In your April 8 article "Toyota broadens sludge-repair program," the automaker insists that owner negligence is the cause of the problem.
For more than a year, I have been the spokesperson for hundreds of networking owners on the Internet. Those owners have not been shown any test results by Toyota that confirm that.
If what Toyota says is true, why have some owners with proof of proper oil change intervals been flatly denied warranty coverage, even in corporate-sponsored arbitration when sludge has occurred in their engines?
If that is so, why are Toyota dealerships recommending 3,000-mile oil-change intervals rather than the interval specified in the owner's manual? If that is so, why are only specific Toyota vehicles involved in this new program?
If this is only a matter of owner neglect, why is the PCV system being modified? Why is a new engine cam cover, which has larger holes to improve the flow of oil, being used on the V-6 engines? Why has the engine block been changed on the Camry four-cylinder model beginning in 2002?
These questions remain unanswered. Without the answers, I hardly think that Toyota can make a blanket statement incriminating the owners of those vehicles. Is this exclusively a matter of maintenance, or is it more, as some experts claim? I strongly believe it is the latter.
