“During a road trip, we came to a stop and upon stepping on gas to proceed on the road and it wouldn't go. The engine revved and "pulled" until we were able to move. We took it to a dealership as well as private mechanic and was told it is an engine problem and running $3k or more to have it fixed. We have small children and consider this a safety hazard. Unfortunately, this is the only vehicle we have to commute.”

“Was driving approximately 45MPH and the truck just slowly powered down and "Engine Power Reduced" and eventually cut off and wouldn't crank back up. Got it towed to the Chevrolet dealership and was told the engine has to be replaced due to the bottom of the motor and the crankshaft in cylinder one. Was told it would be 17k to repair it.”

“For several months my check engine light has been flashing when I’m driving, especially on the highway. At times my vehicle feels sluggish. I press further own into the gas pedal and I am not getting adequate propulsion. It also feels like this when I’m going up a hill. I brought the vehicle to two independent service centers to get a diagnostic. One indicated getting misfire readings on two cylinders. The other indicated getting misfire readings in three cylinders. As you would imagine this is an extremely concerning safety risk.”

“General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time. As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.”

“General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system. Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.”

What this check cannot seeYou still need to check the service history, title, accident history, repairs, and the car’s condition.
  • ConfigurationPartial

    This model year came with 4 engine and trim setups, including 6.2L 4-Wheel Drive and 6.2L Rear-Wheel Drive and 5.3L 4-Wheel Drive and 5.3L Rear-Wheel Drive. Some problems only affect certain setups.

    What to do: Enter the VIN, or check the door label or window sticker for the engine and drive type.

  • VIN recall & historyNot verified

    This page cannot confirm open recalls, title records, or odometer history for one VIN.

    What to do: Check the VIN with NHTSA and get a title and history report.

  • Repair costNot verified

    We do not have a sourced repair cost for the listed problems.

    What to do: Get a written repair estimate for the named issue from an independent shop before you negotiate.
