2009 GMC SIERRA 1500 — Problems, Recalls & Safety Data

This letter serves as a formal notice of concern and demand for accountability regarding the 2009 GMC Sierra LD, VIN [XXX] , owned by [XXX] . There are numerous documented complaints and safety investigations concerning premature tie rod failure in 2009 GMC Sierra models. While the 2009 model year may not have been subject to a sweeping, industry-wide recall specific to tie rods in the 1500 series, it is undeniably and consistently associated with premature steering component failure — including both inner and outer tie rods. The refusal to proactively address this defect, assign a broader recall, or take ownership of the recurring issue reflects a troubling disregard for consumer safety. Documented and Reported Issues Include: • Premature Wear: Tie rods becoming loose or failing between 50,000–100,000 miles, resulting in steering wander and excessive play in the steering wheel. • Clunking/Knocking Noises: Audible front-end knocking at low speeds, a well-known symptom of failing tie rod joints. • Severe Safety Risk: Instances where tie rods have separated or become dangerously compromised, directly affecting steering control. • Uneven Tire Wear: Excessive inner or outer tire edge wear caused by steering instability. • Recall 14V-246000: A related recall acknowledging improper tightening of tie rods where they thread into the steering gear rack — a defect that could cause separation and loss of steering control. The common symptoms — steering vibration, looseness, clunking when turning, and vehicle pulling due to misalignment — are not minor inconveniences. They represent serious safety hazards that endanger drivers, passengers, and the public. It is unacceptable for GMAC and General Motors to minimize or compartmentalize this issue when patterns clearly demonstrate a systemic steering component weakness in this model year. The presence of Recall 14V-246000 further demonstrates that the manufacturer was aware of tie rod-related risks ! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Early October my passenger side airbag deployed and I was sitting in the drivers seat and had just put the key into the key hole but did not turn the key to start the vehicle. 3 weeks later I was going into the passenger side of the vehicle and the key was in my pocket and the drivers side airbag deployed. Both times the vehicle was not started and the airbags deployed I called GMC and they had the vehicle towed to a dealer to investigate why the airbags deployed. They said it was a sensor that was corroded and that’s why the airbags deployed. I asked GMC, why didn’t the sensor left the driver know that it was going bad, just like it notifies the driver if you have low tire pressure or needs an oil change. I had no notifications that the airbags were going to deploy. I’m so grateful that no one was driving the vehicle when they deployed. GMC said the vehicle is not safe to drive so they had it towed from my house to the dealership and then back to my house however they said they are not taking responsibility for the deployment and said it’s my responsibility to get the airbags fixed. I told GMC that I was filing a complaint with you all. Thank you for looking into this matter.

The contact owns a 2009 GMC Sierra 1500. The contact stated that while driving at highway speeds, the vehicle hesitated while depressing the accelerator pedal. The traction control and check engine warning lights were illuminated. The contact used a code reader and discovered a misfire in cylinder #4, and performed a compression test, which verified that cylinder #4 was failing to maintain compression. The vehicle was taken to a dealer where it was discovered that there was a failure with the lifter in cylinder #4. The vehicle was not repaired and remained with the dealer for additional diagnostic tests. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 56,000.

To Whom It May Concern, I am submitting this report regarding repeated engine and valve lifter failures in my 2009 GMC Sierra 1500 with a 5.3L V8 engine, VIN: [XXX] . 1. Component/System Malfunctioned: Both the original engine and a replacement engine—professionally installed by a Chevrolet dealership—experienced valve lifter failure related to the Active Fuel Management (AFM) system. The most recent failure was sudden and unexpected. The engine may be available for inspection upon request. 2. Safety Risk: Engine failure puts driver and passenger safety at serious risk, particularly if the vehicle loses power unexpectedly while in motion. In both instances, the failure created unsafe driving conditions. 3. Reproduction/Confirmation: The issue was confirmed by a Chevrolet dealership during the initial engine failure and again more recently on the current engine, which is now exhibiting the same failure. 4. Inspection Status: The vehicle has been inspected by the same dealership that performed the original engine replacement. To my knowledge, it has not been inspected by GM corporate, police, or insurance representatives. 5. Warning Signs: There were no warning lamps, messages, or clear symptoms prior to the failure. The problem occurred without advance notice and did not provide an opportunity to address it before damage occurred. This is the second engine failure my truck has suffered from the same issue, even after dealership installation of a new motor. I urge the NHTSA to investigate whether this represents a broader defect in GM 5.3L AFM-equipped engines. It is unacceptable that repeated critical failures can occur in these engines with no warning and no resolution, even after following proper replacement procedures. Thank you for your attention.

Allison transmission - random hard shifts, random multiple DTC's, random limp mode. Clear codes and works fine until it doesn't. Might have to clear codes 3-4 times a day or it might make it a week before it goes into limp mode again.
