I bought a 1999 Subaru Impreza from Shasta Nissan Subaru. On the way home, the check engine light came on. I took the car back immediately. They said, "It's your smog system. The air mass sensor is bad." I said, "It is illegal to sell a car in California with an inoperable smog system." They said, "It's your fault. We won't fix it." It drove home, and left the light on. A few weeks later, the clutch went out. According to my mechanic: "They knew the clutch was bad when they sold you the car." So, it cost me $1, 100 to fix a clutch that would have cost them $300 to fix. Now, flash forward to 5-15-08. I am visiting my son in Redding. The car starts stumbling and the check engine light was flashing. I (stupidly) took my car to Shasta Nissan Subaru. Their diagnosis: "It needs a new catalytic converter, new valve cover gaskets, new coil, new spark plugs and new plug wires. Cost-- $1, 600!!!". I called them back (they gave the message to my wife) and after some haggling, they said, "Well, you could only replace the coil, plugs and wires for $478.68". I had them replace just the coil, plugs and wires. I took the Subie to my local mechanic today. His verdict: "All you had was one bad spark plug." Cost: $3 for the plug and $85 for the labor, for a total of $88. The car did NOT need four new plugs, did NOT need a new coil, did NOT need four new plug wires. Conclusion: Never Never Never give any business to Shasta Nissan Subaru!
