2005 Chevrolet Tahoe Problems

What owners report

Complaints on this model year are dominated by instrument cluster failures: owners report speedometers that read wildly wrong or quit entirely, often around 50,000-100,000 miles. Fuel system problems (refueling difficulty, fuel odor) and corroded brake lines are the next most common themes, with transmission and steering complaints appearing at higher mileages.

1. 1
   Electrical system

   Speedometer and instrument cluster failure

   • 85 complaints (29%)
   • median 64,030 mi at 4.2 yrs old (71 state mileage)
   • owner-quoted repair $450 (median of 9 quotes)
   • filed 2007–2020

   Owners describe the speedometer needle jumping, reading far above the actual speed, sticking at a fixed number, or dropping to zero while driving. Several say the display would sometimes work after restarting the vehicle, then fail permanently. Dealers typically diagnosed a failed instrument cluster or cluster drive motor and quoted replacement, and some owners were told their vehicle was not covered because earlier model years had a related campaign. Reported from about 32,000 to 140,000 miles, with many complaints filed between roughly 45,000 and 70,000 miles.

   What to check: Verify the speedometer against a GPS or phone app at several speeds during a test drive, and check that the odometer and other gauges read consistently. Ask whether the cluster has been replaced or repaired.

   “The speedometer on my 2005 Tahoe is reading incorrectly. The other day I was traveling down the interstate when I looked down at my speed and the gauge was reading 120mph. I pulled off at the next exit when I came to s a stop; the speedometer was indicating 60mph. It has been 3 days since this happened and it still gives the same false readings.”

   NHTSA complaint #10250211, filed 2008-11, 47,600 miles

   “The speedometer would not decrease speed, and but would register an increase, and consequently would not reflect actual speed. I could correct problem by repeatedly starting vehicle, until eventually it just would no longer register a change in speed at all. Now I have no idea what speed my vehicle is traveling.”

   Fuel system

   Fuel pump, EVAP and refueling problems

   • 27 complaints (9%)
   • median 80,000 mi at 8.1 yrs old (25 state mileage)
   • filed 2005–2019

   Owners report a strong fuel smell inside or outside the vehicle, and in several cases a fuel pump replacement was needed. Others describe the fuel nozzle shutting off repeatedly or fuel spitting back out of the filler neck during refueling, which they attributed to the EVAP purge canister solenoid. Complaints also mention a fuel gauge that reads inaccurately or a low-fuel light that stays on with a full tank. Mostly reported between about 50,000 and 130,000 miles, at ordinary daily-driving conditions.

   1 related service bulletin

   What to check: Smell around the filler neck and under the rear of the truck after a fill-up, and try fueling at a normal pump rate. Check that the fuel gauge responds promptly after refueling and that no warning light stays lit.

   “Every time I start my vehicle, my gas light goes on and indicates I am low on fuel when I have gas in it. After driving for awhile the needle will go up but it is not giving an accurate reading of how much gas is in the tank.”

   NHTSA complaint #10248379, filed 2008-11, 50,000 miles

   “2005 Tahoe-due to faulty purge canister solenoid (evap) cannot put gas in vehicle due to the air has nowhere to escape while filling. Gas spurts back out of fuel neck causing potential safety and environmental hazard. Gm has a new redesigned part but does not replace or repair at their cost. Consumer is getting charged and required pay for their acknowledged problems.”

   Transmission and drivetrain

   Shift lever position indicator not lighting

   • 13 complaints (4%)
   • median 92,000 mi at 6.1 yrs old (11 state mileage)
   • filed 2005–2022

   Owners describe the gear position indicator in the instrument cluster failing to illuminate, making it hard to tell which gear is selected. Some complaints note the vehicle was not covered by the existing campaign for this condition and were told the cluster needed replacement. Others describe the transmission slipping out of drive into neutral or intermittent harsh shifting. Reported from about 56,000 to 141,000 miles.

   Recall 05V0550001 related service bulletin

   What to check: With the engine running, check that the cluster shows the selected gear in every position. During a drive, confirm the transmission engages each range firmly and does not slip out of gear.

   “Shift indicator does not illuminate. Called dealership in reference to the 05v055000 recall that I assumed was applicable to all tahoes with the same problem. Service tech inicated that my VIN was not part of the recall. Seems that the recall should be expanded to include all of the same vehicles since the problem seems to affect the all.”

   NHTSA complaint #10958825, filed 2017-03, 130,000 miles

   “The shift lever position indicator located in the instrument panel cluster does not illuminate at various times. This has happened on and off for a while and I decided to research the issue. I found a similar recall for this model year vehicle on your website, but GM refuses to cover the defect on my VIN. I recently almost hit someone being in the wrong gear. This matches a previous recall id of 05v055000.”

   Brakes

   Corroded brake lines and brake fluid loss

   • 18 complaints (6%)
   • median 89,500 mi at 9.4 yrs old (17 state mileage)
   • filed 2010–2018

   Complaints describe brake lines rusting through, especially where the lines run along the frame rail toward the rear axle, leading to a sudden loss of fluid and a pedal that goes to the floor. Owners say the failure came without warning lights beforehand. In several cases the vehicle was towed and the lines replaced, and some owners noted the dealer had seen the same corrosion on similar trucks. Usually reported on vehicles around 63,000 to 130,000 miles and roughly 7 to 10 years old.

   Recall 05V103000

   What to check: Have the steel brake lines inspected along the frame rails and above the rear axle for rust or seepage, and ask whether any have been replaced. Confirm the brake pedal feels firm and the fluid level is correct.

   2 excerpts from owner complaints in NHTSA records

   “Brakes failed due to rust in the brake lines causing them to rupture without any warning while vehicle was in motion. Luckily accident was avoided due to low speed on a residential road. Young children were traveling in the vehicle. All brake fluids were immediately lost and brake pedal dropped all the way to the floor and did not slow vehicle at all. Dash warning lights did not give any forewarning! Vehicle is only 7 years old.”

   NHTSA complaint #10442425, filed 2012-01, 105,000 miles

   “Lost brakes getting off interstate 20/59, seems to be a corrosion issue on the brake line going to rear axle. The location of the leak relative to the body is at the 2 l door along the frame rail.”

   NHTSA complaint #10482824, filed 2012-11, 110,000 miles

Buying note. Check the speedometer, fuel gauge and gear indicator against real conditions on a test drive, since cluster failures are the most frequent complaint here. Have a shop inspect the steel brake lines and the fuel filler/EVAP system before purchase, as both come up repeatedly.
