Looking for some advice about how to deal with my mechanic and some repairs. I have a 98 GMC Savannah with a diesel engine that I use once a week during the summer to make deliveries. Last fall, one of the batteries died. It took us a bit to find the frame battery, but we did and after some tinkering, my husband replaced the battery. The van ran fine all spring – we probably drove it 5 times, and then, on one trip, the van died at an intersection while my husband was driving. He said it sputtered and then a minute or two later died and he couldn’t get it restarted – and that the voltage meter was reading low. So we had it towed to our mechanic. I mentioned the recently replaced battery, they said that was the problem – that the bolts had been stripped and they would go ahead and replace the posts, etc. I asked if they were sure it wasn’t something electrical draining the new battery – they said nope, my husband had definitely botched the job. So they fix it, and when they’re test driving it, the tech goes to park it, the engine surges, the tech turns off the engine and then can’t get it started again. They said it had codes indicating that there was a problem with the fuel injector. They said it was burned out and needed to be replaced – and that it was probably caused by running the van on a bad battery. So we told them to replace it. By this time, 3 weeks have gone by, and we have a bill for $3300. They test it, we pick it up, and on the way home, the van dies at an intersection. We have it towed back to the mechanic, and they tell me that it had a weird electrical problem and they’re looking into it. I ask if gave them any codes. They told me that it was giving a code for the fuel injector again, but that clearly wasn’t the problem. After another week, they said that the fuse box had its rain shields removed and was completely corroded and that it would need to be reconditioned or replaced with a used one because it’s no longer in production. They said at this point, it was all labor and it could cost a couple hundred or a couple thousand depending on how long it takes.
What do I do? They’ve had the van for a month and we’ve paid them $3300 and it seems like the problem is unsolved. Does what they’re telling me seem plausible? That they fixed the battery and found the injector problem which then in turn uncovered the electrical problem? It seems like the electrical was always the problem and I paid for a fuel injector that I didn’t need. Should I try to get them to cover the cost of the repair? Is that unreasonable?
Sorry if this was a little incoherent – just need a little advice. Thanks in advance.
