Car initially started stuttering on the high, check engine and traction control lights came on. I immediately went to the nearest Chevy dealership a mile away. Initially I had 20 error codes. The problem was the Left side lifters 4 of 8 stop working. Dealership recommended Replace Left lifters, 2 push rods, valve cove, head gasket. $5000. After starting the work. The technician could not repair the lifters because my camshaft is pitted and the RODS were rotating. Their recommendation is to replaced the whole engine to fully fix the problem. $12000 with 3 yr warranty. My SUV just 100kmiles.

Went into limp mode on 11/6/25, took to the dealership where they found metal shavings in the oil due to a “stuck solenoid ‘A’”. Originally said that I’d need a whole new transmission, decided to do the cheaper easier repair and just replaced the valve train (not my choice) got it back on 11/13/25. On 11/24/25 I was on a very busy highway, at a red light, hit the gas when the light changed and the car didn’t move. Just revved the RPMs, then it suddenly lurched/surged forwards. Took it back to the dealership and they said “it doesn’t have any codes showing”. This is not normal behavior for a 4 year old vehicle with less than 40k miles on it.

Statement of Incident and Repair Costs While driving on the expressway at approximately 70 mph in the express lane with my family in the vehicle, the engine suddenly began to stutter and run rough. Within seconds, the vehicle lost engine power, the oil light came on, and the check-engine light started flashing. The sudden loss of power caused another vehicle to almost collide with us from behind, narrowly missing my family when our truck slowed abruptly. Because of the immediate danger, we were forced to cross two lanes of interstate traffic to reach the shoulder as quickly as possible, putting my entire family at further risk. We were then stranded on the side of the expressway. The vehicle was taken to the Chevy dealership in DeMotte, Indiana. Their diagnosis determined a catastrophic engine failure caused by lifter failure, resulting in bent rods and damage to the camshaft. Despite widespread reports and known issues involving lifter failures in this model, there is no recall for this year and model. As a result, we were left to cover the full cost of the repair. The dealership did not provide a rental vehicle, even though this truck is our family’s only means of transportation large enough to safely haul all of us. Insurance would not cover the failure due to the numerous notices and documentation showing that GM/Chevy is aware of this problem but has not initiated a recall. Total cost of repair: $8,801.53, paid out of pocket. Of which we had to borrow and scrape to figure out how to pay for it, due to it being our only vehicle for our family. Now we are left with the uncertainty as to whether the same thing will happen again, endangering the lives of our family yet again, due to living out more in the country and having to drive 30+ miles one way to get to grocery stores etc… on roads that have a speed limit of 55mph rt 49 going north from south of the Kankakee river or the expressway again where the other incident occurred I65 by Lowell Indiana exit.

SERVICE BRAKES
The braking system on my 2015 Chevy Suburban LTZ failed at slow speeds in a parking lot. I have replicated the issue in both forward and reverse. My family's safety was put at risk in that while backing up out of a parking spot the brakes failed completely and I had to push extremely hard on the brake to get the vehicle to stop. That same behavior occurred while pulling forward into a parking spot, almost hitting the car in front of me. I took the vehicle into a Chevrolet dealer today indicating the symptoms and they said there was no recall attached to my VIN. This exact same behavior in my vehicle is described in [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES
When driving at low speeds the brakes do not work. The vehicle will stop, but it is very hard to get it to stop. You must push the brake pedal all the way to the floor to get the brakes to work. This does not happen all time it will just happen out of no were, this can be scaring. I looked up to see if our vehicle has any current recalls, which it does not. But on 9/19/2019 we had our vehicle in the shop and they did do a recall at this time. It was Increased Brake Pedal Effort. NHTSA Campaign # 19V645000 and this sounds like exactly what was happening. This was done when our vehicle had 60,000 miles on it and at the time it was having no symptoms. We had never had any brake issues at this time. Now our vehicle is having these issues and I feel that this safety issue should be another recall on our vehicle and should be covered and fixed as it sounds like the same issue. Please let me know what can be done about this.

