ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE
The contact owns a 2018 Chevrolet Silverado 1500. After starting the vehicle, there was a clicking sound coming from under the hood, and then the sound stopped. While driving approximately 55 - 60 MPH, a fuel odor was detected inside the cabin of the vehicle. The vehicle was diagnosed by an independent mechanic, who determined that the exhaust manifold bolts had fractured. The bolts and gaskets were replaced. The manufacturer was notified of the failure by phone, and a case was filed. The failure mileage was approximately 125,000.

TIRES, TIRES:MARKINGS, TIRES:SIDEWALL
I purchased four tires for my truck from Firestone, each rated for 60,000 miles. After approximately 30,000 miles, all four tires developed microcracking and visible damage. I suspect the issue may be related to the quality or composition of the materials used. I contacted the Firestone location where I had previously taken my vehicle for maintenance and tire service to have the tires inspected. While an employee was assisting me, I showed him photographs of the tires on the side of the computer counter to start the process to replace them, then manager approached to me rudely and disrespectfully asking me to go to the front, replaying to him : I am showing pictures of my tires asking me to leave the store just for that. Afterward, I had the tires inspected at Costco, where I was advised to replace them as soon as possible because represent a safety issue. For the safety of my family and myself, I replaced the tires for another brand. I subsequently filed a complaint with Firestone’s corporate office, but Firestone has declined to take responsibility for the condition of the tires asking to refund me the money I paid for the tires and a relief for the way I was treated. I am attaching pictures to show the condition of all tires and PDF File an email from Firestone.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
On September 10, 2026, while traveling approximately 60+ mph in the passing lane, my 2018 Chevrolet Silverado 1500 suddenly lost normal acceleration and entered Reduced Engine Power mode. Vehicle speed dropped to approximately 40 mph, and pressing the accelerator would not provide normal power. This created a safety concern while traveling at highway speed. On September 11, OnStar On-Demand Diagnostics documented ECM code P2138 (Accelerator Pedal Position Sensor 1-2 Correlation) and ABS code U0422. The TCM reported no error codes. The check-engine light later turned off, indicating the problem is intermittent. GM Technical Service Bulletin 07-06-04-019F addresses intermittent P2138 with Reduced Engine Power and possible water intrusion/corrosion affecting the accelerator pedal position circuit. After removing the driver’s kick panel, we observed evidence of previous moisture/rust in the area, but the exact cause has not yet been diagnosed. The vehicle is scheduled for diagnosis by a Chevrolet dealer. I am reporting this because the sudden loss of acceleration at highway speed created a safety hazard and to document the incident for potential defect-trend investigation.

ENGINE
I Tried to get a tune up and found out that the Engine need $5000 worth of engine repairs. I have changed the oil and filter every three thousand miles. Those engine are defective and the repair shops are full of the same type of repairs on that type of engine. My engine is a 5.3-liter V8, The engine started to make ticking noises out of nowhere and then it started missing badly. The repair shop informed me it would take 3 weeks before i could get it repaired at the cost of $5000.I did research on the 5.3 liter engine and found out that GM produced a engine that will cost us owners a lot of our heard money for a defect they created, This is so wrong Because i am a senior citizen. I paid over $50,000 for a limon that is just wrong.

STEERING, SUSPENSION, WHEELS
Description of Safety Defect: I purchased this 2018 Chevrolet Silverado 2500HD from Carvana. Within 14 days of vehicle delivery, an authorized, in-network warranty repair facility (Monro) diagnosed a critical safety defect in the steering linkage, identifying failed outer tie rod ends and a failed pitman arm. Carvana’s warranty administrator, SilverRock (Claim C102648992), acknowledged the structural steering failure by approving the pitman arm and idler arm replacement but explicitly denied the required tie rod ends, claiming "no failure." The vehicle has since been released back to me with the failed tie rod ends still installed. On this heavy-duty truck, the steering linkage has now deteriorated to a catastrophic failure point. With the truck parked on the ground, there is severe, excessive manual play allowing the front wheel to be physically shaken left-to-right by hand. The vehicle cannot be aligned, is structurally compromised, and is completely unsafe to operate on public roads due to the imminent risk of a total loss of steering control. Carvana and SilverRock delivered an unsafe vehicle that failed its structural inspection points, and subsequently refused to complete the safety-critical repair required under their mandatory 100-day limited warranty window, forcing a dangerous, heavy-duty vehicle back onto public roads.

