Among the 6 model years of Chevrolet HHR in our records for brakes problems, this one ranks #3 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

The failure pattern owners describe
The dominant complaint across these 31 reports is front brake rotor warping that occurs at remarkably low mileage. Owners first notice violent vibration and shaking in the steering wheel and brake pedal when braking, starting as early as 2,000 miles and widespread by 10,000 to 35,000 miles. The problem worsens downhill and at higher speeds, and is more severe in hot weather. Dealerships respond by resurfacing (turning) the rotors, which provides temporary relief—typically 6,000 to 10,000 miles—before the symptom returns. Several owners describe rotor service cycles repeating three, four, or even five times before resignation sets in.
Multiple service managers told owners the OEM rotors are defective—one stated the steel is "too soft," another said rotors were "made as cheaply as possible." No recalls exist. One owner replaced his rotors with aftermarket Canadian-made units at out-of-pocket cost. Two critical failures stand out: one owner's brake pedal went to the floor with zero response, and another experienced brake lockup during rain that resulted in a collision. The vast majority of these reports come from owners who purchased the vehicle new, making this a manufacturing or design issue affecting the model across multiple production runs.

Failure modes owners describe
Brake rotor warping and premature wear
Front brake rotors warp prematurely, causing vibration and pulsation during braking. Multiple owners report rotors requiring resurfacing or replacement at very low mileage (2,000–28,000 miles). Several owners experienced repeat failures after rotor service. The issue occurs across a wide range of speeds and is worse during downhill braking and in hot weather.
When: 2,000–80,000 miles; most complaints occur before 35,000 miles
Symptoms owners cite: Violent shaking and vibration in steering wheel and front end during braking; Pulsation in brake pedal; Shimmying and shaking of the whole car when brakes applied; Worse at higher speeds and when braking downhill; Worse in hot weather conditions
Repairs/costs cited: Dealer resurfaced or turned rotors multiple times; several owners report repeat failures within 6,000–10,000 miles after service. One owner replaced rotors with aftermarket Canadian-made set for $282.19 (parts and labor). Another owner replaced front brake pads and rotors; problem persisted.
Recalls/TSBs owners mention: No recalls identified by owners. Service manager at one dealership acknowledged the problem as common in HHRs and stated the steel used for OEM rotors is too soft. Another service manager stated brakes were made as cheaply as possible. No warranty repairs or service bulletins mentioned by owners.
Brake pedal vibration and steering wheel shake during braking
When braking is applied, the brake pedal vibrates and the steering wheel shakes noticeably. Owners describe the sensation as uncontrollable and scary, especially downhill. The issue persists even after rotor service or replacement.
When: 9,000–42,000 miles; some reports at 5,000 miles
Symptoms owners cite: Steering wheel vibration and shaking when brakes applied; Brake pedal pulsation; Front end shakes and shimmies abnormally; Described as 'violent' shaking at higher speeds; Occurs at speeds as low as 15–20 mph
Repairs/costs cited: Rotors turned multiple times with temporary relief; one owner had front rotors resurfaced twice at purchase and replaced on two additional visits without permanent resolution. Another owner had brake pads and rear brake pads dusted and outer tie rods replaced; problem recurred.
Recalls/TSBs owners mention: Manufacturer made aware in at least one case; no response documented. One dealership stated they could not do anything about the problem without charging for repairs.
Brake failure or loss of braking effectiveness
In two separate complaints, owners experienced critical brake failures: one where the brake pedal went to the floor with no braking response, and another where brakes locked during rainy conditions and the vehicle did not stop, resulting in a rear-end collision at 37 mph.
When: 71,000 miles (collision); timing not specified for pedal failure
Symptoms owners cite: Brake pedal went to floor; No braking response; Brakes locked during rainy conditions; Vehicle failed to stop
Repairs/costs cited: One vehicle was destroyed in collision and towed; cause of failure not determined. No repair details provided for the other incident.
Recalls/TSBs owners mention: Manufacturer notified in collision case; no response documented.
ABS system fault
One owner reported the brake fluid warning light illuminated after starting the vehicle. OnStar diagnostic revealed an ABS system problem.
When: Timing not specified
Symptoms owners cite: Brake fluid warning light illumination; ABS system fault detected
Repairs/costs cited: No repair details provided.
