    I have a 2007 Cadillac CTS that after driving for 30-40 miles it will start bucking in situations where I need to eccellerate going up a hill or passing. It has started to do this when coming away from a stop sign but not as much. Has anyone else had this happen. When taken in for service, they have found no codes in the computer. They have been able to duplicate the situation slightly.
  • 2004 CTS 3.6L I have oil in my coolant. Enough to overflow the reservoir when running. I could smell coolant then saw a puddle under the car. Looks like it leaked from the overflow tube. First thought was the oil cooler. I am now being told the 3.6L 2004 does not have one. No water on dip stick or oil cap. Car did not over heat. Seems to run fine for now. Any ideas???

    I have a 2007 and it started doing the same thing after about 25K miles. Two things going on. 1) There is a software update for the Transmission Control Module (TCM) that should be applied. If that doesn't fix it, then go to 2) Replace the torque converter.
    There is a TSB out there regarding this issue. Most likely, the torque converter will need to be replaced.

    If you truly have oil in your coolant, then you have a blown gasket (head or intake manifold). DO NOT DRIVE THIS CAR! Take it to the dealer or your trusted repair shop. If you continue to drive it, you risk destroying your engine.

    Hello Diesel54,
    I am from GM Customer Service. Has the dealership put a reader in your vehicle so it can look for codes when your vehicle does have an issue? Are they currently working on the vehicle? Thank you,

    This thread is very interesting. I bought a 3.6L 2005 CTS brand new off the lot. I kept the oil changed in it at the dealer when the OLM system said until the dealer went out of business and the after that I did the oil changes at a local mechanic using Mobil 1 as suggested in the manual. I started to notice that the car was using about 1 quart of oil every 4 - 5000 miles. I spoke with a Cadillac dealer and they said this was not unusual. Then at around 75000 miles in 2008, and out of warranty it began misfiring on the way home from work and by the time I had made it home the engine was misfiring really bad and knocking really bad but no trouble light. When I was pulling into the driveway the check engine light finally came on and the oil level low warning came up. When checked the oil it was empty. Ihad checked it the previous day and it was full. I had my mechanic tow it to his shop and he found that the timing belt had jumped and bent 11 valves. I contacted Cadillac and they told me that because of the age of the vehicle and the mileage there was noting they would do. Still owing money on the car I spent the $5000 and had the valve train replaced.

    The care ran fine for about 1 year until late last it developed a knock in the lower part of the motor. I was right back to where I started from except this time it needed a new motor and still being in debt up to my eyeballs from the last repair I called around and found a mechanic that put a used motor in it for $3000.

    The bottom line is that my dream car became a nightmare. I will never get my money back on this car. A car that was $32K new has now cost me over $40k. DO NOT BY A CADILLAC!

    84K miles, changed oil and filter every 6K miles, used mobile 1, never had oil consumption problem between oil changes (yes I checked oil level approximately once a month) oil or engine light never came on, oil life @ 72%. Never any sign of oil leak or fluid on garage floor. Heard slight knock, had recently changed from Chevron to Costco gas, assumed I had water in gas, talked to mechanic said to get additive and run gas tank to near empty. Did this, knock went away. 2 days later car started knocking very loud, had car towed to mechanic, mechanic said there was no oil in car. Engine blown, replacement $8K to $10K. Seems like I am not alone?

    I had an '05 CTS that I bought new and that I sold to a friend of mine. Then I bought a new '09 last January. My first CTS has 49,000 miles so I can't verify what will happen with the engine. When I bought the '05, the dealer told me to follow the OLM. I would change the oil 7 to 8,000 miles. The dealer now tells me that I need to change the oil every 6,000 miles in the '09, which I am doing. He said that they had found that the actuators in the engine were going bad at around 50,000 from going too far between oil changes. One of my friends bought an '05 CTS which was used. He did not have it one year until the engine went out and had to be replaced. Luckily, he had bought one that was certified and Cadillac paid for it. The '09 is a dream to drive, but I only have 11,000 miles and I can't know what kind of service I will get. I am so sorry for the two of you and what you have had to spend. What I wish I knew, was how widespread this problem is.

