This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
I have trouble codes that occasionally come up even after vehicle has been serviced. The vehicle used to drive fine. Now it started miss firing. I was told the problem was coming from the engine compartment/sensors. An OBDII diagnosis detects a problem with B Camshaft Position Timing Over Advanced or System Performance Bank 2 (p0024). I fear that without the fix, the miss firing can cause an accident. The engine light is illuminated when this happens.
Fuel pump replacement with Gm dealership parts provider now car engine doesn't shut off right after key is turned off and car doesn't want to talk gas when fueling then doesn't want to start after fueling
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.
2/16/2019 (sat 3:30pm) : suddenly lost power when driving at 70 mph on highway 99 near fresno, California. Felt like no gas coming in. Engine was still on, but gas pedal seemed to pump no gas to the engine. Pumping the gas pedal had no acceleration response. Speed continued to drop on the highway, very dangerous! finally, luckily pulled over to the shoulder without mishap. Engine was still on when stopping by the side of the highway, kind of idling at low RPM. Shut off the engine and tried to restart it to hope for the problem to go away. Cranked a dozen times and could not to get engine to continue. Felt like running out of gas. 2/17/2019 sun: The car was finally towed to a nearby dealer. 2/18/2019 mon dealer service diagnosis reported broken "fuel flow control module". the estimate of its repair (part + labor) is near $500 I have asked the replaced module to be saved for investigation. Summary: Sudden failure of the fuel flow control module that completely cuts off the fuel without a fail-safe design, nor a warning, for a part not in the regular maintenance list, particularly at low mileage (42,000) exposes drivers to high risk of accidents on the highway. Action requested: It may be a quality-escaped issue on such a module. Failsafe design is needed for 21 century highway safety. I ask NHTSA to request GM to investigate this case to determine the cause of such sudden failure of fuel flow control module on a low-mileage car.
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.
When using E85 fuel in my flex fuel vehicle the check stability control/reduced engine power warning is activated. This occurs when the car is moving. I have contacted my dealer and GM they were unable to help me. There is a GM technical bulletin (pip5385C) on this problem.
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 engine goes dead without warning while I'm driving down the road. No lights on or any other indications that it is about to happen. Will not re crank. Realize that it happens when my fuel system is about 60 miles to empty. After putting gas in I can crank it right up and go until it hits around 60 miles to empty and it will go dead again without warning, very dangerous and scary thing to happen in traffic. Dealership technician is stumped as to what it is, they have changed one part and it did not work, engine went dead on him also when he tested drove it, car has been there for almost 2 weeks now and they don't know what to do. I need my car back.
Driving 55 mph on the interstate noticed that I hadn't filled up in a while yet the fuel gauge still read "completely full". filled up at gas station took 3/4 of a tank. Gauge has been alternating between full and completely empty for a month. Could have run out of gas at speed on interstate causing accident internet research has uncovered a few incidents like that. Chevy support is willing to waive the 50 dollar diagnostic fee but will not cover repairs. Local garage quoted 250 labor 160 part to replace fuel gauge sensor in the tank, but from online research past years have seen instrument cluster failures in fuel gauge, speedometer and engine temp. Car has 50800 miles on it is four years old and may require repairs 400-2K depending on which part is failure. Previous GM products have had class action lawsuits for similar issues. This is a safety issue as the gauge fails and the check engine light took 25 days to come on with the error code in the 460's that the sensor was bad. Currently driving vehicle with broken fuel gauge and submitting complaints talking with support to try to get them to cover repairs.

Car cut offs when put into drive car cuts off while driving. RPM odometer stops working. Check engine light comes on reduce engine power. Stability track and ABS stop car from turning. GM dealer said its battery terminal wires and a new battery changed both and same issue. Fuel pressure sensor keeps going bad replaced twice. Car is choking on to much fuel rotten eggs smell coming from exhaust. Car is very dangerous to drive has cut off on me in traffic to many times now. Once and if problems are ever found their needs to be a recall to prevent injury or death.
When driving with the engine at lower than normal driving temperature, driver stops at a stop sign and with hard acceleration the engine surges from full power to dying out as tho fuel starved.this continues in a jerking action. Until; the driver removes his foot from the accelerator and then presses the gas feed again at which time the engine runs smoothly. This has happened on numerous occasions, however the dealership can find nothing wrong as the engine is now at normal running temp. Driver was told the problem is in the throttle body of the fuel system --- help..
