At any speed my red air bag light comes on and knocks out the whole instrument panel. This is the 3rd time this has happened. Previous two times the jeep wrangler 1999 was taken to dealer and apparently 'fixed.'

Engine knocking or ticking by model year
What owners say
Experianced headaches, nausea, as well as audible knocking from under hood. My 1999 4.0 liter 6 cylinder was found to have broken exhaust manifold, leaking hot gasses and exhaust into engine compartment and passenger compartment. Dealership aware that there is problem with manifold, as have redesigned it and replacement cost in excess of $500.00 contacted chrysler and filed complaint, told they area aware of problem, but will not stand behind it or issue recall. Local exhaust shop advised they do several per month with this defective exhaust manifold, both wrangler and cherokee between 1996 and 2000 model year. Exhaust was revised in 2000 because of problems, but chrysler will not stand behind product denying the problem is a defect. Chyrsler should warranty this problem as they did with the 2.5 liter. Milage at time was only 39,000 when cracked.
Small crack developed in exhust manifold, causing ticking noise and lowered fuel economy.
When starting up vehicle, it makes a ticking sound due to crack in manifold. Dealer contacted please add VIN.
Exhaust manifold cracked in several places with only 56k on jeep. Dealer says there was no special warranty for this part, but was plenty aware of the high incidence of failure with this part. Independent mechanics shop that repaired my jeep said that his friends shop has repaired several hundred of the same vehicle as mine, just in the orlando florida area. This part should be recalled, dangerous fumes from this obviously defective part could leak into cabin of jeep, possibly knocking out the driver.
Hole in exhaust manifold, annoying ticking noise when driving.
