Differential Unit problems of the 2007 Cadillac CTS

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.

On 4/02/2015 I was driving my vehicle when suddenly I heard a explosion type sound and it would not move. I was doing approximately 30 to 35 mph. I pulled to the side of the road to inspect the vehicle when I saw oil coming out from the back of the car I called aaa and they towed me to my home were I did research and found that Cadillac Cts from 2005-2007 were having problems with the rear differential. So I contacted Cadillac div. Directly and was given a case # 71-1463000661 they contacted coral Cadillac dealer and they came picked up my car and had it inspected they confirmed that the car has powertrain problems but the mechanic says that there is a possibility they will not cover the fees to repair it due to the VIN # of my vehicle does not have a recall for that issue> at this point I do not understand my car has experienced everything in the original recall for that make, model and year. Please help. . . . .

I am concerned about a know differential issue with the Cadillac Cts. In forums every where I am reading that the differential first leaks and then grenades. I know you are only requesting information when it grenades, but I think issues should be stated immediately! I don't want to be driving down the road with children in the car and have problems then. I contacted Cadillac first and received the heisman stiff arm. I think this is a significant flaw in the Cts dating back to 2004 and should have a recall!.

This letter is pleading to be released from lease agreement and refunded the money invested in my car. I?m no longer happy with the quality of the Cadillac Cts and the number of recalls associated with these vehicles. In essence, I have been leased two new vehicles that were lemons according to lemon laws in the state of virginia. I have had the same safety problem repaired more than three times with both cars. At this point, I am truly nervous to drive my car, more so after reading the many reports of people experiencing car fires, suddenly losing control of their car on the highway, and gears locking up. Most importantly, the car is not safe and I?m scared to continue to subject myself and young children to possible injuries because of the power drain safety problems I?ve experienced before and after the recall. To date, my 2007 Cts has been repaired 4 times for the axle/differential. I?m not an expert but in my findings, the power train deals with differential unit, axle assembly, shaft seal leak, and the automatic transmission. Luckily, these repairs were covered under the warranty. However, the service department is just applying a band aid to the situation. I?m concerned about what might happen next time and who will be responsible for future expenses when the warranty expires. As a result of all this, I would like to be released from the remainder of my lease agreement and refunded the payments made to gmac due to the lemon law. I have never been late on making payments on my cars. As of June 2008, I have paid $14,187. 80 towards my 2007 Cts and look forward to being compensated for a car not mechanically suitable to drive. Your response will be greatly appreciated. Should you need additional information, I can be reached at 301-332-4329. Thanks in advance for time and attention on this matter. Respectfully, lajuan howard.

Cadillac Cts 2007 rear differential broke was driving on the high way and suddenly lost control of the car. The back wheels locked completely. No apparent trigger. Put on brakes (I was scared I was close to the edge of the overpass), shut off the car and the smoke dissipated. No warning at all; no other damage but quite terrifying. Cadillac was extremely responsive and has replaced the rear differential.

Driving approximately 65 mph on i64 in virginia when gears locked up and lost all acceleration. Pulled off to the side and could smell a burning sensation, car then would not move. Back wheels locked up and when car attempted to be moved for a tow, entire back end rattled and grinded. Took vehicle to the dealer as it is still under warranty and has only 15k miles, dealer reported that it was an "exploded rear differential. " all parts were replaced by dealer, who remarked they had replaced many rear differentials in the past yet has never seen one explode like that before. Luckily, driver remained in control of car and pulled over at the very instant there was a problem otherwise this could have resulted in a catastrophic loss while traveling at a high speed on the interstate.

I own a 2007 Cadillac Cts-v. Since purchased the vehicle has been leaking differential fluid from numerous points of rear end assembly. I have taken the vehicle to service 5 times and five times the problem was not corrected. The differential assembly on theses types of Cadillacs are very weak and not able to withstand the power of the vehicle. I think this is deffinetly a safety concern and have done much research and found numerous complaints from other Cts-v owners who have had complete differntial failure where the unit has blown up into several peices which may cause loss of control of vehicle. I think something should be done to correct this problem from the manufacturer. In my case they changed numerous seals and gaskets but after driving vehicle home the leaks always reoccur from the unit flexing because its weak.
