Issue all began exactly one year ago. One day I tried to crank my Yukon and nothing. Dealer replaced fuel pump. Then a month later same issue, replaced it again, then several months again. Then my Yukon started stalling, jerking while driving on busy highways, very dangerous by the way!! Had to pull over to try to restart engine. I was stranded on the side of the road multiple times.
My roadside service suggested that I find a new dealership that could fix problem. I assured them that it was not my dealership's fault. It's the faulty replacement parts although genuine GM parts. Not sure where manufactured? Then one night it stalled again. Engine dies every time after it stalls and jerks. On the road in the dark. Tow truck takes the vehicle to my home and then comes back again in the AM to take it to dealership again.
Everyone thought it was an electrical issue because several months ago when it wouldn't crank & then it was unloaded from flat bed tow truck, it would crank for the mechanic after being unloaded from tow truck. The mechanic even kept it a week and drove it to & from work for a The funny thing is every single time the vehicle has been taken to the dealership, it cranks for them except the very first time when they replaced the fuel pump. NO CODES EITHER! They even joke about having me clock in when i'm there because I'm there every other week it seems. I know they probably think I'm imagining all of these issues. No, they are really concerned with my safety.
Then the next time the Yukon broke down, the dealership replaced the catalytic converter because it bogged down and would not run but a few feet at a time and finally died. Sediment in exhaust I suppose? A couple of months later it did it again and the dealership replaced the catalytic converter again. Well over the last several months it was still stalling and engine dying when I slow down to turn onto a road or driveway. Now taking longer to crank and rough engine idle. And here it is exactly one year later.
I have it at the dealership once again on a Friday, a day before I drive on vacation because it is acting up again. At least there were codes this time. The codes were for Transmission range sensor and trans. range switch. I looked back at my invoices from past year and several sensors had been replaced, throttle body cleaned, TBPS changed, almost every sensor and module, all filters air and fuel were replaced. I joked to service advisor that it will probably break down while on vacation.....Yes you guessed it! It started stalling around 300 miles down the road. Pulled over due to engine failure 3 times. It restarted all 3 times but, the 4th time it would not even re-start. In the middle of a tropical storm.
Got the towing service to take it to GM Chev. Cadillac dealership only 5 miles away... God was looking after us once more....on a Holiday weekend. Left it there. Went to airport to rent a car only a few miles away thank God again... The dealership called me on Memorial Day to tell me the problem was the CRANKSHAFT POSITIONING SENSOR and they actually had part in stock. Repaired it on a holiday and the next day my husband and I drove 2 hrs. back to pick it up and 2 hrs. back to our vacation location. It has been running fine ever since. Even better gas mileage.
They told me at the dealership that if the crankshaft positioning sensor was going bad it would make the engine run rough & stall because it monitors the crankshaft, this information is used by the system that manages the engine systems that control the fuel injection, ignition system timing, etc. Makes since to me. Wow so maybe everyone that is having engine stalling problems could have the crankshaft positioning sensor changed. It was approx. $295. total to repair. A lot less than all of the other thousands of dollars that I have spent in the past 12 months.
I know it is not suggested to change parts at random, but, it looks like a lot of people are having this problem. And this was exactly the part that my vehicle needed to solve the issue. When the CSPS isn't working properly it can make other components not work properly and make them throw a code. It actually had a code stored this time. Maybe it needed to be driven a very long distance and get very heated to actually throw a code? Thanks for letting me vent because no one else wants to hear about it especially my husband hahaha.....it was getting old after an entire year......
