2001 Chevrolet Suburban Problems

What owners report

Owners of this 2001 Suburban most often describe brake trouble: either rusted-through metal brake lines that leak and let the pedal sink, or the anti-lock system engaging at low speed on dry pavement and lengthening stops. Fuel pump failures that cause stalling or a no-start are the second recurring theme, and several owners mention the rear parking brake no longer holding. Reports span a wide mileage range, from under 30,000 to well past 150,000 miles, and many describe the trouble appearing gradually and getting worse.

   Brakes

   ABS engages at low speed, longer stopping distance

   • 72 complaints (16%)
   • median 70,000 mi at 4.9 yrs old (61 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $804 (median of 14 quotes)
   • filed 2001–2024

   Complaints describe the anti-lock brakes pulsing or kicking in while braking gently at low speeds, sometimes with a buzzing noise, and the vehicle taking longer to stop or creeping forward. Some owners link it to corroded wheel hubs or sensors, and several say a dealer found no fault at first or replaced a hub without recall coverage. Others report the ABS module failing, with warning lights that come and go. Reported from around 40,000 miles upward, often noticed in spring or after winter road exposure.

   What to check: Ask whether the ABS recall work for corroded front wheel speed sensors was performed for this vehicle, and test-stop on dry pavement at low speed to see if the pedal pulses unexpectedly.

   “While slowing to a stop, the ABS brakes on my 2001 Chevrolet Suburban kick in, rendering the brakes ineffective. It started in the spring (wi) so I was unsure as to whether or not it was road conditions, however after the 2nd occurrence on what was a dry road, I took the car in. Brakes were recently redone, but the shop cannot find anything wrong. Still occurring, and yesterday I almost rear-ended someone due to the gap in brake effectiveness. …”

   NHTSA complaint #10325135, filed 2010-04, 156,000 miles

   “My ABS and brake system lights turn on and off simultaneously and intermittenly, sometimes staying on for the duration of the trip and other times never coming on at all. I have had the brakes checked and replaced, however this did not fix the problem. I'm getting real tired of my 2001 chevy Suburban having problems that are more related to sensors then actual mechanical problems. Often the fixes for these problems are costly and of course, they all occur after the warranty. …”

   Brakes

   Parking brake will not hold the vehicle

   • 41 complaints (9%)
   • median 48,673 mi at 3.5 yrs old (26 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2001–2007

   Complaints describe the foot-operated parking brake going to the floor or failing to hold on a slope, even on vehicles where it was seldom used. Owners say dealers characterized it as normal wear and charged for an adjustment or replacement of the parking brake shoes, and some note the problem was found only at state inspection. Reported from about 19,000 to 70,000 miles, often on vehicles only a few years old.

   What to check: Set the parking brake on a slight incline during the test drive and confirm it holds; ask whether the parking brake shoes or adjustment have been serviced.

   “I recently tokk my 2001 chev Suburban to the dealership for misc repairs. One of which was that the emergency/parking brake no longer held the vehicle at all. Either in forward or reverse. One day I went to use it and it didn't work at all. How long had it been this way? I rarely, if ever, use the parking brake so I assumed it was broken and would be covered under warranty since the vehicle is only 2.5 years old and only has 18,900 mi. …”

   NHTSA complaint #10062106, filed 2004-03, 18,900 miles

   “On 2/12/04, I took my 2001 chevy Suburban in to the dealer because the emergency/parking brake did not work. Being the first time I tried to use it and it did not work, I assumed it would be a warranty repair. The dealer said no, this is common and a normal wear and tear adjustment. I said I have never used it, how can it be! Not being safe w/out a emergency parking brake, I had to pay! After their adjustment the brakes or something squealed. …”

   Brakes

   Rusted metal brake lines leaking, pedal to the floor

   • 33 complaints (8%)
   • median 119,732 mi at 12.9 yrs old (31 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $850 (median of 6 quotes)
   • filed 2005–2016

   Owners describe the steel brake lines, particularly the one running to the left front wheel and the lines between the master cylinder and calipers, rusting through and leaking until the pedal goes to the floor. Several say a shop found every metal line rusted end to end and replaced the whole set. Complaints often note the suddenness of the loss of braking with little warning. Mostly reported between roughly 60,000 and 160,000 miles, with several mentions of salted winter roads.

   What to check: Have the metal brake lines inspected underneath for rust and seepage, especially on vehicles from salted-road areas, and ask whether any lines have been replaced.

   “This is the second time I had to make an emergency stop because of a rusted-thru brake line. This time, I was entering a high-speed merge from one four lane highway to another and traffic was backing up. I had to apply the brakes slightly hard to slow down in time. Pedal went completely to the floor with about 20% of the normal braking power available. Was not going to stop in time and was forced to drive off the road to avoid rear-ending another car and onto the road shoulder at speed. …”

   NHTSA complaint #10605502, filed 2014-06, 136,000 miles

   “Brake failure. Metal brake line between master cylinder and caliper developed a leak due to corrosion of the metal brake line. Mechanic said all metal brake lines were rusted and corroded and needed to be replaced. I understand there is an investigation underway on these faulty lines. The replacement of these lines was very expensive and was definitely a premature failure in my opinion. Luckily my 20 year old son noticed the brake pedal was going to the floor while on the interstate and was able to safely exit the highway. …”

   Fuel system

   Fuel pump failure causing stalling or no-start

   • 69 complaints (16%)
   • median 58,147 mi at 4.0 yrs old (58 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $765 (median of 6 quotes)
   • filed 2001–2019

   Owners report the engine cutting out at speed or refusing to start, sometimes traced to a failed in-tank fuel pump or a fuel delivery fuse. Some describe repeated pump replacements and trouble getting a dealer to honor recall coverage. A few mention difficulty filling the tank, with the pump clicking off repeatedly or fuel overflowing. Typically reported between about 70,000 and 160,000 miles, with some at lower mileage.

   Recall 05V1550001 related service bulletin

   What to check: Ask if the fuel pump has been replaced and whether the fuel module recall applies to the VIN; listen for a long crank or hesitation on start-up.

   “I have a 2001 chevy Suburban k2500, it takes me 45 minutes to fill up the gas tank, I believe the air does not escape from the gas tank and it causes it to overflow when filling and may cause fire if unattended since when you press the gas pump to pump faster it overflows and leaks on the exhaust pipe and could cause fire, also gasoline might do harm to environment while overflowing, so, please help, its winter here where we live and 45 minutes at the gas pump is really something, thank you-valentin”

   NHTSA complaint #10211416, filed 2007-12, 159,000 miles

   “Dt: the contact owns a 2001 Chevrolet Suburban that simply would not start. This happened without any prior incidents and without warning. The contact had the vehicle towed to a local mechanic shop. The mechanic noted there was an internal fuel pump leak. The contact paid out of pocket for the repairs for which the mechanic performed. After repairing the internal fuel pump leak there were no further problems. …”

Buying note. Have a shop inspect the brake lines and rear parking brake before purchase, and confirm which of the open recalls for this model year have actually been completed for the specific vehicle. A pre-purchase inspection that includes a fuel pressure check is worthwhile given how often pump failures come up in complaints.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
