“This northstar engine has leaked oil,(not burning it) since 40,000 miles. I use 2 or more quarts of oil between oil changes. It leaks whenever it is parked. I have spent monies on this, but it appears a major engine repair is needed. Some say, the bolts were too short, and others say, this defect continued until the 2006 year.”

NHTSA complaint #10641495, filed 2014-10, 7,000 miles“Engine began to leak oil after 40000 miles. The company and dealership assured me this was normal.

The leaks continue to this date. Engine stopped once on me, shut off, nothing worked. No airbag, any electrical service. Hit hole in road and everything shut off. Called company many times, wrote to president, other executives all to no avail. …”
NHTSA complaint #10641497, filed 2014-10, 40,000 miles“Vehicle cuts off at random times while in motion. The car ignition cuts off all power to the engine and power steering when the car hits a bump, railroad track, or pothole. Bumping the column cover will also cut off the engine, and the power steering. The vehicle has had the key modification which would appear to have no affect on the problem of the ignition randomly rotating out of the on position.”
