While driving the vehicle at 45mph I received a low oil pressure shut off engine. Oil was fine so we took it to have the oil changed. Light came back on. There are no codes being stored in the system. Everyone is guessing what could be wrong with it from a bad oil pump or the pan needs to be cleaned. There is a forum a bunch of other people having the same problem and spending thousands and getting nowhere. Some have had to have a whole new engine installed. Gm says there are no bulletins and they will give me a 100 $ for the vehicle to be serviced by a tech. Just to be checked is 250 $ not including any fixes for the issue.

Bought the car on feb. 28, 2018. Found out on january 23, 2019 that it needs a new engine. This is now the 2nd gmc acadia we bought in less than two years that needs a new engine. That is not right. We have now spent over $20k for two cars we currently don't have a working car. The last car I bought was a 2010 gmc and I was driving the car on the highway and smoke started coming out of the engine. Later it was determined that the engined died - there was never ever warning lights or warning that there was trouble with the car. Both cars have the 3.6l sidi vg engine. Our auto place said they are having a hard time finding that engine because many people need that engine for the exact same problem. Can not be a coincidence. I have contacted gmc and they don't care.

Current issue is a transmission failure, apparently the "3-5-r waveplate." five months prior, my wife and children were traveling out of state. They experienced a sudden loss of power and were stranded on a rural highway not once, but twice. The vehicle was towed in to a gm dealership, "repairs" were performed under warranty, and we were told we could pick up our car. My wife (again with children in the car) made it less than 10 miles from the dealership before the engine failed again. This time on the bridge of a major highway....no where to even exit the vehicle. After the second incident the engine was replaced (after 3+ weeks of diagnostic work). We were told the dealership was not able to identify the problem that caused the engine failure. Engine was replaced under warranty. Transmission had been shifting erratically for several months. At time of engine failure/replacement, gm dealership that performed the engine replacement advised us that the transmission shifts/slips were "normal" for this particular transmission. They advised a transmission fluid flush, which we authorized. Shifting remained abrupt, slipping continued, but as we were advised this was "normal", we continued driving the vehicle and did not seek further repair. Two weeks ago, (now six weeks out of warranty), the slippage became distinctly more evident, vehicle at one point wound not continue forward motion through an intersection and had to be idled to roadside. After multiple calls, we were advised to take the vehicle to a local gm dealership. Diagnosis of 3-5-r waveplate failure was given. This transmission waveplate failure is a well documented issue that can cause driver and/or passengers to be put at serious risk for injury. Our hope is that an investigation will take place to require gm to recall/repair this issue before someone is needlessly harmed.
