what we have here are two inter related issues with two complete sets of BULL$#!^ ..sorry misinformation.
Firstly we have the tendancy for pretty much all dealers and all manufacturers, to some degree or another automatically try to blame or dismiss valid warranty claims.
They (dealers) all want to "service" you car at an inflated price, but they most certainly are not the be all and end all experts on the brands and models they service.
Remember most of the time of the service department at any dealer is occupied with very profitable "scheduled services". In a day and age of very reliable vehicles, and vehicles that are getting ever more complex. They repair very little and diagnose even less.
They certainly do not make good money out of warranty repairs, particularly convoluted hard to find problems.
It may
well be that certain mechanics outside of the dealerships know more about the vehicles than the dealers do ....... AND it is far from uncommon for dealers to sub-contract the hard stuff.
I have several friends and aquaintences who are regularly approached to solve problems that dealers cant or won't.
So we have dealer mechanics that are not expert at diagnostics or the systems, who have a pre-inclination to blaming anything else, handling the issue.
There are no doubt many genuine warranty faults that remain unrectifed, because the dealer has sucessfully palmed the customer off.
Second ... the whole aftermarket industry is very variable ....... some of the items are
well designed and proven ....... others have very little real engineering input and even less testing.
I guarantee you in the lower end of the market, bullbars will be designed by the bloke who can drive the profile cutter and welder, with a rubber stamp from an engineer if you are lucky.
Some of the lesser designs most certainly do have airflow issues, and this should have been obvious for anybody with eyes to see.
As for light bars and
driving lights obstructing airflow and causing overheating ...... I've run big lights on my vehicles most of my driving life and never experienced overheating problems ........ that does not mean it's not is not an issue.
IF the airflow is not otherwise compromised, I doubt very much that large
driving lights would cause a problem.
BUT if the air flow is obstructed or otherwise compromised, adding another obstruction in the form of big
driving lights, may push it over the edge.
One thing that must be understood, is, on most modern vehicles, the "grill" is not the only or even the major path of airflow.
In older vehicle designs, the radiator stood mostly above the chassis and above the bumper and the grill was the place where nearly all the air flowed.
On modern vehicle a large portion of the radiator sits below the chassis and the bumper line. In many modern vehicles more air flows below the bumper or even thru the bumper than thru the grill.
This is where some bullbars have a problem ........ I have seen bars that have full width solid faces on the bumper section of the bar ... AND ... below that have full width splash plates that extend down quite some way ..... pretty much blocking the bottom half of the radiator.
It is reasonable that there may be issues with some bullbars, but the obstruction should pretty much be obvious when compared to an unmolested example ....... and one would expect other vehicles with that combination to be having problems.
Above all this requires sound diagnosis, not grasping at straws, blame games.
AND most definitely if the vehicle was operating properly with these accessories fitted for quite some time in the past, it is not them to blame now.

With regard to "dealers" mechanics and diagnostics on should not overlook the fact that most manufacturers have many models/types and that many dealers also represent/sell more than one make of vehicle.
It can be a little much to expect a particular dealers contingent of (say) 3-4 mechanics to be diagnostically on top of the full range of models serviced/problem diagnosed at that workshop.
Whereas "old mate" around the corner may have years of experience with that one particular make/model and can pinpoint a particular problem immediately.

Yes indeed.
One thing that has changed is that in the past the American company designed vehicles did not change much year after year ....... they pretty much trotted out the same car with different sheet metal and upholstery year after year.
So there is not a great deal of substantial mechanical difference between an XP falcon and a Teritory... or between the early 6 cylinder holdens and the last of the comadores.
Currently the Japanese and european designed vehicles may have many models bassed on the one chassis and driveline with different sheet metal and upholstery ..... but each new generation is a compeletely different car.
So while the VW beetle, and the mini cooper are built on the same Audi mechanicals, and many of the same vintage Toyota vehicles are built on the same mechanical base ......... those models are entirely different than models that come before and after.
There are many backyard enthusiasts and small time mechanics that have very detailed knoweledge of particular models or ranges.
There are also independent specialists who may have very detailed knoweledge of particular systems or components ....... and yes most mechanics including dealers subcontract to those specilaists.
there are even some weird specilists like "dash strippers" who the major trades have come in to dismantle and reassemble things so the majore work can be done.
YES the workforce is also very mobile these days ....... It would be unusual to find a mechanic who has spent 20 or 30 years working on the same brand in a dealership these days ....... hell some of the dealers don't even stay with the same brand that long.
