Yeah, it's definitely going to be more accurate, which is probably why the Cadillacs use it. If the vehicle has run-flat tires like the Corvette, though, it needs a system like that - otherwise you might not notice if you had a flat tire..
You must live on the boonies if you have to leave you vehicle all day. Any dealership worth their salt today has a fast lub facility, that easily competes with the others, with more competent people working on your vehicle.
No. I live 3.5 miles away from one dealership, but I live only three blocks from an oil change shop. There is nothing wrong with the dealership as long as you like their business practices and red tape.
"Make an appointment" ( usually "next week" ) "Leave the car for the day"
And for warranty work, it might or might not get fixed. I think it was their way to discourage customer returns.
I still remember one Chevy dealer; ( my engine check light was lit ) I made the appointment, dropped off the car ( bummed a ride with my buddy ) bummed a ride to work the next day.... and the next day bummed a ride down to the dealers. ( they claimed they replaced ??? ) Picked up my car in the dealers lot On the way out, "ENGINE CHECK LIGHT" drove it back in to the bay...... "Leave the car" !!
Correct...on average....about 40% less then CP (customer pay) work.
Some warranty work is great, other operations are terrible. A couple of quick examples: Replacing pistons on Malibu engines pays 13.7 hrs, can easily be done in 7 hrs. Case half leaks on the Cadillac Northstar engines pay (older style) 11.7 hrs, and you have to kick ass to get it done in 8-9 hrs. Most techs cannot do a case half repair in under 15 hrs so most aren't interested in doing that repair. And this is exactly what happens, known "bad" work will simply "not be noticed", while known "gravy" operations will be brought to the attention of the customer. Sometimes it's GM that brings the hammer down and directs us "not" to "notice" certain things.
Some stuff is weird, I just did two rear park brake cables on a Cadillac a few days ago. Left cable pays .4, right cable pays .4, replace both cables is .4......... that really makes a lot of sense.
Brake work actually pays better under warranty times, but that is simply because the industry has artificially lowered labor times on brake work to the paying customer. If you went by book times for brake work, you would be far out of the ball park in labor costs that no one would get brakes done at the dealer. As it is now, there is very little, if any, profit made on a routine brake job. For the tech it's profitable, but not as much for the dealership.
Even if that were true, what does that have to do with a dealership not wanting to do warranty work, that is free to the vehicle owner and paid by the manufacture? Do do think they would rather not do the warranty work and get paid nothing?
Let me state an example. Suppose the labor rate is $100 per hour for customer work, and it is $70 per hour for GM warranty work. However, the shop has to pay the technicians and mechanics the same $25 per hour, and they have only a given number of qualified staff.
Chances are the shop will take all of the customer work that they can get, and then they will take only as much of the warranty work as they have excess labor available for. If they start taking unlimited warranty work, then their staff might not be able to effectively finish all of the customer work. So, it is a priority system with top priority given to the highest paying work.
If they had unlimited staff, then they would do all of the work of both kinds. But then they would have much more labor overhead and probably waste and inefficiency.
