Very strange story here. Bought at a very cheap price last weekend a new 2018 LT (7 miles) that had been sitting on the lot for about six months.

As we were preparing to drive the car home from the dealership for the first time, the check engine light went on.

They brought the car to the service department and then a few days later, after consulting with GM in Detroit, told me it needed a brand new transmission. They are installing it now.

I’ve verified that it is not a rebuilt transmission, and that they’re putting in a brand new Volt G2 transmission.

The service manager did tell me that it’s pretty involved — they obviously have to take a lot apart a lot of different things to get to the transmission, remove and replace it, then put it all back together.

Obviously I’m getting the regular new car warranty with this: three years bumper-to-bumper, six years drivetrain, eight years on voltec.

Is anyone thinking that I should be asking for any kind of additional coverage?

I assume other than losing a week on the warranty while they were replacing the brand new transmission with another brand new transmission, I’m going to have the same warranty that I would’ve had if I would’ve just driven it straight home.

The only thing that concerns me of course is that they have to take a lot of the car apart to replace the transmission, so just looking for some thoughts on this.

The deal on the car was really quite exceptional, so I don’t want to walk away from this if I can avoid it.

Thanks

I'd ask them to toss in a trunk mat or all weather floor mats with the car as a "sorry" for you being without the car for a week while you're paying for it.

They might do a tiny extended GM warranty, but I don't know how feasible that would be to really extend the coverage on the trans since it actually requires a fairly expensive plan to really push past the powertrain warranty period. Probably too much to ask for free if the deal is really as smoking as you say it is.

YMMV, but you can only get something if you ask for it.

Thanks. Yes it should be 8 years on tranny just worried about the rest of the car since they have to disassemble a lot. I’m calling GM in Detroit now to see what they will do first. It is really not the dealer’s fault.

I'd probably try to get the car's in-service date reset to when you actually can drive it off the dealership's lot.

Update: Well since I had to wait 3 weeks for the repair and delivery of the car and they had to remove so much to replace the tranny GM extended the b2b warranty to 5 years 100k.

Got this notice just hours before they announced the end of the Volt.

Had my tranny replaced within weeks of getting the car. No failure, just the check engine light and a failure of a sensor inside. Took them a full week to replace the tranny because they need to pull the engine cradle out of the car. Took a couple of returns afterwards to fix up some post dealer workmanship issues associated with such a big job. Warranty charge was $10k. Three years later everything is still ok. Mine was one of the first of the G2 units made.

After they were done they kept it for a few more days and checked and drove it about 80 miles over several cycles to further check it out. They had to burp the coolant line to fix the cabin heat. All seems ok for now.
