I was changing the oil and noticed some oil leak on the oil pan area next to the oil plug. I wiped the oil off and noticed three cracks in the casting which I believed to be a manufacturing defect in the casting. I am still under warranty and took the SRX to the Cadillac dealer and showed the service writer the picture. He had never seen this type of issue before. The SRX was sent to the service mechanic and he saw the crack and apparently according to the procedure before changing the pan out, that he would have to determine if a leak was occurring. Since I wiped the oil off, the mechanic had to take the car home to drive it and put some miles (40mile) on it to see if it would leak. A dye was put in the oil to help determine if a leak would occur. After the 40 mile drive no leak was yet seen. It probably takes way more than 40 miles to have the leak seep through the casting.
The mechanic looked at some other SRX's and supposely saw similar cracks in the casting. He believes this may be normal to crack like this. I have the SRX back and will drive it for awhile and see if it starts leaking again (I'm sure it will).
Has anyone seen this type of cracks on the casting on 2010 SRX's or other similar situations. Could this be a manufacturing defect in the quality of metal used in the casting? If so, there are probably many other SRX's out there waiting to have the same problem. If not changed out before the warranty expires I suppose it will be an expensive job.
Any ideas or similar incidents please let me know.
Hopefully the picture attaches to this file correctly.
Automobile(s): None at the moment. Maybe some day an SRX!
Re: Oil Pan Casting Crack
Therealplumpshady, I'm so sorry to see this has been frustrating you! If you do see the leak occurring and decide to go back to the dealer for service, please let me know. I'm available via email at Katie_Lucille@gmexpert.com, and I can contact your dealer at any point to follow up on your behalf.
Thank you for the offer. I will let you know what occurs.
Thanks, I hope you don't have the same issue.
When I bought the car the dealer changed the oil prior to me taking possession. Taking the plug out seemed to be the proper amount of torque to take off the bolt, nothing difficult. I can't imagine the GM mechanic would use a torque wrench to reinstall the plug. The thing that is interesting is that I was told the mechanic checked other SRX's and saw the same cracks....would lead me to believe the casting quality maybe at fault. After a few years of use then the cracks show up.
