Cadillac CTS Engine Problems



  • madctsmadcts Posts: 6

    My 2008 cts had 60,000 miles on it when it happened to me. They're oil consumption guidelines are a bunch of crap. The way I started was I had them do an oil change. Then, after 3000 miles, took it back and measured what was left. It was almost 4 quarts low! The dealer then did the consumption test for nothing. (100,000 5 year warranty we all have).

    They ended up replacing all the pistons, rings, rods, the whole top end. Then they found out that all that oil in the exhaust ruined the catalytic converters. The converters came loose and jammed into the exhaust pipe. They ended up replacing everything from the heads to the tail pipe!

    They had it for 26 days! I had a rental paid by warranty.

    Take it to another dealer. It does not cost them anything if they know what they're doing.

    They just replaced the water pump last week. (Under warranty)
  • Good morning madcts,

    How is everything running on your CTS now that all of these repairs have been performed?

    Glad for you that you were so well taken care of. Mine is an '05 so out of warranty. Probably why Sarah hasn't replied to my reply to her.
  • ronyxxx,

    I hadn't replied as you did not seem interested in proceeding with your dealership; I didn't want to badger you on the issue.

    The new Government Motors is worse then the old GM.
    Timing chain issues with my 2006 SRX with 59,000 miles.
    The Blazer I sold to buy this vehicle had 160,000 miles, no drivetrain issues or any leaks.

    Your Blazer probably had an old tech 4.3 litre OHV V6. No timing belts or chains like the new tech 3.6 OHC V6 with THREE timing chains. You probably could have driven the 4.3 another 50k to 100k miles without any major engine issues. If I buy GM, it will only be an OHV engine. This means a full size pickup or used car because GM in it's infinite wisdom stop producing its most reliable engines (e.g. 3800 V6). GM hasn't shown it can build a reliable OHC engine. Good luck.
  • Hi,

    Did you ever find out what was wrong with your vehicle? I am experiencing something very similar. My car has cut out on me 4 times (no lights, no steering, no brakes, NO WARNING). The dealer cannot seem to recreate the issue and I am not sure what to do. I purchased the car new (December 2011), so it's not even 1 year old. I need some guideance, so any feedback you can provide will be helpful.

    Thanks! :lemon:
  • Firstnotlast,
    Not sure I have a complete answer for you. I had one Cadillac dealership look at it in Waldorf, MD (not where I bought the car but closer to my home). They had the same problem you did which was not able to recreate the problem. I then took the car to the Cadillac dealership in Greenbelt, MD where I bought the car. They also inspected it top to bottom and were not able to recreate the problem. The problem happened to me 3 times in all since I bought the car at random situations and times. It has not happened to me (knock on wood) since I got the car back from the latest visit. My only thought is that all the inspecting/tightening of all connections from the two dealership visits fixed the problem. If the dealership did not do this, ask them to go through the engine/electrical and tighten/check every connection that could cause this. Maybe this alone will be a solution as it seems for me thus far.

    I was driving a 1998 Honda Accord with 165k miles on it when I decided to buy the CTS with 58k miles. Here is a nice laundry list of repairs one can expect when owning this car:

    03/30/07 - Check service stability system - Diagnosis: replace steering wheel position sensor $262.28 - 61,687 miles

    09/07/2007 - Can't turn car - Diagnosis: Power steering pump failed - $688.51 - 67,235 miles

    09/07/2007 - Noise in rear end at low speeds - Diagnosis: Gears failed, replace carrier assebly - $1307.94

    06/24/2010 - Excessive play in front end - Diagnosis: Replace left front tie rod - $260 - 84,304 miles

    08/23/10 - rear pinion seal leaking - Diagnosis: replace - $264 - 86,009 *also checked for engine oil leak, couldn't tell what it was. See 10/5/12 issue

    03/2011 - Car wont move, spewing fluid, have to tow to dealer - Diagnosis: Coolant line blew, radiator replacement - $667 - 90,000 miles

    07/1/11 - Humming noise in rear end - Diagnosis: replace right rear hub & bearing assembly - $826.68 - 95,295 miles

    03/2012 - Did recommmended 100k tune up - Normal wear and tear but wanted to make sure everyone knows I take care of the vehicle. Also have changed engine oil every 6,000 miles since I have had it.

