I will if you will....
Here goes:
Bought 5/18 with 24,000 mi. at a Buick/GMC dealership an hour from home.
6/18 chose to go to the Cadillac dealership closest to me for CUE screen (already?) and service. Also replaced a defective armrest.
11/18 28,xxx miles. Bought snow tires, requested frt cover oil leak repair - done. Trans shudder and a/c control issue - NPF.
12/18, 100 miles later, died on the road. Teardown revealed broken crank gear. I know that was caused during oil leak repair but can't prove it. Should have gotten a motor but they chose to repair it. Crank, gear, chain, all pistons and valves. I was pissed. Trans and a/c control NPF again. Had to go back for a coolant leak,and they had put my directional snow tires on backwards.
4/19 30,500 miles. Bought summer tires and they damaged all 4 rims. I can't take the trans anymore - try again. According to the TSB that still required test/measurements of shudder, it wasn't severe enough, therefore no fix. Calls to Cadillac were a waste of time. Took service mgr for a ride to get his agreement it has a problem. He agreed to proceed with the rest of the TSB (I found out later they didn't).
Also had a ticking noise in the firewall/dash area to check out. Turned out to be HP fuel pump and was told there was damage to cam and head. Now I was really pissed that they didn't replace the motor in December. They replaced it this time. And "refinished" my rims. And it only took them 6-7 weeks. That's right, I got my car back in June.
And they sent me home with an empty coolant tank and a qt low on oil. In my brand new motor. Oh, replaced shifter ass'y also. Kept getting "shift to park" message and RAP wouldn't shut off until I smacked the shifter!
All told, in a year and a month, my car was in service for nearly 90 days. Thank god for warranty and loaners. Too bad about my choice of dealership.
Anyway, went to another dealer that's been great to me. Took a couple trips, but a/c was fixed with temp actuators, they did the trans flush/TCM relearn which has been pretty good (not 100% but I don't blame them), and replaced the rear driveshaft that had some runout. They swapped my snow tires most recently and road-force balanced them. Got 4w alignment (subframe's been out of the thing twice and I know the nummies that did it didn't align it after) and car now rides and drives better than when I bought it.
Finally.
And it still only has 35,xxx miles on it now, but I'm liking it again!
