Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have read numerous complaints for the same issue I am reporting on the internet on various websites. The dealership mechanics can't determine the issues and something has to be done! The first time I experienced the problem I was slowly (less than 5mph) turning the steering wheel in the right direction into a parking space and the vehicle would not stop, it jumped the sidewalk, but stopped before hitting the building. …”
NHTSA complaint #10567575, filed 2014-03, 80,000 miles“My 2006 Cadillac CTS with a 3.6l v6 started burning oil excessively at about 25,000 miles. It now has about 31,000 miles and burns a quart every 800 miles. I drive about 6500 miles per year, mostly in short distance city driving. The car still drives well and it still passes the texas vehicle inspection which includes emissions testing. The oil gets black quickly after a change. This oil consumption is excessive for such a low mileage car.”
NHTSA complaint #10330037, filed 2010-05, 31,000 miles“My 06 Cadillac CTS had less than 35000 miles on it and less than 3,000 on an oil change when I noticed the oil level was below the reading marks on the dipstick. No drips on the ground. After researching I discovered their spec is to burn 1 quart per 1000 miles (1 quart per 500 miles if aggressively driven). I took the car in for an evaluation to see if it hit their specs , and the service manager performed an oil change, and set me up for a reinspection at 2,000 miles. …”
NHTSA complaint #10323727, filed 2010-04, 30,000 miles“I took my 2006 Cadillac CTS into a GM dealer for a recall. They also changed the oil. Ever since they changed the oil, my car has been burning an excessive amount of oil. I had to put a quart of oil or more about every 500 miles. I put in 1 1/2 quarts on a wednesday and on a monday my car began making a loud knocking sound in the engine. Gm will not listen to me and now my car probably needs a new motor. I have babied the car and this is not my fault. Oil is in the car at all times and it should not throw a rod with oil.”
NHTSA complaint #10408877, filed 2011-06, 77,700 miles“Timing chain broke while cruising on highway, 70mph. Incident caused catastrophic engine failure requiring entire engine replacement, $8500.00. Odometer 66,998. 2006 Cadillac CTS, 3.6l v6 engine, rwd.”
