2003 Toyota Tacoma Recalls (Recent)

Body, Interior & Misc., November 23, 2012

RepairPal Expert Overview:

Vehicles currently registered, or first sold in states where salt is used to de-ice the roads, are being recalled because a metal plate which helps secure the spare tire may rust excessively and break. This rust condition is a result of an insufficient coating of anti-corrosion material during the manufacturing process. If the plate were to break, the spare tire would come loose and fall from the vehicle while driving. Toyota is currently developing a remedy for this recall and will notify owners of affected vehicles when the remedy is in place. This is expected during December of 2012.

2003 Toyota Tacoma Reviews

Since new in '03 I've put 93K. Took it to the dealer after 5 yrs of cautious avoidance. They said an "open recall for frame corrosion" would get me a
free undercoating. The check engine lamp has been on ever since = code
P-042 "OS2 sensor bank one". Found to be sending 100% properly. That poor guy in Arizona : If it aint (isn't) broke DONT FIX IT ! I live in fear of having to
buy anything or trust anyone now...What a drag. ~ JD

Gas mileage sucks! Stock 17.5 mpg hwy I added K/N filter and cold intake with minor difficulty for a whopping 20mpg! My friends have Dodge diesel 4x4s that get 21. Front wheel wells on this model have openings that collect leaves and has to be cleaned regularly to prevent rust. Paint job chips, scratches and stains very easily. I keep teflon wax on it but the paint is bad. A/C is only fair and I have had it checked by pros. Stock brakes sucked (dealer did them twice before 30k) so I went proactive and installed drilled and slotted front discs along with ceramic pads to great effect! Electronic tranny button is worthless, nobody can figure out what its use or need is. Complained to the factory about these problems and they told me I was the only person to do so. Was told by the dealer that only auto trans was avail in my model. My next truck will be a manual even if I have to buy used. Door lights would be great as my friends tell me they cannot see my open doors at night. Other than that it is a great truck and I expect to have it for at least 5 more years before I move up to a cab over for camping.

The problem with my 2003 Toyota Tacoma misfiring after a preventative maintenance timing belt replacement was solved. It turned out to be a broken/missing sensor tooth on the crankshaft position-timing belt wheel. How it happened?...don't know, probably done on belt removal or installation. The P/U has been running fine since bought new in 2003 and 97000 miles on the odometer. The ignigter and ECM were ok as were the coils. Very nice, dependable truck and the A/C works fine , even here in hot, dry Arizona.

At 97000 miles I took the P/U to a local garage to have timing belt and all other belts replaced as preventative maintenance. The mechanical part went well but the engine was missing when started. Diagnosis resulted in that coil for cyls 1-4 was not firing. Test showed that signal from the ignighter on fired once, the other two coils fired ok. Subtitution with a known good igniter resulted in the same misfire. That leave the EMC in question. The p/u was running perfect when it entered the garage. The head head mechanic and help are all scratching their heads and I'm without a P/u. Sounds to me as rule #1...disconnect the battery ground when doing work on the engine was not done. What say you?

Reliable TOYOTA!!