ENGINE
My 2023 Chevrolet Suburban High Country (VIN: [XXX] ) suffered a sudden and dangerous engine failure while my wife was driving 70 mph on the interstate returning from our child’s sled hockey tournament in Ohio. The vehicle gave no warning lights, alerts, or diagnostic messages before the failure. While driving in the right lane, the vehicle began losing power and making a loud noise. My wife exited the highway and contacted OnStar, who told her the tow would take over an hour and only cover three miles to closest dealer, leaving her stranded in an unsafe area. She attempted to carefully reach a nearby dealership. During this attempt, the vehicle completely shut off and she lost all engine power. The vehicle lost all power making the final turn into the dealership coming to rest in the middle of oncoming traffic of a four lane road. The Suburban would not restart. A tow truck arrived and transported the vehicle to a dealership. When they arrived, the tow driver noticed smoke and a strong burning odor coming from the engine compartment and told her to move away from the vehicle because it could potentially catch fire. The vehicle was left in the lot with the hood open and positioned away from the building for safety. The dealership has determined the engine suffered a catastrophic failure and requires complete replacement. Multiple related components may also be affected. This occurred on a vehicle with only 54,000 miles that was purchased three months earlier. This incident created a serious safety risk for my wife, who was nearly stranded on an interstate and had to maneuver a powerless vehicle across several lanes of traffic. I am reporting this to NHTSA due to the sudden failure at highway speed, lack of warning, and potential fire hazard.

ENGINE, UNKNOWN OR OTHER
I was driving and then the vehicle started running rough. There was no indication or warning lights before this happened. This is a huge safety issue because I could have had a wreck and injured people and my very own family. I took it to a Chevy dealership. They inspected the suburban and number 4 cylinder had a pool of oil in it. And they told me it need a new engine. Which it has the L87 engine that all the GM recalls are on. However, they are telling me mine isn't on the recall. They don't know if GM is going to cover it because it has 111,000 miles and it's out of the power train. It's the same engine they're having trouble with engines failures on. And I believe mine should be under the recall.

POWER TRAIN, ENGINE, TRACTION CONTROL SYSTEM
The contact owns a 2019 Chevrolet Suburban. The contact stated that while stopped at a traffic light, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light and traction control warning light were illuminated. The contact pulled over to the side of the road. The contact continued to drive the vehicle; however, the vehicle hesitated to accelerate as intended. The contact was able to drive to the residence. The vehicle was then towed to the dealer, where it was diagnosed, and it was determined that the transmission had failed and needed to be replaced. The contact stated that, as per the two truck drivers, transmission fluid was leaking onto the street. The vehicle remained at the dealer unrepaired due to the cost. The manufacturer was notified of the failure. The failure mileage was approximately 95,000.

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
7/13/25: Car repeatedly jerking/shuddering/rough ride. A flashing check engine light came on for 10 or 15 minutes. After stopping car and restarting it, the check engine light went off. 9/15/25: Car jerking and another flashing check engine light. Took to dealership. They drove it and said no codes stored. Told it was probably the transmission "breaking in." Took home. Car continued to jerk/stumble. 8/28/25 to 9/15/25: Car jerking and flashing check engine light back on. Took to Autozone. A Random/Multiple Cylinder Misfire Code was detected (P0300). Took to dealership and confirmed P0300 Code stored. GM TAC engineers involved. Told they were unable to figure out why car was having multiple misfires. Returned car to me because no active code/light. 9/29/25: Car jerking and flashing check engine light back on. Got a warning of "reduced acceleration and drive with care." Car lost power. I have video of this and contacted On Star with report generated and P0300 code. On 10/1/25 on way to dealer, car making audible ticking noise. I have video of this. Took to dealer, the ECM was replaced and oil changed because it was "very dark" (in vehicle with 4,600 miles). Car continued to jerk/stumble. Told by dealer that problem would have to get worse before diagnosis could be made. 10/31/25: Jerking and another flashing check engine light with "reduced acceleration drive with care warning." Turned car off and engine light off. On Star report P0300. Took to dealer. The dealership was given the videos of check engine lights/reduced acceleration warnings and ticking noise video. All show problem happening around 1,200 rpms. Told by dealer on 11/11/25 that GM rep said they will not pay dealer for any work because no active engine light/codes. Told to pick up car. Asked dealer today for reason in writing, but no response. Very concerned about vehicle safety when repeatedly going into limp mode and flashing check engine lights with GM offering no solution.

