#680 of 721 Is oil consumption still a problem with newer models?
Jul 29, 2013 (3:43 pm)
I love my 2006 CTS but it has gotten to the point where I am running it out of oil all the time. I am thinking of getting another car and would love a newer Cadillac but do not want to go through the same oil headaches. Aside from the oil problem, I love everything else about my car but it is just not worth it. I am wondering if the newer models still have this problem. Any thoughts?

Check out the GMC Acadia forums (engine problems) as the Acadia has the same 3.6 liter engine as the CTS. There have been serious engine problems reported for the Acadia, especially 2007 to 2010 models. It's hard to say whether the more recent models have fewer engine problems. Given the complexity of this engine (e..g. three timing chains), I would not own a CTS unless it's fully covered by a GM warranty. Good luck.

I did a lot of research and found that the oil problem has been reported over every model year on the three point six. One report that might be of interest was a 2013 cts with eighteen thousand miles had oil consumption issues.
I also read that part of this is due to piston rings that are undersized. This individual had the rings replaced at the dealer cost and the engine still seized on them. Others have reported six thousand dollars in repairs from eighteen thousand miles up to eighty thousand. Unless you can afford the cost and don't mind being left stranded-other reviews tesify to computer problems, no starts-and cutting out while in motion-if you can over look these than the cts might work out for you.

Ever since I traded my 2006 CTS I have been looking in car mags-there are always plenty of them for sale..Let me see the car fax. Actualy I've seen all I need to see. The Cts In my review gets a one in a possible five. I rate it only on it's styling. It does look nice, but the performance issues that are easy to research and documented puts this car in the lemon category.
These posts serve only as a buyer beware. If anyone decides to buy a Cadillac CTS and they do not experiance the problems so many do-then they should post as well. but So far the negative comments outways the positive.

I have a 2011 CTS and have not had any of the oil problems discussed thus far (knock on wood). I did have an earlier post where I had some early problems of the whole car shutting off on me 3 times within six months of owning it. After two visits to Cadillac dealership maintenance it seems to have fixed the problem. My guess is that there was a loose connection or short which caused the problem and the full car inspection and checking every cable solved this issue. Thus far....the engine has run well and no extensive oil use problems....again...knocking on wood.

I'm glad I found these series of posts to give me some peace of mind. Regardless of what some of you may think my purchase, but I happened to buy a used 2005 Cadillac CTS 2.8 from a dealership and was surprised to see the engine light turn a week after my purchase. The engine ran great, didn't feel any abnormalities with the exception of the entire car shaking when you would turn on the air conditioner heater. Pretty easy to confirm as you can turn on the AC/Heating and immediately feel the "kicking" sensation. However since I live in cold-ass Canada I didn't really bother with it, even though the car would consume more gas with the heating on than off.
The problem I faced was three months into the purchase when driving from 0 -60 km/hour. After driving for a few months I had a pretty good "feel" as to what was normal acceleration and started feeling irregular gear shifts and "stuttering" coming from the engine. A shriek would sometimes be heard when accelerating/sounding like an awful acceleration noise.
Since my Transmission fluid was at 14% and my engine oil was 20% I figured my transmission oil needed changing. The oil percentage was at 95% when I first bought the vehicle and I thought it was going to be a transmission problem. After taking it to Canadian Tire the mechanic told me that the oil level was dangerously low! And that by replacing the oil the issue with acceleration would dissapear. After the service the engine light also dissapeared and would not come back on again.
I'd like to mention that prior to the service the engine light would either turn off and then turn back on, or would randomly flash occasionally.
With the oil and transmission oil fully replaced I drove for another 4-5months only to find the "stuttering" happening again along with the acceleration grinding issue happenign again now that the car is at 24% oil life (96% transmission). After restarting the engine the "check engine oil" message came on. SO it makes me conclude that the Cadillac CTS takes much more oil than expected and the % indicator for oil should NOT ever be trusted. Thankfully I know what the problem is with the onscreen diagnostics message and the engine light coming on (it's off now), and I will replace the oil in the morning, but it's a shocker to me that the on-screen diagnostics are simply not accurate.
Point taken - check your engine oil regularly and change the oil before it reaches 30%.
As I've only driven for the day to experience this issue, I'm hoping there's no permanent damage. Will keep everyone one posted after the service tomorrow.
