My car had the rack and pinion (of the power steering) replaced in December at Sears. I began having problems with the power steering recently and took it in and was told that that the power steering fluid level was ok, there was no leak, but that they thought the pump was the problem. GMC had issued a memo about problems with the power steering pump (which GMC would cover to repair), so I brought the car into the GMC dealer with the information I was given that the pump was bad. GMC ran diagnostics, to the tune of $119.00 total, and told me that the pump was ok, and the rack and pinion was ok, but that one of the power steering hoses was leaking and that the power steering fluid level was low. The estimate for the repairs was over $600. For some reason, they ran additional diagnostics that I did not ask for, and told me that the tire struts were leaking (the car has no symptoms of this), and that a hose to the air compressor was leaking (the air conditioner swiftly cools down the car, no symptoms of this either). For a grand total estimate of over $2,000 in repairs I supposedly needed.

I took the car to Sears, because I did need the power steering problem fixed, and their phone estimate for repairing a leaking power steering hose was $300 (half the cost of GMC). At Sears, after doing diagnostics for free... they told me the power steering fluid level was fine and that they looked everywhere and could not find any leak in the hoses. They didn't understand what GMC was looking at. (Of note, I drove directly to Sears from GMC, so this was done within 30 minutes of the bogus diagnostics done at GMC). Sears then told me they believed the problem to be the rack and pinion, which they replaced for free (as it was still under warranty, having been replaced 5 months prior). The car now drives wonderfully, with the problem completely solved.

I am extremely dissatisfied with GMC, that they would 1) have such a wrong diagnosis for the problem with the power steering 2) have such a high cost to repair it. Had I gone with the recommendation from GMC, I would be out $600 with for a hose I didn't need, with a car that still didnt drive correctly due to a malfunctioning rack and pinion. I also have doubts that the other repairs they suggested (to rack up to $2000 in repairs) were in any way needed. If I do need more repairs, I will definitely not be returning to this dealer, because at best, they were incompetent to diagnose the problem, or at worst they were being dishonest and trying to rack up charges for repairs I didn't need.
