2017 CHEVROLET BOLT EV Complaints

I am reporting a potential steering system safety defect involving my 2017 Chevrolet Bolt EV. The problem began at approximately 22,800 miles. The steering wheel developed a grinding noise, a noticeable catching/binding sensation when turned, and would not return to center normally after a turn. The condition could be felt even while the vehicle was stationary and not running by turning the steering wheel back and forth. While driving, I could feel the steering pull and catch when turning left or right. The problem gradually became worse over about two months. There were no warning lights or dashboard messages. I first tried to have the vehicle inspected by a Chevrolet dealership, but that appointment was canceled. I then took it to Lee Johnson Chevrolet in Kirkland, WA. At 23,661 miles, the dealer test drove the vehicle and documented that they verified my concern. Their diagnosis stated that the steering gear had “internal worn gear damage” and required replacement of the steering gear/rack assembly. The intermediate steering shaft bolt was also involved in the repair. I paid $4,406.56 for the repair which includes a separate $301.24 diagnostic charge. The vehicle was not covered by warranty. The repair appears to have corrected the problem. I am concerned this is a premature manufacturing or component defect rather than normal wear. The vehicle has never been in an accident or collision and had fewer than 24,000 miles when a safety-critical steering component required replacement. The progressive grinding, binding, pulling, and failure to return to center made the steering increasingly unpredictable. I have also found numerous reports from other Chevrolet Bolt owners describing similar steering problems. I believe NHTSA should investigate whether premature steering gear failure in 2017 Chevrolet Bolt EVs is a broader safety defect.

The steering rack on the Chevrolet Bolt EV does not return to center on turns. Over the course of the past 25k miles, my particular model has slowly began to lock up on deep turns. This occurs on sharp rights, lefts, and on both on and off ramps - especially the ones that loop around. The steering rack gets stuck on sharper turns and continuous turns, requiring force to return back to center or to get out of the turn. With hands off the wheel, the vehicle maintains its turn radius and without driver input, would inevitably turn into a barrier, object, or even another vehicle. Issues began around the 80k mark, possibly sooner, and dealer did not fully disclose this occurrence. The steering binding is a safety issue, and if left long enough might fully bind up causing an accident. It reduces my ability to sense road traction conditions and make fine adjustments.

Without any warning, the INFO-TAINMENT COMPUTER SYSTEM on the dashboard (BOLT EV) fails to come on, sometimes lasting up to 5 minutes. This has happened intermittently for the last 8 years and can be problematic. When the computer info-tainment is not on, I cannot control anything on the dashboard. For example: I have no back up camera and cannot see when I back up from my garage. I cannot control the heating/cooling system/ audio/ defroster(which can be dangerous because I cannot see through my front/back windsheild). The system reboots itself afer approx. 5 mins, but in the meantme, driving can be dangerous.

COMPONENT: Electric power steering (EPS) steering gear / rack and pinion assembly. WHAT HAPPENED: The steering gear binds internally. After a turn the wheel does not return to center and must be forced back to straight; steering feel is stiff and clunky. On at least one occasion the wheel felt stuck in place partway through a turn and I had to fight it to finish the maneuver. I nearly lost control of the vehicle. Exact date, location and speed of that incident: UNKNOWN. The condition is chronic and has worsened over time. I own two Bolt EVs (2017's); both have this defect and I am filing a separate complaint for each. Mileage on this vehicle: approx 96,000 but it's been bad since 80,000 (at the very least). SAFETY RISK: Binding steering requires manual correction after every turn, increasing risk of overcorrection, unintended lane departure and delayed emergency response. Worst at intersections, on/off ramps and parking lots. The driver cannot anticipate when the wheel will stick. WARNING LAMPS / PRIOR SYMPTOMS: [No warning lamps, messages or codes appeared] Earliest symptom: [stiff or notchy steering]. First noticed [right away when I bought the car used]. CONFIRMED BY DEALER OR SHOP: [not yet presented] INSPECTED BY MANUFACTURER, POLICE OR INSURANCE: No. AVAILABLE FOR INSPECTION: Yes — vehicle and original steering gear assembly. This failure is widely reported across Bolt EV and EUV model years. GM service information contains a diagnostic procedure for poor return of the steering wheel, indicating the manufacturer is aware of it. No safety recall has been issued, and dealer repair runs $2,500-$3,500 because the subframe must be lowered to reach the rack. Videos of the repair are available online, which also include plenty of discussion about the symptoms and dangers: [XXX] and [XXX] I request that NHTSA open an investigation into the Bolt EV/EUV steering gear as this should 100% be a priority safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am experiencing a commonly reported issue with the steering rack binding and failing to self-center after a turn. Turning the steering wheel left and right has become increasingly more stiff over time. Unreliable steering, especially during turns could potentially lead to an accident/collision.

Steering is binding, does not return to center when turning, it has play in the steering, and rattles and shakes when driving in the highway. Dealer said it needs a steering shaft replacement. The car has been doing this since it had less than 50k miles. There were no warning lamps or messages. Since this is steering, it is dangerous and puts others at risk. The steering binding is a safety issue, and if left along long enough it might fully bind up causing an accident, and also reduces my ability to sense road traction conditions and make fine adjustments; I feel a recall is warranted because of the serious nature of this problem.

Infotainment unit did not come on. Connection error displayed. Backup camera did not display when in reverse.

Infotainment unit did not boot up. Had a communications error. No rear back up camera view when put car in to reverse.

Component or system that failed/malfunctioned: The Electric Power Steering (EPS) Gear / Steering Rack Assembly. The component has not yet been removed from the vehicle and is available for physical inspection upon request. How safety is put at risk: When navigating low-speed turns or accelerating from a stop where the steering wheel is rotated to approximately 45 degrees, the steering gear mechanically binds and catches. The wheel completely fails to self-center or return to a straight position on its own. The driver must apply sudden, manual physical force to yank the wheel back to center. This creates an immediate loss-of-control and lane-departure hazard during low-speed maneuvers. Because this is a progressive mechanical wear issue, there is a severe risk of a total steering lockup at higher highway speeds. Confirmation by dealer/independent center & manufacturer inspection: The vehicle has not yet been inspected by a dealer, independent service center, or the manufacturer due to the high out-of-pocket cost of the repair. The owner is operating the vehicle with extreme caution while awaiting a formal safety recall regarding this documented steering gear defect. Warning lamps, messages, or prior symptoms: No electronic dashboard warning lights or error messages have illuminated. The primary prior symptom was a subtle, rotational scraping/friction noise heard coming from the front driver-side wheel well when passing roadside walls or barriers, indicating ongoing mechanical friction within the steering assembly. The 45-degree steering binding first appeared several months ago and has progressively worsened.

While slowing to a stop, the vehicle suddenly experienced multiple (3–4) violent jerks. The vehicle fought against my firm brake pedal application, overpowered the brakes, and accelerated uncontrollably, resulting in a crash. During the impact: • The driver frontal airbag and pretensioners deployed. • The driver seatbelt unlatched mid-impact and then locked/retracted in a way that prevented it from latching again, even while I was sitting in the driver’s seat post-crash. I have only been provided with the limited Airbag Control Module (SDM) data, which shows the brake switch as “Off” and low accelerator pedal readings. This data does not match the events I experienced. I have formally requested full downloads from all other modules (Powertrain/PCM, ABS/EBCM, BCM, etc.) from both the insurance company (ESIS) and GM, but they have only provided the single SDM report. This appears to be a sudden unintended acceleration event combined with a brake override failure and seatbelt restraint system malfunction.
