2019 Chevrolet Colorado Reliability Score & Common Problems

Owners of the 2019 Chevrolet Colorado frequently report issues with the ignition system, where keys get stuck and cannot be removed, sometimes requiring battery disconnection to resolve. This problem often begins intermittently but can become persistent, with some owners noting this across various model years. Additionally, multiple complaints highlight transmission-related shuddering and delayed response, particularly during acceleration or gear shifts. One report involves a fire incident where the vehicle lost power and brakes, requiring emergency measures to stop. These issues appear across various mileages, with some occurring as early as 4,000 miles, and may have significant safety implications, including potential vehicle fires and loss of control.

Owners of the 2019 Chevrolet Colorado frequently report engine-related issues, including a blown head gasket, high pressure fuel pump detachment, and a malfunctioning thermostat. Symptoms described include loss of power, sudden acceleration, and coolant mixing with oil, often occurring around 34,800 to 41,000 miles. A notable safety concern involves a fire incident following vehicle shudder and smoke, leading to a complete vehicle loss. Additionally, multiple complaints highlight issues with the variable valve timing system and oil filter adapter, which can result in engine failure if not addressed. These patterns suggest potential reliability challenges for prospective buyers, particularly regarding engine components and associated safety risks.

Owners of the 2019 Chevrolet Colorado frequently report issues with the brake system, primarily involving vacuum pump failures. Common symptoms include the brake pedal becoming stiff and unresponsive, sometimes going to the floor, which significantly impairs braking ability. These issues occur at varied mileages, with some reports at approximately 21,000 to 130,000 miles. Safety implications are notable, as multiple owners describe situations where the inability to brake effectively nearly led to collisions, particularly in high-traffic or emergency situations. Additionally, some owners mention related problems such as grinding brakes and the need for rear brake pad and rotor replacements at lower mileages, suggesting potential maintenance concerns for prospective buyers.

Owners of the 2019 Chevrolet Colorado report issues primarily related to the high-pressure fuel pump and fuel leaks. Multiple complaints describe the fuel pump mounting bolts breaking, which leads to a loss of power and potential gasoline leaks. Additionally, some owners mention fuel leaks from the top of the fuel tank, attributed either to the fuel pump seal or external damage from road debris. These issues often occur around 24,000 miles, with symptoms including reduced vehicle speed and visible fuel leakage. Safety implications include the risk of fuel leaks, which could lead to fire hazards if not addressed.

Owners of the 2019 Chevrolet Colorado frequently report issues with airbag non-deployment during crashes. Complaints consistently mention that the airbags fail to deploy in rear-end and head-on collisions, even when the vehicle sustains substantial damage or is declared a total loss. These incidents involve vehicles traveling at speeds ranging from 32 to 40 miles per hour. The reports include three crashes resulting in five injuries, indicating a potential safety concern for buyers considering this model.

Owners report issues with the engine and cooling system of the 2019 Chevrolet Colorado, primarily involving oil leaks and temperature gauge malfunctions. Complaints frequently mention oil leakage due to a valve cover gasket, which in one case reoccurred and was later attributed to a failed camshaft carrier gasket. Additionally, some owners describe problems with the temperature gauge not functioning and the engine light remaining on, often accompanied by transmission slipping. These issues have been reported at mileages around 40,000 and 112,000. No crashes, fires, or loss of control have been reported in connection with these complaints.

Owners of the 2019 Chevrolet Colorado report issues related to the suspension, with symptoms including abnormal roaring sounds from the rear and shuddering while driving at various speeds. One owner describes a severe incident where the front passenger control arm broke, causing the wheel to collapse and resulting in a loss of steering and an abrupt stop. This incident occurred at approximately 15 mph on a gravel driveway, with no prior warning signs or external impacts. The mileage at the time of these issues is noted around 9,000 miles. The control arm failure has safety implications, as it led to a crash, though no injuries were reported. These reports suggest potential concerns for used car buyers regarding the vehicle's suspension integrity.
