We went to an appointment and when we got back in the car, a message was on the screen. It said that the brake system has failed and we could only drive 43 mph maximum! The engine light was on and we could not accelerate beyond 43 mph. This is extremely dangerous when driving on a highway! We drove home on the interstate going 43 mph in a 70 mph zone! We had small children in the car and almost got into a few accidents due to other aggressive drivers. We then called local dealers who said that they were too busy to take our truck for weeks! They also said that our truck was not covered under warranty. So we took it to a local body shop. They fixed it for just above $500. It worked for a week and broke again, then they fixed it again for free. The brake failure 43 mph light came on for the 3rd time. We took it Garber and they fixed it after 2 weeks and charged us a fortune. Invoice attached. A few weeks later the same light came back on. Garber then took another 2 weeks to fix it! I’m writing here as I’ve seen other silverados recalled for the same issue but not my exact truck (year). It’s obviously faulty software and it should not be the customers responsibility to fix. Especially with a vehicle under 20k miles! There is absolutely no way that we will ever buy a GM again but the important part here is that other people are not put into a dangerous situation like we were. Besides dealing with this issue for well over a month - the important part is safety. I can’t understand how these trucks have the same problems but only certain VINs qualify for a recall. Please consider our truck as part of the overall recall for this issue. It’s unethical to pick and choose only certain VINs!
2020 Chevrolet Silverado 1500 driver assistance complaints
Page 2 of 2: complaints 11 to 27 of 27, newest first, as owners wrote them.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the contact experienced resistance while using the gear shift lever to drive and there was a hesitation while shifting gear. Additionally, while in reverse on several occasions, the back over prevention screen went black and failed to operate as intended. The vehicle was taken to a dealer but was not yet diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 20,000.
Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that i could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given i could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As i was getting on the highway, the truck started to jerk like it wanted to stop as i was speeding up, i was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service ESC" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day i scheduled an appointment with a mechanic in town who checked it and said i would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9K.I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0P50D and P0304.He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60K miles and I have 80K now.
Started to notice water marks on the driver and passenger side rear window. According to online forms it is a common problem with 2019 and 2020 silverados with a sliding rear window. The dealer claimed it wasn't a safety issue, which I argued it was due to the mold. Chevy knew about the manufacturing problem before they even sold me the vehicle and did nothing to fix it
Brake system light failure. Some system lights came on. I had no breaks car didn’t stop fast enough before hitting a pole
The component that recently failed on my 2020 Chevy Silverado is the side detection/blind spot warning. It no longer works and upon startup of my vehicle the notification on my dash shows “side detection temporarily unavailable”. This problem started 3 weeks ago. After doing research online, it seems that there is a common issue in Chevrolet vehicles with water getting into the rear sensors in the bumper. There were also several new model Silverado’s with the same issue. As you can see, this is a safety issue as this feature all of a sudden stopped working on my truck so I no longer get warned if someone is in my blind pit while I am driving. I contacted my local Chevrolet dealership and they stated that because my vehicle is over 30,000 miles (36,000), I am no longer covered under warranty to have this issue repaired. My vehicle is scheduled to be looked at by the dealership on 6/27/22.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 40 MPH, the vehicle suddenly started to shake and misfire. The contact stated that the ESC warning and service parking brake warning lights were illuminated. The contact coasted to the side of the road and restarted the vehicle. The contact took the vehicle to the dealer who diagnosed that the electronic stability control module had performed an automatic reset as designed. After the reset, the misfire occurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 7,700.
My truck is only a year old and one morning I was reversing out of driveway and back up camera stopped working
In may I purchases a 2020 silverado. On december 05th, 2020. I was driving on the interstate heading home from my son's football game . The "service brake system" message displayed on the vehicle's dashboard. Braking became sluggish and stiff. I initial thought the brake fluid had had leaked out. The vehicle maintained power to all other systems. Once home I checked the engine bay and brake calibers and found them to be intact. At this time the vehicle has 12,400 miles. After a initial assessment, was informed that it was determined to be a "computer glitch" that was effecting the transmission and brake sensors. The brake module was replaced and transmission "software" was updated. This was completed on december 09th, 2020. Upon completion the techs conducting a "drive test", at which time the warning appeared again. My vehicle remains at the service department, while they "troubleshoot" the problem. Due to the vague responses being provided by the dealership service staff and the lack of an estimated time line for the completion of the repairs. I believe there is a much larger issue that they don't want to reveal.