    According to Consumer Reports, the CTS engine reliability has been better than average to much better than average except for the first model year (2003), which was worse than average. 2003-05 models have had problems with the cooling system (thrmostate, water pump), but the engine overall appears to be quite sound.

    So, these problems appear to be anomalies.

    It is interesting about the cooling system. My '05 had to have a water pump at 48,000.

    Sat., June 5, 2010 our bought new 2007 CTS 3.2 with 28,000 (28k) miles shut off while approaching an intersection here in Ft. Lauderdale. No restart, very loud grinding when the key was turned. With help, pushed it into a gas station. The Cadillac service suv arrived and Israel did exactly what I did - checked the oil then turned the key. Loud grinding. Called a tow truck, driver turned the key again - same thing. Tuesday Bayview Cadillac told us the timing chain had let go, and they were going to replace it. Checked the internet and saw it was an interference engine. Told service writer I did not want a repair, I wanted a new engine.He referred me to the service manager who said if there is other damage we'll fix it, like replacing the heads. I said no, you won't, I did not buy a used car and do not want a rebuilt engine in a 28k mile car. We want a new engine. He said it had to go through the general manager to GM, so he was to call me. I never spoke with him. A day or so later called the service writer, who told me the valve train had indeed been damaged. I repeated to him do not repair that engine, I want a new one. Stopped into Bayview Cadillac Friday afternoon, to find the engine had been repaired and the set of heads and a pile of parts on the floor. Danny the service manager lied to my face and said you never told me not to fix the car. I repeated our previous conversation and he did not deny this. Now the general manager is there and I told him I did not authorize this repair, in fact we have signed nothing since the car was brought in. His reply was you start paying for the rental car tomorrow. I left the car there and called the GM 800 number to begin a case. HEY CADILLAC, I DO NOT WANT A REBUILT MOTOR IN A 28K CAR, ARE YOU DUCKING A RECALL? And to you, Mariah, how can you deny and GM deny these CTS engines are defective? Come to Ft. Lauderdale, to Bayview, and I will show you a 28,000 mile car with a rebuilt engine I am not accepting. Anyone who considers buying a GM car after reading these horror stories is loco.

    One of the things that interests me is how gm has customer service people intercepting solvable problems but ignoring this pink elephant . One of them said they would look into my engine problem but never got back to me . Now I am willing to spend some money to do a couple of commercials with a toll-free number to see how many people had this problem . I had this exact problem and will soon see how many people the gm service advisors manipulated the warranties for to stop the number of complaints from rising . This seems to fit deceptive trade practices in my opinion . I put my car in storage and am willing to follow this to the end as gmac still expects me to make the $600.00 monthly payment.

    It's pretty obvious there is a problem here, but it appears they are just going to sweep it under the rug. When my motor went they said they would not do anything for me "based on the age and mileage of the car." So apparently their cars are only design to last 75,000 miles or so. Granted the car was 25,000 miles out of warranty but back in the early 90's I had a Dodge that had 210,000 miles on it when I traded it in and it still ran great and never burned oil.

    After parking my car in the driveway (my driveway is slighly inclined) for about 24 hours my car has a lot of trouble starting. My car will start after about 5-10 minutes of cranking it over but then it runs very rough at first. The only time I have this problem is when I park my car in the driveway. 99% of the time, my car is parked in the garage on a level surface and I have no issues starting the car. In the colder months, I can park my car ouside in the driveway 2 days before it has the "no start" issue but when the temp is mild, the problem happens within 24 hours. Yes, my gas tank was full of gas. Any clues why this is happening? My car has 58K but it has been happening for over a year now. To avoid the issue I park my car in the garage.

