I was rear ended at approximately 8:00 am this morning. Both my vehicle and the truck that hit me likely suffered damage that will result in them being totaled by the insurance companies. I have a major concern about my airbags not deploying.
Takata recall local dealer continues to refuse to replace defective airbag involved in gm recall 49151 issued in a july 2016! This vehicle was purchased in louisiana and has spent much of its life there - louisiana is considered a critical, first priority area under you recall.
Engine failure at 64,000 miles. Drove vehicle from home and then vehicle immediately began shaking violently. Truck driving fine up until that point. No warning signs. No check engine light beforehand. Vehicle now at gmc dealership and needs new engine for up to $10,000. Gmc is not covering the expense.
The interior door handle chrome is peeling off, and it cut my wife's hand today. There are 3 of the 4 doors that have it peeling, and I am worried one of my children will cut there fingers also.
After I bought it, I notice the engine bay was real rusty like its been in water or driven over lots of water. I didnt get a car fax at time of purchases but did car fax myself , and it appeared that vehicle is from new orleans. With all the dirt and grim coming out of vehicle its diffently from new orleans.
Complete perforation of frame by rust, impacting ability to securely mount front anti-roll bar. Discovered in march of 2016. Gm has offered no resolution.
