On 9 Apr 2016 on the way to a church function, our 2010 Acadia told us it was reducing engine power and started missing and smoking a little. Thankfully we were just blocks from the house, so we turned around and limped it home. Later I moved it from the driveway to the street. This time, while still missing, the vehicle put out a dense fog of white smoke that smelled of gasoline. Thankfully no one lite a match. I used my obd II code reader to get failure codes P0087 and P0089 indicating low fuel rail pressure and injector issues. Subsequent research on-line led me to tsb pip4924D (NHTSA# 100419330). I now am of the opinion that the issue is likely a fuel injector that is stuck open likely due to a fuel injector control line that is shorting to ground due to bad manufacturer design or improper maintenance by dealers fixing other issues. I view this issue as a huge safety problem. I can think of all sorts of scenarios where this could cause danger to the vehicle driver and passengers. A little about me... I've been working on cars for the last 48 years and hold a bs in electrical engineering. Anyone is welcome to contact me at [xxx]. (unrelated... I was also disappointed to learn from one dealer when fixing an A/C issue that my brake booster drum was contaminated with brake fluid due to a bad seal I guess. That fix was costly and likely should have been on the manufacturer also). Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Letter from congressman rigell on behalf of constituent re recall general motor vehicle. The consumer stated a year after the he purchased the vehicle, the engine light illuminated. He took the vehicle to the dealer to have it serviced. A few months later, the light illuminated again. The dealer informed him, the fuel system needed to be cleaned. After the oil was changed, the tire light illuminated, the ac stopped working, the windows were inoperative and the hood and trunk would not stay up or down.

For the last few weeks, the fuel light in my wife's 2010 Acadia will not go off. We took it to the dealership. They told us there was too much alcohol in the fuel, @ 12%, and if it reached 15%, they would need to drop the fuel tank. They said to run a couple of tanks of 93 octane through the vehicle and it should correct itself. After 8 tanks of 93 octane at $3/gallon, the light it still on. Gas stations do not readily advertise or display the % of alcohol in their fuel, much less if alcohol is even in the fuel. It seems a bit disingenuous on the part of GM to have this problem with the Acadia, knowing how alcohol is used in fuel these days. We paid a lot of money for this vehicle, but can't afford to run 93 octane through it the rest of the time we own it. I've been a big supporter of GM, but this is very frustrating and incredibly disappointing.
