What are some of the 2008 cadillac dts northstar engine problems?

The 2008 Cadillac DTS is a pretty reliable vehicle with many positive reviews. However, that doesn't mean that it's without its issues. Drivers report seeing things like oil leaks, failed speed sensors, and leaky transmission cooler lines, but these shouldn't deter You. If You're looking to the engine in particular, there are some things You should stay on top of. Oil leaks are the single most reported issue; therefore, it's important to stay vigilant of Your DTS's oil level at all times. If You see a leak, be sure to have it repaired as soon as possible. The ignition coil is also known to fail from time to time; luckily, it's a relatively simple swap that shouldn't take too big a bite out of Your wallet.
