2003 Chevrolet Astro Problems

What owners report

Owners of this model year most often write about brakes — especially antilock braking that activates at low speed or during parking-lot turns, and brake lines that rust through. A second cluster involves front-end noises (popping or grinding on turns) around the lower ball joints and steering knuckles, and a smaller group covers transmission shifting concerns, charging/electrical faults and a sliding door that will not stay latched open. Many reports come in between roughly 40,000 and 100,000 miles, and some brake-line and front-end reports appear on higher-mileage, older vans.

1. 1
   Brakes

   ABS activates at low speed / brake pedal pulsation

   • 12 complaints (19%)
   • median 67,900 mi at 4.5 yrs old (10 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2005–2013

   Complaints describe the ABS light coming on and the antilock system engaging during slow stops, in parking-lot maneuvers or on dry pavement, with the pedal pulsating or feeling hard and stopping distance increasing. Several owners say a dealer or shop replaced a wheel speed sensor, hub or the ABS control module, and some report the problem returning after repair. A few tie the same symptom to a low-speed left turn where the van shudders or pulls. Mostly reported between about 30,000 and 100,000 miles, often during low-speed braking or turning.

   What to check: During a slow test drive, brake gently in a parking lot and listen or feel for ABS chatter and a light that stays on. Ask for any records of wheel speed sensor, hub or ABS module replacement.

   2 excerpts from owner complaints in NHTSA records

   “On several occasions over the past few months, the ABS light on my van has been coming on and when I apply the brakes, the van jerks around on the road and pulls to the left. I have almost hit other cars on many of these occasions. I had my mechanic look at it recently and he said he checked out the braking system and can see no visible reason for this happening.”

   NHTSA complaint #10238956, filed 2008-08, 95,000 miles

   “I was driving approximately 30 miles per hour along slightly snow-covered road towards stopped traffic at red light on a slight downgrade. I stepped on the brakes gentle, as required by the conditions, but the ABS system started to shudder and the vehicle did not brake at all. I hit a stopped vehicle at the intersection and even with a relatively slow speed impact, our vehicle was written off and the other was towed away because it could not be driven. …”

   Suspension

   Front-end popping or grinding on turns (ball joints)

   • 8 complaints (13%)
   • median 78,400 mi at 8.3 yrs old (4 state mileage, few)
   • filed 2003–2021

   Complaints describe popping, grinding or a violent front-end shimmy when turning or driving at moderate speed, which some dealers traced to the lower ball joints or a steering knuckle. Several owners mention recall 03V328000 for lower ball joint boot interference; some say the noise returned after the recall work, and others report dealers lacked parts or tools to perform it, or that parts were no longer available. Reported across a wide mileage range, from very low miles up to high-mileage vans.

   Recall 03V328000

   What to check: Ask whether recall 03V328000 was completed and keep the paperwork. Turn the wheel fully in both directions at low speed and listen for popping, and have the ball joints checked for play.

   “Our 2003 chevy Astro van had a intermittent very bad shimmy come from the front wheels. It was so bad the van could not be driven over 30 MPH without losing control. The next 20 times it was driven it would work fine. We finally had it in to a dealer who had it happen to one of their mechanic while he was driving. The mechanic said it is a bad ball joint that had to be that way when it left the factory. We have not been able to drive the van for 3 weeks as they say the part is back ordered. …”

   NHTSA complaint #10064263, filed 2004-03, 75 miles

   “Recall 03v328000/lower ball joint boot interference. Consumer had recall repairs done. Whenever vehicle was backing up or making a turn a popping sound was heard while driving. Vehicle had been to the dealer on three separate occasions, and problem recurred.”

   Electrical system

   Charging and electrical faults; wiring chafed by steering

   • 9 complaints (15%)
   • median 79,123 mi at 5.4 yrs old (6 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2005–2017

   Complaints describe a dropping volt gauge, a battery light that stays on, and batteries going dead even after the alternator, battery and cables were replaced. Others report a wiring harness contacting the steering knuckle when turning left, damaging wires and causing the radio, A/C and instrument lights to cut out, or a burned harness near the front tire. Two complaints describe engine fires attributed by the fire department to an electrical short. Reported from about 29,000 miles upward, typically after several years of use.

