I am considering trading my '02 Buick Lesabre for a '05 CTS. Are there any known problems with this vehicle. I did find a site that suggested the rear diff. was weak, but that was on first year (2003) models and has since been addressed. Anything else I should know about. It has 70000 kms (43000 miles). It was an Enterprise lease/rental from California. Any info much appreciated.

Biggest problem with CTS is that you will love it; very reliable, quick, safe, etc.

It will not have the ride of the LeSabre, but life is tough. BTW, your LeSabre will give you about 200,000 miles. No built in problems with those cars. (America'a best kept secret; keep it for a child or grand child.)

Most of the Buicks of that gen are bulletproof. A friend just recently got rid of his supercharged regal, had over 240,000 miles. The best thing he ever did for that car was get rid of the stock 7 degrees of KR right from the factory. A tune and breathing mods netted him a low 14 1/4 and about 5 mpg better. Great cars only let down by so-so interiors are strong but somewhat overwhelmed trans. He was making 310 whp+ for the last 90,000 miles, too.

I have an 05 with the 3.6l and I have more than 102k miles on the odometer and still LOVE the car.

-The differential is still running strong. (yes it couldd be a problem but I guess its a 50-50 problem. Mine is still in good shape and I change the fluid every 62k miles)
-I changed the sunroof switch (48$) because it was faulty.
-the rest is maintenance.

- The biggest problem you'll find with the car: you will not want to sell it and you'll fall more in love with the car.

Thanks for all the feedback-especially about the Buick. I has been a great car, but the I saw the CTS at a real good price, so I thought I would look into it. It does drive real well. Thanks again. Will post if I finalize.

Here's my take on not one, but Two 05' CTS's...a "His & Hers"!!! :thumbsup:

Other than a few minor -in warranty- issues (trunk shocks, rear air bag covers, rear bumper clips), these 05' CTS's (Luxury & Luxury/Sport) are Great Pre-Owned Deals!!! :blurock:

Take the proposed CTS to a Cadillac service mgr and ask him or his (heavy equipment) mechanic test drive the car and REAR END for noise, reliability, etc. If the car is still under warranty, ask service mgr if warranty covers a repair like that (noise). (Manufacts are now requiring actual breakage before warr kicks in.)

(essentially a second opinion away from the selling dealer)
