/MOBILITY:WHEELCHAIR RESTRAINTS/SECUREMENT:LATCH/ANCHOR:: Rollx Vans (Rollx) is recalling certain GMC Yukon, Sierra, Chevrolet Express 2500, Ford Transit, E-250, Toyota Sienna, Sienna Hybrid, Honda Odyssey, Chrysler Town and Country, Voyager, Pacifica, Dodge Grand Caravan, and Ram Promaster vehicles equipped with QRT-Deluxe and QRT-Max wheelchair restraints.
Negotiate the price
- Know the typical price: about $45,000 for this model year
- Negotiate the out-the-door price, not the monthly payment
- Get the full price with every fee listed in writing before you sign
- Bring your own loan pre-approval so the dealer has a rate to beat
- Say no to add-ons you didn't ask for (paint protection, VIN etching, nitrogen tires)
- Negotiate your trade-in separately, after the car's price is agreed
- Be ready to walk away; another listing is usually a click away
