    My car sometimes cuts off while driving. Was on highway 301 running about 60 mph in the middle lane and just lost power no warning. No code no nothing. Sacred me, I truly feel that's a safety issue, for me and the cars behind me. It's bad not knowing when or where this will happen again.

    Ignition lock issue. I’m guessing security light came on hard to start vehicle when switch doesn’t work. Almost left me stranded. Apparently this is common. I have kids and if I get stranded with them what am I supposed to do? Something needs to be done

    I have a 2003 Chevrolet Impala! Look it up on the internet, and you will see that the failure rate of the GM passlock system is huge, and massively expensive to repair! In fact from a inside relative, says GM makes more money in parts, and repairs than on selling a new vehicle! This is without doubt a premeditated flow to rip off the public! This is in fact insensitive for GM to engineer a constant, and ongoing failure of the of its vehicles! This passlock defect can not be fixed by accessing the cars computer! It should be that easy but it is not a option. Being stranded by this defect is life threatening. The problem is the Passlock system that has failed for me, and hundreds of thousands owners of GM vehicles, and tens of millions of dollars in repairs that GM should be forced to repair, at no costs, past, and present to the owners, and including towing, and a rental car! The passlock defect, and failure completely locks up the cars entire electrical system, so the owner can not start, or even open the trunk of their car in a emergency! After it happens you can’t even access the car radio to reset back to the original factory functions! Even if you disconnect the battery, to get this accomplished, it will be a short while before it happens again! It is crazy expensive just to diagnose this problem! Please note that this is not just a Impala problem! This passlock defect falling involves dozens of Models of all types, old, and new. These vehicles number in the many hundreds of thousands over decades! Many tens of millions of dollars in repairs, and hundreds of thousands waiting to happen! This needs to be addressed at a government level! We won’t to see some consumer protection, and Justice! Thank you for your time, and consideration!

    Traveling at 58 mph in Cruise Control for 10 minutes I increased speed with 4-6 rapid pushes of the Accelerate button in less than 1.5 seconds, Each push is 1 mph. I have never pushed it that rapidly.The engine acted as if I floored the accelerator & the transmission went from 4th to 3rd gear, speed went to 70+ and rapidly increasing. I stepped on the break pedal several times to disable CC but no help, I switched the CC button to the off position several times, no help. Now at 85+ and accelerating hard in wide open throttle (WOT). I shift to Neutral and turned the ignition to the ACC position to retain steering ability as the engine was RPM'ing out to destruction. I coasted off the highway and set ignition to off. After a few minutes I turned engine on and it rev'd out of control, still WOT. Ignition off did not reset the problem. I opened the hood to disconnected the battery & I observe that neither the CC or accelerator cables are not holding the throttle body (TB) in "WOT", it was closed in an idle position. It is not mechanical. I disconnected the battery for several minutes and then the system operated normally. I have used CC a million times but never have pushed that accel button that fast. I served 7 years as a Reactor Operation onboard US navy Fast attack Submarines, have torn apart and assemble mechanical and electrical reactor systems. I have been a Hardware Engineer for 40+ yrs and have 10 US patents in fault tolerant server design. I've been a car guy since 5 yrs old. This is a problem with the cars computer or its code. The rapid pushing of the CC accel button is key here as well as memory retaining this CC state after Key OFF. Its a good thing I experienced with many hard casualty life and death situations while serving, because my car was accelerating out of control, my experience and training in the US Military taught me to keep cool and think.You really should investigate this. I can tell you more specifics but I'm character limited.

    ON 3/21/2021 I WAS DRIVING ON THE FREEWAY FOR ABOUT 25 MILES, WHEN MY 2003 CHEVY IMPALA STARTED MAKING A WHINING NOISE AND IT CONTINUED TO GET WORSE WITH EACH TURN. MY HUSBAND SOON REALIZED IT HAD TO BE THE POWER STEERING FLUID. SO HE PUT A BOTTLE OF POWER STEERING FLUID IN AND AFTER STARTING AND DRIVING FOR A FEW MINUTES THE CAR WAS BACK TO NORMAL! SO I PROCEEDED TO GET BACK ON THE FREEWAY TO HEAD HOME. AS SOON AS WE GOT TO OUR EXIT ABOUT 23 MILES FROM WHERE WE HAD JUST PUT THE FLUID IN. IT STARTED MAKING THE SAME WHINING NOISE. SO BACK TO THE STORE FOR MORE POWER STEERING FLUID. HE FILLS IT UP. THE NEXT MORNING SAME PROBLEMS. WE KNOW NOW THERE IS A LEAK IN OUR POWER STEERING BUT NOT SURE WHERE EXACTLY. MY CAR NOW SITS AS WE CAN'T AFFORD TO BE ADDING BOTTLE AFTER BOTTLE OF POWER STEERING FLUID TO MY CAR EVERYTIME WE NEED TO GO SOMEWHERE. MY HUSBAND BELIEVES WE HAVE RUN INTO THE SAME ISSUES THAT HAVE RECENTLY BEEN REPORTED BY NHTSA ID# 11316116 BEING POWER STEERING RETURN HOSE RUBS AGAINST SOME PART OF THE MOTOR AND RUBBER HOLE IN POWER STEERING RETURN HOSE.

    VEHICLE SHUTS OFF WHEN MOVING,TURNING OR STOPPED AT A TRAFFIC LIGHT. BY SWITCHING TO NEUTRAL, THE ENGINE MAY START AFTER 1 OR MORE TRIES. SO FAR THE FAILURES HAVE BEEN ON CITY STREETS AND HIGHWAYS. BUT NOT INTERSTATES. THE FAILURES ARE MANY BUT UNPREDICTABLE.
