Hello! My wife and I recently took our 2013 Chevy Malibu (2.5L engine; 85,000 miles) to a mechanic we trust(ed) to have the camshaft position sensors replaced since the error code for the camshaft was coming up and the car was presenting with all of the general symptoms of a camshaft sensor issue. The mechanic replaced the parts, but the error codes are still coming up. They suggested that it could be an electrical issue. The real concern, however, is that within 6 hours of leaving the mechanic we have started experiencing issues with the engine (supposedly) overheating. The temperature gauge will rise rapidly if the engine goes over about 2.5k rpm and we will get an error message saying that the engine is overheating, it will shut off the A/C (or say it is shutting off the air, since we have started driving it without the A/C on), and instruct that the engine should be idled. Sometimes when it says it is shutting off the A/C, the gauge will drop all the way to the bottom. After about 5 minutes with the engine off, the car will start normally and not have any temperature issues for 5-10 minutes. There have also been a few occasions that the engine will keep running after the ignition is off. This usually happens when the car has had an issue with the engine temperature, but there is not a one to one correlation.

My question is, is there anything that the mechanic might likely have done to accidentally cause these issues when replacing either of the camshaft sensors? I can't find an engine diagram that has the location of both the camshaft and temperature sensors, but from what I can find, it does seem that they are relatively close, all things considered. I would like to know if these knew issues are likely due to some negligence on the mechanic's part, or if this is just the worst of coincidences. Any other thoughts on issues that might cause these problems and at least short term fixes would be greatly appreciated. Thank you!

I am also having the same problem at just about the same milage on mine. This is only one of the long list of problems I am having. The most recent being the transmission going out and the extended warranty company would only replace it with a junkyard transmission and now I'm having additional problems but now the warranty is 8 days expired so they won't do anything to help. I even called GM to see if they could assist me. I am disabled and can't afford to pay for any additional repairs but GM said that they can't help or get involved.
