2015 Chevrolet Impala Engine Problems

Your parked, turned-off Impala caught fire at the front of the vehicle while unoccupied. The fire department extinguished the fire and indicated it may have resulted from a mechanical malfunction, though the vehicle was completely destroyed before diagnosis. The cause was never identified or repaired since the vehicle couldn't be salvaged. A repair would require a complete engine and electrical system inspection to identify what component failed and caused the fire.

Your car is stalling unexpectedly while driving at various speeds without any warning lights. Sometimes it restarts on its own, but other times you need to restart it manually, and in at least one case it had to be towed home. Two dealers were unable to reproduce or identify the problem. The issue may involve fuel delivery, ignition timing, or engine sensors that need to be inspected and tested.

Your 2015 Chevrolet Impala is making loud clanking noises from the engine and has a strong gasoline smell, with a visible fuel leak from the engine compartment. The dealer initially repaired the fuel pressure pump, but the problem continued and was later diagnosed as catalytic converter failure, which may require engine replacement. The issue started around 136,000 miles and involves diagnosing and repairing or replacing the fuel system components and catalytic converter.

My left hand (front bank) catalytic converter near the cylinder head fell off yesterday at the mounting flange. It landed in/on my fan. I went online to find a replacement part and found GM service bulletin PIP5419a & b first issued in 2016.. That bulletin explains a known "defect" with the weld. The catalytic converter pipe cracks at the mounting weld. the TSB was issued for all Impalas from 2014-2016, all VINS all transmissions, all 3.6l RPO LFX engines. It says that GM is working on a solution for this concern. Why isn't there a recall on this defect? The file I've attached is not from my car but from the TSB. It's very similar to what my cars catalytic converter looks like.

WHEN ACCELERATING, THE VEHICLE REVS TO HIGH RPMS AND A LOSS OF POWER TO THE WHEELS OCCURS. THIS HAPPENS MOST NOTABLY WHEN ACCELERATING TO PASS WHILE CRUISING AT SPEEDS OF 50MPH AND UP. CHECK ENGINE LIGHT APPEARED AND CODE P16CF WAS GIVEN AND TRACKED DIRECTLY TO THE VARIABLE TIMING OIL CONTROL VALVE.

GM REIMBURSED ME FOR ONE OF TWO REPAIRS NEEDED TO FIX A PROBLEM THAT CAUSED THE CHECK ENGINE LIGHT TO TURN ON. THESE TWO REPAIRS WERE PERFORMED THREE MONTHS PRIOR TO GM'S JULY 2018 LETTER ADVISING ME OF ADDITIONAL PROTECTION FOR MY 2015 IMPALA. I WAS DENIED REIMBURSEMENT FOR THE FIRST FIX IDENTIFIED BY THE CAR'S COMPUTER TO REPLACE THE EVAC CANISTER VENT VALVE SOLENOID COSTING $198.77. I WAS REIMBURSED FOR THE SECOND FIX TO REPLACE THE PURGE VALVE COSTING $147.55. IN APRIL 2018, GM HAD NOT IDENTIFIED ANY FIX OTHER THAN THE ONES IDENTIFIED BY MY CAR'S COMPUTER. THEREFORE, BOTH MY REPAIRS WERE PERFORMED TO FIX THIS PROBLEM AND SHOULD HAVE BEEN REIMBURSED AS FIXES FOR THE INOPERATIVE PURGE SOLENOID ADDITIONAL PROTECTION GM IDENTIFIED IN ITS JULY 2018 LETTER TO ME.
