2012 Chevrolet Impala Owner Comments

problem #8

  • 50,000 miles


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..
