Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My SC430 has had a strong sulfur smell from the exhaust system (after medium to heavy acceleration) since it was new. When I first mentioned it to the service department they told me I needed to put a few thousand miles on it and it should go away. I gave it several thousand miles and it didn't help. They then checked it out and told me they couldn't find a problem and referred me to a service bulletin that said I should try a different brand of fuel. I tried every brand of fuel sold in my area (chevron, union 76, shell, mobile, texaco, arco, astro, etc.) and none of them made any difference. …”
