What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“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.”

“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…”

“VEHICLE DIDN'T START, SECURITY LIGHT WAS FLASHING, WAS TOLD TO TURN THE KEY INTO THE 'ON' POSITION AND WAIT EXACTLY 10 MINUTES BEFORE TRYING TO START IT. IT WORKED, BUT THE ISSUE BECAME WORSE AND WORSE UNTIL IT NO LONGER STARTED. WAS THEN TOLD TO REPLACE KEYS, DID THAT, SAME ISSUE. WHEN BLINKERS WERE USED, A LOUD BUZZING NOISE OCCURRED AND EVERY LIGHT ON THE DASH LIT UP, THE GEAR SHIFT LABELS BEGAN FLICKERING AND THE STEREO DID AS WELL. THE DEALERSHIP HAS REPLACED THE BCM AND THE IGNITION SWITCH, AND IT HAD FINALLY STARTED, UNTIL I WENT TO TRY TO GO SOMEWHERE. NO ONE KNOWS WHAT IS GOING ON AND MULTIPLE PEOPLE HAVE SAID THAT THIS ISSUE IS VERY COMMON IN THIS TYPE OF VEHICLE.”

“2003 CHEVROLET IMPALA 3.4L IS DIFFICULT TO START, REPLACED MANY PARTS TO TRY AND FIX: FUEL FILTER, FUEL PUMP, SPARK PLUGS AND WIRES, OXYGEN SENSORS, FUEL EVAP VALVE, AND THROTTLE CONTROL. VEHICLE CURRENTLY HAS 52,XXX MILES. SECURITY LIGHT FLASHES, WAS ABLE TO PULL ERROR CODE P1626: THEFT DETERRENT FUEL ENABLE SIGNAL NOT RECEIVED. KEYS ARE ORIGINAL TO CAR, I HAVE TRIED TO RE-LEARN KEYS TO VEHICLE WITH NO SUCCESS. NUMEROUS REPAIRS ARE LISTED UNDER THIS ERROR CODE, INCLUDING THE REPLACEMENT OF THE BCM, AND THIS DOESN'T ALWAYS FIX THE PROBLEM. THIS ISSUE NEEDS TO BE RESEARCHED FURTHER.”
