Impala Digital Fuel Gauge 30% ERRORS Update

[Impalian]

UPDATE --- on GM NOT fixing POOR 30% ERRORS on many readouts on the digital fuel gauge in the Driver Information Center on the Impala cars reported LAST YEAR!.

My Chevrolet Dealer was told LAST YEAR that they would do a recall and fix the POOR accuracy. The problem was only a simple software change. The dealer called me today after THEY were told that GM IS NOT GOING TO FIX THE DRIVER INFORMATION instrumentation !!!!!!!!!!!!!!!!!!!!!! AMAZING! First they say they will fix - I wait - and find out they are going back on their word! For a SIMPLE cheap fix!

ANY SUGGESTIONS on getting this fixed?

Details of problem reported last year on a post.

Purchased a 2002 Impala with a Driver Information Center (U68) option. Measured 'fuel used' (Gallons) accuracy by recording fill-up gallons for each filling station stop for 2 years & reset to zero after each fill-up. the THE AVERAGE INSTRUMENTATION ERROR has been 30% !!!! When the fuel used readout shows 10 gallons - it REALLY used 13 gallons! 30% ERROR! ALSO - since the MPG average and instantaneous MPG uses the fuel used data with the odometer distance data - THE MPG shows a 30% ERROR in GM's favor! If gauge shows 20 MPG - you are really doing 30% LESS! GM stated that this is satisfactory measurement accuracy! Since when, for almost any instrumentation package, can the accuracy be essentially WORSE than the regular gas gauge analog readout on the dash. I have had other fuel flow meters on other cars and thay have been very accurate! I checked with my friends, and their cars were very accurate. 1% 2% type of accuracy - NOT 30%!

Suggest that everyone out there with an instrument option - measure the accuracy. You may be very surprised if you have an Impala. Filling station pumps have to be accurate to meet State standards.

Why pay extra $$$$$ for an instrumentation option of 30% accuracy?

What should I do to get the above calibrated/fixed?

At the present time, GM WILL NOT FIX - or even attempt to recalibrate! The fix for this is NOT that complex!
