Cadillac CTS Engine Problems



  • natalia3natalia3 Posts: 2
    I had the same issue with my 2006 cts... but i bought it brand new and my engine blew in 2009. They said i had no oil in it so it was "my fault" (even though i had a receipt for an oil change less then 3k miles) and wouldnt fix it... they wanted $15k to replace the engine. i fought and fought with GM... no luck. Let me know if you get any response from the CEo of Cadillac!

    After our CTS had been in the shop for 1 week instead of the expected 2 days, my wife called to see what was going on. She was told they had dismantled the engine and saw excessive scoring on the engine internals. So GM has now authorized the entire engine to be replaced under the extended warranty plan. It is expected to take up to 10 for the engine to ship in to nova scotia from some GM plant in USA. So I have to say big props go to GM Canada for doing the right thing. We will keep the loaner Impala until the CTS is ready to be returned to us.

    Hope you get a new engine and not a re manufactured from some rebuilding shop. It still amazes me how Cadillac are managing to screw up building engines after so many years in the business. I keep wondering if the real source of these engines is from China or similar.
  • The dealer said it was "coming from the factory in the US" but how can we be sure lol

    Bought my cts 2005 new from a dealership here in Thunder Bay, Ontario, Canada. Put some 18 inch rims with g-force tires on it, must admit handled great! Had regular oil changes done for me and never really inquired about oil consumption, just figured oil change every 5k was more than adequate. Car was only summer driven and has less than 70000 KM (not Miles)... winters to hard up here for light rear wheel drive car like that. This morning went out to our cottage and after passing a few vehicles on route noticed power not there... turned down the tunes and heard the knocking. Quite sure the bearings gone. Thank goodness this happened when it did. Would feel pretty sick right now had me and the wife went ahead and purchased the planned new CTS. Anyone wanna buy the original 17.5" rims with tires that still have tread paint on em? :) I am sure those rims wont look good on the new Charger we plan on purchasing.
  • I am a baby boomer who likes RWD cars. Since they are rather limited in availability these days, I was interested in purchasing a 2012 Cadillac CTS. However, after reading CTS forums regarding engine seizing/oil comsumption problems with previous years of the CTS, I'm now apprehensive about buying a 2012 CTS. Now, I'm thinking maybe I should consider either the Mercedes C-Series, Mercedes E-Series, BMW 5-Series, Chrysler 300C, or even the Lincoln MKS which is FWD. Therefore, does anyone know if the Cadillac CTS engine problems still persist with the 2012 models or has it been corrected? How does anyone feel about the purchase of anyone of the above alternative vehicles to the CTS? Thanks for your help.

    stay away from the cts, they are nothing but problems, my transmission cooling lines failed and coolant mixed with transmission fluid, tranny is now acting like junk,there is no way to tell ahead of time if the lines are going to fail, raditor had to be replaced, last week tranny had to be serviced toytal cost 1000.000 and now tranny is acting up.then this morning engine check light came on.this car was babied, oil was changed faithfully every month on the 1st, regardless of the miles, now have to sell it because i cant trust it, oh and last month all 4 wheel bearing hubs were replaced because of howling noise, 1200.00. STAY AWAY,CADILLAC WILL NOT HELP YOU, EVEN THOUGH THE TRANNY COOLER LINES ARE A DESIGN FLAW.

    Dear #533. Go back to #514 (2012 CTS engine problems) and this should answer your question. You made the correct decision by avoiding Cadillac products and the poor quality they offer. I think people are catching on G.M.'s lack of commitment to their customers. B.M.W 5-Series is an excellent choice.

  • Hi David,

    Was your CTS a 2012? What do you think you will buy to replace it? Thanks for your feedback.

    I just traded in my 2008 CTS for a 2012 CTS-V Coupe.
    I never had a single problem in the 36,000 miles I drove it I only traded it in because I prefer a coupe and a car with a warranty (well maybe a little for the increase in performance)
    When I trade this car in I will buy another Cadillac.
  • I have a 2010 CTS wagon, AWD loaded with all options. 24K and no problems yet.

    Congratulations on your new CTS-V Coupe! We're wishing you many happy miles!

    I have a 2005 CTS 3.6 thats burning/using about a quart of engine oil every 1250 miles. I have less than 70k miles on it.

    I have owned about 35 GM vehicles starting with a 1970 Corvette. I have never had any of them with these kind and magnitude of problems.

    Am having Security/Theft system and Traction Control issues too. I love the car but I cant believe GM screwed this one up swo bad. I have a 2000 GMC with 197k on it and it still doesnt use a drop!

    I can't sell this car...who's gonna buy it when I tell them it burns oil and sometimes it locks itself down in your driveway a couple weeks at a time! Yikes!! I NEED HELP!!
  • Have you had an oil consumption test performed on your CTS? The accepted rate of oil consumption would be 0.946 liter (1 qt) in 3200 km (2000 mi) (this only applies to personal use vehicles, under warranty, that are driven in a non-aggressive manner and maintained in accordance with the appropriate maintenance schedule, with less than 36,000 mi).

