2003 Toyota Tacoma Problems

What owners report

Owners of this model year most often report rust damage to the frame and rear subframe, frequently discovered during routine service, inspections or when the spare tire carrier or rear spring hanger fails. A second cluster involves front suspension ball joints that wear and separate, and a smaller group describes throttle response problems and airbag non-deployment in crashes. Most complaints arrive at higher mileage, though the rust reports appear from roughly 60,000 miles upward.

   Body and structure

   Frame and rear subframe rust perforation

   • 157 complaints (44%)
   • median 123,329 mi at 13.2 yrs old (120 state mileage)
   • 3 mention a crash, fire or injury
   • owner-quoted repair $2,500 (median of 9 quotes)
   • filed 2008–2026

   Owners describe the frame or rear subframe rusting through, sometimes with holes at the rear spring hanger or front frame rail, found during oil changes, state inspections or while working underneath the truck. In several cases the rear spring hanger or the frame itself has cracked or detached, and owners say dealers confirmed the frame needed replacement or advised the vehicle was not safe to drive. Some owners report the corrosion warranty or frame campaign had already expired, or that a vehicle was refused because of how it had been undercoated. Mostly reported between roughly 60,000 and 190,000 miles, with several reports from cold-climate, road-salt states.

   What to check: Inspect both frame rails and the rear subframe and spring hangers closely from below, ideally with a hammer or awl test at the rear spring mounts, and ask for any frame inspection or corrosion-repair paperwork from a dealer.

   “This truck is only 11 years old and the frame is rusted out. There is a hole about 12 inches long in the frame rail, on the right side, which caused my shock mount to break in the rear of the truck. I called Toyota and they won't do anything about it. I told them I would never buy another Toyota. This frame should last longer than 11 years.”

   Suspension

   Front lower ball joint wear and separation

   • 31 complaints (9%)
   • median 143,250 mi at 10.3 yrs old (18 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2005–2026

   Complaints describe the front lower ball joint wearing loose or separating, in some cases letting the front wheel detach or causing loss of steering control at road speed. Owners report the truck being towed and diagnosed with a failed ball joint, and some note that the vehicle identification number was included in a suspension recall. Others describe steering that felt loose or required more effort before the failure. Reported from about 75,000 to 275,000 miles, generally as the truck ages.

   Recall 05V225000

   What to check: Have the front lower ball joints checked for play and torn boots before buying, and ask whether the ball joint recall work has been performed.

   “I was driving down the road goimg about 35 MPH heard a loud noise. Lost all control of the steering wheel and my tire had broken off from the ball joint. The place fixing it said the other side is about to break as well. This is very dangerous and I could have been killed.”

   Vehicle speed control

   Accelerator and throttle body response problems

   • 34 complaints (9%)
   • median 98,500 mi at 9.8 yrs old (28 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $1,400 (median of 9 quotes)
   • filed 2004–2023

   Owners describe the accelerator becoming unresponsive over part of its travel, intermittent stumbling or hesitation at various speeds, and in a few cases the pedal sticking down or the engine revving unexpectedly. Complaints mention throttle body diagnosis, a check engine light in some instances, and that the problem could not always be duplicated at the dealer. Mostly reported between about 90,000 and 240,000 miles.

   What to check: Test the accelerator through its full travel at low and cruising speeds and ask whether the throttle body has been cleaned or replaced.

   “Coming to a stop approx 2 MPH the engine suddenly revved very loudly and the truck show forward. The brakes did not stop the truck. I swerved to avoid the campsite we were at and hit a tree very hard. The engine however continued to rev loudly and I shifted to park. With the engine still very loud and the wheels spinning I had to shut the engine by removing the key.”

   NHTSA complaint #10532725, filed 2013-07, 188,707 miles

   “While driving down the highway, I moved into the left lane to pass another car. When I stepped on the accelerator the nose pitched forward and the engine felt like it was not getting any gas. I was able to press the accelerator nearly all the way to the floor to continue getting power to the engine, but the first 2/3 of the pedal stroke were completely unresponsive. A check engine light came on and it was diagnosed as a throttle body issue. After doing some research, this seems to be a well documented issue on a number of Tacoma forums. …”

   Air bags

   Airbags not deploying in a crash

   • 20 complaints (6%)
   • median 39,750 mi at 4.5 yrs old (14 state mileage)
   • 19 mention a crash, fire or injury
   • filed 2003–2024

   Complaints describe frontal and rollover collisions in which neither airbag deployed, sometimes with injuries to occupants. Owners typically raise the issue after the crash rather than as a warning beforehand, and some note there was no passenger airbag cutoff switch on their truck. Reported across a wide mileage range, including trucks under 10,000 miles.

   What to check: Ask for the vehicle's crash history and check for an active airbag warning light or stored airbag fault codes during a pre-purchase scan.

   “I rear ended another vehicle on the interstate driving approximately 65mph, and my air bags did not deploy, luckily everybody had their seat belts on and nobody got hurt.

   • median 127,000 mi at 10.9 yrs old (20 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2010–2026

   Owners report the spare tire dropping out from under the truck while driving, with the carrier plate found heavily rusted. Several mention the spare tire carrier recall, and some say the recall was not performed because of subframe rust or because their vehicle was not included. Reported from roughly 46,000 to 236,000 miles, often in rust-belt areas.

   Recall 12V542000

   What to check: Inspect the spare tire carrier and its mounting plate for rust and confirm with a dealer whether the spare tire carrier recall applies to the vehicle.

   “2003 Toyota Tacoma was recalled in april 2010 for frame replacement. The truck failed and the entire frame was replaced. July 18, 2011, while driving this truck the spare tire falls out from beneath the vehicle. Thankfully I was on a side road going about 35 MPH and the other vehicles on the road were able to avoid any impact. The next day I took the plate that was holding the spare tire to the Toyota service center that replaced the frame. …”

Buying note. Frame rust is the dominant thing to check on this model year, so have the frame and subframe inspected from below before buying, and confirm which recalls and any frame-related service campaigns have actually been completed.
