The contact owns a 2018 Chevrolet Bolt EV.

Dear Sir/ Madam, I want to report to you the serious problem I have had with my Chevy Bolt EV ( 2018 VIN [redacted]) In the month of November 2020, after a full charge of my EV Bolt, the mileage on the dashboard kept fluctuating when my husband and I were driving from Santa Cruz to Berkeley. I had to charge it again after 70 miles in Berkeley. On our way back the mileage showed almost zero. I got so anxious that I had to stop the car and move it from Highway 101 South bound to Santa Cruz and get it recharged in San Jose. Second, on three separate occasions, the speed limit on the dashboard also kept fluctuating. Since this model was recalled we took our car to a Chevy dealer in Watsonville and got it repaired. We had to leave the car at the dealer for two weeks since the dealer was getting appropriate parts from Michigan to fix the car. …
I own a 2018 Chevy Bolt that is part of the battery recall for possible fires started in the powertrain battery. I have been through both GM recommended appointments at my local Chevy dealer to have the software patches installed and the battery inspected for nominal voltage. While my car's battery passed the voltage inspection this week, there were 2 new fires reported to GM resulting in new recommendations on July 14 to park outside and not charge over night. The real issue here is GM not providing enough information to the owners of Bolts in this recall. Questions such as: What kind of charger was used (110, 220, CCS)? If after market chargers were used before a fire, what brands, what commonality amongst the group of Bolts that have caught fire? What is the minimum battery remaining on the cars that charged before a fire? …
My vehicle is being affected by 2 recalls for a battery that might melt or burn. The vehicle is also experiencing issues with the infotainment system that is malfunctioning/restarting/shutting down while driving. This is extremely distracting and dangerous and causes the vehicle speed area to fade out as the system restarts. Our family is severely limited by the charge limit, minimum miles, or by having to park it outside and not charge it overnight. We live in an fire brush area and are very stressed about having the vehicle potentially catch on fire and burn down our neighborhood. I tried to trade in the vehicle so that we could move on and they won't accept the car with an open warranty recall. The carfax information literally states that the remedy is NOT YET AVAILABLE. How can we move on and what do we do with our original investment of over $48k? …
The battery in this vehicle was replaced pursuant to the current recall at the Morehart Murphy dealership in Durango, CO about two(2) months ago. On approximately June 5, 2022, the car began showing a "Propulsion Power Is Reduced" warning, despite the fact that the battery was approximately 3/4 fully charged and showing a range of 248 miles. We made arrangements to take the car into the dealership on June 9, 2022. Once the car was at the dealership, the EV technician reported that the dealership had just received a bulletin from GM about this problem on that same day, that the problem was with the replaced battery, that GM engineers were working on the problem, that the car was not safe to drive, and that the car would have to be left with the dealership until a solution was found. We have heard nothing from the dealership since that time. …
The radio antenna/receiver/reception in my 2018 Chevy Bolt is very poor. There are many areas I receive almost no radio stations, or stations are extremely fuzzy. The reception is getting worse over time. In searching for a solution to this, I have found that there are many accounts, complaints, and forums related to this issue in all model years of this vehicle. The greater community has not found a viable solution outside of buying a separate radio and hooking it up to the auxiliary input. Many others have brought their vehicle to get inspected repaired and told by the dealers that everything is functioning as it should. The quality and operation of this part pales in comparison to all other vehicles and devices I, and others as they describe, have owned. Understanding this is not a "life and death" safety concern, I hope that this issue can be addressed. …
Vehicle arrived with windshield chip, transport company provided proof happened before transport. Brake failure on first use after delivery. Reduced-propulsion warning triggered. Both passenger-side door locks failed. Center-console power and data failed (replacements pending). Rear and passenger-side cameras blurry (replacements pending). GM manufacturer buyback vehicle. Safety defect occurred immediately after delivery. Vehicle down more than 50 days. Dealer delayed title paperwork to Tennessee for 44 days and delayed delivering finance contract/payment instructions to buyers for 50 days. GM Financial issued late notices before contract was delivered. Dealer has not responded to reimbursement deadline. Safety and delivery failures created unsafe condition and administrative harm.
In March 2021, I drove my Bolt in very cold weather, and parked the Bolt in my garage with only 7 miles range remaining. I did not plug in the Bolt to charge until 24 hrs later and found out the Bolt would not charge. The Bolt was towed to a local Chevy dealer for service. The dealer found two parts had failed. 1) Drive Motor Battery Coolant Heater, and 2) High Voltage Battery Control Wiring Junction Box. According to the dealer Part 1 was not warrantied, and Part 2 was warrantied. Here's my problem. Part 1 was replaced first but that did not fix the problem. Only after Part 1 was replaced did the dealer find Part 2 had failed. Obviously these two Parts are interdependent. Part 2 caused Part 1 to fail, therefore Part 1 should be covered by Part 2 warranty.
I own a 2018 Chevy Bolt and GM has issues 3 different recalls on the battery due to risk of combustion. First was a software fix to reduced charge capacity, second was a supposed to be a permanent fix to resolve the issue, and finally GM has issues a 3rd recall where they state they will replace failing modules. With each recall the requirements on the owner to keep the battery from combusting have become more and more strict. Effectively, I only have about 140 miles of battery charge out of 230 because they suggest not charging past 90% and not going below 70 miles remaining. Also I cannot charge my car indoors OR unattended. At this point I feel unsafe having this car near my home or family because of risk of combustion.
