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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Is or was or has this car had any recalls. For a 2006 veh with only 54,104 miles on it and have to put out the money to pay for work on a car with electrical problems, so far (intercontrol module) is not right. This problem caused the whole car to not respond at all (in luck we were at home when this happened)but, if we were gone it could have been a disaster if this would have happened while driving it shuts the whole car down, this is a disaster waiting to happen. Please help

Impala 8-cyl

  • 24,000 miles
2006 Impala ss, 5.3L V8. Excessive oil consumption; 1 qt every 1,200 - 1,500 miles. Problem started before car reached manufacturer 3 year 36000 mile warranty. Dealer replaced valve covers to repair what were believed to be faulty PCV valves integrated into valve covers. Oil consumption continues. Dealer now wants to clean upper part of engine to open oil flow ports, still indicating oil is accumulating under valve covers and being pulled back into engine thru PCV valve. Dealer has never performed compression test to determine if problem is really related to combustion chamber problems, such as bad piston rings. Dealer has reported that this is a common problem on Silverado pickup trucks with the same 5.3L V8 engine block. Car now has 51000 miles and problem has not been solved. Car will be going back to dealer with a demand for a compression check.