   3 related service bulletins

   What to check: Check the charging gauge and warning lights on start-up and during the drive, and have the harness near the left front wheel and steering knuckle inspected for chafing or repairs.

   “I have a 2003 chevy Astro. The problem started in january of 2005. The volts meter started dropping. I took it to phil smith Chevrolet in lauderhill, florida. They did an electric diagnostic and found the alternator and battery to be bad. I changed the alternator and battery on my own. Vehicle still had same problem afterwards. I then took my vehicle back to phil smith Chevrolet, and they said that the battery cables were bad. I had them change them. …”

   Brakes

   Rusted brake lines and loss of brake pressure

   • 6 complaints (10%)
   • median 55,673 mi at 6.5 yrs old (6 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2005–2014

   Owners describe the brake pedal going to the floor and fluid loss, then finding a brake line rusted through or worn where it contacts another component. One report describes a line rubbing against the power steering pump, another describes battery acid dripping onto a line below the battery. Repairs were done by independent shops, and in one case the van caught fire after a battery cable arced against a brake line. Generally reported on vans past 60,000 miles, often in salt-belt states or after many winters.

   What to check: Have a shop inspect the steel brake lines along the frame and near the battery and steering pump for rust or rubbing, and check the master cylinder reservoir level before purchase.

   “The brake line rubbed up against the power steering pump, eventually rubbing through. I lost braking power and nearly caused an accident. Within minutes, I went from having brakes to having to push the brake peddle to the floor to stop. I had a local mechanic fix the problem at a substantial cost.”

   NHTSA complaint #10254819, filed 2009-01, 145,000 miles

   “I was driving pulling a trailer on the freeway when suddenly the traffic stop. I applied the brakes at a safe distance when suddenly my brakes when all the way to the floor I applied the emergency brakes and stop. I had to go thru the emergency lane. I told my son to push the brake pedal while I was underneath and the brake lines broke. They where all rusted out. I had to get a wrecker to take it home.if you need to see my van call me so you can see the brake lines.”

   Transmission and drivetrain

   Transmission shudder, harsh or delayed shifts

   • 5 complaints (8%)
   • median 37,010 mi at 3.4 yrs old (4 state mileage, few)
   • filed 2003–2008

   Owners describe jerking or repeated early-then-late shifts when accelerating from a stop or on an incline, and in one case a hum or shudder felt from the rear at highway speed that dealers tried to address with driveline dampers. Another complaint reports transmission failure on the highway with a roar and loss of acceleration, requiring replacement. Complaints note repeated dealer visits for the same shifting concern. Shift-quality reports appear at low miles, some under 35,000; driveline shudder around 25,000–30,000 miles; failure reported near 46,000 miles.

   3 related service bulletins

   What to check: Test drive from a stop on an incline and feel for jerking or delayed engagement, and check for a hum or vibration at 40–60 mph. Ask about fluid service history and any prior transmission work.

   2 excerpts from owner complaints in NHTSA records

   “The following problem existed while the vehicle was under warranty and still exists. This is the 3rd time that it has been to the dealer for the same problem. In the beginning, it felt like my vehicle was shifting too soon and then would shift immediately afterwards. When I slow down or stop in traffic on an incline, the problem is really pronounced. …”

   NHTSA complaint #10163506, filed 2006-07

   “Thursday september 20, 2007 4:30 p.m. . Transmission failure, 200 miles from home in california. Driving on highway, heard roaring sound from engine, would not accelerate speed dropped. Exited freeway looking for mechanical help, none available. Overnight in campground. Next day to local repair shop for diagnosis of transmission failure. Van had to be towed to santa barbara, california. Transmission replaced, sept. 21, '07.”

Buying note. Brakes dominate the complaints for this model year, so a brake-line and ABS inspection by a shop is worth doing before purchase. Also confirm whether recall 03V328000 was performed and check the front end, transmission shift quality and charging system on a test drive.
