2007 Cadillac CTS transmission problems

Filed May 12, 2026 · Electrical, Transmission · PA

Vehicle primarily failed while parked at owner residence [XXX] and remained inoperable for approximately three weeks prior to tow to Cadillac dealership. The ignition key became trapped and could not be removed. A manual override release beneath the driver-side steering column was required to free the key — confirming the lock was held electronically, not mechanically jammed. Fault confirmed by authorized Cadillac dealer: intermittent electrical fault within the shifter assembly lock mechanism. A similar intermittent concern was previously documented on this vehicle in 2011 (logged as "Customer Concern Not Duplicated"), establishing a recurring pattern. GM Technical Service Bulletin 07-07-30-032D (2006–2011 Cadillac CTS, automatic transmission) explicitly documents this exact condition: key sticking, Shift to Park DIC message, shifter binding, and battery drain. OEM replacement part is now discontinued. Manufacturer declined goodwill or recall coverage. Dealer refuses repair unless owner assumes full financial responsibility for a used part with no warranty and no guarantee against recurrence. Safety concern: ignition/shift interlock failure causing vehicle immobilization, key entrapment, and loss of transportation for an elderly owner dependent on the vehicle for medical care. Defect evades shop diagnosis due to intermittency. No safe OEM remedy exists. Prior recall: the federal safety agency 14V394000 / GM Campaign 14172 addressed same interlock system. Current failure represents recurrence beyond that recall's scope. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The seller lied about everything! The first question I asked was if the car was in an accident. He bragged about being a mechanic, and doing all the work on the car, so everything in the car is in, "tip top shape." he replied, "no, never!" he did not allow us to ride the car on the interstate before the purchase, claiming it was illegal. 10 mins after leaving the car lot, the car cuts off and is unable to crank back up. The seller meets us and claims it the battery. A "new" battery was placed in the vehicle, but the problem persists. My fianc, who is not a mechanic, told him more than once, that the problem was not the battery, but the alternator. He got the car to crank. As we are riding down the interstate, the car cuts off, and we are left aimlessly rolling and are unable to control the wheel. Plus, the electricity in the car is off so we can't even turn on our hazard lights to caution the other cars on the road. After speaking to the seller, once again, he tells us there is nothing he can do about it and will not cancel the deal. We've only had the car for 4-5 hours. After speaking to several mechanics, they quickly confirm that the alternator is the problem and anybody that claims to be a mechanic can see the problem immediately. They also inform us the car has been wrecked and should have not been resold for safety measures. Driving this vehicle almost cost us our lives.

The car is running like it is stuck in some kind of safety mode. It does not want to accelerate unless it starts accelerating in third gear. It does not come out of 3rd gear at all. The engine light and airbag lights are lit up on the dash. There is a couple of recalls listed for the same exact year make and model but it says that this VIN number is not under recall. I think that this vehicle needs to be inspected to see if it actually does need to be listed under those recalls. It is not just this one specific VIN number having these issues either. I have talked to quite a few cadillac owners that are having the same problems and their vehicles are not listed under those recalls either. If you turn on the car you put it into drive the car remains stuck in 3rd gear and will not shift through the gears properly.

I am the owner of this 2007 gm product. I took my car to frankel cadillac 1/09/15 , invoice number 60596 and I was never notified that there were recommended recalls on my vehicle. On that date there were some problems related to the wiring on the ABS and ebtm and I denied the service to be done there because I was quoted a cost of over 2,500 dollars and I was informed that it might escalate to 3500 if an ABS pump needed to be replaced also. I later had the work done at young's located in woodlawn for a lot less. I now problems with the power train and the anti theft system and have the auto in gregg's repair , 5050 wabash ave. I also saw on line that the on star operation is able to release the anti theft mode. I have been quoted a price of 886 dollars plus change by gregg's cadillac . I am able to drive the vehicle, but in order to get the key out, the battery has to be disconnected. I am perplexed that I was never notified about the recalls on this vehicle. With all of the noted problems I was in motion. I was stopped by the police for the brake light in the city and I was driving on the highway when the anti theft mode went into operation.

2007 cadillac cts began making a loud humming noise. Had the rear driver side wheel bearing changed but the noise continued. On way home from work the following day on i75 driving 70mph which is the speed limit, the car started making a loud clunking sound and was nearly impossible to steer. Nearly had accident while trying to get to shoulder of road. Was informed by mechanic that "the rear end went out of your car because you didn't have any differential fluid left in it" when I asked how that could happen the mechanic said there must have been a leak of some kind. Started researching and found there was a recall on the car 4 years before I purchased it. When I called gm at 800‑458‑8006 I was told by automated phone system there is an open recall on my vehicle #07204e and 10355c so asked to speak with a representative and the lady from manilla in the philippines (because that's where their customer care center is???) informed me that there is "no open recall on your car" even after I tried to explain the automated service had just given me 2 open recall numbers for my VIN # ...she said she couldn't help me find service for my car.

For the last year my car has ran badly. Very rough idle, engine light throwing multiple codes, bad gas mileage, heavy oil consumption, and pulsating throttle while parked and driving. I've taken it to the dealership and for an entire year they've given me the runaround. On monday I took it back in to rancho motor company in victorville, california and they finally say it's the timing chain. The recall warranty voided at 120000 miles. Now they refuse to honor the recall. My car is dangerous to drive.