    Sarah, GM Customer Service
  • There seem to be a lot more qualifiers than there used to be. Especially the 36000 mile qualifier.

    It would be a shame if GM intended that to signify they will only accept responsibility when the car has less than 36,000 miles. That would be a horrible PR position to take IMHO.

    We are in Canada, we had the oil consumption test done over the last 6 months, and GM recently swapped out the short block (below the head gasket, above the oil pan) for I think a factory reconditioned one. We had 105,000 KM (apx 65000 mi). It has been back three times in the 3 weeks since the fix for screeching belts, and to replace a "#6 ignition coil". It currently is making non-replicatable whooping noises that I have never heard come from a car before.

    Good luck to all of you who sufer fromthe oil consumption issue.
  • ronyxxxronyxxx Posts: 19
    Seriously??? Come on...1 quart in 2,000 miles is completely UNACCEPTABLE. I have owned about 35 GM cars and trucks in my 58 years. NONE OF THEM Including 1962, 1968, 1970 thru today have EVER used anywhere near that much oil. You guys built and sold a bad motor...own up and FIX IT!!! PLEASE!!!
    Sarah, seriously, would you buy this car from me after I disclosed all its problems to you? IM' STUCK with a LEMON...
  • zebandcozebandco Posts: 22
    Dear Sarah,

    Are you serious? I quart every 2000 miles is acceptable? Let's see GM put that in the marketing strategy. "Come on down and buy a new GM Super Scamp. Guaranteed to not to use more than 1 quart of oil every 2000 miles!" The 3.6 has a design flaw and GM's approach is to try and rationalize it. BS! I have purchased two new vehicles (not GM models) since I had the 05 STS and neither are using any noticeable amount of oil. C'mon man!

    Dear bill and ronyxxx,

  • ronyxxxronyxxx Posts: 19
    What would be point of having the oil consumption test if Cadillac wont help me? I have 67,000 miles on the car???
  • zebandcozebandco Posts: 22
    uhmmmmmm....... the point would be to document that Cadillac won't help you. It would help everyone who bought a lemon motor. Oh, yeah. And if you bought an STS you bought a lemon motor wrapped up in a $55K car.
  • GM CANADA helped me, by replacing the short block, and I had 90k kilometers when we started the oil consumption test, and over 107k kilos when they did the .
  • I was driving down the highway when my 03 Cadillac CTS with 67k miles just quit running. All the guages dropped to zero, and the battery idiot light turned on. I mangaed to get the car off on the shoulder and tried to restart the car. It would turn over but the engine would shake like crazy and with in 3 seconds the car would just turn off. Any idea what could have happend? I did have the car towed to the dealer and they are going to look at it, but I am just wondering what kind of mess I might be dealing with, any ideas at all will be great. :cry:
  • Maybe your timing chains failed like mine did and several other owners of this great car. Good Luck .
  • This is what happened to my 06 CTS - 54,066 miles on it. I was driving on I-80 in Lincoln, NE doing around 65mph and the engine just quit. I was able to pull off on to the shoulder. Had the car towed to the dealer and after several hours they told me that I needed a new timing chain..... we stayed for the weekend while they waited for parts, and on Tuesday they informed me that we needed a new engine... they said that when they started to work on the timing chain, they found concealed damage. Pistons hit the cylinder heads or something like that, and I needed a whole new engine. I had contacted GM customer service and decided to rent a car and drive to Illinois. It took over 2 months to work it out with GM Customer service, but eventually they agreed to replace it. I had all my maintenance done at the dealer, and had it done on time. I had plenty of oil when we started, but they told me I was 2 quarts low after the car broke down. Oil loss seems to be an issue. There is clearly something up with the engines.
  • V6? Probably has been low on oil and the motor ate itself from the inside out. I hope that is not the case, but read the posts here on CTS problems. Good luck!

  • My wife and I bought a 2004 CTS with 117K miles through a used car dealer with a 30 day warranty. Before the 30 days were up we had a major problem with the car sticking and knocking and the engine light coming on. The dealer said they solved the problem by installing a new 'sensor' in the transmission. This was after they assured me they checked everything in the car. Within eight weeks with no warning lights and with no problems or sounds coming from the engine, the engine blew. The tow truck operator said there was oil leaked on his flatbead and the people at PEP Boys said the car was five quarts low on oil. We barely drove the car 2000 miles since we got it and it looks like we have to replace the engine. Any ideas or comments?
  • ronyxxxronyxxx Posts: 19
    These motors are notorious oil users...see my posts and others. GM & Cadillac have their heads stuck in the sand and are denying responsibility by claiming that using a qt of oil every 2k miles is "normal". They don't realize that not only are we not going to buy any more Cadillacs, but that we are spreading the word about their's and GM's irresponsibility to their other potential customers. I talked my brother out of buying a CTS and he bought a BMW..not because mine uses oil, but because Cadillac/GM denies anything is wrong. Grow up Cadillac!!!...take responsibility for your actions!!!

    So committing fraud is o k in your book if you get the desired result? You are what's wrong with America and the worst part is that you are proud of what you did. Great example to show your kids if you have any!

    Unbelievable!! Do you actually sleep well at night?
