Differential Unit problems of the 2004 Cadillac SRX

Hood hydraulics bar doesn't stay up on front. Rear hydraulics hatch door doesn't stay up. Brake line is rotted yet was garaged for most of its life. Caddy repair noticed this. Front and rear differentials are bad. They are leaking. Brought it in because of the noise to mechanic and too costly to repair. Extended warranty was useless. They didn't cover it although it states they cover differentials if. . . Loud noise on acceleration. Very costly repairs and dangerous.

I was sitting at a stop light, in my car, with my mother in the passenger seat. When the light turned green I applied pressure to the accelerator and the back end of the car made a loud enough thump - I thought the axle broke off. As I continued to drive away from the intersection I looked in the rear view mirror for remains - there were none. My mother commented on the noise, I did not know what to tell her. She also has a cadi Srx, 2005. When she returned home she noticed the same noise in her cadi. Her husband said it was the "rear differential. " since that time their cadi was lost in a flood and they purchased another cadi Srx, 2008. This cadi also has the thumping in the rear differential. The thumping continues when accelerating from a stopped position. I have come to the conclusion all the Cadillac's have rear differential issues and there needs to be some kind of action against this issue. This needs to be addressed. My next step is to go to the better business bureau.

My 2004 Cadillac Srx also has the leaking pinion seal described in the following recall. . . . . It has leaked since I have owned the car but now is grinding. Should it not also be covered by gm? 2005 Cadillac Srx power train recall 07v589000 NHTSA: action number: n/a service bulletin number: 07v589000 ?report date: Dec 20, 2007 ?component: power train ?potential units affected: 275936 ?manufacturer: general motors corp. Summary: on certain passenger vehicles, the rear axle pinion seal does not meet all of the specifications and may experience a fluid leak. Consequence: a rear differential failure may cause loss of motive power and possibly loss of control increasing the risk of a crash.

At about 65-70k miles the rear differential started making noise in my 2004 Cadillac Srx. I took it to the major Cadillac in kansas city, they told me it was normal. The whine turned into a mechanical clucking sound when the car accelerating from a stop. I returned to the same dealership. They told me it was a common software updated that need to be installed (and charged me about $250). When I picked it up, pulling out of the parking lot, the noise was still there. I asked for a refund or for them to actually fix the issue. I was told to return when my service rep was in. The next day the dealer was shut down by gm. I understand some of these details don't directly to the issue (which I will further explain), but seems to be a symptom of how the gm dealers handle issues. Today I took it to one of two remaining gm shops in town. They needed to perform a $200 fluid exchange on the rear differential to determine whether it was the issue. Then called me back, saying there was no 100k mile warranty on the car and the replacement would be about $1300, along with the additional items that "should be done" putting the total to over $2500. On a car that now has just over 70k miles and is not quite five years old. Had I not seen so many other owners with the exact same issues with the model, I would have thought it was a rare occurrence. But given the bevy of individuals with the same thing happening, this would seem to be a glaring design defect. I appreciate there is a place to compile these complaints. Maybe action can be taken to remedy this issue. Thank you.

The contact owns a 2004 Cadillac Srx. While driving approximately 50 mph on normal road conditions, the contact heard a loud noise outside the vehicle. The wheels locked up and failed to operate. The driver felt that this was a life-threatening situation because the vehicle just stopped without any warning. Roadside assistance was called to the scene and the vehicle was towed to her residence. An independent mechanic inspected the vehicle and stated that the front end differential failed. The vehicle is in the process of being towed to an authorized dealer for repair. The failure and current mileages were 80,000.
