CT4-V Frustration with build quality

[GoPlz]

I wish I could report something different, but I'm at the mercy of GM who don't want to give authorization for a new trans yet. Maybe once he cracks the case they will change their minds, but it sounds like not before.

You are not at their mercy. You can and should insist on a complete replacement. They should not be rebuilding the transmission at the dealer's shop. The should install a new unit and they positively do that. I would absolutely not accept a shop based internal part replacement.

Replacing the whole transmission might be done to reduce service department complexity, but a big reason is GM doesn't know what other damage or alignment issues might be there with an internal part that needs replacing. The only safe way for GM to know the repair will not have other issues is to replace the entire assembly.

I'd ask for the credentials of the tech doing the work. They may sub it out to a local transmission shop as well, but for a new car under a luxury moniker, I'm less than thrilled on your behalf. This isn't a Chevy Cruze.

Do the "certified V" techs even learn how to rebuild our trans?

 

[Melon]

I wouldn't imagine most dealerships mess with it. The cost in labor to do the work is probably more than a new unit at wholesale.

Transmission rebuilding is a specialty skill in the automotive industry. It's not impossible but, I'd think unlikely.

Little update for those who might wonder. Dealership has ordered a left side turbo and the synchros for 2nd gear. Parts are on backorder, with no ETA.

Mine makes the same chirp noise. Honestly, I've read it's nothing but a nuisance and not really an issue if you can live with it. Is this still true or is there a true mechanical reason to replace it?

I imagine one could live with it, as it doesn't seem to have any performance issues, but I don't want to. It's sad having such a nice car making such a ridiculous sound.

I agree. My concern is knowing some of these dealers service areas are hacks, I don't want to trade one problem for another. Seems like invasive surgery to replace it?

I couldn't get the video to play (they block a lot of things at work) so I didn't hear it, but I wonder if perhaps it's the blow-off valve?

Unfortunately it's not the BOV, it's a loud chirping on throttle tip in for a split second

"Certified V" is the dealership paid to send their staff to Spring Mountain for a few days and play with Blackwings. It's a sales certification. What you should probably care about is the tech World Class certified.

10 weeks my car has been torn apart now. This, after 3 weeks in their shop initially for diagnosis. Driver's side turbo was replaced and the transmission is finally going back together with a new second gear synchro. Cadillac is hinting they will buy my car back, but I waited so long to get it I don't want to go through the process again. I've asked they provide me an extended warranty and reimburse my monthly payments for down-time instead.

Just sucks that my 7,200 mile car has spent almost a third of its life in the shop.

GET THEM TO BUY IT BACK!!!!
Remember the person rebuilding it DOESN’T DO IT EVERYDAY!!!!
If it was mine I’d cut deal for new built ASAP and GM would do it, they don’t want any more bad news!

I agree, take the buy back and start over. Covid is over and the goat pen is empty.

I'm no expert here (duh, says everyone) but it appears that it's really not very difficult to obtain a CT4 these days. Go for the buyback if you can.

And yes, it's a shame that you've had to go through all of this, and I feel your pain. Best of luck!

They're more available on lots, but if you want a custom order you'll be waiting a while unless you can swing a purchase in Texas which seems to be where about 80% of all Cadillacs are delivered.

That's where mine came from. Almost 6 months waiting and I went to Dallas to pick it up. My Coastal Blue over Tan with Bronze wheels won't be sitting on a lot anywhere, so it will be back to the long wait again.

I've spent a lot of time hunting for a CT4 BW, if you want an Auto there are a lot out there. Wheels could easily be swapped, but interior and sunroof options are obviously not easy to deal with.
If you want a manual you better not be picky, there are so few.
From what I've seen most dealer lot units have a sunroof. Tan doesn't seem very popular, white high performance seats or basic black seats are pretty common. Lots of cars are black, white and gray/silver and not many coastal blue, but there are some and they seem to either have the standard wheel or the bronze wheel when you find them.

This 100%. While I've been waiting I've tried to look at dealer inventory and it's just depressing what they think people want to buy. There's so many good color combos but apparently Americans just want black, white, or grey with a boring all black interior. I guess if you swap out cars every other year it isn't as big of a deal, but I plan to drive mine until the wheels fall off.
