A warning light came on in my Odyssey recently. The manual said the light meant it either needed a new catalytic converter or the gas cap was loose or defective. I took it to Superstition to have it checked out. The service guy told me it would be a $400 repair. Having spent more than $4,000 on recent repairs at Superstition, I guess they thought I would go along with anything they said. I tried tightening the gas cap and a day later the warning light went off and it has not come back on since. I'm not saying they are crooks but I definitely won't be going back there again.
