heres a post from a member from a previous discussion about gm and imports..
"ArticSteve is correct....I'm an auto engineer, and have dealt extensively with those in the industry. Nearly everytime we have a discussion about a part with a domestic builder, they say "this part/process has to be cheaper". Period. The domestic are absolutely loathed by the parts suppliers and tier suppliers alike. When we talk to the Japanese builder they say: "this part has to be better while maintaining cost". Big difference. In one instance that I am aware of, the supplier believed they would be unable to improve product while maintaining cost. They would have had to hire more engineers. Instead, the manufacturer "loaned" several engineers free of charge to the supplier to help them meet the goals.
Further, we had a Cadillac part (which I showed to Wing when he visited one of the shops with me) which Cadillac decided to have built in China (which the Big 3, but especially GM seem to be doing plenty of. Yet they tell us to buy domestic, right?) While China has cheap labour costs compared to us (Chinese labour "shop rate" is about $12/hour compared to about $65/hour for our Canadian shops) their level of skilled trades isn't even remotely close to ours. Mainly because they have been making trinkets for the last 50 years, not specialized skilled trade type products. At any rate, the Cadillac part was so poorly made, that GM contacted us to repair it, and the repair bill from us exceeded the initial cost of the tool itself!! I can't be sure how many poorly make products slip through the GM QC process. But because this tool cost twice what it was supposed to, that means GM will be cutting corners somewhere else to recoup this cost.
Acura and Lexus are both very, very picky about their parts. I recall Lexus scrap policy was a mere 10 parts per 100,000. If 10 were bad, the entire lot was scraped. They've often visited the shop while the tool is in progress to see how it is going. We never see people from the Big 3 drop by to check progress...they usually drop by to complain about cost. In addition, Nissan makes regular trips to shops, not to check on any specific job in progress, but to make sure the shop is still up to their standards for cleanliness and functionality.
Most people think I'm just hating on the Big 3. It because I work closely with them, and I know how stuff is done and how corners are cut at their behest. Their quality can't match that of the imports.
