What the Silverado MD brake pressure switch recall covers
General Motors issued a recall for certain Silverado MD (mid-size) trucks because the brake pressure switch can fail, which means your brake warning light may not turn on when it should. The switch sits in your brake system and tells your dashboard when brake fluid pressure drops — a sign that something is wrong. If the switch fails, you lose that warning, so a brake problem could develop without you knowing.
This recall affects specific model years and production dates. The exact years and VIN ranges depend on when your truck was built. You can find out whether your truck is included by entering your Vehicle Identification Number (VIN) on the National Highway Traffic Safety Administration (NHTSA) website at safercar.gov, or by contacting a Chevrolet dealer with your VIN.
The recall does not mean your brakes will fail. It means the warning system that alerts you to a problem may not work. Your actual brake function is separate from this switch.
Key Takeaways
- The brake pressure switch can fail silently, which means your brake warning light may not illuminate if brake fluid pressure drops.
- You can check whether your specific truck is covered by entering your VIN on safercar.gov or calling a Chevrolet dealer.
- GM will replace the brake pressure switch at no cost to you at any authorized Chevrolet dealership.
- The repair typically takes less than an hour, though appointment availability varies by location.
- You should have the repair done as soon as possible, because a failed switch leaves you without an early warning of brake problems.
How to check if your truck is affected
Start by locating your Vehicle Identification Number (VIN). You can find it on the driver's side of your dashboard (visible through the windshield), on your vehicle registration, or on your insurance card. The VIN is 17 characters long and includes both letters and numbers.
Go to safercar.gov and click "Check for Recalls." Enter your VIN in the search box. The site will show you every active recall for your truck, including this one if your vehicle is covered. You will see the recall number, the part affected, and a brief description of the issue.
If you prefer not to search online, call any Chevrolet dealership and give them your VIN over the phone. They can tell you when ready whether your truck is included in this recall and can schedule a repair appointment at the same time.
What happens during the repair
A Chevrolet technician will replace your brake pressure switch with a new one. The switch is a small component located on or near your brake master cylinder, which is the part that pressurizes your brake fluid when you press the pedal.
The repair is straightforward and usually takes 30 minutes to an hour. The technician does not need to bleed your brake system or do any major work — they remove the old switch and install the new one. You will not need to leave your truck overnight in most cases.
After the repair, your brake warning light will work as designed. If brake fluid pressure ever drops in the future, the light will turn on and alert you to have your brakes inspected.
Where to get the repair done
Any authorized Chevrolet dealership can perform this recall repair. You do not have to go to the dealership where you bought your truck. Search for nearby Chevrolet dealers on GM's website or use a search engine to find one in your area.
Call ahead and mention the recall by name or number (you can reference it from safercar.gov). This helps the dealership schedule the right amount of time and have the part on hand. Many dealerships can fit you in within a week or two, though wait times vary by location and season.
The repair is free under the recall. You will not pay for the part, labor, or diagnostic work. If a dealership tries to charge you, contact GM directly or report it to NHTSA.
What to do if you have already paid for this repair
If you had this brake pressure switch replaced before the recall was issued, you may be able to request reimbursement from General Motors. Contact the dealership where you had the work done and ask them to submit a reimbursement request to GM on your behalf. You will need your receipt and proof of the repair date.
Alternatively, you can contact GM's customer service line directly. Have your VIN, the date of the repair, and your receipt ready. GM has a process for reimbursing owners who paid out of pocket for recall repairs before the recall was officially announced.
Why this switch matters for your safety
Your brake warning light is one of the first signs that something is wrong with your braking system. Common problems it catches include low brake fluid (often caused by a leak), worn brake pads, or a failing brake master cylinder. Without this warning, you might not notice a developing problem until your brakes feel soft or unresponsive.
A failed brake pressure switch does not cause brake failure on its own. Your brakes will still work normally. The risk is that you will not know if a separate brake problem is developing. That is why GM issued this recall — to restore your ability to see the warning light.
If you notice your brake warning light is already on, or if your brakes feel soft or spongy, do not wait for an appointment. Have a technician inspect your brakes when ready, whether or not your truck is part of this recall.
What to expect after the repair is complete
Once the new switch is installed, your brake warning light will function normally. You should not see any change in how your brakes feel or perform — the switch is purely a monitoring device, not part of the actual braking mechanism.
Keep your repair receipt for your records. If you ever sell the truck, the receipt shows the new owner that this recall has been addressed. Some buyers specifically ask whether recall repairs have been completed.
If your brake warning light comes on after the repair, it means your brake system has a genuine problem that needs attention. Do not ignore it. Have your brakes inspected by a technician as soon as possible.
Frequently Asked Questions
Will my brakes stop working if the switch fails?
No. The brake pressure switch only monitors your brake system and sends a signal to your dashboard. Your actual brakes will continue to work normally. The risk is that you will not receive a warning if a separate brake problem develops.
Can I drive my truck while waiting for the recall repair?
Yes. A failed switch does not affect your braking ability. However, you should schedule the repair soon so you have the warning light working again. If you notice any actual brake problems before your appointment, have them checked when ready.
What if my dealership says they do not have the part in stock?
Ask them to order it and schedule your appointment for when it arrives. Most dealerships can get the part within a few days. If you need the repair urgently, call other nearby Chevrolet dealers to see if any have it in stock.
Does this recall affect my truck's warranty?
No. Recall repairs do not affect your existing warranty. The repair itself is covered by the recall, and it does not change your coverage for other components.
What if I ignore this recall?
Your truck will continue to operate, but you will lose the ability to see your brake warning light. If a brake problem develops, you might not know about it until your brakes feel wrong or fail. Having the switch replaced restores this important safety feature.
