The 2023GMCTERRAIN carries 35 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 4 crashes, 2 fires, 2 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2023 TERRAIN is engine with 6 filings, followed by electrical system (5) and fuel/propulsion system (5). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 2 investigation files overlapping the 2023 TERRAIN. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

GMC Terrain with 12,564 total miles had experienced an engine failure. Under normal driving conditions, the car was sluggish and would not accelerate properly when pulling out into traffic or when getting on the freeway/interstate causing fear for driver safety and causing traffic slowdowns or congestion with a significantly increased risk of crash. While driving to work, the vehicle service engine light turned on and displayed "reduced engine power". Upon investigation the dealership found codes P0011, P0014, P0016, P0017, and quoted "Cylinder 4 intake rocker had fallen off and laying on head, found excessive debris and metal material around rocker 4, Found cylinder 2 intake rocker to be worn sideways.

While driving the fuel pump failed and started spraying gas everywhere in the engine compartment.
My son was making a left onto a freeway on ramp after traffic cleared and the steering wheel completely locked up resulting in him going over the curb and rolling completely over in a steep ditch. This occurred at a low speed (no more than 25mph), confirmed by the Life369 app. My son's description was that it felt like the wheels were against a wall and the wheel wouldn't turn even though he was using both hands in an attempt to turn. My son said there was no warning lights or any other indication that he noticed, other than the complete locking up of the steering. The resulting rollover into the ditch has totaled the vehicle so it was not inspected by any collision shop. I attempted to check the steering in the tow yard but the vehicle had no power.

My GMC Terrain was stopped in traffic at a Red Light. When I stepped on the gas pedal to proceed, the SUV shut-down. Could not move SUV in Traffic. Called Police and SUV was towed. SUV towed to GMC Dealer. The K111 Fuel Module was causing the problem. GMC Dealer Repair Shop removed and replaced the K111 Fuel Module. They claimed SUV is OK. I don't trust this SUV any longer. I read of similar problems with 2022 GMC Terrain and the Fuel Module defect causing the SUV to shut down. This is a safety hazard to the Driver and other vehicles on the highway.
