Defect Description:
POWER TRAIN
Potential Consequences:
Dear NHTSA, I am submitting this complaint to report a recurring and potentially dangerous issue with the transmission in my 2018 Chevrolet Suburban, which I purchased brand new in 2018. At approximately 60,000 miles, I experienced severe transmission issues that led to a complete transmission replacement. Now, at around 133,000 miles, I am encountering the same symptoms once again. The transmission makes a loud clunking noise during acceleration and braking, and shifts gears abruptly and harshly. These symptoms appeared suddenly, with no warning lights or prior alerts. This problem poses a significant safety concern. The vehicle sometimes struggles to accelerate properly, making it dangerous to merge into traffic. Additionally, the forceful shifting makes the vehicle feel unstable and unpredictable, as though something beneath the car might fail while in motion. I transport my husband and our children in this vehicle, and this issue puts all of us at serious risk. I have scheduled another appointment with a GM dealership to inspect the vehicle. However, given that this is a recurring failure involving a critical system, I am requesting that NHTSA investigate this matter as a potential defect affecting other owners of the same model. Thank you for your attention to this serious concern.

Defect Description:
POWER TRAIN
Potential Consequences:
My Suburban is having the same issues as the most recent recall on the 2021-2025 Chevrolets. The issue is with pretty much all of the motors that go from the V8 to the 4 cylinders. It's doing the same exact thing a friend of mine's 2019 Tahoe did. It's making a loud knocking/ticking noise. When you first get to going it starts almost sputtering which can cause issues if you're in oncoming traffic trying to cross roads.

ENGINE
Potential Consequences:
Currently own a 2018 Chevy Suburban with a lifter issue in the engine. This is a known issue with Chevy as many vehicles have experienced this problem from zero to over 100k miles. Chevy has not issued any help or support with customers with this issue. My vehicle is well maintained I get oil changes frequently and have never not done a required service when needed. When I notice an issue I immediately take it to in Regal Chevy for repairs and no matter what the issue is I get it repaired on the spot. I find it odd that this is a recurring issue and Chevy has done nothing to help support loyal customers.

WHEELS
Potential Consequences:
Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.

ENGINE
Potential Consequences:
Car abruptly lost power while driving causing rapid deceleration and requiring immediate action to steer vehicle off the active roadway without hitting other vehicles or causing property damage. There were no warning lights or signs until this occured. The vehicle was later towed to chevrolet who informed us that this was a KNOWN ISSUE these cars have where their "lifters fail and sometimes even damage the camshafts" If this was a known issue why would it not have been addressed in a recall. After speaking with the dealer I searched the internet for the same issue and it is widespread across several GM cars including mine. GM now wants $3,100 to repair a dangerous manufacturer defect.

Performed battery test, voltage was low at 16%.Battery(new FY22) failed load test. Found starter making "thunking and clicking" sounds. Unable to move shift lever out of park position. Let battery charge an additional 1 hour and found battery failed testing. Tester states "short" which indicates internal failure. Tested starter draw, found excessive draw at 400amps, spec is 70-120amps. After testing tried to start. Engine turned over slowly for approximately 1 second and then made clicking sounds. Found body module voltage codes returned. Verified engine does turn over when manually turned with breaker bar. FURTHER SHIFT LOCK ISSUES OR OTHER ISSUES.

Determined/Suspect; The shift lock actuator/gear shifter is faulty.
Additional Notes:
TECHNICIAN - Was unable to perform test drive of vehicle. Inspected operation & found; Vehicle will not turn over, battery very weak. Removed battery, put on charger for approximately 45 minutes. Reinstalled battery. Vehicle had power but did not start. Was unable to get shifter into neutral. Found engine still not turning over. Found starter motor making clicking sounds. Got to turn over once but was very labored, but did not start. Disconnected shift cable at transmission and rolled vehicle into shop for diagnostic. - Scanned computer control modules & found; Approximately 30 codes total in multiple modules, with high and low voltage codes. - Inspected & found; Performed basic electrical faulty tracing. Performed battery test, voltage was low at 16%.Battery(new FY22) failed load test. Found starter making "thunking and clicking" sounds. Unable to move shift lever out of park position. Let battery charge an additional 1 hour and found battery failed testing. Tester states "short" which indicates internal failure. Tested starter draw, found excessive draw at 400amps, spec is 70-120amps. After testing tried to start. Engine turned over slowly for approximately 1 second and then made clicking sounds. Found body module voltage codes returned. Verified engine does turn over when manually turned with breaker bar. FURTHER SHIFT LOCK ISSUES OR OTHER ISSUES. Technician removed and replaced the starter assembly and the battery. Found engine started up and ran. Verified repair. Found shift lock still not working. Shifter will not leave the park position. Performed testing. Verified transmission will shift to drive and to reverse. Verified brake switch working properly and sending signal out to ABS module. Verified shift cable not frozen. Found no fault tracing available for this type of shift lock. Eliminated other possibilities which indicates the issue is with the shift lock actuator/gear shifter. Determined/Suspect; The shift lock actuator/gear shifter is faulty.