    My check engine light came on and I went to Autozone to have them read the codes. It said there was either a bad cam sensor or a bad crank sensor. Any idea where these are located so I can see if the connection is loose? The light came on right after driving on a bumpy road.

    hello mariah this is k9will i have two 04 cts 3.6 5speed auto i think it is trans 5l40e with a little over 90000 miles when they sit for several days when you start it then put it right in foward gear it slips will not pull at all then it softly jerks in motion and the trans works flawless after that i pay a online gm tech, and he said he thought it was the tourqe converter bypassing fluid, once he explained it to me it made sence and i just put in gear and wait for it to softly lunge in gear, also at arround 50 mph in overdrive it softly jerks but people with less experiance than me thinks it is a vibration caused by tires, and i have seen on here that gm likes to blame it on tires but myself having over 30 years in tire & auto repair buisness know that is not the case what do you think. you & i could have some fun dialoge, and if you have cadi experiance you could help a lot of people. if you respond i will tell you how i came to own 2 04 cts and one parts cts with motor & trans THANKS for your interest WILLIE

    K9Will,

    As much as I wish I could give you some suggestions on what the problem could be with your vehicle, unfortunately I don’t have the technical background to do so. The main resource that I deal with for diagnosis and technical info is the dealership so that would be the only place for me to advise you to visit.
    Thank you,

    Car # 1: My son bought an '04 CTS with approx. 40k miles on it, while away from the USA he lent it to my wife for 6 months (end of '09). My wife is very easy on her cars and we did scheduled maintenance for him. Whitin a couple of weeks returning from his trip, the car started to make grinding noise and have rough idle. The dealer where he purchased repaired under certified warranty and to date no further issues.

    Car # 2: Feb. '10 my wife buys an '05 CTS 3.6 with 49k, car fax reports 1 owner, all maintenance done. Within 1 week of buying we change oil as specified in manual. 4 months later, with no warning engine light comes on and and engine starts to shake and rattle. No warranty on this one, expired July '09, and we did not purchase extended when originaly buying the car (next biggest mistake to buying this car was not buying the warranty) Our mechanic had to tear down engine due to code for bad cam sensor, had to send heads to machine shop, replace bent cam shaft, bent valves etc. etc. etc. list of replacment parts very long.
    Total cost $2,400.00 on top of the $17,000 out the door in Feb., although my mechanic tells me the dealer would have charged me 4-5k for same repair.

    Hears the kicker to the story though, cars been out of the mechanic 3 days running better and smoother than when we purchased it and now on start up this morning for the first time I hear a grinding noise for 5 seconds and then smooth idle.

    Time for a trade in unless some attorney has read this thread and has decided to take on the GM with a class action (not an easy task, with all the money and lawyers they have)!!!!!!!!!!!!!!!!

    Keep up the bad work GM, way to go. All further purchase will be Ford/Lincoln/Mercury, just sold my 1993 Ford ranger with 250k miles on it never a major issue other than routine maintenance. Purchased a 2002 Ford Ranger with 89k should be good for another 150k easy.

    k9will did you see how fast mariah jumped off my ship but she seems nice i wish she would ck on my problem through gm service but anyway the guy with the 2 motor problems i wish i new what caused the motor to fail first then you would know which way to look, tell what part your mechanic said failed in each motor to cause the repair, a cam sensor should not cause valves to bend, run poorly yes but cause hard parts to destroy themselfs. wright back THANKS
  • gmcustsvcgmcustsvc Posts: 4,154
    Hello K9Will,
    I can assist you by getting one our agents involved at looking at your vehicle. However, they require that you take the vehicle to a dealership to have it diagnosed. If you would like me to proceed with this then I will need your contact info, VIN, current mileage, dealership, and best time to contact you emailed to me in order to proceed. You can get my email by clicking on gmcustsvc. Unfortunately what I cannot do is diagnose your vehicle over the internet. Thank you,

    hello Mariah k9will here i just read your response, my ven #1g6dm577340132801 04 ctsm 3.6 5speed auto with i think a 5l40e trans, i have a front brake line recall to take it in for anyway your idea is good but i don't want them to do some 200.00 test to tell me the trans will need to come out to fix the problem and that is how i have ended up with and extra parts car anyway, becausm if the trans has to come out i will replace it with the one that is in the parts car, so my best bet is to drive it carefully until the trans goes out completly, i also have other extra autos to drive so it is not that important that it be fixed as soon as it quites pulling thanks for your help though, unless you can get them to run test without major charge THANKS, also the gm dealership id wilson bros. inc. bardstown ky. they been great to me no complants
  • gmcustsvcgmcustsvc Posts: 4,154
    Hello K9Will,
    I cannot promise you reimbursement for the diagnostic fee. That is something that the agent would have to determine. So if you want me to set up a case for you please let me know. Thank you,
