Had 1994 Jeep GC Laredo serviced at Wharton's in Parkersburg, WV., and was ripped off, several years ago. I diagnosed problem as a faulty crank position sensor; vehicle would run for 15 minutes then shut down, no spark at coil. Would restart after one hour cool down. Common problem according to Jeep forum posters I interacted with. Was stuck in West Virginia. Couldn't access sensor with limited tools that my friend had. Tried to get in at local mechanics, but all were booked up. Had to get home, so in desperation, called Wharton's and left vehicle there, then rented a car to get home. I called them several days later, and my diagnosis was correct. CPS was bad. Would cost ~$170.00 to fix. I give "OK." They called me back several hours later, said still having problems after replacing CPS, that the CPS may have damaged the computer. Replacement would be $800.00. From having some knowledge of doing my own car repairs, I knew this was BS, as a CPS is a hall sensor, passive and unpowered. It would not cause damage to DME system. I told them so, and they said if they don't replace computer, vehicle will not be fixed. They said they can get a used part, but won't guarantee it. Called me back next day, said they found used part for ~$350.00. Being 300 miles away and desperate to get my girlfriend's truck back, I say "fine." We picked the truck up that Saturday, only sales people present, but they released the Jeep to us. Got it home and looked at the cowling covering the computer, and it had never been removed! It was covered in grime and the bolt heads had never been touched. The dirt and grease on the bolt heads and the cover was totally undisturbed. Not a single smudge in the dirt. Amazing! I took the cover off and the "new" computer didn't even have a fingerprint on it. Bottom line; it was NEVER replaced. I had bigger projects going on at that time, so I never contacted them to complain, not wanting to drive another 600 miles to have them "look at it." Personally, I wouldn't take my dirty laundry there. If you have your vehicle serviced there, be very wary of the sudden 'add-on' surprises, and find a way to mark the parts that they say they're going to replace.
