Arrowhead Cadillac

I had my '08 STS towed there due to a 'no run' condition after some engine maintenance. They tinkered with the car for three days, then sold me a rebuilt ECU ($1400) that I didn't need, as it eventually turned out not to be the problem.

When the replacement ECU didn't make any difference, they concluded that we needed a replacement crankshaft position sensor. At this point, I dismissed them. I had previously tested the sensor and found it to be functioning. I informed them about this in writing when the car was delivered to them.

After a week and a bill for over $2700, I had the car towed back to my house, with it still not running. It turned out that the serpentine belt ($25) was worn out, causing the alternator to provide insufficient power to keep the ECU alive. So, after their 'experts' wasted a week of my time and over $2700, I had to fix it myself by replacing the belt. Absolutely no service was provided and I am out the towing charges to move the vehicle to and from this dealer.

Management made no effort to rectify this error. Barring a satisfactory resolution through the BBB, I will have to resort to litigation.

Clearly, Mister Goodwrench does not work at the Arrowhead Cadillac service department. They lack technical talent and wouldn't have been able to diagnose this relatively simple problem.