    10/05/12 - Thud in front left - Diagnosis: replace left front strut - $354 - 111,203

    10/05/12 - Oil leaking from engine - Diagnosis: $5 part failed, replace oil filter adapter gasket - $302 - 111,203

    Currently: 112,000 miles and check engine light is on. The vehicle in not reaching operating temperature Diagnosis: replace thermostat - $700
    Currently: Got stranded on highway cause vehicle ran out of gas, however, not my fault. Tank read 1/4 tank left. Fuel sender is faulty which also has a TSB out there that they manufactured with a faulty part (siphon hose) - Cost to drop tank and replace is $700.

    Needless to say, my honda had one repair from the 60k to 165k I drove it. EGR valves had issues. This CTS has been an absolute lemon so if you are looking to purchase, look forward to taking an additional loan out on the vehicle to the tune of about $6,300.

    Enjoy! Greg. - 40133811

    You're my kind of person. Where I work they call what you just posted "objective evidence."

    I went off the reservation (mine anyway) 13 years ago and bought an American car that attempted to compete with Europeans. Prior to that I'd owned mostly Asian vehicles. My current daily driver is an Acura, and my wife drives a Nissan product.

    Your list is why, though the CTS is in a class by itself in terms of money pit potential. At least you haven't suffered the dreaded oil loss engine failure. Many who post here have.

    You still have that to look forward to. Let us know.

    Unbelievable repair record. Thanks for sharing in such detail. The problem is, when you start the repair process, you think with each repair that this will be the end of it. As you get further along, you have invested so much in the vehicle that it makes less economic sense to trade it.
  • although I do not own a Cadillac I keep wondering how their cars came to be such lemons. They were once known for engineering excellence and forward thinking. Its too bad this once prestigious brand has come to this and if it were not for loyal customers the brand would have died long ago.

    My 2012 CTS stopped dead at 60 mph on a highway in New York the same month I bought it. The only reason I did not have an accident was that it happened in the middle of the day on a holiday. Otherwise, the highway would have been jammed. The dealer kept the car a few days and said they could not reproduce the problem and would look at it if the problem happened again. The dealer said the problem was probably a "software glitch." I have been in the software industry for 30 years and have never heard of such a thing. Besides, if there was a problem with the software, it would occur in other vehicles with the same software. Not wanting to take my life in my hands, I sold the car to another dealer and bought a new Acura, which has performed great! I told the dealer about the CTS problem, and it appears from the subsequent OnStar reports that I received that the CTS was not sold for many, many months. I assume the cutout happened again, and the dealer was trying to get it fixed. I will never buy a GM car again!
  • You are spot on. I think it's funny how the GM customer service is non-existent in response to my post and through the repair process.

    GM will become solely a truck company in a few years because no one will buy their cars. With social media, the bad word will get around about the unreliability of their cars and the only vehicles GM will be able to sell will be Silverados, Sierras and Tahoes. Bankruptcy maybe just around the corner again. Just saying.
  • i just bought a 2005 cts with the 3.6l in it, i would have never, if i knew of the problem with the didnt not leak oil anywhere or use it to my knowledge when i bought the car july 12 of this year(2012) and it only came with a 3 month or 3,000 mile warranty and as far as i knew cadillac has a great reputation and what not. so i didnt buy the extended warranty. well needless to say i put almost 4,000 miles on the car in 2 months and 12 days after i bought it and the car is blown up, still havent got it fixed because of this problem and i still owe just under$10,000 on it. i called dealership and they only wanna give me up to $1,000 to help with the repairs when they said originally that they would cover all parts costs if i would pay for that the used motor is gonna be $2,000 plus they dont wanna top it off to make sure that the motor had spun a bearing they had car towed to the dealership and then made me pay a partial fee to tow it back to my house becuase i wasnt getiing it fixed there. now when i do get the car fixed i am gonna sell it as soon as i can or trade it in because its gonna be a huge headache!!! is there anything GM can do or is there a recall yet or maybe a class aaction law suit is in order because i am sure that all these people with complaints are gonna win including me,why continue to see a car with a motor that conitinues to have problems!!!!!!!????????!!!!!
