The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern.

Cadillac SRX Rear Axle Pinion Seal May Leak
Cadillac SRX Problem
Average Mileage: 61,000 mi (36,000 mi - 74,000 mi)
rear differential axle leak.
Was told by the dealer to watch it, which I did.
I also asked dealer (at each oil change) if it should be repaired. Was told not yet. I trusted my dealer.
Now that the 5 yr warranty is over, they say I should fix it.
Seems very unfair to me.
Oil leak at differential. Took Caddy dealer three attempts to fix. They had to replace entire rear end housing.
