The 2003 Pontiac Grand Am’s horn sits on the passenger side, tucked right behind the fog lamp, bolted into the front bumper.
How much is a Pontiac Grand Am 2003 worth?
A 2003 Pontiac Grand Am typically sells for $370–$2,380, according to mid-2026 data from Kelley Blue Book.
Price swings wildly based on mileage, body condition, and trim. Beaters with 150,000+ miles or dings on every panel? Expect the bottom of that range. Spotless low-mileage examples with service receipts? They can flirt with the top end. Always double-check the VIN on Kelley Blue Book or Edmunds before you hand over cash or keys.
Why did they stop making Pontiac Grand Am?
GM killed Pontiac entirely in 2010 during bankruptcy restructuring because the brand had become a money pit.
The Grand Am itself bowed out in 2005, replaced by the Pontiac G6. GM shut the whole division down to concentrate on its healthier brands while it clawed its way back to profitability. The final nail came in April 2010. According to GM archives, the move saved billions but left dealers and lifelong fans in the lurch.
How long will a Pontiac Grand Am last?
A pampered 2003 Grand Am can easily clear 200,000 miles if you treat it right.
Skip oil changes, let the cooling system go south, or ignore the 3.4L V6 timing chain, and you’ll be looking at catastrophic engine damage by 150,000 miles. Stick to top-tier fluids, swap the timing chain every 100,000 miles, and fix squeaks or leaks the moment they appear. Rotate those tires every 5,000 miles and keep the pressure correct—your wallet will thank you later.
Where is the PCM on a 2003 Pontiac Grand Am?
The Powertrain Control Module lives behind the glove-box door, and you can reach it by yanking the door right off.
Pop the latch, pull the glove box free from its hinge pins, and you’ll see a rectangular module bolted to the right side. Unplug the 36-pin connector by pressing the tab and pulling gently. Before you touch a thing, disconnect the negative battery terminal—PCMs hate static shocks. The factory part number is 12579089.
Is Pontiac a good car?
Pontiacs like the Grand Am and G6 were surprisingly solid daily drivers, especially the SE and GT trims from 2003–2005.
Owners loved the quick steering and comfy ride. On the flip side, electrical gremlins and suspension bushings start throwing tantrums after 100,000 miles. Northern cars often rust out in the wheel wells and subframes if they’ve seen salted roads. Give any used Pontiac a thorough undercarriage once-over and wiggle every wiring harness before you buy.
How reliable is a Pontiac Grand Am?
The 2003 Grand Am earns a 3.8-out-of-5 reliability score, pulled from owner surveys and expert reviews on RepairPal.
Watch for power-window motors that quit, front control-arm bushings that crumble, and cooling-system leaks that surprise you. The 3.4L V6 is tougher than the 2.2L Ecotec, but it still needs chain checks. Change the transmission fluid every 60,000 miles to dodge solenoid and valve-body grief—use Dexron III only. Scan TSB Central for the latest factory fixes.
Will Pontiac ever come back?
Pontiac isn’t coming back as its own brand, at least not through 2030 according to GM’s published product roadmap.
GM has dusted off the Pontiac name for one-off concepts and trim levels—see the 2025 GMC Hummer EV “Pontiac” trim—but a full revival isn’t in the cards. The brand’s 2009 bankruptcy scars still linger. Any future use will probably be limited to heritage editions or marketing stunts. Keep an eye on GM Media for official news.
Is a 2004 Pontiac Grand Am a good car?
A well-kept 2004 Grand Am is a solid used-car pick if it’s under 150,000 miles and has clean service records.
It’s comfortable, handles nicely, and sips fuel reasonably well. Spring for the optional 3.4L V6 if you want passing power without drama. Steer clear of anything with a check-engine light, transmission slips, or rust scaling the frame. Drive it around the block: listen for clunks, test every power feature, and confirm the VIN on Consumer Reports—they rank it “Above Average” in this class.
What is a 2002 Pontiac Grand Am worth?
A 2002 Pontiac Grand Am usually lists for $270–$2,090, based on 2026 Kelley Blue Book valuations.
Rust-free, accident-free cars with under 100,000 miles and glossy paint can hit the top of the range. Southern cars without frame rot command a premium. Always run a VIN check on Carfax and shine a flashlight on the frame rails. If the seller can’t produce service records or the undercarriage looks neglected, knock another grand off the asking price.
What size gas tank does a 2003 Pontiac Grand Am have?
The 2003 Pontiac Grand Am packs a 14.1-gallon tank, giving you roughly 310 city miles or 423 highway miles per fill-up.
