Tank Assembly Problems of GMC Acadia

2014 GMC Acadia denali. Consumer writes in regards to inaccurate fuel gauge reading. The consumer stated on April 28, 2014, the fuel gauge was at 1/4 full. After driving 30 miles, the low range warning displayed and the gauge needle was at empty. The consumer stated 30 miles could not have used 1/4 of fuel. When he went to fill the tank, the fuel gauge was back up to 1/4 full.

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.

Several issues with this new 2007 GMC Acadia. Most prevalent is the failure of the gas gauge not reading the gas reading correctly. 1st time noticed and taken for service was 3 mo. Old. The gas gauge reads (e) when I've just filled up the tank. Dealer replaced 02 sensors. 1 mo later experience same issue. Gas gauge reads (e) even when tank is full. Taken back to dealer and this time replace (2) O2 sensors and the "sending unit". 2 days later, with the gas gauge reading at half full, the car lunges forward into another gear on freeway in traffic, and stalls. Cannot turn car on - all warning lights on. Towed to dealer. Now states that I need a whole new gas tank because the "baffle" is broken? still at the dealer and is unresolved. This car is unsafe. Previous issues: car leaks at the sunroof. Not fixed yet lumbar support broken - somewhat fixed but still not like the new ones on the lot. Lumbar handle fell off - replaced backup sensors fell off of bumper - replaced seat tracks jerk - replaced both driver and pass. Still not smooth but dealer says that's the best they can do.
