New Car Assessment Program

The 2003CHEVROLETIMPALA carries 935 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 44 crashes, 45 fires, 35 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2003 IMPALA is electrical system with 231 filings, followed by engine (88) and exterior lighting (57). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 8 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 57 investigation files overlapping the 2003 IMPALA, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

20231016ELECTRICAL SYSTEM

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 no

20211013VEHICLE SPEED CONTROL:CRUISE CONTROL

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

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.
