" I had to have my 2005 Toyota 4Runner towed in for what all indications said was a failed Engine Immobilizer ECU...it's the anti-theft system that reads the chip in your key..a very expensive system and requires complete dis-assembly of the dash to even access. There is no bypassing the system, if it fails the car will not run, no how, no way. After they tore down the dash I got the call from Jackie that the problem was with a terminal connection which had worked loose...no replacement of the module needed.. this made sense as the last time I drove it before it would no longer start I hit a VERY bad ridge in the roadway where they were repaving at a pretty good speed..rocked the hell out of the truck.. anyway, while the labor costs still weren't cheap had the ECU been bad I was looking at close to $2000.00. The dealer could have easily stuck me with this and I would have never known.. Honesty still lives at Hendrick ! My hat's off to them...it's my work truck and I had it back 2 days good as new ! Thanks again Hendrick ! "
