During cruise on highway (I-95 in Florida) while on vacation the left rear power sliding door became unlatched and warning chimes sounded repeatedly and interior lights illuminated, this occurred several times again on this trip there was an investigation by the NHTSA in 2008 report #EA07019 which determined no defect was present which would require a recall. I beg to differ with that assessment there most certainly is a problem here, GM issued tsb #07-08-007 and #07-08-007 A-D which tells dealerships how to repair this problem. Please look into this matter again it is very unsettling to have my kids riding in the rear and having a door unlatch at highway speeds thank you for your time and consideration.

We were pulling into walmart parking lot and hit street bump that turn onto walmart's property and the sudden jerk made the keys pop out of the ignition while the van was in motion. The keys were on the floor but the vehicle was steel in motion. As we parked the vehicle I put the key back into the ignition like nothing ever happened. I turn the van of, then waited a few minute and started the vehicle and behold the key would surely come out. I contacted the dealer Sierra Chevrolet in bartlet, tn and they checked the vehicle out and said it was a bad cut in the key. That means a bump key would start the vehicle. The ignition switch is faulty, and seeing GM recall list, the Buick Terraza 05 should be on that list. I'm writing Buick/GM with this statement and request.

2005 Buick Terraza while doors are locked and you are driving down the road. The sliding doors decide to open all on their own. You have to stop the van and shut the doors. With the door buttons are turned off they still open just not as often.

- Oak Hill, OH, USA

Buick Terraza just shuts down while driving (at various speeds) or stopped without warning. Everything shuts down with display stating, "starting disabled, reduced engine power." I must try to get to the side quickly. After about 30 seconds, the van restarts and continues for a while until it does the exact same thing again.

There are several defects that I am experiencing with this van. These issues escalated this weekend, the traction control and system stability indicators came on again and caused the brakes to lock I changed the brakes because I thought that was the cause it was not. Also the rear sliding doors will open while driving on their own. This van has been in the shop at lou fusz saint louis, mo several times and it is still not operating. This is a safety issue I am lucky that I was not on the highway when the brakes locked up, unfortunately that is not the case with the doors. I cancelled a trip to the zoo with my kids because the doors opened on their own while on the interstate, they are now afraid to ride in the back seats.

My name is [xxx] owner of 2005 Buick Terraza.we have always had a problem with the starter getting stuck/frozen, we have also talked to other owners of this vehicle, an they also have had the same problem. I feel there has to be a recall on this problem but I am sure Buick does not make this a recall because they have no fix ( B.S.) to this problem. We feel like getting a lawyer T see if maybe then theycould fix this. The dealer says our warranty no longer covers. We have had this problem since day one. With 10 miles on the new vehicle. Please help us. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Buick Terraza drivers side rear door faulty. Doot sensor keeps chiming sensing the door is open when it's not, you can't manually shut it since the sensor unlocks it and the door opens. You have to force it shut and deal with the chiming- J=hopefully I can get the sensor disconnected.

The rear door on the driver's side starting trying to open on its own the week of March 15. The soonest we could get an appointment at the mechanics was March 19. We Transport grandchildren daily to and from school and other activiites and they are always in child safety restraints. It is a good thing because March 18 as we were driving to dinner with the children, the door completely opened as we were turning a corner at a busy intersection. We have not been able to get it repaired because the parts had to be ordered. We are not driving the van with the children as we wait for repairs. The extended warranty and GM dealers do not seem to be too concerned about the safety aspect. We are!!

I was involved in an accident and had front end damage. The air bag sensor and light are on indicating that the air bag deployed; however, it did not. We have also experienced electrical problems as well with the van. The sliding door chime comes on randomly when I we are driving. Work had to be done previously on the wiring. Occasionally I hear rattling noises from the front end of the vehicle when I drive. The van also shakes excessively when approaching speeds over 45-50 miles per hour when I put on the brakes.

Both sets of keyless entry failed on the unlock operation. One set was used and failed in 2 years, the other set was then used and failed in two years. Must have something wrong in the makeup of these keyless transmitter. Everything works except the unlock. Replacement quoted at $345.

Since October 2006 I have taken the '05 Buick Terraza to mossy Pontiac Buick GMC of new orleans for the following issues: Dvd static noise, unusually loud, exhaust noise on take-off, brakes, ABS lights come on, onstar, and ignition/starter continues to turnover after releasing the starter key. After 10-15 visits to the dealership for the same issues they say that they replaced the muffler and the catalytic converter, and that any noise I hear is inherent to the vehicle. I was also informed that the dvd noise I heard was inherent to the vehicle up until my last visit on April 10, 2007 at which time I was informed of a bulletin that described the problem I had been having since October 2006. Either way, that issue was still not fixed after leaving my vehicle at the dealership for approximately 10 hours. Also, according to the dealership the ABS light issue and the ignition/starter issue could not be duplicated. Therefore, they are likely inherent to the vehicle. I placed a complaint with Buick customer care on April 10 after not having any resolution to my problems, and they informed me that there is nothing they can do other than offer me a $1000 rebate for buyer loyalty towards a new GM vehicle. My car current has 38,600 miles, but I purchased it with 23K (certified which supposely exended the warranty to 39K) and have been taking it to the dealship for issues since the day of purchase. Any help that you all can give me to help resolve this matter would be greatly appreciated.
