2005 Buick Terraza CXL 3.5L V6 SFI


Costly to own


Rebuilt the transmission to find out it did the same thing within 100 miles. Found out that there had been a GM transmission already replaced on it. So we are on # 3 now.

Driver's heated seat gets so hot on the left side that you cannot keep it on.

The sliding door gets confused a lot, or will not open or close.

When using the radio controls on the steering wheel, it does not work properly.

Electrical issues.

Mileage is not good at all. 16 miles per gallon.

We do maintenance every 3,000 miles and winter checks etc.

Have had to replace the tires due to wear.

Back side window only opens sometimes, and then you cannot get it closed.

General Comments:

Sad that all this had to happen, as I really do like the vehicle.

Would you buy another car from this manufacturer? Don't Know

It has had two transmissions, and both have shifted erratically due to the vehicle's internal computer malfunction.

Engine main oil seal has failed.

Sliding doors do not operate properly.

Lights flicker due to poor electrical design.

Tires wear out prematurely due to inadequate suspension.

Several handles and knobs have broken under normal use.

Electric heated seats have not operated since 90,000 miles.

Traction control, ABS, and wheel hubs have been an ongoing problem.

Fuel pressurization problems with the fuel tank. This was extremely expensive.

Terraza means why my next van will be from Japan


Multiple electrical problems.




General Comments:

Bought this van new. Quite possibly the worst vehicle we have ever owned. I have kept many vehicles well over 200k miles without half the troubles this has given.

Had to have parts of the wiring harness replaced.

From new has used 2-3 quarts of oil between every oil change.

I am meticulous about maintenance; change the trans fluid and filter regularly with synthetic, and have never had to have an auto tranny rebuilt on any other vehicle except this one at around 70k. Found chunks of metal in the pan.

Warps its front brake rotors on a regular basis.

Have had to replace just about every single component of both the front and rear suspension.

Replaced the alternator, which at least fixed the flickering lights from new.

Probably other stuff I have forgotten.

2005 Buick Terraza CXL 6 cylinder


Love our Terraza!


Engine oil leak at 75000 miles.

Sliding side doors get their "brains scrambled" once in a while, and don't want to operate properly. If you are patient, it always works out OK.

Second set of brakes replaced at 114000 miles (not too bad!).

Driver seat heater element went out at 75000 miles.

Second set of tires replaced at 112000 miles (not bad!).

General Comments:

This is one fine automobile.

I wish GM were building a minivan we could buy today. I just don't know what we will replace it with. Would love to find one just like it with about 50K on it.

The Terraza is very quiet and comfortable on the road trip. It is very comfortable to enter and exit.

The handling is very stable on the road.

The van is roomy, and it is well designed. Our grandkids LOVE the built-in DVD. Don't use the OnStar or the XM radio.

The ultrasonic backup alarm is a must in our next car.

Replace it with a Buick Enclave!

I just bought a brand new Enclave, and love it. The price difference is a bit steep. I do think the Enclave is a lot more appealing than any mini-van though.

This has been the worst car purchase I have ever made


The front torsion bar broke at 21,000 miles.

The front rotors were warped and needed turning at 21,000 miles, but the pads were fine.

Back tires got bubbles in the sidewalls at 23,000 miles and needed replacing. (Goodyear)

All tires needed replaces at 38,000 miles. (Goodyear)

Front rotors needed turned again at 43,000 miles.

Drive shaft needed replaced at 43,000 miles.

Intermittent problem with side electric lock since 10,000 miles. It locks and cannot unlock with the remote or driver's button.

General Comments:

This car drives like truck, very loud and bumpy.

I bet it was in an accident before you bought it.

It appears that the odometer may have been "adjusted".