ELECTRICAL SYSTEM, STEERING, ENGINE
Intermittent issues seemingly related to power or ground problems. At idle, battery voltage drops down from 14-15v to <= 12v (as indicated on the voltmeter on the dash) while turning the steering wheel. "Service StabiliTrack" message shows up on the screen, and the steering becomes very difficult. Last night this issue happened and the truck completely lost power including interior lights, headlights, radio, accessory power, and the engine even turned completely off. This happened in the middle of the street as I came to a stop in front of my house and was going to reverse into my driveway. Cycling the key was enough to restart the truck and the power came back on. When this first happened to me almost two years ago, I brought the truck in for transmission concerns (resulting in a transmission replacement) to my local dealer, and I explained what had happened and they could not reproduce the concern and said everything checked out fine. I've had strange electrical problems pop up every now and then including this StabiliTrack warning message and a trailer brake warning when I am not even hauling a trailer, but this is a major safety concern. My wife and daughter were in the truck with me when it happened, and if the power ever shut off like this on the freeway, major road, or even off-roading, it would be disasterous.

ELECTRICAL SYSTEM, ENGINE
Several times, while driving, the truck will simply shut down. It will becoime difficult to steer, then the engine will stall, killing the rest of the steering and the breaks as well as the dashboard, radio, etc. This can happen at any speed, low speed especially. I will give you an approximate date below, but there have been several incidents. The truck was looked at by our local mechanice, who could not find a problem and by the dealership electrical specialist who has also been unable to locate a problem.

FUEL/PROPULSION SYSTEM
The high pressure fuel pump failed and sent metal particles throught the fuel system. All fuel components except for the injectors are available. The engine stalled while driving at speed forcing me to stop and call a tow truck on the side of the road. Mileage at failure was 81340. Preston hood Chevrolet diagnosed the HP4 failure and replaced the entire fuel system, noting metal contamination in all areas. The component has not been inspected. The truck had a slight grinding noise when shifting into 4th on throttle. Took it to a firestone and the techs noted its possibly just shifting hard, no issues found. The grinding noises ultimately was the HP4 failing. No warning lamps or other indications of a problem were present prior to the catastrophic failure.

ELECTRICAL SYSTEM
i was driving down the highway, turned on left signal to make left turn. the truck engine died with no warning, could not steer, almost ran into bank. all the dash lights went black, no power at all. the radio starts playing on occasion without being turned on. the clock loses time when it wants to.the blower on the ac comes on and off when it wants to.have had battery, alternator, ignition system checked. all these check out just fine. there were no codes , and absolutely no lights or warnings on dash. our truck was still in the highway lane. luckily the police stopped and assisted by directing and holding up traffic as necessary. i have had similar issues on other occasions but was always more brief and the truck would crank back up right away.

POWER TRAIN
There was premature torque converter failure that’s has taken out the transmission unexpectedly. I was coming from a side street to get onto a main highway and as I left the stop sign the truck stalled upon take off and I was stuck half way on the highway and halfway on the side road. Until it jerked hard back into gear and pulled off. If the torque converter wouldn’t have caught in time then it could have cause a serious accident. The truck only has 95,000 miles and is a 2018 Silverado 1500 LT 4x4 with the 6l80e transmission. I had to park the truck until the following week when I could take it to dealership and they diagnosed it and quoted me for a new transmission and torque converter. Something needs to be done about these transmission as they are a serious safety concern. No police report was made since there was no accident but there definitely could have been.

ELECTRICAL SYSTEM, SERVICE BRAKES, ENGINE
Purchased used 6/12/2026 at 188,882 miles from a franchised Chevrolet dealer. The integrated trailer brake system master fuse and passenger-side turn signal fuse were blown at delivery. When the fuses were replaced, the trailer brake system faulted and the failure disabled the ABS, traction control, and StabiliTrak (electronic stability control). Significant safety concern: with the master fuse blown/open, the vehicle displays NO warning messages of any kind — the safety-system failure is completely masked while trailer braking is inoperative. The warning cascade only appears when a good fuse is installed and the faulted circuit is energized. Separately, at approximately 12 days and ~1,700 miles after purchase, the engine began knocking and set diagnostic trouble codes; a dealer repair order dated 7/6/2026 documents the knocking complaint with no work performed. The vehicle is currently parked as unsafe to drive. No crash, injury, or fire. Reporting so the ABS/ESC failure mode — and particularly its masking behavior when the fuse is open — is on record for this VIN and vehicle line.

The engine lifters and camshaft started to fail at 114,000 miles. I had to have it repaired at a dealership and it cost over $10,000. I had completed all recommended maintenance prior to the failure. 500 miles after that repair was completed, my transmission overheated and completely left me stranded on the side of the road. I had to have it repaired at a dealership which cost $$8,000
