Electrical system complaints dominate owner reports for the 2010 Cadillac DTS. The most frequently described issue involves the vehicle shutting off unexpectedly while driving, sometimes at highway speeds, with owners reporting loss of power steering as a result. Several reports point to a fuel pump relay and rear fuse box failure as the mechanism behind these stalls. Owners also describe an airbag warning light illuminating and remaining on without an apparent triggering event. Engine oil leaks are the next most common complaint, with multiple owners reporting oil seeping from the oil pan area, in some cases losing roughly a quart every short stretch of driving, with the oil pan gasket cited as the likely source. A smaller cluster of complaints involves the seats, though those reports are less detailed in describing specific failure modes.

By System
The 2010 Cadillac DTS has two recalls, the more serious being an electrical cable that rubs against the power steering return line, which can wear through the line and cause a fluid leak that leads to sudden loss of power steering or an engine compartment fire.
The second recall is a compliance issue: the tire and loading information label was not installed on the vehicle. Without this label, owners may not have the correct tire inflation and load capacity figures on hand, which can lead to overloaded or underinflated tires and reduced handling.
