POWER TRAIN

Potential Consequences:

Truck just made a year old and killed on me in the middle of road. They are saying I need a new engine and maybe transmission. Could not shift truck into neutral, which left me stranded on busy road. For unsafe and had me nervous. Trying to get GMC to buy me out of this vehicle. Had same problem with 6.2 liter prior to this truck. Engine and transmission was replaced. They promised if I bought new truck, I wouldn’t have the issues and here I am again. This is terrible.

EXTERIOR LIGHTING

Potential Consequences:

The reverse lights don’t illuminate camera when you’re in a dark parking lot or area. If and when camera is relied on for reverse, you wouldn’t be able to see a person or anything else. It’s a lighting problem. When you are in an area that is lit (dealer parking lot) you can see fine. I also own a 2014 Chevrolet and camera works fine in dark and lit areas.

ENGINE

Potential Consequences:

I am beyond frustrated with my newly purchased 2024 GMC Sierra Elevation 1500 5.3l V8. Back in November I was notified to bring my vehicle back to the dealership for a complete engine replacement. Ever since this time I have had continuous problems with the vehicle. One day after receiving my truck back, I noticed that it was running rough and misfiring. When I opened the hood, I observed a bungy cord still attached to the engine. Several weeks after, the check engine light came on and took a week to get back due to sensor issues with engine. Today, after getting off work, I turned on my truck, but I am unable to shift out of park and I am stuck waiting on a tow truck. There has been nothing but issues with this truck since they replaced the engine. I am not sure if the mechanics at Garlyn Shelton GMC in Temple, Texas, are qualified to replace engines. This is a brand new truck and I should not be having these issues. My fear is that these problems are going to continue because they either did not properly install the new engine or there are still defects.

POWER TRAIN

Potential Consequences:

First time it happened was on November 28th 2024 around 8pm, turned de engine on, selected the reverse gear and stepped on the gas, the reverse gear was selected but the gear didn't worked at all. I almost hit a car that was passing on the street. I out the gear on drive and got the message "reduced acceleration". I believe that is a known issue by GM's 10 speed gearbox. The car is at the dealership and they informed me by e-mail that the part transmission valve body is in a "do not sell list". I have concerns about safety because losing power on a 70miles per hour road can be dangerous and not being able to reverse is also very dangerous. There are tons of posts about it in Facebook.

Potential Consequences:

I have experienced several occurrences of unintended acceleration while operating the vehicle at low speed. Two recent examples; 1) the truck accelerated rapidly while I was driving into my garage, and 2) the truck accelerated suddenly when pulling forward out of a parking spot in the morning shortly after starting the vehicle. In all cases, a hard application of the brake pedal slowed the vehicle. I considered whether this was operator error, possibly engaging cruise control inadvertently while turning the steering wheel, but the incident this morning does not support that potential cause. I have not spoken to the dealer about this issue.
