2024 Chevrolet Tahoe

Issue: 
On certain vehicles, the connecting rods and/or crankshaft components may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. 
Note: This recall only affects certain vehicles equipped with a 6.2 L V8 gas engine. 

Safety Risk: 
An engine failure could cause a sudden loss of power to the wheels and increase the risk of a crash. 

Corrective Actions: 
General Motors will notify owners by mail and advise you to take your vehicle to inspect and, if necessary, repair or replace the engine. For vehicles that pass the engine inspection, the dealer will replace the oil with a higher viscosity oil, install a new oil fill cap, replace the oil filter, and add an insert to the owner's manual.

Issue: 
On certain vehicles, a software problem could cause the low brake fluid warning lamp not to turn on if the brake fluid level gets too low. A low brake fluid level can cause reduced braking. 

Safety Risk: 
A driver that isn't aware of a low brake fluid level could experience reduced braking and an increased risk of a crash.  

Corrective Actions: 
General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the electronic brake control module software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.

Issue: 
On certain vehicles, a software problem could cause the lower beam headlamps not to turn on as it becomes dark outside if the multi-function switch is in the "OFF" or "PARKING LAMP" position. This could also cause the daytime running lamps (DRLs) to turn off when the vehicle is moving. As a result, the vehicles may not meet certain requirements of Canadian regulations. 

Safety Risk: 
Headlamps and/or DRLs that don't turn on could reduce visibility, make the vehicle less visible to others and increase the risk of a crash. 

Corrective Actions: 
General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the body control module (BCM)software.