1st occurrence, 9840 miles- slowing to stop sign, about 10mph, truck jumped violently, felt like I was rear-ended. Service parking brake, service ESC, traction control off messages and cel on. Stuck in gear. Restarted truck, resumed normal operation but cel remained. 2nd occurrence, 9865 miles - 65mph on highway going around curve, truck jumped violently causing rear end to break free slightly, though I kept control. Transmission now several gears lower and stuck there, turning 2400 RPM at 65mph. Same three warning messages and cel. Tried manual transmission mode, but it displayed no gear indication, and the +/- buttons did nothing. Pulled off highway, restarted, all messages went away, cel remained. Truck resumed normal operation. 3rd occurrence, 9905 miles (on the way to the dealer) - I was stopped at traffic light, first in a string of cars. Light turned green, I started to accelerate, just into the intersection, truck jumped violently, same warning messages, still had the cel from the last time. Truck was now stuck in a higher gear, could barely get through intersection. Vehicle behind me narrowly missed rear-ending me, and others were blowing horns as I limped to the far side of intersection. This is a massive safety concern. If any of the above scenarios had occurred on snowy/icy roads, I could have injured or killed someone, including myself and/or my [xxx] year-old. Dealer replaced TCM, but is still noting "loss of communication" codes being generated. A chevy engineer has requested them to investigate the wire harness for damage in a particular location, suggesting chevy knows of a manufacturing issue. If that's so, and chevy hasn't issued a recall - or even a tsb - then this poses a strong case for negligence on their part. Are they waiting for someone to get injured or die before acting on this? I've now been without the truck for 10 days. Parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b
I went in the store this afternoon, when I returned to my truck and started it up I had a service power steering drive with care warning as well as service ESC. I shut the truck off, waited a few minutes and restarted the truck, the warning was still there so I called the dealer and they sent out a service tech and service mgr, they couldn't figure it out and had it towed to back to the dealer the truck only has 1400 miles on it
Brake system failure on 2020 chevrolet silverado 1500. Multiple dash warnings notifying of brake failure, ESC failure, and service brake system warning
Traction control system disengages with while vehicle is in motion and multiple warning lights are activated. (tcs, check engine light, and "engine operating at reduced power" while vehicle is in motion. This is a new vehicle and incident occurred at less than 300 miles. This seems to occur while braking: first while driving in traffic (traveling at <25mph), then when slowing on approach to highway off ramp (traveling at <45mph).
This issue has happened multiple times, in the city, highway, and definitely while I was in motion. This has almost caused me to rear end another driver. I get a ABS warning and my speed is limited to 62mph. My brakes are harder to press on and doesn't slow down the truck normally. I get a ABS sign, traction control sign, and a check engine sign. The truck is almost brand new with one previous owner, and only 15k miles. This issue needs to be resolved, this is unacceptable. A truck is a lethal machine and if I'm not able to stop the truck how it should be stopped, I could possibly hurt or kill someone.
It happened after driving on the interstate, we pulled into a gas station and when we got back on the road I found the list of warnings and I lost most all braking and power steering and had a dash full of lights telling me all sorts of warnings. I pulled over on the interstate on-ramp and turned it off and back on and the problem continued. 'service parking brake' 'traction control off' 'engine power is reduced' 'brake system failure" 'service ESC' 'service trailer brake system' 'steering assist is reduced drive with care' "speed limited to 43 MPH"
While driving service ESC message and system brake failure message illuminated on center cluster display, attempted to apply the the brakes and pedal went to the floor almost rolled into a busy to lane road in the city. Received an onstar message immediately as well, put truck into park and shut it off and removed the key and opened the driver door, then restarted truck previous messages were gone but check engine light was on. Two days later at the dealership the check engine light was off.
I was driving down the road, gave it gas to go around a vehicle and it felt like the vehicle shut down. Esc caution, check engine light, and brake warning/caution all illuminated. Vehicle began to slow down drastically and if I hadn't gotten off the road quickly I would have been hit. If I had been turning into traffic from a stop and that happened I would have been hit. Pulled the vehicle over, turned it completely off, removed the key, restarted the vehicle and everything went away except the check engine light. Headed to the dealership and again I gave it some gas and it did it again. Pulled over, turned off/on and same results, everything cleared but check engine light. If this were to happen on the interstate this could cause a major incident. I was on a city street on both occasions. I had to nurse the gas pedal returning to the dealership which was about 7 miles from the initial incident. The vehicle is a 2020 chevy silverado 1500 with the 2.7l turbo engine.