ENGINE, POWER TRAIN
Our engine went at 100,800 miles, costing us $15k in June 2025. Then our transmission went 3 months later, now costing us another $7k. GM is offering very little financial assistance. It's quite inconvenient that these major mechanical issues occur right after factory warranty. It is at a dealer getting fixed, again, but how can this be ok with GM to see their product be such a failure for consumers? Recall or not, this has left a horrible taste in our mouth for GM/Chevy vehicles. We will no longer trust the longevity of their vehicles and will educate others to be weary on purchasing vehicles. We can understand mechanical failures over time, but not to this extent, and we're very disappointed in the customer service and available assistance for someone that just spent nearly $23k on a vehicle that's less than 5 years old.

POWER TRAIN
Transmission has to be replaced due to transmission slipping and delayed shifting under heat and prolonged highway driving. This issue also causes SUDDEN hard shifting, hard breaking, shaking of the steering wheel, along with grinding of gears!! This is a safety issue to to no warning signs at all along with a sudden drop in speed and power!! While driving on the interstate or highway this sudden change can cause the vehicles behind you to rear end you or cause a pile up!!! The driver has no control of vehicle when these issues happen!! A loss in control due to shaking of the steering wheel is a huge issue!!! Lack of shifting or hard shifting causes a SUDDEN stop of vehicle with no warning signs while driving!! It is going to cause a crash!!!! These are serious and dangerous issues that Gm will NOT do a recall for!! GM is aware of the issues due to Suburban, Tahoe and Silverado vehicles in the year models 2018-2023 having this reoccurring issue!!! I recall needs to be done to save someone’s life!!!!! I have only had my suburban for 8 months!! I was not made aware of this issue at all!!!!!! This also causes rough idle!!!!!!!!

ENGINE, FUEL/PROPULSION SYSTEM
My 2023 Chevrolet Suburban with the 5.3L V8 engine has experienced lifter failure twice within less than [20,000 miles]. Both times the vehicle developed a misfire, engine belt like noise and was diagnosed by the Chevrolet dealership as having collapsed AFM/DFM lifters. All oil changes have been done at the dealership using GM-approved oil. The issue appears to be a known problem on 2021–2023 GM vehicles with the 5.3L L84 engine. GM has a technical service bulletin (PIP5776H) regarding lifter collapse, but no permanent fix has been provided. I am concerned this could lead to engine failure or stalling while driving, creating a safety hazard.

POWER TRAIN, ENGINE
Purchased the vehicle on April 7, 2025. On 7/15/25, the car had 6948 mi. and started running rough, had a loss of power, an odor from the engine, and then on the display: check engine, blinking green vehicle light, and a message stating that the car was lowering for stability control. Took the vehicle to the closest Chevrolet service. The service dept. determined that code found P0307 and P0300, cylinder seven had the most misfires above 500. After completing oil service, the vehicle began to click on the passenger side; however, it was not misfiring. They inspected and found potential lifter issue. Found ticking coming from cylinder 7 and verified misfires. Found 2 pushrods damaged. Heard noise coming from cylinder 4, removed valve cover, removed rocker arms, and found 1 pushrod damaged. They removed and replaced all lifters and 3 pushrods. They stated there was no more noise //after this repair. These repairs were completed on July 25, 2025. On 8/15/25 took back to service because it continued to run rough and made excessive noise and whistling when starting the vehicle. The dealer inspected and heard the noise, inspected the vehicle exhaust leak, checked exhaust manifolds, pipe connections, and determined there were no issues found. On 9/26/25 at 11,821 miles the car was making excessive noise, running rough, and was losing power. Drove home, and the vehicle was running rougher and losing power. No check engine lights or warnings were present. Drove home, and the vehicle was running rougher and losing power until it turned off. Towed in. Maintenance techs determined catastrophic engine failure, all bearings and engine rods seized. After this repair hen the catalytic converter failed. This car has been out of service due to engine failures for 43 days out of the 204 of ownership.
