On 2 difference occasions over the past 3 weeks, my car has malfunctioned while I was driving. There were no warning lamps, messages or other symptoms prior to this. All of the lights on the dash came on, the power steering went out, the brakes would not work properly and I could not accelerate. I had my child in the car and we narrowly avoided being hit by other cars both times since I couldn't control the vehicle. I couldn't even power the car down initially but was finally able to turn it off and back on and function resumed after several cycles. I was driving on electric battery that time. The first time, the dealership stated that the following codes were present: P1e00 and P16BA. They replaced the g1 a/c compressor. The incident occurred again a week later when I was driving on gas. At that time, there were history U codes present for every module, per the technician but no current codes to identify the problem. The problem has not been able to be reproduced since. The 2nd incident occurred out of state and my car was towed back to Texas where I live. The dealership there refused to investigate the incidents since they couldn't reproduce them and there were no current codes showing. It has subsequently been towed to a different dealership where they are still trying to identify the issue. I contacted General Motors and was contacted by a rep who escalated the issue. The next rep escalated it again greater than 48 hours ago and I have received no further contact from GM. The 2nd rep informed me that since the dealership that it was originally at says that it's safe to drive that they can't do anything. This car is NOT safe to drive.
2017 Chevrolet Volt brakes complaints
Page 2 of 2: complaints 11 to 27 of 27, newest first, as owners wrote them.
When I put the car in park the vehicle tells me I need to shift to park even though it is shift to park. Vehicle will not shut down and drain itself.
This vehicle has a “Shift to Park” issue which is well established all over the internet. I’m afraid to walk away from the vehicle when that message pops up. Seems to be something that could injure/kill someone if the car cannot be left in park safely. This has been an ongoing/intermittent issue for months. The date stated below only represents today’s date of report.
It is an ongoing issue and that happens intermittently. When arriving to a stop (at times) the car still advances forward about a foot, even when the brake pedal is being used as far as it can. Also the vehicle claims to be losing propulsion, often, and seems strained when operating when the message appears.
I exited the vehicle and it rolled backward. I was struck by the door and crushed between the car and an adjacent brick wall.
We own two 2017 chevy volts. Both have two issues: 1) often cruise control does always stay engaged due to brake pedal slipping to a very slight depressed position. 2) shift-to-park- cars will not properly go into park sometimes and thus cannot be turned off. These two issues are clearly manufacturer defects as both cars were bought new and within a month of each other. I will enter this for my other VIN number as well. These have been ongoing issues that we are having to spend money to correct and there are many reports of these being issues, yet there is no recall. We purchased both cars brand new within a month of each other. Both issues have been ongoing and have occured more than once.
Purchased a 2107 volt premier with 40k miles in july 2020. My wife was driving the car and it lost power on the freeway with a "shift to park" warning and check engine light. She was able to glide over to the shoulder and I came to rescue her. After repeated on off cycles I got the car to move a couple of miles with several "jerking" motions while driving then it died again and I lost power braking (went to manual only). This time I was unable to "re-boot it" and had onstar have it towed to a local chevy dealer who has a "certified EV specialist"
While driving on city streets and highways, the adaptive cruise control will not engage 25% of the time and will disengage without notice. "adaptive cruise control will appear in dic. However, this creates a safety hazard as you never know if the car will automatically slow down. I have filed case # 9-5379585813 with chevrolet and been to four dealers and they refuse to fix the problem. They no longer return my calls. I am afraid to use the cruise control.
After diagnosing an audible tick/click sound that occurs whether the car is powered on or off but stops momentarily when the brake pedal is applied, I was told the electric brake booster is bad and must be replaced. But gm has no parts available. I was told to drive the car and if the part fails completely, I will have no brakes at all. It has been over 3 weeks and there is no eta on parts.
When approaching a stop and applying the brake pedal, the brake pedal suddenly sinks and car loses traction and the car suddenly feels like it starts to slide. After releasing and then reapplying the brakes, the returns to normal.
