Used Buick Terraza Buying Guide: 2005-2007 Engines, AWD and Recalls

A used Buick Terraza (2005-2007) is the plush version of GM's last minivan family, and the smart buy is usually a 2007 with the 240-hp 3.9-liter V6, or a 2005-2006 with all-wheel drive if you really need it. Before you pay, confirm the 2005 parking brake recall was done, check under the driver's seat for a wet, corroded connector, and accept that IIHS rated its head restraints Poor. The Buick premium buys quiet, a standard rear-seat DVD and an independent rear suspension; underneath, it's the same GM van as its siblings.

Buick only sold the Terraza for three model years, so listings are thin and you may have to drive a while to see a decent one. On Monday, October 19, 2026, I read Consumer Guide's 2005-07 Terraza review, Car and Driver's Terraza CXL road test, the IIHS file and NHTSA's recall list for each year. Honestly, neither review loved it.

What makes it a Buick and not an Uplander

The Terraza shares its basic design with the Chevy Uplander, Pontiac Montana SV6 and Saturn Relay, all of which grafted an SUV-style nose onto the 1997-2004 GM van. Consumer Guide calls the Terraza the costliest, most luxurious of the group and the only one with standard load-leveling suspension. Car and Driver adds a detail that matters on the road: the Buick got an independent rear suspension adapted from the Rendezvous, while its siblings got that setup only with all-wheel drive. Our used Saturn Relay guide covers the plainer twin if you'd rather not pay for leather.

Trims were CX and CXL, with a CX Plus added for 2007. Every Terraza seats seven, and standard equipment included a DVD entertainment system, OnStar, four-wheel ABS and 17-inch wheels. CXL added leather, a power driver-side sliding door and rear obstacle detection. One thing you won't find on any of them is a curtain side airbag, because GM never offered one on this van. Front side airbags were optional on CX and standard on CXL.

Engines and drive by year

• 2005-2006: 3.5-liter V6, about 200 hp in front-drive form and 196 hp with AWD, four-speed automatic. Front-drive vans had StabiliTrak.
• 2006: second-row side airbags became available.
• 2007: AWD dropped; every Terraza got a 240-hp 3.9-liter V6.

Car and Driver's 2005 CXL weighed 4,514 pounds and needed 10.6 seconds to reach 60 mph, slower than the older GM vans it replaced. Its testers griped about seats that fold flat only on top of the floor instead of into it, hard plastic seatback bins that hit tall passengers' knees, and a $31,885 starting price for the CXL. Consumer Guide's verdict was blunter: a Caravan or an Odyssey "makes more sense." On the plus side, both said it was quiet. Use our Buick VIN decoder guide to confirm the engine and drive on the van in front of you, since a seller calling a 2005 "the 3.9" is a red flag.

What a history report won't tell you

None of Consumer Guide's trouble spots would ever show up on a CARFAX or AutoCheck report, and a few can strand you. On 2005-2006 vans, the wiring connector under the driver seat can get wet and corrode, so the engine may not start, may start and quit, or light up assorted warning lamps. Sulfur corrosion of the fuel level sender can make the gauge read fuel that isn't there. Expect possible EGR valve failures with a check-engine light, a PCV tube that whistles on the 2005 3.5, flickering lights traced to the alternator and an OnStar module that dies.

So do the boring checks. Feel the carpet under the driver seat, watch the fuel gauge after you fill up on a test drive, and scan for stored codes. Then look at the load-leveling rear: the van should sit level when empty.

Recalls, including a strange one

For a GM van this era, the Terraza's NHTSA list is short. The 2005 recall 05V287 says some vans failed the federal parking brake hold test on a steep hill, and dealers were to inspect for lever slippage at each rear caliper and replace calipers where needed. The 2006 recall 05V552 was a misprinted tire and loading label. NHTSA also lists a Dorman aftermarket steering knuckle campaign and 10V110, a Braun Corporation recall of GM wheelchair-accessible conversions for 2005-2008 where a modified trailing arm may not have been welded properly. If the van has a lowered floor and a ramp, that one is yours to chase, and the conversion company is the place to ask. Our Buick recall check by VIN walkthrough explains how to get a straight answer on any van.

Crash ratings

IIHS tested a 2005 Uplander and applies the result to 2005-07 Terrazas: Good in the original moderate overlap frontal test, though the dummy's head bottomed out the airbag and hit the steering wheel. Head restraints and seats were rated Poor. Car and Driver says the longer nose lifted NHTSA's frontal rating from four stars to five, and Consumer Guide shows five stars for both front seats on a 2006. Side protection is the weak spot, given no curtain airbags.

Before you hand over money

Check the VIN on NMVTIS for brands, then get a current report yourself instead of reading the dealer's copy. We're a licensed CARFAX and AutoCheck reseller with no affiliation to CARFAX, AutoCheck, Experian or GM; as of mid October 2026 a guest report was about $5.50, a member report about $4.50 and the pair about $6.75, compared with roughly $39.99 to $44.99 retail. Confirm the total when you check out.
