| Engine And Engine Cooling problems |
This vehicle is garage kept and meticulous maintained, has 136,000 miles, original owner, brought to dealer for an oil leak, they said exhaust are frozen and won't come out after heating etc. They have to replace exhaust manifolds! bolts should not seize is the head of a garage kept vehicle that's heated! being a mechanic many years ago I have never seen this happen! this is the first year for the new engine, on a internet search I found it's not uncommon, and the bill is going to cost me over $8000 !. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
My truck is affected by gm’s engine block?heater safety recall (NHTSA 21v?496 / gm n212329840) addressing a risk of short circuit and potential engine?compartment fire at the heater cord/terminal connection. Gm’s interim action has been to remove/disable the block?heater cord, which my dealer did, and then marked the recall “completed. ” as a result, the NHTSA VIN tool shows 0 unrepaired recalls, even though no actual repair/restored functionality exists and gm continues to advise owners not to use the block heater until parts are available. Safety concern / impact: I live in a cold?weather area and purchased this diesel expecting a functioning block heater for reliable cold starts. Disabling the heater has removed an intended cold?weather safety/starting aid for multiple winters without a final fix. Gm’s bulletin explicitly allowed dealers to disable the cord to close the recall, rather than provide a repair, leaving owners without the feature indefinitely. Suspiciously, I have also had to replace glow plugs on this truck sooner than traditional wear / failure rates would demand - including one glow plug that has been replaced twice in short span of time (should have lasted years). I continue to monitor gm’s recall portal; still no parts/remedy schedule. Please review whether gm’s chosen remedy—disabling a safety?related feature and closing the recall—is adequate and within a reasonable time under the safety act. If not, I request NHTSA open a recall query into remedy adequacy and timeliness so owners receive a real repair (replacement heater/cord/connector) or appropriate alternative remedies.
