Despite owning one, and appreciating "boring" but hitherto reliable, I cannot recommend the Toyota Camry.
Mine is '98, but I'm assured that the same 'Remote Locking' problem afflicts up to 2008 , and perhaps later.
What's the problem ? - randomly sends an UNLOCK pulse through the car, all doors unlock. Great overnight, or in a shopping carpark !
When driving, this also but not always, sets off the hazard (burglar alarm ?) flashers for two or dozens of flashes, not a great safety feature to confuse other drivers...
So far, NO idea, from myself or several Auto sparkies... The best one was 'Manually lock the LH rear door'...as this is the actuator most likely to play up, apart from the driver's door one. That fix lasted a 3 days.
Shrt story, the system apparantly is both fragile, and almost impo$$ible to trouble-$hoot.
Apart from the actuators being $hundreds, ebay ones are $70 or so. - Reasonable, for a cheap Chinese knock-off, but lets not suggest the BCM, at $2,809 (Genuine, of course). Toyota must surely, be aware that they've had a long-running problem. ?
-That's what one sparky has been reduced to trying for the late model Camry parked in his workshop. For a few weeks so far.
Maybe I'm a grumpy old flatulence, but I reckon such Basic systems should be bullet-proof and last at least as long as the vehicle is registered.
One Call-Out sparkie over here has a website, featuring Camry and another most surprising Jap brand, the mainstay of his business... for the same reason... Remote doors & Immobiliser failures.
A rusty, beaten up old holden or falcon is starting to look good !
