2005 GMC Envoy XL 370

No clear pattern

0% of complaints about the 2005 GMC Envoy XL 370 arrived in its first year of service.

The figures below are reported without a verdict. The most-reported system is fuel system (42 complaints), typically at 6.0 yr or about 67,000 miles.

Complaints: 133
Median age at failure: 6.3 yr

Electrical system 38,000 mi 3.5 yr in service

#1 PROBLEM-- I ONLY HAVE 40,000 MILES ON MY CAR AND BOUGHT IT LESS THAN A YEAR AGO. MY FUEL TANK DOES NOT WORK-- IT FLOATS AND I NEVER KNOW HOW MUCH GAS I HAVE IN MY TANK #2 PROBLEM- DRIVING HOME LAST NIGHT-- I LOOKED DOWN AT MY SPEEDOMETER AND IT WAS STUCK OVER 120 MPH. I AM VERY UNHAPPY WITH GMC AND TELL EVERYONE I KNOW NEVER TO BUY ANY CHEVY VEHICLES-- THESE PROBLEMS SHOULD NOT BE HAPPENING SO SOON ON A NEWER VEHICLE. *TR

Electrical system 66,000 mi 5.3 yr in service

SPEEDOMETER ON MY 2005 GMC ENVOY XL IS PEGGED AT 120 MPH AND STAYS THERE ALL THE TIME EVEN WHEN THE VEHICLE IS OFF. I UNDERSTAND THAT THIS IS A WIDE SPREAD PROBLEM WITH GMC PRODUCTS. THERE IS A SERVICE BULLETIN FOR THIS PROBLEM ON MANY GMC PRODUCTS BUT DOSE NOT INCLUDE THE ENVOY LINE. WHY IS THIS? NO ACCIDENT SO FAR BUT VERY UNSAFE DRIVING A VEHICLE WHERE YOU HAVE NO IDEA OF HOW FAST YOU ARE GOING. *TR

Electrical system 68,000 mi 5.3 yr in service

GAS GAUGE NOT WORKING ON MY 2005 GMC ENVOY XL. FROM ALL THE COMPLAINTS SOUNDS LIKE THE FUEL LEVELING SENSOR WENT OUT. ONLY 70,000 MILES . I THINK WITH ALL THE COMPLAINTS THIS SHOULD BE A RECALL. *TR

Fuel system 33,000 mi 3.8 yr in service

I HAVE A 2005 GMC ENVOY I6 THAT I PURCHASED IN MARCH 2005. NOVEMBER OF 2006 WE REPLACED THE FUEL SENSOR THAT IS UNDER WARRANTY DUE TO WHEN I WOULD FILL UP THE GAS TANK THE GAUGE WOULD GO TO EMPTY AND WOULD EVENTUALLY MAKE IT TO FULL AFTER ABOUT 100 MILES DRIVEN. NOW A YEAR AND A HALF LATER THE SAME THING IS HAPPENING AND THE LOCAL DEALERSHIP HAS CONFIRMED IT IS A KNOWN ISSUE AND WOULD COST AROUND $1100 TO FIX THE ISSUE THAT SHOULD HAVE ALREADY OF BEEN FIXED THE FIRST TIME I TOOK IT IN. *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
