Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Emissions
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
NA
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2003 Chevrolet Tahoe owners. The owner comments describe problems respondents experienced with this vehicle.

Climate System

Blower (fan) motor, A/C compressor, condenser, evaporator, heater system, automatic climate control, refrigerant leakage, electrical failure.

What Owners Say

A/C compressor

"Compressor failure, loud screeching noise, very expensive to repair or replace. Not fixed yet, I simply unplugged it."

Ward S., BC (2003 Chevrolet Tahoe LT 5.2-L V8)

"The a/c system would blow a fuse every time we accelerated. Turns out it had something to do with a faulty condenser. Afterwards ($1500) repair it works. Thankfully"

Anonymous, TN (2003 Chevrolet Tahoe 4.7-L V8)

"The air conditioner wasn't working. At first they said it was the belts, they replaced those but when accelerating, the belts would break. Another mechanic said the compressor? needed replacing, after that it's been doing well. Air is working great and taking off is not an issue with belts breaking."

"Not sure! it broke had to replace it, 3rd transmission!!"

Anonymous, CA (2003 Chevrolet Tahoe LT 5.2-L V8)

"First let me point out this was a replacement transmission that did fail. I got in the truck and started driving normally. I came to a stop and tried to go but it was struggling hard. I moved the shifter to low 1 and it down shifted to second gear. I shifted back to drive once I got moving and it shifted to 3rd then to 4th. At the nest stop it was not in first gear again. It felt like stuck in 3rd or 4th. I downshift again to get under way. After a few searches I found this was a common symptom of an electrical solenoid problem and ordered the solenoid kit. Once I removed the pan to install the parts I found several small fragments of brass and aluminum in the bottom of the pan. At that time I called up the trans shop and told them I would have a trans for them on Monday morning. I got it back a week later. Installed it. shifts better than it ever had.

"CHEVROLET has had issues in the past with their wiring. Certain model years received wiring from Mexico, which after about 10 years, for some reason just disintegrates.

Jim-Jennifer P., IA (2003 Chevrolet Tahoe LS 4.7-L V8)

"Suddenly, the airbag warning light came on. A check online revealed that in many 2003 Tahoes, there is a faulty ground wire under one of the front seats. According to a number of people on Youtube, the problem is that the ground wire is too short, and, when seat is constantly moved, it eventually breaks the ground. Judging from the number of comments, I would have expected at least a TSB about the problem."
