Displayed on the dashboard engine loss of power with check engine light on. Took to the dealer to repair and got quoted a spark plug change when the issue is clearly something else.

The engine lifter failed. The lifters collapsed on the highway. The inspection is available upon request. My husband was the driving on the highway and heard a tapping noise. All the engine lights came on and he pulled off to side of highway and was instructed not do drive the vehicle. The vehicle needed to be towed and was not drivable. The vehicle was towed to the dealer and confirmed if was the lifters which needed to be replaced. There were no warning signs, no lamps, no lights prior to the failure to alert something was wrong. After paying for the repairs at the dealer in the amount of $5,441.18 and other expenses, we reached out to Chevrolet Customer Assistance asking for them to cover the cost of this repair. We did not have time to get an extended warranty since this vehicle is new. With a vehicle having 56,000 miles on it, it should not be having engine problems. Our argument and frustration is GM knew of this problem on this particular vehicle and did not request a recall and this model. They refused to give us a full refund and gave us $2,720.29. We appreciate the assistance, but after doing research on this problem, this is a common concern and many customers have had to have their lifters replaced. GM knows of this issue and did nothing to correct their mistake. I have never experienced engine problems on any of the vehicles I have owned for over 10 to 15years old.

Dear NHTSA, The truck has lost electrical power several times over the past few months but only 3 times while driving. Today it completely shutdown while making a right hand turn at a busy intersection causing the loss of power steering and braking while narrowly missing a car waiting for the traffic light It took both hands to turn the wheel and both feet to push the brake pedal enough to stop on the shoulder. Prior to this latest incident I removed the engine compartment splash pan, checked the starter and ground connections and all seemed well. I then unplugged, cleaned and reconnected all electrical connections in the engine compartment and fuse box. The complete shutting down of a vehicle and its electric system while driving is a very dangerous matter. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The transmission locked up while driving such that we came to a stop in traffic with our newborn and toddler in the back seat and were required to call 9-1-1 because the vehicle was stuck in a gear and would not move while we were in the middle of a road in traffic. The problem has been confirmed by a dealer that the transmission blew due to metal getting into the transmission from failure of transmission pan. There was minimal warning before it happened. Approx. 8 months prior we had taken it in to dealer because the RPMs were running high and and we-??re told it was the 4 wheel drive causing it and approx. 2 weeks prior to this incident we heard grinding.

Was driving down the road at 65 and the truck shut down completely and had control of steering that time. Put truck in neutral and it restarted. Then was in a gas station getting gas then went to pull out after filling up and the wheels jerked and almost broke my wrist the instrument cluster said stibilatrac and shut down. Went to restart then the instrument panel said lower driver window then close. It did this one more time in the gas station parking lot.

I drive a 2017 chevrolet silverado 1500 lt 5.3 V8 Pickup. I currently have 86k miles on this vehicle. I am the second owner and lately have been experiencing loss of power, engine hesitation, poor fuel economy, and high oil consumption. I brought my truck to the dealer I purchased it from ( Koons Chevrolet of Tysons Corner VIRGINIA ) I brought the vehicle in for service because back in February I had the check engine light flash and the truck engine almost cutout (whilst traveling at high speeds )completely. This past week I was merging onto a highway and upon pressing the pedal to increase speed to merge safely the engine lost power completely for about 5 seconds and then magically regained power. During this i was almost side swiped and forced to drive on the shoulder almost crashing into the barrier wall. I had the info screen on my dashboard and was able to trace when this issue occurred. Upon switching from V4-V8 mode. Further research with a mechanic friend of mine revealed that Chevrolet has been using the same failing lifters since 2014 and it was a known issue, yet never recalled. How can I go about either fixing this issue or recuperating the sales price I paid for this faulty vehicle? I dont think it's right that the American tax payers bailed out general motors only for them to cut cost by way of reducing the quality of vehicles they were making... absolutely egregious. Please help. Sincerely, Unhappy Taxpayer ?

One random morning engine made funny noises. By time I left work engine light flashing and stability control wouldn-??t turn off. Dropped it off to dealership told me it-??s 4500 to fix one lifter that failed 7500 to fix all. They know it a problem that GM issues letter on what they recommend to fix, but no recall. My truck warranty expired on 10/2022 and incident happened on 01/2023 my truck had 32987 miles when dropped off after repair 32997 miles. If issue is know and class action in place why hasn-??t GM issued a recall.

The dash went dim, stabilitrac message came on the information display and the truck completely shut off. I had no lights no anything. I popped the hood touched the +battery terminal and lights came back on. Was able to drive home

Loss of power and misfire. I was on I44 in Oklahoma with my 1 year old and couldn-??t go over 45 MPH. The mechanic said it was a lifter failure and it ruined cam shaft. In all the total repairs were $3800. I-??m just learning about this common problem and seen there was a class action lawsuit filed.

- Blanchard, OK, USA

In my truck it goes from V8 to V4 and I want it to stay in V8 all the time. Also, I have 5.3 engine, and cuz it goes into V4, that means that the back 2 lifters isn't getting enough oil, which can cause those lifters to lock up. I think those trucks that have that issue need to be recalled, cuz if the lifters lock up it can cause the engine to lock up and cause the truck to have an accident and possibly hurt a lot of people. Also, yes there are tuners you can buy to stop the V4 part, but who knows what they can mess up in the computer part.

On 9/11/2017 i purchased this 2017 Chevy Silverado 1500 Custom double cab truck. I owned it for over 7 years. (46000 miles) And garage kept since day 1. I noticed a lot of rust on frame and Spair tire a lot. Also the paint on the body is chipping a lot. I did not have any problems with the lifter issue yet. But i feel as soon as it goes out of warranty I will have to deal with rebuilding my engine. GM knows of this problem and not doing anything about it. It would be nice if this engine could be replaced with none of the AFM parts and at no cost to me.

Fuel injectors are misfiring. This has caused the shifting of gears to be rough. Also, when at a complete stop, then a small amount of force is applied to the gas pedal, a sudden jump forward will take place. Check engine light and the traction control lights have came on.
