2023 Chevrolet Tahoe Reliability Report

Most of these reports are about recall 25V274000, not a new failure. Owners got the recall notice, but repair parts are not available, and dealers confirm the shortage. Many of these owners have had no failure yet. The other reports describe the same engine trouble seen elsewhere. That includes heavy oil use with "Add Oil" warnings, sudden power loss at highway speed with a low oil pressure warning, and a crankshaft failure that led to a second engine replacement.

The brakes lose power or fail completely, usually while a cluster of warnings appears: Brake System Failure with a 43 mph top speed, plus ABS, traction control, ESC, and brake pad messages. Some trucks lose brakes pulling out of a driveway. Others lose them exiting the highway, with the pedal going almost to the floor. One truck locked in ABS and could not move in -15 degree weather. Another brakes on its own at highway speed, hard enough to make the tires screech. Dealers often find no codes, and repairs do not always last. This is a direct crash risk.

The front windshield wipers stop while driving in rain or snow, sometimes at 60 to 70 mph, leaving almost no visibility. The washer and rear wiper may keep working. The wipers usually come back after 20 to 25 minutes or several restarts, and no warning appears. Dealers often cannot reproduce the problem. A software update and a new windshield sensor each worked for only a few months. Repeat failures are reported around 32k and 37K miles.

Airbag warnings come and go. Some owners see a brief light with a chime. Others get a recurring Service Safety Restraint System message, which one owner links to an under-seat airbag connector problem known on 2021 models. In one crash report, a rear-end collision at 45 to 60 mph set off no airbags, and automatic emergency braking did not activate. Only 4 complaints are on file. The one mileage given is 39,144.

A Service Steering Column Lock warning appears along with a full dash of brake, traction control, and ESC alerts, usually while the brakes go soft or stop working. One report describes loose, vague steering during this kind of event at freeway speed. Another truck showed column lock faults at 50 miles and had the system replaced twice over 18 dealer visits without a lasting fix. Dealers cite communication codes. There are only 3 complaints, and they track closely with the brake failure reports.

The factory running boards get very slippery in light snow or other light winter weather, and one owner reports repeated near falls getting in and out. In a separate report, the automatic liftgate closes by itself when a foot or a pet passes near its sensor while the gate is open, including during loading. These are the only 2 complaints on file, so neither problem is a broad pattern yet.

Both reports here repeat problems seen in other categories. In one, the truck has trouble starting, then lights every dash warning, including Brake System Failure, and the brakes do not work. This has happened more than once and cleared up by itself. The other describes knocking, high RPM, a blinking check engine light, and the feeling that the engine is about to lose power on the highway. Only 2 complaints are on file.