Adaptive cruise control unavailable randomly occurs while driving using adaptive cruise control. Presents a large danger of hitting other vehicles if the adaptive cruise control is used to come to a complete stop as it will randomly disengage while coming to a stop. Cruise control only works 4/10 times attempted and was "fixed" by the dealer with less than 500 miles on the odometer. However the problem recurred within a day. Looked it up in forums and it is not an uncommon problem. Holding foot under the brake pedal allows cruise control to work but is more dangerous than randomly cutting off. No one in volt forum has gotten a complete fix to date. When they do I will be getting mine repaired armed with the correct information. But it is dangerous.
While approaching a red light at 35mph on a smooth road when I pressed my brake pedal nothing happened for nearly a second then the brakes worked as usual. Luckily no one was in front of me or I could of easily been in a crash. The volt has a brake-by-wire system with regenerative braking. I feel that either the regenerative braking failed and the computer took a long time to revert to the friction brakes or the brake module temporary failed and neither regen or friction brakes were available. I've driven a first year leaf where sometimes there is a slight delay when switching to friction brakes in certain situations, and this event was much much worse than that. Road and weather conditions were perfect that day.
The brake pedal and gas pedal both modulate pressure needed to either accelerate or brake. The brake pedal will change pressure needed to brake suddenly, causing you to apply much more force to brake pedal, which is unexpected and dangerous. For example, when driving at highway speed, a car in front of you stops, and you apply brakes. Traffic clears and you release brakes, but then car in front stops again and requires you to brake again suddenly. This time the brake pedal will require more pressure and pedal travel is significantly more. This is unsafe and needs to be changed.
While slowing down approaching a red light with the gear in l (regenerative braking), the car was in electric mode and traveling at a low speed (under 10mph and likely less than 5mph) when the passenger side front tire went into a large but shallow pot hole at which time the car felt like it accelerated (at the very least deceleration ended). My foot was already on the brake pedal (not sure if I was pressing it); however, I immediately mashed the brake pedal down as far as it would go. At first this did not seem to have any effect. After a moment, though, it finally kicked in and the car stopped immediately. I do not believe I hit the car in front of me (which was completely stopped). However, that driver wasn't sure if I did and asked for my information (there was no paint transfer or any marks on my car--there was a mark on the other vehicle which I believe was already there and the other driver wasn't sure and wanted to talk to her husband about it). Note in the later section that asks "was there a crash?" I am marking no as I do not believe there was a collision nor is there any physical evidence on my car of a collision. However, the other driver may dispute that.
Vehicle brakes fail to fully engage intermittently. When slowing down on multiple separate occasions, the brakes work initially, then, the car feels like it's sliding on ice (dry summer roads) then the brakes engage again. The brake peddle generally feels normal at first, then goes soft and sinks. I've taken the vehicle to the dealership on multiple occasions who've stated there's nothing they can do. This is a serious safety concern to just send someone on their way with. I've also been working with general motors. While working with gm, they recommended I take the vehicle to a different dealership for a second opinion. The new dealership found error codes outlining the traction control module is malfunctioning and electrical ground issues exist.
This electric car has regenerative braking. Besides being in the regular braking, there is a pure regenerative braking paddle on the steering wheel. But when you use this brake, the brake lights to not turn on. This is a major hazard as I use this brake all the time and cars behind me do not know I am braking and have almost rear ended me. Chevy dealer says that is the way it is designed and is functioning perfectly. Why has this been approved to design a braking system without any warning lights? What can be done about this?
I was approaching a sudden red light and applied my brakes hard but not too hard (I did not suddenly slam the brakes). The brakes applied as expected at first but the brakes let up some and my vehicle failed to decelerate for about half a second before the brakes applied again and decelerated to a stop. I was not able to depress the pedal further when it was clear that the brakes were not decelerating.
