Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

  • 60,000 miles


2011 Buick Lacrosse (60,000 miles - properly maintained by 73 year old man) broke down on interstate hwy. While vacationing in knoxville, tn - Buick begins to stall and the engine light came on (was flickering and no acceleration). We stopped immediately at a gas station and called aaa - who towed us to a certified aaa repair/tow company. We initially suspected it would be the fuel pump or filter. Mechanic in knoxville who is a ase certified mechanic for 40 years said it wasn't the fuel pump so he put his diagnostic tester and determined there were more problems and started to take apart the engine....and found the main valves were broken and fell into the pistons. Engine failure and he said in his 40 years this had happened only 3 times but not on a 2011 car with only 60,000 miles. He said if we would have continued driving, the whole engine would have blown up. Called the local Buick dealership and found out no recall, nor did we have the extended warranty (a big mistake - and we loved the Lacrosse thinking it would last a long time). Looked up blue book value - worth $11,000 (with running engine) and a new engine would be approx. $8,000 and would take a week to replace. Sold the car to the mechanic in knoxville, tn) and purchased a new Toyota avalon in knoxville. Very very disappointed in G.M.

LaCrosse 6-cyl

  • 8,000 miles
When turning left at a traffic light, my car lost power and I wasn't sure I was going to make it around the corner. After a few seconds my car regained power. 45 minutes later, I made a right turn into heavy traffic and then felt a sudden lurch. I looked in the rear view mirror and saw that my trunk had popped open. I managed to get off the highway, parked the car and turned off the ignition. I got out, closed the trunk, got back in the car, and fastened my seatbelt. Before I could close the door, the trunk popped open again. This occurred three times before the trunk finally stayed closed. A few minutes later, I parked the car, opened the door, started to get out and the warning chime sounded. I got back in and saw that the on the console shift lever that indicates your car is in park was lit up even though the car was turned off. In order to get the light to go off, I had to restart my car and then turn it off again. Next I pushed the onstar phone button and asked to call my home. I got a busy signal. I called a second time and my husband at the number I was calling, heard me telling onstar call my homeŁ but I couldn't hear him trying to talk to me. All of these things happened within 1 1/2 hours. The next day, I found that I could not lock the door by touching the lock spot on the outside door handle. Then I could not unlock the car door by pulling on the door handle when the key was in my pocket. I have had the car for 1 year and eight months and the driver's memory seat has often lost its memory. Sometimes just one button but most of the time both buttons. Prior to this I had been having trouble with my trunk. I'd leave my car parked in a public parking lot and come out to find my trunk wide open. On May 3rd the GM dealer replaced a part hoping to fix this problem.
