On a cold 12 degree day on 1/19/2020 I was driving my 2013 GMC Terrain on a busy state highway doing the speed limit of 55 mph. Out of no where I began to smell the odor of burning oil and seen white smoke coming from the rear of my vehicle. As soon as I noticed it my car's gauges started coming on. The check engine light, a warning to for "service stabilitrak", then the warning for "engine power reduced". at the moment my car all the sudden shut off while driving down a major highway! there was no power steering and it was very hard for me steer my car into the parking lot of walmart and safely off the road. Once in the parking lot I got out of the car and checked my oil. Smoke is rolling out of the dipstick shaft. I check my oil weekly due to GM's oil consumption issues with the 2013 GMC Terrains and on 1/15/2020 the oil was at full, was of normal color and consistency when I fueled and checked it that day. So I was shocked to see that there was no oil on my dipstick and instead a milky brownish sludge on it. I sent my fiance to buy me 2 quarts of oil just to get it to the walmart service department so they could look at it since I was in the walmart parking lot. I added the oil drove it 100 yards to the service dept of walmart. The service man pulled it into the garage and then informed me a few minutes later that the rear main seal blew and oil was flowing out of it. It was not driveable so I had to have it towed to a GM dealer. The GM dealer called me this morning 1/21/2020 to inform me that the rear main seal blew due to moisture in the intake and a froze the PCV module and caused to much pressure to build up and blew the seal. The dealer quoted the repairs to be $2065.69 and informed me that the repairs are not covered under the GM service bulletin #14882 because my VIN number is not included in the service bulletin.

Showed stability track. I was driving on the highway when it showed service stability trak then engine power reduced. It took my speed from a 65 to 35 in an instant causing me to almost crash. Then the car started to jerk as I tried to drive to find somewhere safe.

My car since day one steering wheels locks up constantly, the brakes do not stop you the worst is the engines battery which is located under the seat constantly says I have no power it will turn on several codes and the start idling the rpms go up like your press G the gas but you not then you stall you can be going 70 or 20 mph and it will just stall with no warning. The steering wheel will and I lose traction in regular roads in perfect weather. I can't seem to locate my airbags I have had my vehicle services a million times they always say nothing is wrong also when the rpms or going up.and down I lose all headlights and dash lights. This has happened to me at night so many times. This vehicle has almost killed me so many times I lost count I take it to service there is never an issue. I'm probably going to end up in a severe accident soon the brake pedal sticks and I can't press it down I had to pull into grass one time to avoid a car.

This is the second time in a year that the service stabilititrak light has come on and a message to do that has come up on the information screen on the dash. When this happens the engine power is immediately reduced. Then you cannot turn this off as it locks the controls for this feature which can normally be turned on and off. I took the car in the first time and there we're relay and sensor issues which they fixed. I am waiting for the call as to what is going on this time. Is this a safety issue for not just this vehicle but any vehicle to have a feature that you can turn on and off to immediately cause power loss" should you not be able to turn this feature off to avoid causing an accident and possibly causing someone to be injured or killed" especially since this is a feature you can turn on and off anytime you want when it is working correctly. I have read on different web sites that others have had this same issue.
