2006 Pontiac G6: won't start

Filed Oct 18, 2024 · Electrical, Lights · OH

I have had to get 3 new keys made for this car due to the security light coming on, sometimes it will not crank or start, so I have replaced the starter twice, have replaced relays and fuses, and the security light will come on while drive down the road and all gauges drop to zero, even the gas light says empty and every light on the dash comes on. But the car will still drive. But once you turn it off it will not start for a few hours! It’s impossible to find parts for Pontiac anymore so everything has to be ordered! This should’ve been recalled a long time ago!

This is a 2006 pontiac g6 with the 3.5l lx9 v6 engine. At 90,000 miles I am having transmission problems (automatic). The transmission slips in 2nd and 3rd gear. The car reverses normally. All maintenance is done by myself or the dealer. I changed the transmission fluid with genuine gm parts and fluid. I noticed the fluid was slightly discolored and very tiny pieces of metal were in the pan. The transmission still slipped in 2nd and 3rd gear after changing the fluid. Obviously I want to avoid putting in a brand new transmission. I want to check the computer and and any electrical pieces that correspond with the transmission first before I decide. As a side note,I did bring the vehicle to gm for a diagnosis and apparently there was a code for a transmission position sensor. However I attempted to start the vehicle in drive on many occasions and the vehicle would not start which is what that sensor is suppose to do so I know it isn't the sensor.

At approx 70,000 miles notice fuel odor around gas tank. At approx 70,300 miles the car would not crank until second attempt and the fuel smell is much more pronounced. When vehicle sits for more than an hour, it takes at least two attempts to start.

I have a 06 g6 2.4l 4cyl and lately it has been giving off a strong fuel smell. I smell it when the car is stationary as well as when the car is in motion. I checked for leaks under the hood and car and cannot find any. When I attempt to crank the car it doesn't start until my second attempt. I had a mechanic look at my car and he could not figure out what the issue was. I am becoming more and more worried with this issue. I have a small child and his car seat is located in the passenger rear. I am very concerned for his safety as well as mine. I am afraid that one day my car may burst into flames while we're on the highway, at a red light, at the mall, etc. Putting not only our lives at risk, but also the lives of others nearby. So I took the car to auto zone and they hooked it up to their scanner for free. They gave me this code - p0454 fuel tank pressure (ftp) sensor intermittent.

While driving there was a noise similar to that of which you hear when the seat belt isn't engaged then the display on the radio reads "engine power reduced" then immediately after that it reads "engine power disabled" and then the car shuts itself down. I was able to coast to safety where I then turned the ignition to off. Tried to start it again but the car was completely dead. I waited 10 minutes and then was able to start the car again but it didn't start normal it kind of sputtered and then started. I was then able to drive home. A second occurrence happened a different day when I was parked. I started the car and it immediately made the above mentioned noise, gave me the same 2 messages and then shut itself down. I then could start it again after about 10 minutes. I was told this was a throttle body issue by a dealer and have not yet had this problem resolved. This is a very dangerous thing to happen while you are driving especially if you have small children in the car. This should be a recall immediately.

I live in south florida, owner of a 2006 pontiac g6, I noticed a fuel smell from the inside of the car, and rear wheel-well, also would not start on first attempt, starts on second attempt . Looked online found a recall on 2007 pontiac g5 regarding this issue, the federal safety agency campaign number: 09v41900, in hot weather states with other gm vehicles , obviously this is a common problem and a recall should address it, it is a very dangerous situation. I did some research and seen numerous post and a high failure rate of a plastic fitting on the fuel pump. This needs to be addressed to gm as a possible fire hazard and a recall in place to save lives!!

I have a pontiac g6 2006, I was driving at or around 25 MPH and the car suddenly shut off, when I came to a stop I tried to restart it but it would not start. Before it shut off I heard some sort of screeching sound. Upon taking it to the dealership I was told I would need a new engine. I bought it preowned with 63,000 miles. I find it hard to believe that the engine would die after 73,000 miles.

Several times when attempting to start the vehicle by turning the key in the ignition the vehicle goes through the process but doesn't start. It will make a "winding" noise. It will take 2-3 attempts to get the vehicle started. This has occurred approximately 30-40 times since 2009. During this same period while driving the beep alarm inside the car begins going off cause it reads that someone is sitting in the passenger front seat without a seat belt. Each time this has happened the seat was empty. In addition, when a person has been sitting in the front passenger seat and vacates the seat the seat or sensor still registers a person there without a seat belt. During the same time period I have had to replace the headlights and front driver side about 6-8 times. I had the front driver side maker light replaced and it was noticed that it was completely corroded. I've had to replace the back brake lights 6-8 times. Lastly, the transmission has begun stalling both at initial acceleration and when driving above 35mph the vehicles suddenly loses its gear and begins to slow down in traffic. This vehicle has major electrical problems. To add, I have spoke to 4-5 other people that have the exact same and additional problems with either the same year, make, and model or the same problems with the same vehicle just a year different.
