2012 Chevrolet Impala: fuel pump failure

Filed Jan 27, 2024 · Body, Electrical · GA

The actuators in the air vents are faulty and I've had to have them repla ed multiple times now. They still continue to make clicking noise sounds and blow cold air in winter/hot air in summer. The trunk deck lid paint is bad. The clear coat has been coming off. Paint all over the car's clear coat has been coming off. There is also some spots where it's down to the metal showing rust/corrosion. Finally, and most seriously, is the car's Traction Control System. It goes off constantly and without warning! It's been doing this randomly, in all types of weather conditions, for some time now. It goes off under normal driving conditions. I barely pull out of a parking space, or make a slow turn, or pull out of a parking lot at a very slow speed and it just goes off. The really dangerous part is that it stalls the car almost to a complete stop, when I've been making a turn well before oncoming traffic, and it stalls almost causing an accident on several occasions now. Most of the incidents are on sunny days where there's no inclement weather! This system is not safe and is unreliable. I've checked many public forums, like Reddit, and there are many other Chevy Impala owners who complain of the same exact problem. Yet Chevy has issued No recalls!? The only recall I've seen close to this is for 2011 year models. Although my car is a 2012, 2011 parts likely were used. If the recall affects 2011 Impalas, then any model that used 2011 parts should be included in this recall. I cannot trust the safety of my car's Traction Control System anymore as it comes on without warning, under no circumstances where it would need to come on. People are in danger with this defect! The car cosmetically, specifically the paint job and the flimsy actuators, are also defective. I've always taken excellent care of my vehicle, regularly having maintenance done at my local Chevy Dealership. Another defect that Chevy had to fix was my fuel pump that went out for no reason! I have receipt for this.

I have a 2012 impala that I have had since 2015 and a little while after I got it the engine light came on and it said it was the fuel pump control module requested Mil illumination and evaporated emissions systems leak detected (large leak) and at times the gas tank sparys back at up if you don't let it sit open for a little bit. I have had these issues fixed multiple times and by multiple mechanics who still can't figure out what's going on.

While driving on the highway the check engine light & traction light came on at the same time as these 3 messages, engine may loose power, severice traction control, stabilitrack. The engine started slowing down & had a high pitched whinny noise. After about 10 miles the message changed to engine iis loosing power, wouldn't go over 35 MPH and the whinning became louder and faster. I had to have it towed to a gm dealership, where they diagnosed it as the high pressure fuel pump. I was told the parts are on back order until may 15, 2018.

I was driving to work. My car started to lose speed. Until it came to a complete stop. I called for a tow truck, that towed my vehicle to a repair shop. After diagnosis of my car the repair guy, informed me it was my module fuel pump flow control. I wanted to know more so I google the problem. I came across a recall on gm site, bulletin 14515b. I noticed it was a recall for exactly the same issue I was having. So I called chevrolet to see what steps I needed to take on getting reimbursed for an issue that clearly has been a problem on several 2012 impala's. I was told,it was a recall but not on my 2012 because my VIN # begin with a w. I explain to her that didn't make sense to me. All 2012 was in production at the same time. I'm pretty sure they used the same part on the vehicle. I was told it was nothing she could do. I informed her I will be filing a complaint.

Car has 68,000 miles. A few days ago the engine light came on, which disabled remote start. I didn't realize this until I went to get into the car. I'm in mi and this past week has been very cold. I jumped in and drove it to work (less than 3 miles). On the way, the traction light came on. No surprise, as it was a little slippery. No other problems. On way home from work: car starts up fine, no warning lights at all at start. Its about 13* out. Almost home: engine light comes on, traction light comes on, then right before turning on my road the stabilizer light comes on and reduce power light, car jerks and loses power like its going to stall out. It made it home. Next morning, engine light on but nothing else happens. I call around and dealership suggests I bring it in and hook it up to run a diagnostics for $98. I go over to parts store and have them run it first. Error codes show up that "don't really mean anything" and they reset the engine light. Runs a couple of days fine with no problems, lights coming on etc. Temp drops again and repeat the whole process all over. I bring to the dealership and they tell me it needs high pressure fuel pump and new lines, after they asked me if I ran e85 in it, which I do because that is what they suggested when I bought it! I can't afford the $900 right now and I picked it up. I called another dealership to get another estimate and I'm told that this is a common problem (we're seeing this all the time. It's a problem with running e85 in cold temps). That person suggests I run mao44 and prem unleaded in it and it should run fine for a while. I"m also told that this is not covered by the powertrain warranty and there has been no recall, even though "we're seeing this all the time".

The vehicle has a loud knocking sound from the high pressure fuel pump when you take off from a stop.

2012 chevrolet impala lt. Consumer states high pressure fuel pump is very noisy when accelerating from a stand still and also states issues with vibration *tgw the consumer stated the accelerator motor made a loud noise. The consumer stated the fuel lines, which apparently run directly under the driver's side floor, vibrate due to the harmonics set up by the high pressure fuel pump. The vibration is continuous and can be felt through the floor and up into the driver's seat.
